The fertility potential of an artificial insemination (AI) dose is a function of the quantity, quality and health status of the semen contained therein. Therefore, identification of additional semen quality attributes associated with fertility could provide more accurate methods to predict, manage and select for AI sire fertility of predicting a bull's fertility rat. The objective of this study...

Sperm motility is an important parameter for success in intracytoplasmic sperm injection (ICSI) treatment. The sperm motility is due to its tail. If the sperm is not moving, it could be dead or alive. Normal live births have been obtained after ICSI with immotile sperm [1,2]. Various procedures have been applied to pick viable sperm for ICSI including, hypo-osmotic swelling (HOS) test [3], addi...

Pollen tube cell volume changes rapidly in response to perturbation of the extracellular osmotic potential. This report shows that specific phospholipid signals are differentially stimulated or attenuated during osmotic perturbations. Hypo-osmotic stress induces rapid increases in phosphatidic acid (PA). This response occurs starting at the addition of 25% (v/v) water to the pollen tube culture...

Osmotic loading of articular cartilage has been used to study cell-tissue interactions and mechanisms in chondrocyte volume regulation in situ. Since cell volume changes are likely to affect cell's mechanotransduction, it is important to understand how environmental factors, such as composition of the immersion medium and temperature affect cell volume changes in situ in osmotically challenged ...

Sudden exposure of dissociated hippocampal neurons to strongly hypoor hyperosmotic solutions suppresses voltage gated Na +, K + and Ca 2+ currents. We investigated whether ligand gated ion currents were similarly shut down by exposure to anisosmotic solutions. The effect of hypo-osmotic, NaCI deficient (mannitol-substituted), or hyper-osmotic test solutions delivered from a flow pipette was tes...
