Health and life quality can be preserved and improved by the regular practice of physical activity. Sedentarism is an undesirable condition and represents risk for the health. This study has as objective to analyze the caloric cost and the basic physical qualities in college students of different technical levels. The research was descriptive and applied to 35 students, volunteers, from 19 to 34 years old, from both sexes, participants of the Dance Body of State University of Piau, in the city of Teresina, in the activities of folkloric dance and walking. The caloric cost was evaluated with the accelerometer Caltrac 100/100 Plan, the basic physical qualities through the sitting and reaching test (flexibility); the vertical impulsion test, crouch (inferior members strength); the abdominal test (located muscular resistance); and the Burpee test (motor coordination). The participants were separated in two groups according to their time of practice: group 1 (beginners), group 2 (advanced). The parametric tests t by Student and correlation by Pearson were used, observing a significance p<0,05 in the sense of comparing the observed results, which showed that there are no significant differences between the two groups of students, according to the time of practice, in which concerns the caloric cost. The results of Strength, Resistance and Co-ordination test did not differ so much between the two groups. On the other hand, in the variable flexibility significant differences were observed (sig.p = 0,0022 << 0,05) between the observed groups, being Group 1 (31,5 6,3) meaningfully less than Group 2 (38,1 4,9), which constitutes a difference of about 21%. Such results present relations of caloric cost compensation between the studied groups, the motivation to the beginners group and flexibility to tne advanced group, justifying the lack of significant distinctions. In this sense the folkloric dance, as a physical activity, appears to be efficient, for significant co-relations are still noticed between the caloric cost levels of the dance with the walking, besides not presenting expressive differences between them.

Trypanosoma cruzi infection was evaluated in 390 resident individuals in different rural communities of Caic municipality, State of Rio Grande do Norte (RN). Of 28 investigated communities the soroprevalence of T. cruzi infection was 2.8% in eight rural communities individuals. The epidemiological characteristics of seropositive shown that the age ranged from 22 to 64 years, being significantly raised from 31 years (90.9%). The female gender was predominant and low education degree. Those individuals reported that they never donated blood, but they had direct contact with triatomines bug. The isolation of the parasite was performed by blood culture and xenoculture methods to determine the genetic variability of the samples. Twenty seven T. cruzi isolates were analyzed by RAPD as genetic marker using three random primers (M13-40, gt11-F and L15996). The T. cruzi isolates showed 73.7% of shared bands considering the average obtained with the three primers, and were genetically well correlated. Using this marker it was possible to separate the populations of the parasite in three distinct groups. The first group composed by isolates obtained of triatomines and humans from four different districts (Caic, Carabas, Serra Negra doNorte and Governador Dix-Sept Rosado); the second contained isolates obtained of triatomines of two different species (T. brasiliensis and P. lutzi) captured in Carabas and Serra Negra do Norte. The third grouped isolates obtained from humans of Angicos and Caic municipalities. In different localities of distinct mesoregions, State of RN, a profile genetic well correlated was identified among all isolates and the presence of three distinct groups of the parasite circulating among vertebrate and invertebrate hosts

Goat breeding in the state of Rio Grande do Norte, Brazil has promising economic possibilities, with the proper handling of the natural resources. The introduction of specialized animals has been one of the ways used to improve herd genetics and increase productivity. However, climate has been one of the regional factors that most interferes with the adaptation of the new genetic prevalence resulting from the introduction of exotic breeds, because in their country of origin, the air temperature during most of the year is lower than the animals body temperature. With this in mind, the aim of this study was to characterize behavioral, physiological and morphological profiles and milk production of female Saanen goats belonging to different genetic groups raised in the semi-arid region of Rio Grande do Norte in Northeast Brazil. The study was conducted in the city of Lages (5 42 00 S and 36 14 41 W). We used 25 lactating female Saanen goats, distributed into 3 genetic groups: 5 purebred animals, 11 three-quarter bred and 9 half-bred. Behavioral observations were made over three consecutive days in the months of August and September, between 09:00 and 11:30h, when the animals were grazing. Physiological and meteorological data were recorded in the last three days of June, July, August and September at 05:00h and at 16:00h. In the semi-intensive breeding system, the animals from different genetic groups were similar in both field behavior and physiological response patterns. Although the purebred goats had longer hair, they did not show symptoms of thermal discomfort. Their white hair helped to reflect the short wavelength rays and thus eliminate those at the longer wave lengths. We concluded that the animals raised in the semi-intensive milk production system in this study seem to have adapted to the climatic conditions of the semi-arid region of Rio Grande do Norte, Brazil

O uso intensivo de reas do Cerrado para produo agropecuria aliado ao manejo inadequado tem causado degradao dos solos. Nesse sentido h necessidade da incorporao de sistemas sustentveis como plantio direto e a integrao lavoura-pecuria. Este trabalho objetivou identificar o efeito da sucesso de milho+forrageiras e soja nos atributos fsicos do solo. Para tanto foi realizado, em rea experimental da Unesp, campus de Ilha Solteira, um ensaio composto do consrcio de milho com quatro forrageiras (Brachiaria brizantha,B. ruziziensis, Panicum maximum cv. Tanznia e P. maximum cv. ries) semeadas em trs modalidades (na linha de semeadura do milho misturada ao adubo, a lano simultnea semeadura do milho e a lano no estdio V4 do milho) e o milho sem consorciao (testemunha). A soja de vero foi implantada sobre os restos culturais dos tratamentos anteriores. Foram realizadas coletas para determinar a macro e microporosidade, porosidade total e densidade do solo em duas pocas de amostragem, aps as colheitas do milho e da soja. Pelos resultados, pde-se concluir que, em regies de cerrados, a sucesso de culturas utilizada promoveu a melhoria da macroporosidade, porosidade total e densidade do solo, independentemente da utilizao de forrageiras em consrcio com milho.

The perfect spatial intervention to manage the cultivation of the land, deriving from specific regions of the soil mapping, increases the agricultural productivity, as well as its clear gain. The relationships, spatial and Pearson, between eucalyptus data plant with some physical and chemical attributes of soil, in the growing season of 2011, in Selviria County, Mato Grosso do Sul State, Brazil (20 degrees 20' S lat.; 51 degrees 24' W long.), were studied in order to obtain the one that could have the best relationship in order to improve the wood productivity. Thus, a geostatistical grid was installed for the soil and plant data collection, it contained 120 sample points, in plantation of Eucalyptus camaldulensis of 2 years old. The soil was a Dystrophic Red Latosol (Haplic Acrustox) whit slope of 0.025m m(-1). Due to their excellent relationship with wood productivity, the basis diameter of the crown and the bulk density showed management specific regions of soil whit high relation to eucalyptus wood productivity.
Analysis of systemic inflammatory response in the carcinogenic process of uterine cervical neoplasia
Resumo:
The inflammatory response is an active process in cervical cancer and may act in the progression and/or regression of the lesion. At the site of inflammation, macrophages and neutrophils are present as well as cytokines such as TNF-alpha and IFN-gamma. This study aims to evaluate the inflammatory response levels in women with cervical intraepithelial lesions (CIN) and with squamous cell carcinoma (SCC) of the cervix. Serum samples obtained from women without evidence of disease (n = 30), with CIN (n = 30) and with SCC of the cervix (n = 30) were analyzed for the activities of N-acetylglucosaminidase (NAG) and myeloperoxidase (MPO) by enzymatic assay and the serum levels of TNF-alpha and IFN-gamma by ELISA assay. The activities of NAG and MPO and the level of TNF-alpha were higher in women with CIN compared to the women with SCC. The levels of IFN-gamma were lower in the group of women with CIN compared to the group with SCC. There was not a significant association between the degree of the CIN and the staging of the SCC of the cervix and the degree of inflammation as assessed by the levels of inflammatory markers. The inflammatory response was inversely correlated with the progression of the carcinogenic process. In the three groups, the control group, women with CIN and women with invasive SCC, there was no association between the degree of preinvasive lesions and staging of the SCC of the cervix.

Objetivando analisar as indicaes de profilaxia antirrbica humana no Municpio de Jaboticabal-SP, foi realizado um estudo retrospectivo descritivo no perodo de 2000 a 2006, com levantamento de dados registrados nas fichas de investigao de atendimento e clculo do custo com as vacinas destinadas profilaxia ps-exposio. Constatou-se que 2.493 pessoas agredidas por animais foram submetidas profilaxia com uso de vacina, num total de 7.108 doses e um custo de R$ 179.105,14. da totalidade de casos notificados, 2.184 (71,5 %) foram causados por ces e gatos clinicamente sadios no momento da agresso e que assim se mantiveram durante o perodo de observao, a qual foi feita pela prpria vtima ou pelo dono do animal. Considerando este fato e tambm a situao epidemiolgica da raiva no Municpio, pode-se inferir que essas vtimas poderiam ter sido dispensadas da profilaxia; entretanto, apenas 464 o foram, ou seja, 1.720 pessoas podem ter recebido vacina sem necessidade, ou seja 4.590 doses a um custo de R$ 114.420,81. em comparao com os nmeros de outros municpios do Estado de So Paulo e com a mdia nacional, constata-se que o nmero de profilaxias ps-exposio contra raiva muito alto em Jaboticabal, evidenciando que na conduta no se considerou o estado do agressor e a condio do Municpio de rea controlada para raiva. Recomenda-se conscientizao e capacitao permanentes das equipes de sade pblica quanto epidemiologia da doena e necessidade de observao adequada do animal agressor. essencial a integrao dos servios mdicos e veterinrios no atendimento s vitimas, visando uma melhor avaliao do caso para que a deciso de se instituir ou no a profilaxia ps-exposio seja feita com critrio e segurana.

The Lower Permian sphenopsids Phyllotheca australis Brongniart, 1828, Stephanophyllites sanpaulensis Millan & Dolianiti, 1980a and Paracalamites australis Rigby, 1966b, from the Toca do ndio outcrop in Cerquilho Municipality (northeastern Paran Basin, Tubar Supergroup) are redescribed on the basis of newly collected specimens. Some aspects, such as the leafsheath opening angles of the whorls and the foliar transverse to oblique striae or wrinkles, are discussed in detail. Phyllotheca australis and Paracalamites australis are widespread in Gondwana and have no particular stratigraphic or phylogenetic value. Otherwise, the genus Stephanophyllites, although only found in the Paran Basin and probably in Argentina (Bajo de Vliz Formation, close to the Carboniferous-Permian limit), can have a greater importance on account of some Raniganjia-like characters superimposed to a gross Phyllotheca-like morphology.

This study was undertaken to investigate the expression of p53, Ki-67, and CD31 proteins in endometrial polyps of postmenopausal women treated with tamoxifen (TAM). Postmenopausal women with endometrial polyps treated with TAM (n = 20), postmenopausal women with endometrial polyps without hormone use (n = 20), postmenopausal women with atrophic endometrium (n = 20), and postmenopausal women with endometrial adenocarcinoma (n = 20) were prospectively investigated. Tissue samples were immunohistochemically evaluated by monoclonal antibodies for p53, Ki-67, and CD31. The data were analyzed using the Student t test, analysis of variance, and 2 to evaluate significant differences between the groups. The level of significance was set at P < 0.05. There was no difference in the expression of p53 between the groups (P = 0.067). The expression of Ki-67 was higher in the polyp samples from TAM-treated women compared with those from the women using no hormone (P = 0.0047) and those from the women with atrophic endometrium (P = 0.008). Samples from the women with endometrial cancer was associated with higher Ki-67 expression compared with the polyp samples from TAM-treated women (P = 0.004). The expression of CD31 was higher in the polyp samples of TAM-treated women compared with that of the samples from the women with atrophic endometrium (P < 0.001) and similar to the polyp samples from the women using no hormone (P = 0.319) and to the samples from the women with endometrial cancer (P = 0.418). The use of TAM in postmenopausal women might be associated with increased cellular proliferation in endometrial polyps without interfering angiogenesis or inactivation of tumor suppressor proteins.
