MP2/6-31++G** and B3LYP/6-31++G** ab initio molecular orbital calculations have been performed in order to obtain molecular geometries, binding energies and vibrational properties of the C2H2-HF, C2H(CH3)-HF and C2(CH3)2-HF H-bonded complexes. As expected, the more pronounced effects on the structural properties of the isolated molecules due to complexation was verified for the C[triple bond]C ...

Background Although the left ventricle is the major site of BNP secretion in response to cardiac pressure or volume overload, the myocytes of both atria and ventricles secrete B- type natriuretic peptide (BNP). This study aimed to assess and compare the plasma levels of BNP in common pediatric cardiac diseases to clarify its pathophysiological role and evaluate its po...

objectives this study aimed to examine the effect of a hospital-based educational program based on the constructs of the health belief model (hbm) on self-care behaviors of patients with hf. methods this controlled quasi-experimental study consisted of 84 patients with hf (42 patients in an intervention group and 42 in a control group) who were admitted to two large, specialized, referral hospi...

BACKGROUND We hypothesized that patients with heart failure (HF) who recover left ventricular function (HF-Recovered) have a distinct clinical phenotype, biology, and prognosis compared with patients with HF with reduced ejection fraction (HF-REF) and those with HF with preserved ejection fraction (HF-PEF). METHODS AND RESULTS The Penn Heart Failure Study (PHFS) is a prospective cohort of 182...

Radio waves provide a useful diagnostic tool to investigate the properties of ionosphere because affects transmission and High Frequency (HF) electromagnetic waves. We have conducted transionospheric HF-propagation research campaign with nanosatellite on low-Earth polar orbit EISCAT HF transmitter facility in Troms{\o}, Norway, December 2020. In active measurement, transmitted sinusoidal 7.953 ...

Increased morbidity and mortality associated with ischemic heart failure (HF) in type 2 diabetic patients requires a deeper understanding of the underpinning pathogenetic mechanisms. Given the implication of microRNAs (miRNAs) in HF, we investigated their regulation and potential role. miRNA expression profiles were measured in left ventricle biopsies from 10 diabetic HF (D-HF) and 19 nondiabet...
