Left ventricular function is related with amphiregulin and fibrosis markers in cirrhotic cardiomyopathy.

The relationship between left ventricle (LV), extracellular matrix remodeling and fibrosis-linked amphiregulin (ARG) in cirrhotic cardiomyopathy (CCM) is unknown. The aim of the study was to investigate the associations between markers of extracellular matrix remodeling and ARG in cirrhosis and their association with indicators of ventricular remodeling and LV functional parameters. In hepatitis C virus (HCV) patients with cirrhosis, who underwent echocardiography, the presence of left ventricular diastolic dysfunction (LVDD) was determined by having gradable diastolic dysfunction in accordance with modified 2020 Cirrhotic Cardiomyopathy Consortium criteria.

Solid-State NMR Provides Evidence for Small-Amplitude Slow Domain Motions in a Multispanning Transmembrane α-Helical Protein.

Proteins are dynamic entities and populate ensembles of conformations. Transitions between states within a conformational ensemble occur over a broad spectrum of amplitude and time scales, and are often related to biological function. Whereas solid-state NMR (SSNMR) spectroscopy has recently been used to characterize conformational ensembles of proteins in the microcrystalline states, its applications to membrane proteins remain limited.

[The clinical value of computer tomography (CT) of diagnostics of acute thorax pain--a literature review].

Conventional angiography of the coronary arteries is a standard in heart and coronary arteries diagnosis, sufficient to choose a treatment method. The introduction of 64-row multidetector computed tomography improved the imaging of coronary arteries by increasing its spatial and temporal resolution. It has been shown that the potential clinical value of CT angiography, including dual source computed tomography (DSCT), is based particularly on the exclusion of coronary artery disease and is now a recognized clinical indication in patients with equivocal stress test results.
