BACKGROUND: Advanced breast biopsy instrumentation is a recently designed alternative to large-core stereotactic and open needle localized breast biopsies. This minimally invasive technique uses digital stereotactic imaging to perform excisional…
Purpose: To compare three decision making techniques using a common clinical problem. Methods: Two recently developed methods, the analytic hierarchy process (AHP) and the analytic network process (ANP), were compared with a Markov process in the…
Oral lichenoid lesions caused by hypersensitivity to mercury in amalgam fillings may mimic oral lichen planus on clinical and histologic examination. A positive patch test reaction to more than one mercurial allergen increases confidence in the…
Experiments were undertaken to determine whether angiotensin (Ang) II concentration increases during massive sympathetic nervous system (SNS) activation and whether such an increase plays a role in the pathogenesis of SNS-induced left ventricular…
Chromium(V)-mediated oxidative damage of deoxyribonucleic acids was investigated at neutral pH in aqueous solution by utilizing bis(2-ethyl-2-hydroxybutanato)oxochromate(V) (I) and bis(hydroxyethyl)amino-tris(hydroxymethyl)methane)oxochromate(V)…
Objectives: To describe emergency medicine (EM) residency program research requirements, characterize research directors (RDs), and describe their research activities and productivity. Methods: A survey with questions addressing program research…
A 57-year-old woman presented with a rash on her legs that had recurred several times over the last 2 weeks. Initial treatment consisted of prednisone, 30 mg/day, for 5 days, but the rash had recurred when therapy was discontinued. Laboratory…
Prenatal human immunodeficiency virus (HIV) screening may reduce vertical HIV transmission. We screened 4,419 prenatal sera and found 38 repeatedly reactive specimens with an HIV-1-HIV-2 enzyme-linked immunosorbent assay. Western blot analysis…
Over 30 nuclei have been identified in the reticular formation of rats, but only a small number of distinct reticular nuclei have been recognized in frogs. We used immunohistochemistry, retrograde tracing, and cell morphology to identify nuclei…
A WIN 35,055-2 analog, 3 beta-(4-iodophenyl)tropane-2 beta-pyrrolidine carboxamide (RTI-229), has been radiolabelled with iodine-125 by radioiododestannylation of the corresponding trimethyltin derivative using carrier-free sodium iodide-125 as the…
Oxysterol 7 alpha-hydroxylase has broad substrate specificity for sterol metabolites and may be involved in many metabolic processes including bile acid synthesis and neurosteroid metabolism, The cloned human oxysterol 7 alpha-hydroxylase (CYP7B1)…
At the low temperatures of the overwintering environment of the frog Rana temporaria, small changes in ambient temperature have large effects on metabolism and behaviour, especially since Q(10) values are often greatly elevated in the cold. How the…
Background: Epidemiological data indicate that approximately 20% of children have psychosocial problems, yet less than 2% of children are seen by mental health specialists each year. Primary care physicians tend to identify children with psychosocial…
