    Abstract: Epididymal sperm maturation is the process through which sperm acquire the potential to fertilize the egg. For most mammals, studies report that this process is completed before the sperm enter the cauda region of the epididymis; however, in some bat species, such as the Mexican big-eared bat (Corynorhinus mexicanus), this does not occur, as the pr...

    Abstract: GGT initiates the degradation of both oxidized and reduced glutathione at the cell surface by cleaving the unique gamma glutamyl bond. The successive hydrolysis of oxidized or reduced CysGly by aminopeptidase or dipeptidase releases Gly, and cysteine/cysteine is recovered for intracellular synthesis of glutathione. In addition, GGT plays a major ph... Show More

    Abstract: In Chihuahuan Desert arid zone, particularly the states of Zacatecas and San Luis Potosi, Mexico, have been distinguished by its large mining activity, however, many of these mines are disuse, becoming potential refuges for various species of cave bats. Monitoring the potential roosts by Corynorhinus townsendii was made within the system of mines i... Show More

    Abstract: Studies in reproductive age mammals show that the increase in fat content is inversely related to sperm quality in response to a decrease in testosterone levels. In turn the decrease in androgen concentration is related to morphophysiological involution in the testis and epididymis. However, the bat Leptonycteris yerbabuenae increases the body fat ...
