This article aims to assess: i) the carbon footprint (CF) of particleboard produced in Portugal, and ii) the influence of different methodological issues in the particleboard CF calculation by comparing four CF methodologies (ISO/TS 14067; GHG Protocol Product Standard; PAS 2050; Climate Declaration). A life-cycle model was developed for particleboard (functional unit: 1 m3). Both cradle-to-gate and cradle-to-g...
Doxorubicin (DOX) is an anticancer anthracycline that presents a dose-dependent and cumulative cardiotoxicity as one of the most serious side effects. Several hypotheses have been advanced to explain DOX cardiac side effects, which culminate in the development of life-threatening cardiomyopathy. One of the most studied mechanisms involves the activation of DOX molecule into a more reactive semiquinone by mitoch...
OBJETIVO: Dada a importância do conhecimento acerca da população de cães e gatos domiciliados para o adequado planejamento e avaliação das ações de controle da raiva em áreas urbanas, propõe-se a utilização de um valor preciso de estimativa dessas populações com base em indicadores populacionais humanos. MÉTODOS: Foi calculada a razão entre as populações humana e animal (canina e felina) por meio de inspeções d...
The prevalence of anti-human parvovirus B19 IgG antibodies was determined in sera from 165 chronic hemolytic anemia patients, receiving medical care at Instituto Estadual de Hematologia (IEHE), Rio de Janeiro, during the year of 1994. This sample represents around 10% of the chronic hemolytic anemia patients attending at IEHE. Most of these patients (140) have sickle cell disease. Anti-B19 IgG antibodies were d...
Fecal samples from puppies with gastroenteritis less than 7 months old were examined for canine parvovirus infection (CPV-2) by hemagglutination (HA) and subsequent hemagglutination-inhibition (HI) tests. Forty of the 79 samples collected from April 1995 to June 1997 were found to be positive. About 70% of these samples were from 2 to 4 months old puppies, age in which they are at increased risk of developing C...
INTRODUÇÃO: O tratamento de seres humanos expostos ao risco de infecção pelo vírus rábico ainda pode incluir a ocorrência de reações pós-vacinais indesejáveis, tanto de ordem local como geral. A análise sistemática dos informes epidemiológicos de pacientes submetidos a este tipo de tratamento poderá oferecer subsídios para a modificação desta situação. Foram analisados os registros de tratamento dessa zoonose v...
