Caracterização do vírus da raiva isolado de uma colônia de morcegos Eptesicus furinalis, do Brasil
Some bat species have adapted to the expanding human population by acquiring the ability to roost in urban buildings, increasing the exposure risk for people and domestic animals, and consequently, the likelihood of transmitting rabies. Three dead bats were found in the yard of a house in an urban area of Jundiaí city in the state of São Paulo in southeast Brazil. Two of the three bats tested positive for rabies, using Fluorescent Antibody and Mouse Inoculation techniques. A large colony of Eptesicus furinalis was found in the house's attic, and of the 119 bats captured, four more tested positive for rabies. The objectives of this study were to report the rabies diagnosis, characterize the isolated virus antigenically and genetically, and study the epidemiology of the colony.Algumas espécies de morcegos têm se adaptado ao uso de abrigos em construções urbanas, aumentando a possibilidade de contato desses morcegos com pessoas e animais domésticos e conseqüentemente, o potencial risco de transmissão de raiva. Três morcegos foram encontrados no jardim de uma casa na área urbana da cidade de Jundiaí, Estado de São Paulo, Sudeste do Brasil, dois deles foram positivos para raiva pelas técnicas de imunofluorescência e inoculação em camundongos. Uma grande colônia de E. furinalis foi identificada, vivendo no sótão da casa e 119 morcegos foram encaminhados para diagnóstico de raiva, com mais quatro morcegos positivos. O objetivo desse estudo é apresentar a caracterização genética e antigênica do vírus da raiva isolado desses morcegos e o estudo epidemiológico da colônia
A História da Alimentação: balizas historiográficas
Os M. pretenderam traçar um quadro da História da Alimentação, não como um novo ramo epistemológico da disciplina, mas como um campo em desenvolvimento de práticas e atividades especializadas, incluindo pesquisa, formação, publicações, associações, encontros acadêmicos, etc. Um breve relato das condições em que tal campo se assentou faz-se preceder de um panorama dos estudos de alimentação e temas correia tos, em geral, segundo cinco abardagens Ia biológica, a econômica, a social, a cultural e a filosófica!, assim como da identificação das contribuições mais relevantes da Antropologia, Arqueologia, Sociologia e Geografia. A fim de comentar a multiforme e volumosa bibliografia histórica, foi ela organizada segundo critérios morfológicos. A seguir, alguns tópicos importantes mereceram tratamento à parte: a fome, o alimento e o domínio religioso, as descobertas européias e a difusão mundial de alimentos, gosto e gastronomia. O artigo se encerra com um rápido balanço crítico da historiografia brasileira sobre o tema
Heterogeneous contributions of change in population distribution of body mass index to change in obesity and underweight NCD Risk Factor Collaboration (NCD-RisC)
From 1985 to 2016, the prevalence of underweight decreased, and that of obesity and severe obesity increased, in most regions, with significant variation in the magnitude of these changes across regions. We investigated how much change in mean body mass index (BMI) explains changes in the prevalence of underweight, obesity, and severe obesity in different regions using data from 2896 population-based studies with 187 million participants. Changes in the prevalence of underweight and total obesity, and to a lesser extent severe obesity, are largely driven by shifts in the distribution of BMI, with smaller contributions from changes in the shape of the distribution. In East and Southeast Asia and sub-Saharan Africa, the underweight tail of the BMI distribution was left behind as the distribution shifted. There is a need for policies that address all forms of malnutrition by making healthy foods accessible and affordable, while restricting unhealthy foods through fiscal and regulatory restrictions
Students' preferred teaching techniques for biochemistry in biomedicine and medicine courses
The aim of this study was to investigate the students' preferred teaching techniques, such as traditional blackboard, power-point, or slide-projection, for biochemistry discipline in biomedicine and medicine courses from São Paulo State University, UNESP, Botucatu, São Paulo, Brazil. Preferences for specific topic and teaching techniques were determined from questionnaires on a Liquert scale from 1 to 5 (strongly disagree; disagree; neither agree, nor disagree; agree; strongly agree) distributed at the end of biochemistry discipline to 180 biomedical students (30 students/year) and 540 medical students (90 students/year), during the years 2000-2005. Despite of the different number of hours applied to the course topics for the two groups of students, the majority of undergraduates from biomedicine and medicine preferred metabolic topics. Although the perception of a medical student is expected to be different than that of a biomedical student, as the aims of the two programs are different, 92.4% of students from each course agreed or strongly agreed with the biochemistry topics, and 92.1% thought highly on this subject. The majority of students, a number of 139 undergraduates from biomedicine and 419 from medicine course, preferred traditional blackboard teaching than slide-projection, or power-point class. In conclusion, it is imperative that the health courses reflect on sophisticated technology and data presentation with high density of information in biochemistry discipline. The traditional classes with blackboard presentation were most favored by students from biomedicine and medicine courses. The use of students' preferred teaching techniques might turn biochemistry more easily understood for biomedical and medical students. © 2007 by The International Union of Biochemistry and Molecular Biology
Técnicas de ensino na disciplina de Bioquímica preferidas pelos estudantes dos Cursos de Biomedicina e Medicina
O objetivo do presente trabalho foi identificar a técnica de ensino de Bioquímica preferida pelos alunos dos cursos de graduação em Biomedicina e Medicina, da Universidade Estadual Paulista, UNESP, Botucatu, desde que, a utilização desta técnica de ensino pode facilitar o aprendizado e a fixação dos conhecimentos. Foram comparadas técnicas de ensino tradicional, com uso de quadro-negro, projeção de slides e power-point. A preferência por técnicas de ensino foi determinada através de questionários utilizando-se escala de Liquert, distribuídos para 180 alunos do curso de Biomedicina (30 alunos/ano) e 540 alunos de Medicina (90 alunos/ano), durante o período de 2000 a 2005. 92,4% dos estudantes concordaram, ou concordaram fortemente com os tópicos abordados e reconheceram a importância da disciplina de bioquímica para os respectivos cursos. A maioria dos estudantes demonstrou preferência pelo estudo do metabolismo, em relação aos aspectos estruturais. 139 graduandos de Biomedicina e 419 de Medicina preferiram o método tradicional com explanação oral e uso do quadro-negro. Conclui-se que estudantes dos cursos de Biomedicina e Medicina contestam técnicas sofisticadas no ensino de bioquímica, preferindo o método tradicional, com apresentação gradual do conteúdo programático, permitindo discussões sobre os tópicos e a adequada fixação dos conhecimentos
Rutin ameliorates glycemic index, lipid profile and enzymatic activities in serum, heart and liver tissues of rats fed with a combination of hypercaloric diet and chronic ethanol consumption
215-222Alcoholism
and obesity are strongly associated with several disorders including heart and
liver diseases. This study evaluated the effects of rutin treatment in serum,
heart and liver tissues of rats subjected to a combination of hypercaloric diet
(HD) and chronic ethanol consumption. Rats were divided into three groups:
Control: rats fed a standard diet and drinking water ad libitum; G1:
rats fed the HD and receiving a solution of 10% (v/v) ethanol; and G2: rats fed
the HD and ethanol solution, followed by injections of 50 mg/kg-1
rutin as treatment. After 53 days of HD and ethanol exposure, the rutin was
administered every three days for nine days. At the end of the experimental
period (95 days), biochemical analyses were carried out on sera, cardiac and
hepatic tissues. Body weight gain and food consumption were reduced in both the
G1 and G2 groups compared to control animals. Rutin effectively reduced the
total lipids (TL), triglycerides (TG), total cholesterol (TC), VLDL,
LDL-cholesterol and glucose levels, while it increased the HDL-cholesterol in
the serum of G2 rats, compared to G1. Although rutin had no effect on total
protein, albumin, uric acid and cretinine levels, it was able to restore serum
activities of alkaline phosphatase (ALP), lactate dehydrogenase (LDH),
aspartate aminotransferase (AST), alanine aminotransferase (ALT) and creatine
kinase (CK) in animals fed HD and receiving ethanol. Glycogen stores were
replenished in both hepatic and cardiac tissues after rutin treatment.
Moreover, rutin consistently reduced hepatic levels of TG and TC and cardiac AST,
ALT and CK activities. Thus, rutin treatment was effective in reducing the risk
factors for cardiac and hepatic disease caused by both HD and chronic ethanol
consumption.
