Am J Physiol Cell Physiol 283: C1033–C1044, 2002. First published May 22, 2002; 10.1152/ ajpcell.00493.2001.—This study focused on the role of sodium-bicarbonate cotransporter (NBC1) in cAMP-stimulated ion tran...

Aim: Vasectomy is performed in deer for population control, maintain pedigreed animals and prevent inbreeding. Conventional procedure of vasectomy required a long-term anesthesia and longer duration of hospitalization, which often result in stress, morbidity and mortality. A study was conducted to capture, neuter and release the deer with minimal hospitalization and stress by adopting three fin...

Our laboratory has previously shown that the vacuolar H(+)-ATPase, located in a subpopulation of specialized cells establishes a luminal acidic environment in the epididymis and proximal part of the vas deferens (Breton S, Smith PJS, Lui B, and Brown D. Nat Med 2: 470-472, 1996). Low luminal pH is critical for sperm maturation and maintenance of sperm in a quiescent state during storage in thes...

KONDO, S., KAGAYA, M., TASHIMA, Y. and MORITA, T. The Quantitative Difference in Adrenergic Alpha-1, Alpha-2 and Beta Receptors between the Prostatic and Epididymal Ends of Dog Vas Deferens. Tohoku J. Exp. Med., 1992, 167 (2), 167-169 In order to study the regional differences in the distribution of adrenergic receptors of the vas deferens, we measured the amounts of adrenergic a-1, a-2 and R r...

This study was undertaken to explore the spinal cord segments controlling the canine and human vas deferens and differentiation of the mammalian sympathetic pathways to the vas deferens. Thoracolumbar white communicating rami (WCR) were electrically stimulated in the dogs. Stimulation of the 1st, 2nd, 3rd, and 4th lumbar WCR elicited an elevation of intraluminal pressure of the vas deferens in ...

The goal of this study was to test for expression of HCO3 (-) exchangers SLC26A3 and SLC26A6 in primary cultures of porcine vas deferens epithelial cells (1°PVD) and native porcine vas deferens. Quantitative RT-PCR revealed that mRNA coding for SLC26A6 was six times more abundant than mRNA coding for SLC26A3 in 1°PVD cells. Western blot analyses combined with surface biotinylation of 1°PVD demo...

Background and purpose: Cannabis is the source of at least seventy phytocannabinoids. The pharmacology of most of these has been little investigated, three notable exceptions being D9-tetrahydrocannabinol, cannabidiol and D9-tetrahydrocannabivarin. This investigation addressed the question of whether the little-studied phytocannabinoid, cannabigerol, can activate or block any G protein-coupled ...

STUDY QUESTION Do the luminal fluids of the epididymis and the vas deferens contribute to sperm chromatin fragmentation (SCF) in mice? SUMMARY ANSWER The luminal fluids of both organs are required for activating SCF in mice, but the vas deferens luminal fluid does this more efficiently than that of the epididymis. WHAT IS KNOWN ALREADY Mice sperm have the ability to degrade their DNA in an ...

background: precious fruits like jambul are neglected and wasted while environmental pollutants like lead intake remain overlooked. objective: the aim of this study was to investigate the effects of the jambul pulp extract on lead detrimental effects in pseudostratified epithelium and the stereocilia of mice epididymis and vas deferens. materials and methods: thirty young males mice (mus muscul...

A 10-year-old boy with cystic fibrosis (CF) (DeltaF508/G551D mutation) underwent an uneventful elective interval laparoscopic appendectomy. During routine laparoscopic inspection of the abdomen and groins, congenital bilateral absence of the vas deferens was noted. Pictures of the patient's internal inguinal ring noted at time of laparoscopy are presented and compared with a similar-aged patien...
