Mechanical ventilation, a fundamental therapy for acute lung injury, worsens pulmonary vascular permeability by exacting mechanical stress on various components of the respiratory system causing ventilator associated lung injury. We postulated that MK2 activation via p38 MAP kinase induced HSP25 phosphorylation, in response to mechanical stress, leading to(More)
Sixty previously untreated patients with high grade non-Hodgkin's lymphomas stages II-IV received cyclophosphamide 750 mg m2 i.v., doxorubicin 50 mg m2 i.v., and vincristine 2 mg i.v. on day 1, prednisolone 100 mg p.o. on days 1-5 and etoposide 100 mg m2 i.v. on days 3-5 (CHOP-VP16). After four courses an involved field irradiation with a total dose of 25(More)
BACKGROUND Xanthine oxidoreductase (XOR) is involved in oxidative metabolism of purines and is a source of reactive oxygen species (ROS). As such, XOR has been implicated in oxidant-mediated injury in multiple cardiopulmonary diseases. XOR enzyme activity is regulated, in part, via a phosphorylation-dependent, post-translational mechanism, although the(More)
African Americans (AA) with systemic sclerosis (SSc) have a worse prognosis compared to Americans of European descent (EA). We conducted the current study to test the hypothesis that AA patients with SSc have more severe disease and poorer outcomes compared to EA patients when afflicted with pulmonary arterial hypertension (PAH). We studied 160 consecutive(More)
BACKGROUND The effect of heart rate (HR) and body surface area (BSA) on pulmonary RC time and right ventricular (RV) load is unknown. METHODS To determine the association of HR and BSA with the pulmonary RC time and measures of RV load, we studied three large patient cohorts including subjects with 1) known or suspected pulmonary arterial hypertension(More)
