In this research, the nanoorganic reagent 4 (4-sulphophenylazo) pyrogallol was prepared by method of forming diazonium salt in an acidic medium coupling compound sulfadiazine with pyrogallol. The complex iron (III) also prepared. and were diagnosed through electronic spectrometers, UV-Visible Spectrophotometers, IR, X-ray diffraction measurements, XRD, 1H-NMR-C13-NMR measurements. effect solven...

Abstract Background Pulmonary hypertension (PH) is a significant complication of mitral regurgitation (MR), leading to worse outcomes [1]. PH not prominent at rest during an early stage MR, but could be induced stress. Elevated levels natriuretic peptides are related subclinical myocardial injury [2,3] including elevated systolic pulmonary artery pressure (SPAP) and it has prognostic impact in ...

Abstract Background B-lines detected by lung ultrasound (LUS) during exercise stress echocardiography (ESE), indicating pulmonary congestion, are present in 1 out of 3 patients with hypertrophic cardiomyopathy (HCM). Aim To assess the functional and anatomical correlates HCM. Methods We enrolled 191 HCM (age 53±15 years, 123 males) consecutively referred for ESE (treadmill 74, bicycle 117 patie...

Vitamin D deficiency actives renin-angiotensin-aldosterone system (RAAS) which affects cardiovascular system. Activation of RAAS is associated with pulmonary hypertension (PHT). Relation between vitamin D deficiency and PHT could be therefore suggested. In our study we compared pulmonary artery pressure between vitamin D deficiency and control groups. 115 consecutive patients (average age: 61.8...

Right ventricle (RV) dysfunction is a key outcome determinant and a leading cause of death for patients with chronic thromboembolic pulmonary hypertension (CTEPH). In this report, we followed the 5-year clinical journey of a patient with CTEPH. The tricuspid pressure gradient was significantly increased in the early phase of CTEPH and "normalized" at the late phase of this patient's clinical jo...

We consider the relation between strategy−proofness of resolute (single−valued) social choice functions and its property which we call Non−negative association property (NNAP) when individual preferences over infinite number of alternatives are continuous, and the set of alternatives is a metric space. NNAP is a weaker version of Strong positive association property (SPAP) of Muller and Sattert...

Abstract Funding Acknowledgements Type of funding sources: None. Background Pulmonary hypertension (PH) is a high mortality and an uncrackable disease up to date. The complex pathophysiology one the reasons for only view treatment that can be given patients with PH. Recent studies have found ras human orthologue–kinase (Rho-kinase) plays role in pulmonary hypertension. Rho-kinase maintains vaso...

Abstract Background Many patients with chronic thromboembolic pulmonary disease (CTEPD) without hypertension (PH) at rest suffer from exercise intolerance. Exercise echocardiography, which is a noninvasive examination, may have potential to discover exercise-induced PH in these patients, however, its role scarcely explored this population. Purpose To determine the occurrence of abnormal pressur...
