Spondias sp. (Anacardiaceae), popularly known as cajá-umbu, is an endemic plant from Northeastern Brazil, where their leaves are widely used in folk medicine to treat inflammatory processes, while their fruits have a great agro industrial potential. This study was designed to evaluate hepatoprotective, antinociceptive, antioxidant, antimicrobial and anti-inflammatory properties, as well as the acute toxicity and repeated dose 28, using a methanolic extract (MES), a fraction rich in flavonoids (FRF) and a precipitate from Spondias sp.leaves. The antioxidant activity of them was valued to evaluate their free radical scavenger capacity by DPPH test, whereas MES and FRF were used to evaluate while the preventive action on carbon tetrachloride (CCl4)-induced hepatotoxicity. Seven groups (n=5) of female Wistar rats were used as follows: control group, CCl4-intoxicated group treated with EMS (500 mg/kg) for 7 days, three CCl4-intoxicated groups treated with FRF (25, 50 and 75 mg/kg) for 7 days and the CCl4-intoxicated group treated with Legalon ® (silimarina; (phytotherapeutic reference) (50 mg/kg; 7 days). MES and FRF showed a protective action against liver injury induced by CCl4, being observed a significant reduction of serum enzyme activity marker of liver damage (alanine transaminase and aspartate transaminase). On the other hand, the lipid peroxidation (SRAT) decrease, as well as the increase of glutathione content and enzyme activity of antioxidant defense system (SOD, CAT, GPx) toward near normal values indicated the ability of EMS to restore the oxidative imbalance induced by CCl4. The histological analysis confirmed the hepatoprotection, compared to degenerative changes in CCl4-treated group. This hepatoprotetor effect was similar to that shown by Legalon®. The in vitro high antioxidant capacity of extract (93.16 ± 1.00%) showed analogous results to those obtained by Carduus marianus BHT (reference standard). This fact explains the obtained results in vivo. Although no antimicrobial activity was detected, EMS and FRF promoted the antinociceptive effect induced in the second phase by the intraplantar formalin test, evidencing the anti-inflammatory action; confirmed by the carrageenan-induced peritonitis model. The evaluation of the mechanical allodynia (CFA a 80%) demonstrated the involvement of the Spondias sp. chemical composition in the anti-inflammatory activity toward the acute processes. The acute exposure and repeated dose during 28 days did not produce significant changes in the parameters that evaluate toxicity. Together the experimental results reveal, that Spondias sp. leaf extracts have a promising potential in pharmaceutical area, and due to its non-toxic condition present efficiency and security

The aim of this study was to assess the impact of the Family Health Program (FHP) on a number of oral health indicators in the population of Natal, Brazil. The study is characterized as a quasi-random community intervention trial. The intervention is represented by the implementation of an Oral Health Team (OHT) in the FHP prior to the study. A total of 15 sectors covered by the FHP with OHT were randomly drawn and paired with another 15 sectors, based on socioeconomic criteria, not covered by the teams. A few sectors were lost over the course of the study, resulting in a final number of 22 sectors, 11 covered and 11 not covered. We divided the non-covered areas into two conditions, one in which we considered areas that had some type of assistance program such as the Community Agents Program (CAP), FHP without OHT, BHU (Basic Health Unit) or no assistance, and the other, in which we considered areas that had only BHU or no assistance. Community Health Agents (CHAs) and Dental Office Assistants (DOAs) applied a questionnaire-interview to the most qualified individual of the household and the data obtained per household were transformed into the individual data of 7186 persons. The results show no statistical difference between the oral health outcomes analyzed in the areas covered by OHT in the FHP and in non-covered areas that have some type of assistance program, with a number of indicators showing better conditions in the non-covered areas. When we considered the association between covered and non-covered areas under the second condition, we found a statistical difference in the coverage indicators. Better conditions were found in covered areas for indicators such as I have not been to the dentist in the last year with p < 0.001 and OR of 1.64 and I had no access to dental care with p < 0.001 and OR of 2.22. However, the results show no impact of FHP with OHT on preventive action indicators under both non-covered conditions. This can be clearly seen when we analyze the toothache variable, which showed no significant difference between covered and non-covered areas. This variable is one of the most sensitive when assessing oral health programs, with p of 0.430 under condition 1 and p of 0.038 under condition 2, with CI = 0.70-0.90. In the analysis of health indicators in children where the proportion of deaths in children under age 1, the rate of hospitalization for ARI (Acute Respiratory Infections) in those under age 5 and the proportion of individuals born underweight were considered, a better condition was found in all the outcomes for areas with FHP. Therefore, we can conclude that oral health in the FHP has little effect on oral health indicators, even though the strategy improves the general health conditions of the population, as, for example child health

A deficiência de estrógenos, as alterações do perfil lipídico, o ganho de peso e o sedentarismo são considerados os principais fatores para a maior prevalência de hipertensão arterial em mulheres na menopausa. Na tentativa de reduzir a incidência da hipertensão arterial nessa população, diversas abordagens têm sido empregadas, porém a maioria dos trabalhos mostra que, nesse momento, a mudança de estilo de vida parece ser a melhor estratégia para o controle da hipertensão arterial e de seus fatores de risco nessa fase de vida da mulher - entre elas a prática de atividade física regular. O exercício físico contínuo, no qual a intensidade é mantida constante (leve/moderada), tem sido empregado na maioria dos trabalhos dentro da área de Saúde, com evidentes efeitos benéficos sobre as doenças cardiovasculares e endócrino-metabólicas. A prescrição do exercício contínuo caracteriza-se por atividades de pelo menos 30 minutos, três dias por semana, numa intensidade de 50 a 70% da frequência cardíaca máxima. O exercício físico intermitente caracteriza-se por alterações em sua intensidade durante a realização do treinamento, podendo variar de 50 a 85% da frequência cardíaca máxima, durante dez minutos. Atualmente, o exercício físico intermitente tem sido também empregado como forma de treinamento físico em diversas clínicas de controle de peso e em treinamentos personalizados, o que é devido ao menor tempo de execução do exercício físico intermitente. Além disso, trabalhos mostram que as adaptações metabólicas e o condicionamento físico são similares aos observados no exercício contínuo, que exigem maior tempo de execução para obter as mesmas adaptações celulares. Assim, essa revisão abordou a importância do exercício físico no controle da pressão arterial bem como os principais estudos conduzidos em modelos experimentais de menopausa e em mulheres, relacionando a hipertensão arterial e os mecanismos envolvidos em sua gênese e as perspectivas futuras.

Foram analisadas 7.657 amostras de sangue provenientes de 48 cidades das regiões de São José do Rio Preto e de Presidente Prudente, com o objetivo de detectar e conscientizar os portadores de hemoglobinas anormais. As análises efetuadas mostraram que 3,47% tinham hemoglobinas anormais, sendo 2,26% portadores de variantes moleculares (Hbs, AS, AC, SS, SC, AJ, AB2) e 1,21% de talasse-mias (alfa e beta). Os resultados obtidos evidenciaram que estudos semelhantes, além de propiciar o melhor conhecimento das causas genéticas, bioquímicas e hematológicas dessas alterações hereditárias, oferecem também a oportunidade de estimar a importância que essas patologias representam para a saúde pública do nosso país. A ação preventiva foi estabelecida por meio de reuniões de esclarecimentos médicos e biológicos aos portadores de hemoglobinas anormais.

Fungicide application is one of the control strategies of fungal diseases in corn leaves. In Brazil, there are no fungicides recorded for the control of corn macrospora leaf spot (MLS). The aim of this study was to assess the efficacy of 16 fungicides on MLS control in a protective, curative and eradicant form. Fungicides of the chemical groups of benzimidazoles, strobilurins and triazoles were used alone or in mixture, in completely randomized block design, with six replicates of five plants, totaling 30 plants per treatment. The experiments were carried out in a greenhouse with the single-cross hybrid AS 1565 in phenological stage of two to six expanded leaves, using an isolate of S. macrospsora from the same hybrid. The inoculum was deposited into the cartridge of plants at 48 hours after, 48 hours before and 10 days before fungicide applications for preventive, curative and eradicant action, respectively. The experiment was repeated twice. The data underwent analysis of variance (p<0.05), and the means of treatments were compared by using the Scott-Knott test (p<0.05). Severity was estimated at 21 days after inoculations. All fungicides significantly differed from the control treatment in the preventive, curative and eradicant action. For the preventive action, mean disease control was 85%. The mixture of triazoles plus strobilurins controlled, on average, 75% of the disease severity, while the isolated products such as strobilurins reduced it by 62%, benzimidazoles by 55% and triazoles by 38% for the curative action. The lowest control was obtained for the eradicant action, with mean reduction of 40.1% in the disease severity and no significant difference among fungicides.

O presente estudo sobre o trabalho escravo está pautado na análise dos princípios gerais e constitucionais que norteiam a matéria, em especial, o princípio da dignidade humana, discutindo principalmente as hipóteses caracterizadoras do crime de redução do trabalhador à condição análoga à de escravo, os bens jurídicos tutelados, e as possíveis formas de combater essa prática. A partir desse referencial, aprofundamos a pesquisa nas formas de atuação preventiva do Estado, como meio de propiciar a inclusão social dos trabalhadores. Ao abordar a problemática do trabalho escravo, buscamos discutir mecanismos de inclusão social, por meio de ações capazes de inibir a prática do trabalho escravo no momento do aliciamento da mão-de-obra. Esta pesquisa tem por finalidade principal chamar a atenção para o problema que vivenciamos ainda hoje no meio rural brasileiro, demonstrando a necessidade de se agir efetivamente contra esta prática secular que é submeter o ser humano a condições subumanas de vida, por meio da superexploração do trabalho, com vistas a coibir este crime desde o momento do aliciamento, e não apenas por meio de ações repressivas como o resgate. Em outras palavras, defendemos a necessidade de atuação no momento a priori da escravidão – na arregimentação. O estudo está dividido em três capítulos, o primeiro destina-se à compreensão teórico-jurídica do trabalho escravo, analisando o crime sob as óticas internacional, constitucional e penalista; o segundo trata da análise das formas de atuação repressiva do Estado, trazendo entendimentos jurisprudenciais trabalhistas e penais a respeito do tema, cujas decisões judiciais foram selecionadas principalmente no Estado do Pará; e o terceiro capítulo traz o estudo de métodos de atuação preventiva, como forma de combate ao trabalho escravo e de promoção da inclusão social, percorrendo detalhadamente as características do aliciamento ilegal de trabalhadores, propondo, ao final, a regularização prévia da relação de trabalho, transformando o aliciamento ilegal em contrato de trabalho regular.

Bisphenol A (BPA) is one hormonally active chemical with potential deleterious effects on reproductive organs, including breast and prostate. In contrast, genistein (GEN) is the major phytoestrogen of soy that presents potential protective effects against hormone-dependent cancers, including that of the prostate. Thus, pregnant Sprague-Dawley rats were treated with BPA at 25 or 250 μg/kg/day by gavage from gestational day (GD) 10-21 with or without dietary GEN at 250 mg/kg/chow (∼5.5 mg/kg/day). Then, male offspring from different litters were euthanized on post-natal day (PND) 21 and 180. At PND21, BPA 25 exposure induced early prostatic changes while dietary GEN attenuated some deleterious actions this xenoestrogen on epithelial cell proliferation levels, androgen receptor expression and prostatic architecture in male offspring. At PND180, a significant increase in incidence of prostatic multifocal inflammation/reactive hyperplasia and atypical hyperplasia were observed in male offspring from dams that received BPA 25. On the other hand, maternal GEN feeding attenuated some the adverse effects of BPA 25 on prostate disease at late-in-life. This way, the present findings point to preventive action of dietary GEN on deleterious effects of gestational BPA exposure in both early and late prostate development in offspring F1.
