    The Roco family consists of multidomain Ras-GTPases that include LRRK2, a protein mutated in familial Parkinson's disease. The genome of the cellular slime mold Dictyostelium discoideum encodes 11 Roco proteins. To study the functions of these proteins, we systematically knocked out the roco genes. Previously described functions for GbpC, Pats1, and QkgA (Roco1 to Roco3) were confirmed, while novel developmental defects were identified in roco4- and roco11-null cells. Cells lacking Roco11 form larger fruiting bodies than wild-type cells, while roco4-null cells show strong developmental defects during the transition from mound to fruiting body; prestalk cells produce reduced levels of cellulose, leading to unstable stalks that are unable to properly lift the spore head. Detailed phylogenetic analysis of four slime mold species reveals that QkgA and Roco11 evolved relatively late by duplication of an ancestor roco4 gene (later than approximately 300 million years ago), contrary to the situation with other roco genes, which were already present before the split of the common ancestor of D. discoideum and Polysphondylium pallidum (before approximately 600 million years ago). Together, our data show that the Dictyostelium Roco proteins serve a surprisingly diverse set of functions and highlight Roco4 as a key protein for proper stalk cell formation. PMID:20348387

    Purpose: The authors use reduced-order constrained optimization (ROCO) to create clinically acceptable IMRT plans quickly and automatically for advanced lung cancer patients. Their new ROCO implementation works with the treatment planning system and full dose calculation used at Memorial Sloan-Kettering Cancer Center (MSKCC). The authors have implemented mean dose hard constraints, along with the point-dose and dose-volume constraints that the authors used for our previous work on the prostate.Methods: ROCO consists of three major steps. First, the space of treatment plans is sampled by solving a series of optimization problems using penalty-based quadratic objective functions. Next, an efficient basis for this space is found via principal component analysis (PCA); this reduces the dimensionality of the problem. Finally, a constrained optimization problem is solved over this basis to find a clinically acceptable IMRT plan. Dimensionality reduction makes constrained optimization computationally efficient.Results: The authors apply ROCO to 12 stage III non-small-cell lung cancer (NSCLC) cases, generating IMRT plans that meet all clinical constraints and are clinically acceptable, and demonstrate that they are competitive with the clinical treatment plans. The authors also test how many samples and PCA modes are necessary to achieve an adequate lung plan, demonstrate the importance of long-range dose calculation for ROCO, and evaluate the performance of nonspecific normal tissue (“rind”) constraints in ROCO treatment planning for the lung. Finally, authors show that ROCO can save time for planners, and they estimate that in the clinic, planning using their approach would save a median of 105 min for the patients in the study.Conclusions: New challenges arise when applying ROCO to the lung site, which include the lack of a class solution, a larger treatment site, an increased number of parameters and beamlets, a variable number of beams and beam arrangement, and

  3. Obituary -- Enrique Chavira Navarrete

    2001-04-01

    During the twentieth century, Mexican astronomical observatories migrated Tonantzintla and from there to the selected mountain sites of San Pedro Mártir and Cananea. In Tonantzintla Mexican astronomy progressed from cosmography to astrophysics. There, during the fifties and sixties, Guillermo Haro used the Schmidt camera to place México in the astronomical map. Instrumental to this process was Enrique Chavira, whose scientific life almost exactly matched the second half of the century which has just finished, going from the pioneer times of the Tonantzintla Astrophysical Observatory to the fully developed Mexican astronomy of the dawn of the XXI century. Enrique Chavira died unexpectedly 38 days before the turn of the century. Even though his heart had shown past weaknesses, his daily presence in the corridors of the Tonantzintla Institute somehow led us to believe he would always be here. Chavira was the most senior of the astronomers at Tonantzintla and, though he never entered the decision circles, he always had an opinion, frequently ironic, about the main problems of the Instituto. I do remember more than one occasion Alfonso Serrano asking for the advice of Chavira, seeking the experience of the former assistant of Don Guillermo Haro. Born and raised in México City, Chavira eventually moved to Puebla, the closest large city to Tonantzintla, following the steps of Mexican observational astronomy. Without concluding his formal studies, Chavira managed to adjudicate for himself the title of ``astrónomo'', earning it with his skillful handling of the Schmidt camera and the photographic plates. Over the years he took over 8000 astronomical plates, which is a little more than half of the precious Tonantzintla collection. Even though Chavira was aware of his limitations, his ability in photographic astronomy made him a recognized astronomer. The list of his co-authors includes, apart from Guillermo Haro, other renamed astronomers like Manuel Peimbert, Luis

  4. Enriques Surfaces, Analytic Discriminants, and Borcherds's Φ Function

    NASA Astrophysics Data System (ADS)

    Jorgenson, Jay; Todorov, Andrey

    In [Bor 96], Borcherds constructed a non-vanishing weight 4 modular form Φ on the moduli space of marked, polarized Enriques surface of degree 2 by considering the twisted denominator function of the fake monster Lie algebra associated to an automorphism of order 2 of the Leech lattice fixing an 8-dimensional subspace. In [JT 94] and [JT 96], we defined and studied a meromorphic (multi-valued) modular form of weight 2, which we call the K3 analytic discriminant, on the moduli space of marked, polarized, K3 surfaces of degree 2d; in certain cases, including when , where pk are distinct primes, our meromorphic form is actually a holomorphic form. Our construction involves a determinant of the Laplacian on a polarized K3 surface with respect to the Calabi-Yau metric together with the L2 norm of the image of the period map with respect to a properly scaled holomorphic two form. Since the universal cover of any Enriques surface is a K3 surface, we can restrict the K3 analytic discriminant to the moduli space of degree 2 Enriques surfaces. The main result of this paper is the observation that the square of our degree 2 analytic discriminant, viewed as a function on the moduli space of degree 2 Enriques surfaces, is equal to the Borcherd's Φ function, up to a universal multiplicative constant. This result generalizes known results in the study of generalized Kac-Moody algebras and elliptic curves, and suggests further connections with higher dimensional Calabi-Yau varieties, specifically those which can be realized as complete intersections in some, possibly weighted, projective space.

    Scientific knowledge and philosophic knowledge have an ethical responsibility that should not be disregarded. This observation made by scholar-philosophers such as Henri Poincaré and Federigo Enriques has experienced an importance of which 20(th) century epistemology has been unaware. It is important to relaunch this observation in the name of older values: equality, democracy, openness, research without dogmatic boundaries. The analysis of the work of Enriques enables us to grasp the stakes of such an endeavor. PMID:21567305

    The purpose of the present study was to estimate emissions of some pollutants (CO, NO(X), HC, SO(X), and PM) in diesel fleet due to the addition of biodiesel in different blends, as well as to assess atmospheric pollutant concentrations in the metropolitan area of Porto Alegre (MAPA). The methodology was based on inventories from mobile sources based on US EPA's technical report. Regarding air quality the following parameters were determined: PM(10), PM(2.5), CO, NO(X), O(3), SO(2), HC and PAHs. The results showed a decrease for emissions PM, CO, and HC, and a slight increase for NO(X). The characterization of atmospheric pollutants in the metropolitan area of Porto Alegre showed that they are influenced by mobile sources, particularly diesel vehicles. The diagnosis of ratios analysis that was applied to facilitate the identification of sources of PAHs, indicated an influence of diesel oil. PMID:22886159

  9. Peroxyacetyl nitrate and peroxypropionyl nitrate in Porto Alegre, Brazil

    Grosjean, Eric; Grosjean, Daniel; Woodhouse, Luis F.; Yang, Yueh-Jiun

    For 41 days between 25 May 1996 and 27 March 1997, peroxyacetyl nitrate (PAN) and peroxypropionyl nitrate (PPN) have been measured by electron capture gas chromatography at Santa Rita near Porto Alegre, RS, Brazil, where light-duty vehicles used either ethanol or a gasoline-MTBE blend. Daily maximum concentrations ranged from 0.19 to 6.67 ppb for PAN and 0.06 to 0.72 ppb for PPN. Linear regression of maximum PPN vs. maximum PAN yielded a slope of 0.105±0.004 ( R2=0.974). Diurnal variations of ambient PAN often followed those of ozone with respect to time of day but not with respect to amplitude. This was reflected in the large relative standard deviations associated with the study-averaged PAN/ozone concentration ratio, 0.037±0.105 (ppb/ppb, n=789) and the maximum PAN/maximum ozone concentration ratio, 0.028±0.015 (ppb/ppb, range 0.005-0.078, n=41). On several days PAN accounted for large fractions of the total ambient NO x in the late morning and afternoon hours, e.g., PAN/NO x⩽0.58 and PAN/(NO x-NO) ⩽0.76 on 27 March 1997. The amount of PAN lost by thermal decomposition (TPAN) was comparable in magnitude to that present in ambient air. The ratios TPAN/(PAN+TPAN) were up to 0.53, 0.67 and 0.64 during the warm afternoons of 25, 26 and 27 March 1997, respectively. The highest calculated value of TPAN was 5.6 ppb on 27 March 1997. On that day the 24 h-averaged value of TPAN (1.01 ppb) was nearly the same as that of PAN (1.09 ppb). Using computer kinetic modeling (SAPRC 97 chemical mechanism) and sensitivity analysis of VOC incremental reactivity, we ranked VOC present in Porto Alegre ambient air for their importance as precursors to PAN and to PPN. Using as input data the averages of VOC concentrations measured in downtown Porto Alegre during the ca. 1 yr period March 1996-April 1997, we calculated that the most important precursors to PAN and PPN were the SAPRC 97 model species ARO2 (which includes the aromatics xylenes, trimethylbenzenes, ethyltoluenes, etc

  12. "A century of civilization under the influence of eugenics": Dr. Enrique Diego Madrazo, socialism and scientific progress.

    Cleminson, Richard

    2006-01-01

    This article discusses the thought of one of the pioneers of eugenics in Spain, Dr. Enrique Diego Madrazo. In particular, it analyses his 1930 essay Un siglo de civilización bajo la influencia eugenésica [A Century of Civilization under the Influence of Eugenics], as the most explicit work on the eugenic utopia he advocated. This work, because of its breadth, was also one of the most extensive and detailed accounts of the steps to be taken towards the eugenic society that was produced. The present analysis of his work assesses the degree to which his thought, which has been described as "utopian socialist", in fact corresponded to that epithet, given the politically authoritarian nature and the gender bias of some aspects of his one-hundred year plan for the creation of a eugenic society. The article also places Madrazo's thought in the context of his time and other national currents of eugenic thought. PMID:17214140

    Porto Alegre is the capital and largest city in the Brazilian state of Rio Grande do Sul in Southern Brazil with approximately 1.5 million inhabitants. The city lies on the eastern bank of the Guaiba Lake, formed by the convergence of five rivers and leading to the Lagoa dos Patos, a giant freshwater lagoon navigable by even the largest of ships. This river junction has become an important alluvial port as well as a chief industrial and commercial centre. However, this strategic location resulted in severe damage because of its exposure to flooding from the river system, affecting the city in the years 1873, 1928, 1936, 1941 and 1967. In order to reduce flood risk, a complex system of levees and pump stations was implemented during 1960s and 1970s. Since its construction, not a single large flood event occurred. However, in recent years, the levees in the downtown region of Porto Alegre were severally criticized by city planners and population. Several projects have been proposed to demolish the Mauá Wall due to the false perception of lack of flood risk. Similar opinions and reactions against flood infrastructure have been observed in other cities in Brazil, such as Itajaí and Blumenau, with disastrous consequences. This paper illustrates how the perception of flood risk in Porto Alegre has changed over recent years as a result of flood infrastructure, and how such changes in perceptions can influence water management decisions.

  19. Report: citizen participation as a part of integrated solid waste management: Porto Alegre case.

    This study presents the effects of citizen participation on integrated solid waste management. Porto Alegre was chosen as the area of study since its system is a good example for developing countries, based on the partnership between local government and the former scavengers' association that implements selective collection in the city. A life-cycle approach was used to estimate environmental loadings and economic costs based on solid waste generation, and a survey assessment tool was used to analyse social aspects. The results showed a decrease in environmental and economic impacts in the current situation, allowing Porto Alegre to have one of the most affordable integrated solid waste management systems in Brazil. The survey assessment pointed out that public campaign changed the perceptions and practices of most of Porto Alegre's citizens regarding solid waste management. On the other hand, it also pointed out that citizens need more education to increase their participation. Therefore, more research is needed to increase cooperation among all stakeholders, improve citizen participation, and consequently, further decrease the environmental impacts and economic costs.

    SUMMARY Pityriasis versicolor is the most common of the diseases caused by Malasseziayeasts. The aim of this study is to determine the prevalence of pityriasis versicolor and its etiological aspects in the metropolitan area of Porto Alegre, Brazil. A retrospective crosssectional study with data from patients of a reference hospital from 1996 to 2011 was performed. Collected data included: date, age, gender, ethnicity, anatomical region of lesion and the direct mycological examination results. Among the positive results in the direct mycological examination, 5.8% (2,239) were positive for pityriasis versicolor. The angular coefficient (B) was -0.3%/year, showing a decrease over the years. The disease was more prevalent in men (7.1% of men versus 5.1% of women that underwent the direct mycological examination); younger age (median 31 years old); "pardo" and black people (3.7% more than expected in the sample); trunk (73.44% of the affected anatomic sites). Lesions in rare sites (groin, genitals, legs, feet and hands) were also observed in this study. In conclusion, due to the decrease in the prevalence of pityriasis versicolor, long-term epidemiological studies in the metropolitan area of Porto Alegre, Brazil, are needed to continue the monitoring of this disease.

    This article is the product of research undertaken in the city of Porto Alegre, in the Brazilian state of Rio Grande do Sul. The goal is to bring to light and discuss a little known phenomenon - attempted suicide by the elderly. Under-reporting of suicide attempts among this population makes it difficult to place this serious public health problem on the political agenda. As part of this study, we interviewed not only elderly persons who had attempted suicide, but also their family members and mental health and emergency and urgent service professionals. These interviews took place during the course of 2014. From a textual discourse analysis of the various reports, there emerged a category we will call Convergence and Non-Convergence, which deals with the relationship between the elderly population's need for care and the healthcare model in use. This study uses three short stories of individuals to question the biomedical model of serving risk situations, stressing the concept of an Expanded Clinic to provide integrated healthcare. This concept focuses on the different types of care and the uniqueness of each user, which often the biomedical model neglects. This study also highlights the need to develop a line of care for the elderly, with investments in continued education about active aging and care in times of crises, articulating a cross-sectorial network.

    The untold story of the Maritime Maya from the ancient port site Vista Alegre, is being written for the first time using a multidisciplinary effort that aims to reconstruct the environmental and morphological history of the site. Vista Alegre is located on the north-eastern tip of the Yucatan peninsula, on the ancient Maritime Maya trade routes. This strategic point between the Caribbean Sea and the Gulf of Mexico, offers an ideal setting for this kind of research, which will add to the general Maritime Maya history. The multidisciplinary effort is part of a larger project called "Costa Escodida". The project's main goals are to learn how the ancient inhabitants adapted to the environment, and to understand how this coastal site was integrated into broader maritime trade routes. The portion of the research presented here concentrates on the sites geomorphology and climate during the past 2-3000 years through the multiproxy analysis of marine sediment core and surface samples combined with archaeological data. This study aids our understanding of the site's possible functions, the environmental challenges the local inhabits contended with, and the identification of ancient harboring locations. The site was inhabited from the 9th century B.C until the mid 16th century A.D., with an apparent two century abandonment phase from the mid 7th to 9th century A.D. According to the results, five depositional phases can be recognized, and the related shoreline reconstruction shows a general trend of a flooded terrestrial landscape. This 'flooding' relates well to relative sea-level curves published in the region. Continued analysis of results from the research, and future research activities, may make it possible to recognize hurricane proxies in the sediment, locate underwater manmade seafaring artifacts and facilities, determine the range of economic opportunities for past inhabitants and quantify the availability of potable water sources.

    Few population-based cohort studies have been established in Dentistry and this is especially true for Latin America. We conducted a population-based prospective study focusing on oral health in Porto Alegre, south Brazil, and herein we describe its methodology and discuss directions for further research. The cohort was established in 2001 using a multistage probability sample of 1,465 toothed and 121 edentulous subjects. A 5-year follow-up was performed in 2006 that included 755 individuals. The main aim of this study was to determine the pattern and risk factors for periodontal disease progression and tooth loss incidence. A full-mouth protocol was used including periodontal assessments at six sites per tooth. Primary outcomes were periodontal attachment loss and tooth loss. Oral mucosal lesions, dental plaque, gingivitis, supragingival calculus, probing depths, gingival recession, and dental caries were also assessed. This is the first population-based cohort study to focus on periodontal disease in Latin America. Findings will contribute to our understanding of the epidemiology of periodontal disease and provide valuable data for the planning and implementation of preventive and therapeutic strategies.

    This paper investigated the occurrence and impact of stressing events for 297 low- income children/adolescents (both sexes; 7-16 years, M =11.22; SD = 2.13) in the city of Porto Alegre. Group 1 (G1) consisted of 142 participants (living with their families) and Group 2 (G2) of 155 institutionalized individuals. All were individually interviewed and answered the Stressing Events Inventory for Children/Adolescents. The most frequent stressing events for the sample were: follow orders given by the parents (85.2%); quarrels with friends (72.9%); death of relatives (71.8%); failure at school (69.2%); and rivalry of siblings (68%). Student's t-test revealed significant difference between groups (p <0,001) regarding the occurrence of stressing events, G2 presented higher scores (M = 26.79; SD = 8.67) than G1 (M = 19.16; SD = 9.37). The events that caused the greatest impact upon the studied group were: death of parents and friends, rape, rejection by relatives and violence. There was no significant difference between sexes (p>0.05). The high frequency and strong impact of stressing events reveal the situation of social and familiar vulnerability, presence of violence and lack of resources in the whole group. PMID:19197420

    In the acoustic study of the Metropolitan Cathedral of Porto Alegre, RS, Brazil, initially background noise and reverberation time were measured. A digital model was built using acoustic simulation software AcustaCadd, applying the values of the measured reverberation time. Then reverberation time, speech intelligibility, and geometric acoustics were analyzed. As a result the Project of Acoustic Conditioning was developed to correct the high reverberation time, by increasing absorption with the installation of 65000 m of panels of glass wool (100 mm, 60 kg/m). Advantage was taken of existing details in the plaster to embed the panels in the walls. Also the volume of the choir and of the lateral balcony to the altar was reduced and the interior of this was covered with the same glass wool. Special care was taken to minimize alterations to the architectural characteristics of the place, because it is a construction of historical importance. The measured values of background noise were also analyzed and appropriate acoustic isolation considered. The final measure of the reverberation time showed an average reduction of 5 seconds and better speech intelligibility, long demanded by the users. [Work supported by FAIR/FUNDATEC, BR; IUCC-US, SP.

    Violence is of major importance in the health profile of Brazilian metropolitan areas and should be treated as a public health problem. Spatial analysis methods can be highly useful for the surveillance and prevention of violence. This paper analyzes the spatial distribution of victims' place of residence in relation to the main causes of violent death in Porto Alegre (1996) in order to identify vulnerable areas. For motor vehicle accidents, homicides, and suicide, the victim's place of residence was pinpointed using the municipal Geographic Information System. The point patterns of health events and population density were analyzed using a Kernel smoother, visually compared. Some areas with higher concentration of events are similar to population distribution but differ from each other in the remaining high concentration areas, thus indicating specific micro-areas at risk. Areas of higher homicide risk are mainly located on the periphery of the more urbanized area, with worse socioeconomic conditions. Motor vehicle accidents are concentrated in areas that are simultaneously commercial and residential and are traversed by streets with heavy traffic. Suicide deaths are more evenly distributed over the territory. Identification of risk areas provides meaningful information for developing preventive and health promotion measures focusing on the events for which health policies may play a central role.

    Shatter cones are one of the most widely recognized pieces of evidence for meteorite impact events on Earth, but the process responsible for their formation is still debated. Evidence of melting on shatter cone surfaces has been rarely reported in the literature from terrestrial impact craters but has been recently observed in impact experiments. Although several models for shatter cones formation have been proposed, so far, no one can explain all the observed features. Shatter cones' from the Vista Alegre impact structure, Brazil, formed in fine-grained basalt of the Jurassic-Cretaceous Serra Geral Formation (Paraná large igneous province). A continuous quenched melt film, consisting of a crystalline phase, mica, and amorphous material, decorates the striated surface. Ultracataclasites, containing subrounded pyroxene clasts in an ultrafine-grained matrix, occur subparallel to the striated surface. Several techniques were applied to characterize the crystalline phase in the melt, including Raman spectroscopy and transmission electron microscopy. Results are not consistent with any known mineral, but they do suggest a possible rare or new type of clinopyroxene. This peculiar evidence of melting and cataclasis in relation with shatter cone surfaces is interpreted as the result of tensile fracturing at the tip of a fast propagating shock-induced rupture, which led to the formation of shatter cones at the tail of the shock front, likely during the early stage of the impact events.

    This article focuses on the magnitude of work-related deaths in Porto Alegre, the capital of Rio Grande do Sul State, Brazil. Death certificates were used to investigate 159 cases, or 18% of the 877 deaths from external causes in 1992. Some 31 cases were identified. The principal cause of death among these workers was homicide, with 58% of cases (15 from fire arms and 3 from knives), followed by traffic accidents, with 29% (5 motor vehicle collisions and 4 pedestrians run down by motor vehicles). Of these 31 deaths, 17 were workers from the formal labor market, of whom 11 did not fit into the regular reporting procedures for work-related accidents. The other 14 deaths were of workers from the informal labor market (7), individuals involved in illicit activities (6), and unknown (1), in which cases reporting as work-related accidents was also inappropriate. These data suggest negligence by the public sector in dealing with this issue and the fact that official statistics fail to reflect the reality of daily working conditions. The authors conclude that health surveillance requires other data collection mechanisms besides those used by the Social Welfare System, so as to include all actual risks related to work situations.

    In the past two decades the members of the genus Enterococcus have emerged as important nosocomial pathogens worldwide. In the present study, we evaluated the antimicrobial resistance and genotypic characteristics of 203 Enterococcus spp. recovered from different clinical sources from two hospitals in Porto Alegre, Rio Grande do Sul, Brazil. The species were identified by conventional biochemical tests and by an automated system. The genetic diversity of E. faecalis presenting high-level aminoglycoside resistance (HLAR) was assessed by pulsed-field gel electrophoresis of chromosomal DNA after SmaI digestion. The E. faecalis was the most frequent specie (93.6%), followed by E. faecium (4.4%). The antimicrobial resistance profile was: 2.5% to ampicillin, 0.5% to vancomycin, 0.5% teicoplanin, 33% to chloramphenicol, 2% to nitrofurantoin, 66.1% to erythromycin, 66.5% to tetracycline, 24.6% to rifampicin, 30% to ciprofloxacin and 87.2% to quinupristin-dalfopristin. A total of 10.3% of the isolates proved to be HLAR to both gentamicin and streptomycin (HLR-ST/GE), with 23.6% resistant only to gentamicin (HLR-GE) and 37.4% only to streptomycin (HLR-ST). One predominant clonal group was found among E. faecalis HLR-GE/ST. The prevalence of resistance among beta-lactam antibiotics and glycopeptides was very low. However, in this study there was an increased number of HLR Enterococcus which may be spreading intra and inter-hospital. PMID:24031416

    OBJECTIVE To analyze the prevalence of depression in older adults and associated factors. METHODS Cross-sectional study using a stratified random sample of 621 individuals aged ≥ 60 from 27 family health teams in Porto Alegre, RS, Southern Brazil, between 2010 and 2012. Community health agents measured depression using the 15-item Geriatric Depression Scale. Scores of ≥ 6 were considered as depression and between 11 and 15 as severe depression. Poisson regression was used to search for independent associations of sociodemographic and self-perceived health with both depression and its severity. RESULTS The prevalence of depression was 30.6% and was significantly higher in women (35.9% women versus 20.9% men, p < 0.001). The variables independently associated with depression were: female gender (PR = 1.4, 95%CI 1.1;1.8); low education, especially illiteracy (PR = 1.8, 95%CI 1.2;2 6); regular self-rated health (OR = 2.2, 95%CI 1.6;3.0); and poor/very poor self-rated health (PR = 4.0, 95%CI 2.9;5.5). Except for education, the strength of association of these factors increases significantly in severe depression. CONCLUSIONS A high prevalence of depression was observed in the evaluations conducted by community health agents, professionals who are not highly specialized. The findings identified using the 15-item Geriatric Depression Scale in this way are similar to those in the literature, with depression more associated with low education, female gender and worse self-rated health. From a primary health care strategic point of view, the findings become still more relevant, indicating that community health agents could play an important role in identifying depression in older adults.

    Abuse of the elderly is a form of violence to come to the public's attention. Dental professionals are in an ideal position to identify physical abuse. The aim of this study was to assess the prevalence of elderly abuse and analyze the database of injury reports that can be identified by dental teams. A documentary analysis study developed by the Elderly Protection Police Station of Porto Alegre, Rio Grande do Sul, was carried out. The information used came from 2,304 complaints filed at the aforementioned institution between the years of 2004 and 2006. The records of abuse are categorized as injury, neglect, mistreatment, theft, financial abuse, threat, disturbing the peace, atypical fact, and others. The injuries that could be identified by the dental team were classified according to the injury's location in the area of the head, face, mouth and neck. Descriptive analysis was performed, and chi-square tests were used to evaluate the distributions of the types of elder abuse in relation to sex and age. The most frequent of the different types of abuse was theft, with a prevalence of 17.8%, followed by disturbing the peace at 11.8%. Disturbing the peace, threat, and bodily injury were significantly associated with women. Elder abuse among women and men declines with age. The prevalence of head injury was 25% of the total injuries, most often in females, and in those aged < 70 years. Based on these results, it is necessary that the dental team observe the elderly person's appearance for suspicious physical signs. PMID:23657487

    At the northeast tip of the Yucatan Peninsula - where the Caribbean meets the Gulf - lies the ancient Maya port site of Vista Alegre. The inhabitants of this site, much like the people living nearby today, were forced to contend with the challenging coastal environment of Laguna Holbox. The sediment-rich, low gradient of the north coast presents a contrasting landscape compared to the Caribbean coast, where water resources are of much larger magnitude and evident in the extensive systems of cenotes (sinkholes) and underground rivers that supported pre-Columbian sites along this eastern rocky sediment-poor coastline. For past inhabitants the north coast was a mosaic of low-lying, non-arable zones where access to potable water was a challenge for inhabitants well into the 20th century. By bringing together scholars from the fields of archaeology, coastal ecology, geoarchaeology, and hydrogeology, the Proyecto Costa Escondida is focusing on the dynamic relationship between the Maya and their coastal landscape over the past 3000 years. To date we have collected 12 manual push-cores from the shallow waters surrounding Vista Alegre, which have been analyzed at 1 cm resolution using standard methods for Loss on Ignition (LOI), δ18Ocarb and δ13Ccarb of bulk carbonate, granulometry, micropalentology, and AMS radiocarbon dating. In addition to have baseline comparative data, we have conducted near-shore and terrestrial coastal ecological surveys along with the mapping of coastal water salinity and temperatures in the dry and wet seasons. Overall, the chemical proxies, lithology, and paleosalinity model reconstructed to date reveal four onlapping parasequences representing an overall transgression of the coastline with strong seasonality of water chemistry that has been changing under the control of rising sea levels over the past 3000 years. The sedimentation rate and timing of the transition to marine is in reasonable agreement with local sea level curves meaning that the

    Abstract: Generally, natural environments have been transformed into small forest remnants, with the consequent habitat loss and species extinction. The North Paraná State is not an exception, since only 2 to 4% of the original ecosystem occurs in small fragments of Stational Semidecidual Forest. We studied the species richness and abundance of bats in two forest fragments from the Fazenda Congonhas, in Rancho Alegre city, Parana State, Brazil. Four samplings were undertaken in a legally protected native area (107.8 ha) and in a reforested area (11.8 ha) between April 2007 and March 2008. Samplings began at nightfall and lasted six hours,during two consecutive nights in each location. The individuals were captured using eight mist nets, with the same capture effort in both environments. A total of 397 individuals, 14 species and 10 genera were captured in the native area; while in the reforested area, 105 individuals, six species and four genera. Artibeus lituratus was the most common species in both fragments (n = 328, 65.3%), followed by Artibeus fimbriatus (n = 44, 8.8%) and Artibeus jamaicensis (n = 30, 6.0%). Other species including Platyrrhinus lineatus, Carollia perspicillata, Sturnira lilium, Chrotopterus aurintus, Desmodus rotundus, Michronycteris megalotis, Phyllostomus hastatus, Phyllostomus discolor, Myoti levis, Myotis nigricans and Lasiurus blossevillii, accounted for 19.9% of the captures. The native area presented higher values of species richness (S = 14) and diversity (H' = 1.4802) in comparison to the reforested area (S = 6, H '= 0.57015). The t-test evidenced a significant difference between diversity among the sites (t = 7.1075). Chao 1 index indicated that the sampling effort recorded approximately 78% from the total species richness for the native area and 75% for the reforested area. Therefore, the preservation of the forest fragment is essential since it provides habitat for a diverse community of bats. Forest management and reforestation

    One of the main problems related to air pollution in urban areas is caused by photochemical oxidants, particularly troposphere ozone (O3), which is considered a harmful substance. The O3 precursors (carbon monoxide CO, nitrogen oxides NOx and hydrocarbons HCs) are predominantly of anthropogenic origin in these areas, and vehicles are the main emission sources. Due to the increased urbanization and industrial development in recent decades, air pollutant emissions have increased likewise, mainly by mobile sources in the highly urbanized and developed areas, such as the Metropolitan Area of Porto Alegre-RS (MAPA). According to legal regulations implemented in Brazil in 2005, which aimed at increasing the fraction of biofuels in the national energy matrix, 2% biodiesel were supposed to be added to the fuel mixture within three years, and up to 5% after eight years of implementation of these regulations. Our work performs an analysis of surface concentrations for O3, NOx, CO, and HCs through numerical simulations with WRF/Chem (Weather Research and Forecasting model with Chemistry). The model is validated against observational data obtained from the local urban air quality network for the period from January 5 to 9, 2009 (96 hours). One part of the study focused on the comparison of simulated meteorological variables, to observational data from two stations in MAPA. The results showed that the model simulates well the diurnal evolution of pressure and temperature at the surface, but is much less accurate for wind speed. Another part included the evaluation of model results of WRF/Chem for O3 versus observed data at air quality stations Esteio and Porto Alegre. Comparisons between simulated and observed O3 revealed that the model simulates well the evolution of the observed values, but on many occasions the model did not reproduce well the maximum and minimum concentrations. Finally, a preliminary quantitative sensitivity study on the impact of biofuel on the

    In the present study, molecular detection of human adenoviruses (HAdV) and enteroviruses (EV) was performed in surface water samples collected from beaches Ipanema and Lami, located on the shores of Lake Guaíba, city of Porto Alegre, RS, southern Brazil. Furthermore, water safety was evaluated by counting thermotolerant coliforms (TC), following local government regulations. A total of 36 samples were collected monthly from six different sites along the beaches. Viral genomes were found in 30 (83.3%) samples. The higher detection rate was observed for HAdV (77.8%), followed by EV (22.2%). Although low concentrations of TC have been found, the occurrence of viral genomes in water samples was frequent and may pose a potential risk of infection for people bathing in these beaches.

    This study focuses on users' views of factors influencing quality of care at a health care unit in the city of Porto Alegre, relating to access and receptivity. The data were collected using a semi-structured interview and participatory observation and treated using thematic analysis. The results compare ease and difficulties in geographic, economic, and functional access. Organization of services and professional competency were determinant factors in ease of reception, leading to user satisfaction. Poor reception and unsatisfactory professional performance were identified as difficulties. The study concluded that there is a need to increase the professional staff, train them in receiving users, implement a complementary modality for dental care, open the facility earlier for scheduling appointments, and prioritize care for residents of the catchment area.

    The article analyzes the flow of penal sensitivities in relation to medical and health care provided to prisoners in Porto Alegre Prison between 1855 and 1888. The internalization and the instrumentalization of concepts such as "humanity" and "civilization," especially by those individuals involved directly or with strong chances of influencing changes pertaining to penal issues, are observed. Indeed, in addition to generating favorable public opinion, the concerns of governing authorities and leading lights led to the development of concrete measures and practices that increased the minimum subsistence offered to the imprisoned class. This process, however, was far from linear and harmonic as witnessed by the diseases and the precariousness of prison life. PMID:26331647

    The authors present a quantitative and qualitative study on homicides among teenagers in Porto Alegre, Rio Grande do Sul State, Brazil, based on a historical series during the 1990s and the life and death histories in this group, with a special focus on 1997. In that year there were 68 homicides in which the victims were from 10 to 19 years old. Of the 68, 62 were males and only 6 females, or a ratio of 10:1, showing that young males are more vulnerable and susceptible to being murdered. The data indicate that cause of death is influenced by gender culture and that homicides are based on power and status symbols characterizing a kind of virility. This expression of virility in the shaping of violence also appears in the domination of the female body observed in homicides with young women as the victims. The life and death histories of these teenagers highlight the pertinence of the gender-based analysis as a theoretical-analytical category, in addition to analyses considering socioeconomic aspects and social inequity.

    OBJECTIVE: To describe the prevalence of multidrug-resistant tuberculosis (MDR-TB) among tuberculosis patients in a major Brazilian city, evaluated via the Second National Survey on Antituberculosis Drug Resistance, as well as the social, demographic, and clinical characteristics of those patients. METHODS: Clinical samples were collected from tuberculosis patients seen between 2006 to 2007 at three hospitals and five primary health care clinics participating in the survey in the city of Porto Alegre, Brazil. The samples were subjected to drug susceptibility testing. The species of mycobacteria was confirmed using biochemical methods. RESULTS: Of the 299 patients included, 221 (73.9%) were men and 77 (27.3%) had a history of tuberculosis. The mean age was 36 years. Of the 252 patients who underwent HIV testing, 66 (26.2%) tested positive. The prevalence of MDR-TB in the sample as a whole was 4.7% (95% CI: 2.3-7.1), whereas it was 2.2% (95% CI: 0.3-4.2) among the new cases of tuberculosis and 12.0% (95% CI: 4.5-19.5) among the patients with a history of tuberculosis treatment. The multivariate analysis showed that a history of tuberculosis and a longer time to diagnosis were both associated with MDR-TB. CONCLUSIONS: If our results are corroborated by other studies conducted in Brazil, a history of tuberculosis treatment and a longer time to diagnosis could be used as predictors of MDR-TB.

    This is a retrospective study of 1,063 examinations performed on women at the Institute for Forensic Medicine in the city of Porto Alegre, RS, Brazil, between January 1998 and December 1999, as part of an investigation of charges of sexual abuse. Most women were white (83.9% - 892), single (89.1% - 947), and were between 11 and 20 years of age (59% - 627); 40% (425) were 14 years old or younger. There was evidence of previous sexual contact in 57% (606) of the patients; 37% (393) were virgins. Evidence of recent sexual intercourse was found in 287 (27%) cases, including presence of sperm in the vagina (18% - 191), recent rupture of the hymen (7% - 74), and pregnancy (2% - 21). Physical violence was evident in 30% (319) of all cases. In cases where information regarding the perpetrator was available (39% - 415), 25% (105) consisted of family members. Further studies should be carried out in order to assess the incidence of sexual violence by family members. PMID:15796005

    This article presents a study on the activities of the air traffic controllers of the Approach Control Area (APP) of Porto Alegre, Brazil, in different real scenarios. Based on interviews, questionnaires and the analysis of film of real scenes, the following were identified and analyzed: i) the perceptions of risk and complexity of the different air traffic scenes observed; ii) the cognitive factors (knowledge, strategy and attention dynamics) involved in the task and iii) the perception of the controller's workload. The results showed that the task complexity depends on the weather conditions, the number and type of aircraft in observation and that the controllers perceive the scenes in a similar way irrespective of their time in the profession and the type of control (radar or coordination). Attention is the cognitive factor with the greatest impact on the work and mental demand has the greatest impact on workload followed by time demand. The literature on the controllers work in Brazil is scarce and, therefore, this study aimed to contribute to the understanding of the work in one APP in order to promote future changes in the very problematic Brazilian air traffic system.

    The yeasts of the genus Candida infect skin, nails, and mucous membranes of the gastrointestinal and the genitourinary tract. The aim of this study was to determine the prevalence of dermatomycoses caused by Candida spp., and their etiological aspects in the metropolitan area of Porto Alegre, Brazil. A retrospective study with data obtained from tertiary hospital patients, from 1996 to 2011, was performed. The analyzed parameters were date, age, gender, ethnicity, anatomical region of lesions, and the direct examination results. For all the statistical analyses, a = 0.05 was considered. Among positive results in the direct mycological examination, 12.5% of the total of 4,815 cases were positive for Candida spp. The angular coefficient (B) was -0.7%/ year, showing a decrease over the years. The genus Candida was more prevalent in women (15.9% of women versus 5.84% of men), and in addition, women were older than men (54 versus 47 years old, respectively). There was no difference between ethnic groups. The nails were more affected than the skin, with 80.37% of the infections in the nails (72.9% in fingernails and 7.47% in toenails). Our study corroborates the literature regarding the preference for gender, age, and place of injury. Moreover, we found a decrease in infection over the studied period. PMID:27007557

All the food served in the meal of the session visited was analyzed for Escherichia coli, coagulase-positive Staphylococcus, Salmonella sp. and Shigella sp. Of the total of 196 food products analyzed in 120 schools, 4 contained and Escherichia coli score above the permitted level, and 2 contained coagulase-positive Staphylococcus. Neither Shigella nor Salmonella genus were detected. In the majority of schools studied, it was found that food was of an adequate hygienic-sanitary standard. However, only municipal schools had the supervision of a technician responsible for school food. In the state schools, 60% had never been visited by a nutritionist and in these schools several procedures failed to comply with legal requirements. In most of the schools studied, the food served to students was within adequate standards, though the problems detected revealed the need for the implementation of Best Practices in the school environment.

    The structural framework and tectonic evolution of the sedimentary basins along the eastern margin of the South American continent are closely associated with the tectonic framework and crustal heterogeneities inherited from the Precambrian basement. However, the role of NW-SE and NNW-SSE structures observed at the outcropping basement in Southeastern Brazil and its impact over the development of those basins have not been closely investigated. In the continental region adjacent to the Campos Basin, we described a geological feature with NNW-SSE orientation, named in this paper as the Alegre Fracture Zone (AFZ), which is observed in the onshore basement and can be projected to the offshore basin. The main goal of this work was to study this structural lineament and its influence on the tectonic evolution of the central portion of the Campos Basin and adjacent mainland. The onshore area was investigated through remote sensing data joint with field observations, and the offshore area was studied through the interpretation of 2-D seismic data calibrated by geophysical well logs. We concluded that the AFZ occurs in both onshore and offshore as a brittle deformation zone formed by multiple sets of fractures that originated in the Cambrian and were reactivated mainly as normal faults during the rift phase and in the Cenozoic. In the Campos Basin, the AFZ delimitates the western side of the Corvina-Parati Low, composing a complex fault system with the NE-SW faults and the NW-SE transfer faults.

    This descriptive transversal epidemiological study had the objective of comparing the elderly population who took the influenza vaccine and who did not regarding the occurrence of events of diseases or hospital admittances within three months after the vaccination. It was not possible to work with probable sampling and the attempt of pairing the vaccinated and non-vaccinated elderly was not successful due to the high vaccine coverage observed (73% of the target population) and due to the short time available to make the interviews. The result of the descriptive analysis of the 1,130 elderly interviewed was quite interesting even not being possible to infer it regarding the universe of the elderly population from Porto Alegre. We found a higher proportion of vaccinated people in the age group of 70 to 79 years old (42%), and a prevalence of non-vaccinated among the age group of 60 to 64 years old (40%). The vaccinated elderly were mostly older; female, who have private health care insurance; with higher income; that perform physical activities and non-smokers. The non-vaccinated were mostly men; younger; with lower income; that do not perform physical exercises; and smoke. A lower percentage of pneumonias reports and hospital admittances was observed among the vaccinated in comparison to the non-vaccinated people. PMID:20922296

    The scope of this paper is to analyze and compare the evolution of deaths from violent causes among adolescents and young adults in the cities of Cordoba (Argentina) and Porto Alegre (Brazil). It also seeks to establish if the results are consistent with those reported in previous national and local research. Based on official data, specific mortality rates (by sex, age and cause) are calculated for the 1990-92 and 2008-10 periods. In general, violent causes play a significant part in the total number of deaths especially among young men and as they get older. In line with the reality of the country, in Córdoba both non-traffic-related and also traffic-related deaths are most frequent. On the other hand, in Porto Alegre (where the level of deaths from violent causes is higher), homicides and traffic accidents are the most common cause of death. Beyond the actions taken so far, it is necessary to redouble efforts to counter the problem in question, both in the recording of information for decision-making and in regard to the decisions when they are put into practice.

    This study aims to characterize the scolecodonts, trilobite pygidium fragments and fish remains of an outcropped region in the southern Amazonas Basin, comprising the uppermost section of the Monte Alegre Formation and the basal section of the Itaituba Formation. These, correspond to part of the marine portion of the Tapajós Group, related to an intracratonic carbonate platform. The Monte Alegre Formation includes a deposition of fluvial-deltaic and aeolian sandstones, siltstones and shales of interdunes and lakes, intercalated with transgressive carbonates of a shallow restrict nearshore marine environment. The Itaituba Formation comprises a thickest deposit of marine carbonates, representing the establishment of widespread marine conditions, and is the richest interval containing organisms of shallow marine environment in the Pennsylvanian of the Amazonas Basin. The associated fauna includes brachiopods, bivalves, gastropods, crinoids, echinoids, bryozoans, corals, foraminifers, sponges, ostracods, trilobites, scolecodonts, fish remains and conodonts, mainly in the packstones, and subordinately in the wackestones and mudstones. Conodonts Neognathodus atokaensis, Diplognathodus orphanus, Idiognathodus incurvus, and foraminifers Millerella extensa, Millerella pressa, Millerella marblensis, Eostaffella ampla, Eostaffella pinguis and Eostaffella advena characterizes a predominant Atokan age to the analyzed profile. The fossil association herein presented is taxonomically diversified and biologically interesting, comprising an important and well preserved, for the first time occurrence of two molds and two fragments of Proetida trilobites. Well preserved Eunicida and Phyllodocida scolecodonts and paleonisciform fish remains. These fossils help in the paleoenvironmental establishment of the studied interval in the Amazonas Basin and as a potential biostratigraphic and paleoecological tool to correlate regionally and globally the Pennsylvanian.

    This article aims to determine the pattern of alcohol use in the elderly and its associations with sociodemographic characteristics in an elderly sample of patients from the city of Porto Alegre, Rio Grande do Sul, Brazil. A cross-sectional study was conducted involving 557 seniors, aged 60 years or more, through application of the Mini International Neuropsychiatric Interview and a global assessment questionnaire for the elderly. The majority of the 557 senior citizens did not complete elementary school (58.3%), were white (65.1%), married (37.6%), had no caregiver (62.2%), were catholic (65.5%) and practicing their religion (68.6%), were retired (67.7%), and had a personal income of up to one minimum salary (56.1%). The study revealed 67 (12%) elderly people with a history of alcoholism, of which 17 (3.1%) had a diagnosis of current alcoholism, 50 (9%) had a history of alcohol dependence in the past and 16 (2.9%) had a current alcohol abuse problem. Men had a prevalence ratio of 11.6 times for a history of alcoholism in comparison to women. The results confirm that alcoholism is frequent in the population of Brazilian elderly, drawing attention to some socio-demographic characteristics that can make a difference in the early diagnosis of alcoholism.

    The purpose of the present study was to evaluate the polycyclic aromatic hydrocarbons (PAHs) in fine (PM2.5) and coarse particles (PM2.5-10) in an urban and industrial area in the Metropolitan Area of Porto Alegre (MAPA), Brazil. Sixteen U.S. Environmental Protection Agency (EPA) priority polycyclic aromatic hydrocarbons (PAHs) were measured. Filters containing ambient air particulate were extracted with dichloromethane using Soxhlet. Extracts were later analyzed, for determining PAH concentrations, using a gaseous chromatograph coupled with a mass spectrometer (GC-MS). The polycyclic aromatic hydrocarbons (PAHs) were more concentrated in PM2.5 with an average of 70% of total PAHs in the MAPA. The target PAH apportionment among the main emission sources was carried out by diagnostic PAH concentration ratios, and principal component analysis (PCA). PAHs with higher molecular weight showed higher percentages in the fine particles in the MAPA. Based on the diagnostic ratios and PCA analysis, it may be concluded that the major contribution of PAHs was from vehicular sources (diesel and gasoline), especially in the PM2.5 fraction, as well as coal and wood burning. The winter/summer ratio in the PM2.5 and PM2.5-10 fractions in the MAPA was 3.1 and 1.8, respectively, revealing the seasonal variation of PAHs in the two fractions. The estimated toxicity equivalent factor (TEF), used to assess the contribution of the carcinogenic potency, confirms a significant presence of the moderately active carcinogenic PAHs BaP and DahA in the samples collected in the MAPA.

    Purpose To evaluate the clinical features and treatment outcomes of patients with pulmonary tuberculosis, stratified by level of drug resistance. Methods This was a historical cohort study based on data from the II National Anti-Tuberculosis Drug Resistance Survey (2006–2007) collected at eight participating health care facilities in Porto Alegre, southern Brazil. The cohort was followed for 3 years after the start of treatment. Results Of 299 cases of smear-positive pulmonary tuberculosis included in the study, 216 (72.2%) were diagnosed at five public primary health care units and 83 (27.8%) at three public hospitals. Among these cases, the prevalence of drug-resistant tuberculosis was 14.4%, and that of multidrug-resistant tuberculosis was 4.7%. Overall, 32.0% of drug-resistant and 2.0% of multidrug-resistant cases occurred in previously treated patients. The most common comorbidity in the sample was HIV infection (26.2%). There was no association between drug-resistant or multidrug-resistant tuberculosis and sociodemographic variables. Cure was achieved in 66.7% of patients, and the default rate was 21.2%. The 2-month sputum conversion rate was 34.2%, and the relapse rate was 16.9%. Patients with drug-resistant tuberculosis had lower rates of cure (45.2%) and 2-month sputum conversion (25%), as well as a higher relapse rate (30.7%). Conclusion These results highlight the urgent need for a more effective TB control program in this geographical setting, with a major emphasis on treatment of drug-resistant and multidrug-resistant tuberculosis.

    We describe the outlines of a project for the interconnection between the Astrophysical Station of Bosque Alegre and the wide area network of the University of Córdoba. The Astrophysical Station is located 38.55 km (23.96 milles) from the Observatory of Córdoba. This location is suitable for radio links in the range of centimeters wavelenghts. In the last years, Spread-Spectrum technology equipments has become popular. Spread-Spectrum signals, contrary to narrow band radio signals, operates within a widthband 20 to 200 times broader than the widthband of the modulated information. Signals are modulated by special spreading codes, in such a way that emulates noisy signals. These codes are known under the generic designation of pseudo-random or pseudo-noise. In addition, the wide band is correlated with a low power density in the emitted signals. Spread-Spectrum equipment links are stable, exhibits low interferences with conventional radio transmitters, and their commercial prices are remarkably lower than those for the conventional microwave devices. Data links are compliant with Ethernet protocol networks and operates with data tramsmition rates up to 4 Mbits per second. The described equipment will enable the access to full-Internet services for visitor astronomers in Bosque Alegre. Also, it will be possible fast transfer for the observational data from telescope to computers in the local area network at Córdoba. This project must be considered as the second stage of another wide purpose project, which has the main purpose in transforming the Bosque Alegre Station as a fully robotic station controlled from the computational center at the Observatory in Cordoba. The advantages of robotic telescopes has recently been the subject of several discussions. However, it is now widely accepted that an automatic station enables some important options in the use of the astronomical instruments, such us the possibility of performing parallel programs, one of which is

    Background Breast cancer (BC) is a major public health problem, with rising incidence in many regions of the globe. Although mortality has recently dropped in developed countries, death rates are still increasing in some developing countries, as seen in Brazil. Among the reasons for this phenomenon are the lack of structured screening programs, a long waiting period between diagnosis and treatment, and lack of access to health services for a large proportion of the Brazilian population. Methods and design Since 2004, an intervention study in a cohort of women in Southern Brazil, denominated Porto Alegre Breast Health Intervention Cohort, is being conducted in order to test the effectiveness and cost-effectiveness of a model for BC early detection and treatment. In this study, over 4,000 women from underserved communities aged 40 to 69 years are being screened annually with mammography and clinical breast examination performed by a multidisciplinary team, which also involves nutritional counseling and genetic cancer risk assessment. Risk factors for BC development are also being evaluated. Active search of participants by lay community health workers is one of the major features of our program. The accrual of new participants was concluded in 2006 and the study will last for 10 years. The main goal of the study is to demonstrate significant downstaging of BC in an underserved population through proper screening, attaining a higher rate of early-stage BC diagnoses than usually seen in women diagnosed in the Brazilian Public Health System. Preliminary results show a very high BC incidence in this population (117 cases per 100,000 women per year), despite a low prevalence of classical risk factors. Discussion This study will allow us to test a model of BC early diagnosis and treatment and evaluate its cost-effectiveness in a developing country where the mortality associated with this disease is very high. Also, it might contribute to the evaluation of risk factors in a

    Sesko, S C

    The author has been investigating the affective and intellectual views that gifted children have about computers. These studies have used various methodological approaches in order to develop a broad perspective on the issues involved in this topic. The author has used survey instruments (Sesko, 1998) and interview techniques (Sesko, 1999) to capture both statistical and narrative data. The objective of this study is to explore in depth the interactions that one student has with the machine and its applications. The driver for this and the previous studies was the paucity of research in the area of gifted and talented children and their involvement with what has become the primary intellectual tool of the century (Turkel, 1984). The second reason is that it has been posited that the intellectual characteristics of gifted children should enable those who are interested in computers to achieve a high level of proficiency with either computer applications or programming. Further, the ability to learn things at a young age should allow gifted children who use computers to develop a large variety of computer-based activities. The author has shown evidence to support these ideas in previous work. Finally, as Hausman (1985) claims, facilities with computers should allow these children to create new activities for using computers. The author found no published research to demonstrate whether they do; but still believes the results of this case study strongly support Hausman's contentions.

    Summary Introduction: Dance teachers are exposed to high sound intensities. Aim: To verify the sound intensity of music used by dance teachers during classes. Method: This was a transversal and prospective study. Dance teachers were evaluated with a sociodemographic questionnaire, and sound intensity level measurements were taken at the beginning, middle, and end of dance classes. Results: The sample comprised 35 teachers (average age, 31.8 years). The duration of their career as dance teachers was 1–37 years; they worked daily for approximately 1–10 h. Among the classes followed, there were 15 (42.85%) classical ballet classes, 4 (11.42%) tap dancing lessons, 5 (14.28%) jazz dance classes, 2 (5.71) Arab dance lessons, 6 (17.14%) street dance classes, and 3 (8.57%) ballroom dancing lessons. The average values observed at the beginning, middle, and end of the classes were 80.91 dB (A), 83.22 dB (A), and 85.19 dB (A), respectively. The music played in the street dance classes exposed teachers to the highest sound intensity. Conclusion: The average level of sound intensity of the dance classes in this study was either below or equal to the limit considered harmful for hearing health. Analysis of different class types showed that the sound densities of street, ballroom, and tap dance classes were above the recommended limits. PMID:25991989

    Two visions of the nosocomial architecture are discussed, located in a close time period, 1505-1535, but inserted in two different scenarios. One is in the Renaissance Spain, proposed by the architect E. Egas (born in Toledo, Spain), and the other one in the New Spain, proposed by V. de Quiroga, who chose an architectural style coherent with the Franciscan ideals of humbleness and evangelization, which set aside the ornamentation typical of Spanish medieval hospitals rather than palatial monuments built by E. Egas. The "hospital-village" project by V. de Quiroga allowed the patients and their families to live together, which was accepted by pre-Hispanic families that in the time were extensive. The hospital-village, both in its typology and in its health conception, returns to designs already in disuse of the Spanish Middle Age by picking up the idea of a hospital as a multifunctional space in which sanitary attention, nurseries, and shelters for poor people were combined within the church.

    Disturbing data reveal the prevalence of intestinal parasites and their relationship with socio-environmental factors among Mbyá-Guarani Indians. The prevalence was determined by spontaneous sedimentation in water, centrifugation-floatation, and Kato-Katz. A socioeconomic questionnaire was submitted to each family. The overall prevalence of intestinal parasites was 88.7%, and 45.5% were polyparasitized. There was 90.5% prevalence of enteric parasites in children (1-12- year-old), and 85% among 13-65-year-old individuals, indicating that both age groups are extensively parasitized. The parasite load was low to moderate for geohelminths and 75% of the families did not have latrine, thus the practice of defecation occurred outdoors. These findings suggest that the multiple intestinal parasitism in the Mbyá-Guarani community is high to the point of being the rule, and that it relates essentially to the traditional lifestyle and health habits. It is urgently necessary to implement the association of anti-parasitic treatment with sanitation improvement. This should be done simultaneously with health education activities for this population.

    Recently kidney transplantation has become an accepted treatment modality for the treatment of HIV infected patients with end-stage renal diseases. For such treatment it is required stability of clinical and laboratory parameters related to HIV infection and the use of highly active antiretroviral therapy. In this report we present the first two cases in Brazil of patients with HIV infection transplanted with organs from deceased donors performed successfully in our institution. The interactions between immunosuppressive and antiretroviral drugs, the co-infections, cardiovascular risk profile and the high incidence of acute rejection remain the major problems to be dealt with in these patients.

    BACKGROUND: Cutaneous melanoma dermal invasion, identified through measurement of maximum tumour thickness and sentinel lymph node (SLN) biopsy, is important to establish melanoma prognosis and progression. P16 protein expression has been shown to be a predictive factor for melanoma evolution and prognosis. OBJECTIVE: To investigate p16 protein expression in cutaneous melanomas with and without SLN metastasis. PATIENTS AND METHODS: Sixty-seven paraffin-embedded cutaneous melanoma specimens of patients who had undergone SLN investigation were evaluated from 1995 to 2007. SLN biopsy was negative for metastasis in 34 of these patients (controls); in the remaining 33 patients, SLN biopsy was positive (cases). The expression of p16 protein in the primary tumour was measured using an immunohistochemical assay. The samples were classified according to their nuclear expression. RESULTS: P16 nuclear expression was absent in 14 cases and in 15 controls; P=0.812. There was no statistically significant difference in p16 nuclear expression between cases and controls. CONCLUSIONS: The present study does not support the findings of other studies that suggest p16 protein expression is important in the prognosis of cutaneous melanoma. PMID:22942654

    The Casa Fonte Colombo (CFC) is a religious organisation that assists people living with HIV/AIDS (PLWHA). The funding for its activities comes from public sources such as the Brazilian National STD/AIDS Program as well as the Catholic Church. Capuchin (Franciscan) priests run the CFC, and it has an extensive group of volunteers made up mostly of women. Between 2006 and 2009, we observed daily life at the Casa Fonte Colombo and interviewed priests, volunteers, employees, service providers, and clients. We also attended meetings, group sessions, and celebrations. Everyday actions carried out by the CFC reveal the efforts to resolve the tension between the position of the Catholic Church and the Brazilian state in the politics of AIDS. These efforts affirm that the Casa Fonte Colombo presents itself as a space where the position of the Catholic Church, as much as the politics of public health, are re-worked, giving way to a progressive act of Catholic prevention and assistance for AIDS, that we call “theology of prevention.” PMID:21834734

    Kinase inhibition is considered to be an important therapeutic target for LRRK2 mediated Parkinson's disease (PD). Many LRRK2 kinase inhibitors have been reported but have yet to be optimized in order to qualify as drug candidates for the treatment of the disease. In order to start a structure-function analysis of such inhibitors, we mutated the active site of Dictyostelium Roco4 kinase to resemble LRRK2. Here, we show saturation transfer difference (STD) NMR and the first cocrystal structures of two potent in vitro inhibitors, LRRK2-IN-1 and compound 19, with mutated Roco4. Our data demonstrate that this system can serve as an excellent tool for the structural characterization and optimization of LRRK2 inhibitors using X-ray crystallography and NMR spectroscopy.

    Ras of complex proteins (Roc) is a Ras-like GTP-binding domain that always occurs in tandem with the C-terminal of Roc (COR) domain and is found in bacteria, plants and animals. Recently, it has been shown that Roco proteins belong to the family of G-proteins activated by nucleotide (nt)-dependent dimerization (GADs). We investigated the RocCOR tandem from the bacteria Chlorobium tepidum with site-directed spin labelling and pulse EPR distance measurements to follow conformational changes during the Roco G-protein cycle. Our results confirm that the COR domains are a stable dimerization device serving as a scaffold for the Roc domains that, in contrast, are structurally heterogeneous and dynamic entities. Contrary to other GAD proteins, we observed only minor structural alterations upon binding and hydrolysis of GTP, indicating significant mechanistic variations within this protein class. Mutations in the most prominent member of the Roco family of proteins, leucine-rich repeat (LRR) kinase 2 (LRRK2), are the most frequent cause of late-onset Parkinson's disease (PD). Using a stable recombinant LRRK2 Roc-COR-kinase fragment we obtained detailed kinetic data for the G-protein cycle. Our data confirmed that dimerization is essential for efficient GTP hydrolysis and PD mutations in the Roc domain result in decreased GTPase activity. Previous data have shown that these LRRK2 PD-mutations are located in the interface between Roc and COR. Importantly, analogous mutations in the conserved C. tepidum Roc/COR interface significantly influence the structure and nt-induced conformational changes of the Roc domains. PMID:26310572

  7. Highly Dynamic Exon Shuffling in Candidate Pathogen Receptors … What if Brown Algae Were Capable of Adaptive Immunity?

    Zambounis, Antonios; Elias, Marek; Sterck, Lieven; Maumus, Florian; Gachon, Claire M.M.

    2012-01-01

    Pathogen recognition is the first step of immune reactions. In animals and plants, direct or indirect pathogen recognition is often mediated by a wealth of fast-evolving receptors, many of which contain ligand-binding and signal transduction domains, such as leucine-rich or tetratricopeptide repeat (LRR/TPR) and NB-ARC domains, respectively. In order to identify candidates potentially involved in algal defense, we mined the genome of the brown alga Ectocarpus siliculosus for homologues of these genes and assessed the evolutionary pressures acting upon them. We thus annotated all Ectocarpus LRR-containing genes, in particular an original group of LRR-containing GTPases of the ROCO family, and 24 NB-ARC–TPR proteins. They exhibit high birth and death rates, while a diversifying selection is acting on their LRR (respectively TPR) domain, probably affecting the ligand-binding specificities. Remarkably, each repeat is encoded by an exon, and the intense exon shuffling underpins the variability of LRR and TPR domains. We conclude that the Ectocarpus ROCO and NB-ARC–TPR families are excellent candidates for being involved in recognition/transduction events linked to immunity. We further hypothesize that brown algae may generate their immune repertoire via controlled somatic recombination, so far only known from the vertebrate adaptive immune systems. PMID:22144640

  8. Effect of Li 2CO 3 additive on gas generation in lithium-ion batteries

    NASA Astrophysics Data System (ADS)

    Shin, Jee-Sun; Han, Chi-Hwan; Jung, Un-Ho; Lee, Shung-Ik; Kim, Hyeong-Jin; Kim, Keon

    To elucidate the mechanism of gas generation during charge-discharge cycling of a lithium-ion cell, the generated gases and passive films on the carbon electrode are examined by means of gas chromatography (GC) and Fourier transform infrared (FTIR) spectroscopy. In ethyl carbonate/dimethyl carbonate and ethyl carbonate/diethyl carbonate 1 M LiPF 6 electrolytes, the detected gaseous products are CO 2, CO, CH 4, C 2H 4, C 2H 6, etc. The FTIR spectrum of the surface of the carbon electrode shows bands which correspond to Li 2CO 3, ROCO 2Li, (ROCO 2Li) 2, and RCO 2Li. These results suggest that gas evolution is caused by electrode decomposition, reactive trace impurities, and electrolyte reduction. The surface of the electrode is composed of electrolyte reduction products. When 0.05 M Li 2CO 3 is added as an electrolyte additive, the total volume of generated gases is reduced, and the discharge capacity and the conductivity of lithium-ions are increased. These results can be explained by a more compact and thin 'solid electrolyte interface' film on the carbon electrode formed by Li 2CO 3, which effectively prevents solvent co-intercalation and carbon exfoliation.

  9. Activation Mechanism of LRRK2 and Its Cellular Functions in Parkinson's Disease

    PubMed Central

    Rosenbusch, Katharina E.; Kortholt, Arjan

    2016-01-01

    Human LRRK2 (Leucine-Rich Repeat Kinase 2) has been associated with both familial and idiopathic Parkinson's disease (PD). Although several LRRK2 mediated pathways and interaction partners have been identified, the cellular functions of LRRK2 and LRRK2 mediated progression of PD are still only partially understood. LRRK2 belongs to the group of Roco proteins which are characterized by the presence of a Ras-like G-domain (Roc), a C-terminal of Roc domain (COR), a kinase, and several protein-protein interaction domains. Roco proteins exhibit a complex activation mechanism involving intramolecular signaling, dimerization, and substrate/effector binding. Importantly, PD mutations in LRRK2 have been linked to a decreased GTPase and impaired kinase activity, thus providing putative therapeutic targets. To fully explore these potential targets it will be crucial to understand the function and identify the pathways responsible for LRRK2-linked PD. Here, we review the recent progress in elucidating the complex LRRK2 activation mechanism, describe the accumulating evidence that link LRRK2-mediated PD to mitochondrial dysfunction and aberrant autophagy, and discuss possible ways for therapeutically targeting LRRK2.

  15. Lithium compound deposition on mesocarbon microbead anode of lithium ion batteries after long-term cycling.

    Lithium compound deposition on mesocarbon microbead (MCMB) anode after long-term cycling was studied in LiCoO2/MCMB battery. Lithium compound deposition did not generate on the activated MCMB anode, but it generated unevenly on the long-term cycled anode. Gray deposition composed of dendrites and particles was formed on the lower surface of the MCMB layer first, then on the upper surface. The deposition and MCMB layer peeled off from the current collector, and a bump was formed in the cycled anode. The exfoliation and thick deposition increased the ohmic resistance, film resistance, and charge transfer resistance of the cell and decreased the capacity significantly. Metallic lithium did not exist in either the upper or the lower deposition layer according to the results of X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), the discharge curve, and anode potential. The outer region of both the lower and the upper deposition layers consisted of Li2CO3, LiOH, ROCO2Li, and ROLi. The inner region of the etched lower deposition layer mainly consisted of Li2O, LiF, and Li2CO3, and that of the etched upper deposition layer mainly consisted of Li2CO3, ROCO2Li, ROLi, and LiF. Solid electrolyte interphase (SEI) film hindering the intercalation of lithium ions into carbon layers and LiCoO2 cathode providing lithium source for the deposition were the two reasons leading to the formation of lithium compound deposition during long-term cycles. Because SEI film on the lower surface of MCMB layer was thicker than that on the upper surface, lithium compound deposition generated on the lower surface first. PMID:25020035

    OBJECTIVE To assess the feasibility of HIV rapid testing for pregnant women at maternity hospital admission and of subsequent interventions to reduce perinatal HIV transmission. METHODS Study based on a convenience sample of women unaware of their HIV serostatus when they were admitted to delivery in public maternity hospitals in Rio de Janeiro and Porto Alegre, Brazil, between March 2000 and April 2002. Women were counseled and tested using the Determine HIV1/2 Rapid Test. HIV infection was confirmed using the Brazilian algorithm for HIV infection diagnosis. In utero transmission of HIV was determined using HIVDNA-PCR. There were performed descriptive analyses of sociodemographic data, number of previous pregnancies and abortions, number of prenatal care visits, timing of HIV testing, HIV rapid test result, neonatal and mother-to-child transmission interventions, by city studied. RESULTS HIV prevalence in women was 6.5% (N=1,439) in Porto Alegre and 1.3% (N=3.778) in Rio de Janeiro. In Porto Alegre most of women were tested during labor (88.7%), while in Rio de Janeiro most were tested in the postpartum (67.5%). One hundred and forty-four infants were born to 143 HIV-infected women. All newborns but one in each city received at least prophylaxis with oral zidovudine. It was possible to completely avoid newborn exposure to breast milk in 96.8% and 51.1% of the cases in Porto Alegre and Rio de Janeiro, respectively. Injectable intravenous zidovudine was administered during labor to 68.8% and 27.7% newborns in Porto Alegre and Rio de Janeiro, respectively. Among those from whom blood samples were collected within 48 hours of birth, in utero transmission of HIV was confirmed in 4 cases in Rio de Janeiro (4/47) and 6 cases in Porto Alegre (6/79). CONCLUSIONS The strategy proved feasible in maternity hospitals in Rio de Janeiro and Porto Alegre. Efforts must be taken to maximize HIV testing during labor. There is a need of strong social support to provide this

    2015-01-01

    The latest studies on epistemological thought of Gaston Bachelard, especially in France and Italy, they are highlighting some fundamental issues, such as creative and propulsive assigned to mathematics in the construction of physical reality. The studies of Bachelard on the quantum mechanics of the '30s, and especially on the theoretical physics of Paul Dirac, introduced a particular concept of "anagogical reverie" precisely in order to understand the increasingly abstract and creative thinking of mathematics in the various levels of physical reality. In the wake of what Federigo Enriques called "mathematical poetry", Bachelard comes to propose a real "nouménologie mathématique" which characterizes the contemporary scientific thought and which provides the basis epistemic appropriate to understand the 'rational effectiveness' of mathematics and the real meaning of their application to the real. For these reasons, Bachelard in the '30s used a new term to describe his rationalist engagement, the "surrationalisme", just to understand in depth what Enriques called the "implicit philosophy" in sciences, the "pensée des sciences", where mathematics, thanks to the "anagogical reverie", put in place continue "enjeux" of the rational.

Benthic O2 fluxes were used to calculate net community production using both the boundary layer gradient and enclosure techniques. The boundary layer O2 gradient and the drag coefficients were used to calculate productivity ranging from -12.3 to 13.7 mmol O2 m-2 h-1. Productivity measurements from the enclosure method ranged from -11.0 to 12.9 mmol O2 m-2 h-1. During the study, the mean hourly difference between the methods was 0.65 mmol O2 m-2 h-1 (r2 = 0.92), resulting in well-reconciled estimates of net community production between the boundary layer (-33.1 mmol m-2 d-1) and enclosure (-46.3 mmol m-2 d-1) techniques. The results of these independent approaches corroborate quantified rates of metabolism at Cayo Enrique Reef. Close agreement between methods demonstrates that boundary layer measurements can provide near real-time assessments of coral reef health.

    The leucine-rich repeat kinase (LRRK)-2 protein contains nonoverlapping GTPase and kinase domains, and mutation in either domain can cause Parkinson disease. GTPase proteins are critical upstream modulators of many effector protein kinases. In LRRK2, this paradigm may be reversed, as the kinase domain phosphorylates its own GTPase domain. In this study, we found that the ameba LRRK2 ortholog ROCO4 phosphorylates the GTPase domain [termed Ras-of-complex (ROC) domain in this family] of human LRRK2 on the same residues as the human LRRK2 kinase. Phosphorylation of ROC enhances its rate of GTP hydrolysis [from kcat (catalytic constant) 0.007 to 0.016 min(-1)], without affecting GTP or GDP dissociation kinetics [koff = 0.093 and 0.148 min(-1) for GTP and GDP, respectively). Phosphorylation also promotes the formation of ROC dimers, although GTPase activity appears to be equivalent between purified dimers and monomers. Modeling experiments show that phosphorylation induces conformational changes at the critical p-loop structure. Finally, ROC appears to be one of many GTPases phosphorylated in p-loop residues, as revealed by alignment of LRRK2 autophosphorylation sites with GTPases annotated in the phosphoproteome database. These results provide an example of a novel mechanism for kinase-mediated control of GTPase activity. PMID:26396237

    The solid electrolyte interphase (SEI) of the high capacity anode material Si is monitored over multiple electrochemical cycles by (7)Li, (19)F, and (13)C solid-state nuclear magnetic resonance spectroscopies, with the organics dominating the SEI. Homonuclear correlation experiments are used to identify the organic fragments -OCH2CH2O-, -OCH2CH2-, -OCH2CH3, and -CH2CH3 contained in both oligomeric species and lithium semicarbonates ROCO2Li, RCO2Li. The SEI growth is correlated with increasing electrode tortuosity by using focused ion beam and scanning electron microscopy. A two-stage model for lithiation capacity loss is developed: initially, the lithiation capacity steadily decreases, Li(+) is irreversibly consumed at a steady rate, and pronounced SEI growth is seen. Later, below 50% of the initial lithiation capacity, less Si is (de)lithiated resulting in less volume expansion and contraction; the rate of Li(+) being irreversibly consumed declines, and the Si SEI thickness stabilizes. The decreasing lithiation capacity is primarily attributed to kinetics, the increased electrode tortuousity severely limiting Li(+) ion diffusion through the bulk of the electrode. The resulting changes in the lithiation processes seen in the electrochemical capacity curves are ascribed to non-uniform lithiation, the reaction commencing near the separator/on the surface of the particles.

    The Jauru Terrain hosts the Figueira Branca Intrusive Suite (FBS) in the SW of the Amazon Craton (Brazil). The FBS is a series of 1425 Ma layered mafic intrusions, previously interpreted as anorogenic. The FBS area is located in foreland to the Santa Helena orogen, formed by the subduction of the Rio Alegre Terrain under the Jauru Terrain. Potential field methods (magnetic and gravity), gamma-ray spectrometry, geochemical and isotope data were used to characterize and to model the extent of FBS magmatism, the distribution of faults and shear zones in the area, to evaluate affinities of the magmatic activity, and the relation between the FBS and the Santa Helena orogen. The geophysical methods identified three anomalies corresponding with FBS outcrops. A fourth anomaly with significantly higher amplitude was observed to the north of the three anomalies. From south to north, the anomalies were named Indiavaí, Azteca, Figueira Branca and Jauru. These anomalies were modeled and indicated a northwest-southeast trend, parallel to regional shear zones. The gamma-ray data enabled the collection of 50 samples from the FBS rocks, the Alto Jauru group that hosts the FBS, from nearby intrusive suites, and the Rio Alegre Terrain. The 30 freshest samples were analyzed by X-ray fluorescence for oxides and some trace elements, 20 by ICP-MS for Rare-Earth Elements and 10 for Nd-Sr isotope analyses. The FBS samples were gabbros and gabbro-norites with Nb/Yb-Th/Yb and TiO2/Yb-Nb/Yb ratios indicating varying degrees of crustal interaction. The TiO2/Yb-Nb/Yb data suggested a subduction related component and the ɛNd-ɛSr indicated a juvenile source. Samples from coeval adjacent intermediate magma suites displayed similar characteristics, which suggest derivation from a bimodal source probably related with the subduction of the Rio Alegre Terrain. We interpreted the tectonic setting of the FBS as a result of a roll-back of the subducted slab, which resulted in rejuvenation of the

    This phenomenological study aimed at understanding, in the light of Martin Buber's philosophy, what is to be a caregiver of children with AIDS. The phenomenological interview guided the meeting with seven caregivers of children with AIDS, selected in a teaching hospital of Porto Alegre-RS, southern of Brazil. The data were interpreted in the light of hermeneutics, emerging the unit of meaning Dialogues 'between' the familiar I and the Eternal THOU. The dialogues take place in the search for answers that allow the understanding of the significance of the impact and challenges they face while living with AIDS. As well, they reveal hope in changes, in the cure and in a vaccine development. We believe that knowing the importance of dialogue in the context of HIV/AIDS epidemic provide the development of a nursing care that brings together the technical-scientific and humanistic aspects.

    OBJECTIVE: to propose a discussion about traces of the derivation of meanings, the subjects' discomfort and resistance when they are called upon to signify a questionnaire on the transfer of the Directly Observed Treatment of Tuberculosis policy, in order to reveal the limitations of closed questionnaires in the subject's interpretation process. METHOD: health professionals from a Primary Health Care Unit in Porto Alegre/RS were interviewed and some excerpts from the interviews were investigated in the light of French Discourse Analysis. RESULTS: resistance, discomfort, slips, silencing and the derivation of meanings were observed in the subjects' interpretation. CONCLUSION: the interpretation process has multiple meanings and varies from subject to subject. The questionnaire, as a prototype of the logically stabilized universe, fails when the purpose is to control the interpretation. Its isolated use in health research can entail inexactness or incompleteness of the collected data. Therefore, its use associated with qualitative research techniques is ideal. PMID:25591094

    The Family Health Strategy Service (FHSS) is an important ally in the mental health system, contributing to the completeness and effectiveness of care. This study aimed to discuss the mental health care network as compared to the daily routine of an FHSS. It is an evaluative study with a qualitative methodological approach. It was developed in an FHSS in Porto Alegre-RS, Brazil. Data was collected between July and December of 2010 through interviews with 16 workers and ten relatives. We identified important resources in primary health care, such as partnerships with academia. However, the constitution of this care is still based on specialty, following the logic of patient referral. Our intention for this study was to contribute to the operationalization of the mental health care network, consolidating the partnership with the FHSS and developing activities in the territorial space, raising awareness, demystifying health care service in the area, and countering the perception that it is uniquely specialized.

One such instance was represented by the Homeopathic League of Rio Grande do Sul, founded in 1941, which published a journal until the 1970s, set up three free dispensaries to serve the population in Porto Alegre, and played an active role in political discussions through a group of homeopaths who endeavored to disseminate and expand homeopathic practice. An analysis of the League's Boletim de Homeopatia provides insight into homeopaths' strategies for expanding their role in Porto Alegre, capital of Rio Grande do Sul. PMID:21779687

    Gamma rays with ~1 MeV energy are measured following the relativistic interaction of a 3 mJ, 1018 W/cm2 short pulse laser with a 30 μm diameter flowing water column. Contrary to expectations, radiation emission is peaked in the direction opposite to the normally-incident laser propagation (specular direction). Experimental measurements and particle-in-cell (PIC) simulations of laser-plasma interaction show a pre-formed-plasma-dependent, backward-going, beam-like primary electron source. The MeV component of the electron and gamma ray spectrum, which is more than five times the ponderomotive energy scale of the laser, is highly sensitive to the presence of a nanosecond-timescale laser pre-pulse.

It was created in 1987 by the present Dean, Aleksandar Goic. The present article describes one of the halls, the Colony. Pictures of Governors and Conquerors who founded the first hospitals are in display. The period of Religious Medicine (1616-1823) is represented by pictures and religious objects, as well as hospital utensils. The times of the University of San Felipe and the "Protomedicato" (1756-1839) includes pictures and documentation from the first colonial physicians. Chilean medicine at that time stayed at a medieval level, lacking the influence of the Renaissance, the Barroque and other movements enlighting european medicine. PMID:2519478

    X-ray photoelectron spectroscopy and scanning electron microscopy were used to study electrode samples obtained from 18650-type lithium-ion cells subjected to accelerated calendar-life testing at temperatures ranging from 25 to 70 C and at states-of-charge from 40 to 80%. The cells contained LiNi{sub 0.8}Co{sub 0.2}O{sub 2}-based positive electrodes (cathodes), graphite-based negative electrodes (anodes), and a 1 M LiPF{sub 6} ethylene carbonate:diethyl carbonate (1:1) electrolyte. The results from electrochemically treated samples showed surface film formation on both electrodes. The positive electrode laminate surfaces contained a mixture of organic species that included polycarbonates, and LiF, Li{sub x}PF{sub y}-type and Li{sub x}PF{sub y}O{sub z}-type compounds. The same surface compounds were observed regardless of test temperature, test duration, and state-of-charge. On the negative electrode laminates lithium alkyl carbonates (ROCO{sub 2}Li) and Li{sub 2}CO{sub 3} were found in addition to the above-mentioned compounds. Decomposition of lithium alkyl carbonates to Li{sub 2}CO{sub 3} occurred on negative electrodes stored at elevated temperature. Initial depth-profiling results suggest that the surface layer thickness is greater on positive electrode samples from cells stored at high temperature than on samples from cells stored at room temperature. This observation is significant because positive electrode impedance, and more specifically, charge-transfer resistance at the electrode/electrolyte interface, has been shown to be the main contributor to impedance rise in these cells.

    Mutations in the leucine-rich repeat kinase 2 (LRRK2) gene are the most prevalent known cause of autosomal dominant Parkinson's disease (PD). The LRRK2 gene encodes a Roco protein featuring a ROC GTPase and a kinase domain linked by the C-terminal of ROC (COR) domain. Here, we explored the effects of the Y1699C pathogenic LRRK2 mutation in the COR domain on GTPase activity and interactions within the catalytic core of LRRK2. We observed a decrease in GTPase activity for LRRK2 Y1699C comparable to the decrease observed for the R1441C pathogenic mutant and the T1348N dysfunctional mutant. To study the underlying mechanism, we explored the dimerization in the catalytic core of LRRK2. ROC-COR dimerization was significantly weakened by the Y1699C or R1441C/G mutation. Using a competition assay we demonstrated that the intra-molecular ROC:COR interaction is favoured over ROC:ROC dimerization. Interestingly, the intra-molecular ROC:COR interaction was strengthened by the Y1699C mutation. This is supported by a 3D homology model of the ROC-COR tandem of LRRK2, showing that Y1699 is positioned at the intra-molecular ROC:COR interface. In conclusion, our data provides mechanistic insight into the mode of action of the Y1699C LRRK2 mutant: the Y1699C substitution, situated at the intra-molecular ROC:COR interface, strengthens the intra-molecular ROC:COR interaction, thereby locally weakening the dimerization of LRRK2 at the ROC-COR tandem domain resulting in decreased GTPase activity.

    This study examined the social integration of intra-Caribbean migrants within lower socioeconomic strata in Trinidad, in 1994. Data were obtained from in-depth interviews among 22 migrants. Integration means labor market participation, social interaction, political and organizational activities, and cultural encounters. Findings are not generalizable to the larger immigrant population in Trinidad. The target population was recruited through church organizations and schools. Migrants came from Grenada, St. Vincent, and Guyana. All were first generation labor migrants to Trinidad. Most located well-established circles of their own native countrymen. There were 6 males and 16 females, of whom 5 were aged 20-34 years, 8 were aged 35-64 years, and 9 were elderly. 8 had lived in Trinidad for up to 20 years and 14 lived in Trinidad over 20 years. Migrants lived in Laventille/Morvant outside Port of Spain, and in Roco, a rural village in the northeast. 16 lived in rental housing. Although all lived in low income areas, the housing ranged from substandard to adequate and pleasant. Primary support groups were friends, neighbors, and kin. Some felt social competition from Trinidadians who did not like to see migrants advancing economically. Four of the working age migrants were homemakers. Five were underemployed. The unemployed viewed themselves as work seekers and were similar to unemployed Trinidadians. Some elderly qualified for state old-age pensions. Pensioners supplemented their pension with informal activity. Migrants supported political parties. Religion and church attendance were important. Integration softened the problems of life. Social adjustment and marketable skills were not being transferred between generations. Social integration with natives was facilitated by 7 factors, including ethnocultural affinity, which promotes a sense of belonging. PMID:12347794

    The recent discovery of the genetic causes for Parkinson's disease (PD) is fruitful; however, the continuing revelation of PD-related genes is rapidly outpacing the functional characterization of the gene products. Although the discovery of multiple PD-related genes places PD as one of the most complex multigenetic diseases of the brain, it will undoubtedly facilitate the unfolding of a central pathogenic pathway and an understanding of the etiology of PD. Recent findings of pathogenic mutations in leucine-rich repeat kinase 2 (LRRK2) (PARK8) that are linked to the most common familial forms and some sporadic forms of PD provide a unique opportunity to gain insight into the pathogenesis of PD. Despite rapid growth in biochemical, structural and in vitro cell culture studies of LRRK2, the in vivo characterizations of LRRK2 function generally fall short and are largely limited to invertebrates. The investigation of LRRK2 or homologs of LRRK2 in nonmammalian models provides important clues with respect to the cellular functions of LRRK2, but an elucidation of the physiology and pathophysiology of LRRK2 relevant to PD would still depend on mammalian models established by multiple genetic approaches, followed by rigorous examination of the models for pathological process. This minireview summarizes previous studies of genes for ROCO and LRRK2 homologs in slime mold, nematode worms and fruit flies. It also discusses the results obtained from available mouse models of LRRK2 that begin to provide information for understanding LRRK2-mediated pathogenesis in PD. PMID:19804414

    Results from narrow-band photoelectric photometry of comet Halley after its perihelion passage are presented. The mean atmospheric extinction coefficients determined at Bosque Alegre for six bands between 3600 and 5200 Å are consistent with those of the UBV and DD0 systems. The largest fluxes measured successively correspond to the molecules of C2 , CN, and C3 . The CN emission is typically 70% of the one C2, while the one of C3 is about 20% . The observations show that : (i) There is no detectable contribution of molecular ions CO+ during the period in consideration. (ii) Between March 15 and 22 of 1986 there is a decrease in the proportion of molecules of C2,CN,andC3, with respect to the presence of dust indicate by the continuum. Similar decreases, observed with a P = 6d.1 ± 0d.2, coincide with disconnection events detected from Bosque Alegre and other observatories. If they correspond to the frequency of passage of magnetic solar sectors by the comet, a solar "synodic" rotation Pc = 4P = 24d.4±0d.8, with respect to the comet, is deduced. This value is in excellent agreement with the mean value of the apparent solar rotation with respect to the comet.

The several morpho-structural elements can be differentiated, as for example: the dominant structural pattern of the acoustic basement, including extensional faulting and long-wavelength folding, crustal thickness changes, fracture zones location, distribution of volcanic centers, and development of wedges of seaward-dipping reflectors. Four broad distinct morpho-structural domains, separated by fracture zones and oceanic lineaments. Domain I is located south of the Porto Alegre Lineament; Domain II corresponds to the area between the Porto Alegre Lineament and the Rio Grande Fracture Zone; Domain III spans the area of the São Paulo Plateau; and Domain IV is located to the east of this plateau, towards the abyssal portions of the oceanic crust. These domains are defined by their distinct regional morphologic and structural characteristics. Sometimes these elements are well imaged in the seismic profiles, corroborated by gravity and magnetic anomalies, and eventually identified as prominent features at the sea bottom physiography. Using a multidisciplinary approach based on bathymetric maps, regional seismic interpretation, magnetic data analysis, and gravity models, this work attempts to characterize these elements in a descriptive and evolutionary view, identifying their role in the tectonic development of this portion of the South Atlantic.

    The aim of this study was to evaluate the cost-effectiveness of an organized breast cancer mammographic screening program implemented in Porto Alegre (Núcleo Mama Porto Alegre - NMPOA), Rio Grande do Sul State, Brazil. A Markov model was constructed to estimate the incremental cost-effectiveness ratio of NMPOA compared to current BC diagnosis and care in the Brazilian public health system, in a hypothetical cohort of women aged 40-69 years at risk of developing breast cancer. Model parameters were collected from NMPOA and the national literature. In the NMPOA strategy, effectiveness was modeled taking into account the actual observed screening adherence. Effectiveness was measured in quality-adjusted life years (QALYs). Incremental cost-effectiveness ratio in the base case was R$ 13,426 per QALY. This result was not sensitive to variation in the main model parameters in sensitivity analyses. Considering the threshold usually suggested as highly attractive in Brazil, breast cancer screening as performed in NMPOA is cost-effective in cities with high incidence of breast cancer.

    2014-01-01

    Background There is evidence for a genetic contribution to chronic periodontitis. In this study, we conducted a genome wide association study among 866 participants of the University of Pittsburgh Dental Registry and DNA Repository, whose periodontal diagnosis ranged from healthy (N = 767) to severe chronic periodontitis (N = 99). Methods Genotypingi of over half-million single nucleotide polymorphisms was determined. Analyses were done twice, first in the complete dataset of all ethnicities, and second including only samples defined as self-reported Whites. From the top 100 results, twenty single nucleotide polymorphisms had consistent results in both analyses (borderline p-values ranging from 1E-05 to 1E-6) and were selected to be tested in two independent datasets derived from 1,460 individuals from Porto Alegre, and 359 from Rio de Janeiro, Brazil. Meta-analyses of the Single nucleotide polymorphisms showing a trend for association in the independent dataset were performed. Results The rs1477403 marker located on 16q22.3 showed suggestive association in the discovery phase and in the Porto Alegre dataset (p = 0.05). The meta-analysis suggested the less common allele decreases the risk of chronic periodontitis. Conclusions Our data offer a clear hypothesis to be independently tested regarding the contribution of the 16q22.3 locus to chronic periodontitis. PMID:25008200

  11. Population prevalence of hereditary breast cancer phenotypes and implementation of a genetic cancer risk assessment program in southern Brazil

    PubMed Central

    2009-01-01

    In 2004, a population-based cohort (the Núcleo Mama Porto Alegre - NMPOA Cohort) was started in Porto Alegre, southern Brazil and within that cohort, a hereditary breast cancer study was initiated, aiming to determine the prevalence of hereditary breast cancer phenotypes and evaluate acceptance of a genetic cancer risk assessment (GCRA) program. Women from that cohort who reported a positive family history of cancer were referred to GCRA. Of the 9218 women enrolled, 1286 (13.9%) reported a family history of cancer. Of the 902 women who attended GCRA, 55 (8%) had an estimated lifetime risk of breast cancer ≥ 20% and 214 (23.7%) had pedigrees suggestive of a breast cancer predisposition syndrome; an unexpectedly high number of these fulfilled criteria for Li-Fraumeni-like syndrome (122 families, 66.7%). The overall prevalence of a hereditary breast cancer phenotype was 6.2% (95%CI: 5.67-6.65). These findings identified a problem of significant magnitude in the region and indicate that genetic cancer risk evaluation should be undertaken in a considerable proportion of the women from this community. The large proportion of women who attended GCRA (72.3%) indicates that the program was well-accepted by the community, regardless of the potential cultural, economic and social barriers.

  12. ENSO-triggered floods in South America

    ENSO-triggered floods altered completely the annual discharge of most watersheds of South America. Anomalous years as 1941, 1982-83 and 1997-98 signified enormous discharges of rivers draining toward the Pacific but also to the Atlantic Ocean. These floods affected large cities as Porto Alegre, Blumenau, Curitiba, Asunción, Santa Fe and Buenos Aires. Maximum discharge months are particular and easily distinguished at those watersheds located at the South American Arid Diagonal. At watersheds conditioned by precipitations delivered from the Atlantic or Pacific anticyclonic centers the ENSO-triggered floods are difficult to discern. The floods of 1941 affected 70,000 inhabitants in Porto Alegre. In 1983, Blumenau city was flooded during several days; and the Paraná River multiplied 15 times the width of its middle floodplain. The Colorado River in Northern Patagonia connected for the last time to the Desaguadero-Chadileuvú-Curacó system and therefore received saline water. ENSO years modify also the water balance of certain piedmont lakes of Southern Patagonia: the increases in snow accumulations cause high water levels with a lag of 13 months. The correlation between the maximum monthly discharges of 1982-83 and 1997-98 at different regions and watersheds indicates they can be forecasted for future floods triggered by same phenomena. South American rivers can be classified therefore into ENSO-affected, and ENSO-dominated, for those within the Arid Diagonal that are exclusively subject to high discharges during these years.

  13. The pedagogical and ethical legacy of a "successful" educational reform: The Citizen School Project

    2016-02-01

    The Citizen School Project (Escola Cidadã) was implemented from 1993 to 2004 in Porto Alegre, capital of the Brazilian state of Rio Grande do Sul. This article presents the conception behind the Citizen School Project, the basic mechanisms created to implement and evaluate its strengths and weaknesses, and some of its contradictions. After contextualising the educational reforms in Brazil during the 1980s and 1990s, the authors demonstrate how the Citizen School Project's emphasis on participation and democratisation was a radical departure from Brazil's traditional public education system. Next, they present the three main goals and structures of the Citizen School Project - democratisation of access to schools, democratisation of schools' administration, and democratisation of access to knowledge. They conclude by discussing some pedagogic, social and political dynamics which appear to be strong legacies of this pedagogical project. The authors also argue that the Citizen School Project has both improved the quality of education in Porto Alegre and is an important contribution to our collective thinking about the politics of "successful" educational policies.

  14. The reactivity of metallic lithium toward solvents of relevance to energy storage: A surface science approach

    NASA Astrophysics Data System (ADS)

    Rendek, Louis Joseph, Jr.

    The reactivity of symmetric and asymmetric alkyl linear carbonates of the type ROCO2R', where R and R' represent methyl or ethyl groups, propylene carbonate (PC), gamma-butyrolactone (gamma-BL), dioxolane (DIOX) and tetrahydrofuran (THF) toward metallic Li was studied by infrared reflection absorption (IRAS), X-ray photoelectron (XPS) and Auger electron (AES) spectroscopies in ultrahigh vacuum (UHV). An identification of the products of these reactions may provide much needed insight into the physicochemical properties of passive films formed on Li electrodes, which are believed to be primarily responsible for controlling the performance of rechargeable Li batteries. Comparison of the IRAS and C(1s) and O(1s) XPS spectra of clean Li surfaces exposed to dimethyl (DMC), diethyl (DEC) and ethylmethyl carbonates (EMC) with those obtained in very similar experiments involving judiciously selected alcohols provided unambiguous evidence that the products of such reactions are primarily Li alkoxides (ROLi and RgammaOLi). Spectral evidence was also found for the presence of Li ethyl carbonate for experiments involving DEC and EMC, as well as Li oxide as judged by the occurrence of an O(1s) XPS peak at 530 eV. In the case of PC the IRAS and XPS spectra of PC/Li was found to be identical to that obtained by exposing Li to 1,2-propanediol vapors under otherwise identical conditions, and may thus be attributed to the corresponding alkoxide derivative. Unlike all other alkyl carbonates examined, the presence of a small amount of Li carbonate as a Li surface impurity led to the formation of detectable amounts of the Li alkyl carbonate derivative following exposure to PC. Similar experiments involving gamma-BL yielded IRAS and XPS features consistent with Li butyrate and a derivative of a cyclic beta-keto ester anion of Li as the main reaction products. The conclusions emerging from this study support by and large the mechanism proposed by Aurbach et al. for reactions between Li

    Preeclampsia in Ecuador is an understudied subject since available epidemiological data are scarce. The aim of this study was to describe perinatal outcomes among singleton pregnancies complicated with preeclampsia and eclampsia in a sample of low-income Ecuadorian women. Pregnant women complicated with preeclampsia (mild and severe) and eclampsia (defined according to criteria of the ACOG) delivering at the Enrique C. Sotomayor Obstetrics and Gynecology Hospital, Guayaquil, Ecuador were surveyed with a structured questionnaire containing maternal (socio-demographic) and neonatal data. Perinatal outcomes were compared according to severity of clinical presentation. A total of 163 women with preeclampsia [mild (23.9%), severe (68.7%) and eclampsia (7.4%)] were surveyed. Perinatal mortality and stillbirth rate was similar among studied groups (mild vs. severe preeclampsia/eclampsia cases). However, severe cases displayed higher rates of adverse perinatal outcomes: lower birth Apgar scores, more preterm births, and more low birth weight and small for gestational age infants. Caesarean-section rate and the number of admissions to intensive or intermediate neonatal care were higher in severe cases. A similar trend was found when analysis excluded preterm gestations. In conclusion, in this specific low-income Ecuadorian population perinatal outcome was adverse in pregnancies complicated with severe preeclampsia/eclampsia. PMID:26790539

    Halimeda is a prominent part of the calcifying algae in the coral-reef lagoon ecosystems in the Caribbean. Experiments were performed on the Cayo Enrique Reef off Puerto Rico and in the laboratories of the University of Maryland to study factors influencing the calcification processes. Halimeda opuntia has a higher percentage of calcium carbonate than does Halimeda discoidea and a faster rate of incorporation. Halimeda opuntia and Halimeda discoidea show a stimulation of incorporation by light as well as a diurnal rhythm under identical conditions of illumination. Both phenomena parallel the rhythm of chloroplast migration within the plant. Calcification is also stimulated by the addition of carbon dioxide. Such evidence clearly indicated a light-linked mechanism which could involve photo-synthesis. However other metabolic processes, such as respiration, are also implicated. Aeration alone accelerates calcium incorporation. Nitrogen sources inhibit the incorporation of calcium during the day, indicating that cellular ammonia production is probably not responsible for precipitation. The differential wash-out rates of calcium absorbed during the day compared to those at night support the concept of a 2-step mechanism for calcification. PMID:27096448

    Summer vacations in the Dolomites were a tradition among the professors of the Faculty of Mathematical and Physical Sciences at the University of Roma since the end of the XIX century. Beyond the academic walls, people like Tullio Levi-Civita, Federigo Enriques and Ugo Amaldi sr., together with their families, were meeting friends and colleagues in Cortina, San Vito, Dobbiaco, Vigo di Fassa and Selva, enjoying trekking together with scientific discussions. The tradition was transmitted to the next generations, in particular in the first half of the XX century, and the group of via Panisperna was directly connected: Edoardo Amaldi, the son of the mathematician Ugo sr., rented at least during two summers, in 1925 and in 1949, and in the winter of 1960, a house in San Vito di Cadore, and almost every year in the Dolomites; Enrico Fermi was a frequent guest. Many important steps in modern physics, in particular the development of the Fermi-Dirac statistics and the Fermi theory of beta decay, are related to scientific discussions held in the region of the Dolomites.

    The non-linear conductance of semiconductor heterostructures and single molecule devices exhibiting Kondo physics has recently attracted attention [1,2]. We address the observed sample-dependence across various systems by considering additional electronic contributions present in the effective low-energy model underlying these experiments. To this end we develop a novel version of the superperturbation theory [3] in terms of dual fermions on the Keldysh contour. We analyze the role of particle hole asymmetry on the transport coefficients. Our approach [4] systematically extends the work of Yamada and Yosida and others to the particle-hole asymmetric Anderson model and reproduce the exactly solvable resonant level model and the special case considered in [5]. It correctly describes the strong coupling physics and is free of internal inconsistencies that would lead to a breakdown of current conservation. [4pt] [1] M. Grobis et al., Phys. Rev.

    The origins of New Spain Inquisition whose jurisdiction extended also to Philippine Islands, are related herein. Physicians and surgeons who worked as Inquisition officers are discussed, from the first Dr. Juan de la Fuente who was appointed on May 9, 1572, to Dr. Pedro del Castillo, appointed on September 24, 1644. Likewise, physicians and surgeons judged by the Holy Office are mentioned. During the XVI century, those judged were few and insignificant personages, the first was the Irish Protestant William Corniels a barber surgeon, who arrived with the John Hawkins' pirate fleet in 1568 and settled in Guatemala. Some physicians and surgeons were judged as "Judaizers" during the first half of the XVII century. Many physicians and surgeons were prosecuted in Mexico, as well as in the Philippine Islands, in the second half of the XVIII century because they were Freemasons or supporters of French Revolution ideology. Among those was the unfortunate Dr. Enrique Esteban Morel, who introduced into Mexico the method of antivariolar inoculation at the time of the great epidemic out-break of 1779. It should be a gesture of justice to build a memorial in the ancient Inquisition Palace to honor this Public Health's worthy physician. PMID:12666414

    Reductionism is a constitutive feature of the "standard view" or inherited conception in philosophy of science, such as Enrique Marí says in his book "Elements of comparative epistemology". Whereas the "standard view" is one of the articulators of scientism - epistemological hegemonic position in the contexts of education, innovation, evaluation and application of techno-scientific knowledge - imposed an analysis of this concept as a necessary condition for its overcoming. This article intends to define the meaning and scope of the epistemological reductionism within the framework of the biomedical sciences, on the basis of their genealogy, and then moving in the explicitation of the multiple ways that invest for, finally, realize the consequences of his naive acceptance - or perhaps downright accomplice, of a great part of the scientific community. The consequences are presented in the field of theory, but very particularly in the field of praxis. Establishing the ethical implications of the epistemological reductionism in the theory and practice of Biomedical Sciences is the objective of this work. PMID:25546646

    In this article, the production of knowledge in the context of socially excluded people exposed to inequality, oppression, and exploitation is problematized. The analysis follows Enrique Dussel's philosophical exegesis of the politics of power and corruption and his vision of a critical transformation of the social political order. The argument is also informed by the work of critical educator Paulo Freire, who elucidates the conditions of oppression and marginalization and highlights the importance of conscientization to develop a critical awareness of these conditions. Hannah Arendt's work on the politics of understanding totalitarianism also assists in the elucidation of the machinery that operates behind oppression to sustain power and inequality. The article emphasizes the need to recognize the inequality of conditions that exists between the producer of knowledge and those who live through inequality and oppression in their lived corporality. A critical transformation of the process of production of knowledge is needed to both acknowledge the conditions that sustain this endeavour in the first place and avoid the corruption of knowledge. A work of conscientization is also necessary among knowledge producers to undertake a critical analysis of inequality that exposes the corruption of power. This analysis needs to examine and unmask the hidden mechanisms that perpetuate inequality and oppression and serve only the interests of a few. The abysmal gaps between the wealthy and the poor within and among countries bespeak a degree of human indifference that reflects a most serious and complex phenomenon that perverts something profoundly human in our societies.

    A newly discovered sequence of lower to middle Miocene rocks from the eastern Bocas del Toro archipelago, western Panama, reveals the timing and environment of the earliest stages in the rise of the Isthmus of Panama in this region. Two new formations, the Punta Alegre Formation (lower Miocene, Aquitanian to Burdigalian) and the Valiente Formation (middle Miocene, Langhian to Serravallian), are here named and formally described. The Punta Alegre Formation contains a diagnostic microfauna of benthic and planktic foraminifera and calcareous nannofossils that indicate deposition in a 2000-m-deep pre-isthmian neotropical ocean from as old as 21.5-18.3 Ma. Its lithology varies from silty mudstone to muddy foraminiferal ooze with rare thin microturbidite layers near the top. The Valiente Formation, which ranges in age from 16.4 to ca. 12.0 Ma, lies with slight angular unconformity on the Punta Alegre Formation and consists of five lithofacies: (1) columnar basalt and flow breccia, (2) pyroclastic deposits, (3) coarse-grained volcaniclastic deposits, (4) coral-reef limestone with diverse large coral colonies, and (5) marine debris-flow deposits and microturbidities. These lithofacies are interpreted to indicate that after ca. 16 Ma a volcanic arc developed in the region of Bocas del Toro and that by ca. 12 Ma an extensively emergent archipelago of volcanic islands had formed. 39Ar/40Ar dating of basalt flows associated with the fossiliferous sedimentary rocks in the upper part of the Valiente Formation strongly confirms the ages derived from planktic foraminifera and nannofossils. Paleobathymetric analysis of the two new formations in the Valiente Peninsula and Popa Island, in the Bocas del Toro archipelago, shows a general shallowing from lower- through upper-bathyal to upper-neritic and emergent laharic and fluviatile deposits from ca. 19 to 12 Ma. The overlying nonconformable Bocas del Toro Group contains a lower transgressive sequence ranging from basal nearshore

    This study was undertaken in the south and western regions of the Amazonas Basin to describe the conodont biostratigraphy and paleoecology of Pennsylvanian carbonate rocks of the marine portion of the Tapajós Group comprising the upper Monte Alegre, Itaituba, and lower Nova Olinda formations. The analyzed area includes one outcrop along the Tapajós river (TAP), two carbonate quarries (QI, QII), and 18 wells (dots 1-18). The conodont fauna is dominated by Idiognathoides sinuatus and Neognathodus symmetricus in the Monte Alegre Formation, followed by Idiognathodus incurvus, Diplognathodus coloradoensis and Neognathodus bassleri in the Itaituba and Nova Olinda formations. The conodont association suggests an Early to Middle Pennsylvanian age to the analyzed section. Relative ages attributed to the three lithostratigraphic units using conodonts, palynomorphs, and foraminifers are consistent. Herein are proposed one local taxon-range zone of Idiognathodus incurvus in the Itaituba and lower part of the Nova Olinda Formation and one local taxon-range subzone of Diplognathodus coloradoensis in the Itaituba Formation, suggesting a late Bashkirian - Moscovian (Atokan - early Desmoinesian) age to these strata. The Itaituba Formation marks the establishment of large Pennsylvanian marine conditions in the Amazonas Basin and is composed primarily of marine carbonates of abundant fossil content, tidal flat evaporites and siliciclastic thin intervals. Its lower limit, with the Monte Alegre Formation, is characterized by the predominant occurrence of fluvial-deltaic sandstones superimposed on an extensive sequence of aeolian sandstones, siltstones and shales intercalated with the interdune and lakes. From the upper strata of Itaituba Formation the faunal and lithological characteristics indicate the occurrence of a regressive phase culminating in a restricted environment, arid which indicates the Nova Olinda Formation. This is characterized by the occurrence of evaporites

    The data presented here was part of a comprehensive project coordinated by the University of São Paulo School of Medicine. The objective was to identify the sources to the PM2.5 mass in the following cities: São Paulo (classified as a megacity, with 20 million inhabitants); Rio de Janeiro (the second largest city in Brazil, with ten million inhabitants); Belo Horizonte (2.5 million inhabitants); Curitiba (1.8 million inhabitants); Recife (a coastal city in the northeast of the country, with 1.5 million inhabitants); and Porto Alegre (1.4 million inhabitants). For each city, sampling was performed over a period of approximately 2 years (from winter 2007 to winter 2009). At each location, 24-h samples (8:00 AM to 8:00 AM) were collected on 37-mm polycarbonate filters at 10 Lm -1 using a PM2.5 Harvard Impactor, developed at the Harvard School of Public Health. The sampling stations can all be classified as being urban sites (Chow et al. 2002). They were all near streets with high traffic volumes, where there is significant participation not only by the light-duty fleet (gasohol and ethanol emissions) but also by the heavy-duty fleet (diesel emissions). Two of the cities evaluated, Rio de Janeiro and Recife, are near the Atlantic coast. Before and after sampling, the filters were weighed on a microbalance with 1-μg readability (Mettler-Toledo, Columbus, OH, USA). The BC concentrations were determined by optical reflectance with a smoke stain reflectometer (model 43D; Diffusion Systems Ltd, London, UK). It was shown in Sao Paulo that BC is mainly emitted by heavy-duty fleet. Mean PM2.5 concentrations in the cities of São Paulo, Rio de Janeiro, Belo Horizonte, Curitiba, Porto Alegre, and Recife were 28.0, 17.2, 14.7, 14.4, 13.4, and 7.3 μg/m3, respectively. And mean BC concentrations were 10.2, 3.5, 4.6, 4.1, 3.6 and 1.9 in the cities of São Paulo, Rio de Janeiro, Belo Horizonte, Curitiba, Porto Alegre, and Recife, respectively. The BC concentration was used as a

    The development of the galls of the midge Eugeniamyia dispar Maia, Mendonça-Jr. & Romanowski, 1996 (Diptera: Cecidomyiidae) was monitored weekly on its host plant, Eugenia uniflora (Myrtaceae). The work was carried out in the urban area of Porto Alegre, RS, Brazil, from October 1993 to September 1995. Galls were collected from the field and raised in the laboratory to obtain adults. The females oviposit on young leaves of the host plant, with the first instar larvae inducing the gall, which is unilocular. The last instar larvae drop to the soil to pupate and later emerge as adults. The galls occur from late August to early June, when young leaves of the host can be found, with populations peaking during the summer. So far this species is only known from the two southernmost states of Brazil (RS and SC). PMID:12489401

    The equivalent uranium (eU) activity concentration was analysed in selected granite samples at several sites in Porto Alegre, Southern Brazil, to obtain information on the radon ((222)Rn) generation by the aquifer rock matrices. Radon analyses of ground water and soil samples were also performed. Several samples exhibited a dissolved (222)Rn activity concentration exceeding the World Health Organization maximum limit of 100 Bq l(-1). The dissolved radon content in ground waters from the Fractured Precambrian Aquifer System exhibited a direct significant correlation with the eU in the rock matrices, which is a typical result of water-rock interactions. Variation in the soil's porosity was confirmed as an important factor for (222)Rn release, as expected, due to its gaseous nature. Thus, although the calcic-alkaline to alkaline Precambrian granitoid rocks of the study area are important reservoirs for underground resources, they can release high amounts of radon gas into the liquid phase.

    A high rate of Pneumocystis jirovecii colonization was observed in Brazilian cystic fibrosis (CF) patients (13 out of 34; 38.2%) who underwent bronchoscopy between March 2006 and August 2009 at the Hospital de Clinicas de Porto Alegre, Brazil. Bronchoalveolar lavage samples were collected from these patients and studied by nested PCR amplification of the mitochondrial gene coding for the large subunit ribosomal RNA (mtLSUrDNA). The observed rate of colonization was higher than that reported in European populations. Genotypic characterization of the mtLSUrDNA locus revealed a predominance of the polymorphisms 85C/248C (genotype 1) and 85T/248C (genotype 3), with all samples possessing the wild-type genotype of dihydropteroate synthase. These findings suggest that cystic fibrosis patients could be an important reservoir and source of P. jirovecii infection. Further studies are required to elucidate the role of this common fungal colonization in the evolution of CF patients. PMID:22206262

    At the end of the 20th century, telework appears as one of the modalities of flexible work, which is related to new organizational structures as well as to increasing use of technology. It revolutionizes the traditional ways of performing work. Its implementation creates a number of questions to be answered by the organizations and the individuals involved. This article presents a case study on the viability of implementing telework at Procempa (The Data Processing Company of the City of Porto Alegre). The case study analyzes the technical, organizational, psychological, legal, and labor union dimensions. As a result of this study, we can identify the organization's stage of readiness for telework, the conditions under which it would be implemented, and the specific issues of an implementation.

    Objective To evaluate the correlation between glucose-6-phosphate-dehydrogenase (G6PD) deficiency and neonatal jaundice. Methods Prospective, observational case-control study was conducted on 490 newborns admitted to Hospital de Clínicas de Porto Alegre for phototherapy, who all experienced 35 or more weeks of gestation, from March to December 2007. Enzymatic screening of G6PD activity was performed, followed by PCR. Results There was prevalence of 4.6% and a boy-girl ratio of 3:1 in jaundiced newborns. No jaundiced neonate with ABO incompatibility presented G6PD deficiency, and no Mediterranean mutation was found. A higher proportion of deficiency was observed in Afro-descendants. There was no association with UGT1A1 variants. Conclusions G6PD deficiency is not related to severe hyperbilirubinemia and considering the high miscegenation in this area of Brazil, other gene interactions should be investigated. PMID:23569738

    We present an atlas of more than one hundred original images of planetary nebulae (PNe). These images were taken in a narrow-band filter centred on the nebular emission of the [N ii] during several observing campaigns using two moderate-aperture telescopes, at the Complejo Astronómico El Leoncito (CASLEO), and the Estación Astrofísica de Bosque Alegre (EABA), both in Argentina. The data provided by this atlas represent one of the most extensive image surveys of PNe in [N ii]. We compare the new images with those available in the literature, and briefly describe all cases in which our [N ii] images reveal new and interesting structures. The reduced images as FITS files are only available at the CDS via anonymous ftp to http://cdsarc.u-strasbg.fr (http://130.79.128.5) or via http://cdsarc.u-strasbg.fr/viz-bin/qcat?J/A+A/592/A103

    It is a report on the group activities carried out with carriers of varicose ulcer in a health unit in Porto Alegre, Rio Grande do Sul, Brazil. The varicose ulcer presents factors, besides the biological ones, which interfere in the cicatrization, in the relapse cases and in its effective resolution. The proposed activities aimed at producing behavior changes with the intention of achieving self-care, providing information, socializing the participants, and stimulating cooperation, searching for joint solutions, aggregating interdisciplinary spirit and improving the care. Two groups have been formed and a thematic schedule established. The results have showed higher adhesion to the treatment, behavioral changes, and adapted and more effective attitudes of the health team. PMID:17025041

    2011-01-01

    This paper brings a synthesis of some of the main results provided by GRAVAD survey (Teenage pregnancy: multicentric study about youth, sexuality and reproduction in Brazil). GRAVAD is a study about sexual and reproductive behavior among Brazilian youth that interviewed 4,634 individuals in a population survey with a random sample. Women and men between 18 and 24 years old were interviewed in three capitals—Porto Alegre, Rio de Janeiro and Salvador. “Teen pregnancy” is not the consequence of promiscuous sexual activities, as popular beliefs currently state. It is often ignored that amidst the poorer social segments parenthood is seen as a sign of social status, given the lack of professional perspectives. Among the middle class, other sociocultural horizons give parenthood the status of an experience to be lived in later moments of live, when one's professional and financial lives have been consolidated.

    The Asian subterranean termite, Coptotermes gestroi, originally from northeast India through Burma, Thailand, Malaysia, and the Indonesian archipelago, is a major termite pest introduced in several countries around the world, including Brazil. We sequenced the mitochondrial COII gene from individuals representing 23 populations. Phylogenetic analysis of COII gene sequences from this and other studies resulted in two main groups: (1) populations of Cleveland (USA) and four populations of Malaysia and (2) populations of Brazil, four populations of Malaysia, and one population from each of Thailand, Puerto Rico, and Key West (USA). Three new localities are reported here, considerably enlarging the distribution of C. gestroi in Brazil: Campo Grande (state of Mato Grosso do Sul), Itajaí (state of Santa Catarina), and Porto Alegre (state of Rio Grande do Sul).

    The article is part of a qualitative study analisys developed in 2009 aiming at investigating the demand of emergency calls to the Emergency Mobile Attendance Service/Porto Alegre (SAMU) that classifies it as non-pertinent. The information was gathered from 16 semi-structured interviews with the subjects of that demand by utilizing as a methodological guideline the Grounded Theory. The article approaches the content of the sub-category "Entering into conflict with SAMU regulation in the evaluation of life-threatening", by focusing the divergences between the regulation and the users' perception about the operation of the service and the meaning of "life-threatening", factors implied in the construction of the non-pertinent demand. The importance of Nursing within this scenery is in its competence to perform education actions about first aid and to participate in projects among sectors which are able to intervene in situations that generate vulnerability.

    The present study relates the acquisition of oral language to the development of writing in 236 children of a private school in the city of Porto Alegre, Brazil. The objective of this research was to identify non-linguistic factors involved in phonological acquisition and to describe the relation of phonological acquisition with alterations of writing. At the age of 6 years, kindergarten students were divided into 2 groups, based on the test of Phonological Evaluation of Children. In the follow-up, at 9 years of age, students were evaluated by means of Balanced Dictation and textual production. The comparison of results from case and control groups showed statistically significant difference as to the number of mistakes made in writing, pointing to the acquisition of oral language as a predictive factor for the development of spelling.

    This study explored risk factors for adolescent dating aggression (ADA) among Brazilian street youth. Forty-three adolescents, between the ages of 13-17 years, were recruited at services centers in Porto Alegre, Brazil. Simultaneous multiple regression revealed that ADA was significantly predicted by adolescent dating victimization, and that this relationship was moderated by peer involvement in dating aggression. Results also revealed that peer involvement in dating aggression did not significantly predict ADA. These findings suggested that having peers who are involved in dating aggression exacerbates the effects of dating victimization on ADA among Brazilian street youth. However, adolescent dating victimization might be a stronger risk factor for dating aggression in this population, because when controlling for the effects of victimization in dating conflicts peer abuse towards romantic partners did not uniquely contribute to ADA.

    The authors analyze male sexual initiation as a time of acquiring knowledge, based on 62 ethnographic interviews with young men (18-24 years) in the cities of Porto Alegre, Rio de Janeiro, and Salvador, Brazil, as a stage in the GRAVAD Research Project. Adopting an anthropological and comparative perspective, the reports show that men's first sexual experience is a process of physical and social learning by which they acquire technical knowledge on the use of their bodies and skill to relate to others, especially women. These are important milestones in the passage to adulthood. In addition to differences in belonging to various socioeconomic segments, the authors focus on gender relations, especially models of masculinity, demonstrating that a young man's first sexual intercourse is a socially and symbolically striking moment, not limited to a single event, but an experience that involves different levels of learning as part of the process of becoming a man.

    Rangelia vitalii is a piroplasm that infects canines, causing lesions typical of a hemolytic disorder. Two wild canids, a crab-eating fox (Cerdocyon thous) and a Pampas fox (Lycalopex gymnocercus), were presented for necropsy in Setor de Patologia Veterinária at the Universidade Federal do Rio Grande do Sul, Porto Alegre, Brazil. On gross examination, both animals had pale mucosae and moderate tick infestation (Amblyomma aureolatum). There was severe splenomegaly, and the liver had a diffusely orange-reddish lobular pattern. The mesenteric lymph nodes were brownish and slightly enlarged. Structures compatible with R. vitalii were observed in the cytoplasm of endothelial cells in the liver, stomach, heart, kidney, lungs, lymph nodes, and bladder. The agent was characterized by PCR and genetic sequencing of liver samples and ticks. We show that parasitism with R. vitalii follows an epidemiologic cycle in which wild canids act as reservoirs.

    This study aims to investigate the relationship between abortion and experiences of sexual coercion. The data came from GRAVAD, a household survey with a stratified random sample of young women (18-24 years) in Rio de Janeiro, Porto Alegre, and Salvador, Brazil. The sample used in this article included 870 interviews of women who reported having become pregnant. Abortion was associated with: a reported experience of sexual coercion, more schooling, failure to obtain first information about sex from parents, and a history of more pregnancies and sexual partners. The association between abortion and sexual coercion reflects a situation of gender vulnerability and reveals young women's precariousness in sex negotiation and reproduction. A veil of silence in public agencies concerning sexual coercion helps perpetuate young women's vulnerability, as it blocks access to the appropriate educational, legal, and health services.

    A qualitative study aimed at describing the situations experienced and the ethical dilemmas of nurses in the process of referring and receiving hospitalized patients by court order who require admission to the Intensive Care Unit (ICU). A partially structured interview was conducted with 10 nurses who worked in the ICU and 10 who worked in the Emergency Room (ER) in public and private hospitals in the metropolitan area of Porto Alegre, Brazil. The data was analyzed following the Semantic Analysis. The results indicated that nurses experienced ethical dilemmas associated with problems of overcrowding in emergency rooms and ICUs, poor specialized technology and orientation as to the benefits provided by law. We concluded that it is essential for nurses to participate in discussions that allow the planning of the different instances that have been promoting this often chaotic situation. PMID:23781732

    In this work we study cell adhesion, proliferation and cell morphology of endothelial cell cultured on poly-L-lactide acid (PLLA) modified by heavy ion irradiation. Thin films of PLLA samples were irradiated with sulfur (S) at energies of 75 MeV and gold (Au) at 18 MeV ion-beams. Ion beams were provided by the Tandar (Buenos Aires, Argentina) and Tandetron (Porto Alegre, Brazil) accelerators, respectively. The growth of a monolayer of bovine aortic endothelial cells (BAEC) onto unirradiated and irradiated surfaces has been studied by in vitro techniques in static culture. Cell viability and proliferation increased on modified substrates. But the results on unirradiated samples, indicate cell death (necrosis/apoptosis) with the consequent decrease in proliferation. We analyzed the correlation between irradiation parameters and cell metabolism and morphology.

    Several recreational surface waters in Salta, Argentina, were selected to assess their quality. Seventy percent of the measurements exceeded at least one of the limits established by international legislation becoming unsuitable for their use. To interpret results of complex data, multivariate techniques were applied. Arenales River, due to the variability observed in the data, was divided in two: upstream and downstream representing low and high pollution sites, respectively; and Cluster Analysis supported that differentiation. Arenales River downstream and Campo Alegre Reservoir were the most different environments and Vaqueros and La Caldera Rivers were the most similar. Canonical Correlation Analysis allowed exploration of correlations between physicochemical and microbiological variables except in both parts of Arenales River, and Principal Component Analysis allowed finding relationships among the 9 measured variables in all aquatic environments. Variable’s loadings showed that Arenales River downstream was impacted by industrial and domestic activities, Arenales River upstream was affected by agricultural activities, Campo Alegre Reservoir was disturbed by anthropogenic and ecological effects, and La Caldera and Vaqueros Rivers were influenced by recreational activities. Discriminant Analysis allowed identification of subgroup of variables responsible for seasonal and spatial variations. Enterococcus, dissolved oxygen, conductivity, E. coli, pH, and fecal coliforms are sufficient to spatially describe the quality of the aquatic environments. Regarding seasonal variations, dissolved oxygen, conductivity, fecal coliforms, and pH can be used to describe water quality during dry season, while dissolved oxygen, conductivity, total coliforms, E. coli, and Enterococcus during wet season. Thus, the use of multivariate techniques allowed optimizing monitoring tasks and minimizing costs involved. PMID:25190636

    Machado-Joseph disease (MJD) is an autosomal dominant, late-onset neurological disorder and the most common form of spinocerebellar ataxia (SCA) worldwide. Diagnostic genetic testing is available to detect the disease-causing mutation by direct sizing of the CAG repeat tract in the ataxin 3 gene. Presymptomatic testing (PST) can be used to identify persons at risk of developing the disease. Genetic counseling provides patients with information about the disease, genetic risks, PST, and the decision-making process. In this study, we present the protocol used in PST for MJD and the relevant observations from two centers: Brazil (Porto Alegre) and Portugal (Porto). We provide a case report that illustrates the significant ethical and psychological issues related to PST in late-onset neurological disorders. In both centers, counseling and PST are performed by a multidisciplinary team, and genetic testing is conducted at the same institutions. From 1999 to 2012, 343 individuals sought PST in Porto Alegre; 263 (77%) of these individuals were from families with MJD. In Porto, 1,530 individuals sought PST between 1996 and 2013, but only 66 (4%) individuals were from families with MJD. In Brazil, approximately 50% of the people seeking PST eventually took the test and received their results, whereas 77% took the test in Portugal. In this case report, we highlight several issues that might be raised by the consultand and how the team can extract significant information. Literature about PST testing for MJD and other SCAs is scarce, and we hope this report will encourage similar studies and enable the implementation of PST protocols in other populations, mainly in Latin America.

    OBJECTIVE: To evaluate inhaler technique in outpatients with asthma and to determine associations between the correctness of that technique and the level of asthma control. METHODS: This was a cross-sectional study involving patients > 14 years of age with physician-diagnosed asthma. The patients were recruited from the Asthma Outpatient Clinic of the Hospital de Clínicas de Porto Alegre, in the city of Porto Alegre, Brazil. The patients completed two questionnaires (a general questionnaire and an asthma control questionnaire based on the 2011 Global Initiative for Asthma guidelines), demonstrated their inhaler technique, and performed pulmonary function tests. Incorrect inhaler technique was defined as the incorrect execution of at least two of the predefined steps. RESULTS: We included 268 patients. Of those, 81 (30.2%) showed incorrect inhaler technique, which was associated with poor asthma control (p = 0.002). Logistic regression analysis identified the following factors associated with incorrect inhaler technique: being widowed (OR = 5.01; 95% CI, 1.74-14.41; p = 0.003); using metered dose inhalers (OR = 1.58; 95% CI, 1.35-1.85; p < 0.001); having a monthly family income < 3 times the minimum wage (OR = 2.67; 95% CI, 1.35-1.85; p = 0.008), and having > 2 comorbidities (OR = 3.80; 95% CI, 1.03-14.02; p = 0.045). CONCLUSIONS: In the sample studied, incorrect inhaler technique was associated with poor asthma control. Widowhood, use of metered dose inhalers, low socioeconomic level, and the presence of > 2 comorbidities were associated with incorrect inhaler technique. PMID:24626265

    2013-01-01

    Background This study characterized the botanical knowledge of artisanal fishers of the Lami community, Porto Alegre, southern Brazil based on answers to the following question: Is the local botanical knowledge of the artisanal fishers of the rural-urban district of Lami still active, even since the district’s insertion into the metropolitan region of Porto Alegre? Methods This region, which contains a mosaic of urban and rural areas, hosts the Lami Biological Reserve (LBR) and a community of 13 artisanal fisher families. Semi-structured interviews were conducted with 15 fishers, complemented by participatory observation techniques and free-lists; in these interviews, the species of plants used by the community and their indicated uses were identified. Results A total of 111 species belonging to 50 families were identified. No significant differences between the diversities of native and exotic species were found. Seven use categories were reported: medicinal (49%), human food (23.2%), fishing (12.3%), condiments (8%), firewood (5%), mystical purposes (1.45%), and animal food (0.72%). The medicinal species with the highest level of agreement regarding their main uses (AMUs) were Aloe arborescens Mill., Plectranthus barbatus Andrews, Dodonaea viscosa Jacq., Plectranthus ornatus Codd, Eugenia uniflora L., and Foeniculum vulgare Mill. For illness and diseases, most plants were used for problems with the digestive system (20 species), followed by the respiratory system (16 species). This community possesses a wide botanical knowledge, especially of medicinal plants, comparable to observations made in other studies with fishing communities in coastal areas of the Atlantic Forest of Brazil. Conclusions Ethnobotanical studies in rural-urban areas contribute to preserving local knowledge and provide information that aids in conserving the remaining ecosystems in the region. PMID:23898973

    One hundred twenty-three of 300 blood samples (41%) taken from Rio Grande wild turkeys (Meleagris gallopavo intermedia) from three locations in southern Texas (Welder Wildlife Refuge, Chaparrosa Ranch, and Campo Alegre Ranch) and subinoculated into domestic broad-breasted white turkey poults were positive for a Plasmodium (Novyella) sp. Analysis of blood films from 350 turkeys revealed Haemoproteus meleagridis in 76% of the birds. A significantly greater mean parasite intensity was observed in birds from Welder Wildlife Refuge. Birds from the Campo Alegre Ranch exhibited a significantly higher prevalence of H. meleagridis than birds from Chaparrosa. The Plasmodium sp. was infective for canaries (Serinus canaria), bobwhites (Colinus virginianus), and ring-necked pheasants (Phasianus colchicus), but would not produce infection in white leghorn chickens (Gallus gallus) or Coturnix quail (Coturnix coturnix). Attempts to infect Culex tarsalis and C. pipiens pipiens were unsuccessful. Asexual erythrocytic synchrony was not observed when blood-induced infections were monitored in two domestic turkey poults every 4 hr for 72 hr. Exoerythrocytic stages were not found upon examination of impression smears and tissue samples taken from brain, liver, spleen, kidney, lung, and bone marrow. The Plasmodium sp. is most similar morphologically to three species in the subgenus Novyella, P. hexamerium, P. vaughani, and P. kempi. The most striking similarities are to P. hexamerium, and involve mean merozoite number, erythrocytic schizont location, and vertebrate host susceptibility. It differs from P. vaughani in being able to infect turkeys and in type of parasitized erythrocytes. Differences to P. kempi include mean merozoite number, and ability to infect pheasants, and its inability to develop inC. pipiens and C. tarsalis.

    Background There are scarce epidemiological data on cardiovascular risk profile of chronic hemodialysis patients in Brazil. Objective The CORDIAL study was designed to evaluate cardiovascular risk factors and follow up a hemodialysis population in a Brazilian metropolitan city. Methods All patients undergoing regular hemodialysis for chronic renal failure in all fifteen nephrology centers of Porto Alegre were considered for inclusion in the baseline phase of the CORDIAL study. Clinical, laboratory and demographic data were obtained in medical records and in structured individual interviews performed in all patients by trained researchers. Results A total of 1215 patients were included (97.3% of all hemodialysis patients in the city of Porto Alegre). Their average age was 58.3 years old, 59.5% were male and 62.8% were white. The prevalence of cardiovascular risk factors observed was 87.5% for hypertension, 84.7% for dyslipidemia, 73.1% for sedentary lifestyle, 53.7% for tobacco use, and 35.8% for diabetes. In a multivariate adjusted analysis, we found that sedentary lifestyle (p = 0.032, PR 1.08 - 95%CI: 1.01-1.15), dyslipidemia (p = 0.019, PR 1.08 - 95%CI: 1.01-1.14), and obesity (p < 0.001, PR 1.96 - 95%CI: 1.45-2.63) were more frequent in women; and hypertension (p = 0.018, PR 1.06 - 95%CI: 1.01-1.11) and tobacco use (p = 0.006, PR 2.7 - 95%CI: 1.79-4.17) were more often found among patients under 65 years old. Sedentary lifestyle was independently associated with time in dialysis less than 12 months (p < 0.001, PR 1.23 - 95% CI: 1.14-1.33). Conclusion Hemodialysis patients in this southern metropolitan Brazilian city have a high prevalence of cardiovascular risk factors resembling many northern countries. PMID:24759948

    Cytogenetic and morphometric analyses were carried out in Hoplias aff. malabaricus specimens from six distinct populations from the lower Paranapanema River basin, located between the states of Paraná and São Paulo, Brazil. Measurements were also taken from a specimen collected in Surinam. In a population from a fish farm station at Universidade do Norte do Parana (EPUNOPAR), two sympatric cytotypes (2n = 40 and 2n = 42 chromosomes) are found. A population from a fish farm station at Universidade Estadual de Londrina (EPUEL) shows 2n = 42 meta-submetacentric chromosomes for males and females with a simple sex chromosome system of XX/XY type. Populations from the Vermelho and Rancho Alegre Rivers, Três Bocas Stream and Paranapanema River have 2n = 39 chromosomes in males and 2n = 40 chromosomes in females, showing a multiple sex chromosome system of X(1)X(1)X(2)X(2)/X(1)X(2)Y type. Twenty morphological variables were studied. These measurements were used for an analysis of the canonical variables and standard analysis of proportional measurements. The most variable measurements among the specimens are the maxilla length (MXL) and the pre-dorsal distance (PDD). Analysis of canonical variables indicates three distinct groups in the first canonical axis formed by: (1) Três Bocas Stream, (2) Rancho Alegre + Vermelho River + EPUNOPAR and (3) EPUEL + Paranapanema River. This axis retained 79.4% of information from the original matrix. Analysis of morphometrics reveals differences among populations from the Paranapanema River basin and between these and the specimen from Surinam. The morphometric and cytogenetic differences among the studied populations suggest a species complex. PMID:20738516

    OBJECTIVE: To determine the efficacy of chest compression accompanied by a 10-cmH2O increase in baseline inspiratory pressure on pressure support ventilation, in comparison with that of aspiration alone, in removing secretions, normalizing hemodynamics, and improving respiratory mechanics in patients on mechanical ventilation. METHODS: This was a randomized crossover clinical trial involving patients on mechanical ventilation for more than 48 h in the ICU of the Porto Alegre Hospital de Clínicas, in the city of Porto Alegre, Brazil. Patients were randomized to receive aspiration alone (control group) or compression accompanied by a 10-cmH2O increase in baseline inspiratory pressure on pressure support ventilation (intervention group). We measured hemodynamic parameters, respiratory mechanics parameters, and the amount of secretions collected. RESULTS: We included 34 patients. The mean age was 64.2 ± 14.6 years. In comparison with the control group, the intervention group showed a higher median amount of secretions collected (1.9 g vs. 2.3 g; p = 0.004), a greater increase in mean expiratory tidal volume (16 ± 69 mL vs. 56 ± 69 mL; p = 0.018), and a greater increase in mean dynamic compliance (0.1 ± 4.9 cmH2O vs. 2.8 ± 4.5 cmH2O; p = 0.005). CONCLUSIONS: In this sample, chest compression accompanied by an increase in pressure support significantly increased the amount of secretions removed, the expiratory tidal volume, and dynamic compliance.

    Background Refractive error is defined as the inability of the eye to bring parallel rays of light into focus on the retina, resulting in nearsightedness (myopia), farsightedness (Hyperopia) or astigmatism. Uncorrected refractive error in children is associated with increased morbidity and reduced educational opportunities. Vision screening (VS) is a method for identifying children with visual impairment or eye conditions likely to lead to visual impairment. Objective To analyze the utility of vision screening conducted by teachers and to contribute to a better estimation of the prevalence of childhood refractive errors in Apurimac, Peru. Design A pilot vision screening program in preschool (Group I) and elementary school children (Group II) was conducted with the participation of 26 trained teachers. Children whose visual acuity was<6/9 [20/30] (Group I) and≤6/9 (Group II) in one or both eyes, measured with the Snellen Tumbling E chart at 6 m, were referred for a comprehensive eye exam. Specificity and positive predictive value to detect refractive error were calculated against clinical examination. Program assessment with participants was conducted to evaluate outcomes and procedures. Results A total sample of 364 children aged 3–11 were screened; 45 children were examined at Centro Oftalmológico Monseñor Enrique Pelach (COMEP) Eye Hospital. Prevalence of refractive error was 6.2% (Group I) and 6.9% (Group II); specificity of teacher vision screening was 95.8% and 93.0%, while positive predictive value was 59.1% and 47.8% for each group, respectively. Aspects highlighted to improve the program included extending training, increasing parental involvement, and helping referred children to attend the hospital. Conclusion Prevalence of refractive error in children is significant in the region. Vision screening performed by trained teachers is a valid intervention for early detection of refractive error, including screening of preschool children. Program

    Andean watersheds in Northern and Central Chile are naturally enriched with metals, many of them associated to sulfide mineralizations related to copper mining districts. The natural and anthropogenic influx of toxic metals into drinking water sources pose a sustainability challenge for cities that need to provide safe water with the smallest footprint. This work presents our study of the transformations of copper in the Yerba Loca-Mapocho system. Our sampling campaign started from the headwaters at La Paloma Glacier and continues to the inlet of the San Enrique drinking water treatment plant, a system feeding municipalities in the Eastern area of Santiago, Chile. Depending on the season, total copper concentrations go as high as 22 mg/L for the upper sections, which become diluted to <5 mg/L downstream. pH ranged from 3 to 5.6 while suspended solids ranged from <10 to 100 mg/L. We used Geochemist Workbench to assess copper speciation and to evaluate the thermodynamic controls for the formation and dissolution of solid phases. A sediment trap was used to concentrate suspended particulate matter, which was analyzed with ICP-MS, TXRF (total reflection X ray fluorescence) and XRD (X-ray diffraction). Major elements detected in the precipitates were Al (200 g/kg), S (60 g/kg), and Cu (6 g/kg). Likely solid phases include hydrous amorphous phases of aluminum hydroxides and sulfates, and copper hydroxides/carbonates. Efforts are undergoing to find the optimal mixing ratios between the acidic stream and more alkaline streams to maximize attenuation of dissolved copper. The results of this research could be used for enhancing in-stream natural attenuation of copper and reducing treatment needs at the drinking water facility.

    The Tri-State Catalysis Society awarded 107 Kokes Travel Awards. The program was very successful and to date this was the most Kokes Travel Awards ever awarded at a North American Catalysis Society Meeting. It provided students who merited an award the opportunity to attend the meeting, present a paper in the form of either an oral presentation or a poster presentation, and to serve the North American Catalysis Society by participating in the organization of the meeting. Students worked very hard during the week of the meeting to make it a success. Financial support for the Kokes awards was provided by DOE, NSF, NACS, as well as the Tri-State Catalysis Society, the latter through fund raising activities, and other donations. AT the meeting, each student received over $1050 in kind to offset the costs of registration fees ($260), hotel accommodations ($295.7), transportation ($400 travel allowance), as well as T-shirts ($20), and banquet tickets ($95 provided by donations from society members). In addition, for the first time, students received certificates that were signed by the President of NACS, Professor Enrique Iglesia, and by the Kokes Awards Chair, Gary Jacobs (see last page). A list of meeting co-chairs (i.e., Uschi M. Graham, Umit S. Ozkan, and Madan Bhassin) and the honorary chair (Burtron H. Davis) was also included on the certificate, along with the name of the recipient. The awardees were chosen on a merit-based guideline which also included the requirements of having a presentation accepted at the meeting and being a student at a North American University. The Richard J. Kokes Student Travel Award Committee (Gary Jacobs, Rodney Andrews, and Peter Smirniotis) with help from the Organizing Committee were able to secure money from four sources as detailed in Table 1. As detailed by our Treasurer, Dr. Helge Toufar of Clariant, the total amount spent was $105,000.

    Investigación Clínica has been published uninterruptedly for 55 years and for this reason, the University of Zulia has recognized the work of its editorial team with the imposition of the Order "Jesus Enrique Lossada". Despite some financial and structural problems we are optimistic because our journal has been included in new international indices and it is connected to the scientific world through the contributions from all continents; by the selfless collaboration of hundreds of domestic and foreign referees who respond with great professionalism; and through the visits to our website, from virtually around the world. Reviewing the SCImago statistical analysis, we found that among the Venezuelan medical journals, Investigación Clínica is first in cites per document (2 years) and second in the H index, and compares favorably with prestigious Latin-American journals. It is noteworthy that both in Venezuela and beyond our borders, the submission of topic reviews has increased in detriment of original papers or contributions. It seems that the lack of financial support to research institutes and universities, has led to a decline in experimental projects, at least in the medical field that occupies this journal, so researchers resort to reviews in their respective fields, as a compensation to maintain their productivity. This has caused that the Editorial Board has limited the reception of reviews to keep intact the percentage of published original contributions. Finally, we would like to think that there are no obstacles that can not be overcome to maintain our excellence in publishing Investigación Clínica. PMID:25920180

    SeaBED is an integrated data set and testing infrastructure for researchers to validate subsurface aquatic remote sensing algorithms. The purpose behind developing SeaBED is to collect multiple levels of image, field, and laboratory data with which to validate physical models, inversion algorithms, feature extraction tools and classification methods for subsurface aquatic sensing using hyperspectral imaging. The focus of this testbed facility is a field site located on Enrique Reef in southwestern Puerto Rico. This field site, which includes a heterogeneous mixture of both coral reef and seagrass habitats, offers a well defined system for evaluating analysis techniques under natural environmental conditions. Data produced from the field site currently includes airborne, satellite, and field-level hyperspectral and multispectral images, in situ spectral signatures, and water bio-optical properties. This data provides a valuable combination of sensing imagery and fully characterized ground truth information for developing and validating remote sensing algorithms. A major accomplishment for SeaBED was the collection of high-resolution hyperspectral imagery and associated ground truth of the near shore reefs and coastal ecosystems in southwestern Puerto Rico in 2007. The mission included 1740 km2 of imagery acquired at 4 m spatial resolution, with 110 km2 enhanced coverage of four science areas at 1, 2, 4 and 8 m spatial resolutions to facilitate investigation of spatial scaling issues and the testing of subsurface unmixing algorithms. We present an overview of SeaBED and also describe particulars of the 2007 data collection campaign, including both image acquisition and field data collection efforts.

    In this study new SHRIMP U-Pb zircon data for the Chácara das Pedras Gneiss in Porto Alegre, southern Brazil are presented. They represent a small exposure of the crust which was intruded by a large volume of orogenic to anorogenic granitoids at ca. 618-562 m.y. in the Eastern Domain of the Dom Feliciano Belt. The Chácara das Pedras tonalitic orthogneiss has geochemical similarities with subduction-related magmatic rocks of continental arcs. They present high Sr initial ratios (∼0.712), negative ɛNd(t = 777) values (∼-6), TDM varying from 1.8 to 2.0 Ga. The igneous protoliths of these orthogneisses were previously considered to be Paleoproterozoic based on an upper intercept age of discordant zircon analyses. In the present study these orthogneisses were re-sampled and re-analyzed in an attempt to obtain more concordant analytical data. The U-Pb zircon analyses were carried out using the SHRIMP IIe at the Laboratório de Geocronologia de Alta Resolução of the Universidade de São Paulo. The U-Pb concordia age obtained for igneous textural domains of the zircon grains is 777 ± 4 Ma. A few analyses on zircon overgrowths give poorly defined late Cryogenian ages of ca. 650 Ma. Older ages, mostly discordant, were obtained in a few zircon cores, showing an upper intercept age of ca. 1.9 Ga. One sample of the Três Figueiras Granodiorite, which crosscut the orthogneiss in the same outcrop, was also investigated. The zircons of this granodiorite are, however, mostly metamitic, preventing the determination of a reliable age. Some concordant analyses from a few grains define ages ranging in the interval between ca. 603 and 1022 Ma. The youngest (ca. 603 Ma) may represent a maximum age for the granodiorite crystallization. Older ages, with discordance <10%, are of 745, 777, 836 and 1022 Ma. The 777 ± 4 Ma age obtained for the Chácara das Pedras orthogneiss is the first Early Cryogenian magmatic age determined for granitoids in the Porto Alegre region, although

    The time of concentration (TC) of an urban catchment is a fundamental watershed parameter used to compute the peak discharge and/or in the hydrological simulation of sewer systems. In the lack of hydrological data for its estimative, several empirical formulae are used, however, almost none of them have been verified in Brazil leading to large uncertainties in the correct value. In this light, were tested several formulae such as the proposed by Kirpich (and a modifications of this equation proposed by the National Transport Bureau of Brazil (DNIT)), U.S. Corps. Of Engineers, Pasini, Dooge , Johnstone , Ventura and Ven T Chow as they are used in Brazil. The verification was accomplished against measured data in 5 sub-basins situated in the Dilúvio basin, a semi urbanized watershed that contains the most developed area of the city of Porto Alegre. All the rainfall stations were active in the period from late 1970's until early 1980's due to the existence of Projeto Dilúvio but today, however, only two of them are still in operation. Porto Alegre is the capital and largest city in the Brazilian southernmost state of Rio Grande do Sul with a population of approximately 1.6 million inhabitants, the tenth most populous city in the country and the centre of Brazil's fourth largest metropolitan area, with almost 4,5 million inhabitants (IBGE, 2010). The city is situated in a humid subtropical climate with high and regular precipitation throughout the year. Most summer rainfall occurs during thunderstorms and an occasional tropical storm, hurricane or cyclone. The results showed an error of around 70% for half of the formulas, with a tendency to underestimate TC values. Among the tested methods, Johnstone had the best overall result, with an average error of 25%, well far from the second, Dooge, with 43% of average error. The best results were obtained in only one basin, Dilúvio, the largest one, with an area of 25km², with an error of just 3% for Modified Kirpich, and

    Although common in other bodies of the solar system, impact craters formed in basaltic terrains are rare on Earth and only a few examples are known. Two of these craters are located south of Brazil, the Vargeão and Vista Alegre impact craters. The Cerro do Jarau structure is not confirmed, but is a possible third Brazilian basaltic crater, formed above the Serra Geral basalt floods of the Paraná Basin like the other two. Cerro do Jarau is a 13 km circular landform that rises over 200 meters above the plains of the "pampas" in southern Brazil. The name, meaning "Jarau hills", is given after the crests of silicified and deformed Botucatu sandstones, which form a semiring of elevated hills in the northern part of the structure. This work focused on the construction of a 3D subsurface geological model that could explain a new set of ground gravimetric data. Bouguer anomalies were calculated from gravity acceleration measured at 313 stations irregularly distributed on the area of the impact structure. A regional component represented by a polynomial trend surface was extracted from the total Bouguer anomalies. The residual Bouguer map (fig. 1) shows a strong positive anomaly with a NE-SW trend, located in the northeastern part of the structure. This gravity feature is not common in other impact structures, being possibly related to a dike intrusion. However, the negative anomaly present in the center of the structure and the circular positive anomaly surrounding the central part of the structure could be related to an impact structure. The positive circular anomaly is not spatially coincident with the edges of the structure, a feature that is also observed at the Vargeão and Vista Alegre impact structures. Density values of basalts, sandstones and breccias were measured from rock samples and each average value were used as constraints for the 3D model developed with the Geosoft® VOXI Earth modelling.This model provided a better understanding of the subsurface design

    Introducción: la elección del método para la evaluación nutricional es fundamental para el correcto seguimiento del estado nutricional de los pacientes sometidos al trasplante de hígado.Objetivos: evaluar y comparar el estado nutricional de los pacientes antes y después del trasplante de hígado por el tiempo de un año para los diferentes métodos de evaluación nutricional.Métodos: se evaluaron los pacientes que se sometieron a un trasplante de hígado en diferentes momentos: pretrasplante, 1, 3, 6 y 12 meses después del procedimiento, en la Hermandad de la Santa Casa de Porto Alegre, Porto Alegre, RS, Brasil. Los métodos utilizados fueron la antropometría, la fuerza de apretón de manos por la fuerza de agarre no dominante (FAM), el espesor del músculo aductor del pulgar y el ángulo de fase (AF) por bioimpedancia eléctrica (BIA). En todas las evaluaciones se tomaron las mismas medidas.Resultados: las evaluaciones se llevaron a cabo en 22 pacientes. Los métodos que mostraron mayor prevalencia de pacientes desnutridos antes del trasplante fueron la FA por BIA (25%), la circunferencia muscular del brazo (CMB) (21,9%) y la circunferencia del brazo (CB) (18,8%). Al comparar el estado nutricional de los pacientes durante el seguimiento, hubo diferencia significativa en los métodos de evaluación de CB, espesor del pliegue cutáneo triciptal y AF por la BIA. Al final del seguimiento, los métodos de evaluación nutricional fueron nuevamente comparados y mostraron de diferencias significativas, siendo la FAM el método de mayor detección de desnutrición.Conclusiones: se sugiere que podría intensificarse el uso del método AF por la BIA en esta población, ya que los resultados están en consonancia con los encontrados en la literatura, siendo significativos, fiables y reproducibles.

    The ethnopharmacology for treatment of parasitic infections facilitates and directs the search for new chemical entities. In this direction, this study evaluated the cytotoxicity in vitro, against trophozoites of Giardia lamblia, of aqueous extracts of leaves Achyrocline satureioides (Lam.) DC., barks of Eugenia uniflora L., aerial parts of Foeniculum vulgare Miller, and barks of Psidium guajava L. These plants are traditionally used for the treatment of diarrhea by the indigenous population Mbyá-Guarani, located at the Lomba do Pinheiro, Porto Alegre, Rio Grande do Sul, Brazil. The in vitro susceptibility qualitative analysis of G. lamblia to aqueous extracts was performed in serial dilutions from 2.5 to 0.02 mg/mL. Results revealed the minimal inhibitory concentrations: 0.313 mg/mL for A. satureioides and E. uniflora, 0.02 mg/mL for P. guajava, and F. vulgare did not present any cytotoxic effect. Quantitative assays of viable trophozoites, showed that A. satureioides presented the highest cytotoxic effect (93.5%), followed by P. guajava (82.2%), and E. uniflora (67.3%). Indigenous Guarani use mainly A. satureioides for the treatment of diarrhea, revealing the conformity with results obtained in vitro. Bioguided assays are necessary to identify the compounds responsible for the activity of the aqueous extract of A. satureioides. PMID:19153765

The study aimed to identify changes in the score of the Braden subscales are associated with the risk of developing PCU. Logistic regression was used in a retrospective cohort study conducted in Hospital de Clínicas de Porto Alegre in adults hospitalized in surgical clinical units from October 2005 to June 2006. We evaluated the records database of 1503 patients with a mean aged 55.5 +/- 16 years, 52.7% female. The incidence of PU was 1.8% and was associated with diabetes and heart failure. There was a higher PU in patients worst in sensory perception, mobility, and activity and the presence of moisture. No association was found between nutrition and PU. Except nutrition, the other Braden sub-scales shown to be predictive of PU. PMID:24015458

    This study investigated the correlations between health-related quality of life and social support in adolescents with type 1 diabetes (T1DM). Participants were 102 adolescents between 12 and 17 years old, who were patients of a healthcare program in the city of Porto Alegre, south of Brazil. Two questionnaires, the KIDSCREEN-52 and the Brazilian version of Social Support Appraisals, were used to evaluate health-related quality of life and social support. Results showed good quality of life and social support levels. Strong correlations were verified between social support and three of the KIDSCREEN-52 dimensions: psychological well-being (r = .63; p < .01); peers and social support (r = .67; p < .01) and school environment (r = .64; p < .01). Analysis of linear regression showed that gender, age and social support are variables associated with health-related quality of life, explaining 52.6% of variance. Results revealed the impact of the disease to young people, and can help to find strategies to improve care in these cases. PMID:26054918

    Since the creation of the Brazilian Headache Society in 1978, substantial developments have taken place in both research and clinical practice in the field of headache medicine in Brazil. The Society now has almost 300 members throughout the country, actively working to improve the health of the general population and, in particular, diagnose and treat headache disorders. In addition, in a few large cities, such as São Paulo, Rio de Janeiro, Recife, Ribeirão Preto, Curitiba, and Porto Alegre, headache specialists have come together to promote research projects and increase knowledge in the field through MSc, PhD, and postdoctoral programs. Furthermore, scientific journals have emerged and books have been published to record and disseminate Brazilian scientific production in headache medicine. In this narrative review, we will briefly describe some important aspects of headache medicine in Brazil from prehistoric times to the present day, discuss the origin of headache medicine as a specialty in Brazil, the principal publications dealing with headache disorders, the use of plants and other unconventional forms of treatment used by faith healers, the main training centers, and the research produced to date by Brazilians. In conclusion, in recent years enormous progress has been made in headache medicine in Brazil stimulating us to review and expand our role in an increasingly international scenario. PMID:25659588

    Two sediment cores were studied from Comprido Lake, a black water floodplain lake located near Monte Alegre City, Eastern Amazonian Basin. The total organic carbon (TOC), nitrogen content (TN), δ13CTOC, sedimentary chlorophyll, diatom record and mineralogical composition revealed different hydrological and climatic regimes during the Holocene. Between 10,300 and 7800 cal yr BP, a dry climate was suggested by low values of TOC and chlorophyll derivatives concentrations that are related to the development of a C4 grasses on unflooded mud banks. A gap in sedimentation due to a complete dryness of the lake occurred between 7800 and 3000 cal years BP corresponding to the Middle Holocene dry phase. From 3000 cal years BP onwards a gradual increase of the TOC, chlorophyll derivatives and Aulacoseira sp. suggest an increase in the productivity and in water lake level due to the high water flow of the Amazon River and the catchment area as well. The Comprido Lake record indicates that the Late Holocene in this region was characterized by a wetter climate, as also observed in other records of the Amazonian Basin.

    Objectives The recurrence of meningiomas is a crucial aspect that must be considered during the planning of treatment strategy. The Simpson grade classification is the most relevant surgical aspect to predict the recurrence of meningiomas. We report on a series of patients with recurrent skull base meningiomas who were treated with the goal of radical removal. Design A retrospective study. Setting Hospital Ernesto Dornelles, Porto Alegre, Brazil. Participants Patients with recurrent skull base meningiomas. Main Outcomes Measures The goal of obtaining aggressive resection (i.e., Simpson grades I and II). Results The average age was 54 years, the mean follow-up period was 52.1 months, and Simpson grades I and II were obtained in 82%. The overall mortality was 5.8%. Transient cranial nerve deficits occurred in 11.7%; the definitive morbidity was also 5.8%. A second recurrence occurred in 5.8%. Conclusions Radical removal of recurrent skull base meningiomas is achievable and should be considered an option with a good outcome and an acceptable morbidity. The common surgical finding that was responsible for recurrence in this study was incomplete removal during the first surgery. We recommend extensive dura and bone removal in the surgical treatment of such recurrent lesions. PMID:27175316

    2012-01-01

    Background In the last twenty years, retrospective studies have shown that perinatal events may impact the individual health in the medium and long term. However, only a few prospective studies were designed to address this phenomenon. This study aims to describe the design and methods of the Impact of Perinatal Environmental Variations in the First Six Months of Life - the IVAPSA Birth Cohort. Method/Design This is a clinical study and involves the recruitment of a birth cohort from hospitals in Porto Alegre, Rio Grande do Sul, Brazil. Mothers from different clinical backgrounds (hypertensive, diabetics, smokers, having an intrauterine growth restricted child for idiopathic reasons, and controls) will be invited to join the study twenty-four hours after the birth of their child. Data on economic, social, and maternal health care, feeding practices, anthropometric measures, physical activity, and neuropsychological evaluation will be obtained in interviews at postpartum, 7 and 15 days, 1, 3 and 6 months of life. Discussion To our knowledge, this is the first thematic cohort focused on the effects of intrauterine growth restriction to prospectively enroll mothers from different clinical backgrounds. The IVAPSA Birth Cohort is a promising research platform that can contribute to the knowledge on the relationship between perinatal events and their consequences on the children's early life.

    Abstract Objective: To evaluate the use of reflex cough PEF as a predictor of successful extubation in neurological patients who were candidates for weaning from mechanical ventilation. Methods: This was a cross-sectional study of 135 patients receiving mechanical ventilation for more than 24 h in the ICU of Cristo Redentor Hospital, in the city of Porto Alegre, Brazil. Reflex cough PEF, the rapid shallow breathing index, MIP, and MEP were measured, as were ventilatory, hemodynamic, and clinical parameters. Results: The mean age of the patients was 47.8 ± 17 years. The extubation failure rate was 33.3%. A reflex cough PEF of < 80 L/min showed a relative risk of 3.6 (95% CI: 2.0-6.7), and the final Glasgow Coma Scale score showed a relative risk of 0.64 (95% CI: 0.51-0.83). For every 1-point increase in a Glasgow Coma Scale score of 8, there was a 36% reduction in the risk of extubation failure. Conclusions: Reflex cough PEF and the Glasgow Coma Scale score are independent predictors of extubation failure in neurological patients admitted to the ICU. PMID:26398756

    Objective. To assess the presence of nonverbal and verbal apraxia in patients with Parkinson's disease (PD) and analyze the correlation between these conditions and patient age, education, duration of disease, and PD stage, as well as evaluate the correlation between the two types of apraxia and the frequency and types of verbal apraxic errors made by patients in the sample. Method. This was an observational prevalence study. The sample comprised 45 patients with PD seen at the Movement Disorders Clinic of the Clinical Hospital of Porto Alegre, Brazil. Patients were evaluated using the Speech Apraxia Assessment Protocol and PD stages were classified according to the Hoehn and Yahr scale. Results. The rate of nonverbal apraxia and verbal apraxia in the present sample was 24.4%. Verbal apraxia was significantly correlated with education (p ≤ 0.05). The most frequent types of verbal apraxic errors were omissions (70.8%). The analysis of manner and place of articulation showed that most errors occurred during the production of trill (57.7%) and dentoalveolar (92%) phonemes, consecutively. Conclusion. Patients with PD presented nonverbal and verbal apraxia and made several verbal apraxic errors. Verbal apraxia was correlated with education levels. PMID:26543663

  18. Permanence or change? The meaning of genetic variation

    PubMed Central

    2000-01-01

    Selected aspects of the evolutionary process and more specifically of the genetic variation are considered, with an emphasis in studies performed by my group. One key aspect of evolution seems to be the concomitant occurrence of dichotomic, contradictory (dialect) processes. Genetic variation is structured, and the dynamics of change at one level is not necessarily paralleled by that in another. The pathogenesis-related protein superfamily can be cited as an example in which permanence (the maintenance of certain key genetic features) coexists with change (modifications that led to different functions in different classes of organisms). Relationships between structure and function are exemplified by studies with hemoglobin Porto Alegre. The genetic structure of tribal populations may differ in important aspects from that of industrialized societies. Evolutionary histories also may differ when considered through the investigation of patrilineal or matrilineal lineages. Global evaluations taking into consideration all of these aspects are needed if we really want to understand the meaning of genetic variation. PMID:10805790

    Spodoptera frugiperda, the fall armyworm, is a very significant polyphagous pest due to the damages it causes, and control difficulties. Lack of information about its impact on sweet corn motivated a comparison of its biology, with respect to the larval and pupal stages, among the genotypes ELISA, BR 400 (sweet corns), and BR PAMPA (field corn). In laboratory conditions (25 +/- 1 masculine C; 70 +/- 10% RH; photophase 12 hours), 35 caterpillars were individualized and fed daily with 3.14 cm(2) sections of corn leaves from the referred-to genotypes, cultivated in plots in the experimental area of the Departament of Fitossanidade, UFRGS, Porto Alegre, RS from October to November 2000. The caterpillars were weighed daily; after each molt, the cephalic capsules were collected and measured (in width), to establish growth rate; pupae were weighed and sexed when 24 hours old. The duration of the larval instars, the pupal sex ratio, and the mortality of larvae and pupae were evaluated. In the first three instars there were no differences registered in capsule width. In the fourth and fifth instars, capsules of caterpillars kept in BR 400 were smaller. The weight of caterpillars and pupae, instar duration and sex ratio did not differ among the genotypes. Pupal phase duration was less in females kept in BR 400. Mortality was greater in the larval phase in ELISA and in the pupal phase in BR PAMPA. PMID:15029373

    Abstract In Brazil, breast cancer is a public health care problem due to its high incidence and mortality rates. In this study, we investigated the prevalence of hereditary breast cancer syndromes (HBCS) in a population-based cohort in Brazils southernmost capital, Porto Alegre. All participants answered a questionnaire about family history (FH) of breast, ovarian and colorectal cancer and those with a positive FH were invited for genetic cancer risk assessment (GCRA). If pedigree analysis was suggestive of HBCS, genetic testing of the BRCA1, BRCA2, TP53, and CHEK2 genes was offered. Of 902 women submitted to GCRA, 214 had pedigrees suggestive of HBCS. Fifty of them underwent genetic testing: 18 and 40 for BRCA1/BRCA2 and TP53 mutation screening, respectively, and 7 for CHEK2 1100delC testing. A deleterious BRCA2 mutation was identified in one of the HBOC probands and the CHEK2 1100delC mutation occurred in one of the HBCC families. No deleterious germline alterations were identified in BRCA1 or TP53. Although strict inclusion criteria and a comprehensive testing approach were used, the suspected genetic risk in these families remains unexplained. Further studies in a larger cohort are necessary to better understand the genetic component of hereditary breast cancer in Southern Brazil. PMID:27223485

    Summary Audio computer-assisted survey instrument (ACASI) has been shown to decrease under-reporting of socially undesirable behaviours, but has not been evaluated in pregnant women at risk of HIV acquisition in Brazil. We assigned HIV-negative pregnant women receiving routine antenatal care at in Porto Alegre, Brazil and their partners to receive a survey regarding high-risk sexual behaviours and drug use via ACASI (n = 372) or face-to-face (FTF) (n = 283) interviews. Logistic regression showed that compared with FTF, pregnant women interviewed via ACASI were significantly more likely to self-report themselves as single (14% versus 6%), having >5 sexual partners (35% versus 29%), having oral sex (42% versus 35%), using intravenous drugs (5% versus 0), smoking cigarettes (23% versus 16%), drinking alcohol (13% versus 8%) and using condoms during pregnancy (32% versus 17%). Therefore, ACASI may be a useful method in assessing risk behaviours in pregnant women, especially in relation to drug and alcohol use. PMID:23970659

    Group-IIIE iron meteorites can be ordered into four categories reflecting increasing degrees of shock alteration. Weakly shocked samples (Armanty, Colonia Obrera, Coopertown, Porto Alegre, Rhine Villa, Staunton, and Tanokami Mountain) have haxonite within plessite, unrecrystallized kamacite grains containing Neumann lines or possessing the ɛ structure, and sulfide inclusions typically consisting of polycrystalline troilite with daubréelite exsolution lamellae. The only moderately shocked sample is NWA 4704, in which haxonite has been partially decomposed to graphite; the majority of the kamacite in NWA 4704 is recrystallized, and its sulfide inclusions were partly melted. Strongly shocked samples (Cachiyuyal, Kokstad, and Paloduro) contain graphite and no haxonite, suggesting that pre-existing haxonite fully decomposed. Also present in these rocks are recrystallized kamacite and melted troilite. Residual heat from the impact caused annealing and recrystallization of kamacite as well as the decomposition of haxonite into graphite. Severely shocked samples (Aliskerovo and Willow Creek) have sulfide-rich assemblages consisting of fragmental and subhedral daubréelite crystals, 1-4 vol% spidery troilite filaments, and 30-50 vol% low-Ni kamacite grains, some of which contain up to 6.0 wt% Co; haxonite in these inclusions has fully decomposed to graphite. The wide range of impact effects in IIIE irons is attributed to one or more major collision(s) on the parent asteroid that affected different group members to different extents depending on their proximity to the impact point.

    Background Infant mortality has decreased in Brazil, but remains high as compared to that of other developing countries. In 2010, the Rio Grande do Sul state had the lowest infant mortality rate in Brazil. However, the municipality of Novo Hamburgo had the highest infant mortality rate in the Porto Alegre metropolitan region. Objective To describe the causes of infant mortality in the municipality of Novo Hamburgo from 2007 to 2010, identifying which causes were related to heart diseases and if they were diagnosed in the prenatal period, and to assess the access to healthcare services. Methods This study assessed infants of the municipality of Novo Hamburgo, who died, and whose data were collected from the infant death investigation records. Results Of the 157 deaths in that period, 35.3% were reducible through diagnosis and early treatment, 25% were reducible through partnership with other sectors, 19.2% were non-preventable, 11.5% were reducible by means of appropriate pregnancy monitoring, 5.1% were reducible through appropriate delivery care, and 3.8% were ill defined. The major cause of death related to heart disease (13.4%), which was significantly associated with the variables ‘age at death’, ‘gestational age’ and ‘birth weight’. Regarding access to healthcare services, 60.9% of the pregnant women had a maximum of six prenatal visits. Conclusion It is mandatory to enhance prenatal care and newborn care at hospitals and basic healthcare units to prevent infant mortality. PMID:25993588

    In the present work we embarked on the evaluation of the Sb/Pb, Ba/Pb and Sb/Ba elemental ratios found in relatively large particles (of the order of 50-150 μm across) ejected in the forward direction when a gun is fired. These particles are commonly referred to as gunshot residues (GSR). The aim of this work is to compare the elemental ratios of the GSR with those found in the primer of pristine cartridges in order to check for possible correlations. To that end, the elemental concentration of gunshot residues and the respective ammunition were investigated through PIXE (Particle-Induced X-ray Emission) and micro-PIXE techniques. The ammunition consisted of a .38 SPL caliber (ogival lead type) charged in a Taurus revolver. Pristine cartridges were taken apart for the PIXE measurements. The shooting sessions were carried out in a restricted area at the Forensic Institute at Porto Alegre. Residues ejected at forward directions were collected on a microporous tape. The PIXE experiments were carried out employing 2.0 MeV proton beams with a beam spot size of 1 mm2. For the micro-PIXE experiments, the samples were irradiated with 2.2 MeV proton beams of 2 × 2 μm2. The results found for the ratios of Sb/Pb, Ba/Pb and Sb/Ba do not correlate with those stemming from the analysis of the primer.

    The genotoxicity of untreated and treated sewage from two municipal wastewater treatment plants (WTP BN and WTP SJN) in the municipality of Porto Alegre, in the southern Brazilian state of Rio Grande do Sul, was evaluated over a one-year period using the Tradescantia pallida var. purpurea (Trad-MCN) bioassay. Inflorescences of T. pallida var. purpurea were exposed to sewage samples in February (summer), April (autumn), July (winter) and October (spring) 2009, and the micronuclei (MCN) frequencies were estimated in each period. The high genotoxicity of untreated sewage from WTP BN in February and April was not observed in treated sewage, indicating the efficiency of treatment at this WTP. However, untreated and treated sewage samples from WTP SJN had high MCN frequencies, except in October, when rainfall may have been responsible for reducing these frequencies at both WTPs. Physicochemical analyses of sewage from both WTPs indicated elevated concentrations of organic matter that were higher at WTP SJN than at WTP BN. Chromium was detected in untreated and treated sewage from WTP SJN, but not in treated sewage from WTP BN. Lead was found in all untreated sewage samples from WTP SJN, but only in the summer and autumn at WTP BN. These results indicate that the short-term Trad-MCN genotoxicity assay may be useful for regular monitoring of municipal WTPs. PMID:22215975

    BACKGROUND Lower limb ulcers are a serious medical and socioeconomic problem throughout the world. One type of chronic wound of the lower extremities is the venous ulcer. Therapeutic methods for treating venous ulcer include the use of the Unna boot. OBJECTIVES To evaluate the effectiveness of the customized Unna boot in the treatment of venous ulcers and to monitor the subsequent development and healing of the lesions. METHODS Prospective exploratory and quantitative longitudinal study, conducted at the "Outpatients Department (Wound Care) of the Grupo da Fraternidade Espírita Irmão Alexandre" in the city of Pouso Alegre (MG), Brazil, in 2008. The sample consisted of 32 patients with venous ulcers who underwent treatment with the Unna boot and 11 patients (control group), who used a simple bandage application. The patients'lesions were monitored over a three month period. RESULTS The average age of the predominently female (65.1%) patients was 61.88. From observing the differences in healing times at the three evaluation stages, it was clear that after the initial evaluation the wound area decreased in Groups 1 and 2 (p>0.05). CONCLUSION The use of the customized Unna boot contributes to quicker healing. However, over a period of three months the simple bandage applications were seen to be just as effective as the Unna boot method. PMID:23539002

    The data on the incidence and variability of hereditary haemoglobin (Hb) disorders in Brazil are reviewed. The most common abnormalities are HbS, HbC and beta-thalassaemias. Both homozygotes and compound heterozygotes for these genes (i.e., HbS/HbC disease, S/beta-thalassaemia, C/beta-thalassaemia) are common, owing to the free miscegenation of populations of Mediterranean and African ancestry. The diversity of beta-thalassaemias is similar to that observed in other regions. beta(0)-Thalassaemia is more frequent than the beta(+) variant among affected individuals. Most patients are descendants of Italian immigrants but occasional cases have other racial origins. Patients with thalassaemia major are mostly beta (0) homozygotes, while thalassaemia intermedia is more heterogeneous, including a variety of genotypes. alpha-Thalassaemias are not common although cases of HbH disease have been reported. Isolated examples of several Hb variants have been described, and two abnormal Hb were first found in Brazil: Hb Porto Alegre and Hb Niteroi. PMID:3898485

    Determination of polymyxin susceptibility profile is important to monitor resistance rates and for implementing control measures for polymyxin-resistant carbapenem-resistant Enterobacteriaceae. Some laboratorial methods have been used to determine the polymyxin susceptibility profile. However, the performance of MicroScan WalkAway has been poorly reported for KPC-producing Klebsiella pneumoniae, so far. To evaluate two different methods, Etest and the MicroScan automated system, in determining minimal inhibitory concentration (MIC) of polymyxin among KPC-producing K. pneumoniae isolated from patients in two care units (ICUs) of a tertiary hospital in Porto Alegre, Southern Brazil. A total of 101 KPC-Kb isolates were obtained from rectal swabs and clinical specimens (urine, blood, and endotracheal aspirate). Colistin and polymyxin B MICs were determined using MicroScan WalkAway automated system and Etest, respectively. Discrepant results were resolved by broth microdilution (BMD). MicroScan showed 88.1% of sensitivity for predicting polymyxin B resistance in KPC-producing K. pneumoniae compared to the results obtained by Etest. All discrepant results were tested by BMD and these were concordant with results obtained by Etest. The MicroScan automated system does not seem to be very efficient for the screening of polymyxin-resistant isolates once an inappropriate sensitivity is achieved. The results presented here show the need for confirmation of the susceptibility profile by use of a dilution method (Etest or BMD). PMID:26361367

    The aim of this study was to develop and validate a SYBR Green qPCR assay to detect and quantify a fragment of the 18S rRNA gene of Rangelia vitalii in canine blood. Repeatability of the qPCR was determined by the intra- and inter-assay variations. The qPCR showed efficiency of E=101.30 (r(2)=0.996), detecting as few as one copy of plasmid containing the target DNA. Specificity of the assay was performed using DNA samples of Babesia canis, B. gibsoni, Ehrlichia canis, E. ewingii and Leishmania sp. No cross-reactivity was observed. Field samples consisting of blood from 265 dogs from Porto Alegre, Brazil were also tested. A total of 24 (9.05%) samples were positive for R. vitalii. Amplicons of 50% of positive samples were confirmed to be R. vitalii by Sanger sequencing. The positive samples had an average of 3.5×10(5) organisms/mL of blood (range: 1.27×10(3)-1.88×10(6)) based on the plasmid-generated standard curve. In conclusion, the SYBR Green qPCR assay developed herein is sensitive and specific and can be used as a diagnostic tool for detection and quantification of R. vitalii in canine blood samples.

    This paper presents the results of the structured interview phase of the National Abortion Survey (PNA-interviews), describing the itineraries, methods and social and demographic profile of women who had at least one illegal abortion. Structured interviews were conducted during the years 2010 and 2011 in five state capitals (Belem, Brasilia, Porto Alegre, Rio de Janeiro and Salvador) with 122 women aged between 18 and 39 who had abortions. It is a non-probabilistic sample controlled by six parameters in accordance with level of education and age to reflect the social and demographic structure found in the PNA ballot-box questionnaire phase. The majority of women interviewed had had only one abortion, but 1 in every 4 had two abortions and 1 in every 17 had a third one. The majority of abortions are among women under 19 years of age who already had children and a higher incidence is found among black women. The most common test for pregnancy is beta-HCG blood test, the pharmacy urine test and ultrassound. The prevailing method for induction is a combination of teas and misoprostol (called Cytotec in Brazil), followed by hospital assistance after induction. Women are usually helped by a relative or their partners and several women reported helping other women to have abortions. PMID:22872325

    Free-living amoebae (FLA) are widely distributed in soil and water. A few number of them are implicated in human disease: Acanthamoeba spp., Naegleria fowleri, Balamuthia mandrillaris and Sappinia diploidea. Species of Acanthamoeba can cause keratitis and brain infections. In this study, 72 water samples were taken from both hot tubs and thermal swimming pools in the city of Porto Alegre, RS, Brazil, to determine the presence of Acanthamoeba in the water as well as perform the phenotypic and genotypic characterization of the isolates. The identification of the isolates was based on the cysts morphology and PCR amplification using genus-specific oligonucleotides. When the isolates were submitted to PCR reaction only 8 were confirmed as belonging to the genus Acanthamoeba. The sequences analysis when compared to the sequences in the GenBank, showed genotype distribution in group T3 (12,5%), T5 (12,5%), T4 (25%) and T15 (50%). The results of this study confirmed the presence of potentially pathogenic isolates of free living amoebae in hot swimming pool and spas which can present risks to human health. PMID:27078644

    Access to medical care is sometimes very difficult to be reached from people living in rural and underserved areas. This problem is very well known in rural areas in Brazil. Citizens have no access to health care. They have to travel hundreds of kilometres to receive medical care. In this paper, we will propose a medical network based on state-of-the-art medical imaging application that addresses the problems of providing health care from a distance. Additionally, we are going to show preliminarily results of the first year of the system deployment and utilization in undeserved regions in Brazil. The total number of patients submitted to ultrasound examinations, during the 10 months of projects' medical trials, is 321. The exams have begun with the elderly people (hypertension and diabetes cases) with 90% above 50-years-old. Fifty-four percent were male and 46% were female. From those exams, 67 exams (21%) needed a second medical opinion and were transmitted to Santa Casa hospital in Porto Alegre, Brazil, one of the referral medical centres. From those second opinions of Santa Casa, 12 exams had to be repeated since the acquired images were not sufficient to give a correct diagnosis. The Lagoa Tres Cantos medical doctor performed also preventive exams with patients who had not presented any symptoms (70%).

    We conducted a survey of the malaria vectors in an area where a power line had been constructed, between the municipalities of Porto Velho and Rio Branco, in the states of Rondônia and Acre, respectively. The present paper relates to the results of the survey of Anopheles fauna conducted in the state of Rondônia. Mosquito field collections were performed in six villages along the federal highway BR 364 in the municipality of Porto Velho, namely Porto Velho, Jaci Paraná, Mutum Paraná, Vila Abunã, Vista Alegre do Abunã, and Extrema. Mosquito captures were performed at three distinct sites in each locality during the months of February, July, and October 2011 using a protected human-landing catch method; outdoor and indoor captures were conducted simultaneously at each site for six hours. In the six sampled areas, we captured 2,185 mosquitoes belonging to seven Anopheles species. Of these specimens, 95.1% consisted of Anopheles darlingi, 1.8% An. triannulatus l.s., 1.7% An. deaneorum, 0.8% An. konderi l.s., 0.4 An. braziliensis, 0.1% An. albitarsis l.s., and 0.1% An. benarrochi. An. darlingi was the only species found in all localities; the remaining species occurred in sites with specific characteristics. PMID:26200969

    Large cities' noise is considered by the World Health Organization to be the third most hazardous pollution, preceded by air and water pollution. In urban centers, in general, and especially in developing countries such as Brazil, large populations are affected by excessive noise due mainly to traffic flow. The Brazilian Federal Government specifies noise limits, but each state can enforce its own set of noise limits, providing they are lower. The rapid economic growth, together with large migration of northern Brazilians to the developing southern urban areas in search of more lucrative jobs in construction and industrial sectors, resulted in a fast increase in activities such as vehicle and bus traffic, home construction, and development of all necessary infrastructures to support this growth. Urban noise in Brazil has been receiving the attention of national authorities only since 1990, when the Federal Government approved the first ``Program of Community Silence,'' based on ISO R 1996-1971. This paper highlights the noise situation in the five largest and most populated cities in Brazil: Sao Paulo, Rio de Janeiro, Belo Horizonte, Porto Alegre and Curitiba [Zannin et al., Appl. Acoust. 63, 351-358 (2002)].

    It is an on-going practice in the pediatric ICUs to obtain and to maintain a working artificial airway. Nevertheless this procedure bears not infrequent risks of accidental extubation (AE) which ranges in several services from 0.9 to 3.3 for each 100 days of intubation. The risk factors that are involved in AE are related to: sedation level, age-group, intubation path, and others. The purpose of the authors in this article was to observe the incidence of AE in their service and to compare the relative risk in the rate of AE among orotracheal and nasotracheal intubation population. A prospective study was taken during six months, in which every patients with artificial airway admitted at the PICU of the Santo Antonio Hospital in Porto Alegre (Brazil) was included except those with tracheostomy. The total number of cases were 673 patients-day with artificial airway, with an average of 3.7 patients with tracheal tube per day. In the period there were 18 AE, with a rate of 2.7 AE/ 100 days. The incidence rate of AE in the orotracheal group was 3.1% and 1.6% in the nasotracheal group with no statistically significant difference (p=0.6). The authors concluded that the pathway of intubation in their study does not carry any additional risk in the incidence of accidental extubation. PMID:14689021

    Thirty Boophilus microplus strains from various geographic regions of Brazil, Argentina, Uruguay, Venezuela and Colombia were analyzed for the bm86 and bm95 gene. A fragment of cDNA of 794 base pairs of the parasite larvae, included between nucleotides 278-1071s, was amplified and cloned on the pGEM-T vector. Two random clones were sequenced for each population and the nucleotides 278-1071 and predicted amino acid sequences compared with the bm86 and bm95 genes. Variations from 1.76 to 3.65% were detected in the nucleotides sequence when compared with the homologous sequence of the bm86 gene and a 3.4-6.08% in the homologous amino acid sequence of the Bm86 protein. When the sequences obtained were compared with the bm95 gene, variations from 0.50 to 3.15% were detected. Variations from 1.14 to 4.56% were detected for the Bm95 protein homologous sequences in the deduced amino acid sequence. Only five of the 30 strains analyzed presented two different types of alleles expressed and the two alleles of the Alegre population and allele 1 of the Betim population were the most divergent of all those analyzed.

    The presence of tooth root remains is a common clinical finding among elderly patients and may reflect a need for treatment. The scope of this study sought to explore the association between the presence of tooth root remains and self-reported oral health among the elderly. Secondary data from two sanitary districts of Porto Alegre, State of Rio Grande do Sul, were analyzed. A conceptual theoretical model was used in the analysis to assess factors related to self-perceived oral health: gender, age, education, marital status, smoking habit, alcohol consumption, demand for oral health care, participation in community groups, family economic self-sufficiency, oral health service accessed, number of teeth and the presence of tooth root remains. The statistical data were analyzed using Chi-square and Poisson Regression tests (95% CI analysis; α 5%). The sample consisted of 849 elderly individuals with a mean age of 69.7 years (± 7.2); 14.5% of the elderly had tooth root remains and 60.7% reported good self-perceived oral health. According to the hierarchical analysis, the absence of tooth root remains was associated with good oral health perception. The qualification and expansion of health care provided should be considered in order to allow planning actions to ensure the maintenance of good oral health for the elderly. PMID:26691792

    The purpose of this investigation was to unveil the feelings of medical students while facing the phenomena of death, and also the meaning of these experiences on their lived-world and its implications to their academic training. The investigation was carried out with 10 students who are regularly registered in the Medical School of the Pontificia Universidade Católica do Rio Grande do Sul (PUCRS), Porto Alegre, Brazil, attending between the 3rd and the 6th year. The qualitative approach, with phenomenological basis, along with theoretical assumptions of Merleau-Ponty and the information analysis method proposed by Giorgi (1988) and Comiotto (1992), disclosed five phenomenological essences: The meanings of death; Conflict between life and death; Feelings experienced on the interfaces of death; Medical training; Personal transformation as a path to professional transformation. The findings of this study evidence the feelings and their implications to the process of personal and professional development of the students as primordial and undeniable phenomenon. Considering this relevance, a psycho-pedagogical proposal is presented to educate feelings. PMID:11998471

    The leprosis disease shows a viral etiology and the citrus leprosis virus is considered its etiologic agent. The disease may show two types of cytopatologic symptom caused by two virus: nuclear (CiLV-N) and cytoplasmic (CiLV-C) types. The aim of this study was to compare the morpho-anatomical differences in the lesions caused by leprosis virus-cytoplasmic and nuclear types in Citrus sinensis (L.) Osbeck 'Pêra'. Leaf and fruit lesions were collected in Piracicaba/São Paulo (cytoplasmic type) and Monte Alegre do Sul/São Paulo and Amparo/São Paulo (nuclear type). The lesions were photographed and then fixed in Karnovsky solution, dehydrated in a graded ethylic series, embedded in hydroxy-ethyl methacrylate resin (Leica Historesin), sectioned (5 microm thick), stained and mounted in synthetic resin. The digital images were acquired in a microscope with digital video camera. Leaf and fruit lesions caused by the two viruses were morphologically distinct. Only the lesion caused by CiLV-N virus presented three well-defined regions. In both lesions there was the accumulation of lipidic substances in necrotic areas that were surrounded by cells with amorphous or droplets protein. Only leaf and fruit lesions caused by CiLV-N virus exhibited traumatic gum ducts in the vascular bundles. PMID:20563430

    This study aimed at assessing the relationship between dental pain and the reason for using dental services and oral health quality of life in people aged 50 to 74 years in southern Brazil. A cross-sectional population-based study was conducted with 720 individuals aged 50 to 74 years, living in three health districts in the city of Porto Alegre. Dental impacts on daily life and sociodemographic data were assessed using structured interviews. The Oral Impacts on Daily Performance - OIDP instrument was used to measure oral impacts. The information was analyzed by Poisson regression with robust variance adjustment, taking into account cluster sampling. Dental pain was present in 32.5% of those reporting an oral impact on their daily activities. Dental pain most frequently affected talking (37.6%), cleaning teeth and gums (37.0%) and enjoying the companionship of people (36.5%). After adjustments to the multivariate analysis, the reason for dental visits due to dental pain was found to have a high impact on daily activities [RP 1.68 (1.11 - 2.54]. PMID:27556550

    Spittlebugs are the leading cause of damage to tall grasses. Annual losses are estimated to reach 2.1 billion dollars in sugarcane crops and grazing land throughout the world. Correct identification of these species is difficult due to similarities in color, body size and male genitalia. Molecular markers have been useful in the identification and assessment of genetic diversity of many species. We investigated the genetic diversity of the spittlebug species Mahanarva fimbriolata, M. spectabilis and M. liturata and looked for markers that could aid in their identification. DNA from 34 spittlebug specimens, collected from six different regions of Brazil (Brasília, Campo Grande, Valença, Presidente Prudente, Juiz de Fora, and Porto Alegre), was analyzed with 29 RAPD primers, generating 501 polymorphic markers. High genetic variability was found among individuals M. fimbriolata (0.37), M. spectabilis (0.18) and M. liturata (0.69). Species-specific molecular RAPD markers were identified for each of the three species; these could be used as auxiliary tools for their correct identification. PMID:20533195

    OBJECTIVE To analyze evidence of the validity and reliability of a Brazilian Portuguese version of the Quality of Care Scale from the perspective of people with physical and intellectual disabilities. METHODS There were 162 people with physical disabilities and 156 with intellectual disabilities from Porto Alegre and metropolitan region, who participated in the study in 2008. Classical psychometrics was used to independently analyze the two samples. Hypotheses for evidence of criterion validity (concurrent type) were tested with the Mann-Whitney test for non-normal distributions. Principal components analysis was used to explore factorial models. Evidence of reliability was calculated with Cronbach alpha for the scales and subscales. Test-retest reliability was analyzed for individuals with intellectual disabilities through intra-class correlation coefficient and the Willcoxon test. RESULTS The principal components in the group with physical disabilities replicated the original model presented as a solution to the international project data. Evidence of discriminant validity and test-retest reliability was found. CONCLUSIONS The transcultural factor model found within the international sample project seems appropriate for the samples investigated in this study, especially the physical disabilities group. Depression, pain, satisfaction with life and disability may play a mediating role in the evaluation of quality of care. Additional research is needed to add to evidence of the validity of the instruments. PMID:25210817

    La ocultación de la estrella de quinta magnitud 35 Sgr por Júpiter, se produjo el 6 de Marzo de 1996 a las 13 hs. TU. El objetivo era medir el cambio del flujo de la estrella en el ingreso y egreso por el limbo del planeta. Con estos datos se pueden determinar parámetros físicos del planeta (radio, eccentricidad) y de su atmósfera (escala de altura, temperatura, densidad, presión) Para lograr ésto se programó la cámara CCD TH 7896 1024 x 1025 instalada en el telescopio de 1.54 m de Bosque Alegre con el objetivo de lograr 2 imágenes por segundo. De esta forma se obtuvieron 2100 imágenes de la inmersión y otras tantas de la emersión. Hubo que tener grandes precauciones para evitar la saturación del CCD ya que la observación se realizó de día. En este momento las imágenes se encuentran en el Department of Planetary Sciences, Lunar and Planetary Laboratory, University of Arizona, para su reducción.

    The Neoproterozoic shoshonitic and mildly alkaline bimodal volcanism of Southernmost Brazil is represented by rock assemblages associated to sedimentary successions, deposited in strike-slip basins formed at the post-collisional stages of the Brasilian/Pan-African orogenic cycle. The best-preserved volcano sedimentary associations occur in the Camaquã and Campo Alegre Basins, respectively in the Sul-riograndense and Catarinense Shields and are outside the main shear belts or overlying the unaffected basement areas. These basins are characterized by alternation of volcanic cycles and siliciclastic sedimentation developed dominantly on a continental setting under subaerial conditions. This volcanism and the coeval plutonism evolved from high-K tholeiitic and calc-alkaline to shoshonitic and ended with a silica-saturated sodic alkaline magmatism, and its evolution were developed during at least 60 Ma. The compositional variation and evolution of post-collisional magmatism in southern Brazil are interpreted as the result mainly of melting of a heterogeneous mantle source, which includes garnet-phlogopite-bearing peridotites, veined-peridotites with abundant hydrated phases, such as amphibole, apatite and phlogopite, and eventually with the addition of an asthenospheric component. The subduction-related metasomatic character of post-collisional magmatism mantle sources in southern Brazil is put in evidence by Nb-negative anomalies and isotope features typical of EM1 sources.

    The present study examines the effect of race/ethnicity on measurement equivalence of the Everyday Discrimination Scale (EDS; Williams, Yu, Jackson, & Anderson, 1997). Drawn from the Collaborative Psychiatric Epidemiology Surveys (CPES; Alegría, Jackson, Kessler, & Takeuchi, 2008), adults aged 18 and older from four racial/ethnic groups were selected for analyses: 884 non-Hispanic Whites, 4,950 Blacks, 2,733 Hispanics/Latinos, and 2,089 Asians. Multiple-group confirmatory factor analyses were conducted. After adjusting for age and gender, the underlying construct of the EDS was invariant across four racial/ethnic groups, with Item 7 ("People act as if they're better than you are") associated with lower intercepts for the Hispanic/Latino and Asian groups relative to the non-Hispanic White and Black groups. In terms of latent factor differences, Blacks tended to score higher on the latent construct compared to other racial/ethnic groups, whereas Asians tended to score lower on the latent construct compared to Whites and Hispanics/Latinos. Findings suggest that although the EDS in general assesses the underlying construct of perceived discrimination equivalently across diverse racial/ethnic groups, caution is needed when Item 7 is used among Hispanics/Latinos or Asians. Implications are discussed in cultural and methodological contexts. PMID:24708076

    The research program Amazalert was based on information delivered by the IPCC through its 2007 report, which indicates forest degradation processes in the Amazonian region as a consequence of anthropogenic actions. Such processes affecting the structural and functional characteristics of ecosystems would harm environmental services that guarantee, for example, the regulation of climate and the provision of fresh water. A survey was organized, through a multidisciplinary perspective, on the main policies and programs that can affect forest cover in the Amazon. These rules and norms seek to regulate societal actions by defining a developmental model for the region. Although deforestation rates in the Brazilian Amazon have decreased significantly since 2004, some locations maintain high levels of deforestation. In 2013, for example, the municipalities of Monte Alegre, Óbidos, Alenquer, Oriximiná, Curuá and Almeirin, in the northern region of the state of Para, showed the highest rates of deforestation in the Amazon. Managers and stakeholders within these areas are being interviewed to provide insights on how policies are interpreted and applied locally. There is an understanding delay between discourses normalized by federal governmental institutions and claims of local societies. The possible lack of clarity in official discourses added to the absence of a local communicative dynamics cause the phenomenon of incomplete information. Conflicts often occur in local institutional arenas resulting in violence and complex social and historical dissonances, enhanced by other public policies idealized in different temporal and spatial conditions.

    Acanthamoeba is the most common free-living environmental amoeba, it may serve as an important vehicle for various microorganisms living in the same environment, such as viruses, being pathogenic to humans. This study aimed to detect and quantify human adenoviruses (HAdV) in Acanthamoebas isolated from water samples collected from swimming pools in the city of Porto Alegre, Southern Brazil. Free-living amoebae of the genus Acanthamoeba were isolated from water samples, and isolates (n=16) were used to investigate the occurrence of HAdVs. HAdV detection was performed by quantitative real-time polymerase chain reaction (qPCR). HAdVs were detected in 62.5% (10/16) of Acanthamoeba isolates, ranging from 3.24x103 to 5.14x105 DNA copies per milliliter of isolate. HAdV viral loads found in this study are not negligible, especially because HAdV infections are associated with several human diseases, including gastroenteritis, respiratory distress, and ocular diseases. These findings reinforce the concept that Acanthamoeba may act as a reservoir and promote HAdV transmission through water. PMID:27142544

    ABSTRACT Objective: Post-infectious bronchiolitis obliterans (PIBO) is a clinical entity that has been classified as constrictive, fixed obstruction of the lumen by fibrotic tissue. However, recent studies using impulse oscillometry have reported bronchodilator responses in PIBO patients. The objective of this study was to evaluate bronchodilator responses in pediatric PIBO patients, comparing different criteria to define the response. Methods: We evaluated pediatric patients diagnosed with PIBO and treated at one of two pediatric pulmonology outpatient clinics in the city of Porto Alegre, Brazil. Spirometric parameters were measured in accordance with international recommendations. Results: We included a total of 72 pediatric PIBO patients. The mean pre- and post-bronchodilator values were clearly lower than the reference values for all parameters, especially FEF25-75%. There were post-bronchodilator improvements. When measured as mean percent increases, FEV1 and FEF25-75%, improved by 11% and 20%, respectively. However, when the absolute values were calculated, the mean FEV1 and FEF25-75% both increased by only 0.1 L. We found that age at viral aggression, a family history of asthma, and allergy had no significant effects on bronchodilator responses. Conclusions: Pediatric patients with PIBO have peripheral airway obstruction that is responsive to treatment but is not completely reversible with a bronchodilator. The concept of PIBO as fixed, irreversible obstruction does not seem to apply to this population. Our data suggest that airway obstruction is variable in PIBO patients, a finding that could have major clinical implications. PMID:27383929
