Discussion of Dr. Bull's Paper.
A computerized system (CellSoft, CRYO Resources, Ltd.) was validated using video tapes of frozen-thawed bull spermatozoa diluted in filtered (0.2 micron) egg yolk-citrate extender (8 X 10(6) spermat...
Seven rhodamine-conjugated lectins (PNA, RCA I, SBA, Con A, WGA, UEA I, DBA) were used to study the distribution of glycoproteins in the testis and epididymis of immature, juvenile, and adult bulls....
In Vitro binding and some binding parameters of the glycosaminoglycan heparin to viable epididymal or ejaculated bull spermatozoa, ejaculated rabbit spermatozoa, and frozen-thawed rhesus monkey sper...
The effect of exogenous follicle stimulating hormone (FSH) on testicular function was studied in twenty 4-month-old Holstein bulls during two seasons (ten in late winter and ten in summer). Five mg ...
Ejaculates from normal and castrated bulls were evaluated for the presence of inhibin-like activity. Inhibin activity found in the seminal plasma of normal bulls became undetectable after castrati...
Clusterin from bull rete testis fluid (RTF), cauda epididymal fluid (CEF), and octyl-beta-D-glucopyranoside extract of cauda epididymal sperm (CES) was identified and characterized using monoclonal ...
We evaluated the effect on fertility of in vitro exposure of thawed frozen bull sperm to synthetic FertPlus peptide prior to artificial insemination (AI). The peptide represented a 60-amino acid s...
We evaluated the effects of in vitro exposure of sperm to synthetic FertPlus peptide, which represents a 60-amino acid sequence within rat prosaposin, using a microwell sperm-binding assay (SBA), ...
Artificial insemination using cryopreserved semen is a common management tool of the contemporary livestock producer. However, cryopreservation is detrimental to sperm function and fertility, kill...
The objective of this research was to investigate possible procedures for evaluating living bull sperm stained with Hoechst 33342 while in a simple medium and in commonly used complex egg yolk-glyce...
Anti-bull sperm monoclonal antibodies (mAbs), generated against intra-acrosomal and surface antigens, were evaluated for their functional significance. In experiment I, the influence of mAbs on the bo...
The overall objective of this series of experiments is to generate immunological markers that may elucidate bull sperm surface changes in vitro. Here we report the initial experiments of the study, ...
Proper handling of semen prior to computer-assisted sperm analysis (CASA) is critical if the analysis is to be representative of the fresh sample. The effects of diluting medium or dilution and ho...
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 ...
