By using enzyme immunoassay techniques we have quantified the ovarian ecdysteroids during the 7-day cycle of olicyte maturation in Blattella germanica. Immunoreactive ecdysteroid levels were low on days O-2, increased to higher values on days 3-6, and peaked on day 7 (about 5 ng of 20-hydroxyecdysone equivalents per pair of ovaries). The predominant non-conjugated ovarian ecdysteroid detected b...

Adult Channa punctatus murrels of both sexes (60-80 g) were collected locally from Ramgarh Lake during the second week of every month (10 individuals of each sex/month) throughout the year. Blood samples were collected and analyzed for serum calcium and phosphate levels by the methods of Trinder (1960) and Fiske and Subbarow (1925), respectively. Gonads were fixed to judge the state of maturati...

During puberty, rapid, complex hormonal, physical and cognitive changes occur that affect body image eating behavior. The aim of this cross-sectional study, a secondary analysis data from the Greek Healthy Growth Study, was to explore associations disordered behaviors in 1206 10–12-year-old girls during pubertal maturation, with serum leptin adiponectin levels, according mass index (BMI). Eatin...

  Background & Aim: Considering that antioxidants are known as effective free radicals scavenger, it may be able to improve the in vitro oocyte maturation and the fetal quality. This study was designed to determine the effect of Gundelia tournefortii leaves (GTE) hydro-alcoholic extract as a source of antioxidant on in vitro oocyte maturation. Experimental: Germinal vasicle (GV) were...

fats and oils are made of triglycerides. the fatty acids are the main constituents of triglycerides. there are minor components present in the oils and fats that are of great importance in human health, namely tocopherols and phenolic compounds that exhibit antioxidant activities. the concentrations of these compounds vary during ripening and maturation of olives. the object of the present stud...

introduction: in vitro maturation and development of immature oocytes, as an artificial reproduction technique, is useful especially in women who are affected by cancer and polycystic ovary syndrome. despite using many types of in vitro media, an appropriate environment has not been reported yet. present study was designed to assess the effect of heated human follicular fluid (hhff), which is s...

background: due to lack of detailed standards of sexual maturity in individuals with intellectual, sensory and motor disability in iran and the importance of timing of onset of puberty in these individuals, a study is necessary. by knowing the onset of puberty, physiologic and behavioral changes can be traced in these people, as well as the potential impact of the puberty on the underlying dise...

background: dendritic cells (dcs) are professional antigen presenting cells that have an important role in the initiation of immune response. the use of maturation factors in dendritic cell differentiation provides a promising approach in immunotherapy. objective: in this study, we compared tumor necrosis factor-α, polyribocytidylic acid, lipopolysacharide and cpg oligonucleotides in inducing d...

PURPOSE Histomorphometry and microhardness measurements were performed after Ti6AI4V implantation in cancellous and cortical bone of healthy and ovariectomized animals to determine characterization of the bone-biomaterial interface in osteopenic bone. MATERIALS AND METHODS Nine ovariectomized and 9 sham-aged rats were used. Four months later, nails were implanted in the distal femurs, and the...

PURPOSE To examine 1-year changes in insulin dynamics in overweight Hispanic children at high-risk of type 2 diabetes as a function of body composition and pubertal transition. EXPERIMENTAL DESIGN Longitudinal changes in insulin dynamics, body composition and maturation were determined in 132 Hispanic children (70 boys/62 girls; aged 10.9 +/- 1.8 years). METHODS Body composition was determi...
