Background
During the post‐testicular maturation that occurs in the epididymis, spermatozoa need to face biochemical and morphological changes that may make them vulnerable to oxidative damage. During spermatogenesis and the epididymal maturation, the spermatozoon acquires antioxidant enzymes needed to face possible increases of reactive oxygen species (ROS) produced by its own aerobic metabolism...
From the beginning, a key element of the Internet's success has been collaboration between its engineers, researchers, network operators, vendors, and service providers. Although the region of Latin America and the Caribbean is one of the fastest growing and most dynamic Internet markets in the world, with roughly a tenth of the Internet's current users, until recently, it didn't have an established...
After capacitation, mammalian spermatozoa accomplish the acrosome reaction (AR), a well-controlled exocytosis process crucial to fertilize mature oocytes that involves several protein kinases such as protein kinase A (PKA), C (PKC), and tyrosine kinase (PTK). Reactive oxygen species (ROS) are involved in both bovine sperm capacitation and AR. Lactate dehydrogenase C4 (LDH-C4) was associated with bovine...
