Studies on Non-freezing Lubricants

Effect of vaginal lubricants on natural fertility.

OBJECTIVE Over-the-counter vaginal lubricants have been shown to negatively affect in vitro sperm motility. The objective of this study was to estimate the effect of vaginal lubricant use during procreative intercourse on natural fertility. METHODS Women aged 30-44 years with no history of infertility who had been trying to conceive for less than 3 months completed a baseline questionnaire on...

Freezing and melting criteria in non-equilibrium

Using non-equilibrium computer simulations, it is shown that various phenomenological criteria for melting and freezing hold not only in equilibrium but in steady-state non-equilibrium as well. In particular, we study the steady state of charge-polydisperse Brownian particles shaken by a time-dependent oscillatory electric field. Among these criteria are the Lindemann melting rule, the Hansen–V...

Studies on Freezing Injury of Plant Cells: I. Relation between Thermotropic Properties of Isolated Plasma Membrane Vesicles and Freezing Injury.

The thermotropic transition of plasma membrane of Dactylis glomerata was studied by using fluorescence polarization of embedded fluorophore, 1,6-diphenyl-1,3,5-hexatriene. Under the presence of 35% ethylene glycol, reversible thermotropic transitions were observed in isolated plasma membrane vesicles in nearly the same temperature range as the temperature of freezing injury to cells. In liposom...
