The mite Varroa destructor Anderson & Trueman is a parasite of the honeybee Apis mellifera L. and represents a major threat for apiculture in the Western world. Reproduction takes place only inside bee brood cells that are invaded just before sealing; drone cells are preferred over worker cells, whereas queen cells are not normally invaded. Lower incidence of mites in queen cells is at least partly due to the deterrent activity of royal jelly. In this study, the repellent properties of royal jelly were investigated using a lab bioassay. Chemical analysis showed that octanoic acid is a major volatile component of royal jelly; by contrast, the concentration is much lower in drone and worker larval food. Bioassays, carried out under lab conditions, demonstrated that octanoic acid is repellent to the mite. Field studies in bee colonies confirmed that the compound may interfere with the process of cell invasion by the mite.

Ethanolic extracts of seasonally collected natural bee products (honey, propolis, royal jelly (RJ), and bee venom (BV)) were tested for their potential as antimicrobial agents against antibiotic-resistant bacteria and fungi. These extracts exhibited various inhibitory effects on antibiotic-resistant bacteria (Streptococcus pneumoniae, Staphylococcus aureus, MRSA, Salmonella typhimurium, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Proteus vulgaris, and Haemophilus influenzae) and fungi (Aspergillus brasiliensis and Candida albicans), with the exception of S. pneumonia, which was not inhibited by honey and RJ extracts, and P.

Objectives: Nonsteroidal anti-inflammatory drugs (NSAIDs) are used for pain and inflammation relief. Our study aimed to explore the ulcerogenic effect of long-term diclofenac and celecoxib administration on male albino stomachs, focusing on the possible gastroprotective effect of royal jelly administration.
Methods: Five equal groups of 50 male albino rats.

Royal jelly (RJ), a natural product secreted by honeybees, is widely used in topical skincare products to help maintain cutaneous homeostasis. Despite its popularity, the mechanism through which RJ exerts its effects on the skin has not been fully elucidated. This study aimed to explore the impact of RJ on the proliferative ability and senescence of human primary epidermal keratinocytes (HPEKs).
