Aborto

Esta monografia teve por objetivo fazer um levantamento bibliográfico sobre o aborto segundo o Código Penal Brasileiro,discorrendo sobre o assunto e suas controvérsias, utilizando os artigos 124,125,126,127 e 128 do Código Penal, como também a Constituição Federal, mostrando as várias mudanças ocorridas na história, o que influenciou em cada época a maneira como era tratado tal assunto.O ponto de vista de algumas religiões foram abordados, mostrando como cada uma encara tal assunto.Pode- se observar que o aborto não envolve apenas aspectos jurídicos, como também social, religioso, psicológico etc,o que o torna polêmico e abrangente.Na maioria das vezes, sendo feito com métodos e substâncias precárias e perigosas, como é mostrado neste trabalho e também as consequências que podem ser ocasionadas por estes métodos.Podendo com este estudo concluir que para que se comece haver uma solução a este respeito, deverá primeiramente tratar dos aspectos sociais, não adiantando apenas a lei garantir o nascimento de um ser e não fazer valer seus outros direitos fundamentais.Depois, ou a leu pune rigorosamente aqueles que cometem o delito, para assim intimidar as práticas clandestinas, pois na prática isso não ocorre, dificilmente se pune alguém por aborto, ou legaliza, para que assim pelo menos seja feito com estrutura, não ocorrendo tantas mortes e complicações pelas mulheres que o fazem.

Swimming Training in Rats Increases Cardiac MicroRNA-126 Expression and Angiogenesis

DA SILVA, N. D. JR, T. FERNANDES, U. P. R. SOCI, A. W. A. MONTEIRO, M. I. PHILLIPS, and E. M. DE OLIVEIRA. Swimming Training in Rats Increases Cardiac MicroRNA-126 Expression and Angiogenesis. Med. Sci. Sports Exerc., Vol. 44, No. 8, pp. 1453-1462, 2012. Purpose: MicroRNA (miRNA)-126 is angiogenic and has two validated targets: Sprouty-related protein 1 (Spred-1) and phosphoinositol-3 kinase regulatory subunit 2 (PI3KR2), negative regulators of angiogenesis by VEGF pathway inhibition. We investigated the role of swimming training on cardiac miRNA-126 expression related to angiogenesis. Methods: Female Wistar rats were assigned to three groups: sedentary (S), training 1 (T1, moderate volume), and training 2 (T2, high volume). T1 consisted of 60 min.d(-1) of swimming, five times per week for 10 wk with 5% body overload. T2 consisted of the same protocol of T1 until the eighth week; in the ninth week, rats trained for two times a day, and in the 10th week, rats trained for three times a day. MiRNA and PI3KR2 gene expression analysis was performed by real-time polymerase chain reaction in heart muscle. We assessed markers of training, the cardiac capillary-fiber ratio, cardiac protein expression of VEGF, Spred-1, Raf-1/ERK 1/2, and PI3K/Akt/eNOS. Results: The cardiac capillary-fiber ratio increased in T1 (58%) and T2 (101%) compared with S. VEGF protein expression was increased 42% in T1 and 108% in T2. Cardiac miRNA-126 expression increased 26% (T1) and 42% (T2) compared with S, correlated with angiogenesis. The miRNA-126 target Spred-1 protein level decreased 41% (T1) and 39% (T2), which consequently favored an increase in angiogenic signaling pathway Raf-1/ERK 1/2. On the other hand, the gene expression of PI3KR2, the other miRNA-126 target, was reduced 39% (T1) and 78% (T2), and there was an increase in protein expression of components of the PI3K/Akt/eNOS signaling pathway in the trained groups. Conclusions: This study showed that aerobic training promotes an increase in the expression of miRNA-126 and that this may be related to exercise-induced cardiac angiogenesis, by indirect regulation of the VEGF pathway and direct regulation of its targets that converged in an increase in angiogenic pathways, such as MAPK and PI3K/Akt/eNOS.

Effects of elevation and land use on the biomass of trees, shrubs and herbs at Mount Kilimanjaro

The protection and sustainable management of forest carbon stocks, particularly in the tropics, is a key factor in the mitigation of global change effects. However, our knowledge of how land use and elevation affect carbon stocks in tropical ecosystems is very limited. We compared aboveground biomass of trees, shrubs and herbs for eleven natural and human-influenced habitat types occurring over a wide elevation gradient (866–4550 m) at the world's highest solitary mountain, Mount Kilimanjaro. Thanks to the enormous elevation gradient, we covered important natural habitat types, e.g., savanna woodlands, montane rainforest and afro-alpine vegetation, as well as important land-use types such as maize fields, grasslands, traditional home gardens, coffee plantations and selectively logged forest. To assess tree and shrub biomass with pantropical allometric equations, we measured tree height, diameter at breast height and wood density and to assess herbaceous biomass, we sampled destructively. Among natural habitats, tree biomass was highest at intermediate elevation in the montane zone (340 Mg ha−1), shrub biomass declined linearly from 7 Mg ha−1 at 900 m to zero above 4000 m, and, inverse to tree biomass, herbaceous biomass was lower at mid-elevations (1 Mg ha−1) than in savannas (900 m, 3 Mg ha−1) or alpine vegetation (above 4000 m, 6 Mg ha−1). While the various land-use types dramatically decreased woody biomass at all elevations, though to various degrees, herbaceous biomass was typically increased. Our study highlights tropical montane forest biomass as important aboveground carbon stock and quantifies the extent of the strong aboveground biomass reductions by the major land-use types, common to East Africa. Further, it shows that elevation and land use differently affect different vegetation strata, and thus the matrix for other organisms.
