the present study was aimed to examine the association of bovine follicular stimulating hormone gene polymorphism with sperm quality traits including sperm volume (sv), sperm concentration (spco), total sperm (ts), fresh sperm motility (fsm), total fresh motile sperm (tfms), post thaw sperm motility (ptsm), total post thaw motile sperm (tptms), number of produced payout (npp), number of fresh m...

objective: adiponectin and its receptors (adipor1 and adipor2), known as adiponectin system, have some proven roles in the fat and glucose metabolisms. several studies have shown that adiponectin can be considered as a candidate in linking metabolism to testicular function. in this regard, we evaluated the correlation between sperm mrna abundance of adiponectin and its receptors, with sperm mot...

Motility could be an important adaptation of heterotrophic bacteria and archaea, and it may have ecological and biogeochemical implications. However, the limited observations so far show that only a small fraction (≤10%) of bacteria is motile. We report a systematic 10 mo long field study off the coast of La Jolla, California, as well as a mesocosm study to examine bacterial motility and its re...

The FertDish features a clinically applicable sperm processing format, and enables high recovery of motile with DNA quality.

Nonmotile primary cilia are recognized as important sensory organelles during development and normal biological functioning. For example, recent work demonstrates that transcriptional regulators of the sonic hedgehog signaling pathway localize to primary cilia and participate in sensing and transducing signals regarding the cellular environment. In contrast, motile cilia are traditionally viewe...

AIM To study whether additional measurements of motility characteristics of spermatozoa by computer assisted semen analysis (CASA) were more sensitive indicators of reduced semen quality than estimates of percentages of motile, rapid or progressive cells. METHODS Intermittent scrotal insulation was applied to 6 rams for 16 h per day for 21 days or to 2 of these for 12 h per day for 28 days in...

The (( Intermediate scattering function )t I(K, t ) of light scattered by motile bacteria is shown to be I(K, t ) = rn sin KVt jo T v T Ps(V) dV, (1) where Ps(V) is the distribution of swimming speeds of the bacteria. ~cattercd spectra from motile E, Coli Klz bacteria have been investigated by laser light intensity correlation spectroscopy. [Z(K, t ) ] z is obtained from the data and its angula...
