the cyclical changes in the gonadotropins stimulate ovarian follicular development either to the ovulatory stage or to undergo atresia. one such intrafollicular factor may be inter-cellular communication via gap junctions. we have examined the effects of two agents (retinoids and alkanols), known to disrupt or uncouple gap junction, on fsh-stimulated lh receptor induction and progestrone synthe...
Hyaluronic acid (HA)-based (sub)micron hydrogel particles were synthesized by crosslinking virgin HA with divinyl sulfone (DVS) in sodium bis(2-ethylhexyl)sulfosuccinate (AOT) reverse micelle systems under basic conditions. Experimental parameters including HA molecular weight, solution concentration, and reaction time were systematically varied in order to obtain well defined hydrogel particle...

Neuron membrane changes and ion redistribution during normoxic spreading depression (SD) induced, for example, by potassium injection, closely resemble those that occur during hypoxic SD-like depolarization (HSD) induced by oxygen withdrawal, but the degree to which the two phenomena are related is controversial. We used extracellular electrical recording and imaging of intrinsic optical signal...
