BACKGROUND The aim of this study was to assess the probability of low-grade squamous intra-epithelial lesion (LSIL) regression in young women, and to examine the factors associated with this regression. METHODS In a longitudinal study of human papilloma virus (HPV) infection, female adolescents aged 13-22 years were examined every 4 months by cytology,(More)
In several vertebrate species it has been clearly demonstrated that neural circuits within the spinal cord are capable of generating the signals underlying locomotory rhythms. In the present paper a halfcentre model is proposed for the spinal locomotor generator which is based entirely on the connections and properties of known spinal neurones. In its(More)
An open, non-comparative study of 10 weeks' duration was conducted in general practice to assess the safety of amlodipine in patients with mild to moderate hypertension. Of the 5352 patients entering the study, 5135 received amlodipine; 4621 patients (90%) with a mean age of 58.2 years completed the study. Normalisation of blood pressure was achieved in(More)
The purpose of this study was to investigate the stereospecific pharmacokinetics of ketorolac (KT) in goats following a single 2 mg/kg intravenous (i.v.) dose and a single 6 mg/kg oral dose. A stereoselective high pressure liquid chromatography assay was used to quantify ketorolac plasma concentrations. Pharmacokinetic parameters for both stereoisomers were(More)
The frequency of an abnormally anterior insertion of scalenus anterior to the scalene tubercle on the superior aspect of the 1st rib was examined as a possible contributory factor to venous compression syndromes and to difficulties in cannulation of the subclavian vein. The insertion of scalenus anterior was exposed bilaterally in 21 adult cadavers and its(More)
This study addressed the question of how caterpillars of Archips cerasivoranus feeding upon Prunus virginiana cope with the cyanogenic compounds of their food. Analysis by ion chromatography showed that young and aged leaves of P. virginiana consumed by the caterpillars during spring have hydrogen cyanide potentials (HCN-ps) of 2,473 ± 130 ppm and 1,058 ±(More)
