The role of adenosine 3',5'-cyclic monophosphate (cAMP)-dependent protein kinase A (PKA) in mediating the hydrosmotic effect of vasopressin in in vitro microperfused rabbit cortical collecting ducts (CCDs) was examined. We measured PKA substrate phosphorylation and water permeability [hydraulic conductivity (Lp) = 10(-7) cm.atm-1.s-1], stimulated by(More)
We examined the effect of carbachol, an acetylcholine analogue, on hydraulic conductivity (Lp) response to 10 microU/ml arginine vasopressin (AVP) in rabbit cortical collecting duct (CCD). In CCDs in which water flow had been established with AVP, subsequent addition of carbachol caused Lp (X10(-7) cm.atm-1.s-1) to fall from 251 +/- 32 to 146 +/- 19.(More)
Sensory ethnography has been employed to proffer anthropological understandings that extend beyond the written word, and in many cases, sensory ethnographers have gravitated toward the study of both contemporary and traditional livelihoods. Yet ethnographic inquiries made outside of textual forms of representation, inclusive of those concerning livelihoods,(More)
