We apply stochastic seismic inversion and Bayesian facies classification for porosity modeling and igneous rock identification in the presalt interval of the Santos Basin. This integration of seismic and well-derived information enhances reservoir characterization. Stochastic inversion and Bayesian classification are powerful tools because they permit addressing the uncertainties in the model. We used the ES-MDA algorithm to achieve the realizations equivalent to the percentiles P10, P50, and P90 of acoustic impedance, a novel method for acoustic inversion in presalt. The facies were divided into five: reservoir 1,reservoir 2, tight carbonates, clayey rocks, and igneous rocks. To deal with the overlaps in acoustic impedance values of facies, we included geological information using a priori probability, indicating that structural highs are reservoir-dominated. To illustrate our approach, we conducted porosity modeling using facies-related rock-physics models for rock-physics inversion in an area with a well drilled in a coquina bank and evaluated the thickness and extension of an igneous intrusion near the carbonate-salt interface. The modeled porosity and the classified seismic facies are in good agreement with the ones observed in the wells. Notably, the coquinas bank presents an improvement in the porosity towards the top. The a priori probability model was crucial for limiting the clayey rocks to the structural lows. In Well B, the hit rate of the igneous rock in the three scenarios is higher than 60%, showing an excellent thickness-prediction capability.

Water mites (Hydrachnidia) are common external parasites of the medically important mosquitoes (Culicidae). Between April 2014 and April 2015, 64 mites from three genus, Arrenurus 71.9%, Limnochares 3.1%, and Hydrachna 25.0%, were collected from female mosquitoes in two rural locations near Cuiabá, Mato Grosso, Brazil. Dipterous species parasitized by water mites belonging to seven species: Anopheles (Nys.) darling, An. evansae, Aedes (Och.) scapularis, Ae. serratus, Mansonia (Man.) wilsoni, Psorophora (jan.) ferox, Ps. varipes. The most common specimens to accommodate the water mites were Anopheles (Nys.) darlingi and Psorophora (jan.) varipes. The prevalence of parasitism of mosquitoes by water mites found in this study was less than 5. However, few studies have addressed the ecological role of mites and their biotopes, as well as host-parasite interactions in Brazil.

S?o Paulo State is the main sugar cane producer and these agricultural activities are carried out in predominantly sandy soils, which require large amounts of phosphate fertilizers and amendments. This work evaluated the fertilizer-effect on the Al, Ba, fe, Mn and Ni released in a watershed with influence of sugar cane crops in the S?o Paulo State, Brazil, namely the Monjolo Grande Stream basin. five surface water sampling campaigns were carried out at the mouth of Monjolo Grande Stream in february, April, june, September and November 2010, characterizing the following parameters: discharge, pH, temperature, electric conductivity, dissolved oxygen and total and dissolved concentrations of Al, Ba, fe, Mn and Ni. Approximately 99% of Al and fe are transported annually in association with suspended sediments carried to the Monjolo Grande Stream by sheet erosion. The results also demonstrated that the increasing Al, Ba, fe and Mn concentrations dissolved in the waters of the Monjolo Grande Stream basin in the wet season are associated to phosphate fertilizers and amendments that are used extensively in agrichemical activities. However, with the current application rates, there has been no increase in the dissolved concentrations of these metals at levels that could pose risks to human health.

Background: Early life stress is a significant public health problem associated with increased rates of psychiatric disorders, especially those related to drug abuse. Objective: To identify the prevalence of early life stress in drug users, to compare the intensity of trauma in alcohol and crack users, and to relate the power of injury to the severity of drug dependence. Method: Cross-sectional analytical study with a sample of 105 alcohol and crack users treated by an outpatient service. The instruments for data collection were sociodemographic data questionnaire, the Mini-International Neuropsychiatric Interview, and the Severity of Dependence Scale. The categorical variables association was analyzed using the Chi-squared test, considering p Results: High prevalence of early stress and severity of dependence were identified, with higher rates among crack users. The early stress revealed in the Alcohol group high rates of emotional (88.7%) and physical (94.3%) neglect and in the Crack group significant frequency of physical (61.5%) emotional abuse (51.9%), sexual (46.2%), and emotional (78.8%) and physical (90.4%) neglect. Crack users are 2.6 times more likely to have been emotionally abused, and 2.1 times more likely to have been sexually abused during childhood when compared to the alcohol group. Conclusion: Early stress was prevalent with significant intensity in drug users, and evaluation of this problem is essential for a better understanding of these disorders.

Water availability is a fundamental condition for sustainable agriculture. However, a satisfactory water condition is not always possible in terms of quantity and quality in certain regions, such as the Brazilian semi-arid region. Thus, the purpose of this extremely important research was to evaluate the growth of cv. All Big with six combinations of wastewater plus saline (WW + SW) and two nutrient solution percentages, in a low-cost hydroponic system. The experiment was carried out in a greenhouse at the Department of Agricultural Engineering at federal University of Campina Grande. A completely randomized experimental design was used, with treatments arranged in a factorial scheme (6 × 2), with 5 replications, being the treatments composed by the combination of six proportions of wastewater with saline water (50%/50%;60%/40%;70%/30%;80%/20%;90%/10%;100% of wastewater) and two nutrient solution concentration (80% and 100%), totalizing 60 experimental units. The biometric variables were analyzed at 55 and 96 days after sowing, namely: plant height (PH), stem diameter (SD), leaf number (LN) and leaf area (LA). The interaction between the concentration of the nutrient solution and the ratio of the saline water with wastewater was influenced in the behavior of peppers (cv. All Big) biometric variables. The nutrient solution prepared at 80% of its normal concentration had better performance in the development of plants when mixed with the proportions of water containing more wastewater. The proportion 30% saline water and 70% wastewater (30/70) with concentration of 80% of the nutrient solution obtained better satisfactory results in the studied biometric variables.

AIM：To investigate the cytotoxic effects of spray-dried extracts of Phyllanthus niruri in combination with cis- platin on two cancer cell lines. METHODS： Colorectal carcinoma （HT29） and human hepatocellular carcinoma （HepG2） cells were treated with spray-dried extracts of Phyllanthus niruri （SDEPN） either alone or in combination with cisplatin at differ- ent concentrations （0.5 mg/mL and 1 mg/mL） for 4 h and 24 h. To verify and quantify cancer cells treated with these products as well as identify the cell cycle stage and cell viability, we stained the cells with prop- idium iodide and assessed them by flow cytometry. The percentage of cells in different cell cycle phases was quantified and data were expressed as histo- grams. Significant differences between groups were determined using analysis of variance and Bonferroni＇s test, as indicated. A value of P 〈 0.05 was considered to be statistically significant. RESULTS： SDEPN had significantly different cyto- toxic effects on HT29 （2.81 4- 0.11 vs 3.51 4- 1.13, P 〉 0.05） and HepG2 （5.07± 0.3 vs 15.9 ± 1.04, P 〈 0.001） cells when compared to control cells for 4 h. SDEPN also had significantly different cytotoxic effects on HT29 （1.91 ± 0.57 vs 4.53± 1.22, P 〉 0.05） and HepG2 （14.56 ± 1.6 vs 35.67 ± 3.94, P 〈 0.001） cells when compared to control cells for 24 h. Both cell lines were killed by cisplatin in a dose-dependent manner compared to control cells （HepG2 cells for 4 h： 10.78 ± 1.58 vs 53.89 ± 1.53, P 〈 0.001; 24 h： 8.9 ± 1.43 vs 62.78 ± 1.87, P 〈 0.001 and HT29 cells for 4 h： 9.52 ±0.913 vs 49.86 ± 2.89, P 〈 0.001; 24 h： 11.78 ± 1.05 vs 53.34 ± 2.65, P 〈 0.001）. In HT29 cells, pretreat- ment with SDEPN and subsequent treatment with cis-platin resulted in a greater number of cells being killed （12.78 ± 1.01 vs 93.76 ± 1.6, P 〈 0.001）. HepG2 cells showed significant cell killing with treatment with SDEPN when combined with cisplatin （12.87 ± 2.78 vs 78.8 ± 3.02, P 〈 0.001）. CONCLUSION： SDEPN is selectively toxic ag

Introduction: Polycystic ovarian syndrome (PCOS) is undoubtedly the commonest androgen disorder in woman’s fertile period and certainly one of the most prevalent causes of anovulation. The syndrome has an estimated prevalence of 4% - 10% among women of childbearing age. Previously, our group demonstrated the effect of gonadal white adipose tissue transplantation from wild-type lean and fertile female mice to isogenic obese anovulatory ob/ob mice. These complex metabolic interrelationships between obesity and PCOS have yet to be fully understood. The aim of this study was to evaluate the effect of gonadal white adipose tissue (WAT) transplantation from the wild-type lean and fertile female mice to isogenic obese, anovulatory mice (Lep ob/Lep ob) on the expression of glycolysis- and TCA cycle-related genes and obtain a general view of the glucose metabolism in the brain of these animals. Methods: fifteen ob/ob mice ranging from 2 to 3 months of age were divided into 3 experimental groups: control normal weight (n = 5), obese control (n = 5) and obese 7 days leptin treated (n = 5). The whole brains of the mice were processed for RNA extraction. The samples from each group were used to perform PCR assays using an array plate containing 84 primers to study the glucose metabolism-related genes. Results: The glycolysis- and TCA cycle-related genes were significantly downregulated. The most significantly affected genes were as follows: for glycolysis (fold regulation with p for the TCA cycle (fold regulation with p firm the ability of the adipose tissue-derived hormone leptin to regulate early crucial genes that are related to glycolysis mechanisms and to the TCA cycle. This hormone seems to revert early the central phys
