  • Sickle Cell Disease Case Study

    Special delivery of toxic cell-free heme causes vascular damage in Sickle Cell Disease Scientists describe a novel mechanism responsible for blood vessel injury in Sickle Cell Disease (SCD): microparticles derived from sickle cells deliver heme to the vascular endothelial cells causing oxidative damage. Sickle Cell Disease (SCD) is an inherited blood disorder caused by a single base mutation in the DNA of affected patients, producing abnormal hemoglobin molecules. In SCD, red blood cells…

  • Superior Vena Cava Syndrome Case Study

    use of intravascular catheters, pacemakers and defibrillators are becoming a more common cause of SVCS.

  • Arterial Stiffness

    of the vessel walls, with reconstruction taking place in order to recompense for the differences in wall pressure. Along with relating to various structural causes, vessel function can have an impact on the arterial stiffness as well, with the endothelium and, especially, nitric oxide being primary determinants (Payne, Wilkinson, & Webb, 2010). General knowledge on the subject of dynamic fluctuations in arterial stiffness continues to be rather insufficient; for that reason, the causes of…

  • Medication Errors Case Study Essay

    Coronary artery disease due to atherosclerosis is the most common cause of unstable angina. Arteries are blood vessels that carry blood from the heart throughout the body and there is a thin layer of cells called the endothelium, which helps keep the arteries toned and smooth to keep blood flowing.

  • Nipah Virus Essay

    For the initial entry of the virus, the ephrinB2 domain is necessary. Once entered through micropinocytosis, protease cathespin L activates the virus (12). Nipah Virus can replicate very easily in human lung fibroblasts. It can infect the surrounding cells by either cell-to-cell spread or through release of infectious particles. When monocytes get infected, they can transmigrate through the blood brain barrier to infect the brain. This could be plausible if the monocytes were inefficient in…
