Ichthyofauna of Rio Jurubatuba, Santos, São Paulo: a high diversity refuge in impacted lands

Ichthyofaunistic surveys in the Atlantic Rainforest have been published in relatively few works, in spite of the major biological importance of this once vast biome which is rapidly vanishing due to disordered human population growth and natural resources overexploitation. The present study aimed to access the fish fauna of a relatively well preserved basin between the cities of Santos and Cubatão (SP), an area highly modified by human activities where recent ichthyofaunistic surveys are still missing. Collections were made during three field trips in Rio Jurubatuba, a medium sized costal river, and Riacho Sabão, one of its main tributaries. A total of 2773 specimens were sampled, representing 25 species from 14 families. Six species were primary marine using the upper reaches of Rio Jurubatuba. Twelve of the 19 freshwater species are endemic of the Atlantic Rainforest and four are present in regional lists of endangered species. Only five species occurred in both Rio Jurubatuba and Riacho Sabão. The most diverse family was Characidae, followed by Poeciliidae, Rivulidae and Heptapteridae. Phalloceros caudimaculatus was the most abundant species, followed by Poecilia vivipara and Geophagus brasiliensis. The study area is considered well preserved and due to its critical location, urges for conservation policies to protect its fish diversity.

Phlebotomines (Diptera, Psychodidae) in the Speleological Province of the Ribeira Valley: 2. Parque Estadual do Alto Ribeira (PETAR), São Paulo State, Brazil

The Parque Estadual do Alto Ribeira (PETAR) with about 250 caves, in an Atlantic forest reserve, is an important ecotourist attraction in the Ribeira Valley, an endemic area of American cutaneous leishmaniasis (ACL). With the purpose of investigating Leishmania vector species bothersome to humans the sandfly fauna was identified and some of its ecological aspects in the Santana nucleus, captures were undertaken monthly with automatic light traps in 11 ecotopes, including caves, forests, a camping site and domiciliary environments, and on black and white Shannon traps, from January/2001 to December/2002. A total of 2,449 sandflies representing 21 species were captured. The highest values of abundance obtained in the captures with automatic light traps were for Psathyromyia pascalei and Psychodopygus ayrozai. A total of 107 specimens representing 13 species were captured on black (12 species) and white (6 species) Shannon traps set simultaneously. Psychodopygus geniculatus females predominated on the black (43.75%), and Psathyromyia lanei and Ps. ayrozai equally (32.4%) on the white. Nyssomyia intermedia and Nyssomyia neivai, both implicated in the transmission of ACL in the Brazilian Southeastern region, were also captured. Ny. intermedia predominated in the open camping area. Low frequencies of phlebotomines were observed in the caves, where Evandromyia edwardsi predominated Lutzomyia longipalpis, the main vector of the American visceral leishmaniasis, was aslo present. This is its most southernly reported occurrence in the Atlantic forest.

Prevalência de diagnóstico auto-referido de osteoporose, Brasil, 2006

OBJETIVO: Estimar a prevalência de osteoporose auto-referida (com diagnóstico médico prévio) e de fatores de risco e proteção associados. MÉTODOS: Estudo transversal baseado em dados do sistema de Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico (VIGITEL). Foram entrevistados 54.369 indivíduos com idade >18 anos residentes em domicílios servidos por pelo menos uma linha telefônica fixa nas capitais brasileiras e Distrito Federal em 2006. Estimativas de osteoporose segundo fatores socioeconômicos, comportamentais e índice de massa corporal foram estratificadas por sexo. Foram calculados riscos de ocorrência de osteoporose para cada variável individualmente, e em modelo multivariado, considerando-se odds ratio como proxy da razão de prevalência. RESULTADOS: A prevalência de osteoporose referida foi de 4,4%, predominantemente entre mulheres (7,0%), com idade >45 anos, estado civil não solteiro e ex-fumante. Entre homens, ter mais de 65 anos, ser casado ou viúvo e sedentário associaram-se positivamente ao desfecho. CONCLUSÕES: Dentre os fatores associados à osteoporose, destacam-se aspectos modificáveis relacionados com a prevenção da doença, como a atividade física e tabagismo.

Epidemiology of leisure, transportation, occupational, and household physical activity: prevalence and associated factors

Background: To estimate the prevalence of and identify factors associated with physical activity in leisure, transportation, occupational, and household settings. Methods: This was a cross-sectional study aimed at investigating living and health conditions among the population of São Paulo, Brazil. Data on 1318 adults aged 18 to 65 years were used. To assess physical activity, the long version of the International Physical Activity Questionnaire was applied. Multivariate analysis was conducted using a hierarchical model. Results: The greatest prevalence of insufficient activity related to transportation (91.7%), followed by leisure (77.5%), occupational (68.9%), and household settings (56.7%). The variables associated with insufficient levels of physical activity in leisure were female sex, older age, low education level, nonwhite skin color, smoking, and self-reported poor health; in occupational settings were female sex, white skin color, high education level, self-reported poor health, nonsmoking, and obesity; in transportation settings were female sex; and in household settings, with male sex, separated, or widowed status and high education level. Conclusion: Physical activity in transportation and leisure settings should be encouraged. This study will serve as a reference point in monitoring different types of physical activities and implementing public physical activity policies in developing countries

Ocorrência de Panstrongylus guentheri Berg (Hemiptera: Reduviidae) no Mato Grosso do Sul

Relata-se a primeira ocorrência de Panstrongylus guentheri Berg no Brasil. Essa espécie, até então, havia sido observada somente na Argentina, Paraguai, Bolívia e Uruguai. Desta feita, amplia-se a distribuição geográfica desse Triatominae por meio de dois exemplares capturados nos municípios de Bodoquena e Itaporã, ambos no Mato Grosso do Sul. Esses exemplares estavam em ambiente intradomiciliar

Conhecimento contraceptivo no puerpério precoce e seu uso efetivo após seis meses

Objetivo: Avaliar o conhecimento sobre métodos anticoncepcionais em mulheres no puerpério, bem como analisar a escolha e seu uso efetivo decorrido seis meses do parto. Método: Estudo prospectivo, transversal, realizado por entrevistas no puerpério precoce e após seis meses, com 107 mulheres internadas que aceitaram participar do estudo após a leitura do consentimento livre e esclarecido. Avaliaram-se os indicadores socioeconômicos, o conhecimento em anticoncepção, a orientação recebida, a oferta e uso de contraceptivos após seis meses do parto. Resultados: Os métodos anticoncepcionais mais conhecidos de forma espontânea foram a pílula (89%) e o condom masculino (65%). O DIU com hormônio foi o menos lembrado espontaneamente. Perto de 95% das puérperas referiram desejar evitar nova gravidez. Os métodos mais escolhidos foram a pílula (24%) e a ligadura tubária (18%). Ao se perguntar sobre o interesse em outros métodos contraceptivos após o questionário, 48% demonstraram interesse, sendo o mais citado o DIU (26%). Apenas um quarto das mulheres que disseram conhecer o DIU, faria a opção pelo método. Após seis meses, apenas 47 mulheres foram contatadas, e somente 31 delas haviam recebido orientação sobre anticoncepção (em média sobre três métodos diferentes). Houve apenas uma inserção de DIU de cobre, e três mulheres estavam grávidas naquele momento. Conclusões: O conhecimento da anticoncepção pelas mulheres no puerpério foi alto e melhorou após a estimulação. A avaliação dos resultados parece indicar que a simples leitura dos métodos anticoncepcionais disponíveis contribui para a escolha por métodos não relatados espontaneamente

Interleukin-22 forms dimers that are recognized by two interleukin-22R1 receptor chains

Interleukin-22 (IL-22) is a class 2 cytokine whose primary structure is similar to that of interleukin 10 (IL-10) and interferon-gamma (IFN-gamma). IL-22 induction during acute phase immune response indicates its involvement in mechanisms of inflammation. Structurally different from IL-10 and a number of other members of IL-10 family, which form intertwined inseparable V-shaped dimers of two identical polypeptide chains, a single polypeptide chain of IL-22 folds on itself in a relatively globular structure. Here we present evidence, based on native gel electrophoresis, glutaraldehyde cross-linking, dynamic light scattering, and small angle x-ray scattering experiments, that human IL-22 forms dimers and tetramers in solution under protein concentrations assessable by these experiments. Unexpectedly, low-resolution molecular shape of IL-22 dimers is strikingly similar to that of IL-10 and other intertwined cytokine dimeric forms. Furthermore, we determine an ab initio molecular shape of the IL-22/IL-22R1 complex which reveals the V-shaped IL-22 dimer interacting with two cognate IL-22R1 molecules. Based on this collective evidence, we argue that dimerization might be a common mechanism of all class 2 cytokines for the molecular recognition with their respective membrane receptor. We also speculate that the IL-22 tetramer formation could represent a way to store the cytokine in nonactive form at high concentrations that could be readily converted into functionally active monomers and dimers upon interaction with the cognate cellular receptors.

Influence of metallic nanoparticles on electric-dipole and magnetic-dipole transitions of Eu(3+) doped germanate glasses

Luminescence properties of Eu(3+) doped germanate glasses containing either silver or gold nanoparticles (NPs) were investigated for excitation at 405 nm. Enhanced emissions and luminescence quenching of the Eu(3+) transitions in the range from 570 to 720 nm were observed for samples having various concentrations of metallic NPs. Electric-dipole and magnetic-dipole transitions that originate from the Eu(3+) level (5)D(0) exhibit large enhancement due to the presence of the metallic NPs. The results suggest that the magnetic response of rare-earth doped metal-dielectric composites at optical frequencies can be as strong as their electric response due to the confinement of the optical magnetic field.

Genetic trend estimates of meat quality traits in a male broiler line

The present research was conducted to estimate the genetic trends for meat quality traits in a male broiler line. The traits analyzed were initial pH, pH at 6 h after slaughter, final pH, initial range of falling pH, final range of falling pH, lightness, redness, yellowness, weep loss, drip loss, shrink loss, and shear force. The number of observations varied between 618 and 2125 for each trait. Genetic values were obtained by restricted maximum likelihood, and the numerator relationship matrix had 107,154 animals. The genetic trends were estimated by regression of the broiler average genetic values with respect to unit of time (generations), and the average genetic trend was estimated by regression coefficients. Generally, for the traits analyzed, small genetic trends were obtained, except for drip loss and shear force, which were higher. The small magnitude of the trends found could be a consequence of the absence of selection for meat quality traits in the line analyzed. The estimates of genetic trends obtained were an indication of an improvement in the meat quality traits in the line analyzed, except for drip loss.

Defects in vesicle core induced by Escherichia coli dihydroorotate dehydrogenase

Dihydroorotate dehydrogenase (DHODH) catalyzes the oxidation of dihydroorotate to orotate during the fourth step of the de novo pyrimidine synthesis pathway. In rapidly proliferating mammalian cells, pyrimidine salvage pathway is insufficient to overcome deficiencies in that pathway for nucleotide synthesis. Moreover, as certain parasites lack salvage enzymes, relying solely on the de novo pathway, DHODH inhibition has turned out as an efficient way to block pyrimidine biosynthesis. Escherichia coli DHODH (EcDHODH) is a class 2 DHODH, found associated to cytosolic membranes through an N-terminal extension. We used electronic spin resonance (ESR) to study the interaction of EcDHODH with vesicles of 1,2-dioleoyl-sn-glycero-phosphatidylcholine/detergent. Changes in vesicle dynamic structure induced by the enzyme were monitored via spin labels located at different positions of phospholipid derivatives. Two-component ESR spectra are obtained for labels 5- and 1 0-phosphatidylcholine in presence of EcDHODH, whereas other probes show a single-component spectrum. The appearance of an additional spectral component with features related to fast-motion regime of the probe is attributed to the formation of a defect-like structure in the membrane hydrophobic region. This is probably the mechanism used by the protein to capture quinones used as electron acceptors during catalysis. The use of specific spectral simulation routines allows us to characterize the ESR spectra in terms of changes in polarity and mobility around the spin-labeled phospholipids. We believe this is the first report of direct evidences concerning the binding of class 2 DHODH to membrane systems.

Dez anos de parâmetros curriculares nacionais: a prática da Educação Física na visão dos seus autores

The study checked possible theory-methodologic assumptions into Physical Education PCNs by the teachers of the last years of elementary school. The analyses in the publishing allow us to identify the different didactic procedures when compared with those which set up the traditional expectations. From these elements and using the projective method, it was developed an interview with focal group. The data obtained showed us docent perceptions which rearrange the educative practice, and interpretation allows us to realize which of the teachers views approaches the propositions in the official document, even if no reference has been done to it.

The variability and predictors of quality of AIDS care services in Brazil

Background: Since establishing universal free access to antiretroviral therapy in 1996, the Brazilian Health System has increased the number of centers providing HIV/AIDS outpatient care from 33 to 540. There had been no formal monitoring of the quality of these services until a survey of 336 AIDS health centers across 7 Brazilian states was undertaken in 2002. Managers of the services were asked to assess their clinics according to parameters of service inputs and service delivery processes. This report analyzes the survey results and identifies predictors of the overall quality of service delivery. Methods: The survey involved completion of a multiple-choice questionnaire comprising 107 parameters of service inputs and processes of delivering care, with responses assessed according to their likely impact on service quality using a 3-point scale. K-means clustering was used to group these services according to their scored responses. Logistic regression analysis was performed to identify predictors of high service quality. Results: The questionnaire was completed by 95.8% (322) of the managers of the sites surveyed. Most sites scored about 50% of the benchmark expectation. K-means clustering analysis identified four quality levels within which services could be grouped: 76 services (24%) were classed as level 1 (best), 53 (16%) as level 2 (medium), 113 (35%) as level 3 (poor), and 80 (25%) as level 4 (very poor). Parameters of service delivery processes were more important than those relating to service inputs for determining the quality classification. Predictors of quality services included larger care sites, specialization for HIV/AIDS, and location within large municipalities. Conclusion: The survey demonstrated highly variable levels of HIV/AIDS service quality across the sites. Many sites were found to have deficiencies in the processes of service delivery processes that could benefit from quality improvement initiatives. These findings could have implications for how HIV/AIDS services are planned in Brazil to achieve quality standards, such as for where service sites should be located, their size and staffing requirements. A set of service delivery indicators has been identified that could be used for routine monitoring of HIV/AIDS service delivery for HIV/AIDS in Brazil (and potentially in other similar settings).

Genetic Diversity on the Integrase Region of the pol Gene among HIV Type 1-Infected Patients Naive for Integrase Inhibitors in Sao Paulo City, Brazil

The presence of mutations associated with integrase inhibitor (INI) resistance among INI-naive patients may play an important clinical role in the use of those drugs Samples from 76 HIV-1-infected subjects naive to INIs were submitted to direct sequencing. No differences were found between naive (25%) subjects and subjects on HAART (75%). No primary mutation associated with raltegravir or elvitegravir resistance was found. However, 78% of sequences showed at least one accessory mutation associated with resistance. The analysis of the 76 IN sequences showed a high polymorphic level on this region among Brazilian HIV-1-infected subjects, including a high prevalence of aa substitutions related to INI resistance. The impact of these findings remains unclear and further studies are necessary to address these questions.
