OBJECTIVE To assess the influence of preload reduction by hemodialysis on Doppler Tei Index of myocardial performance and other parameters of cardiac function. METHODS The Tei index and left ventricular (LV) systolic and diastolic function parameters were estimated, before and after a single hemodialysis session. Only subjects who were in sinus rhythm, without history of coronary artery disea...

AIMS The purpose of this study was to evaluate whether yoga training in addition to standard medical therapy can improve cardiac function and reduce N terminal pro B-type natriuretic peptide (NT pro BNP) in heart failure (HF). METHODS 130 patients were recruited and randomized into two groups: Control Group (CG) (n = 65), Yoga Group (YG). In YG, 44 patients and in CG, 48 patients completed th...

OBJECTIVE A recent study concerning high-altitude pulmonary edema (HAPE), a non-cardiogenic pulmonary edema, suggested that it is initially a hydrostatic-type pulmonary edema. We suspect that some extent of cardiac insufficiency may likely relate to the mechanism of the development of this disease. METHODS By Doppler echocardiography, the Tei index (a new quantitative index proposed for the e...

Elucidating the correlation among tourism, CO2 emissions, and economic growth from a spatiotemporal standpoint is of utmost significance for tourism industry responding to China’s “double-carbon” goal. This study expansively uses bottom-up approach, Theil index, Exploratory Spatial Data Analysis (ESDA), Logarithmic Mean Divisia Index (LMDI) method calculate emissions (TE) at different spatial s...

Introducción: Esta investigación fue realizada con 24 estudiantes inscritos en la Licenciatura Enseñanza de Idiomas Universidad Benito Juárez (Oaxaca, México). El objetivo conocer cómo tutoría entre iguales (TEI), método caracterizado por formación parejas alumnos que se enseñan mutuamente un contenido curricular, ayuda a desarrollar las funciones docentes básicas. Los recibieron sobre TEI y as...

BACKGROUND The metabolic syndrome (MS) represents a cluster of cardiovascular risk factors that act synergistically. OBJECTIVE The aim of this study was to determine which parameters were independently associated with the global left ventricular (LV) function in subjects with MS estimated with the Tei index. METHODS The study included 234 subjects with MS and 96 controls adjusted by age. MS...

Two structurally different antagonists of the nuclear hormone 1alpha,25-dihydroxyvitamin D(3) [1alpha,25(OH)(2)D(3)], the 25-carboxylic ester ZK159222 and the 26,23-lactone TEI-9647, have recently been described. In this study, the molecular mechanisms and the efficacy of both antagonists were compared. ZK159222 showed similar potency and sensitivity to 1alpha,25(OH)(2)D(3) in ligand-dependent ...

Lipoglycopeptide antibiotics are more effective than vancomycin against MRSA as they carry an extra aliphatic acyl side chain on glucosamine (Glm) at residue 4 (r4). The biosynthesis of the r4 N-acyl Glc moiety at teicoplanin (Tei) or A40926 has been elucidated, in which the primary amine nucleophile of Glm is freed from the r4 GlcNac pseudo-Tei precursor by Orf2* for the subsequent acylation r...

Left ventricular (LV) hypertrophy and dysfunction due to hypertension have been established as risk markers for stroke in hypertensive patients. The purpose of this study was to examine the differences in LV hypertrophy and dysfunction between patients with cerebral hemorrhage and those with cerebral infarction. The study enrolled 23 hypertensive patients with cerebral infarction, 25 hypertensi...

UNLABELLED Aims/Introduction:  Diabetic cardiomyopathy entails the cardiac injury induced by diabetes, independent of vascular disease or hypertension. Despite numerous experimental studies and clinical trials, the pathogenesis of diabetic cardiomyopathy remains elusive. Here, we report that chymase, an immediate angiotensin II (AngII)-forming enzyme in humans and hamsters, and NOX4-induced oxi...
