OBJECTIVE:: To investigate the influence of candidate polymorphisms on chemokine receptor/ligand genes on HIV infection and AIDS progression (HIV/AIDS). DESIGN:: Fifteen polymorphisms of the CCR3, CCR4, CCR5, CCR6, CCR8, CXCR3, CXCR6, CCL20, CCL22 and CXCL10 genes were analysed in 206 HIV-positive subjects classified as rapid progressors (RPs; n?=?40), or non-RPs (NRPs; n?=?166) and in 294 HIV-seronegative subjects. METHODS:: The polymorphisms were genotyped using minisequencing. Genetic models were tested using binomial logistic regression; non-parametric multifactor dimensionality reduction (MDR) was used to detect gene–gene interactions. RESULTS:: The CCR3 rs3091250 [TT, adjusted odds ratio (AOR): 2.147, 95% confidence interval [CI] 1.076–4.287, P?=?0.030], CCR8 rs2853699?(GC/CC, AOR: 1.577, 95% CI 1.049–2.371, P?=?0.029), CXCL10 rs56061981?(CT/TT, AOR: 1.819, 95% CI 1.074–3.081, P?=?0.026) and CCL22 rs4359426?(CA/AA, AOR: 1.887, 95% CI 1.021–3.487, P?=?0.043) polymorphisms were associated with susceptibility to HIV infection. The CCL20 rs13034664 (CC, OR: 0.214, 95% CI 0.063–0.730, P?=?0.014) and CCL22 rs4359426?(CA/AA, OR: 2.685, 95% CI 1.128–6.392, P?=?0.026) variants were associated with rapid progression to AIDS. In MDR analyses revealed that the CXCL10 rs56061981 and CCL22 rs4359426 combination was the best model, with 57% accuracy (P?0.001) for predicting susceptibility to HIV infection. CONCLUSIONS:: Our results provide new insights into the influence of candidate chemokine receptor/ligand polymorphisms and significant evidence for gene–gene interactions on HIV/AIDS susceptibility.

My, what sharp teeth you have HOW the dinosaurs died out after ruling the planet for over 150m years was a mystery that consumed palaeontologists throughout much of the 20th century. These days it is mostly accepted that they were done in by the climatic after-effects of the impact of a giant asteroid, specifically the one that carved a vast crater 180km across near the Yucatan Peninsula in Mexico. Now the focus has shifted from how they died out to where they came from in the first place. In a paper just published in Current Biology, a team led by Max Langer at the University of São Paulo reports the excavation of four fossils that shed some intriguing light on two different aspects of that question. The fossils, found by Sergio Cabreira at the Lutheran University of Brazil, come from the Santa Maria formation in the south of the country. One of them, at 230m years in age, is one of the oldest dinosaur fossils ever found. Typically, such ancient finds are nothing more than bone fragments, but this specim A new fossil find in Brazil rewrites the history of the dinosaurs My, what sharp teeth you have HOW the dinosaurs died out after ruling the planet for over 150m years was a mystery that consumed palaeontologists throughout much of the 20th century.

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.

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.

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.

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.

Most clustering methods rely on central data structures and/or cannot cope with dynamically changing settings. Besides, these methods need some hints about the target clustering. However, issues related to the current use of Internet resources (distribution of data, privacy, etc.) require new ways of dealing with data clustering. In multiagent systems this is also becoming an issue as one wishes to group agents according to some features of the environment in order to have agents accomplishing the available tasks in an efficient way. In this paper we discuss the application of a clustering algorithm that is inspired by swarm intelligence techniques such as organization of bee colonies and task allocation among social insects. This application involves a complex task allocation scenario, the RoboCup Rescue, where tasks with different characteristics must be allocated to agents with different capabilities. Our results have shown that clustering agents is effective in this scenario as agents act in a more coordinated way. © 2011 Elsevier B.V.

This study evaluated health education, and particularly popular health education, as a methodological approach used in the Brazilian basic healthcare network and in the Family Health Strategy, a family health program of the Brazilian government. The literature on health education, educational practices in healthcare services, and popular health education was reviewed. We found that educational practices in healthcare services follow traditional methods and do not prioritize the establishment of links between healthcare workers and the population. To be consolidated as an educational practice, popular health education should be incorporated into the routine of healthcare services. For this purpose, the preparation of healthcare workers should focus on actions to promote collective health and critical reflections on healthcare teaching and learning by all the individuals involved in these processes.

Evidence has suggested that a significant proportion of children and adolescents has high levels of total cholesterol. To estimate the prevalence of hypercholesterolemia and associated factors in 07-12 year-old school children. School based cross sectional study of a random sample of 1,294 07-12 year-old school children from Caxias do Sul/RS, Brazil. The students answered an interview with information on socioeconomic status, food habits, and physical and leisure activities. Total cholesterol, cardiorespiratory fitness, body mass and height were measured to calculate body mass index. For the data treatment, univariate, bivariate, and multivariate analyzes were used. The multivariate analysis identified that individuals from high socioeconomic level (OR: 1.70; CI: 1.05-2.75), of female gender (OR: 1.32; CI: 1.03-1.67), and overweight (OR: 1.40; IC: 1.10-1.77) had increased chances of having increased total cholesterol (> 3rd tercile). High total cholesterol levels on 07-12 year-old school children are associated with high socioeconomic level, female gender, and overweight. Encouraging an active life style and appropriate dietary habits can help control cholesterol levels and reduce risk factors.

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.
