After NMS administration plasma adipokines levels were determined in fed and fasting monkeys. Four intact adult male monkeys were used in this study. 50 nmol of NMS was injected intravenously. Blood samples were collected individually 60 min before and 120 min after NMS administration at 15 min intervals. The plasma adipokines concentrations were d...

After refeeding, body mass can not be returned to the control value on refeeding 12 h, and it returned to control level on refeeding 7 days, but body fat mass can not be restored to the control level on refeeding 7 days. RMR and mass of liver decreased significantly in fasting groups, which c...

...It has been demonstrated leptin act as a critical metabolic cue linking adipose and the onset of puberty. In the present study, we first assessed the morphological changes in adipose tissue at pre-puberty and puberty onset stages of goats, and then determined the role of leptin to activate signaling pathways which modulate the expression of hypothalamic genes involved in reproduction and metabolism. We found that

Therefore, IGF1/BfoI and Lep/BcnI polymorphisms were examined by polymerase chain reaction- restriction fragment length polymorphism method. The single nucleotide polymorphism (SNP) in the regulatory region of the IGF1 gene was detected by amplification of the 294 bp region using specific primers and cleavage with the BfoI enzyme. Allele frequencies of A ...
