Abstract: Background Lutzomyia longipalpis (Diptera: Psychodidae) is the major vector of Leishmania (Leishmania) infantum and thus plays a crucial role in the epidemiology of American visceral leishmaniasis (AVL). This vector is the best studied species of sand fly in the Neotropical region. Many studies claim that this vector is in fact a species complex; however there is still no consensus regarding the number of species that belong into this complex or the geographical distribution of sibling species. The aim of the present study was to analyze the genetic relationships within?Lu. longipalpis?populations in the state of Mato Grosso do Sul (MS), Brazil. Methodology/Principal Findings We collected 30 Lu. longipalpis (15 females and 15 males) from five localities (Campo Grande, Três Lagoas, Aquidauana, Miranda and Bonito) and 30 Lu. Cruzi from Corumbá, totaling 180 sandflies from MS, and 30 Lu. longipalpis from Estrela de Alagoas, state of Alagoas (AL), Northeast Brazil. We show that eight previously described microsatellite loci were sufficient in distinguishing Lu. longipalpis from Lu. Cruzi, which is a closely related species, and in differentiating between Lu. longipalpis collected in MS versus Estrela de Alagoas. Analyses of the genotypes revealed introgression between sympatric Lu. longipalpis and Lu. Cruzi. Conclusions/Significance Our findings support the hypothesis of cryptic species within the Lu. longipalpis complex. Furthermore, our data revealed introgression between Lu. longipalpis and Lu. cruzi. This phenomenon should be further investigated to determine the level and incidence of hybridization between these two species. We also demonstrated that microsatellite markers are a powerful tool for differentiating sand fly populations and species. The present study has elucidated the population structure of Lu. longipalpis in MS and, by extension, the Neotropical Lu. longipalpis complex itself.

Abstract: alternative methods were investigated for the reduction of astringency (detannization) and conservation of jambolan fruit (syzygium cumini, l.). in the first experiment, fruits were harvested at an intermediate ripening stage, maintained at room temperature and subjected to the following treatments: control (normal atmosphere), 98kpa co2, 20kpa co2, 98kpa n2, ethylene (100ppm), 1-mcp (1ppm) followed by treatment with ethylene (100ppm) and 3,85ml absolute ethanol l-1. acetaldehyde, soluble tannin, fruit firmness and astringency were evaluated. in the second experiment, fruits were harvested ripe and stored under passive modified atmosphere at room temperature (pmart, 23±1°c) and passive modified atmosphere under cold storage (pmacs, 4±1°c) for 5, 10 and 15 days. fruits treated with n2, ethylene and ethanol showed the best detannization results, with increased acetaldehyde content, reduction of soluble tannins and astringency. however ethylene and ethanol treatments induced excessive softening of the fruit. storage under pmar kept the purple-blue color of fruits and, besides preventing fungal incidence, it aided the maintenance of the total phenolic content, ascorbic acid and antioxidant activity of fruits.

Abstract: objective: to review the current literature about parent′s ability to perceive the body weight of their children, the beliefs related to weight, the factors that influence their perception, as well as the possible actions to enhance the awareness of parents about their children's excess of weight and it's consequences. data sources: the databases used in the research were: medline, scielo and scopus. studies from 2000-2010 addressing the parental perception of children's body weight were included. data synthesis: the parents perception of their children's body weight was generally poor, despite the diversity of the samples studied across different regions, socio-economic status and educational levels. many parents of overweight children do not recognize or do not consider overweight/obesity of their children as a health problem. the wrong perceptions were frequently associated with factors like children's age (harder to perceive the excess of weight in younger children), gender (girl's excess of weight is more frequently noticed), poor education and misunderstanding of the growth curves. conclusions: the lack of perception and awareness of parents about the nutritional status of children is one of the factors that act against the success of the prevention and the treatment of obesity.

Scientia Agricola , 2009, DOI: 10.1590/S0103-90162009000100008
Abstract: barium salts are used extensively for industrial purposes, generating residues that, if not appropriately disposed, can increase soil ba content. the aim of the present work was to evaluate ba extraction potential of mustard (brassica juncea czern.), sunflower (helianthus annuus l.), and castor bean (ricinus communis l.), grown in a soil artificially contaminated with increasing ba additions. a greenhouse experiment was carried out by adding baso4 to a rhodic hapludox sample, at the 0, 150 and 300 mg kg-1 rates. after harvesting, the pot soil material was also analyzed for exchangeable ba by cacl2 extraction and by an ion exchange resin method. none of the plant species tested presented toxicity symptoms, decreased nutrient accumulation or decreased dry matter production in response to ba treatments. the accumulation of ba, in decreasing capacity was: sunflower> mustard> castor bean. the largest accumulation was with sunflower at 300 mg kg-1 of ba added to the soil. when evaluated by the transference factor, none of the species tested was an efficient ba accumulator, up to 47 days after emergence. the ion exchange resin method was not adequate to evaluate ba availability to these plants.

Abstract: An 1-year-old male Basset Hound dog was evaluated for chronic intermittent vomiting, hematemesis, and melena which had been ongoing for several months. The histopathologic examination revealed that all layers of the small intestine were thicker than normal. The lamina propria of the mucosa, including the villi, exhibited a prominent cellular infiltrate which consisted of numerous eosinophils and an increased numbers of plasma cells in addition to the normal lymphocytic component. The muscularis mucosa was invaded, and in some places disrupted, by eosinophils, which also infiltrated into the submucosa and muscularis propria. This report describes the pathological findings of a case of eosinophilic gastroenteritis (EG) in a dog.
ADRB2, ADRB3, BDKRB2 and MTNR1B Genes Related to Body fat Modulation and Its Interaction with Physical Activity and Blood Pressure  [PDF]

Abstract: Hypertension (HTN) is the risk factor that most contributes to mortality rates in the world, followed by physical inactivity and obesity. Despite the influence of genetic factors on the genesis of HTN, blood pressure levels are strongly influenced by environmental factors such as physical inactivity and overweight, characterizing it as a polygenic disease. Genetic components and environmental factors such as physical exercise may modulate the phenotype of individuals predisposed to medical conditions such as HTN, independently of modifiable factors such as increased levels of adiposity; however, studies have shown that polymorphic forms detected in genes involved in the mechanisms of blood pressure regulation and also related to body fat modulation may interact with physical activity levels and HTN. The aim of this article is to review the interactions between polymorphisms in ADRB2, ADRB3, BDKRB2 and MTNR1B genes, physical activity and blood pressure.

Applied and Environmental Soil Science , 2011, DOI: 10.1155/2011/239607
Abstract: The liquid sewage sludge (LSS) was applied on a field experiment during four years at successive applications to evaluate the changes in soil attributes and on Surinam grass (Brachiaria decumbens) uptake of nutrients. A randomized blocks experimental design, with two treatments (with and without LSS) and three repetitions, was used. Land application of LSS did not alter soil organic matter and exchangeable K until 40?cm depth. However, it increased soil pH, base saturation, labile P, and available Zn and did not change the concentrations of available B (hot water) and Cu, Fe, and Mn (DTPA) at 0–20?cm and 20–40?cm depths and LSS was a source of N, K, P, Ca, Mg, and Zn for the grass, but decreased leaf Mn concentration. 1. Introduction In the initial steps of water pollution control process there is a great concern about the liquid phase treatment of sewage originated from districts and cities, in order to protect water resources and public health [1]. The treatment of this wastewater generates a solid residue known as biosolid or sewage sludge (SS), which consists mainly of a mass of fungi, bacteria, and protozoa that are responsible for the sewage organic matter degradation. Due to its intrinsic high organic matter content, followed by a variable concentration of other nutrients, heavy metals, human pathogens, and some organic chemicals that may or not be partially degraded during the process, there is a general concern on its environmentally sound disposal. Among the available destination options, the most used still are the SS disposal in sanitary landfills, ponds, or lagoons, and the application to agricultural lands. As in fact 76% of Brazilian cities do not have adequate sanitary landfills for solid residues disposal, which are usually discarded at open field, the disposal in agricultural lands appears to be an economical and environmentally viable way for this purpose. Nevertheless, the SS use in agriculture may be restricted by the presence of heavy metals, pathogens, and persistent organic compounds, depending on the SS original composition [2, 3]. In general, SS treated soil presents improved soil physical attributes, such as greater aggregate stability [4, 5] and lower soil density, providing better root and shoots development with significant plant biomass increase [6]. Furthermore, the presence of plant macro and micronutrients in SS, mainly N, P, S Ca, Mg, and Zn, may supply, total or in part, the plant’s demand for these elements [7]. Approximately one third of N [8] and up to 64% of P [9] content in SS would be available to plants in the

Abstract: Mesenchymal stem cells (MSCs) were originally described by Friedenstein and colleagues [1,2] in the nonhematopoietic component of bone marrow where they participate in regulating hematopoietic stem cell maturation and emigration into the circulation. Since that time, they have been isolated from the connective tissue of almost all organs, including adipose, periosteum, synovial fluid, muscle, hair follicles, root of deciduous teeth, articular cartilage, placenta, dermis, umbilical cord, Wharton's jelly, lung, liver and spleen [3-5]. It has been posited that MSCs in these organs, like other stem cells, function as a source of cells for replacement and regeneration during normal cellular turnover, repair of injured tissue, or in response to biological aging.MSCs were identified based on their ability to undergo differentiation into mesenchymal lineage cell types, including bone, cartilage, adipose tissue, muscle and tendon [4]. The differentiation capacity of MSCs was initially thought to be limited to their tissue of origin; however, studies have demonstrated that MSCs have the capacity to differentiate into cells of mesodermal, endodermal and ectodermal origins, at least in vitro [4,6-8]. The therapeutic application of MSCs was suggested from early observations in preclinical animal models of disease, in which transplanted MSCs homed to sites of inflammation within damaged tissues where some of the transplanted cells underwent differentiation to replace injured cells. However, it quickly became evident in a variety of disease models that the levels of improvement mediated by MSCs do not always correlate with the levels of cellular engraftment and differentiation observed. As such, differentiation may not be a primary mechanism by which MSCs mediate tissue repair. Rather, it has been widely reported that MSCs secrete bioactive levels of soluble factors (growth factors and cytokines) capable of paracrine regulation of diverse disease-associated processes, including ac

Abstract: the aim of this study was to evaluate whether intimate partner physical violence is a risk factor for late initiation of childcare in primary healthcare units (phcu). this cross-sectional study included 927 mothers and their infants less than six months of age seen at 27 phcu in rio de janeiro, brazil. the target outcome was delay in first visit to the service (at 60 days of age or later). interactions between intimate partner physical violence, maternal employment, and quality of prenatal care were explored using multivariate logistic regression. postpartum intimate partner physical violence was an independent risk factor for late initiation of children's healthcare when mothers had no formal occupation (or = 3.1, 95%ci: 1.5-6.3) or reported inadequate prenatal care (or = 4.8, 95%ci: 2.4-9.5). the results emphasize the need for better training of health professionals to detect cases of intimate partner violence during prenatal and pediatric care, which themselves are important steps for reducing such occurrence and thus promoting adequate maternal and child care.
