1. High-risk behaviors for hepatitis B and C infections among female sex workers
Abstract INTRODUCTION: The prevalence of hepatitis B and hepatitis C and risk behaviors among 402 female sex workers in Central Brazil were investigated by respondent-driven sampling. METHODS: Blood samples were tested for hepatitis B and C markers by enzyme-linked immunosorbent assay. Two hepatitis B vaccination schedules were performed. RESULTS: The

2. Evaluation of the effects on different doses and sampling schedules on the assessment of bioequivalence / Avaliação de diferentes cronogramas de coletas de amostras biológicas em estudos de bioequivalência e análise da influência de teor de fármaco sobre os resultados destes estudos
Os estudos de bioequivalência são realizados em humanos, por meio da administração dos medicamentos em estudo pela mesma via extravascular, sob condições experimentais padronizadas, seguida pela determinação das concentrações plasmáticas do fármaco em função do tempo. Nestes estudos considera-se que curvas estatisticamente semelhantes de decaim

3. Sunburn in adolescents and young adults: a population-based study in Southern / Queimadura solar e fatores associados a sua ocorrência: um estudo de base populacional na cidade de Pelotas, RS.
Objective: to evaluate the prevalence of sunburn and its risk factors among subjects aged between 10 and 29 years in urban area of Pelotas, a Southern Brazilian city. Methods: a cross-sectional population based study, using a multiple stage sampling, was carried out between October and December of 2005. Sunburn was defined as burning of the skin after sun ex

4. Biological evaluation of recombinant human erythropoietin in pharmaceutical products
The potencies of mammalian cell-derived recombinant human erythropoietin pharmaceutical preparations, from a total of five manufacturers, were assessed by in vivo bioassay using standardized protocols. Eight-week-old normocythemic mice received a single subcutaneous injection followed by blood sampling 96 h later or multiple daily injections with blood sampl

5. Optimal Sampling Schedule Design for Populations of Patients
Generation of pharmacodynamic relationships in the clinical arena requires estimation of pharmacokinetic parameter values for individual patients. When the target population is severely ill, the ability to obtain traditional intensive blood sampling schedules is curtailed. Population modeling guided by optimal sampling theory has provided robust estimates of

6. Certified sick leave as a non-specific morbidity indicator: a case-referent study among nurses.
A case-referent study assessed the association between medically certified sick leave from work and some occupational characteristics--namely, two work load indices (nurse patient ratio and patients' average duration of stay) and hospital and care unit. Study participants were nurses from seven general hospitals in Québec City who had been employed for at l

7. Role of endogenous opiates in the expression of negative feedback actions of androgen and estrogen on pulsatile properties of luteinizing hormone secretion in man.
We have tested the participation of endogenous opiate pathways in the negative feedback actions of gonadal steroids on pulsatile properties of luteinizing (LH) hormone release in normal men. To this end, sex steroid hormones were infused intravenously at dosages that under steady state conditions selectively suppressed either the frequency or the amplitude o
