Aline de Freitas Brito,Caio Victor Coutinho de Oliveira,Lydiane Tavares Toscano,Alexandre Sérgio Silva
ISRN Hypertension , 2013, DOI: 10.5402/2013/581651
Abstract: Although the dietary approaches for stop hypertension (DASH) is well established and effective in reduction of blood pressure, in recent years, new scientific studies have indicated that specific food, nutrients isolated from foods, and even commercial food supplements are not covered by DASH. In this research, these nutrients were evaluated through a review using the databases of PubMed with the terms “dietary supplements and blood pressure” without a limit of date. Vitamins (C, D, and E) and minerals (potassium and copper) promote the greatest reductions in BP, around 7 to 14?mmHg for systolic blood pressure (SBP) and 4 to 5?mmHg for diastolic blood pressure (PAD). Antioxidants reduce SBP and DBP in 3 to 27?mmHg and 3 to 4?mmHg, respectively. Among the amino acids, only L-arginine was effective in promoting reduction of 20 and 15?mmHg for SBP and DBP, respectively. In food, the grape juice promoted the highest reductions in SBP and DBP, around 8?mmHg and 6?mmHg, respectively. Finally, for commercial supplements, the fermented milk product GAIOR, the grain salba, and fish oil promoted reductions of about 4,4; 6; and 5?mmHg and 3,4; 3; and 1?mmHg for SBP and DBP, respectively. Therefore, new nutrients, foods, and supplements can enrich the recommendations of the DASH. 1. Introduction The degenerative diseases are the most prevalent in the world today, representing one of the greatest public health problems in the actuality [1]. According to estimates of the World Health Organization [2], these diseases are responsible for about 60% of all deaths worldwide, and 46% of the global burden of diseases affecting the population. Among them predominate obesity (12% of world population) [2], diabetes (10% of world population) [3], and dyslipidemia (7.9% of deaths worldwide) [2]. The main cause of these comorbidities have been the stress, sedentary lifestyle and eating habits. All of these diseases are potentially able to promote increased blood pressure. While the fatty produced substances such as angiotensinogen and proinflammatory contribute to elevate blood pressure [4]; hyperlipidemia results in excessive oxidation of low density lipoproteins with subsequent atherosclerotic process [5]. The state of diabetes promotes strong oxidative stress that contributes unequivocally to endothelial dysfunction, inflammation, and vasoconstriction which increases blood pressure [6]. Therefore, these three states of morbidity are among the risk factors of hypertension that are, among all chronic diseases, the most prevalent, affecting about 30% of the world population [2],

Varia??o anat?mica da artéria torácica interna lateral: relato de caso
Rocha, Rogério Porto da;Oliveira, Helenice Souza de;Lopes, Aline Urias;Rios, Sérgio Luz;
Revista do Colégio Brasileiro de Cirurgi?es , 2007, DOI: 10.1590/S0100-69912007000500015
Abstract: the objective of this report was to describe a variation in the origin of the lateral internal thoracic artery (lita), a variable large-caliber artery in the thoracic wall. this report presents a case in which a trunk coming from the subclavian artery (sca) bifurcates and gives origin to the lita and internal thoracic artery (ita). this case demonstrates an unusual bilateral origin for the lita, which emerges together with the ita rather than directly from the sca, as could be expected. although such presentation is uncommon, the possibility that it could be damaged during surgical interventions such as thoracotomy and pleural drainage justifies our report .

Abstract: O gênero Eucalyptus possui destaque em plantios florestais comerciais em virtude de apresentar crescimento rápido e ser adaptado às condi es climáticas do Brasil. Dentre as fases de maior importancia para produ o de mudas de eucalipto via propaga o vegetativa, destaca-se a de enraizamento em raz o das exigências hídricas, nutricionais e de manejo, passíveis de comprometer a qualidade das mudas na crescente demanda silvicultural brasileira. Realizou-se esta pesquisa objetivando-se determinar a soma térmica para o enraizamento de estacas clonais de eucalipto (Eucalyptus grandis x E. urophylla) e gerar equa es de estimativa para o acúmulo de biomassa na mesma fase de produ o, com base no conceito de graus-dia (tempo térmico). O trabalho foi conduzido em casa de vegeta o climatizada no viveiro de pesquisas do Departamento de Engenharia Florestal, da Universidade Federal de Vi osa, Minas Gerais. No início do enraizamento a média da biomassa fresca das mudas foi de 0,76 ± 0,17 g e da biomassa seca de 0,17 ± 0,04 g. Ao final do enraizamento a média da biomassa fresca e seca das mudas foi de 1,49 ± 0,43 g e 0,21 ± 0,06 g, respectivamente. Para o enraizamento das estacas de eucalipto foram necessários 316,42 graus-dia acumulados. The genus Eucalyptus is important in commercial forest plantations due to its rapid growth and ability to adapt to Brazilian climatic conditions. Among the most important stages for production of eucalyptus seedlings, through vegetative propagation, rooting is highlighted due to its requirements for water, nutrients and management which may compromise the quality of seedlings growing demand in Brazilian silviculture. This study aimed to determine the thermal sum to the rooting of clonal cuttings of eucalyptus (Eucalyptus grandis x E. urophylla) and generate equations to estimate the biomass accumulation in the same stage of production, based on the concept of degree-days (thermal time). The study was conducted in an acclimatized greenhouse in the Seedling Nursery of the Department of Forestry, Universidade Federal de Vi osa, Minas Gerais State, Brazil. At the start of rooting, the mean fresh weight of seedlings was 0.76 ± 0.17 g and the dry biomass was 0.17 ± 0.04 g. At the end of rooting, the means of fresh and dry biomass of seedlings were 1.49 ± 0.43 g and 0.21 ± 0.06 g, respectively. For rooting of eucalyptus seedlings 316.42 degree-days were necessary.

Abstract: Root lesions may affect both dorsal and ventral roots. However, due to the possibility of generating further inflammation and neuropathic pain, surgical procedures do not prioritize the repair of the afferent component. The loss of such sensorial input directly disturbs the spinal circuits thus affecting the functionality of the injuried limb. The present study evaluated the motor and sensory improvement following dorsal root reimplantation with fibrin sealant (FS) plus bone marrow mononuclear cells (MC) after dorsal rhizotomy. MC were used to enhance the repair process. We also analyzed changes in the glial response and synaptic circuits within the spinal cord. Female Lewis rats (6–8 weeks old) were divided in three groups: rhizotomy (RZ group), rhizotomy repaired with FS (RZ+FS group) and rhizotomy repaired with FS and MC (RZ+FS+MC group). The behavioral tests electronic von-Frey and Walking track test were carried out. For immunohistochemistry we used markers to detect different synapse profiles as well as glial reaction. The behavioral results showed a significant decrease in sensory and motor function after lesion. The reimplantation decreased glial reaction and improved synaptic plasticity of afferent inputs. Cell therapy further enhanced the rewiring process. In addition, both reimplanted groups presented twice as much motor control compared to the non-treated group. In conclusion, the reimplantation with FS and MC is efficient and may be considered an approach to improve sensory-motor recovery following dorsal rhizotomy.

Abstract: Twenty-eight women, selected from a healthy population sample (n = 148) were classified according to three CETP levels, all statistically different: CETP deficiency (CETPd ≤ 4.5%, n = 8), high activity (CETPi ≥ 23.8, n = 6) and controls (CTL, CETP ≥ 4.6% and ≤ 23.7%, n = 14). After a 12 h fast they underwent an oral fat tolerance test (40 g of fat/m2 of body surface area) for 8 hours. TG, TG-rich-lipoproteins (TRL), cholesterol and TRL-TG measurements (AUC, AUIC, AR, RR and late peaks) and comparisons were performed on all time points. Lipases and phospholipids transfer protein (PLTP) were determined. Correlation between carotid atherosclerosis (c-IMT) and postprandial parameters was determined. CETP TaqIB and I405V and ApoE-ε3/ε2/ε4 polymorphisms were examined. To elucidate the regulation of increased lipemia in CETPd a multiple linear regression analysis was performed.In the CETPi and CTL groups, CETP activity was respectively 9 and 5.3 higher compared to the CETPd group. Concentrations of all HDL fractions and ApoA-I were higher in the CETPd group and clearance was delayed, as demonstrated by modified lipemia parameters (AUC, AUIC, RR, AR and late peaks and meal response patterns). LPL or HL deficiencies were not observed. No genetic determinants of CETP deficiency or of postprandial lipemia were found. Correlations with c-IMT in the CETPd group indicated postprandial pro-atherogenic associations. In CETPd the regression multivariate analysis (model A) showed that CETP was largely and negatively predicted by VLDL-C lipemia (R2 = 92%) and much less by TG, LDL-C, ApoAI, phospholipids and non-HDL-C. CETP (model B) influenced mainly the increment in ApoB-100 containing lipoproteins (R2 = 85% negatively) and phospholipids (R2 = 13%), at the 6thh point.The moderate CETP deficiency phenotype included a paradoxically high HDL-C and its sub fractions (as earlier described), positive associations with c-IMT, a postprandial VLDL-C increment predicting negatively CETP activi

Abstract: the main objective of this work is to evaluate the occurrence of bromophenols (2bromophenol, 4bromophenol, 2,4dibromophenol, 2,6dibromophenol and 2,4,6tribromophenol), in the flesh and guts in two species of the lutjanidaefamily: lutjanus synagris and ocyurus chrysurus. the bromophenols were extracted by steam distillation with pentaneether (7:3 v/v), identified by reverse phase high performance liquid chromatography (hplcuv), and quantified bythe externalstandard method. total bromophenol concentrations were similar in the muscle of both species, rangingfrom 36 ng g1 to 349 ng g1. the total bromophenol concentrations in stomach (ranging from 12 ng g1 to 586 ng g1)were slightly higher than in muscle. the presence of bromophenol in the muscles of the species under study may occuras a result of their diet. the results of this work are therefore expected to contribute toward a better understanding ofthe path of bromophenol absorption from the fish's stomach to the rest of its body.
