The present study evaluates renal dopaminergic activity in 23 patients with heart failure (HF), 10 age-matched controls, and 10 young subjects during normal-salt (NS) intake and after 8 days of low-salt (LS) intake (patients with HF and age-matched controls only).

Blood-derived lactate is a precious energy substrate for the heart muscle. Lactate is transported into cardiomyocytes via monocarboxylate transporters (MCTs) together with H(+), which couples lactate uptake to cellular pH regulation. In this study, we have investigated how the interplay

Mitochondrial ATP-sensitive potassium channel (mitoK(ATP)) is a common end effector of many protective stimuli in myocardial ischemia-reperfusion injury (MIRI). However, the specific molecular mechanism underlying its myocardial protective effect is not well elucidated. We characterized an anoxia/reoxygenation (A/R) model using

Although infection with the human enteropathogen Giardia lamblia causes self-limited diarrhea in adults, infant populations in endemic areas experience persistent pathogen carriage in the absence of diarrhea. The persistence of this protozoan parasite in infants has been associated with reduced

Malignant transformation of gastric epithelial cells by chronic Helicobacter pylori infection is caused by several mechanisms including attraction of reactive oxygen species (ROS)-producing neutrophils and cytotoxin-associated antigen A-mediated dysplastic alterations. Here we show that H.pylori protects transformed cells from ROS-mediated

Prepulse inhibition (PPI) of the startle reflex, a measure of sensorimotor gating, is decreased in schizophrenia. The validity of a glutamatergic, N-methyl-d-aspartate receptor (NMDAR)-mediated model of PPI disruption is presently equivocal. The NMDAR antagonist ketamine disrupts PPI in rodents, but

Background We determined if the sodium glucose co-transporter 2 inhibitor empagliflozin attenuates pressure overload-induced heart failure in non-diabetic mellitus mice by direct cardiac effects and the mechanisms involved. Methods and Results Male C57BL/6J mice (4-6 months of age) were subjected to

Some native epithelia, for example, retinal pigment epithelium (RPE) and kidney proximal tubule (KPT), constitutively lack the basolateral sorting adaptor AP-1B; this results in many basolateral plasma membrane proteins being repositioned to the apical domain, where they perform essential functions

Pathophysiological conditions challenge cell volume homeostasis and perturb cell volume regulatory mechanisms leading to alterations of cell metabolism, active transepithelial transport, cell migration, and death. We report that inhibition of the 5-lipoxygenase (5-LO) with AA861 or ETH 615-139, the cysteinyl
