Degradação fisica das áreas de entorno do reservatório da usina hidrelétrica Luiz Gonzaga/PE BRASIL

Avaliaram-se as relações entre as propriedades físicas dos solos com erosão laminar e desbarracamento marginal em área próximas a Usina Hidrelétrica Luiz Gonzaga. Foram elencadas oito áreas A2, A3, A4, A11, A12, A13, A14 e A16, sendo o solo classificado como Neossolo Quartzarênico (RQ). Os solos das áreas experimentais e dos desbarrancamentos caracterizam-se por apresentar altos teores de areia, baixas quantidades de argila e silte. A intensidade de erosão laminar nas áreas experimentais foi classificada como nula a pequena e nos desbarrancamento marginais a erosão foi classificada como nula e pequena (A2, A4, A12, A13, A16) e média (A3, A11). O coeficiente de correlação entre argila e areia fina (r=0,50, p<0,05) foi significativo (Tabela 7). Em geral, foi constatado baixo grau de correlação linear entre a matéria orgânica e argila (r=0,45, p<0,05), matéria orgânica e areia fina (r=0,39, p<0,05) e argila e silte (r=0,30, p<0,05). Dessarte, os atributos físicos das unidades ambientais imprimem fragilidade, sobretudo no que tange a suscetibilidade à erosão e que aportam para o assoreamento do reservatório a longo prazo. Técnicas de bioengenharia são necessárias para atalhar o comprometimento da vida útil do reservatório

A list of land plants of Parque Nacional do Caparaó, Brazil, highlights the presence of sampling gaps within this protected area

Brazilian protected areas are essential for plant conservation in the Atlantic Forest domain, one of the 36 global biodiversity hotspots. A major challenge for improving conservation actions is to know the plant richness, protected by these areas. Online databases offer an accessible way to build plant species lists and to provide relevant information about biodiversity. A list of land plants of “Parque Nacional do Caparaó” (PNC) was previously built using online databases and published on the website "Catálogo de Plantas das Unidades de Conservação do Brasil." Here, we provide and discuss additional information about plant species richness, endemism and conservation in the PNC that could not be included in the List. We documented 1,791 species of land plants as occurring in PNC, of which 63 are cited as threatened (CR, EN or VU) by the Brazilian National Red List, seven as data deficient (DD) and five as priorities for conservation. Fifity-one species were possible new ocurrences for ES and MG states

We evaluated the relationships between physical properties of soil erosion laminar and marginal, close to the reservoir Luiz Gonzaga Hydroelectric Plant. Were listed eight areas A2, A3, A4, A11, A12, A13, A14 and A16, and the soil classified as quartzarenic neosol (RQ). The soils of the experimental areas and landslides are characterized by presenting high sand content, low amounts of clay and silt. The intensity of laminate erosion in the experimental areas was classified as zero in the small and marginal erosion landslides were classified as null and small (A2, A4, A12, A13, A16) and medium (A3, A11). The correlation coefficient between clay and fine sand (r = 0.50, p <0.05) was significant (Table 7). In general, we found a low degree of linear correlation between organic matter and clay (r = 0.45, p <0.05), organic matter and fine sand (r = 0.39, p <0.05) and clay and silt (r = 0.30, p <0.05). Thus faces the physical attributes of the units environmental fragility print, especially regarding the susceptibility to erosion and that contribute to the siltation of the reservoir in the long term.Avaliaram-se as relações entre as propriedades físicas dos solos com erosão laminar e desbarracamento marginal em área próximas a Usina Hidrelétrica Luiz Gonzaga.

Effectiveness of chlorthalidone plus amiloride for the prevention of hypertension the PREVER-Prevention Randomized Clinical Trial

Background-—Prehypertension is associated with higher cardiovascular risk, target organ damage, and incidence of hypertension. The Prevention of Hypertension in Patients with PreHypertension (PREVER-Prevention) trial aimed to evaluate the efficacy and safety of a low-dose diuretic for the prevention of hypertension and end-organ damage. Methods and Results-—This randomized, parallel, double-blind, placebo-controlled trialwas conducted in 21 Brazilian academicmedical centers. Participants with prehypertensionwho were aged 30 to70 years andwho did not reach optimal blood pressure after 3 months of lifestyle intervention were randomized to a chlorthalidone/amiloride combination pill or placebo and were evaluated every 3 months during 18 months of treatment. The primary outcome was incidence of hypertension. Development or worsening of microalbuminuria, new-onset diabetes mellitus, and reduction of left ventricular mass were secondary outcomes. Participant characteristics were evenly distributed by trial arms The incidence of hypertension was significantly lower in 372 study participants allocated to diuretics compared with358 allocated to placebo (hazard ratio 0.56, 95%CI 0.38–0.82), resulting in a cumulative incidence of11.7% in the diuretic arm versus 19.5% in the placebo arm(P=0.004). Adverse events; levels of blood glucose, glycosylated hemoglobin, creatinine, and microalbuminuria; and incidence of diabetes mellitus were no different between the 2 arms. Left ventricular mass assessed through Sokolow-Lyon voltage and voltage-duration product decreased to a greater extent in participants allocated to diuretic therapy compared with placebo (P=0.02). Conclusions-—A combination of low-dose chlorthalidone and amiloride effectively reduces the risk of incident hypertension and beneficially affects left ventricular mass in patients with prehypertension
