Histamine is present in high concentrations in the intestine and we investigated the possibility that it might have a role here in intestinal transport. When added to the basal side of rabbit ileal mucosa in vitro histamine (10(-4)M) induced a short-lived increase in electrical potential difference and short circuit current. It inhibited net chloride absorption but did not influence sodium tran...
Drugs targeting atrial-specific ion channels, Kv1.5 or Kir3.1/3.4, are being developed as new therapeutic strategies for atrial fibrillation. However, current preclinical studies carried out in non-cardiac cell lines or animal models may not accurately represent the physiology of a human cardiomyocyte (CM). In the current study, we tested whether human embryonic stem cell (hESC)-derived atrial ...
The current study was done to test the hypothesis that protein kinase C (PKC) inhibitors prevent the increase in pulmonary vascular resistance and compliance that occurs in isolated, blood-perfused dog lungs during hypoxia. Pulmonary vascular resistances and compliances were measured with vascular occlusion techniques. Hypoxia significantly increased pulmonary arterial resistance, pulmonary ven...
The pedunculopontine nucleus (PPN) is a component of the reticular activating system (RAS), and is involved in the activated states of waking and rapid eye movement (REM) sleep. Gamma oscillations (approximately 30-80 Hz) are evident in all PPN neurons and are mediated by high-threshold voltage-dependent N- and P/Q-type calcium channels. We tested the hypothesis that high-speed calcium imaging ...
This paper aims to explore whether pretreatment with dexmedetomidine (Dex) has antioxidative and renal protective effects during orthotopic autologous liver transplantation (OALT) and its impact on nuclear factor erythroid 2-related factor 2 (Nrf2) activation. Sprague-Dawley rats were randomized into groups that include sham-operated (group S), model (group M), low dose Dex (group D1), high dos...
PURPOSE To assess the impact of beta-blocker therapy on quality of life (QoL) in chronic heart failure (CHF) patients receiving optimal standard medication. METHODS Randomised controlled trials (RCT) assessing QoL with a generic or disease specific instrument were identified by searching Medline, Embase, Pascal, Cochrane Controlled Trial database, and the bibliographies of the published artic...
