Angiotensin II receptors are present along the rat inner medullary collecting duct (IMCD), although their physiological role is unknown. Because urea is one of the major solutes transported across the terminal IMCD, we measured angiotensin II's effect on urea permeability. In the perfused rat terminal IMCD, angiotensin II had no effect on basal urea permeability but significantly increased vaso...

Replication of hepatitis C virus (HCV) RNA is catalyzed by the virally encoded RNA-dependent RNA polymerase NS5B. It is believed that the viral polymerase utilizes a de novo or primer-independent mechanism for initiation of RNA synthesis. Our previous work has shown that dinucleotides were efficient initiation molecules for NS5B in vitro (W. Zhong, E. Ferrari, C. A. Lesburg, D. Maag, S. K. Ghos...

The genus Montenegrina is revised on the basis of material available at the Hungarian Natural History Museum (Budapest), Naturhistorisches Museum Wien (Vienna), and the Naturmuseum Senckenberg (Frankfurt am Main), as well as newly discovered populations. The following new taxa are described: Montenegrina haringae sp. n., Montenegrina lillae sp. n., Montenegrina prokletiana sp. n., Montenegrina ...

AIMS Oesophageal temperature monitoring with single-sensor probe (SSP) has a variable ability to predict oesophageal ulceration as a consequence of pulmonary vein isolation (PVI). Multi-sensor self-expandable probes (MSPs) may offer improved thermal monitoring. The objective of this study was to compare the thermodynamic characteristics of both probes during PVI. METHODS AND RESULTS This pros...

Measuring the viability of probiotic microorganisms in food products using plate count methodology is a common practice due to the simplicity (ease of performance), inexpensive and routine testing characters ofthis method. In present study, the suitability of de man rogosa and sharpe agar (MRS) bile agar medium forthe selective enumeration of mixed probiotic bacteria (Lactobacillus ...
