[1] We examine the trajectory of Arctic summer sea ice in seven projections from the Community Climate System Model and find that abrupt reductions are a common feature of these 21st century simulations. These events have decreasing September ice extent trends that are typically 4 times larger than comparable observed trends. One event exhibits a decrease(More)
BACKGROUND To establish an accurate diagnosis of diffuse infiltrative lung disease, a surgical lung biopsy may be required. We report our experience with video-thoracoscopic lung biopsy over a period of 5 years. METHODS From March 1992 through December 1996, videothoracoscopic lung biopsy was performed in 64 patients (17 were women [26.5%]; age, 50.5+/-13(More)
BACKGROUND Sea ice across the Arctic is declining and altering physical characteristics of marine ecosystems. Polar bears (Ursus maritimus) have been identified as vulnerable to changes in sea ice conditions. We use sea ice projections for the Canadian Arctic Archipelago from 2006 - 2100 to gain insight into the conservation challenges for polar bears with(More)
The goal of this prospective study was to determine the utility of preoperative cerebral magnetic resonance imaging (MRI) in predicting cerebral ischemia during carotid artery cross-clamping for endarterectomy. Between January 2000 and December 2003, a total of 121 patients (95 men, 26 women) underwent three-dimensional phase-contrast MRI to assess(More)
Bradykinin (BK) and its fragment des-Arg9-BK failed to stimulate thymidine incorporation in all but one observed fibroblast cultures derived from human amniotic fluid or rabbit dermis. The rabbit dermis fibroblast line designated R51 acquired the capacity to increase its DNA synthesis in response to kinins after several weeks in culture. It was more(More)
[1] We introduce the preconditioned generalized minimum residual (GMRES) method, along with an outer loop (OL) iteration to solve the sea-ice momentum equation. The preconditioned GMRES method is the linear solver. GMRES together with the OL is used to solve the nonlinear momentum equation. The GMRES method has low storage requirements, and it is(More)
Some types of rabbit isolated blood vessels precontracted with phenylephrine relaxed when exposed to the chemotactic peptide N-formyl-Met-Leu-Phe (FMLP). The thoracic aorta was unresponsive whereas the portal vein and pulmonary artery exhibited concentration-dependent relaxing responses to FMLP (1-100 nM). FMLP-induced relaxations developed over several(More)
The objective of this prospective study was to evaluate the mortality and morbidity of sarcoma pulmonary metastasis resection with continuous chemotherapy. Ifosfamide was administered at the daily dose of 1200 mg/m2/24 h. Twenty-six resections of pulmonary sarcoma were performed from December 1990 to April 1992. The primary lesion was already resected in(More)
