Cariótipo, comportamento dos cromossomos na meiose e região organizadora de nucléolo de aranhas pertencentes às famílias Oxyopidae e theridiidae (Araneomorphae, entelegynae)

No presente trabalho, seis espécies de aranhas pertencentes às famílias Oxyopidae e Theridiidae foram examinadas citogeneticamente, através de técnicas de coloração convencional e impregnação pelo íon prata. A análise de células mitóticas e meióticas coradas com Giemsa de quatro espécies de Oxyopidae, Hamataliwa sp., Peucetia flava, Peucetia rubrolineata e Oxyopes salticus revelou informações citogenéticas inéditas para a família. Metáfases espermatogoniais de Hamataliwa sp. mostraram o cariótipo 2n=26+X1X2, o qual corresponde ao maior número diplóide já descrito para a família. Células mitóticas de P. flava e P. rubrolineata exibiram 2n♂=20+X1X2 e 2n♂=20+X, respectivamente, indicando a ocorrência de uma variabilidade cariotípica dentro desse gênero. Os cromossomos dessas três espécies apresentaram morfologia acro/telocêntrica. Os resultados obtidos em O. salticus foram surpreendentes, pois revelaram 2n♂=10+X, o menor número cromossômico encontrado para Oxyopidae e o segundo menor registrado para aranhas do grupo Entelegynae, bem como morfologia meta/submetacêntrica da maioria dos cromossomos. Além disso, um indivíduo da amostra de O. salticus examinada apresentou um heteromorfismo nos elementos que constituem o primeiro par do cariótipo e um cromossomo B em algumas células. Em Hamataliwa sp. e O. salticus, as regiões organizadoras de nucléolo estavam localizadas sobre dois e três pares autossômicos, respectivamente. Em relação às duas espécies de Theridiidae, Argyrodes elevatus apresentou um cariótipo totalmente discrepante, quando comparado com aqueles já descritos para a família, uma vez que mostrou o número diplóide 2n♂=21, sistema cromossômico sexual do tipo X/XX e morfologia cromossômica meta/submetacêntrica. No entanto, as características cariotípicas verificadas na maioria dos exemplares de Nesticodes rufipes foram semelhantes aquelas mais freqüentes em aranhas ...

A dinâmica do setor de serviços de saúde na região administrativa de Barretos

The dynamics of the health services sector can be seen in studies of geographical features as analysis on the quantity and quality of médical and hospital services provided and the demand or need sensed by the population, whether the public sector, whether private sector within a defined portion of space, in analysis in this study, the Administrative Region of Barretos, State of São Paulo. This study seeks to better understand the dynamics of the health services sector (Public and Private) in the production of urban space of the Administrative Region of Barretos, for it will be reviewed, in particular, the Cities Health Centers, Bebedouro and Barretos. Also proposes through this, try to clarify the central regional Barretos and Bebedouro in the context of health services

Estimativa das emissões de monóxido de carbono por veículos automotivos na cidade de Campinas/SP utilizando o modelo CAL3QHCR

Air pollution is an environmental issue worldwide and frequently cause negative effects on population health and ecosystems on cities. The relationship between climate and atmospheric pollution can be used as a surrogate to the intensity of air pollution. The present and quantity of some gases can be used as indicators to air quality: particulate matter (PM), sulfur dioxide (SO2), carbon monoxide (CO), ozone (O3), and nitrogen dioxide (NO2). Among those gases, CO has its major source within the cities, where automobiles are the main emitter. But measure pollutant concentration are challenging, sometimes because the lack of good equipments due to high costs and of the large variability of models that varies in precision, way of measure and distribution of sellers. Modeling are useful when there are an intend to evaluate air pollution, its sources and evaluate scenarios. This work aims to use CAL3QHCR model developed by the U.S Environmental Protection Agency (EPA) to generate predictive surfaces of CO concentration distribution on a site within Campinas city, located in São Paulo state, Brazil. CAL3QHCR model use data urban automobile circulation to generate spatial results for CO distribution. We observed that the pollution concentration was lower on our modeling than the concentrations measured by Companhia Ambiental do Estado de São Paulo (CETESB), the main environmental company on the São Paulo state. Also the correlation between average estimates of our model and the measure by CETESB was weak, indicating that the model used on this study need to be or better parameterized, or the scale we measured of CO emissions need to be rescaled. Although the model failed to correlate to CETESB data, maybe one that explore the estimated emissions distributed within the sites to understand spatial distributions of CO on the regions. Also, the generated information can also be used to other studies, and come to be useful to explain heat island

Indicadores Antropométricos do Estado Nutricional de Idosas Praticantes e Não Praticantes de Exercício Fisíco na Zona Norte de São José do Rio Preto-SP

Although the regular practice of physical exercise for the maintenance of the nutritional state and quality of life is important, it is not a common habit among the elderly, especially those of the lower income social bracket. The objective was to characterize and compare according to social-economic conditions and anthropometric indexes of the nutritional state of the elderly who regularly practice and those who do not practice exercises, offered at no cost, in the Northern zone of São José do Rio Preto-SP. In this study, 110 elderly women participated, of which 60 (group P) exercised regularly and 50 did not (group NP). Group P participated in a special gym program, free of charge, for at least 2 years, 2 to 3 times a week, one hour a day. Group NP was recruited from the same location as Group P. The comparison between the groups of elderly women was proportionately distributed according to marital status, level of education, means of locomotion, results of body mass index (IMC), waist to hip ratio (RCQ) and calf circumference, using the chi-square test. Comparisons were also made of average age, per capita family income, individual income, IMC, arm and triceps skin fold measured by t-Test. Differences were not found in all the comparisons made. The variables that stood out were the IMC (overweight) and RCQ (risk of chronic diseases) results, which were above what was expected, and the high frequency of walking and riding buses for both groups of elderly women (about 60%). We came to the conclusion that the low-intensity exercise program evaluated made no difference in the nutritional profile of the elderly who also used walking as a means of getting around.
