The restenosis or occlusion that frequently follows balloon angioplasty is poorly understood. Thus, the pathophysiological response to angioplasty of the common carotid artery in 38 heparinized normal pigs was investigated by quantification of the 111In-labeled platelet deposition and histological and electron microscopic examination from 1 hour to 60 days(More)
This study retrospectively evaluated the outcome for patients undergoing herniorraphy for chronic groin pain due to posterior inguinal wall deficiency, and correlated the outcome with preoperative investigation findings. There were 47 patients (with a total of 52 herniorraphies) who were contacted by phone between six and 50 months post surgery. Subjects(More)
UNLABELLED We examined the cases of 702 patients found to have isolated atrial septal defect of the secundum or sinus venosus type at catheterization from 1953 to 1978. Forty patients (6%), 34 women and six men, had pulmonary vascular obstructive disease, with a total pulmonary resistance greater than 7 U/m2; of these patients 26 (mean age 47 years)(More)
During the last decade, significant advances have been made in the understanding of the pathogenesis of coronary atherosclerotic disease. Two facts are important: 1) the early and some of the advanced coronary atherosclerotic lesions progress very slowly, probably by means of a complex stepwise biologic process with one of the steps being an interaction(More)
We studied the effects of a cold pressor test on the plasma catecholamine levels of ten patients undergoing coronary angiography, to determine whether the pressor changes were related to adrenergic activity. To investigate the relative contribution of adrenal medullary catecholamine release, we subjected two adrenalectomised volunteers to the same test.(More)
BACKGROUND Platelet-thrombus formation is a complication of arterial wall deep injury by balloon angioplasty that may lead to acute arterial occlusion and may contribute to restenosis. METHODS AND RESULTS Because common platelet-inhibitor drugs with a heparin bolus (100 units/kg) may be effective in inhibiting platelet-thrombus formation after arterial(More)
make this task virtually impossible. Thus, smoking gun experiments will probably require new technologies such as in vivo imaging of (many) individual synapses or the ability to tag recently modified synapses with a marker. Until then, the best approaches will require a series Houston, Texas 77030 of indirect observations that together support involvement(More)
We have reported that pigs with severe homozygous von Willebrand disease (vWd) are resistant to spontaneous and high fat, high cholesterol, diet-induced atherosclerosis. In this study we report the quantitation of aortic atherosclerotic plaques in three groups of pigs fed with a high fat, high cholesterol (2%) diet from age 3 to 9 months. Nine normal pigs(More)
The expression of the c-myc proto-oncogene product was examined by immunohistochemistry in 11 normal breast tissues, 31 invasive and 14 non-invasive breast carcinomas. The c-myc product was detected in all breast carcinoma specimens and in seven of 11 normal breast tissues. Invasive tumors stained more frequently with the anti-myc monoclonal antibody (MAb)(More)
During a multicenter study 57 patients with exercise-induced angina were evaluated with serial exercise testing to assess the efficacy of diltiazem, a calcium slow channel blocking agent, compared with a placebo. The study consisted of a 1 week single-blind placebo stabilization period followed by a double-blind triple crossover between diltiazem and(More)
