Effect of the Aspect Ratio and Tilt Angle on the Free Convection Heat Transfer Coefficient Inside AlO-Water-Filled Square Cuboid Enclosures.

This experimental study provides a comprehensive investigation of natural convection heat transfer inside shallow square cuboid enclosures filled with aluminum oxide-water nanofluid at four different volume concentrations: 0.0%, 0.2%, 0.

Free convection heat transfer inside square water-filled shallow enclosures.

Experimental study on free convection heat transfer was carried out inside shallow square enclosures filled with water. Two enclosures were used with size L × L × H (m3), where L and H are the side length and the inside thickness of the enclosure, respectively. Two different aspect ratios, κ = L/H, 7.

Soluble fms-Like Tyrosine Kinase 1 as a Link Between Angiogenesis and Endothelial Dysfunction in Pediatric Patients With β-Thalassemia Intermedia.

Endothelial damage has been implicated in the pathogenesis of vascular complications in β-thalassemia intermedia (β-TI). Soluble fms-like tyrosine kinase 1 (sFLT-1) is a member of the vascular endothelial growth factor receptor (VEGFR) family. Soluble fms-like tyrosine kinase 1 is an antiangiogenic protein that induces endothelial dysfunction by adhering to and inhibiting VEGF and placenta growth factor.

Growth differentiation factor-15 in children and adolescents with thalassemia intermedia: Relation to subclinical atherosclerosis and pulmonary vasculopathy.

Background: Heart disease is the leading cause of mortality and one of the main causes of morbidity in β-thalassemia. Growth differentiation factor-15 (GDF-15), a member of the transforming growth factor-β superfamily, is a marker of ineffective erythropoiesis in several anemias.

Aim: To determine GDF-15 levels in children and adolescents with TI and the relation to hemolysis, iron overload and cardiovascular complications.
