Abstract: Non-atrophic active chronic gastritis (ACG) is characterized by the presence of H. pylori in the gastric epithelium, known to be one of the first steps that precede progression to gastric adenocarcinoma. Inactive chronic gastritis (ICG) suggests that the patient has H. pylori gastritis, but this diagnosis is rarely made in routine histopathology. Clinical manifestations associated with H. pylori infection are potentially due to differences in virulence between strains; however, it is unclear if the progression of ACG to ICG depends on the H. pylori strain. The aim of this study was to compare the prevalence of the virulence factors of H. pylori found in patients with ACG and ICG, and its influence on the development of ICG. A significant association was observed between H. pylori detection by histological examination and the activity of gastritis (p < 0.01). Long-term use of proton pump inhibitors (PPI) (>1 year) was reported by 28.6% of the ACG group and 42.5% of the ICG, while no evidence of association between long-term use of PPI and decreased inflammation was found in the patients studied. The genes cagA, cagE and virB11 were statistically associated with ACG (p = 0.01, p < 0.001 and p = 0.002, respectively). In the vacAs1 allele groups, ACG was associated with the most virulent group (p = 0.0015), while ICG was associated with the less virulent group (p < 0.001). The rate of co-infection was significantly higher in ICG than in ACG cases (p = 0.02). In conclusion, this study points to the role of virulent strains of H. pylori in the non-resolution of gastritis.

Abstract: viral exanthems are a common problem in tropical regions, particularly affecting children. various skin rashes have been reported in acute infections caused by enterovirus. biological samples from a child who presented generalized rashes were sent to the enteric virus laboratory of the adolfo lutz institute for laboratory diagnosis to be performed. a viral sample isolated from rd (human rhabdomyosarcoma cells) was subjected to the polymerase chain reaction and showed a 437-base pair product that was characteristic of the enterovirus genus. echovirus 6 (e-6) serotype was identified using the indirect immunofluorescence test. in addition, paired serum samples presented seroconversion to e-6. so far, there have not been any reports of e-6 involvement in exanthematic diseases in brazil. thus, the importance of epidemiological surveillance for these diseases and their complications is emphasized.

Abstract: Undernutrition is one of the most important public health problems, affecting more than 900 million individuals around the World. It is responsible for the highest mortality rate in children and has long-lasting physiologic effects, including an increased susceptibility to fat accumulation mostly in the central region of the body, lower fat oxidation, lower resting and postprandial energy expenditure, insulin resistance in adulthood, hypertension, dyslipidaemia and a reduced capacity for manual work, among other impairments. Marked changes in the function of the autonomic nervous system have been described in undernourished experimental animals. Some of these effects seem to be epigenetic, passing on to the next generation. Undernutrition in children has been linked to poor mental development and school achievement as well as behavioural abnormalities. However, there is still a debate in the literature regarding whether some of these effects are permanent or reversible. Stunted children who had experienced catch-up growth had verbal vocabulary and quantitative test scores that did not differ from children who were not stunted. Children treated before 6 years of age in day-hospitals and who recovered in weight and height have normal body compositions, bone mineral densities and insulin production and sensitivity.
Cylindrospermopsin in Water Supply Reservoirs in Brazil Determined by Immunochemical and Molecular Methods  [PDF]

Journal of Water Resource and Protection (JWARP) , 2011, DOI: 10.4236/jwarp.2011.36044
Abstract: It is reported for the first time in Brazil and South America the presence of cylindrospermopsin (CYN) in water supply reservoirs. CYN is a powerful hepatotoxic alkaloid implicated in outbreaks of human sicknesses. We detected CYN in different sources of water in Northeastern Brazil using molecular and immunological techniques. The highest concentrations of toxin occurred in the Jucazinho reservoir with the phytoplankton containing the potentially CYN-producing C. raciborskii and Sphaerospermopsis aphanizomenoides (previously known as Aphanizomenon aphanizomenoides). The polyketide synthase (PKS) and peptide synthetase (PS), which are directly related to the ability to produce CYN, were found in all the analyzed samples. The result of the present study emphasizes the need to improve monitoring of CYN in water bodies used for drinking and recreation, in order to avoid exposure of human populations to this toxin.

Abstract: bacteria isolated from marine sponges found off the coast of rio de janeiro, brazil, were screened for the production of antimicrobial substances. we report a new pseudomonas putida strain (designated p. putida mm3) isolated from the sponge mycale microsigmatosa that produces a powerful antimicrobial substance active against multidrug-resistant bacteria. p. putida mm3 was identified on the basis of 16s rrna gene sequencing and phenotypic tests. molecular typing for mm3 was performed by rapd-pcr and comparison of the results to other pseudomonas strains. our results contribute to the search for new antimicrobial agents, an important strategy for developing alternative therapies to treat infections caused by multidrug-resistant bacteria.

Abstract: bloom's taxonomy was created in order to support the classification of educational objectives and facilitate the process of teaching, learning and the cognitive development. even though bloom's taxonomy has proven to be a significant tool for the process of teaching, learning, and assessment, few educators use it adequately, mostly because its use is not as clear as it should be. this paper describes the bloom's taxonomy including its updated version, and has the objective of clarifying some important points of how to bloom's taxonomy can be used in engineering courses (teaching, learning, and assessment) to provide an adequate, planed, and controlled cognitive development.

Pinto, Rosana do Carmo Novaes;Santana, Ana Paula;
Psicologia: Reflex?o e Crítica , 2009, DOI: 10.1590/S0102-79722009000300012
Abstract: the article discusses the semiology of aphasias, which started being developed in the 19th century by broca and wernicke. we do not provide an exhaustive list of symptoms and syndromes to address the theme, since we aim to critically discuss why the semiology of aphasias is still based mainly on organic perspectives in clinical practice and scientific research. we also discuss the contributions of luria and jakobson to a better understanding of how language is affected in aphasias and how modern linguistics, in special the discursive neurolinguistics, may enlighten the debate. we analyze some data to illustrate the theoretical and methodological assumptions of the above mentioned approaches and also discuss the excessive strength that classifications have in the clinical context.

Eccos Revista Científica , 2009,
Abstract: This paper proposes a reflection on the Law 10.639/03, given the lack of parliamentary debate on the significance of education in the construction of cultural and ethnic identity in Brazil. The objective is to confront the history teaching and Afro-Brazilian culture in the curriculum of elementary and secondary education as a strategy to fight for social inclusion of the black. The text contributes to clarify the positions of speech of the subjects involved in this debate and allows to contextualize the challenges in the production of public policies aimed at correcting social inequalities on the Brazilian scenario.
