Abstract: in this paper, we ask ourselves who should, can and has the will to promote health in the rural zone today. the fields of science and public policy were chosen as our primary focus of dialogue conducted from the perspective of the right to health and a healthy environment. seven lessons emerged: (1) in addition to the surveillance of isolated chemical risks, the relation between agrochemicals and health should be investigated in the context of conservative agricultural modernization; (2) it is mandatory and urgent to discover the health problems related to the use of agrochemicals; (3) the state has been successful in its support of agribusiness, but highly inefficient at enforcing policies to safeguard social rights; (4) sectors of society linked to rural organizations have played an important role in the public policies combating agrochemicals and protecting health; (5) studies must help deconstruct the myths surrounding the green revolution model; (6) we are faced with the challenge of contributing to the construction of an emerging scientific paradigm founded on an ethical-political commitment to the most vulnerable social elements; (7) rural communities are creating agro-ecological alternatives for life in semiarid areas.

PLOS ONE , 2014, DOI: 10.1371/journal.pone.0088588
Abstract: Objective Congenital toxoplasmosis is a public health problem in Brazil. This study aimed to determine risk factors associated with congenital toxoplasmosis in Minas Gerais which is the second largest Brazilian State based on number of inhabitants, and its territorial extension is larger than that of France. Methods: Population-based case-control study to assess the association between congenital toxoplasmosis and maternal exposure to infection risk factors. The study included mothers/children participating in the Minas Gerais Newborn Screening Program. The cases consisted of 175 mothers of infected children, and the controls consisted of 278 mothers of children without suspected infection. The associations were assessed through binomial logistic regression with p≤0.05. Results The variables associated with lower probability of toxoplasmosis were: older mother age (OR = 0.89; CI95% = 0.85–0.93), higher level of education (OR = 0.85; CI95% = 0.78–0.92), access to potable water (OR = 0.21; CI95% = 0.08–0.51), and home with flush toilet (OR = 0.18; CI95% = 0.04–078). The variables associated with higher probability of infection were: cats in the neighborhood (OR = 2.27; CI95% = 1.27–4.06), owning or visiting homes with domestic cats (OR = 1.90; CI95% = 1.09–3.31), handling the soil (OR = 2.29; CI95% = 1.32–3.96), and eating fresh meat not previously frozen (OR = 3.97; CI95% = 2.17–7.25). After stratification according region of residence (rural or urban/peri-urban), home with flush toilet and consumption of treated water were protective against the disease only in the rural stratum. Conclusions In Minas Gerais, congenital toxoplasmosis has been associated with poor socioeconomic conditions. Considering maternal exposure to sources of Toxoplasma gondii, the predominating risk factors were those related to the ingestion of oocysts. It is expected that these results will contribute to development of a program for prevention of congenital toxoplasmosis adapted to the reality of the population of Minas Gerais. The differences between populations living in rural and urban areas regarding the main risk factors for toxoplasmosis point to the need of considering regional specificities in planning strategies to control congenital toxoplasmosis.

Abstract: The objectives were to evaluate alterations in ischemic rat pups, from dams administered with curcumin (25 and 50?mg/kg). Ten-day-old male pups were subjected or not (SO) to brain ischemia and reperfusion, for 1, 7, and 14 days (this last group was submitted to behavioral evaluation). After that, pups were euthanized for determinations of striatal DA and DOPAC in SO, ischemic from untreated (ICUD) or curcumin treated (ICTD) dams, as well as hippocampal immunohistochemistry assays for iNOS and COX-2 and cresyl violet staining. At the 14th postischemia day, the ICUD group showed increased locomotor activity and rearing behavior, which were reversed in ICTD animals. ICUD pups presented decreased striatal DA and DOPAC levels, relatively to SO, mainly at the 1st postischemia day, but also at the 7th and 14th days which were partially reversed in ICTD pups. A greater number of viable neurons were observed in ICTD, as related to the ICUD group. Ischemia increased iNOS and COX-2 expressions, in CA1 and CA3 areas, at the 1st, 7th, and 14th postischemia days, and these effects were minimized in ICTD pups. In conclusion, the prenatal curcumin treatment was shown to be neuroprotective where the drug anti-inflammatory and antioxidant effects probably play a role. 1. Introduction Cerebral ischemia is a very common cerebrovascular disease and one leading cause of morbidity and mortality worldwide, whose complex pathology includes inflammatory events, as aggregation of inflammatory cells and upregulation of cytokines [1]. Furthermore, hypoxic-ischemic brain damage is a major cause of acute mortality and chronic neurologic morbidity, in infants and children. Much of our understanding on mechanisms of hypoxic-ischemic brain damage and potential therapeutic interventions derive from experimental models in the adult animal. It is accepted that a cerebral hypoxic-ischemic event of sufficient severity to deplete tissue energy reserves is rapidly followed by acidosis, glutamate excitotoxicity, generation of reactive oxygen species, and oxidative stress, followed by prolonged periods of delayed cell death and inflammation [2]. However, direct application of adult brain findings to the newborn animal is not a simple task, since the immature brain is generally considered resistant to the damaging effects of hypoxia and ischemia. At the same time, the immature brain exhibits periods of heightened sensitivity to injury, dependent upon the brain specific developmental stage [2]. Cerebral ischemia causes disturbances in a variety of cellular and molecular mechanisms, including

Os limites ficaram por conta dos condicionantes institucionais, que para serem superados, requer que os gestores públicos assumam, de fato, uma política educacional voltada para as camadas populares na rede pública municipal de educa o de Maceió
Regularity for degenerate two-phase free boundary problems
Raimundo Leit?o,Olivaine S. de Queiroz,Eduardo V. Teixeira
Mathematics , 2012,
Abstract: We provide a rather complete description of the sharp regularity theory for a family of heterogeneous, two-phase variational free boundary problems, $\mathcal{J}_\gamma \to $ min, ruled by nonlinear, $p$-degenerate elliptic operators. Included in such family are heterogeneous cavitation problems of Prandtl-Batchelor type; singular degenerate elliptic equations; and obstacle type systems. The Euler-Lagrange equation associated to $\mathcal{J}_\gamma$ becomes singular along the free interface $\{u= 0\}$. The degree of singularity is, in turn, dimed by the parameter $\gamma \in [0,1]$. For $0< \gamma < 1$ we show local minima is locally of class $C^{1,\alpha}$ for a sharp $\alpha$ that depends on dimension, $p$ and $\gamma$. For $\gamma = 0$ we obtain a quantitative, asymptotically optimal result, which assures that local minima are Log-Lipschitz continuous. The results proven in this article are new even in the classical context of linear, nondegenerate equations.
