Electrogenicity of the Na(+)/K(+) pump has the capability to generate a large negative membrane potential independently of ion-channel current. The high background membrane resistance of arterioles may make them susceptible to such an effect. Pump current was detected by patch-clamp recording from smooth muscle cells in fragments of arterioles (diameter(More)
OBJECTIVE To investigate the mechanism of K(+)-induced vasodilation in a small artery from the kidney, with a particular emphasis on the role of inward rectifier K+ channels. METHODS Lumen diameter and isometric tension recordings have been made from rabbit renal arcuate artery using pressurised- and wire-myography respectively. In addition, conventional(More)
The aim of this project was to develop a method to enable routine application of all patch-clamp configurations to smooth muscle cells while they remain embedded in blood vessels. Small blood vessels were isolated from rabbit brain using an enzymatic and mechanical procedure. Vessels were identified under a microscope and the majority were small arterioles(More)
We have previously shown expression of voltage-gated K+ channels (K(V)) in smooth muscle of cerebral arterioles and suggested the channels function to oppose voltage-dependent Ca2+ entry. However, other studies indicate that large conductance Ca2+-activated K+ (BK) channels serve this function and chloride (Cl-) channels may have the opposite effect. In(More)
OBJECTIVE To describe various approaches for ureterolysis with an omental wrap using minimally invasive techniques, as surgery for idiopathic retroperitoneal fibrosis includes tissue biopsy, ureterolysis, and intraperitonealization or omental wrap. PATIENTS AND METHODS Since 2006 we have performed ureterolysis in four patients diagnosed with(More)
An in depth study of how the psychological behaviors affect construction safety" (2010). Abstract Construction safety has been overlooked and the construction industry is now ranked 2 nd in top fatalities (Bureau of Labor Statistics (BLS), 2009). As new laws and regulations are being set forth and incentive programs being produced, companies are becoming(More)
