Ten extracts with different polarity from two Iranian Artemisia species, A. armeniaca Lam. and A. aucheri Boiss, were screened for their antimalarial properties by in vitro   β -hematin formation assay. Dichloromethane (DCM) extracts of both plants showed significant antimalarial activities with IC50 values of 1.36±0.01 and 1.83±0.03 mg/mL and IC90 values of 2.12±0.04 and 2.62±0.09 mg/mL for A....

To clarify the abnormalities of myocardial membrane structure in cardiomyopathy, the density of intramembranous particles (IMP) of mitochondria, sarcoplasmic reticulum and sarcolemma, and the number of caveolar necks was evaluated by freeze-fracture morphology. The subjects consisted of 17 patients with hypertrophic cardiomyopathy (HCM), 6 patients with dilated cardiomyopathy (DCM), and 7 patie...

Dynamic causal modeling (DCM) is a generic Bayesian framework for inferring hidden neuronal states from measurements of brain activity. It provides posterior estimates of neurobiologically interpretable quantities such as the effective strength of synaptic connections among neuronal populations and their context-dependent modulation. DCM is increasingly used in the analysis of a wide range of n...

Dilated cardiomyopathy (DCM) is characterized by left ventricular dilation, and is associated with systolic dysfunction and increased action potential duration. Approximately 50% of DCM cases are caused by inherited gene mutations with genetic and phenotypic heterogeneity. Next generation sequencing may be useful in screening unknown mutations in such cases.A family was identified with DCM, in ...

Dilated cardiomyopathy (DCM) is a heart disease characterized by progressive depression of cardiac function and left ventricular dilatation of unknown etiology in the absence of coronary artery disease. Genetic causes and cardiotoxic substances account for about one third of the DCM cases, but the etiology of the remaining 60% to 70% is still unclear. Over the past two decades, evidence has acc...

Background: Dilated cardiomyopathy (DCM) is revealed with the left ventricular dilatation and systolic dysfunction. This study was performed to determine the level of Calcitonin Gene Related Peptide (CGRP) and Brain Natriuretic Peptide (BNP) in children with dilated cardiomyopathy and controls and comparison of these two biomarkers in patients. Materials and Methods: This case-control study was...

AIMS The mutations most frequently associated with dilated cardiomyopathy (DCM) have been reported in the lamin A/C gene. The role of variants of the lamin A/C gene was investigated in patients with DCM from eastern and southern Finland. METHODS AND RESULTS All 12 exons of the lamin A/C gene were screened in 18 well-characterised familial DCM patients from eastern and southern Finland and in ...

BACKGROUND The presence of apoptotic myocytes has been reported in human hearts with dilated cardiomyopathy (DCM) on the basis of a positive finding of DNA in situ nick end-labeling (TUNEL). However, ultrastructural evidence of myocyte apoptosis has not been obtained. METHODS AND RESULTS A total of 80 endomyocardial biopsies were obtained from right and left ventricles of 20 patients with DCM...

New methods for the analysis of arrhythmias and their hemodynamic consequences have been applied in risk stratification, in particular to patients after myocardial infarction. This study investigates the suitability of short-term heart rate turbulence (HRT) analysis in comparison to heart rate and blood pressure variability as well as baroreceptor sensitivity analyses to characterise the regula...

Dilated cardiomyopathy (DCM) is characterized by ventricular dilatation, and it is a common cause of heart failure and cardiac transplantation. This study aimed to explore potential DCM-related genes and their underlying regulatory mechanism using methods of bioinformatics. The gene expression profiles of GSE3586 were downloaded from Gene Expression Omnibus database, including 15 normal samples...
