Increased lung endothelin-1 production in rats with idiopathic pulmonary hypertension

Autor: Ivan F. McMurtry, T. Sakurai, Masashi Yanagisawa, K. Sato, S. Webb, James H. Fisher, Thomas J. Stelzner, Martin R. Zamora, R. F. O'Brien

Publikováno v: American Journal of Physiology-Lung Cellular and Molecular Physiology. 262:L614-L620

The role of endogenous circulating or locally produced endothelin-1 (ET-1) in pulmonary hypertensive states is unknown. To investigate this we measured ET-1 levels and preproendothelin-1 (prepro-ET-1) mRNA expression at various ages in control Spragu

Serum endothelin-1 concentrations and cold provocation in primary Raynaud's phenomenon

Autor: M R, Zamora, R F, O'Brien, R B, Rutherford, J V, Weil

Publikováno v: The Lancet. 336:1144-1147

To determine whether the vasoconstriction in Raynaud's phenomenon is associated with raised concentrations of the endothelium-derived vasoconstrictor endothelin (ET-1), responses to cold pressor testing were examined in 7 subjects with primary Raynau

Application of intrawell testing of RCRA groundwater monitoring data when no upgradient well exists

Autor: C J, Chou, R F, O'Brien, D B, Barnett

Publikováno v: Environmental monitoring and assessment. 71(1)

A statistical quality control approach to detect changes in groundwater quality from a regulated waste unit is described. The approach applies the combined Shewhart-CUSUM control chart methodology for intrawell comparison of analyte concentrations ov

Pulmonary capillaritis and alveolar hemorrhage associated with the antiphospholipid antibody syndrome

Autor: R S, Crausman, G A, Achenbach, W T, Pluss, R F, O'Brien, C A, Jennings

Publikováno v: The Journal of rheumatology. 22(3)

Pulmonary hemorrhage due to small vessel vasculitis is a well recognized complication of many autoimmune and collagen vascular disorders. The antiphospholipid antibody syndrome (APS) is a disorder associated with hypercoagulability, thrombocytopenia,

Late disassembly of a modular acetabular component. A case report

Autor: R F, O'Brien, D, Chess

Publikováno v: The Journal of arthroplasty.

Disassembly of metal-backed acetabular components used for total hip arthroplasty is becoming more common in both preassembled and modular designs. This complication is usually associated with a dislocation of the femoral component or other radiograp

Effects of hypoxia on endothelium-dependent relaxation of rat pulmonary artery

Autor: K. Hasunuma, R. F. O'Brien, Takashi Yamaguchi, David M. Rodman, Ivan F. McMurtry

Publikováno v: The American journal of physiology. 258(4 Pt 1)

We have previously reported that the isolated rat branch pulmonary artery (PA) contracts when made hypoxic and that the contraction is dependent in large part on the presence of a functioning endothelium. This study tested if the hypoxic contraction

Hypoxia-induced increases in pulmonary transvascular protein escape in rats. Modulation by glucocorticoids

Autor: John V. Weil, Thomas J. Stelzner, R F O'Brien, K Sato

Publikováno v: Journal of Clinical Investigation. 82:1840-1847

Pulmonary edema after ascent to altitude is well recognized but its pathogenesis is poorly understood. To determine whether altitude exposure increases lung vascular permeability, we exposed rats to a simulated altitude of approximately 14,500 feet (
