... + . Previous research has shown that when pH i is above 7.2–7.3, the dynein ATPase flagellar motors are activated, and the sperm become motile. It has been hypothesized that ocean acidification (OA), which decreases the pH of seawater, may have a narcotic effect on sea urchin sperm by impairing the ability...

...Anirudh Kulkarni; Irene Elices; Nicolas Escoubet; Léa-Laetitia Pontani; Alexis Michel Prevost; Romain Brette ABSTRACT We present a simple device to mechanically immobilize motile cells such as ciliates. It can be used in particular for intracellular electrophysiology and microinjection...

... acclimation of males reduced their fertilization probability (lower sperm velocity) when compared with cold-acclimated males, especially when the activation water temperature was also increased beyond the thermal optimum (resulting in a lower proportion of motile sperm with lower velocity). Later...

... cells of Cajal (ICC) that are electrically coupled to smooth muscle cells. The myogenically driven component of gastrointestinal motility patterns in fish probably also involves ICC; however, little is known of their presence, distribution and function in any fish species. In the present study, we...

...Gen L. Takei; Daisuke Miyashiro; Chinatsu Mukai; Makoto Okuno Many studies have been conducted to elucidate the relationship between energy metabolic pathways (glycolysis and respiration) and flagellar motility in mammalian sperm, but the contribution of glycolysis to sperm motility has not yet...

... simultaneously and the average parameters of the cells' motility are calculated. The time-dependent, two-dimensional distribution of swimming velocities is measured and the three-dimensional distribution is recovered by assuming horizontal isotropy. The mean and variance of the cell turning angle are quantified...

...R. L. Ingermann; M. Holcomb; M. L. Robinson; J. G. Cloud SUMMARY Maintenance of sperm at pH values less than approximately 7.5 inhibited the onset of motility when sperm were subsequently diluted with water; maintenance at pH values above approximately 8.2 was associated with maximal motility upon...

... may also be involved in its resistance; that is, while some dynein arms are inducing active sliding others are responsible for restricting the sliding and thereby causing bending to occur. Despite extensive tests to detect a significant difference between the motile characteristics of 9+1 and 9+2...
