this study has examined the functional importance of nucleus accumbens (nac)-ventral tegmental area (vta) interactions. as it is known, this interaction is important in associative reward processes. under urethane anesthesia, extracellular single unit recordings of the shell sub-region of the nucleus accumbens (nacsh) neurons were employed to determine the functional contributions of the vta to...

background: diagnosis of coronary artery disease (cad) in patients with left bundle branch block (lbbb) is considered as a challenge in cardiology due to the low accuracy of noninvasive methods such as basal and stress electrocardiography (ecg). this diagnostic challenge can be reduced but not eliminated using dipyridamole as a stress method instead of exercise. the aim of this study was to ass...

introduction: we aimed to investigate of effect of left bundle branch block (lbbb) on perfusion and functional parameters in dipyridamole tc99m-mibi gated myocardial perfusion spect which may be helpful in interpretation of myocardial perfusion imaging. methods: we studied 70 patients with low pre-test probability of coronary artery disease in two groups:  35 patients with lbbb and  35 subjects...

let $r$ be a reversible ring which is $alpha$-compatible for an endomorphism $alpha$ of $r$ and $f(x)=a_0+a_1x+cdots+a_nx^n$ be a nonzero skew polynomial in $r[x;alpha]$. it is proved that if there exists a nonzero skew polynomial $g(x)=b_0+b_1x+cdots+b_mx^m$ in $r[x;alpha]$ such that $g(x)f(x)=c$ is a constant in $r$, then $b_0a_0=c$ and there exist nonzero elements $a$ and $r$ in $r$ such tha...

This study describes the effects of the substituents on electrochemical behavior and antioxidant activity of the three tetradentate Schiff bases, containing ethane-1,2- diamine, propane-1,3- diamine and butan-1,4- diamine as the amine part and salicylaldehyde, and corresponding Cd(II) complexes. Cyclic voltammograms of these compounds were recorded in dimethylsulfoxide and 0.1 M sodium perchlor...

Platelet activation and adhesion to the site of vascular injury is a dynamic process comprising reversible and irreversible phases. Platelet adhesion typically occurs in a multi-step process similar to the selectin/integrin-mediated adhesion of neutrophils. This phenomenon is highly regulated and influenced by the cross-talk between platelets and injured endothelium. This cross-talk involves a ...
