objectives: royal jelly (rj), a secretion of both the hypopharyngeal and mandibular glands of nurse workers, is believed to play a central role in honeybee queen development. important component of royal jelly are proteins which form about 50% of the dry mass of rj. major royal jelly proteins (mrjps) are the dominant proteinaceous component of royal jelly and constitute about 82-90% of total pr...

Royal jelly is a milky-white colored secretion produced by the hypopharyngeal and mandibular glands located in the head of young worker honeybees to feed the larvae in the colony (Münstedt and von Georgi , 2003). If a queen bee is desired, a chosen larva will be provided a large quantity of royal jelly as its only food source, which induces rapid differentiated growth and morphology. Because of...

Background: Phenylhydrazine (PHZ) is used to induce experimental anemia in animal models. On the other hand royal jelly is known as antioxidant compound. Therefore, here in present study we aimed to evaluate the protective effect of royal jelly on PHZ-induced damages in testicular tissue and compare its impact with vitamin C. Materials and Methods: Eighteen mature male mice were randomly divide...

New approaches for treatment of infectious diseases in aquatic animals have important roles in aquaculture technology progress. In the present study, In vitro effects of different extracts of propolis, royal jelly and pollen obtained from beehives have been investigated on aquatic pathogenic bacterial isolates. The isolated bacteria identified on the basis of their biochemical properties and se...

Pseudomonas aeruginosa is a Gram-negative bacterium and causes respiratory infection especially in elderly patients. Royal jelly has been used worldwide as a traditional remedy and as a nutrient; however, the effect against P. aeruginosa is unclear. The aim of this study was to analyze antibacterial, antiadherent, and anti-inflammatory effects of royal jelly against P. aeruginosa. Wild-type str...

China is the largest royal jelly producer and exporter in the world, and high royal jelly-yielding strains have been bred in the country for approximately three decades. However, information on the molecular mechanism underlying high royal jelly production is scarce. Here, a cDNA microarray was used to screen and identify differentially expressed genes (DEGs) to obtain an overview on the change...
