| The generation of a draft sequence of the human genome has lead to an opportunity to characterize human diversity, including the differences in host response to numerous pathogens. Host responses upon exposure to a pathogen can determine the wide spectrum of illness from subclinical or mild to severe diseases. Host factors, particularly genetic backgrounds, influence the pathogenesis of infectious diseases.... |
| Objective : A probable diagnosis of Wiskott-Aldrich syndrome(WAS) should be considered in any boy presenting with unusual bleeding, congenital thrombocytopenia and small platelets. The definitive diagnosis of WAS is usually made by the detection of WASP gene mutation or a decrease or absence of the WAS protein(WASP) in blood cells using molecular genetic analysis. However, these methods are too time-consuming... |
| Persistent pulmonary hypertension of the newborn(PPHN) is a disorder characterized by persistence of the pattern of fetal circulation after birth due to a sustained elevation of pulmonary vascular resistance. The two primary events in the pathophysiology of neonatal pulmonary hypertension are hypoxic pulmonary vasoconstriction(HPV) and hypoxic pulmonary vascular remodeling(HPR). Chronic hypoxemia may cause increased muscularity of the pulmonary arteries and... |
