The permeability of rye leaf protoplasts to glycerol was determined using 1,3-14C glycerol and liquid scintillation spectrometry. Estimates were 1.0×10−8 m s−1 at 0°C and 4.1×10−8 m s−1 at 22 and 31°C. The activation energy for glycerol p

Effect of n-3 fatty acids and α-tocopherol on post-thaw parameters and fatty acid composition of bovine sperm

Autor: Armin Towhidi, J. E. Parks

Publikováno v: Journal of assisted reproduction and genetics. 29(10)

This study was designed to determine the combined effects of adding source of n-3 fatty acids (FA) and α-tocopherol (vitamin E, VE) to semen extender on freezability and FA composition of Brown Swiss bull sperm.Semen samples were collected from 6 Br

In vitro production of haploid germ cells from fresh or frozen-thawed testicular cells of neonatal bulls

Autor: D R, Lee, M T, Kaproth, J E, Parks

Publikováno v: Biology of reproduction. 65(3)

Improved methods for culturing spermatogenic cells will facilitate the study of spermatogenesis, treatment of male factor infertility, and genetic modification of the male germ line. The objective of this study was to develop a procedure for achievin

Effects of cryopreservation procedures on the cytology and fertilization rate of in vitro-matured bovine oocytes

Autor: K M, Saunders, J E, Parks

Publikováno v: Biology of reproduction. 61(1)

The survival and developmental capacity of bovine oocytes after cryopreservation are greatly impaired, possibly due to organelle damage caused by freezing procedures. Distributions of chromosomes, microtubules, and microfilaments in bovine oocytes ma

Thermotolerance of IVM-derived bovine oocytes and embryos after short-term heat shock

Autor: J C, Ju, J E, Parks, X, Yang

Publikováno v: Molecular reproduction and development. 53(3)

A series of experiments were designed to study the effect of elevated temperatures on developmental competence of bovine oocytes and embryos produced in vitro. In experiment 1, the effect of heat shock (HS) by a mild elevated temperature (40.5 degree
