(band) disrupts blood supply to the scrotum, causing it to die and eventually drop off. Sometimes, the testes are pushed up inside the body wall and the ring is applied below the testes to produce a "short scrotum." A short-scrotum ram produces testosterone, but not sperm, thus he'll...
Sheep and goats are often used for production of various reagents used in experimentation including red blood cells, sera and antibodies. Relief of pain is a scientific imperative for any species used in biomedical research (NRC, 2011). Recognition and relief of pain is required by the Animal ...
The presence of RNAs in sperm has long been a topic of intensive debate, largely due to the highly compact nature of DNA and the minimal amount of cytoplasmic remnant within the mature sperm. Testis-derived RNAs are continuously produced throughout the various stages of spermatogenesis. Compared ...
Third, the volume of blood infusion is limited; however, because sEVs can be concentrated during purification, their rejuvenating effect can be amplified. However, despite the promising and encouraging results, there is a long journey ahead from experimental studies to the clinical application of ...
Blood pressure (BP) monitoring in young chronic kidney disease (CKD) patients, especially those undergoing dialysis or post-transplant, is inadequately studied using ambulatory blood pressure monitoring (ABPM). This meta-analysis intends to calculate the incidence of white-coat hypertension (WCH) and...
Recent investigations into heterochronic parabiosis have unveiled robust rejuvenating effects of young blood on aged tissues. However, the specific rejuvenating mechanisms remain incompletely elucidated. Here we demonstrate that small extracellular vesic
The pseudo-penis has no blood vessels and does not carry sperm but instead appears to be favored by the females for pleasure and aids males in attracting females; males in colonies have larger pseudo-penises than males which live alone, suggesting male-male competition has also favored the ...
than half their time. Essentially the only reason males and females meet is to mate.The male contributes nothing but sperm to the raising of young, despite cubs taking up to 13 months to become self-sufficient hunters. The nest in which the mother raises the young is known as a ‘holt’...
Small membranous vesicles (25–75 nm in diameters) were purified from the ram cauda epididymal fluid by only high-speed centrifugation [29]. These vesicles according to SDS-PAGE protein pattern are specific and significantly differ from those of the seminal plasma, sperm extract and the caudal ...
