Female remating rate dictates the level of sperm competition in a population, and extensive research has focused on how sperm competition generates selection on male ejaculate allocation. Yet the way ejaculate allocation strategies in turn generate selection on female remating rates, which ultimately influence levels of sperm competition, has received much less consideration despite increasing ...

INTRODUCTION Male infertility factor is defined if the total number of motile spermatozoa (TMSC) < 20 × 10(6)/ejaculated, and unexplained infertility if spermiogram is normal with normal female factor. THE AIM of this study was to determine the predictive value of TMSC for spontaneous pregnancy (ST) and pregnancy after treatment with intrauterine insemination (IUI) in couples with male factor...

BACKGROUND Prostate cancer (PCa) diagnosis requires improvement with the aid of more accurate biomarkers. Postejaculate urethral washings (PEUW) could be a physiological equivalent to urine obtained following rectal prostatic massage, the current basis for the prostate cancer antigen 3 (PCA3) test. The aim of this study was to investigate if PEUW contained prostate-based material, evidenced by ...

ESP students are usually suggested to master general and academic word lists such as Wests’ (1953) General Service List (GSL) and Coxhead’s (2000) Academic Word List (AWL) to be able to read their academic texts. However, it seems that university students may not need to learn all the words in the two lists as some words in the lists are of less frequency in academic texts. Moreover, there are ...

background: equine piroplasmosis is caused by two haemoprotozoan parasites: babesia caballi and theileria equi . negative economic impact on international trade has been associated to endemic sites. this is the reason why carrier detection requires reliable diagnostic methods. various diagnostic modalities can be used alone or in combination including pcr. however, genetic variation of commonly...

Objective(s): In this study, the neutralizing abilities of the equine and the recently introduced camelid antivenoms on the hemodynamic parameters (inotropism, chronotropism, and arrhythmogenicity) were assessed following envenomation by Hemiscorpius lepturus venom in rats. Materials and Methods: At first, the electrophoretic profiles of...

It is generally believed that variation in sperm phenotype within a single ejaculate has no consequences for offspring performance, because sperm phenotypes are thought not to reflect sperm genotypes. We show that variation in individual sperm function within an ejaculate affects the performance of the resulting offspring in the Atlantic salmon Salmo salar. We experimentally manipulated the tim...

Most studies regarding the marrow-derived equine mesenchymal stem cells (MSCs) have mainly focusedon the cell transplantation without considering the capacity of differentiation and in vitro requirements of thecells. These concerns were investigated in the present study. Equine MSCs were isolated from the sternalmarrow aspirates and expanded through two successive subcultures. Passage-2 equine ...
