AIMS Endothelin (ET) antagonists show promise in animal models of cirrhosis and portal hypertension. The aim was to pharmacologically characterise the expression of endothelin receptors in human liver, hepatic artery and portal vein. MAIN METHODS Immunofluorescence staining, receptor autoradiography and competition binding assays were used to localise and quantify ET receptors on hepatic pare...

to determine the droplet characteristics of agricultural spray nozzles through water sensitive paper (wsp), the non-circular and overlapped spots appearing on the water sensitive paper surfaces are eliminated. in the conventional approach, the procedure is done according to the subjective self determined estimation of the operator. the objective of this study was to develop a practical alternat...

Rac1, caveolin-1 and vascular endothelial growth factor-mediated liver sinusoidal endothelial cell angiogenesis Rac1 and cell morphogenesis In this issue of Liver International, Yokomori et al. (1) detailed how Rac1, a member of the Rho-GTPases protein family, plays a key role in the migration of liver sinusoidal endothelial cells (LSECs) and in the subsequent process of capillary-like tubular ...

Wireless power transmission is based on electromagnetical phenomenon between two separate coils. In order to transfer power from one to the other, we have to cause a time-varying current along one coil. Many of conventional wireless power transmission systems suppose a sinusoidal current of the coil. One reason for it could be the convenience that we have a sinusoidal power source as the indust...

A magnetic field induced by an electromagnetic coil is the key variable that determines performance of a magnetically driven actuator. The applicability empirical models turns, static resistance, and inductance were discussed. Then, model mean was established analytically. Based on proposed model, sinusoidal response square-wave calculated with wire diameter as decision variable. amplitude phas...

This paper presents a multicomponent sinusoidal model of speech signals, obtained through a rigorous mathematical formulation that ensures an asymptotically exact reconstruction of these nonstationary signals, despite the presence of transients, voiced segments, or unvoiced segments. This result has been obtained by means of the iterated use of the Hilbert transform, and the convergence propert...
