Estrogen and LH Dynamics During the Follicular Phase of the Estrous Cycle in the Asian Elephant
Pituitary and corpus luteum hormone patterns throughout the elephant estrous cycle have been well characterized. By contrast, analysis of follicular maturation by measurement of circulating estrogens has been uninformative. This study tested the ability of a urinary estradiol-3-glucuronide radioimmunoassay to noninvasively assess follicular development during the nonluteal phase of the elephant...
متن کاملEffects of Rams and Luteal or Follicular Phase Ewes on Preovulatory LH Surge Characteristics in Ewes*
This study aimed to investigate whether the preovulatory LH surge mechanism is involved in sheep-to-sheep interaction for oestrous synchronisation. For that purpose, anoestrous ewes were inserted with intravaginal progestagen sponges for 13 days to induce ovulation. Upon sponge withdrawal, they were introduced either to 4 rams (n = 6, ram group), or to 4 ewes which were in follicular period (n ...
متن کاملDoes exogenous progesterone and oestradiol treatment from the mid-luteal phase induce follicular cysts in goats?
The purpose of the present study was to investigate the effects of exogenous ovarian steroid treatment, which is known to induce follicular cyst experimentally in cows, on ovarian activity in goats. Eleven female Shiba goats with the length of the normal oestrous cycle (approximately 21 days) received subcutaneously either 1 ml of ethanol (control group, n=4) or 4 mg of progesterone and 2mg of ...
متن کاملconditional copula-garch methods for value at risk of portfolio: the case of tehran stock exchange market
ارزش در معرض ریسک یکی از مهمترین معیارهای اندازه گیری ریسک در بنگاه های اقتصادی می باشد. برآورد دقیق ارزش در معرض ریسک موضوع بسیارمهمی می باشد و انحراف از آن می تواند موجب ورشکستگی و یا عدم تخصیص بهینه منابع یک بنگاه گردد. هدف اصلی این مطالعه بررسی کارایی روش copula-garch شرطی در برآورد ارزش در معرض ریسک پرتفویی متشکل از دو سهام می باشد و ارزش در معرض ریسک بدست آمده با روشهای سنتی برآورد ارزش د...
O-26: Effects of Recombinant-LH Supplementation on The Proteomic Profile of Follicular Fluid from Poor Responder Patients: Focus on Follicular Growth Factors and Oocyte Maturity Markers
Background Poor and fragmentary data was available regarding the effects of recombinant-LH (r-LH) in in-vitro granulosa and theca cells of human origin. No data was available from in vivo studies regarding the effects of r-LH supplementation on SCF,EGF,ERK-1/2 and AKT-1 pathways in the follicular fluid of older-poor-responder women undergoing IVF cycle. Evidence from in-vitro and animal studies...
