Trajetória social de alunos de um curso pré-vestibular popular

The aim of the research that originated this article was the analysis of the social trajectory of students from a public preparatory course and the verification of their expectations about higher education. Data collection was based on a questionnaire with open and closed-ended questions and a semi-structured interview, based on the models used by Muzzetti (1997). Data were analyzed by the elaboration of thematic charts. Based on the researches conducted by Pierre Bourdieu (1997, 2007), this research concluded that the students understand that schooling is, besides being a viable alternative in the search for social ascension, the redeeming of social ills. Profession choice based on natural talent or divine gift generate expectations which attest the lack of knowledge about the school system by students and their parents, which is reinforced by the belief in opportunity equality.

Aparelho extrabucal como recurso auxiliar para alinhamento e nivelamento no tratamento orto cirúrgico de má oclusão classe III esquelética

When well indicated, the orthodontic surgical approach is the ideal treatment mean for Skeletal Class III adult patients. To improve facial esthetic results from orthognatic surgery, the leveling and alignment of maxillary dental arch must be achieved with minimal inclination and projection or even retro-inclination of anterior upper teeth. During a pre-surgical phase of 12 months, headgear bilateral force of 150 g/F was applied to the upper molars of a 22 years old male compliant patient with Class III skeletal malocclusion, to provide an upper teeth control of mesial tipping and projection during alignment and leveling. The ideal occlusal parameters required for surgical procedure were achieved without dental extractions permitting a total treatment period of 37 months. The outcomes remained stable over 3 years follow up after the removal of the appliance. The results indicate that, although headgear use depends greatly on patient compliance, when well indicated it is an interesting alternativetopromote dentaldecompensationon pre-surgical period, in order to allow surgical correction of skeletal Class III malocclusion.

Products for the treatment of inflammatory bowel disease: a patent review (2013-2014)

Introduction: Inflammatory bowel disease (IBD) consists of Crohn's disease, ulcerative colitis and an unspecific IBD. The unclear etiology of IBD is a limiting factor that complicates the development of new pharmacological treatments and explains the high frequency of refractory patients to current drugs, including both conventional and biological therapies. In view of this, recent progress on the development of novel patented products to treat IBD was reviewed.Areas covered: Evaluation of the patent literature during the period 2013 - 2014 focused on chemical compounds, functional foods and biological therapy useful for the treatment of IBD.Expert opinion: Majority of the patents are not conclusive because they were based on data from unspecific methods not related to intestinal inflammation and, when related to IBD models, few biochemical and molecular evaluations that could be corroborating their use in human IBD were presented. On the other hand, methods and strategies using new formulations of conventional drugs, guanylyl cyclase C peptide agonists, compounds that influence anti-adhesion molecules, mAbs anti-type I interferons and anti-integrin, oligonucleotide antisense Smad7, growth factor neuregulin 4 and functional foods, particularly fermented wheat germ with Saccharomyces cerevisiae, are promising products for use in the very near future.

Mastite infecciosa equina: uma visão geral da doença

Mastits is considered uncommon disease in mares. Streptococcus equi, Staphylococcus sp., Corynebacterium sp., Actinobacillus sp., Nocardia sp. and enterobacterias are major microorganisms involved in equine mammary infections. The disease is commonly related to traumatic lesions in mammary glands and teats. Edema, fibrosis, masses to palpation of glands, and viscous to seropurulent milk are mainly clinical signs observed in affected animals. The diagnosis is based on clinical exam of mammary glands and microbiological culture of the milk. There are no standard to use of indirect exams on diagnosis, including California Mastits Test and Somatic Cell Count. Systemic antimicrobials are recommended in therapy, based on previous “in vitro” susceptibility microbiological test. No specific control measures are indicated in equine mastits. The present study reviewed the mastits in mares, with emphasis to etiology, epidemiology findings, clinical manifestation, diagnosis, treatment and control aspects.

Characterization of Immobilized Biomass by Amplified rDNA Restriction Analysis (ARDRA) in an Anaerobic Sequencing-Batch Biofilm Reactor (ASBBR) for the Treatment of Industrial Wastewater

The performance of an anaerobic sequencing-batch biofilm reactor (ASBBR-laboratory scale- 14L) containing biomass immobilized on coal was evaluated for the removal of elevated concentrations of sulfate (between 200 and 3,000 mg SO4-2.L-1) from industrial wastewater effluents. The ASBBR was shown to be efficient for removal of organic material (between 90% and 45%) and sulfate (between 95% and 85%). The microbiota adhering to the support medium was analyzed by amplified ribosomal DNA restriction analysis (ARDRA). The ARDRA profiles for the Bacteria and Archaea domains proved to be sensitive for the determination of microbial diversity and were consistent with the physical-chemical monitoring analysis of the reactor. At 3,000 mg SO4-2.L-1, there was a reduction in the microbial diversity of both domains and also in the removal efficiencies of organic material and sulfate.

Divide to conquer: a complex pattern of biodiversity depicted by vertebrate components in the Brazilian Atlantic Forest

The identification of northern and southern components in different vertebrate species led researchers to accept a two-component hypothesis for the Brazilian Atlantic forest (BAF). Nevertheless, neither a formal proposal nor a meta-analysis to confirm this coincidence was ever made. Our main objective here was therefore to systematically test in how many vertebrate components the BAF could be divided by analysing existing empirical data. We used two approaches: (1) mapping and comparing the proposed areas of vertebrate endemism in the BAF and (2) analysing studies mentioning spatial subdivisions in distinct forest-dependent vertebrates within the biome, by the use of panbiogeography. The four large-scale endemism area components together with the six small-scale panbiogeographical ones allowed the definition of three BAF greater regions, subdivided into nine vertebrate components, latitudinally and longitudinally organized. Empirical time estimates of the diversification events within the BAF were also reviewed. Diversification of these vertebrates occurred not only in the Pleistocene but also throughout the Miocene. Our results confirm the BAF's complex history, both in space and time. We propose that future research should be small-scale and focused in the vertebrate components identified herein. Given the BAF's heterogeneity, studying via sections will be much more useful in identifying the BAF's historical biogeography.

Atendimentos decorrentes de queimaduras em serviços públicos de emergência no Brasil, 2009

O objetivo foi analisar os atendimentos por queimaduras em serviços de emergência, e fatores associados. Estudo transversal de 761 atendimentos coletados pelo Sistema de Vigilância de Violências e Acidentes em 2009. A maioria foi do sexo masculino (58,6%); adultos de 30 a 49 anos (23,1%) e crianças de 0 a 9 anos (23%). A residência foi o local de ocorrência mais frequente (62,1%), especialmente para crianças e mulheres; em seguida comércio, serviços, indústria e construção (19,1%), especialmente entre homens de 20 a 49 anos. Queimaduras no trabalho foram 29,1% do total. Uso de álcool chegou a 5,1%. Agentes causadores em todas as idades: substância quente (43,6%) e fogo/chama (24,2%); na faixa produtiva: substâncias químicas. As queimaduras entre 0 e 14 anos foram associadas com residência, substância e objeto quente e internação hospitalar; entre os de 15 a 49 anos associaram-se com fogo/chama e choque elétrico, via pública e alta da emergência. Estratégias de prevenção para crianças e trabalhadores devem ser implantadas.
