We investigated the contribution of sarcoplasmic reticulum (SR) and Na+/Ca2+ exchanger in the tension-dependent change in the decay of the Ca2+ transients (CaT) in euthyroid (Eu) and hyperthyroid (Hy) myocardium. Hy was induced by thyroxine treatment to enhance the rate of SR Ca2+ uptake. With the use of the aequorin method, CaT and tension in twitch contraction were simultaneously measured und...

A stable, hydrogen-defect structure of post-perovskite (hy-ppv, Mg1 xSiH2xO3) has been determined by first-principles calculations of the vibrational and elastic properties up to 150 GPa. Among three potential hy-ppv structures analyzed, one was found to be stable at pressures relevant to the lower-mantle D 00 region. Hydrogen has a pronounced effect on the elastic properties of post-perovskite...

We propose a method that is able to analyze chaotic time series, gained from experimental data. The method allows to identify scalar time-delay systems. If the dynamics of the system under investigation is governed by a scalar time-delay differential equation of the form dy(t) dt = h(y(t), y(t−τ0)), the delay time τ0 and the function h can be recovered. There are no restrictions to the dimensio...

Five species of Hymenoscyphus that fruit on black stromatized parts of dead leaves of deciduous trees are presented, giving details on their morphological and ecological characteristics. Several of these species have previously been misplaced in rutstroemiaceous genera because of the presence of a substratal stroma. However, the heteropolar, scutuloid ascospores with an often hook-like lateral ...

This paper introduces a new class called hang yourself (HY) arguments into the theory of defeasible argumentation. The novelty of such arguments is that they are inherently destructive: they cannot be used to support conclusions but only to attack other arguments. In this paper it is described what these arguments are, how they can be formalized, and what the formal consequences are of adding t...

Heat stroke (HS) is characterized by a systemic inflammatory response syndrome (SIRS) consisting of profound core temperature (Tc) changes in mice. Encephalopathy is common at HS collapse, but inflammatory changes occurring in the brain during the SIRS remain unidentified. We determined the association between inflammatory gene expression changes in the brain with Tc disturbances during HS reco...

the objectives of this study were to determine the diversity, seasonal dynamics and abundance of ticks infesting cattle in isfahan zone, iran. the study was conducted in three traditional cattle farms. no acaricides had been applied to cattle at the selected farms. adult ticks were collected twice per month from different parts of the cattle's body. environmental data, including relative h...
