BACKGROUND Angiotensin (Ang) II type 2 (AT2) receptor stimulation results in coronary vasodilation in the rat heart. In contrast, AT2 receptor-mediated vasodilation could not be observed in large human coronary arteries. We studied Ang II-induced vasodilation of human coronary microarteries (HCMAs). METHODS AND RESULTS HCMAs (diameter, 160 to 500 microm) were obtained from 49 heart valve dono...

Aims. The analysis of SN1987A led Brown and Bethe (1995) to conclusion, that the maximum mass of cold neutron stars is low, Mmax ≈ 1.5 M⊙. Such a low Mmax, due to a kaon condensation in the stellar core, implies collapse of a too massive deleptonized protoneutron star into a black hole. This would naturally explain the lack of a neutron star in the SN1987A remnant. On the other hand, recent eva...

We give a unified proof of algorithmic weak and Szemerédi regularity lemmas for several well-studied classes sparse graphs, which only were previously known. These include core-dense low threshold rank (a version of) upper regular graphs. More precisely, we define cut pseudorandom prove our these then show that pseudorandomness captures all the above graph as special cases. The core approach is...

OBJECTIVE Two measures of the response rate and the optimal treatment response for adult ADHD were evaluated using methylphenidate. The hypotheses were that Prediction of ADHD (PADHD) defines remission, the Weighed Core Symptom (WCS) scale registers direct effects of medication and that WCS may indicate the optimal dose level during titration. DESIGN PADHD and WCS were analyzed at baseline an...

Four simple and sensitive methods for the assay of prazosin hydrochloride (PRH) are developed. These methods are based on the formation of coloured species by treating it either with excess N-bromosuccinimide (NBS) and determining the unconsumed NBS with p-N-methyl aminophenol sulphate (metol)-sulphanilamide (SA) reagent (method A, lambda(max) 520 nm): with 3-methyl-2-benzothiazolinone hydrazon...
