background: bleomycin (bl) is a glycopeptide antibiotic obtained from the bacterium streptomyces verticillus which is routinely used for treatment of human cancers. royal jelly (rj) is a production from the hypo pharyngeal, mandibular and post cerebral glands of nurse bees. rj consists of 66% water, 15% sugars, 5% lipids, and 13% proteins, essential amino acids and vitamins. objective: the aim ...

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...

The jelly secreted by the oviduct of Rana pipiens has been analyzed histochemically and biochemically. Histochemical techniques show that the jelly contains neutral carbohydrates and a protein moiety. Colorimetric estimation reveals that the jelly contains protein and also appreciable quantities of hexose and hexosamine. Sialic acid is present. Chromatographic methods were employed to identify ...

Sinking of gelatinous zooplankton biomass is an important component of the biological pump removing carbon from the upper ocean. The export efficiency, e.g., how much biomass reaches the ocean interior sequestering carbon, is poorly known because of the absence of reliable sinking speed data. We measured sinking rates of gelatinous particulate organic matter (jelly-POM) from different species o...

the aim of this study was to compare the effects of using different levels of royal jelly in semen extender on viatal characteristics of goat sperm after freezing. semen was collected from four adult bucks twice a week and samples pooled together. sperm samples (six repeats) containing royal jelly in four levels (0.5, 1, 1.5 and 2%) had been frozen. after semen samples freezing – were thawed an...
