Bovine embryos (day 5) were cultured to day 10 with or without 100 ng/mL PGF2α in medium supplemented with control; 100 nM Dex; 1,000 U/mL recombinant human leukemia inhibitory factor (rhLIF); or Dex+rhLIF. Although the rates to development to the blastocyst were not significantly different among groups, the hatching rate after additional culture with Dex +/or rhLIF was significantly higher in ...
Suckled Bos indicus Bos taurus cows were used to compare a Select Synch/CIDR + timed artificial insemination (AI) protocol (SSC) vs a modified Co-Synch/CIDR protocol (COS). Five groups of suckled Bos indicus Bos taurus cows were evaluated (n=659). Cows received GnRH and a CIDR on d 0. On d 7, SSC cows had their CIDR removed and received prostaglandin F2α (PGF2α), whereas COS cows had their ...
OBJECT Platelet isoprostane 8-ISO-prostaglandin F2α (8-iso-PGF2α), a proaggregating molecule, is believed to derive from nonenzymatic oxidation of arachidonic acid. We hypothesized that NADPH is implicated in isoprostane formation and platelet activation. METHODS AND RESULTS We studied 8-iso-PGF2α in platelets from 8 male patients with hereditary deficiency of gp91(phox), the catalytic subuni...
The aim of the study was to estimate association of the extent of angiographically proven coronary artery disease (CAD) with plasma 8-isoprostane F2 (8-iso-PGF2α) levels as a reliable marker of lipid peroxidation and serum activity of paraoxonase-1, which demonstrates the ability to protect against lipid oxidation. The study included 105 patients with angiographically documented CAD (CAD+) and ...
نگارنده دراین رساله اثرات محافظتی و مخرب مشتقات ایکوزانوئیدها بر روی مخاط معده را درهشت فصل بررسی نموده است . فصل اول به بافت شناسی و ساختمان عمومی اعضاء گوارشی پرداخته، فصل دوم شامل فیزیولوژی ترشح اسید معده (آناتومی سلولهای حاشیه ای، گیرنده سلولهای حاشیه ای و ...) و فصل سوم تاریخچه و ساختمان پروستا گلاندین ها (بیوسنتز پروستا گلاندین ها، متابولیسم پروستاگلاندین ها و ...) اشاره گردیده و در فصل چ...
The notion that oxidative stress plays a role in virtually every human disease and environmental exposure has become ingrained in everyday knowledge. However, mounting evidence regarding the lack of specificity of biomarkers traditionally used as indicators of oxidative stress in human disease and exposures now necessitates re-evaluation. To prioritize these re-evaluations, published literature...
Higher environmental temperature is one of the major factors responsible for reduced fertility in farm animals. Heat stress causes a great suppression in endometrial function [1] besides compromised follicular growth [2], embryonic function [3] and oocyte developmental potential [4]. Heat stress also increases the production of PGF2α in the endometrium, leading to the early regression of CL or ...
Luteinized unruptured follicle (LUF) syndrome is a recurrent anovulatory dysfunction that affects up to 23% of women with normal menstrual cycles and up to 73% with endometriosis. Mechanisms underlying the development of LUF syndrome in mares were studied to provide a potential model for human anovulation. The effect of extended increase in circulating LH achieved by administration of recombina...
In this study, we aimed to investigate reproductive performance in estrus-induced Zandi ewes treated with equine chorionic gonadotrophin (eCG) injection in combination with prostaglandin F2α (PGF2α)and gonadotrophin releasing hormone (GnRH) during non-breeding season. The estrous cycle was synchronized using controlled internal drug release (CIDR) for 12 days. The ewes were randomly assigned to...
زمینه : روش های مختلف جراحی و طبی جهت القای سقط مطرح شده است که یکی از آنها استفاده از پروستاگلاندین است. هدف : مطالعه به منظور مقایسه اثر آمپول پروستاگلاندین e2 و شیاف آن در القای سقط در سه ماهه دوم بارداری انجام شد. مواد و روش ها : این کارآزمایی بالینی یک سوکور در سال 1381 در بیمارستان کوثر قزوین بر روی 36 زن باردار که در سه ماهه دوم حاملگی به علت کاهش مایع آمنیوتیک یا مرگ داخل رحمی جنین ، کا...
