Polychlorinated biphenyls (PCBs) and the structurally related polybrominated diphenyl ethers (PBDEs) are abundant persistent organic pollutants that exert several comparable neurotoxic effects. Importantly, hydroxylated metabolites of PCBs and PBDEs have an increased neurotoxic potency. Recently, we demonstrated that PCBs can act as (partial) agonist on GABAA neurotransmitter receptors, with PC...

Regulatory Integrative Comp. Physiol. 278: R563–R571, 2000.—The purpose of the present study was to use the microdialysis technique to simultaneously measure the interstitial concentrations of several putative stimulators ...

Zhang, Rong, Julie H. Zuckerman, and Benjamin D. Levine. Spontaneous fluctuations in cerebral blood flow: insights from extended-duration recordings in humans. Am J Physiol Heart Circ Physiol 278: H1848–H1855, 2000.—To determine the dependence of cerebral blood flow (CBF) on arterial pressure over prolonged time periods, we measured beat-to-beat changes in mean CBF velocity in the middle cerebr...

Mennitt, Patricia A., Gustavo Frindt, Randi B. Silver, and Lawrence G. Palmer. Potassium restriction downregulates ROMK expression in rat kidney. Am J Physiol Renal Physiol 278: F916–F924, 2000.—The ROMK family of proteins has biophysical properties and distribution within the kidney similar to those of secretory potassium channels of the distal nephron. To study the regulation of ROMK during v...

Am J Physiol Regulatory Integrative Comp Physiol 278: R1107– R1110, 2000.—Six human subjects performed one-legged knee extensor exercise (90 6 4 W) until fatigue (exercise time 4.6 6 0.8 min). Needle biopsies were obtained from vastus latera...

Welsh, Donald G., and Steven S. Segal. Role of EDHF in conduction of vasodilation along hamster cheek pouch arterioles in vivo. Am J Physiol Heart Circ Physiol 278: H1832– H1839, 2000.—We tested whether local and conducted responses to ACh depend on factors released from endothelial cells (EC) in cheek pouch arterioles of anesthetized hamsters. ACh was delivered from a micropipette (1 s, 500 nA...
