BACKGROUND Pergolide produces clinical benefit in Parkinson disease by stimulating dopamine D1 and D2 receptors. An increased incidence of carcinoid-like heart valve disease (CLHVD) has been noted in pergolide users, reminiscent of that induced by certain anorexigens used for weight reduction. Anorexigens that modulate serotonin release and reuptake, such… (More)
The shortnose sturgeon, Acipenser brevirostrum, oft considered a phylogenetic relic, is listed as an "endangered species threatened with extinction" in the US and "Vulnerable" on the IUCN Red List. Effective conservation of A. brevirostrum depends on understanding its diversity and evolutionary processes, yet challenges associated with the polyploid nature… (More)
The effector mechanism of hypoxic pulmonary vasoconstriction (HPV) involves K' channel inhibition with subsequent membrane depolarization. It remains uncertain how hypoxia modulates K' channel activity. The similar effects of hypoxia and mitochondrial electron transport chain (ETC) inhibitors on metabolism and vascular tone suggest a common mechanism of… (More)
Objective of Research: Assessment of time-series satellite data as landscape indicators; development and implementation of classification scheme for watershed condition.
Common names: Sterlet (E) Kecsege (Hu) Cega (Ro) Jeseter maly (Slov). Conservation status: Under IUCN, listed as Endangered in principal rivers (Volga, Danube) entering the Caspian and Black seas. Hungarian and Romanian sector of Danube population listed as Vulnerable. Dnieper River population listed as Endangered. In Siberia, the Ob, Irtysh and Yenisei… (More)
Movements of the endangered shortnose sturgeon Acipenser brevirostrum in the Ogeechee River (Georgia, USA) may be limited by unsuitable habitat conditions during June–September. The research objective was to determine if habitat quality is likely to impede movements and spawning of shortnose sturgeon in this system. We inserted ultrasonic transmitters in 18… (More)
Nonforested herbaceous vegetation communities represent a key ecosystem in montane environments, providing habitat for a diverse range of animal species. The montane meadow cover types occur below timberline, but are ecologically and geographically distinct from lower-elevation nonforested intermontane parklands. The objective of this project was to… (More)
