Direitos humanos, atitude institucional e simpatia ideológica em universitários brasileiros

Este trabalho teve como objetivo analisar o posicionamento de universitários das regiões norte e nordeste do Brasil sobre os direitos humanos (DH) e a relação desse posicionamento com suas atitudes institucionais, suas simpatias ideológicas e o contexto social em que vivem. Participaram deste estudo 832 universitários do norte e nordeste brasileiro, de ambos os sexos, que responderam a um questionário, contendo escalas que mediam julgamentos sobre 30 direitos, 15 instituições e 10 idéias políticas. Os resultados de uma análise fatorial dos componentes principais sobre os dados referentes aos direitos mostraram a existência de cinco fatores. Os resultados de uma análise de regressão múltipla revelaram a influência das atitudes institucionais e das simpatias ideológicas sobre o envolvimento com os DH; e a influência positiva da região sobre o direito ao protesto social. Os resultados foram discutidos com base em trabalhos empíricos, realizados a partir do referencial psicossociológico.

Confiabilidade e validade das declarações de óbitos por câncer de útero no município de Belém, Pará, Brasil

Belém, Pára, Brasil, apresenta taxas de mortalidade por câncer de colo uterino bastante elevadas, justificando-se a análise da confiabilidade e validade da causa básica do óbito declarada. Selecionou-se declarações de óbito de residentes de Belém, de 1998-1999, com causa básica de morte neoplasia do colo, corpo e porção não especificada do útero e aquelas que mencionavam essas neoplasias em qualquer linha do atestado, totalizando 188 declarações de óbito. Efetuou-se nova codificação para análise da confiabilidade, aferida pela concordância simples e pela estatística kappa. A causa básica do óbito, após revisão de prontuários médicos e/ou laudos histopatológicos, foi considerada como padrão-ouro para análise da validade de critério, através do valor preditivo positivo. Observou-se concordância simples de 94,0% e kappa de 0,87, sugerindo alta confiabilidade na codificação da causa básica câncer de útero no sistema oficial. Na análise da validade, confirmou-se 120 das 127 originais como colo de útero, três das quatro codificadas como corpo de útero e 18 das 48 classificadas como porção não especificada. Registrou-se aumento de 11,2 % nas neoplasias de colo uterino e redução de 62,5% nos óbitos de porção não especificada do útero.

An ethnobotanical study of anti-malarial plants among indigenous people on the upper Negro River in the Brazilian Amazon

In this article we present the plants used for the treatment of malaria and associated symptoms in Santa Isabel do Rio Negro in the Brazilian Amazon. The region has important biological and cultural diversities including more than twenty indigenous ethnic groups and a strong history in traditional medicine. The aims of this study are to survey information in the Baniwa, Baré, Desana, Piratapuia, Tariana, Tukano, Tuyuca, Yanomami ethnic communities and among caboclos (mixed-ethnicity) on: a) plant species used for the treatment of malaria and associated symptoms; b) dosage forms and c) distribution of these anti-malarial plants in the Amazon. Information was obtained through classical ethnobotanical and ethnopharmacological methods from interviews with 146 informants in Santa Isabel municipality on the upper Negro River, Brazil. Fifty-five mainly native neotropical plant species from 34 families were in use. The detailed uses of these plants were documented. The result was 187 records (64.4%) of plants for the specific treatment of malaria, 51 records (17.5%) of plants used in the treatment of liver problems and 28 records (9.6%) of plants used in the control of fevers associated with malaria. Other uses described were blood fortification ('dar sangue'), headache and prophylaxis. Most of the therapeutic preparations were decoctions and infusions based on stem bark, root bark and leaves. These were administered by mouth. In some cases, remedies were prepared with up to three different plant species. Also, plants were used together with other ingredients such as insects, mammals, gunpowder and milk. This is the first study on the anti-malarial plants from this region of the Amazon. Aspidosperma spp. and Ampelozizyphus amazonicus Ducke were the most cited species in the communities surveyed. These species have experimental proof supporting their anti-malarial efficacy. The dosage of the therapeutic preparations depends on the kind of plant, quantity of plant material available, the patient's age (children and adults) and the local expert. The treatment time varies from a single dose to up to several weeks. Most anti-malarial plants are domesticated or grow spontaneously. They are grown in home gardens, open areas near the communities, clearings and secondary forests, and wild species grow in areas of seasonally flooded wetlands and terra firme (solid ground) forest, in some cases in locations that are hard to access. Traditional knowledge of plants was found to be falling into disuse presumably as a consequence of the local official health services that treat malaria in the communities using commercial drugs. Despite this, some species are used in the prevention of this disease and also in the recovery after using conventional anti-malarial drugs.

Winning On for the Gipper: Diversity Strategies and Initiative at Notre Dame

One of the enduring images linked to the University of Notre Dame is that of injured football player George Gipp imploring Coach Knute Rockne to "Win One for the Gipper. " Similarly, people of color and conscience at Notre Dame struggle with formidable challenges in implementing diversity into areas of faculty retention, university initiatives and community outreach, all while remaining sane. The panelists will discuss innovative successes and continuing efforts that can be adapted by others seeking a game plan for diversity.

Fish Oil Supplementation Reduces Cachexia and Tumor Growth While Improving Renal Function in Tumor-Bearing Rats

The objective of the present work was to study the renal function of healthy and tumor-bearing rats chronically supplemented with fish oil (FO), a source of n-3 polyunsaturated fatty acids. Weanling male rats were divided in two groups, one control (C) and another orally supplemented for 70 days with FO (1 g/kg body weight). After this time, half the animals of each group were injected in the right flank with a suspension of Walker 256 tumor cells (W and WFO). The W group had less proteinemia reflecting cachectic proteolysis, FO reversed this fact. Tumor weight gain was also reduced in WFO. Glomerular filtration rate (GFR) was not different in FO or W compared to C, but was higher in WFO. Renal plasma flow (RPF) was higher in the FO supplemented groups. The W group had lower plasma osmolality than the C group, but FO supplementation resulted in normalization of this parameter. Fractional sodium excretion (FENa+) of FO rats was similar to C. Proximal Na+ reabsorption, evaluated by lithium clearance, was similar among the groups. Urinary thromboxane B-2 (TXB2) excretion was lower in the supplemented groups. The number of macrophages in renal tissue was higher in W compared to C rats, but was lower in WFO rats compared to W rats. In conclusion, FO supplementation resulted in less tumor growth and cachexia, and appeared to be renoprotective, as suggested by higher RPF and GFR.

Hepatitis B virus genotypes from European origin explains the high endemicity found in some areas from southern Brazil

Southern Brazil is considered an area of low Hepatitis B endemicity, but some areas of higher endemicity have been described in the Southwest of Parana and Santa Catarina states. The aim of this study was to evaluate viral genotypes circulating throughout Parana state. PCR amplification and partial sequencing of the S gene was carried out in 228 samples from HBsAg positive candidate blood donors. Samples have been collected in seven different counties (Cascavel, Curitiba, Foz do Iguacu, Francisco Beltrao, Matinga Londrina and Paranagua). The most common HBV genotype in Parana state was D (82.9%; 189/228), followed by A (14.1%; 32/228). Genotypes F (1.3%; 3/228), C (1.3%; 3/228) and H (0.4%; 1/228) were also found. Distribution of genotypes was different in the studied counties, but genotype D was the most frequent in all of them. In Francisco Beltrao, all studied samples belonged to genotype D. The high prevalence of HBV genotype Din South of Brazil is explained by the intense migration of settlers from Europeans countries. Subgenotypes A1 and A2 were identified circulating in all cities where HBV/A was found. As observed in other areas of Brazil, HBV/A1 is more frequent than the HBV/A2 in Parana state and its presence was significantly larger in black and mulatto individuals. Genotype C was found only in individuals with Asian ancestry from Londrina and Maringa. Most HBV/F sequences identified in this study were classified as subgenotype F2a that was previously described in Brazil. The sole case of subgenotype F4 was from Foz do Iguacu city, near to Northern Argentina, where F4 is highly prevalent. The single genotype H sample was from Curitiba. This is the first case of this genotype described in Brazil. Further studies should be carried out to determine if more genotype H samples can be found in other populations from Brazil.

Effects of Diets Supplemented with Branched-Chain Amino Acids on the Performance and Fatigue Mechanisms of Rats Submitted to Prolonged Physical Exercise

This study aimed to determine the effects of diets chronically supplemented with branched-chain amino acids (BCAA) on the fatigue mechanisms of trained rats. Thirty-six adult Wistar rats were trained for six weeks. The training protocol consisted of bouts of swimming exercise (one hour a day, five times a week, for six weeks). The animals received a control diet (C) (n = 12), a diet supplemented with 3.57% BCAA (S1) (n = 12), or a diet supplemented with 4.76% BCAA (S2) (n = 12). On the last day of the training protocol, half the animals in each group were sacrificed after one hour of swimming (1H), and the other half after a swimming exhaustion test (EX). Swimming time until exhaustion was increased by 37% in group S1 and reduced by 43% in group S2 compared to group C. Results indicate that the S1 diet had a beneficial effect on performance by sparing glycogen in the soleus muscle (p < 0.05) and by inducing a lower concentration of plasma ammonia, whereas the S2 diet had a negative effect on performance due to hyperammonemia (p < 0.05). The hypothalamic concentration of serotonin was not significantly different between the 1H and EX conditions. In conclusion, chronic BCAA supplementation led to increased performance in rats subjected to a swimming test to exhaustion. However, this is a dose-dependent effect, since chronic ingestion of elevated quantities of BCAA led to a reduction in performance.
