UNLABELLED Objectives : The aim of the present study was to evaluate protective effect of royal jelly on sperm parameters, testosterone level, and malondialdehyde (MDA) production in mice. MATERIALS AND METHODS Thirty-two adult male NMRI mice weighing 30±2 g were used. All the animals were divided into 4 groups. CONTROL GROUP received saline 0.1 ml/mouse/day orally for 30 days. Royal jelly ...
objective(s):paclitaxel is a potent chemotherapy agent with severe side effects, including allergic reactions, cardiovascular problems, complete hair loss, joint and muscle pain, which may limit its use and lower its efficiency. the cardioprotective effect of royal jelly was investigated on paclitaxel-induced damages. materials and methods:adult male wistar rats were divided into control and te...
Sperm limitation may be an important selective force influencing gamete traits such as egg size. The relatively inexpensive extracellular structures surrounding many marine invertebrate eggs might serve to enhance collision rates without the added cost of increasing the egg cell. However, despite decades of research, the effects of extracellular structures on fertilization have not been conclus...
Organisms with external fertilization are often sperm limited, and in echinoids, larger eggs have a higher probability of fertilization than smaller eggs. This difference is thought to be a result of the more frequent sperm-egg collisions experienced by larger targets. Here we report how two components of egg target size, the egg cell and jelly coat, contributed to fertilization success in a se...
BACKGROUND Royal jelly is a nutritious substance produced by the young nurse bees and contains significant amounts of proteins which are important for cell growth and proliferation. The aim of this study was to evaluate the effect of royal jelly as an alternative to fetal bovine serum (FBS) in cell culture using cell proliferation assays and live cell imaging. MATERIALS AND METHODS MRC-5 cell...

OBJECTIVE This study tested the hypothesis that a standardized dose of jelly beans could be used as an alternative sugar source to the 50-g glucose beverage to screen for gestational diabetes mellitus. STUDY DESIGN One hundred sixty pregnant women at 24 to 28 weeks' gestation were recruited for a prospective study to compare 2 sugar sources for serum glucose response, side effects, preference...
Five preparations used as analgesics or lubricants in surgical, obstetrical, gynecological, and investigative procedures were tested for their effect on the isolation of Chlamydia trachomatis. Three lignocaine preparations and a lubricating jelly containing 2% phenol were inhibitory to chlamydiae. In contrast, K-Y lubricating jelly was relatively nontoxic to chlamydiae. Since K-Y jelly also had...
In the first paper of this series, it was shown that gelatinization of starch was necessary to enhance jelly strength of fish meat jelly (Kamaboko), and that starch added in Kamaboko , though gelatinized, chiefly existed in the jelly as granules and partly dispersed into meat as amylose. In the present paper, amylose and amylopectin, the two components of starch , were isolated by an improved S...
Background. Royal jelly is a milky material secreted by the pharyngeal glands of young worker bees , which when fed as a sole nutrient to larvae causes the development of sexual mature queen bees. The unusual nature of this material has prompted different investigations into its biological/pharmacological/microbiological properties. As an part of the biological activity of royal jelly, an inves...
