Abstract: anus neoplasm accounts for 2 to 4% of colorectal tumors, being more prevalent around the seventh and the eighth decades. females are mostly affected, and the ratio is 3:1. its increased prevalence amongst the population in the past years is probably related to the higher number of people that are affected by sexually transmitted diseases, mainly human papillomavirus (types 16 and 18, mostly) and/or the human immunodeficiency virus. diagnosis is based on clinical findings and anatomopathological tests. the treatment of choice is radiochemotherapy, and the rescue surgery with abdominoperineal resection is used for recurrence and persistence cases. a retrospective and prospective longitudinal observational study was performed with 11 patients diagnosed with anal neoplasm from 2004 to 2010. six (54.5%) were females and five (45.5%) were males. the incidence was higher in the sixth decade, at the mean age of 54.45 years. the most frequent histological type observed was the epidermoid carcinoma, and the most frequent cell differentiation type was the moderately differentiated. chemotharapy associated with radiotherapy was used in 81.9% of the patients, and abdominoperineal resection was necessary as a rescue surgery in 18.2% of the patients.

Abstract: this paper presents an analysis of the geochemistry of superficial waters in the itacolomi state park and their relationship to the geological scenario and soil geochemistry. thirty six soil samples were collected at points located in representative areas from the different lithologies. in each region, the soil samples were collected at diverse depths. in addition, eighteen water sampling points were also selected in areas with different drainage patterns. in the ground and water samples, the concentrations of major and trace elements were determined by icp-oes. also, physical-chemical parameters were determined for the water samples. the results reveal that geology plays an essential role in the chemical signature of the soils and superficial waters. comparison with standard values defined by the rules cetesb 195/05 and conama 357/05 proved the influence of pedological and geological characteristics on the water quality. anomalous concentrations of several elements were found in the water and ground samples. in addition, it was also possible to observe that the regulations for water quality of this area are inadequate since they do not take the geological factors into consideration.
Padr es espaciais e conserva o da diversidade de serpentes do bioma cerrado = Spatial patterns and biodiversity conservation of snakes from Cerrado biome

Acta Scientiarum : Biological Sciences , 2007,
Abstract: Em geral, as tentativas para estabelecer áreas prioritárias para conserva o no Cerrado têm sido baseadas em critérios subjetivos. No presente trabalho, foram utilizados dados macroecológicos de distribui o de 129 espécies de serpentes distribuídas em 181 células com 1o de latitude/longitude do Cerrado para analisar padr es espaciais na riqueza e propor uma estratégia de conserva o para essas espécies. Verificou-se que as cinco variáveis ambientaisanalisadas explicaram apenas 34,65% da varia o na riqueza de serpentes do Cerrado. Para sele o de áreas prioritárias utilizando-se procedimentos de otimiza o, estabeleceu-se que 14 células s o necessárias para representar todas as espécies pelo menos uma vez. Também foram incorporados ao modelo os padr es de ocupa o humana no Cerrado, visando minimizar conflitos entre desenvolvimento e conserva o, e neste caso as células concentram-se principalmente nosudoeste do bioma. Em fun o da falta geral de conhecimento sobre os padr es mais locais de distribui o de espécies no Cerrado, esses resultados devem ser considerados preliminares. De qualquer modo, o presente estudo, em escala biogeográfica, é importante para estabelecer estratégias metodológicas e para fornecer uma vis o ampla dos padr es de diversidade e de que regi es seriam mais importantes para sua conserva o. Until recently, the conservation of Cerrado has been neglected andattempts to establish conservation priorities were usually based on subjective criteria. In this paper, macroecological data of distribution of 129 species of snakes in the Cerrado were used to evaluate spatial patterns in species richness and to establish a system of potential areas that preserves all snake species in the region. The five environment variables used as predictors explained only 34.65% of the variance in species richness. In order to establishconservation priorities, optimization procedures were used. These procedures showed that 14 cells must be selected to represent all species at least once. Incorporating in the model the human occupation in Cerrado, a northward shift in selected cells is observed, allowing minimizing potential conservation-human development conflicts. These results must be considered preliminary and more detailed studies are necessary to evaluate the spatialpatterns in snakes’ richness of Cerrado, considering the lack of knowledge on distribution and taxonomy of these species at local scales. However, the conservation biogeography approach used here is a first step towards understanding the overall diversity patterns and to establish the be

Abstract:

Aqueous roots extract of Alchornea cordifolia was studied to evaluate its traditional antifertility claim. Antifertility effect of Alchornea cordifolia was evaluated according to the stages of pregnancy of female rats. In the first stage, forty female rats were randomly divided into four groups (10 rats/group) and respectively treated with 1 ml distilled water (control), 100, 200 and 400 mg/kg body weight (BW) per day of Alchornea cordifolia. After laparotomy and at parturition, sites of implantation and resorption on the uterine horns were determined. The ovaries and uterus were collected and weighed. Blood samples were collected for hormonal assay. In the second and third stage of pregnancy, treatment schedule and antifertility parameters were assessed as above for the first stage. Treated groups received daily 400 mg/kg bw of extract of Alchornea cordifolia while Control group received distilled water. It was observed in the first stage of pregnancy that, the number of resorption sites significantly (p < 0.05) decreased at 100 and 200 mg/kg. No implantation site was observed at dose 400 mg/kg after laparotomy as well as the number of pups at parturition at all doses. The body weight of ovaries and uterine horns at dose 400 mg/kg significantly (p < 0.05) decreased when compared to the control. The extract dose dependently decreased significantly the concentrations of serum progesterone. In the second stage of pregnancy after laparotomy and at parturition, the number of

Abstract: the environmental pollution observed down through the years in the streams of manaus, linked to the process of social degradation on the populations which live in these areas was the motive for conceiving prosamim - programa social e ambiental dos igarapés de manaus. the program seeks the environmental recuperation of streams and the social improvement of families that live a risk situation on the stream banks. the main target of this research consists in the economical evaluation of environmental benefits perceived by the population in the educandos basin proceeding from prosamim, using the contingent valuation method - cvm to estimate individual willingness to pay for the environmental improvement. we estimated a sample size corresponding to 1,070 questionnaires, taking into account an error of 3% and significance level of 5%. in accordance with the results obtained, we concluded that the people were willing to pay r$ 13.73 per month toward implementing the prosamim, for an annual total of r$46,325,074.92 per year. analyzing the influence of socioeconomic variables on the acceptance probability of paying for environmental benefits, we concluded that the probability was greater among those with a higher income. we also concluded that, the actions of prosamim have generated significant improvements for the population of manaus from the environmental as well as the social point of view.

Agamenon R. E. Oliveira
Advances in Historical Studies (AHS) , 2013, DOI: 10.4236/ahs.2013.23016
Abstract: In the first and second parts of his masterpiece, Analytical Mechanics, dedicated to static and dynamics respectively, Lagrange (1736-1813) describes in detail the development of both branches of mechanics from a historical point of view. In this paper this important contribution of Lagrange (Lagrange, 1989) to the history of mechanics is presented and discussed in tribute to the bicentennial year of his death.
History of Two Fundamental Principles of Physics: Least Action and Conservation of Energy  [PDF]
Agamenon R. E. Oliveira
Advances in Historical Studies (AHS) , 2014, DOI: 10.4236/ahs.2014.32008
Abstract: One of the aims most sought after by physics along the years has been to find a principle, the simplest possible, into which all natural phenomena would fit, and which would also allow the calculation of all past occurrences and principally future occurrences. Evidently, this is far from being reached and quite probably does not even exist. Nevertheless, an approximation to this ideal is always possible and the history of physics shows that some results in this direction have been achieved. Thus, the history of the principles of least action and conservation of energy presented in this paper explains the search for this ideal.
