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.

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,

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."

Free Amino Acids Profile of Polish and Slovak Honeys

Free amino acids profile of Polish and Slovak honeys based on LC–MS/MS method without the prior derivatisation

Journal of Food Science and Technology, pp 1–8

LC–MS/MS method was applied for determination of free amino acids in honey without derivatisation steps.

Twenty free amino acids including aspartic acid, asparagine, glutamic acid, glutamine, alanine, arginine, glycine, leucine, histidine, hydroxyproline, isoleucine, lysine, methionine, phenylalanine, proline, serine, threonine, tryptophan, valine and ornithine were analyzed in thirty honey samples from Poland and Slovakia.

The analysis covered: acacia, lime, rape, multifloral and forest types of honey. Applied method was characterized to had good sensitivity with limit of detection ranged from 3.0 ng/cm3 for valine to 13.0 ng/cm3 for hydroxyproline.

Average content of proline (main amino acid component in honey) ranged from 151.46 μg/g (rape honey from Slovakia) to 389.66 μg/g for forest honey (honeydew honey) from Poland. In analyzed honeys large quantities of glutamine, glutamic acid, lysine, phenylalanine, asparagine, alanine, and valine were also found.
