La recherche présentée dans cet article est la suivante : le cadre formation à l’éthique, infirmières, bénéficiant d’une basée sur l’analys...

Aim: To evaluate the effect of exogenous platelet activating Factor on capacitation and acrosome reaction in the sperms of infertile subjects. Methods: Forty samples of semen were collected, twenty each from non-male factor infertile subjects (controls) and twenty from male factor infertile subjects (patients). The sperms were separated from seminal fluid by using Sydney IVF sperm gradient kit....

BACKGROUND Improvement of baboon sperm capacitation is necessary for achieving high in vitro fertilization (IVF) rates in baboons. In this study, we evaluated separate and combined effects of caffeine and dbcAMP on baboon sperm capacitation. METHODS Sixteen male baboons (n = 16) were electroejaculated. Each sperm sample was divided into two aliquots: one for chemical activation and the other ...

Despite an increase in rising powers providing security force assistance (SFA) to Africa, the expertise and capabilities made available by these countries remain insufficiently explored. What different solutions, if any, are brought forward? And how does their overall record fare against previous experiences across continent? By exploring Brazilian Chinese efforts Namibia as well Indian overtur...

The efficiency of sperm capacitation and of the acrosome reaction was studied in the teratospermic domestic cat to evaluate further the etiology of compromised zona pellucida penetration and oocyte fertilization. Specific objectives were to compare normospermic and teratospermic cat ejaculates for 1) the kinetics and timing of sperm capacitation in vitro as determined by an ionophore-induced ac...

In order to be able to fertilize oocytes, human sperm must undergo a series of morphological and structural alterations, known as capacitation. It has been shown that the production of endogenous sperm reactive oxygen species (ROS) plays a key role in causing cells to undergo a massive acrosome reaction (AR). Astaxanthin (Asta), a photo-protective red pigment belonging to the carotenoid family,...
