The Universidade Luterana do Brasil is a university which covers several states throughout Brazil. Its headquarters is located in the city of Canoas, in the state of Rio Grande do Sul . Within this state, Ulbra also has campuses in the cities of Cachoeira do Sul, Carazinho, Gravataí, Guaíba, Porto Alegre, Santa Maria, São Jerônimo and Torres. Apart from these cities, the university also has campuses in the states of Amazonas , Goiás , Pará , Rondônia , Tocantins and in the state of São Paulo.The university was founded by St. Paul's Lutheran Church of Canoas , and is affiliated with the Evangelical Lutheran Church of Brazil.Ulbra offers several majors, including medicine, which the university became entitled to offer after building its hospital, located within the university premises and currently serving the community of Canoas and neighbouring cities.They also maintain one of the largest automobile museum, with more than 200 vehicles. From Ford T to 2000 Corvette, even an Indy car piloted by Emerson Fittipaldi when he won Indianapolis 500 and its pace car. Wikipedia.

Initial attempts to cultivate mesenchymal stem cells (MSCs) were more successful from human than murine tissues. Methods for the in vitro expansion of murine MSCs were described more recently, but are now well established. Despite limitations such as a poor equivalence to be expected between cultured stem cells and their in vivo counterparts, MSC culture allows the expansion of a cell population capable of providing important information on the biology of stem cells and their therapeutic application. Murine MSCs may be obtained from the bone marrow and virtually from any other organ or tissue. This chapter describes the most widely used method, which involves the preparation of single-cell suspension followed by incubation for 1-3 days and removal of nonadherent cells. The adherent fraction is then expanded by continuous culture and may be maintained for prolonged periods of time. Source

Epidemiological studies for hazardous situations resulting from the risk of environmental and/or occupational exposure to miscellaneous chemicals present several difficulties. Biomonitoring of human populations can provide an early detection system for the initiation of cell dysregulation in the development of cancer, which would help develop an efficient prevention program. Recently, the cytokinesis-block micronucleus (CBMN) assay in lymphocyte cells has become an important tool for assessing DNA damage in exposed populations. This is the method of choice for population-based studies of occupational and/or environmental exposure to different agents. In this review, human populations exposed to coal, dyes, paints, organic solvents in a complex mixture, and others miscellaneous chemicals were analyzed. Data from 28 studies was evaluated in relation to the effect of complex mixture exposition on micronucleus (MN) frequency. Other biomarkers and the background factors were evaluated as well, such as gender, age, or smoking habit. Most of these studies (75%) showed a significant increase of micronucleated cells to exposed groups in relation to the control groups, besides chromosomal aberrations (CA), sister chromatid exchanging (SCE) and comet cells (comet assay). The studies from this review about miscellaneous chemicals exposures using CBMN assay have indicated some time and dose-dependent effects. Overall, the findings suggest that the responses resulting from exposure to complex mixtures are varied and complicated. However, they are also an important mechanism of DNA damage concerning disruption of metal ion homeostasis that may lead to oxidative stress, a state where increased formation of reactive oxygen species (ROS) overwhelms body antioxidant protection and subsequently could induce cancer. © 2016 Elsevier B.V.

Conventionally, in patients with completely edentulous mandibles, fixed prostheses have been supported by four or more implants. However, an alternative protocol employing three implants and immediate loading has been developed. The objective of the present study was to assess the rehabilitation of edentulous patients treated with a complete fixed mandibular prosthesis with immediate loading and supported by three implants. In this observational study, a total of 99 implants placed in 33 patients was evaluated after 18 months in use. Panoramic radiographs were digitized to measure bone loss at the mesial and distal surfaces of each implant. Mean peri-implant bone loss was 0.66 ± 0.51 mm for the left implant, 0.92 ± 0.61 mm for the central implant, and 0.82 ± 0.53 mm for the right implant. The bone loss observed around the distal implants was similar to that seen around the central implant, and there were no statistically significant differences in peri-implant bone loss between the three implant locations. There was no significant correlation between implant length and bone loss. The results were compatible with the peri-implant bone loss that has been described for prostheses of the same type supported by larger numbers of implants. The use of a complete fixed mandibular prosthesis with immediate loading supported by three implants proved to be an adequate option for the rehabilitation of edentulous patients. The protocol allowed simplification of treatment while maintaining similar bone loss to that reported for the same type of treatment supported by a larger number of implants. Source

The research investigates the matrix support in mental health in Primary Health Care in order to identify the guidelines, professional principles and values that permeate the process. The study used a qualitative approach with triangulation of techniques, and was performed with professionals from the Family Health Strategy. The results reveal a work process which is based on personalized relations, guided by the broadening of clinical practice and mediated by principles, such as inter-disciplinarity, bonding, comprehensiveness, accessibility, co-responsibilization and longitudinality. The values that underpin the relationship with the specialist are organized around the bond, trust and honesty. Difficulties in taking patients to Psychosocial Care Centers arise as obstacles to networking. The bond with the specialist, the structure of Family Health teams and the exchange of experiences and knowledge are identified as facilitating factors. The conclusions drawn are that the networking and the systematic and longitudinal support by specialists are key to decentralization in mental health. © 2015, Associacao Brasileira de Pos - Graduacao em Saude Coletiva.

Graduate-level physics curricula in many countries around the world, as well as senior-level undergraduate ones in some major institutions, include classical mechanics courses, mostly based on Goldstein's textbook masterpiece. During the discussion of central force motion, however, the Kepler problem is virtually the only serious application presented. In this paper, we present another problem that is also soluble, namely the interaction of Schwinger's dual-charged (dyon) particles. While the electromagnetic interaction of magnetic monopoles and electric charges was studied in detail some 40 years ago, we consider that a pedagogical discussion of it from an essentially classical mechanics point of view is a useful contribution for students. Following a path that generalizes Kepler's problem and Rutherford scattering, we show that they exhibit remarkable properties such as stable non-planar orbits, as well as rainbow and glory scattering, which are not present in the ordinary scattering of two singly charged particles. Moreover, it can be extended further to the relativistic case and to a semi-classical quantization, which can also be included in the class discussion. © 2015 IOP Publishing Ltd. Source
