In sheep industry, pregnancy rate after artificial insemination (AI) declines due to the complex anatomy of the cervix in ewes, such that it might prevent effective intrauterine insemination. At estrus, cervical relaxation occurs to some degree in ewes, which is regulated by the changes in the levels of reproductive hormones. This study aimed to evaluate the effects of estradiol and intravenous...

The objective of the present work was to investigate the existence of an oxytocin (OT)-mediated autocrine/paracrine signaling upon small cell carcinoma of the lung (SCCL) cell growth. In that view, OT receptor (OTR) expression, concomitant with OT synthesis and secretion, was evidenced on three different SCCL cell lines (DMS79, H146, and H345) and related to the vasopressin (VP) system. Specifi...

IMPORTANCE Vitamin D supplementation in infancy is required to support healthy bone mineral accretion. A supplement of 400 IU of vitamin D per day is thought to support plasma 25-hydroxyvitamin D (25[OH]D) concentrations between 40 and 50 nmol/L; some advocate 75 to 150 nmol/L for bone health. OBJECTIVE To investigate the efficacy of different dosages of vitamin D in supporting 25(OH)D concen...

A comparative study of rabbit pyrogen test and human whole blood assay was performed on released preparations of human serum albumin. In addition, the samples were spiked with 5 IU/ml (in whole blood 0.5 IU/ml too) and 10 IU endotoxin/ml. The unspiked samples were negative in both assays. The human whole blood test resulted in the same level of security for the products as the rabbit pyrogen te...

introduction: vaccination with the major surface antigen of hepatitis b virus (hbsag) induces anti-hbs antibody production and level of 10 iu/l is considered protective. it has been shown that the level of anti-hbs antibody does wane after vaccination. the aim of this study was to evaluate the persistence of anti-hbs antibodies in healthy iranian children 10 years after primary vaccination. met...

Oxytocin (OT) and arginine vasopressin (AVP) are closely related nine amino acid neuropeptides primarily produced in the hypothalamus and released both in the peripheral and central nervous systems. For over 100 years, OT and AVP have been known for their roles in uterine contraction/milk letdown and blood vessel constriction, respectively. Over the past few decades, the roles of OT and AVP in ...

Abstract Introduction: Occurrence of cardiac arrhythmias and myocardial infarction are two main deleterious events that are caused by ischemia-reperfusion (IR) injury in the heart. Cardiac preconditioning represents the most potent method of rescuing heart tissue from undergoing irreversible ischemic damage. The aim of the present study was to evaluate oxytocin (OT) cardioprotective effect...
