Background: Denatonium benzoate (DB) has been shown to influence ongoing ingestive behavior and gut peptide secretion. Objective: We studied how the intragastric administration of DB affects interdig...
Aging is associated with a decrease in appetite and a slowing of gastric emptying. The gastrointestinal hormones cholecystokinin (CCK), glucagon-like peptide 1 (GLP-1), and peptide YY (PYY) may med...
The major objective of the present study was to characterize the effects of oxidants generated b xanthine (X) plus xanthine oxidase (XO) on isolated rat ileum motility. The effects of three concentrat...
Oral mucosal tissue can serve as a long-term fluoride reservoir following topical application and retain a small amount of fluoride in oral environment for prevention of dental caries. The aim of this...
H. pylori is a gram-negative bacterium associated with gastric inflammation and peptic ulcer and considered a risk factor for gastric cancer in its natural habitat. However, the energy metabolism of...
Current evaluation of male fertility, routinely estimated by sperm count, motility, and morphology, provides only crude information about the fertility state of individuals. Both flow and image cyto...
The automated analysis of sperm motion endpoints is potentially useful in identifying male reproductive toxicants and ultimately in predicting fertility in humans. The present study was designed to ...
Tumor necrosis factor (TNF alpha) is present in elevated levels in peritoneal fluid from infertile women with endometriosis. The effect of TNF alpha on human sperm motility in vitro was evaluated ...
A sperm motility inhibitor from human seminal plasma was purified and characterized. The purification procedure includes dialysis, ion exchange chromatography on SP-Sephadex C-25 and adsorption chro...
High-speed videomicrography was used to assess simultaneously the morphology and motility of seminal spermatozoa from 10 fertile donors and 10 patients being evaluated for infertility. In both don...
Human spermatozoa treated with 0.05% Triton X-100 to remove the cell membranes became immotile but flagellar movement was reinitiated by addition of 0.06 to 1 mM adenosine triphosphate (ATP). The pe...
Quantitative methods for the determination of the concentration, percent motility and swimming speed of human and animal spermatozoa can assist in the objective analysis of sperm and semen quality. ...
The number of bovine spermatozoa separated in a swim-up procedure was quantified using an electronic cell counter. In an initial test of the swim-up procedure, non-frozen sperm samples with differen...
The conventional sperm characteristics of density (millions per milliliter) and motility, scored in a semi-subjective way, were correlated with results of an on-going in vitro fertilization and em...
The effectiveness of several glass coating agents in preventing sperm adherence to glass surfaces for both intact and demembranated human spermatozoa was investigated. These agents included bovine s...
