Reproductive Outcomes for Women With Vasculitis.

Objective: There are limited data on the reproductive health of women with vasculitis. This study used a prospective, international vasculitis pregnancy registry to survey women during and after pregnancy.

Methods: The Vasculitis Pregnancy Registry (VPREG) is imbedded within the Vasculitis Patient-Powered Research Network, an international online research infrastructure.

SRD-1 in AWA neurons is the receptor for female volatile sex pheromones in males.

Pheromones are critical cues for attracting mating partners for successful reproduction. Sexually mature virgin females and self-sperm-depleted hermaphrodites produce volatile sex pheromones to attract adult males of both species from afar. The chemoresponsive receptor in males has remained unknown.

Cosuppression of the chloroplast localized molecular chaperone HSP90.5 impairs plant development and chloroplast biogenesis in Arabidopsis.

Background: HSP90.5 is a chloroplast localized HSP90 family molecular chaperone in Arabidopsis, and it has been implicated in plant abiotic stress resistance, photomorphogenesis and nuclear-encoded protein import into the chloroplast. However, how these processes are controlled by HSP90 is not well understood.

Comparing a ciliate and a fish cell line for their sensitivity to several classes of toxicants by the novel application of multiwell filter plates to Tetrahymena.

Although ciliated protozoa such as Tetrahymena have many desirable properties as toxicological test organisms, their attributes would be better realized if multiple cultures could be simultaneously exposed to toxicants, quickly washed to terminate toxicant exposure, and conveniently evaluated for changes in cellular functions. Therefore, multiwell filter plates (MWFPs), manufactured primarily for biochemical applications, were used to expose Tetrahymena thermophila to copper, Triton X-100, and gliotoxin and compared to results of exposure in microcentrifuge tubes (MCTs). For MWFP, removal of toxicant solutions and retention of Tetrahymena in wells was done by placing plates on a manifold and applying pressure with a vacuum pump.
