The present study investigated serum cortisol in response to postpartum ovarian resumption and luteal function. Postpartum ovarian resumption was detected based on a rise in progesterone (P4) concentrations during three weeks after calving. Twenty two Holstein cows in a semi-closed dairy farm in Qena city, Egypt were used. The study was carried out from late March to early June; the period char...

Oocyte meiotic resumption is triggered by the ovulatory gonadotropin surge; in cattle, angiotensin II (AngII) and prostaglandins (PG) are key mediators of this gonadotropin-induced event. Here, we tested the hypothesis that progesterone (P(4)) is also involved in oocyte meiotic resumption induced by the gonadotropin surge. In Experiment I, P(4) induced nuclear maturation in a dose-dependent man...

Nowadays, nearly every mainstram programming language includes an exception handling mechanism. Basically, the variety of these mechanisms can be devided in two groups according to their handling models: Mechanisms which support exception termination and those which support resumption. Even though resumption was still an attractive alternative to termination for the first exception handling mec...

BACKGROUND Prior investigation of out-of-hospital cardiac arrest has raised the concern that ventricular fibrillation (VF) recurrence may be triggered by chest compression (CC) resumption. We investigated predictors of VF recurrence after defibrillation, including timing of CC resumption. METHODS AND RESULTS Patients with witnessed out-of-hospital cardiac arrest and initial rhythm of VF from ...

Two types of resumption are argued for in the literature: (i) base-generated resumption and (ii) resumption as movement (Aoun et al. 2001; Boeckx 2003). The latter is analyzed as involving stranding. A DP merges in its base position with a resumptive element adjoined to it. Movement targets the DP, while the resumptive element is left behind – or stranded. This article presents evidence from Co...

P450 aromatase is a key enzyme in steroidogenesis involved in the conversion of testosterone into 17β-estradiol. We investigated the localization and the expression of P450 aromatase in Podarcis sicula testes during the different phases of the reproductive cycle: summer stasis (July-August), early autumnal resumption (September), middle autumnal resumption (October-November), winter stasis (Dec...

introduction: in this study in vitro maturation, resumption of meiosis and development of immature mouse oocytes in the presence of cysteamine was evaluated. meterial and methods: immature oocytes recovered from nmri mouse strain (4-6 weeks) were categorized in three experimental and one control group. the control included 345 immature oocytes which were matured in mem medium contain 5% fcs. in...

Fully grown mammalian oocytes resume meiosis as a consequence of rises in gonadotropin levels at the mid-cycle. The increase of cyclic adenosine 3',5'-monophosphate (cAMP) and the activation of protein kinase A (PKA), protein kinase C (PKC) and mitogen-activated protein kinase (MAPK) in cumulus cells are required for gonadotropins-induced meiotic resumption of oocytes. The various actions of cA...

Purpose: The aim of this study was evaluated the effect of β -mercaptoethanol on resumption of meiosis, In vivo maturation of immature mouse oocytes treated with DEHP and embryo development. Materials and Methods: NMRI mouse strain (4-6 weeks) were treated daily with 50,µI DEHP Group 1: 121 immature oocytes were matured in MEM-α medium contain FCS 5%, hCG 7.5 IU/ml, rFsH 100mIU/ml, Group 2: 12...
