Lip Balm Containing Propolis Better Than Aciclovir Cream in Treating Cold Sores

Comparative Study with a Lip Balm Containing Propolis Special Extract GH 2002 0,5 % vs. Aciclovir Cream 5 % in Patients with Herpes labialis in the Papular / Erythematous stage. A Single-blind, Randomized Two-arm Study

Current Therapeutic Research

Available online 14 October 2017

Background and Objectives

This controlled single-blind trial compared the efficacy of a lip balm with propolis special extract GH 2002 at a concentration of 0.5 % in the treatment of episodes of Herpes labialis with that of aciclovir 5% cream.

Patients and Methods

Patients in the erythematous/papular stage were randomized to two groups: 189 patients were treated with propolis cream, 190 patients with aciclovir (ITT population). Application was five times daily. The primary parameter was the difference in median time to complete encrustation or epithelization of lesions. Secondary parameters were the development of typical Herpes symptoms (pain, burning and itching, tension and swelling), the global assessment of efficacy, and the safety of application.

Results

The predefined clinical situation was reached after a median of four days with propolis and after five days with aciclovir (p < 0.0001). Significant differences in favor of the study preparation were also found with all secondary parameters and symptoms. No allergic reactions, local irritations or other adverse events were observed.

Conclusions

Propolis GH 2002 extract lip balm 0.5 % was found superior in the treatment of episodes of Herpes labialis over aciclovir cream 5 % in patients in the papular/erythematous phase upon inclusion.

Pollen Diversity of Bee Bread Is Linked to Its Nutrient Content

Nutritional composition of honey bee food stores vary with floral composition

Oecologia, First Online: 14 October 2017

Sufficiently diverse and abundant resources are essential for generalist consumers, and form an important part of a suite of conservation strategies for pollinators. Honey bees are generalist foragers and are dependent on diverse forage to adequately meet their nutritional needs. Through analysis of stored pollen (bee bread) samples obtained from 26 honey bee (Apis mellifera L.) hives across NW-England, we quantified bee bread nutritional content and the plant species that produced these stores from pollen.

Protein was the most abundant nutrient by mass (63%), followed by carbohydrates (26%). Protein and lipid content (but not carbohydrate) contributed significantly to ordinations of floral diversity, linking dietary quality with forage composition. DNA sequencing of the ITS2 region of the nuclear ribosomal DNA gene identified pollen from 89 distinct plant genera, with each bee bread sample containing between 6 and 35 pollen types. Dominant genera included dandelion (Taraxacum), which was positively correlated with bee bread protein content, and cherry (Prunus), which was negatively correlated with the amount of protein. In addition, proportions of amino acids (e.g. histidine and valine) varied as a function of floral species composition.

These results also quantify the effects of individual plant genera on the nutrition of honey bees. We conclude that pollens of different plants act synergistically to influence host nutrition; the pollen diversity of bee bread is linked to its nutrient content. Diverse environments compensate for the loss of individual forage plants, and diversity loss may, therefore, destabilize consumer communities due to restricted access to alternative resources.

VIDEO: Gerard Butler Almost Had A Fatal Overdose...Of Bee Venom

By James McClure  |  Oct 13, 2017 

Gerard Butler is lucky to be alive after nearly suffering a fatal overdose...of bee venom. No, the Scottish actor wasn't partying too hard near an apiary when he decided to shoot up with stingers. He turned to venom to cope with the strain of working on the set of 'Geostorm,' which opens next weekend.

"I had a lot of inflammation," Butler told Seth Meyers yesterday. "I was hanging a lot on wires in this 65 pound space suit, and that's fine for a couple hours, but after five weeks, you're hurting."

So he turned to his nutritionist, who recommended taking bee venom, which supposedly has anti-inflammatory compounds that could've helped Butler battle through the gruelling shoot if it'd been injected properly. But the bee-venom dealer that he flew in wasn't very good at his job. And yes, Butler realizes how sketchy this whole situation sounds in retrospect...

Beeswax Helps Treat Burns

The effect of a beeswax, olive oil and Alkanna tinctoria (L.) Tausch mixture on burn injuries: An experimental study with a control group

Complement Ther Med. 2017 Oct;34:66-73

OBJECTIVES:

This study was planned to investigate the effect of a mixture of beeswax, olive oil and A. Tinctoria (L.) Tausch on burn wounds to determine the impact on burn healing, pain during dressing changes and duration of hospital stay.

METHODS:

The study was conducted between May 2014 and August 2015 in the Burn Unit of Ataturk University Research Hospital. The sample of this experimental study consisted of 64 patients (31 experimental group and 33 control group) who met its inclusion criteria. While the specially prepared dressing material was applied to the experimental group, the control group was administered the clinic's routine dressing. The injuries were photographed before each dressing. Each picture was uploaded to a computer for measurement with ImageJ software...

When a beeswax, olive oil and A. tinctoria (L.) Tausch mixture was applied to second degree burns, this accelerated epithelization, reduced the pain experienced during dressing changes and shortened the hospital stay durations of the patients.

Honey Helps Treat Contact Lens Induced Dry Eye

Treatment of contact lens related dry eye with antibacterial honey

Contact Lens and Anterior Eye

Available online 9 October 2017

Aim

Contact lens induced dry eye affects approximately 50% of contact lens wearers. The aim was to assess the effects of Manuka (Leptospermum sp.) honey eye drops (Optimel, Melcare, Australia) on dry eye in contact lens wearers. The safety of the honey eye drops in contact lens wear and contact lens wearers’ compliance were also evaluated.

Design

Prospective, randomised, cross over study, examiner masked, pilot treatment trial.

Methods

Twenty-four participants aged 20 to 55 years with contact lens related dry eye were recruited and randomised to two treatment groups; 20 completed the study. One group used Optimel eye drops twice a day for two weeks followed by conventional lubricant (Systane Ultra, Alcon) therapy for two weeks; the other group completed the treatments in the reverse order. Before and after each treatment dry eye symptomology, ocular surface inflammation, and tear quantity and quality were assessed. Participants completed a daily log detailing their usage of treatments and any issues.

Results

Dry eye symptoms improved significantly after Optimel treatment. Patients with more severe symptoms at baseline showed a greater improvement in symptoms. No significant differences were observed in the objective signs of dry eye; presumably because of the short treatment duration. Seventy-five% of contact lens wearers reported good adherence to Optimel treatment and 95% reported no issues using this product.

Conclusions

Optimel Eye Drops reduce the symptoms of dry eye in contact lens wearers and are safe to use. A longer treatment period to assess the effect on clinical signs of dry eye is required.

Propolis Boosts Immunity

Propolis supplementation attenuates the negative effects of oxidative stress induced by paraquat injection on productive performance and immune function in turkey poults

Poultry Science
Published: 05 October 2017 

Paraquat (PQ) is used as a herbicide in agriculture and causes oxidative and inflammatory damage to animal tissues. The current study was conducted to investigate the positive effects of dietary propolis (PR), as a potent naturally produced antioxidant, on growth performance and immune function of turkey poults exposed to oxidative stress induced by PQ injection.

Native male turkey poults (n = 120, 49-d-old) were randomly assigned into 4 groups: poults received a basal diet with a daily subcutaneous PQ injection of 5 mg/kg BW for 7 consecutive days (PQ group), an experimental diet containing 1 g/kg PR with a daily subcutaneous PQ injection for 7 days (PR+PQ group), or received the experimental PR diet with a daily subcutaneous injection of 0.5 mL sterile saline for 7 days (PR group); while the control poults received a basal diet with a daily subcutaneous saline injection for 7 consecutive days (C group). The productive performance in the PQ group showed a significant (P < 0.05) reduction in the weight gain (WG) and feed intake (FI), and impaired feed conversion ratio (FCR). Propolis supplementation in the PR+PQ group significantly ameliorated the PQ effects on WG and FCR. Turkey poults of the PQ and PR+PQ groups had a significant augmentation in the blood malondialdehyde (MDA), tumor necrosis factor-α (TNFα), and corticosterone levels, and in contrast, a significant reduction in the triiodothyronine (T3), when compared to the C group.

While propolis significantly reduced the MDA and corticosterone, and increased the T3 levels in the PR+PQ group compared to the PQ group. Furthermore, the dietary PR supplementation significantly limited the PQ-suppressive effects on cell- and humoral-mediated immunity and lymphocyte proliferation of turkey poults. In addition, propolis supplementation in the PR and PR+PQ groups markedly reversed the PQ-induced DNA fragmentation and heat shock protein 70 (Hsp70) over-expression in blood cells.

It can be concluded that PR could improve turkey immunity and performance, particularly under inflammation and oxidative stress induced by PQ exposure.

Manuka Honey May Be Effective in Treating Atopic Dermatitis Lesions


Manuka honey tested as AD treatment
Pilot study shows evidence of healing in atopic dermatitis

Dermatology Times, October 06, 2017

An open-label, pilot study has found that the topical application of manuka honey may be effective in treating atopic dermatitis lesions.

Abdullah A. Alangari M.D., the study’s lead author and an allergist at King Saud University in Saudi Arabia, says he was prompted to investigate the impact of honey after receiving anecdotal reports from patients saying they benefited from using honey to treat atopic dermatitis lesions. The study appears in a recent issue of Immunity, Inflammation and Disease.

Honey is well-recognized for its medicinal qualities and is currently being employed in wound care and as a burn treatment. Other studies have shown that it can provide antibiotic resistance to specific strains of bacteria. It's health properties are continually under study throughout the world.

In this study, investigators recruited 16 individuals (8 female, mean age 33), but two withdrew due to worsening symptoms. “We asked patients with bilateral atopic dermatitis lesions to place honey topically on one site overnight and leave the contralateral site untreated. We noted that on average the lesions treated with honey improved more than lesions that were untreated,” he said...

Royal Jelly May Help Treat Milk Allergy

Preventive effects of royal jelly against anaphylactic response in a murine model of cow's milk allergy

Pharm Biol. 2017 Dec;55(1):2145-2152

CONTEXT:

Royal jelly (RJ) has long been used to promote human health.

OBJECTIVE:

The current study investigated the preventive effects of RJ against the development of a systemic and intestinal immune response in mice allergic to cow's milk proteins.

MATERIALS AND METHODS:

Balb/c mice treated orally for seven days with RJ at doses of 0.5, 1 and 1.5 g/kg were sensitized intraperitoneally with β-lactoglobulin (β-Lg). Serum IgG and IgE anti-β-Lg were determined by an enzyme-linked immunosorbent assay (ELISA). Plasma histamine levels, symptom scores and body temperature were determined after in vivo challenge to β-Lg. Jejunums were used for assessment of local anaphylactic responses by an ex vivo study in Ussing chambers and morphologic changes by histological analysis.

RESULTS:

RJ significantly decreased serum IgG (31.15-43.78%) and IgE (64.28-66.6%) anti-β-Lg and effectively reduced plasma histamine level (66.62-67.36%) (p < 0.001) at all the doses tested. Additionally, no clinical symptoms or body temperature drops were observed in RJ-pretreated mice. Interestingly, RJ significantly reduced (p < 0.001) intestinal dysfunction by abolishing the secretory response (70.73-72.23%) induced by sensitization and prevented length aberrations of jejunal villi by 44.32-59.01% (p < 0.001).

DISCUSSION AND CONCLUSIONS:

We speculate that using RJ may help prevent systemic and anaphylactic response in allergic mice. These effects may be related to its inhibitory effects on the degranulation of mast cells.

Honey Better than Phenytoin for Healing Episiotomy Wounds

Comparison of honey and phenytoin (PHT) cream effects on intensity of pain and episiotomy wound healing in nulliparous women

J Complement Integr Med. 2017 Oct 5

Background

This study investigates and compares the effect of phenytoin and honey cream on intensity of pain and episiotomy wound healing in nulliparous women.

Methods

This research was conducted by double-blinded randomized clinical trial method on 120 nulliparous women in three groups of phenytoin, honey and placebo. After delivery and episiotomy, mothers used a knuckle of the prescribed creams on their episiotomy area, every night until 10-night. Evaluation of wound healing using REEDA scale and pain intensity with numerical rating scale of pain took place within the first 24 h and after 7 and 14 days of delivery.

Results

Results showed significant differences between healing scores of the three groups for the seventh day after delivery. Healing score in the honey group was lower than that in placebo group. On the fourteenth day after delivery, the healing scores showed no significant differences between the three groups. Measuring pain intensity did not show any significant difference in the three groups after 7 and 14 days of delivery.

Conclusions

Both honey and phenytoin led to episiotomy wound healing; however, honey caused the wound healing better than the phenytoin. Honey and phenytoin did not reduce episiotomy pain.

Methicillin Resistant Staphylococcusaureus (MRSA) and Methicillin Sensitive Staphylococcus aureus (MSSA) Isolates Sensitive to Honey

Antimicrobial Activity of Honey with Special Reference to Methicillin Resistant Staphylococcus aureus (MRSA) and Methicillin Sensitive Staphylococcus aureus (MSSA)

J Clin Diagn Res. 2017 Aug;11(8):DC05-DC08

INTRODUCTION:

Antimicrobial agents are essentially important in reducing the global burden of infectious diseases. With the irrational and excessive use of antibiotics in underdeveloped and developing countries, there may be chances to develop and spread resistant pathogens in the community. As a result, the effectiveness of the antibiotics is diminishing. Therefore, the need for novel alternative antimicrobial strategies has renewed interest in natural products like turmeric, honey, ginger and others exhibiting antibacterial properties. This situation has led to a re-evaluation of the therapeutic use of ancient remedies like honey as no other studies are available in the state of Andhra Pradesh with the locally available honey.

AIM:

To find out the efficacy of antibacterial activity of locally available honey against Methicillin Resistant Staphylococcusaureus (MRSA) and Methicillin Sensitive Staphylococcus aureus (MSSA) isolates.

MATERIALS AND METHODS:

A prospective study on the antibacterial activity of Bharat multi floral pasteurised honey which was locally available in the state of Andhra Pradesh, further it was conducted and evaluated against the bacterial strains of Methicillin Resistant Staphylococcus aureus and Methicillin Sensitive Staphylococcus aureus. Their antibacterial sensitivity pattern was tested using Kirby-Bauer disc diffusion susceptibility testing technique of CLSI along with other commonly used antimicrobials.

RESULTS:

Both MRSA and MSSA isolates were sensitive to honey. But MRSA were resistant to all antimicrobials tested except linezolid where as MSSA were sensitive to all except penicillin.

CONCLUSION:

It is definitely worthy to consider honey as a promising future antimicrobial to be tested and studied. Honey, may be elaborately used in future with some more molecular studies on its method of action as an antimicrobial agent.

Evaluation of bioactive compounds potential and antioxidant activity of brown, green and red propolis from Brazilian northeast region

Food Res Int. 2017 Nov;101:129-138

The aim of the present study was to determine the contents of bioactive compounds present in brown, green and red species of propolis cultivated in the Brazilian northeast states of Alagoas and Sergipe. The contents of phenolic compounds, flavonoids and antioxidant activity (DPPH, ABTS+, FRAP, ORAC) were determined. Identification and quantification of phenolic and flavonoid compounds were performed by using UHPLC-QqQ-MS/MS system. The results revealed high contents of total phenolics and flavonoids. Among the three species, the antioxidant potential had higher capacity in the red propolis. The presence of some of bioactive compounds viz. acacetin, artepellin C, eriodictyol, gallic acid, isorhamnetin, protocatechuic acid, vanillin and vanillic acid in Brazilian red propolis is reported for the first time in this work. Positive correlation between total phenolics versus the FRAP and ORAC methods was established which led to conclusion that antioxidant activity of propolis is mainly due to its phenolic compounds.

Propolis Component May Help Treat Oral Cancer

Apoptosis induced by caffeic acid phenethyl ester in human oral cancer cell lines: Involvement of Puma and Bax activation

Arch Oral Biol. 2017 Sep 25;84:94-99

OBJECTIVE:

Caffeic acid phenethyl ester (CAPE), a natural honeybee product exhibits a spectrum of biological activities including antimicrobial, anti-inflammatory, antioxidant and antitumor actions. The purpose of this research was to investigate the anticancer potential of CAPE and its molecular mechanism in human oral cancer cell lines (YD15, HSC-4 and HN22 cells).

DESIGN:

To determine the apoptotic activity of CAPE and identify its molecular targets, trypan blue exclusion assay, soft agar assay, Western blot analysis, DAPI staining, and live/dead assay were performed.

RESULTS:

CAPE significantly suppressed transformation of neoplastic cells induced by epidermal growth factor (EGF) and 12-O-tetradecanoylphorbol 13-acetate (TPA) without inhibiting growth. CAPE treatment inhibited cell growth, increased the cleavages of caspase-3 and poly (ADP-ribose) polymerase (PARP), and augmented the number of fragmented nuclei in human oral cancer cell lines. CAPE activated Bax protein causing it to undergo a conformational change, translocate to the mitochondrial outer membrane, and oligomere. CAPE also significantly increased Puma expression and interestingly Puma and Bax were co-localized.

CONCLUSION:

Overall, these results suggest that CAPE is a potent apoptosis-inducing agent in human oral cancer cell lines. Its action is accompanied by up-regulation of Bax and Puma proteins.

Royal Jelly Slows Rate of Muscle Strength Decrease in the Elderly

Effects of protease-treated royal jelly on muscle strength in elderly nursing home residents: A randomized, double-blind, placebo-controlled, dose-response study

Sci Rep. 2017 Sep 12;7(1):11416

Although we have found that protease-treated royal jelly (pRJ) benefit for the skeletal muscle mass and strength in the aged animals, the potential beneficial effects have not been evaluated in humans.

The aim of this study was to determine whether pRJ intake had beneficial effects on muscle strength in elderly nursing home residents. One hundred and ninety-four subjects enrolled into this multicenter, randomized, double-blind, placebo-controlled study. Subjects received either placebo(Group 1), pRJ 1.2 g/d(Group 2), or 4.8 g/d(Group 3). Data through 1 year are reported for 163 subjects.

The primary outcome measure is handgrip strength. Secondary outcomes include several physical performance tests (six-minute walk test, timed up and go test, and standing on one leg with eyes closed). The dropout rate was 16.0%. The means (95% confidence interval) of change in handgrip strength for placebo, low-dose, and high-dose groups are -0.98(-2.04,0.08), 0.50(-0.65,1.65) and 1.03(-0.37,2.44) kg (P = 0.06, P for trend = 0.02), respectively. No significant effects of the interventions were observed for physical performances.

These findings suggest that pRJ treatment might not improve, but rather attenuate the progression of decrease in muscle strength in elderly people. In addition, we have not found that pRJ intervention can achieve improvement or attenuating the decrease in physical performance.

Magnolia Berry (Five-Flavor-Fruit) Bee Pollen May Protect Liver, Kidneys From Damage

Protective effect of Schisandra chinensis bee pollen extract on liver and kidney injury induced by cisplatin in rats

Biomed Pharmacother. 2017 Sep 25;95:1765-1776

Cisplatin (CP) has been used to cure numerous forms of cancers effectively in clinics, however, it could induce some toxic effects. Bee pollen is a natural compound, produced by honey bees. It is obtained from collected flower pollen and nectar, mixed with bee saliva.

Bee pollen produced from Schisandra chinensis plants is described to exert potent antioxidant effects and to be a free radical scavenger. The purpose of this study was to investigate the effects of therapeutic treatment with Schisandra chinensis bee pollen extract (SCBPE) on liver and kidney injury induced by CP. The rats were intragastrically administrated with different doses of SCBPE (400mg/kg/day, 800mg/kg/day, 1200mg/kg/day) and vitamin C (400mg/kg/day, positive control group) for 12days, and the liver and kidney injury models were established by single intraperitoneal injection of CP (8mg/kg) at seventh day.

The effect of SCBPE on CP toxicity was evaluated by measuring markers of liver and kidney injury in serum, levels of lipid peroxidation and antioxidants in liver and kidney, observing pathological changes of tissue, and quantified expression of NFκB, IL-1β, IL-6, cytochrome C, caspase3, caspase9, p53 and Bax in liver and kidney. Compared with the model group, the activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and the content of blood urea nitrogen (BUN), creatinine (Cr) in serum all decreased in SCBPE high dose group.

Meanwhile, the activities of superoxide dismutase (SOD), catalase (CAT) and the content of reduced glutathione (GSH) in liver and kidney increased, and the content of malondialdehyde (MDA) and inducible nitric oxide synthase (iNOS) decreased. In addition, the histopathologic aspects showed that the pathological changes of liver and kidney were found in the model group, and SCBPE group reduced to varying degrees. Moreover, the expression of NFκB, IL-1β, IL-6, cytochrome C, caspase3, caspase9, p53 and Bax in liver and kidney decreased.

Therefore, SCBPE could reduce the damage of liver and kidney caused by CP by reducing the level of oxidative stress, and improving the antioxidant, anti-inflammatory and anti-apoptotic capacity of the body.

Bioactive Potential of Cryogel Scaffolds with Manuka Honey

A preliminary in vitro evaluation of the bioactive potential of cryogel scaffolds incorporated with Manuka honey for the treatment of chronic bone infections

J Biomed Mater Res B Appl Biomater. 2017 Sep 27. doi: 10.1002/jbm.b.34002. [Epub ahead of print]

Previous studies have identified honey as an agent in bacterial inhibition and a mediator in lowering the pH at the wound site. Manuka honey (MH), indigenous to New Zealand, contains a Unique Manuka Factor that provides an additional antibacterial agent.

While there are many potential benefits to incorporating MH into wounds, there is currently no ideal way to deliver the material to the site of injury. Cryogels are a type of scaffold that possess high porosity, mechanical stability, and a sponge-like consistency.

This study uniquely incorporates varying amounts of MH into cryogel scaffolds, utilizing its properties in a sustained release fashion to assist in the overall healing process, while using the cryogel structure as a tissue template. All cryogels were evaluated to determine the effects of MH on porosity, swelling potential, mechanical durability, and cell compatibility. The release of MH was also quantified to evaluate bacterial clearance potential, and the scaffolds were mineralized to replicate native bone.

It was determined that a 5% MH silk fibroin cryogel has the potential to inhibit bacterial growth while still maintaining adequate porosity, mechanical properties, and cell infiltration. Such a scaffold would have use in a number of applications, including bone regeneration.

Microwave Heating of Honey Decreases Anti-Bacterial Activity

Microwave processing of honey negatively affects honey antibacterial activity by inactivation of bee-derived glucose oxidase and defensin-1

Food Chem. 2018 Feb 1;240:1131-1136

Microwave (MW) thermal heating has been proposed as an efficient method for honey liquefaction, while maintaining honey quality criteria. However, little is known about the effects of MW thermal heating on honey antibacterial activity.

In this study, we aimed to determine the effects of MW heating on the antibacterial activity of raw rapeseed honeys against Pseudomonas aeruginosa and Staphylococcus aureus, with a particular focus on two major bee-derived antibacterial components, defensin-1 and hydrogen peroxide (H2O2). Our results demonstrated that MW thermal heating completely abolished honey antibacterial activity whereas conventional thermal treatment at 45 and 55°C did not affect the antibacterial activity of honey samples.

A significant decrease in both glucose oxidase activity and H2O2 production as well as defensin-1 amount was observed in MW-treated samples. Given that defensin-1 and H2O2 are regular antibacterial components of all honeys, MW heating may have similar negative effects on every type of crystallized/liquid honey.

Royal Jelly May Help Treat Breast Cancer

The effect of royal jelly on the growth of breast cancer in mice

Oncology Letters

Due to various pharmacological properties, including antioxidative, anti inflammatory and antibiotic properties, royal jelly (RJ) has been widely consumed in daily diets in numerous countries.

In the present study, the effect of RJ on 4T1 bearing mice was investigated. The study was performed by feeding 4T1 bearing mice with RJ using either the prophylactic therapeutic (PTRJ) or therapeutic (TRJ) method.

The experimental results for the PTRJ group demonstrated that the weight of tumor was significantly reduced (RJ 0.5 and 1.5 g/kg); and in the serum, the levels of interleukin (IL) 2 (RJ 0.5 and 1.5 g/kg), interferon (IFN) α, superoxide dismutase (SOD) and total antioxidant capacity (T AOC) were significantly elevated, but the concentrations of IL 4 (RJ 0.5 and 1.5 g/kg) and IL 10 (RJ 1.0 g/kg) were significantly decreased. In addition, the activities of T AOC and glutathione reductase (GR) were significantly improved in the liver, whereas in the kidney, the activities of T AOC and GR were significantly increased only under the dose of 0.5 g/kg. For the TRJ group, the antitumor effect of RJ was not significant; the change in IL 2, IFN α, SOD and T AOC levels in the serum, and the change in T AOC and GR in liver were similar to those observed in the PTRJ groups.

RJ treatment was demonstrated to reduce the development of breast tumor in mice, and simultaneously improve the antioxidant capacity of the serum, liver and kidney, particularly using the prophylactic therapeutic method. These results corroborated the efficacy of RJ supplementation in diets. The results of the present study suggest that the antioxidant and immunomodulatory activities of RJ serve an important role on antitumor growth.

Health Benefits of Manuka Honey as an Essential Constituent for Tissue Regeneration

Curr Drug Metab. 2017 Sep 11

Honey is known for its therapeutic properties from ancient civilizations but only since last few decades its mechanism has been studied on how it causes epithelial regeneration leading to wound and ulcer healing..

In the present review the health perspectives of honey, its chemical composition with special reference to flavonoids, polyphenol composition and other bioactive trace compounds used in tissue regeneration have been highlighted. Honey can inhibit carcinogenesis by moderating with molecular processes of initiation, advancement and progression stage of cancer cells, therefore it is considered a promising anti-cancer agent. Several, well-intentioned characteristics have drawn the attention of researchers to check copious endowed-biological activities of Manuka honey, including antioxidant, antimicrobial and anti-proliferative capacities against cancer cells. Thus, scientists are trying to use Manuka honey in the area of biomedical and tissue engineering to design a template for regeneration. Naturally derived antibacterial agents, like Manuka honey, contain mixture of compounds, which can influence antibacterial potency.

The non-peroxide bacteriostatic properties of Manuka honey have been formerly associated to the presence of methylglyoxal (MGO). The assimilation of MGO as a functional antibacterial additive during designing a tissue template production would explore its properties as a potential agent for manufacturing tissue regeneration template.

The role of glyoxal (GO) and MGO in the bacterial growth inhibition, and in addition to immunomodulatory role, it also enhances wound healing and tissue regeneration. Researchers should step forward to explore the biomedical application, particularly integration into tissue regeneration templates. Therefore, further studies are fully needed to provide detailed information on active components of Manuka honey and their potential therapeutic efficacy in numerous models of human diseases.

Dried Bee Pollen Shows Very Low Microbial Contamination

Microbial characterization of bee pollen from the Vesuvius area collected by using three different traps

PLoS One. 2017 Sep 21;12(9):e0183208

Flower pollen is collected by honeybee foragers, adhered on their rear legs and transported into the hives in the form of pellets. Once in the hives, bee pollen is moisturised with nectar and bee mouth secretions and due to enzymatically modifications it becomes the so-called bee-bread, the protein reservoir of young bees.

Bee pollen can be artificially removed from bee legs and collected by using specific systems, the bee pollen traps. Bee pollen is commercialized for human consumption as fresh product and after freezing or drying. Although bee pollen is nowadays largely consumed in developed countries, as food or food supplement according to local legislation, little is known on its safety related to microbiological hazards.

In this work, we aimed to characterize for the first time the microbiological profile of Italian bee pollen in fresh, frozen and dried form collected along an entire harvesting season. Moreover, monthly microbiological analyses were performed on frozen (storage at -18°C) and dried (storage at room temperature) bee pollen over a 4 months period.

Further aim of this work was the evaluation of the possible impact on production level of three different traps used for pollen collection. Our results on microbial contamination of fresh and frozen bee pollen show that a more comprehensive microbiological risk assessment of bee pollen is required. On the other side, dried pollen showed very low microbial contamination and no pathogen survived after the drying process and during storage.

Buckwheat Honey Has High Antioxidant Activity

The Protective Effect of Whole Honey and Phenolic Extract on Oxidative DNA Damage in Mice Lymphocytes Using Comet Assay

Plant Foods Hum Nutr. 2017 Sep 19

In this study, the antioxidant activity and the protective effect against hydrogen peroxide-induced DNA damage were assessed for five honeys of different botanical origin. Seven phenolic acids were detected in the honey samples. Ferulic acid was the most abundant phenolic acid detected in longan honey, jujube honey and buckwheat honey. Ellagic acid, p-hydroxybenzoic acid and protocatechuic acid were the main phenolic acids detected in vitex honey.

Of all honey samples tested, the highest total phenolic content and antioxidant activity were found in buckwheat honey, whereas the lowest total phenolic content and antioxidant activity were found in locust honey. Treatment with hydrogen peroxide induced a 62% increase in tail DNA in mice lymphocytes, and all studied honeys significantly inhibited this effect (P < 0.05).

The buckwheat honey with higher antioxidant capability also exhibited super protective effect than others. Phenolic extracts of honey displayed greater protective effects than whole honey in comet assay. The hydrogen peroxide-generated increase in 8-hydroxy-2-deoxyguanosine (8-OHdG) was effectively inhibited by the honeys studied (P < 0.05). Moreover, a dose-effect relationship between honey concentration and its protective effect was clearly observed in this study.

It can be deduced that phenolic acids of honey can penetrate into lymphocytes and protect DNA from oxidative damage by scavenging hydrogen peroxide and/or chelating ferrous ions.

Asiatic Honey Bee (A. cerana) Venom Shows Anti-Fibrinolytic and Anti-Microbial Activity

Anti-fibrinolytic and anti-microbial activities of a serine protease inhibitor from honeybee (Apis cerana) venom

Comp Biochem Physiol C Toxicol Pharmacol. 2017 Sep 13

Bee venom contains a variety of peptide constituents, including low-molecular-weight protease inhibitors. While the putative low-molecular-weight serine protease inhibitor Api m 6 containing a trypsin inhibitor-like cysteine-rich domain was identified from honeybee (Apis mellifera) venom, no anti-fibrinolytic or anti-microbial roles for this inhibitor have been elucidated.

In this study, we identified an Asiatic honeybee (A. cerana) venom serine protease inhibitor (AcVSPI) that was shown to act as a microbial serine protease inhibitor and plasmin inhibitor. AcVSPI was found to consist of a trypsin inhibitor-like domain that displays ten cysteine residues.

Interestingly, the AcVSPI peptide sequence exhibited high similarity to the putative low-molecular-weight serine protease inhibitor Api m 6, which suggests that AcVSPI is an allergen Api m 6-like peptide. Recombinant AcVSPI was expressed in baculovirus-infected insect cells, and it demonstrated inhibitory activity against trypsin, but not chymotrypsin. Additionally, AcVSPI has inhibitory effects against plasmin and microbial serine proteases; however, it does not have any detectable inhibitory effects on thrombin or elastase.

Consistent with these inhibitory effects, AcVSPI inhibited the plasmin-mediated degradation of fibrin to fibrin degradation products. AcVSPI also bound to bacterial and fungal surfaces and exhibited anti-microbial activity against fungi as well as gram-positive and gram-negative bacteria.

These findings demonstrate the anti-fibrinolytic and anti-microbial roles of AcVSPI as a serine protease inhibitor.

Bee Venom May Help Treat Neuropathic Pain


Antiallodynic Effects of Bee Venom in an Animal Model of Complex Regional Pain Syndrome Type 1 (CRPS-I)

Toxins 2017, 9(9), 285

Neuropathic pain in a chronic post-ischaemic pain (CPIP) model mimics the symptoms of complex regional pain syndrome type I (CRPS I). The administration of bee venom (BV) has been utilized in Eastern medicine to treat chronic inflammatory diseases accompanying pain. However, the analgesic effect of BV in a CPIP model remains unknown.

The application of a tight-fitting O-ring around the left ankle for a period of 3 h generated CPIP in C57/Bl6 male adult mice. BV (1 mg/kg ; 1, 2, and 3 times) was administered into the SC layer of the hind paw, and the antiallodynic effects were investigated using the von Frey test and by measuring the expression of neurokinin type 1 (NK-1) receptors in dorsal root ganglia (DRG). The administration of BV dose-dependently reduced the pain withdrawal threshold to mechanical stimuli compared with the pre-administration value and with that of the control group. After the development of the CPIP model, the expression of NK-1 receptors in DRG increased and then decreased following the administration of BV.

SC administration of BV results in the attenuation of allodynia in a mouse model of CPIP. The antiallodynic effect was objectively proven through a reduction in the increased expression of NK-1 receptors in DRG

Health Benefits of Manuka Honey as an Essential Constituent for Tissue Regeneration

Curr Drug Metab. 2017 Sep 11

Honey is known for its therapeutic properties from ancient civilizations but only since last few decades its mechanism has been studied on how it causes epithelial regeneration leading to wound and ulcer healing..

In the present review the health perspectives of honey, its chemical composition with special reference to flavonoids, polyphenol composition and other bioactive trace compounds used in tissue regeneration have been highlighted. Honey can inhibit carcinogenesis by moderating with molecular processes of initiation, advancement and progression stage of cancer cells, therefore it is considered a promising anti-cancer agent. Several, well-intentioned characteristics have drawn the attention of researchers to check copious endowed-biological activities of Manuka honey, including antioxidant, antimicrobial and anti-proliferative capacities against cancer cells. Thus, scientists are trying to use Manuka honey in the area of biomedical and tissue engineering to design a template for regeneration.

Naturally derived antibacterial agents, like Manuka honey, contain mixture of compounds, which can influence antibacterial potency. The non-peroxide bacteriostatic properties of Manuka honey have been formerly associated to the presence of methylglyoxal (MGO). The assimilation of MGO as a functional antibacterial additive during designing a tissue template production would explore its properties as a potential agent for manufacturing tissue regeneration template.

The role of glyoxal (GO) and MGO in the bacterial growth inhibition, and in addition to immunomodulatory role, it also enhances wound healing and tissue regeneration. Researchers should step forward to explore the biomedical application, particularly integration into tissue regeneration templates.

Therefore, further studies are fully needed to provide detailed information on active components of Manuka honey and their potential therapeutic efficacy in numerous models of human diseases.

Research on Honey as Anti-Cancer Agent


New discovery in UAEU research project on cancer-tackling qualities of honey

Researchers at United Arab Emirates University (UAEU) have taken their groundbreaking studies into the role of honey in battling cancer a step further, through new findings that pinpoint its potential impact.

The beneficial effects of Manuka honey — renowned for its anti-bacterial properties and capacity to heal wounds — as an anti-cancer agent were identified in 2013 by a research group headed by Dr. Basel Al-Ramadi, then chair of the Department of Medical Microbiology and Immunology within UAEU’s College of Medicine and Health Sciences (CMHS).

Now further investigation by the team has discovered a particular molecular aspect of breast cancer that this type of honey can combat, paving the way for the development of new understanding about precisely how it can be used to fight one of the world’s most serious diseases, and enhancing UAEU’s reputation for pioneering medical research capable of global impact....

Antioxidant and Cytotoxic Properties of Brazilian Propolis

Antioxidant and cytotoxic activity of propolis of Plebeia droryana and Apis mellifera (Hymenoptera, Apidae) from the Brazilian Cerrado biome

Published: September 12, 2017

Propolis is a complex bioactive mixture produced by bees, known to have different biological activities, especially in countries where there is a rich biodiversity of plant species. The objective of this study was to determine the chemical composition and evaluate the antioxidant and cytotoxic properties of Brazilian propolis from the species Plebeia droryana and Apis mellifera found in Mato Grosso do Sul, Brazil.

In the ethanolic extracts of P. droryana propolis (ExEP-P) and A. mellifera (ExEP-A) acids, phenolic compounds, terpenes and tocopherol were identified as major compounds. Both extracts presented antioxidant activity against the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical, the maximum activities being 500 μg/mL (ExEP-P) and 300 μg/mL (ExEP-A). However, only ExEP-A was able to inhibit lipid peroxidation induced by the oxidizing agent 2,2'-azobis(2-amidinopropane) dihydrochloride (AAPH), which inhibited oxidative hemolysis and reduced the levels of malondialdehyde (MDA) in human erythrocytes for 4 h of incubation. The extracts also reduced the cell viability of the K562 erythroleukemia tumour line, with a predominance of necrotic death.

Thus, it is concluded that the propolis produced by P. droryana and A. mellifera contain important compounds capable of minimizing the action of oxidizing substances in the organism and reducing the viability of erythroleukemia cells.

Manuka Honey Helps Heal Horse Wounds

Manuka honey proves it worth in healing horse wounds, but quality is essential – study
September 13, 2017, Horsetalk.co.nz

The value of manuka honey in helping to heal horse wounds has been shown in an Australian study, but the researchers say its important to use only the highest grades.

The researchers showed that manuka honey can have significant healing properties but not when it has a low Unique Manuka Factor (UMF).

Manuka honey is the only honey graded for antibacterial activity. It is graded against the standard antiseptic phenol.

The UMF scale runs from 0-30 and graded honey will have this on the packaging.

The study team tested whether UMF 20 honey had better effects on healing than UMF 5 honey and generic-store bought honey. They compared the results to healing of untreated wounds treated only with saline as a control.

The researchers also analysed whether the healing was primarily due to manuka honey’s antibacterial effects or because of effects on the cells that help healing.

Professor Andrew Dart, from the University of Sydney School of Veterinary Science, said the research was the most recent of a series of studies investigating the effects of manuka honey on healing of open wounds of horses...

Royal jelly – the nobility’s food

Times of Malta

Nature has provided us with several different ‘superfoods’ that have proven to be beneficial to our overall health and fitness. Nevertheless, Royal jelly (RJ) is more than likely the reigning king… or queen of these natural products.

Most people assume that honey is the only bees’ product we collect from the beehive. However, bees also give us RJ, propolis and pollen. Propolis is a resinous substance that the bees produce from tree glue which is mixed with their saliva. Both propolis and pollen are used in alternative medicine. RJ is a thick, milky-white, creamy liquid secreted from glands of the nurse bees, which is extremely nutritious and complex in its chemical composition...

Gwyneth Paltrow Uses Bee Venom Treatment to Get Rid of Her Scars


Gwyneth Paltrow Swears This Strange Treatment Got Rid of Her Scars
Liz Ritter, September 09, 2017

Gwyneth Paltrow's premiere issue of Goop magazine hit yesterday for pre-order and, besides a pretty revealing cover shot of the star, she gets into something she swears by that may have some people—not too surprisingly—scratching their heads: Bee venom injections in her C-section scar.

As reported on by Us, the 44-year-old shared that, "The doctor stings you [with a live bee] like it's an acupuncture needle. I had it done on my cesarean scar… I had some buckling in the scar, and it really evened it out."

Sounds out there but New York dermatologist Adebola Dele-Michael, MD, says bee venom contains hyaluronidase and other substances, which can soften scar tissue and keloids, but stresses that "caution must be taken with this treatment as some people are allergic to bee venom and may develop anaphylaxis when exposed to bee venom."

Honey Mitigates Radiation-Induced Oral Mucositis in Head and Neck Cancer Patients

Honey Mitigates Radiation-Induced Oral Mucositis in Head and Neck Cancer Patients without Affecting the Tumor Response.

Foods. 2017 Sep 6;6(9). pii: E77

Radiation-induced mucositis is a dose-limiting factor in the effective treatment of head and neck (H amp; N) cancers. The objective of this study was to understand the efficacy of honey in mitigating radiation-induced mucositis and whether it would interfere with tumor control. This was a single-blinded, randomized, controlled study and was carried out in patients with H & N cancer requiring curative radiotherapy (gt;62 Gy (Gray)). The patients meeting the inclusion criteria were randomly assigned to receive either honey ( n = 25) or povidone-iodine (active comparator) ( n = 25) during radiotherapy. Oral mucositis was assessed using the RTOG (Radiation Therapy Oncology Group) grading system before the start, during, and at the end of the treatment by an investigator unaware of the treatment. The results indicate that when compared with the active comparator, honey reduced the radiation-induced oral mucositis, decreased the incidence of intolerable mucositis, treatment breaks, loss of treatment days ( p lt; 0.0001 and lt; 0.0003) and did not affect the radiation-induced tumor response. The clinical observations indicate that honey mitigates the radiation-induced mucositis and does not interfere with tumor cell killing.

Lebanese Propolis Exhibits Significant Cytotoxicity and Anti-Proliferative Activity

Chemical characterization and cytotoxic activity evaluation of Lebanese propolis

Biomed Pharmacother. 2017 Aug 26;95:298-307

Chemical composition, anti-proliferative and proapoptotic activity as well as the effect of various fractions of Lebanese propolis on the cell cycle distribution were evaluated on Jurkat leukemic T-cells, glioblastoma U251 cells, and breast adenocarcinoma MDA-MB-231 cells using cytotoxic assays, flow cytometry as well as western blot analysis.

Liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis revealed that ferulic acid, chrysin, pinocembrin, galangin are major constituents of the ethanolic crude extract of the Lebanese propolis, while the hexane fraction mostly contains chrysin, pinocembrin, galangin but at similar levels. Furthermore chemical analysis was performed using gas chromatography-mass spectrometry (GC-MS) to identify major compounds in the hexane fraction. Reduction of cell viability was observed in Jurkat cells exposed to the ethanolic crude extract and the hexane fraction, while viability of U251 and MDA-MB-231 cells was only affected upon exposure to the hexane fraction; the other fractions (aqueous phase, methylene chloride, and ethyl acetate) were without effect.

Maximum toxic effect was obtained when Jurkat cells were cultivated with 90μg/ml of both the crude extract and hexane faction. Toxicity started early after 24h of incubation and remained till 72h. Interestingly, the decrease in cell viability was accompanied by a significant increase in p53 protein expression levels and PARP cleavage. Cell cycle distribution showed an increase in the SubG0 fraction in Jurkat, U251 and MDA-MB-231 cells after 24h incubation with the hexane fraction. This increase in SubG0 was further investigated in Jurkat cells by annexinV/PI and showed an increase in the percentage of cells in early and late apoptosis as well as necrosis.

In conclusion, Lebanese propolis exhibited significant cytotoxicity and anti-proliferative activity promising enough that warrant further investigations on the molecular targets and mechanisms of action of Lebanese propolis.

Manuka Honey Kills Wound Pathogens

Comprehensive In Situ Killing of Six Common Wound Pathogens With Manuka Honey Dressings Using a Modified AATCC-TM100

Wounds. 2017 Jul 26. pii: WNDS20170726-3

OBJECTIVE:

While Manuka honey in vitro is strongly antimicrobial, there have been, to the best of the authors' knowledge, no studies showing that dressings impregnated with Manuka honey can kill organisms in the dressing itself.

MATERIALS AND METHODS:

The investigators used the American Association of Textile Chemists and Colorists' 100 test methodology to compare honey-impregnated dressings with control dressings (without honey) on the ability to kill common wound pathogens. Organisms were chosen after a review of the causal organisms found in actual wound infections over a 12-month period in a busy outpatient wound clinic.

RESULTS:

Even when the dressings were challenged daily with further inoculated organisms, > 5-log reductions were routinely noted across a range of pathogens, including multiple drug-resistant species using dressings containing Manuka honey relative to the control.

CONCLUSIONS:

The results presented herein show that when well-characterized medical-grade Manuka honey is used in dressings (ie, a minimum of 400 mg methylglyoxal/kg) these dressings can comprehensively kill common wound pathogens associated with infected wounds

Manuka Honey Used to Treat Leg Wounds on Horses


This is how fast manuka honey can heal wounds

Manuka honey with a high UMF rating is significantly more effective than examples with a low rating, or regular honey, in improving wound healing, new research shows.

Researchers at the University of Sydney compared the effectiveness of manuka honey of different UMF (unique manuka factor) ratings (ranging from 5 to 20 depending on antibacterial activity) and ordinary, store-bought honey in healing large, bloody wounds on horses' legs.

They said the results were "quite remarkable" and applicable to humans.

"I have been doing wound-healing studies for many years and if you look across the board there are very few, if any, compounds that have a consistent repeatable effect," Sydney University equine surgical specialist Andrew Dart said...

Propolis and the Treatment of Head and Neck Cancers

Evaluating Antioxidant Capacity of Different Propolis Samples from Konya, Turkey and Their Inhibitory Effect on Head and Neck Cancer Cells

Propolis is a resinous mixture collected and used by the honey bees to construct and repair their hives. The component of propolis varies depend on the type of the plants collected. Propolis and its constituents have been subjected to many studies and are known for their antioxidant, antimicrobial and anticarcinogenic properties. In our study, antioxidant and antitumor capacity of propolis from Konya Sakyatan and Kiziloren regions were investigated. According to our result, Kızıloren propolis sample possesses higher antioxidant component and antioxidant capacity than Sakyatan sample. Accordingly, Kiziloren sample showed antiproliferative effect at much lower doses compared to the Sakyatan sample. Both samples effectively inhibited the migration of cancer cells at their determined IC50 dosages. Obtained data indicates that constituents of propolis can greatly vary from one sample to another even in the same region and propolis selections for cancer prevention and treatment studies should be carefully considered.

Bee Venom May Help Treat Acute Myeloid Leukemia

Honey bee venom combined with 1,25-dihydroxyvitamin D3as a highly efficient inducer of differentiation in human acute myeloid leukemia cells

J Cancer Res Ther. 2017 Jul-Sep;13(3):544-549

PURPOSE:

Most cancer cells exhibit a defect in their capacity to mature into nonreplicating adult cells and existing in a highly proliferating state. Differentiation therapy by agents such as 1,25-dihydroxyvitamin D3(1,25-(OH)2 VD3) represents a useful approach for the treatment of cancer including acute myeloid leukemia. Human myeloid leukemia cell lines are induced to terminal differentiation into monocyte lineage by 1,25-(OH)2 VD3. However, usage of these findings in the clinical trials is limited by calcemic effects of 1,25-(OH)2 VD3. Attempts to overcome this problem have focused on a combination of low concentrations 1,25-(OH)2 VD3 with other compounds to induce differentiation of HL-60 cells. In this study, the effect of honey bee venom (BV) and 1,25-(OH)2 VD3, individually and in combination, on proliferation and differentiation of human myeloid leukemia HL-60 cells were assayed.

MATERIALS AND METHODS:

In this in vitro study, toxic and nontoxic concentrations of BV and 1,25-(OH)2 VD3 were tested using Trypan blue stained cell counting and (3[4, 5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide) assay. In addition, differentiation of cells was assayed using a Wright-Giemsa staining and nitroblue tetrazolium reduction test. Data were analyzed by a one-way analysis of the variance test using SPSS software.

RESULTS:

Our findings showed that both the BV and 1,25-(OH)2 VD3, in a dose and time-dependent manner, caused cell death at high concentrations and inhibited cell proliferation at lower concentrations. About 5 nM of 1,25-(OH)2 VD3 induced differentiation of HL-60 cells to monocytes after 72 h. 2.5 μg/ml of BV suppressed proliferation of HL-60 cells but had not any effects on their differentiation, whereas in combination with 5 nM of 1,25-(OH)2 VD3, it enhanced antiproliferative and differentiation potency of 1,25-(OH)2 VD3.

CONCLUSIONS:

These results indicate that BV potentiates the 1,25-(OH)2 VD3-induced HL-60 cell differentiation into monocytes.

How Honeybee Diet Determines Development Of Queen Bees And Worker Bees

Royal Diet

In honeybee colonies, the queen can easily be identified because she is larger than all of her workers. As it turns out, the early diet of bees determine which bee will be the fertile queen and which will be the sterile workers.  

The prevailing view when it comes to the development of honeybees' social status is that what they eat as larvae determines whether they will become the fertile queen or one of the sterile workers. Now researchers are close to understanding just how honeybee diets affect their future roles in the colony.

Manuka Honey May Help Treat Breast Cancer

The IL-6/STAT3 Signaling Pathway Is an Early Target of Manuka Honey-Induced Suppression of Human Breast Cancer Cells

Front Oncol. 2017 Aug 14;7:167

There is renewed interest in the potential use of natural compounds in cancer therapy. Previously, we demonstrated the anti-tumor properties of manuka honey (MH) against several cancers. However, the underlying mechanism and molecular targets of this activity remain unknown.

For this study, the early targets of MH and its modulatory effects on proliferation, invasiveness, and angiogenic potential were investigated using two human breast cancer cell lines, the triple-negative MDA-MB-231 cells and estrogen receptor-positive MCF-7 cells, and the non-neoplastic breast epithelial MCF-10A cell line. Exposure to MH at concentrations of 0.3-1.25% (w/v) induced a dose-dependent inhibition of the proliferation of MDA-MB-231 and MCF-7, but not MCF-10A, cells. This inhibition was independent of the sugar content of MH as a solution containing equivalent concentrations of its three major sugars failed to inhibit cell proliferation. At higher concentrations (> 2.5%), MH was found to be generally deleterious to the growth of all three cell lines. MH induced apoptosis of MDA-MB-231 cells through activation of caspases 8, 9, 6, and 3/7 and this correlated with a loss of Bcl-2 and increased Bax protein expression in MH-treated cells.  

Incubation with MH induced a time-dependent translocation of cytochrome c from mitochondria to the cytosol and Bax translocation from the cytosol into the mitochondria. MH also induced apoptosis of MCF-7 cells via the activation of caspases 9 and 6. Low concentrations of MH (0.03-1.25% w/v) induced a rapid reduction in tyrosine-phosphorylated STAT3 (pY-STAT3) in MDA-MB-231 and MCF-7 cells. Maximum inhibition of pY-STAT3 was observed at 1 h with a loss of >80% and coincided with decreased interleukin-6 (IL-6) production. Moreover, MH inhibited the migration and invasion of MDA-MB-231 cells as well as the angiogenic capacity of human umbilical vein endothelial cells.

Our findings identify multiple functional pathways affected by MH in human breast cancer and highlight the IL-6/STAT3 signaling pathway as one of the earliest potential targets in this process.

Propolis in the Prevention of Oral Mucositis in Breast Cancer Patients

Propolis in the prevention of oral mucositis in breast cancer patients receiving adjuvant chemotherapy: A pilot randomised controlled trial.

Eur J Cancer Care (Engl). 2017 Aug 25

Chemo-induced oral mucositis (OM) is associated with significant symptoms, treatment delays and increased costs. This pilot randomised controlled trial aimed at evaluating the safety, tolerability and compliance with propolis in breast cancer patients receiving doxorubicin and cyclophosphamide, testing preliminary clinical efficacy of propolis in the prevention of OM, and prospectively evaluating the incidence of OM. Sixty patients were randomised to receive either a dry extract of propolis with 8%-12% of galangin plus mouth rinsing with sodium bicarbonate (experimental arm), or mouth rinsing with sodium bicarbonate (control arm). OM was evaluated with the NCI-CTCAE v4.0 after 5, 10, 15 and 21 days of treatment. Compliance with, tolerability of propolis and adverse events were recorded. The incidence of OM was also prospectively evaluated for 6 months. Two patients (6.7%) manifested a suspected skin reaction to propolis. No patient in the experimental arm developed OM > G1, while in the control arm OM > G1 was 16.7% (p = .02). The incidence of OM ≥ G1 at the end of cycles 2-8 was higher at the second (25%) and fifth cycles (45.8%). Propolis plus bicarbonate was safe, well tolerated and promisingly effective in the prevention of OM in patients with breast cancer.

Fitoterapia. 2017 Aug 23. pii: S0367-326X(17)31118-8

The present study aimed to investigate chemical profile, antioxidant and antimicrobial activities of Indian Melifera propolis (IMP) samples collected from 13 different states. Chemical characterisation of ethanolic extracts of IMP (EEMP) samples was carried out by using HPLC and 1HNMR spectroscopy. The antioxidant activity of EEMP samples was measured by DPPH, ABTS, and FRAP assay. Moreover, antimicrobial activity of each EEMP sample tested against bacteria and yeast using a 96 well plate microdilution method. All EEMP samples had remarkable antioxidant and antimicrobial activities.

The antioxidant potential of EEMP samples found to have moderate positive correlation with their total phenolics and flavonoids content. Majority of EEMP samples had minimum inhibitory concentration (MIC) ≤1mg/mL against Staphylococcus aureus. Chemometric analysis of 1HNMR data indicated that brown, green, green-brown, red and red-brown coloured IMP samples were chemically distinct from each other, and showed two separate clusters for northern and southern states propolis samples. HPLC analysis confirmed phenethyl caffeate was most common and abundant compound in IMP samples among studied compounds.

In conclusion, this study may be helpful for defining quality of IMP as a raw material, and also in finished food and health care products.

Honey May Help Treat Diarrhea

Role of Honey in Topical and Systemic Bacterial Infections

J Altern Complement Med. 2017 Aug 24

BACKGROUND:

The development of bacterial resistance to antibiotics has made it more difficult and expensive to treat infections. Honey is getting worldwide attention as a topical therapeutic agent for wound infections and potential future candidate for systemic infections.

OBJECTIVES:

The purpose of this review was to summarise different antibacterial bio-active compounds in honey, their synergistic interaction and their clinical implications in topical and systemic infections. In addition, contemporary testing methods for evaluating peroxide and non-peroxide antibacterial activity of honey were also critically appraised.

DESIGN:

MEDLINE, EMBASE, Cochrane Library, Pub Med, reference lists and databases were used to review the literature.

RESULTS:

Honey contains several unique antibacterial components. These components are believed to act on diverse bacterial targets, are broad spectrum, operate synergistically, prevent biofilm formation, and decrease production of virulence factors. Moreover, honey has the ability to block bacterial communication (quorum sensing), and therefore, it is unlikely that bacteria develop resistance against honey. Bacterial resistance against honey has not been documented so far. Unlike conventional antibiotics, honey only targets pathogenic bacteria without disturbing the growth of normal gastrointestinal flora when taken orally. It also contains prebiotics, probiotics, and zinc and enhances the growth of beneficial gut flora. The presence of such plethora of antibacterial properties in one product makes it a promising candidate not only in wound infections but also in systemic and particularly for gastrointestinal infections. Agar diffusion assay, being used for evaluating antibacterial activity of honey, is not the most appropriate and sensitive assay as it only detects non-peroxide activity when present at a higher level. Therefore, there is a need to develop more sensitive techniques that may be capable of detecting and evaluating different important components in honey as well as their synergistic interaction.

CONCLUSIONS:

Keeping in view the current guidelines for treatment of diarrhea, honey is considered one of the potential candidates for treatment of diarrhea because it contains a natural combination of probiotics, prebiotics, and zinc. Therefore, it would be worthwhile if such a combination is tested in RCTs for treatment of diarrhea.

Review of the Many Medicinal Uses of Honey

Honey: Single food stuff comprises many drugs

Saudi Journal of Biological Sciences
Available online 16 August 2017

Honey is a natural food item produced by honey bees. Ancient civilizations considered honey as a God gifted prestigious product. Therefore, a huge literature is available regarding honey importance in almost all religions.

Physically, honey is a viscous and jelly material having no specific color. Chemically, honey is a complex blend of many organic and inorganic compounds such as sugars, proteins, organic acids, pigments, minerals, and many other elements. Honey use as a therapeutic agent is as old as human civilization itself. Prior to the appearance of present day drugs, honey was conventionally used for treating many diseases.

At this instant, the modern research has proven the medicinal importance of honey. It has broad spectrum antibiotic, anti-viral and anti-fungal activities. Honey prevents and kills microbes through different mechanism such as elevated pH and enzyme activities. Till now, no synthetic compound that works as anti-bacterial, anti-viral and anti-fungal drugs has been reported in honey yet it works against bacteria, viruses and fungi while no anti-protozoal activity has been reported.

Potent anti-oxidant, anti-inflammatory and anti-cancerous activities of honey have been reported.

Honey is not only significant as anti-inflammatory drug that relieve inflammation but also protect liver by degenerative effects of synthetic anti-inflammatory drugs. This article reviews physico-chemical properties, traditional use of honey as medicine and mechanism of action of honey in the light of modern scientific medicinal knowledge.

Bee Venom May Help Treat Bovine Mastitis

Bee venom decreases LPS-induced inflammatory responses in bovine mammary epithelial cells

J Microbiol Biotechnol. 2017 Aug 17

The world dairy industry has long been challenged by bovine mastitis, an inflammatory disease, which causes economic loss due to decreased milk production and quality. Attempts have been made to prevent or treat this disease with multiple approaches, primarily through increased abuse of antibiotics, but effective natural solutions remain elusive. Bee venom (BV) contains a variety of peptides (e.g., melittin) and that shows multiple bioactivities including prevention of inflammation. Thus, in the current study, it was hypothesized that BV can reduce inflammation in bovine mammary epithelial cells (MAC-T).

To examine the hypothesis, cells were treated with LPS (1 μg/ml) to induce an inflammatory response and investigated anti-inflammatory effects of BV (2.5 and 5 μg/ml). The cellular mechanisms of BV against LPS-induced inflammation were also investigated. Results showed that BV can attenuate expression of an inflammatory protein, cyclooxygenase-2 (COX-2) and pro-inflammatory cytokines such as IL-6 and TNF-α. Activation of NF-κB, an inflammatory transcription factor was significantly downregulated by BV in cells treated with LPS through de-phosphorylation of ERK1/2. Also, pretreatment of cells with BV attenuated LPS-induced production of intracellular reactive oxygen species (e.g., superoxide anion).

These results support our hypothesis that BV can decrease LPS-induced inflammatory responses in bovine mammary epithelial cells through inhibition of oxidative stress, NF-κB, ERK1/2 and COX-2 signaling.

Australia and New Zealand Battle Over Manuka Honey


Kiwis launch big-money battle against Aussies over manuka honey

We’ve fought over the lamington and the pavlova, and now there’s a new food war brewing between Australia and New Zealand.

The Australian reported on what it called an “escalating and increasingly sour trans-Tasman trade dispute” over the naming rights on honey. New Zealand honey producers have applied to exclusively trademark the name ‘manuka’ in big markets including the US, the UK and China.

They argue that maunka is a Maori word and Australian producers are being opportunistic in trying to cash in on the success that Kiwi producers have had in marketing it. And it’s no little squabble – in Asia, manuka honey is in high demand because of its health properties and can sell for as much as $150 ($120) a kilo, according to The Australian‘s report...

There are several health benefits that honeybee products such as honey, propolis, and royal jelly claim toward various types of diseases in addition to being food.

SCOPE AND APPROACH:

In this paper, the effects of honey, propolis, and royal jelly on different metabolic diseases, cancers, and other diseases have been reviewed. The modes of actions of these products have also been illustrated for purposes of better understanding.

KEY FINDINGS AND CONCLUSIONS:

An overview of honey, propolis, and royal jelly and their biological potentials was highlighted. The potential health benefits of honey, such as microbial inhibition, wound healing, and its effects on other diseases, are described. Propolis has been reported to have various health benefits related to gastrointestinal disorders, allergies, and gynecological, oral, and dermatological problems. Royal jelly is well known for its protective effects on reproductive health, neurodegenerative disorders, wound healing, and aging. Nevertheless, the exact mechanisms of action of honey, propolis, and royal jelly on the abovementioned diseases and activities have not been not fully elucidated, and further research is warranted to explain their exact contributions.

Royal Jelly Boosts Wound Healing


The Royal Jelly Of Bees Is Great At Healing Wounds, And Now We Know Why

By Robin Andrews

When it comes to healing wounds, the things that always sound the most appropriate – and effective – always have fairly technical-sounding names. The US National Institutes for Health (NIH) cite a good few, including “collagen, silicon, chitosan, and hyaluronic acid” wound dressing polymers. They all sound rather sciencey, and are therefore probably quite good.

The technicality of the name of a wound-healing material, however, is not a good indicator of said effectiveness. This is fortunate, as the rather silly-sounding “royal jelly” is also pretty remarkable at healing wounds too, according to a new study in Scientific Reports...

Korean Acacia Honey Shows Anti-H. pylori Activity

Isolation of Abscisic Acid from Korean Acacia Honey with Anti-Helicobacter pylori Activity
Abstract

Pharmacogn Mag. 2017 Jul;13(Suppl 2):S170-S173

BACKGROUND:

Helicobacter pylori (H. pylori) is linked to the development of the majority of peptic ulcers and some types of gastric cancers, and its antibiotic resistance is currently found worldwide.

OBJECTIVE:

This study is aimed at evaluating the anti-H. pylori activity of Korean acacia honey and isolating the related active components using organic solvents.

MATERIAL AND METHODS:

The crude acacia honey was extracted with n-hexane, dichloromethane, ethyl acetate (EtOAc), and n-butanol. The EtOAc extract was subjected to octadecyl-silica chromatography. The extracts and fractions were then examined for anti-H. pylori activity using the agar well diffusion method. The antimicrobial activity of abscisic acid against H. pylori was investigated by determining the minimum inhibitory concentrations (MICs), minimum bactericidal concentrations (MBCs), and by performing a time-kill assay.

RESULTS:

Abscisic acid related to the botanical origins of acacia honey from Korea has been analyzed using ultra-performance liquid chromatography. The MICs and MBCs of abscisic acid were 2.7 ± 1.3 and 6.9 ± 1.9 μg/mL, respectively. The bactericidal activity of abscisic acid (at 10.8 μg/mL corresponding to 4 × MIC) killed the organism within 36-72 h. These results suggest that abscisic acid isolated from Korean acacia honey has antibacterial activity against H. pylori.

CONCLUSION:

Abscisic acid isolated from Korean acacia honey can be therapeutic and may be further exploited as a potential lead candidate for the development of treatments for H. pylori-induced infections.

SUMMARY:

The crude acacia honey was extracted with n-hexane, dichloromethane, EtOAc, and n-butanolThe EtOAc extract yielded eight fractions and four subfractions were subsequently obtained chromatographicallyAbscisic acid was isolated from one subfraction. All the solvent extracts and fractions showed antibacterial activity against H. pyloriAbscisic acid exhibited antibacterial activity against H. pylori.
