A 57-year-old male with no significant past medical history called the emergency services with a 4-h history of sudden-onset central chest pain associated with nausea, vomiting, sweating and an episode of collapse. The on-site electrocardiogram (ECG) demonstrated ST-segment elevation in the anterior, inferior and lateral leads (Figure 1) and he was transferred urgently to the regional percutane...

Irradiation instructs mast cells to rebuild blood vessels in oxygen-deprived tissues, according to Heissig and colleagues on page 739. Low-dose irradiation mobilized adult and precursor mast cells, which traveled to the ischemic tissue and produced the vessel-building growth factor VEGF (vascular endothelial growth factor). Ionizing irradiation has been shown to promote the growth of new blood ...

  Objective(s): Apolipoprotein E genotype (APOE) polymorphism affects lipid levels and coronary artery disease (CAD) risk. The aim of this study was to study the association of the Apolipoprotein E genotypes with coronary artery disease in the Iranian population.   Materials and Methods: The Apolipoprotein E genotype in DNA samples extracted from 66 CAD+ patients and 61 control s...

Finite element method is employed to analyze the spherical vessel intersected by an oblique cylindrical nozzle. In this survey the stress and strain distributions on acute and obtuse sides of the connection under internal pressure are studied widely although axial and moment loadings on the nozzle are also studied briefly. Stress concentration factors for a wide range of geometrical ratios in t...
