BACKGROUND In order to investigate whether gonadotrophin-releasing hormone (GnRH) antagonists exert a significant effect on steroid secretion in vivo compared with GnRH agonists, concentrations of sex steroid hormones (oestradiol, progesterone and testosterone) were studied in follicular fluid from women undergoing ovarian stimulation and treated with either GnRH agonist or antagonist. In addit...

This study aims to the process of fabricating and characterization nanofibers based on cellulose acetate polymer filled with ceftriaxone ibuprofen using electrospinning method as a model for targeted drug delivery system. Cellulose has been successfully fabricated into ibuprofen. The resulting have an average diameter in range 412.5 – 558.5 nm under conditions process, namely 22 kV voltage, 15 ...

Acetate, an important metabolite in most species, has a unique place in ruminant metabolism. As the major product of ruminal and caecal fermentation, acetate provides much of the energy requirements of ruminant tissues. Little information is available, however, on the overall utilization of acetate in sheep. Intravenous-acetate tolerance tests in sheep (Jarrett, Potter & Filsell, 1952; Pugh & S...

the purpose of this study was to investigate the hypothesis weather the combination of lead acetate and deltamethrin can enhance avian toxic effects produced by lead exposure only. overall, 48 japanese quails, coturnix coturnix japonica (15 day old) were randomly divided into 4 experimental groups of 12 birds each and sex ratio of 1:1. experimental groups consisted of control japanese quails, b...

effects of sodium salt solutions on physicochemical and sensory characteristics of refrigerated persian sturgeon (acipenser persicus) fillets during 12 days of storage were investigated. fillets were dipped in solutions (2.5% w/v) of sodium acetate (sa), sodium lactate (sl), sodium citrate (sc) and distilled water (as control) for 10 minutes and then packaged. an assessment of tbars, ffa, ph, h...
