The hypothermic response of rats to only brief ( approximately 2 h) hypoxia has been described previously. The present study analyzes the hypothermic response in rats, as well as level of activity (L(a)), to prolonged (63 h) hypoxia at rat thermoneutral temperature (29 degrees C). Mini Mitter transmitters were implanted in the abdomens of 10 adult(More)
It is thought that radiation treatment inhibits neovascularization of recipient and/or graft tissues, and this may account in part for abnormalities in wound healing associated with radiation therapy. We have examined this hypothesis using a model that measures the neovascularization of an implanted foreign material. Expanded polytetrafluoroethylene (PTFE)(More)
Adult Lepidoptera are capable of associative learning. This helps them to forage flowers or to find suitable oviposition sites. Larval learning has never been seriously considered because they have limited foraging capabilities and usually depend on adults as concerns their food choices. We tested if Spodoptera littoralis larvae can learn to associate an(More)
BACKGROUND A diagnostic test that could distinguish between stable and unstable coronary atherosclerotic plaques would be useful. We tested the ability of a new glycoprotein IIb/IIIa platelet inhibitor DMP-444, labeled with technetium (Tc)-99 m, to identify platelet-rich thrombus by nuclear imaging in a canine model. METHODS AND RESULTS Combinations of a(More)
STUDY OBJECTIVE To determine the effect of metoprolol on dobutamine stress testing with technetium-99m sestamibi single-photon emission computed tomography imaging and ST-segment monitoring, and to assess the impact of intravenous glucagon on metoprolol's effects. DESIGN Randomized, double-blind, placebo-controlled trial. SETTING Community hospital. (More)
Six years after apparent complete recovery from intestinal Whipple's disease, a 56 year old man developed insidious progressive somnolence and gait ataxia. Studies showed hydrocephalus with obstruction of the aqueduct and CSF leukocytosis and elevated protein. Arachnoid biopsy during craniotomy revealed chronic inflammatory infiltration with PAS-positive(More)
OBJECTIVE To compare the results of retroperitoneal laparoscopic adrenalectomy using the antegrade and retrograde approach. MATERIALS AND METHODS We performed an analysis of a single-center series of 279 retroperitoneal laparoscopic adrenalectomies from 1996 to 2010. We compared 172 cases performed with an antegrade approach and 107 with a retrograde(More)
That migraine can present with a severe headache of sudden onset mimicking that of subarachnoid hemorrhage--the so-called "complicated migraine with meningeal manifestations" of Pearce and Foster--is not readily appreciated. Over the past three years, seven patients have been referred to us with a presumable diagnosis of subarachmoid hemorrage. In each one(More)
INTRODUCTION AND OBJECTIVES Indication of laparoscopic adrenalectomy for adrenal metastasis remains debated. Our aim was to analyze its carcinological results. MATERIAL AND METHODS In a series of 332 laparoscopic adrenalectomies, 13 were for adrenal metastasis (kidney=5, lung=3, melanoma=3, breast=1, eye=1). The indication was curative (single metastasis)(More)
The treatment of ten cases of ectopic anus is presented in this paper. The association of constipation with perineal anus due to alignment disturbance of the external sphincter triple loop system during evacuation has been described by Hendren (1978), Leape and Ramenofsky (1978), Upadhyaya (1984) et al. Hendren, Leape and Ramenofsky described two valid(More)
