Snow leopard（Panthera uncia）spermatozoa are sensitive to alkaline pH, but motility in vitro is not influenced by protein or energy supplements
Felid comparative biology sperm culture medium sperm function capacitation
2009/2/16
To better understand the biology of snow leopard spermatozoa and to facilitate developing assisted reproduction, a series of studies was conducted to: 1) identify the component(s) of complex cultu...
Effects of glucose and other energy substrates on the hyperactivated motility of macaque sperm and the zona pellucida-induced acrosome reaction
glucose hyperactivated motility macaque sperm
2009/2/13
Energy sources in sperm capacitation media have various effects on mammalian sperm and are required for stimulation of hyperactivated motility and/or acrosome reactions in some species. The presen...
A comparison of critical osmolality and hydraulic conductivity and its activation energy in fowl and bull spermatozoa
Water permeability plasma membrane flow cytometry
2009/2/10
Measurements were made of critical osmolality, the osmolality at which 50% of the cells are lysed, and of the permeation time, the time taken to lyse 50% of the cells in an osmotic solution lower ...
DNA-flow cytometry of defined stages of rat seminiferous epithelium: effects of 3 Gy of high-energy X-irradiation
testis Sertoli germ cell
2009/2/6
Testes of adult Sprague-Dawley rats were irradiated locally by 3 Gy of 4 MeV X-rays produced by a linear accelerator. This type and dose of radiation gives an even distribution through the testis an...
