Crystallization behavior of structured lipids by chemical interesterification of lard and soybean oil

The aim of this study was to evaluate the crystallization behavior of binary mixtures of lard and soybean oil in different ratios and their respective structured lipids obtained by chemical interesterification. Crystallization kinetics and polarized light microscopy were used to analyze the mixtures before and after interesterification. The addition of soybean oil changed the lard crystallization, by the effect of the dilution. Crystal diameter increased, while the number of crystals decreased, as a function of temperature. Interesterification resulted in the formation of fewer crystals, with larger diameter in comparison with the original mixtures.FAPESPCoordenacao de Aperfeicoamento de Pessoal de Nivel Superior (CAPES)CNP

Permanent preservation, coverage area and use of the land in the hydrographic basin of the Almas River, microregion de Ceres, Goiás, Brazil

The aim of this study was to map the Permanent Preservation Areas (PPAs), as well as land cover and land use in the Almas River basin in Goiás, Brazil, based on geoprocessing. The results showed the remnants of the original vegetation are limited to fragments and occupy 32.52% of the area. Grassland is the dominant use, which is distributed throughout the area. Sugar cane and grains secondarily occupy other areas of the river basin. The mapped permanent preservation areas occupy an area of 1,182.22 km2, representing only 11.53% of the basins total area. The PPAs located on slopes with a 45º had a smaller area mapped and they were less affected by the use, whereas those of PPAs located in the springs and watercourses with larger area. Land use, disregarding APP areas, can endanger vital areas that, if degraded, represent damage to water resources.Este trabalho teve como finalidade elaborar o mapeamento das áreas de preservação permanente (APPs), e da cobertura e uso da terra na bacia hidrográfica do rio das Almas em Goiás, Brasil, com base no geoprocessamento. Os resultados revelaram que os remanescentes de vegetação original limitam-se a fragmentos e ocupam 37% da área. A pastagem é o uso dominante, o qual se distribui por toda área. A cultura da cana de açúcar e grãos ocupam, secundariamente, outras áreas da bacia hidrográfica. As áreas de preservação permanente mapeadas ocupam uma superfície de 1.182,22 km2 representando apenas 11,53% da área total da bacia. As APPs situadas em encostas com inclinação de 45º apresentaram menor área mapeada e foram menos afetadas pelo uso, enquanto que as de APPs situadas nas nascentes e cursos d’água, com maior área, foram as mais afetadas pelo uso indevido da terra. O uso da terra, desconsiderando as áreas de APPs, pode colocar em risco áreas importantes que, se degradadas, representam danos aos recursos hídrico

Implante Estético de Desfibrilador Submamário

Relata-se o caso de uma paciente do sexo feminino, de 37 anos de idade, com diagnóstico de doença de Chagas, cardiomiopatia dilatada e arritmias ventriculares. Queixava-se de problemas estéticos e funcionais decorrentes do implante de cardioversores-desfibriladores implantáveis, feito com a técnica habitual. Uma abordagem submamária foi escolhida em conjunto com a paciente. O procedimento foi realizado sem problemas e os testes de sensibilidade e estimulaçao dos eletrodos do átrio e do ventrículo direitos apresentaram parâmetros normais. No acompanhamento de seis meses, nao foram observadas complicaçoes cirúrgicas e a paciente referiu satisfaçao com o resultado estético e funcional

Genome wide scan for quantitative trait loci affecting tick resistance in cattle (Bos taurus × Bos indicus)

<p><b>Abstract</b></p> <p><b>Background</b></p> <p>In tropical countries, losses caused by bovine tick <it>Rhipicephalus (Boophilus) microplus</it> infestation have a tremendous economic impact on cattle production systems. Genetic variation between <it>Bos taurus</it> and <it>Bos indicus</it> to tick resistance and molecular biology tools might allow for the identification of molecular markers linked to resistance traits that could be used as an auxiliary tool in selection programs. The objective of this work was to identify QTL associated with tick resistance/susceptibility in a bovine F2 population derived from the Gyr (<it>Bos indicus</it>) × Holstein (<it>Bos taurus</it>) cross.</p> <p>Results</p> <p>Through a whole genome scan with microsatellite markers, we were able to map six genomic regions associated with bovine tick resistance. For most QTL, we have found that depending on the tick evaluation season (dry and rainy) different sets of genes could be involved in the resistance mechanism. We identified dry season specific QTL on BTA 2 and 10, rainy season specific QTL on BTA 5, 11 and 27. We also found a highly significant genome wide QTL for both dry and rainy seasons in the central region of BTA 23.</p> <p>Conclusions</p> <p>The experimental F2 population derived from Gyr × Holstein cross successfully allowed the identification of six highly significant QTL associated with tick resistance in cattle. QTL located on BTA 23 might be related with the bovine histocompatibility complex. Further investigation of these QTL will help to isolate candidate genes involved with tick resistance in cattle.</p

Panorama das Intervenções Coronárias Percutâneas em Oclusões Totais Crônicas em Centros Participantes do LATAM CTO Registry no Brasil

Background: Major advances have been seen in techniques and devices for performing percutaneous coronary interventions (PCIs) for chronic total occlusions (CTOs), but there are limited real-world practice data from developing countries. Objectives: To report clinical and angiographic characteristics, procedural aspects, and clinical outcomes of CTO PCI performed at dedicated centers in Brazil. Methods: Included patients underwent CTO PCI at centers participating in the LATAM CTO Registry, a Latin American multicenter registry dedicated to prospective collection of these data. Inclusion criteria were procedures performed in Brazil, age 18 years or over, and presence of CTO with PCI attempt. CTO was defined as a 100% lesion in an epicardial coronary artery, known or estimated to have lasted at least 3 months. Results: Data on 1196 CTO PCIs were included. Procedures were performed primarily for angina control (85%) and/or treatment of moderate/severe ischemia (24%). Technical success rate was 84%, being achieved with antegrade wire approaches in 81% of procedures, antegrade dissection and re-entry in 9%, and retrograde approaches in 10%. In-hospital adverse cardiovascular events occurred in 2.3% of cases, with a mortality rate of 0.75%. Conclusions: CTOs can be treated effectively in Brazil by using PCI, with low complication rates. The scientific and technological development observed in this area in the past decade is reflected in the clinical practice of dedicated Brazilian centersinfo:eu-repo/semantics/publishedVersio

Metagenomic analysis of a tropical composting operation at the São Paulo Zoo Park reveals diversity of biomass degradation functions and organisms.

Composting operations are a rich source for prospection of biomass degradation enzymes. We have analyzed the microbiomes of two composting samples collected in a facility inside the Sao Paulo Zoo Park, in Brazil. All organic waste produced in the park is processed in this facility, at a rate of four tons/day. Total DNA was extracted and sequenced with Roche/454 technology, generating about 3 million reads per sample. To our knowledge this work is the first report of a composting whole-microbial community using high-throughput sequencing and analysis. The phylogenetic profiles of the two microbiomes analyzed are quite different, with a clear dominance of members of the Lactobacillus genus in one of them. We found a general agreement of the distribution of functional categories in the Zoo compost metagenomes compared with seven selected public metagenomes of biomass deconstruction environments, indicating the potential for different bacterial communities to provide alternative mechanisms for the same functional purposes. Our results indicate that biomass degradation in this composting process, including deconstruction of recalcitrant lignocellulose, is fully performed by bacterial enzymes, most likely by members of the Clostridiales and Actinomycetales orders.FAPESP 2009/52030-5RCNPqCAPE
