OBJECTIVE The prodrug oseltamivir has been shown to be efficacious and safe for the treatment of influenza for patients 1 year of age or older; however, pharmacokinetic information was lacking for children below 5 years of age. This study was conducted to assess the metabolic and excretory capacity of oseltamivir and its active carboxylate metabolite in(More)
BACKGROUND Oseltamivir dose reduction is recommended for patients with end-stage renal disease (ESRD). However, dosing recommendations are not available for treatment or prophylaxis of influenza in these patients. This study assessed the pharmacokinetics and tolerability of oseltamivir in ESRD patients undergoing maintenance haemodialysis (HD) and(More)
Tirilazad mesylate pharmacokinetics were assessed in 12 young and 12 elderly volunteers (six men and six women per age group). Subjects received single 10-minute intravenous infusions of 1.5 mg/kg and 3.0 mg/kg tirilazad mesylate. Plasma tirilazad mesylate concentrations were determined by HPLC. There were no significant dose effects on clearance, but(More)
We measured forearm bone mineral content by single photon absorptiometry together with height, weight and the plasma concentrations of testosterone, free testosterone and sex steroid binding globulin in 66 normal Caucasian males aged 29-46 years. Multiple regression analysis suggests that bone mineral content in either the dominant or the nondominant arm is(More)
BACKGROUND Seventy-three healthy, male subjects randomly divided into 3 groups participated in a study to determine the effects of 2 high-calorie nutritional supplements on body composition, body segment circumferences, and muscular strength following a resistance-training (RT) program. METHODS In addition to their normal diets group 1 (CHO/PRO; n=26)(More)
Twelve volunteers completed a two-sequence, three-way crossover study of a single 900-mg aspirin dose and multiple doses of 75 mg of oseltamivir in the absence and presence of 900 mg of aspirin. The plasma and urine results demonstrated no pharmacokinetic interaction between oseltamivir and aspirin.
BACKGROUND The aetiology and pathophysiology of ulcerative colitis remains unclear; however, there is increasing recognition of the critical role of inflammatory cytokines in the pathogenesis of this disease. Among these, tumour necrosis factor alpha (TNF alpha) seems to play an important role. AIM To study the effects of an engineered human monoclonal(More)
A 23 year old woman presented with facial pain, a right parotid tumour and iron deficiency anaemia. She had several cutaneous venous swellings and tumours with a similar appearance were found in the large bowel. Histological examination of the parotid tumour and angiography of the skin and gut lesions confirmed that they were venous in origin. The(More)
Fluciclovine (18F) is a novel positron emission tomography (PET)/computerised tomography (CT) tracer. This blinded image evaluation (BIE) sought to demonstrate that, after limited training, readers naïve to fluciclovine (18F), could interpret fluciclovine (18F) images from subjects with biochemical recurrent (BCR) prostate cancer with acceptable diagnostic(More)
Atevirdine is a nonnucleoside reverse transcriptase inhibitor of human immunodeficiency virus type 1 (HIV-1). In this study we investigated the effect of atevirdine in asymptomatic antiretroviral naive HIV-infected patients with CD4+ cell counts of between 200 and 750 cells per mm3. Patients were randomized to receive 600 mg of atevirdine (n = 15) or a(More)
