Descriptive study of homophobia and vulnerability to HIV/Aids of the transvestites in the Metropolitan Region of Recife, Brazil

Abstract: This study sought to ascertain the vulnerabilities to HIV/Aids of transvestites of the Metropolitan Region of Recife. The Respondent-Driven Sampling (RDS) method was selected for data collection. Among the 110 transvestites, high indices of homophobia were found in locations such as: security services, work facilities, family and religious environments, neighborhood, school, stores, leisure spaces, and healthcare services. Among the situations of violence experienced, the predominant cases involved verbal aggression (81.8%) and physical aggression (68.2%). The HIV test carried out at some stage in their lives was reported by 84.4% of the subjects. A high level of knowledge of the forms of HIV prevention and transmission was detected. The majority of the transvestites began their sexual activity before 15 years of age without condom use. It was seen that in the context of the HIV/Aids epidemic, the strategies for health promotion can only be effective if factors for enhancing the understanding of the vulnerability to HIV/Aids, such as homophobia, are considered.

Eosinophilic granuloma in the jaws.

Abstract: Eosinophilic granuloma is the most common expression of Langerhans cell histiocytosis and corresponds with typical bone lesions. This disease is of importance to dental professionals because early clinical signs can occur in the jaw and can cause extensive destruction of the periodontal tissues. Pathological fracture is an unusual finding. The purpose of this case report is to describe a case of eosinophilic granuloma in a 28-year-old black man who initially appeared with intense pain from a pathological mandibular fracture.

Real Time Ray Tracing for Augmented Reality

Abstract: This paper introduces a novel graphics rendering pipeline applied to augmented reality, based on a real time ray tracing paradigm. Ray tracing techniques process pixels independently from each other, allowing an easy integration with image-based tracking techniques, contrary to traditional projection-based rasterization graphics systems, e.g. OpenGL. Therefore, by associating our highly optimized ray tracer with an augmented reality framework, the proposed pipeline is capable to provide high quality rendering with real time interaction between virtual and real objects, such as occlusions, soft shadows, custom shaders, reflections and self-reflections, some of these features only available in our rendering pipeline. As proof of concept, we present a case study with the ARToolKitPlus library and the Microsoft Kinect hardware, both integrated in our pipeline. Furthermore, we show the performance and visual results in high definition of the novel pipeline on modern graphics cards, presenting occlusion and recursive reflection effects between virtual and real objects without the latter ones needing to be previously modeled when using Kinect. Furthermore, an adaptive soft shadow sampling algorithm for ray tracing is presented, generating high quality shadows in real time for most scenes.

Small IncQ1 and Col-Like Plasmids Harboring bla KPC-2 and Non-Tn 4401 Elements (NTE KPC -IId) in High-Risk Lineages of Klebsiella pneumoniae CG258.

Abstract: A retrospective genomic study led to the identification of two carbapenem-resistant K. pneumoniae isolates (KPN535 and KPC45) carrying bla KPC-2 genes on non-conjugative plasmids.….
