ABSTRACT Hepatitis A virus (HAV) infection has been considered one of the leading causes of acute hepatitis. The aim of the present study was to estimate the prevalence of HAV among children and adolescents in a population-based study in the capitals of the States of the North, Southeast and South of Brazil and identify predictive factors for the infection. A multi-stage sampling was used to select subjects aged between 5-9 and 10-19 years. Individual and household levels aside from the level of variables in the areas were collected. The outcome was the total IgG antibodies to HAV levels detected using a commercial Enzyme Immuno Assay (EIA). The associations between HAV and the independent variables were assessed using the odds ratio. A multilevel analysis was performed by GLLAMM using the Stata software. The prevalence of HAV infection in the 5-9 and 10-19 age groups was 28.7% and 67.5%, respectively for the North, 20.6% and 37.7%, for the Southeast and 18.9% and 34.5% for the South Region. The prevalence of HAV increased according to age in all sites. Variables related to education at the individual level (North and South), family and area level (South and Southeast) and family income level (Southeast and South) were independently associated with HAV infection. This emphasizes the need for individualized strategies to prevent the infection.

Abstract The COVID-19 pandemic’s prolonged extension may have had a long-term negative impact on weight and metabolic parameters associated with the effectiveness of bariatric surgery. The aim of this study was to assess the impact of the COVID-19 pandemic on cardiometabolic risk markers and weight outcomes of post-bariatric patients. This is a longitudinal study carried out with patients who underwent bariatric surgery before the COVID-19 pandemic. Anthropometric, lipid, glycemic profile, blood pressure, eating behavior and physical activity parameters obtained through face-to-face consultations from 2019 to 2022 were evaluated. An increase in BMI (p = 0.001), percentage of weight gain (p

A Kappaphycus alvarezii é a quinta macroalga mais cultivada do mundo e tem sido comercialmente cultivada no Estado de Santa Catarina desde 2020. Seu cultivo atualmente tem se voltado à produção de biofertilizante, todavia, a validação deste produto ainda é uma necessidade do setor. Assim, nesse estudo, objetivou-se analisar as respostas morfológica e bioquímica do uso do biofertilizante de K. alvarezii em plantas de manjericão (Ocimum basilicum) cultivadas em sistema hidropônico de produção. Utilizando as concentrações de 1%, 3%, 5% e 7%, com aplicação foliar semanal, constatou-se na análise morfológica que o biofertilizante, nas concentrações 3% e 5%, foi capaz de incrementar o número de nós, diferindo do controle. Além disso, a matéria seca da raiz também foi incrementada quando aplicado 5% do biofertilizante. Na análise bioquímica, observou-se incremento do teor de clorofila (1% e 5%), de açúcares solúveis totais (5% e 7%), do amido total (3%, 5% e 7%), de carboidratos totais (5% e 7%) e aminoácidos totais (5% e 7%) quando comparada ao controle. Esses resultados indicam que o biofertilizante de K. alvarezii pode ser uma alternativa promissora para o setor agrícola.

Kappaphycus alvarezii is a red seaweed used globally in various biotechnological processes. To ensure the content and stability of its bioactive compounds postharvest, suitable drying protocols must be adopted to provide high-quality raw materials for industrial use. This study aimed to analyze the influence of freeze-drying and oven-drying on the total phenolic content (TPC), total flavonoid content (TFC), antioxidant activity (FRAP and DPPH assays), total carotenoid content (TC), and lipase (LA) and protease activity (PA) of K. alvarezii samples collected over the seasons in sea farms in southern Brazil. The freeze-drying technique was found to be more effective regarding superior contents of TPC (39.23 to 127.74 mg GAE/100 g) and TC (10.27 to 75.33 μg/g), as well as DPPH (6.12 to 8.91 mg/100 g). In turn, oven-drying proved to be the best method regarding the TFC (4.99 to 12.29 mg QE/100 g) and PA (119.50 to 1485.09 U/g), with better performance in the FRAP (0.28 to 0.70 mmol/100 g). In this way, it appears that the drying process of the algal biomass can be selected depending on the required traits of the biomass for the intended industrial application. In terms of cost-effectiveness, drying the biomass using oven-drying can be considered appropriate.

Objective: Entrepreneurs are responsible for innovation, but they do not act in the vacuum, the greater the support for their action, the improve the chances of success. Startups - technology-based companies with high potential for growth and impact - are associated with the existence of entrepreneurial ecosystems that facilitate entrepreneurial action. This paper goal is to provide evidence that help to explain why startups fail in an emerging entrepreneurial ecosystem. Method: We perform exploratory research in which entrepreneurs whose startups failed in the emerging entrepreneurial ecosystem of Porto Alegre, Brazil, were interviewed. We complement the analysis with the collection of secondary data. Results: Building on Isenberg’s (2011) six domains, we generate ideas on how each of them in emergent entrepreneurial ecosystem may influence startup mortality. Our results indicate that emerging entrepreneurial ecosystem could be much better in avoiding the premature failure of startups. Policy and Finance are the most problematic domains, while culture, support, and markets are the three middle-ground dimensions. These last three need improvement, but they are not as critical as the first two. Contributions: This paper contributes to the entrepreneurial ecosystems literature by exploring how emergent ecosystems contribute for discontinuity of promising startups. Originality: Besides entrepreneurial mistakes, problems that are out of the entrepreneur control can also cause a venture's death (Cardon et al., 2011). Building on this, we use Isenberg's (2010; 2011) model for understanding the influence of the entrepreneurial ecosystem on the circumstances that entrepreneurs faced that determined their startup failure (Jenkins & McKelvie, 2016). Social Contributions: by better understanding why startups fail in emerging entrepreneurial ecosystems, we support policymakers in their focus on possible improvements of the features that seem most relevant to entrepreneurs. The public agents can then work to provide a better environment for future entrepreneurial endeavors.

ABSTRACT: Carbon capture technologies will play an essential role in reaching a zero-carbon economy by 2050, and the industrial sector is one of the main areas in which these technologies may be deployed. This work aims to identify and analyze the main industrial sectors that have the potential to deploy carbon capture globally. The initial methodology procedure of this paper is organized into three steps: (i) A systematic literature review is conducted using the Scopus database; (ii) followed by a bibliometric study and; (iii) quantification of the potential of carbon capture in all countries. The processed review data showed that iron and steel production is the industrial sector with the highest number of papers (13 papers), followed by cement manufacturing (8 papers). Besides that, the efficiency and type of carbon capture technology deployed were also evaluated. The data found varied by industry sector, with ethanolamine (MEA) or metil diethanolamine (MDEA) post-combustion and chemical looping technology being frequently cited. As the main results, the number of citations indicates that iron and steel production, followed by cement manufacturing, is the most advanced industrial sector in terms of scientific research on deploying carbon capture technologies. In addition, the countries that demonstrated the greatest potential for carbon capture are China (5,700 mtCO2/y) and the United States (2,100 mtCO2/y), followed by India (1,300 mtCO2/y), Russia (807mtCO2/y), Japan (564 mtCO2/y), and South Korea (403 mtCO2/y).

Context: Using forage grass species with complementary growth and resource-use strategies to enhance forage plant diversity in pastures may be an alternative to traditional monocultures in tropical regions. Aims: This study aimed to determine whether a mixture of three perennial tropical forage grasses (Andropogon gayanus cv. Planaltina, Panicum maximum cv. Massai, and Brachiaria brizantha cv. BRS Piatã) could be an alternative to enhance herbage intake rates relative to their respective monocultures. Methods: The treatments corresponded to three perennial tropical forage grasses cultivated as monocultures and as a mixture composed of all three species. Defoliation management corresponded to a pre-cutting height of 35 cm and post-cutting height of 17.5 cm. Key results: The botanical composition of the mixture was dynamic throughout the experimental period, with variations in the proportion of species across seasons. The upper half of the canopy predominantly comprised leaves for all treatments. The canopy structure of the mixture allowed for greater herbage intake rates than monocultures during winter/early spring. Andropogon gambagrass showed lower herbage intake rates than the other treatments. Conclusions: The findings of this study indicate that it is possible to combine tropical forage grass species without compromising canopy structure and grazing animal responses, compared with single-species grass pastures. Implications: The selection of forage species for mixed pastures should consider their phenological cycle, growth, and resource-use strategies to achieve temporal complementarity and provide an optimal grazing environment for animals throughout the year. Increasing pasture biodiversity using forage grass species with complementary traits may be an alternative to traditional monocultures in tropical regions. This study investigated the relationship between pasture characteristics and herbage intake, indicating that combining tropical forage grass species is possible without compromising pasture dynamics and grazing animal responses. By optimizing forage diversity, we highlight the importance of species selection and seasonal complementarity for maintaining pasture structure and providing an optimal grazing environment for animals throughout the year.

Resource efficiency and survivability are critical concerns in elastic optical networks (EONs) with virtualization. In this paper, we investigate some important aspects in network survivability design against single-link failure under dedicated protection and bandwidth squeezing schemes when multiple virtual topologies are employed. We propose a link-path integer linear programming (ILP) formulation to solve the joint virtualization and survivability problem in elastic optical networks for large network instances, and derive some different types of protection for each virtual topology considering a channel-based spectrum approach to solve the spectrum allocation. Besides, we propose a heuristic to find a pair of predefined paths to ILP formulation aiming to minimize the link load. The proposed ILP and heuristic provide effective survivability solutions and spectrum resource savings for a cooperative design of modern survivable virtualized EONs taking advantages of a link-path model.

Purpose – Innovation ecosystems can emerge and grow organically, but the process can also be managed through conscious intervention. Therefore, this study observes different motivations and expectations for each group of actors. The lack of alignment between actors could have a negative influence on the development of innovation ecosystems. This study aims to analyze the coordination strategies of the actors throughout the life cycle of innovation ecosystems. Design/methodology/approach – This study develops and proposes a model for coordinating innovation ecosystems based on the theoretical backgrounds of the ecosystem life cycle and ecosystem coordination. Findings – This study argues that each stage of an innovation ecosystem’s life cycle – inception, launching, growth and maturity – demands different coordination strategies. Initially, networks are simpler and thus the coordination issues are less difficult. However, as the ecosystem evolves and the complexity of the networks increases, a more sophisticated strategy, such as orchestration or choreography, is needed. Research limitations/implications – This is a theoretical study that recommends further research to test this model. Practical implications – The understanding of coordination and stages of the life cycle of an innovation ecosystem can guide actors in the design of strategies for developing of ecosystems. Social implications – The proposed framework could support strategies to engage civil society in actions to develop innovation ecosystems. Originality/value – This study presents a framework to understand the coordination strategies better, considering the stages of an innovation ecosystem’s life cycle.

A membrana espermática é rica em ácidos graxos poliinsaturados, o que a torna sensível à ação de espécies reativas de oxigênio, que podem prejudicar a qualidade seminal dos cachaços. O objetivo do presente estudo foi avaliar o efeito da suplementação de duas fontes de selênio em diferentes doses. Trinta e cinco cachaços foram distribuídos em quatro grupos: (INOR30) 0,30 ppm de selenito de sódio; (COMP30) 0,30 ppm de metal-aminoácido de selênio; (MISTO15+15) 0,15 ppm de selenito de sódio + 0,15 ppm de metal-aminoácido de selênio e (COMP15) 0,15 ppm de metal-aminoácido de selênio. Os ejaculados dos cachaços foram avaliados durante 22 semanas, resultando em 210 amostras avaliadas para volume, motilidade, pH, presença de aglutinação e alterações morfológicas, e 140 amostras para concentração espermática. Os dados foram analisados com medidas repetidas no tempo em modelo misto, em que o tipo de suplementação de selênio, os períodos de avaliação (um período de duas semanas + cinco períodos de quatro semanas) e suas interações foram os efeitos fixos, e o animal e o funcionário que coletou os ejaculados foram os efeitos aleatórios. Os resultados obtidos demonstraram não haver diferença na suplementação de selênio com as fontes e doses utilizadas. Com isso, foi possível verificar que o metal-aminoácido de selênio na dose de 0,15 ppm promove o mesmo efeito das dietas formuladas com 0,30 ppm de selenito de sódio.

Abstract Background: Psoriasis is associated with atherosclerosis and increased cardiovascular risk. Currently, an automated ultrasound, called quantitative intima media thickness, has proven to be a useful method to evaluate subclinical atherosclerosis. Objectives: To compare increased cardiovascular risk in psoriasis patients receiving two types of treatments: Methotrexate and tumor necrosis factor inhibitor and to evaluate the correlation between the Framingham score and quantitative intima media thickness. Methods: Fifty patients with plaque psoriasis were selected from June 2017 to July 2018, divided into two groups, receiving methotrexate and tumor necrosis factor inhibitor. Measurement of abdominal circumference, blood pressure, body mass index and presence of metabolic syndrome were performed. Afterwards, the patients were evaluated for increased cardiovascular risk with the Framingham score and for the quantitative intima media thickness of the carotid arteries. Results: The mean age was 54.8 (±12.5) with a slight male predominance (58%). Overall, 84% of the patients had elevated waist circumference, 82% had a body mass index above ideal, and 50% had a metabolic syndrome. For the correlation between quantitative intima media thickness and Framingham Score, Pearson's linear correlation coefficient was 0.617 (p < 0.001), indicating a moderate to strong positive association. Study limitations: The protective effect of the therapies cited in relation to the increased cardiovascular risk was not evaluated. Conclusions: A moderate to strong positive association was found correlating the Framingham Score values with the quantitative intima media thickness measurement and it is not possible to state which drug has the highest increased cardiovascular risk.

Along with the wide dissemination of geographic information through online Geographic Information Systems (GIS), it is possible to do several spatial analyzes in a quick and interactive way. Although this possibility appears fundamental for the improvement of geography teaching, these platforms have still been little explored in the classroom. In this paper, we present the LAPIG Maps platform as a tool for the development of interactive activities for the teaching of Geography. We discuss its potential as an important auxiliary tool in the theoretical-practical development of the contents, associated with the geographic categories of analysis

O objetivo deste trabalho foi avaliar os efeitos de manejo de uniformização, ordem de nascimento (ON), peso ao nascimento (PN) e suas interações no desempenho de leitões na fase de maternidade. Porcas (n = 25) e suas leitegadas (n = 388 leitões) foram distribuídas em dois tratamentos: UNIF – uniformização de leitões entre leitegadas distintas logo após o nascimento; MBIO – leitões mantidos até 12 horas pós-parto com a mãe biológica. Nos dois tratamentos o efeito da ON foi avaliado em três grupos caracterizados pela ON de 1–6, 7–12 e ≥ 13; o efeito de PN foi avaliado em quatro grupos definidos como Muito leve, Leve, Médio e Pesado. O delineamento foi inteiramente casualizado em esquema fatorial 2 × 3 × 4, totalizando 24 tratamentos com 16 leitões/tratamento, em média. O ganho de peso do nascimento até 72 horas de vida (GP72h) foi maior em MBIO. A quantidade de colostro ingerida (QCI) foi menor em leitões de ON ≥ 13. Em geral, o desempenho dos leitões aumentou em resposta ao aumento do PN. Houve interação entre manejo de uniformização e PN para QCI em relação ao peso corporal (QCIPC), que foi maior em leitões Muito leves em UNIF (27,48% PC) e menor em leitões Pesados em MBIO (16,82% PC). É possível obter bom desempenho de leitões mantendo a leitegada com a mãe biológica até 12 horas pós-parto. A quantidade de colostro ingerida em base absoluta (g) é maior, mas relativa ao peso corporal (% PC) é menor em leitões pesados. Palavras-chave: colostro; desmame; hiperprolificidade; manejo de uniformização; peso ao nascimento; suinocultura.

Objective To analyze the epidemiological profile of patients with spinal cord injury treated at POLEM – Associação de Apoio às Pessoas com Lesão Medular (Association for Supporting People with Spinal Cord Injury). Method The population studied comprised 113 patients with spinal cord injury, of traumatic or nontraumatic etiology, and the data obtained were compared with those of other institutions. Results Of the 113 patients, 70.8% were male and 29.2% female. Traumatic lesions were responsible for 54% of the patients, and nontraumatic for 46%. Of the patients with traumatic injury, 90.2% were male, the main cause being traffic accidents. In nontraumatic lesions, women were the most affected, 51.9%; and dysraphism and myelitis were the main causes (31% and 21%, respectively). Conclusion The results showed an important incidence of spinal cord injury due to trauma, mainly affecting young individuals of productive age and low educational level, representing high economic and social costs. The data found in the present study are similar to those of other studies performed in our country.

Spatial analysis of traffic accidents is fundamental to comprehend and recognize critical points of road sections and hence establish strategies to reduce these occurrences. This study aims to conduct the spatial analysis of the traffic accidents in 2016 at federal highway sections of the state of Goiás, Brazil. The geocoding was performed in a Geographic Information System (GIS) and mapping of the accident data was provided by NURAM/PRF/GO. Kernel’s density estimation method was applied to analyze the spatial variability and was correlated with data of: fleet, number of cars and engine rate. The results revealed that BR-060, specifically between Goiânia and Distrito Federal, and BR-153, which are the areas that not only present the highest density of traffic accidents, but also a high density of the most severe accidents, with cases of death. Despite being under concession and having the best conditions of traffic and inspection by mobile and fixed equipment, these road sections are configured as critical points. Finally, there was no evidence that the fleet, the number of light vehicles or the motorization rate explain the occurrences of accidents in the federal highways of Goiás, in the year analyzed.

In forest plantations, the productive potential of a given site results from the interaction between genetic materials and environmental conditions. Both are fundamental factors for wood quality and Mean Annual Increment. Knowing the performance of different Eucalyptus urophylla commercial clones under different soil conditions is important for forest planning. Our objective is to evaluate the infuence of soil types on Wood Basic Density and Mean Annual Increment - MAI in two E. urophylla clones. We analyzed the Wood Basic Density of 3- to 8-year-old trees and MAI from two clones grown in four soil types in 14 localities of São Paulo state. ANOVA and Tukey test at 5% probability were performed to test the effect of soil type on Wood Basic Density and MAI. Linear and exponential regression equations were performed between Wood Basic Density x MAI and between MAI x Clay Content, respectively. In general, some soils showed signifcant differences in Wood Basic Density, possibly from climatic variation among sites. Also, the MAI increased exponentially with increase of Soil Clay Content (up to about 25 to 35% of clay), but no correlation was observed between MAI and Wood Density.

Atualmente, as redes sociais são um meio de se expressar; poucas pessoas as tinham, contudo isso mudou e, hoje em dia, elas se tornaram uma exigência, sendo utilizadas até mesmo pelas empresas e se tornando um diferencial competitivo. O objetivo do estudo é analisar como as redes sociais influenciam o comportamento e atitude de compra dos universitários de uma instituição pública e outra privada. Foi realizado por meio de uma pesquisa bibliográfica, sendo classificada, quanto à metodologia utilizada, como um estudo quantitativo, mediante amostragem não probabilística e por cotas em duas instituições de ensino superior, uma pública e outra particular, com 100 universitários. Os principais achados indicam que 70% dos acadêmicos concordam que as redes sociais facilitam o contato com o produto; da mesma forma, 70% consideram importante que as empresas tenham redes sociais. Por outro lado, 49% concordam que as redes sociais influenciam na hora da compra e para 47% as lojas oferecem facilidades de vendas por meio delas. Muito embora, a segurança oferecida pelas redes sociais tenha apenas 29% de aprovação e 15% somente acreditem que a qualidade do produto é a mesma que a descrita nas redes sociais. Por fim, entre as redes sociais mais utilizadas para compra aparecem o Whatsapp (48%), o Facebook (34%) e o Instagram (14%). Como contribuição, foi possível entender o comportamento dos acadêmicos, que se trata de um público jovem e mais conectado, o que pode ajudar as organizações a criarem estratégias específicas de acordo com a característica desse grupo.

Under the hypothesis that modifying nitrogen sources and doses could increase nitrogen fertilization efficiency and productivity and improve forage quality, this study aimed to evaluate the morphological composition, structural characteristics and chemical composition of Panicum maximum cv. Massai forage cultivated under different urea sources (common and coated with Policote®) and nitrogen doses (200, 400 and 600 kg ha-1 year-1) during the autumn, winter and spring of 2014 and the summer and autumn of 2015. The experiment was carried out in Seropédica, RJ, under a randomized complete block design in a factorial arrangement (3x2) + 1 with four replications. High nitrogen rates promoted higher percentages of leaf blade dry mass and lower percentages of dead material dry mass in the forage mass and provided higher tiller population density and forage accumulation rate of Massai grass during the studied seasons. The use of coated urea promoted higher levels of crude protein in the forage than did the use of common urea in all seasons. The intensification of nitrogen fertilization reduced the nitrogen use efficiency but benefitted the structural characteristics, forage accumulation and chemical composition of Massai grass forage. The use of coated urea promoted greater of nitrogen use efficiency during all seasons of the year.

O trabalho teve como objetivo avaliar o percentual de áreas verdes nas Regiões Norte, Noroeste e Meia Ponte da cidade de Goiânia-Goiás, Brasil. Foi aplicado o Índice de Áreas Verdes (IAV), conforme princípios metodológicos que utilizam indicadores dependentes da demografia, expressos pela relação de superfícies de áreas verdes por habitantes. Para a quantificação do IAV, foram utilizadas técnicas de interpretação de imagens de sensoriamento remoto na elaboração do mapa de cobertura vegetal, associada à técnica dasimétrica de mapeamento da densidade demográfica. Como resultado, obteve-se a avaliação entre a distribuição espacial do iav, o quantitativo populacional e a qualidade ambiental urbana. Observou-se que existe uma correlação de desigualdade entre o nível quanti-qualitativo dos espaços verdes, em que estes estão subordinados à especulação imobiliária e à sua manutenção. Ideias destacadas: artigo de pesquisa que consiste na aplicação de ferramentas da geotecnologia para o mapeamento do índice de áreas verdes na cidade de Goiânia e sua relação com a qualidade ambiental urbana.

Abstract: Leprosy can be classified according to its operational form as paucibacillary or multibacillary. Bacilloscopy integrates its diagnostic armamentarium. Patients with the disease may present leprosy reactions. This study describes the association of bacilloscopy results and the type of operational classification of leprosy in patients with leprosy reactions. Medical records were analyzed at a reference center between 2010 and 2015. Reactions occurred in almost half of the patients, making their identification important. The bacilloscopic and operational characterization indicates a greater occurrence of leprosy reactions in patients with positive bacilloscopy and also in multibacillary.

Abstract: Brazil is a country with a high prevalence of infectious diseases such as leprosy and leishmaniasis. However, coinfection of these diseases is still poorly understood. We report a case of a patient who presented with lepromatous leprosy and cutaneous-mucosal leishmaniasis at the same period. After clinical, laboratory, and histopathological diagnosis, the treatment was introduced and the patient showed important clinical improvement. He was followed in our outpatient clinic. Both pathologies play an important role in the immune system. Depending on the immune response profile of the host, diseases may present themselves in different ways. In this case, the patient showed a divergent immune response for each disease. We hypothesized that this response is specific for each pathogen.

A retirada da vegetação em diversas áreas do país reduziu os corredores ecológicos. Tal dinâmica identificada em Rondônia eliminou a conectividade entre muitas terras indígenas. Assim, o presente trabalho tem como objetivo propor a delimitação de uma área para instalação de um corredor ecológico entre as terras indígenas Rio Omerê e Tanaru localizadas na porção sul do Estado de Rondônia de forma a conectar essas duas áreas institucionais. Para alcançar os objetivos aplicou-se a modelagem de eventos terrestres em ambiente de um Sistema de Informação Geográfica (SIG) a partir da ponderação das variáveis uso e cobertura, área de preservação permanente e declividade. Os resultados resultaram em oito propostas de corredores ecológicos, em que o Corredor D apresentou menor porcentagem de área antropizada, 28,40% e maior porcentagem de área florestada, 71,61%. Além disso, identificou-se que o comprimento desse corredor foi de aproximadamente 25 km, largura de 2,5 km e ocupou área de 61,84 km².

Abstract Cutaneous metastases from primary internal malignancies represent 0.7-9% of patients with cancer. We report a 65-year-old female patient referred for evaluation of normochromic papules on the trunk and upper limbs that had been present for three months. A skin biopsy revealed diffuse cutaneous infiltration by small round cell tumors. Immunohistochemistry was positive for AE1/AE3, CK7, estrogen receptor and mammaglobin. The final diagnosis was cutaneous metastasis of occult breast cancer, since the solid primary tumor was not identified. The location of the primary tumor can not be determined in 5-10% of cases. In these cases, 27% are identified before the patient’s death, 57% at autopsy, and the remaining 16% can not be located.

The objective of this article was to investigate the perception of esthetic changes in the facial profile of bilateral Class II patients treated with the Modified Thurow Appliance for extraoral treatment. Silhouettes were traced of profiles of patients who initially presented a bilateral Class II molar relationship and who, post-treatment, presented molars in a Class I relationship. Three groups were formed: the first composed of patients with maxillary protrusion (SNA >84°), the second with maxillary retrusion (SNA

Objective: to report clinical and pathological features of patients with colorectal cancer diagnosed during emergency abdominal surgery. Methods: records of 107 patients operated between 2006 and 2010 were reviewed. Results: there were 58 women and 49 men with mean age of 59.8 years. The most frequent symptoms were: abdominal pain (97.2%), no bowel movements (81.3%), vomiting (76.6%), and anorexia (40.2%). Patients were divided into five groups: obstructive acute abdomen (n = 68), obstructive acute perforation (n = 21), obstructive acute inflammation (n = 13), abdominal sepsis (n = 3), and severe gastrointestinal bleeding (n = 2). Tumors were located in the rectosigmoid (51.4%), transverse colon (19.6%), ascendent colon (12.1%), descendent colon (11.2%), and 5.6% of the cases presented association of two colon tumors (synchronic tumors). The surgical treatment was: tumor resection with colostomy (85%), tumor resection with primary anastomosis (10.3%), and colostomy without tumor resection (4.7%). Immediate mortality occurred in 33.4% of the patients. Bivariate analysis of sex, tumor location and stage showed no relation to death (p > 0.05%). Conclusions: colorectal cancer may be the cause of colon obstruction or perfuration in patients with nonspecific colonic complaints. Despite the high mortality rate, resection of tumor is feasible in most patients. Resumo: Objetivo: analisar os aspectos clinicos e patológicos de pacientes operados de cancer colorretal diagnosticados durante operações abdominais de urgencia. Métodos: foram estudados os prontuários de 107 pacientes operados entre 2006 e 2010. Resultados: Foram incluidos 58 mulheres e 49 homens com idade media de 59,8 anos. Os sintomas mais frequentes foram: dor abdominal (97,2%), parade de eliminação de gases e fezes (81,3%), vomitos (76,6%) e anorexia (40,2%). Os pacientes foram divididos em cinco grupos: abdomen agudo obstrutivo (68), abdomen agudo perfurativo (21), abdomen agudo inflamatorio (13), sepsis abdominal (3) e hemorragia digestive baixa (2). Os tumores localizavam-se no rectossigmoide (51,4%), colon transverso (19,6%), colon ascendente (12,1%), colon descendente (11,2%) e 5,6% dos pacientes apresentavam tumors sincronicos. O tratamento cirurgico foi: colectomia com colostomy (85%), colectomia com anastomose primaria (10,3%) e colostomia sem ressecçao do tumor (4,7%). Mortalidade immediate ocorreu em 33,4% dos pacientes. Analise bivariate de sexo, localização do tumor e estadio não foi relacionada a mortalidade (P>0,05%). Conclusões: o cancer colorretal pode ser a causa de obstrução colonica ou perfuração in pacientes com queixas inespecificas. A despeito da alta taxa de mortalidade, a ressecção do tumor pode ser realizada na maioria dos pacientes.

Abstract: Leprosy patients can present reactions during the course of the disease. There are no official data on these reactions in Brazil. We aimed to describe the epidemiological characteristics of patients with such reactions, analyzing information from patient records at a referral center in Campinas (SP), from 2010 to 2015.

AbstractStewart-Treves Syndrome is characterized by the presence of lymphangiosarcoma on limb extremities. Rare, it occurs in 0.5% of patients who have undergone radical mastectomy with axillary node dissection. The main cause is chronic lymphedema with endothelial and lymphatic differentiation, with no direct relationship to breast cancer. Seven years after a radical right-side mastectomy with lymph node dissection and adjuvant therapy, the patient developed a lesion on her right arm. The dermatological examination revealed an erythematous nodule with bleeding surface on chronic right forearm lymphedema. After the biopsy, a lymphangiosarcoma on chronic lymphedema was diagnosed. Infrequent, this syndrome is relevant because of its associated mortality. Early diagnosis is important to improve survival and reduce complications.

O presente artigo faz uma análise, à luz do Sistema de Avaliatividade, do texto "Por que o mundo odeia o Papa Bento XVI?", cuja autoria é atribuída ao Abade Cacqueray. Focaliza-se especificamente o julgamento como uma das formas de se realizar o posicionamento atitudinal do produtor. Destarte, o trabalho preocupa-se com a linguagem que critica ou elogia, que condena ou aplaude o comportamento - as ações, atos, palavras, crenças, motivações - assumidos no texto em foco.

Bone tissue has different models of vascularization, cellular distribution, mineralization and remodeling among mammals species. A variety of dietary habits associated with the mode of locomotion and habitat required from bats the establishment of different flying styles and some skeletal adaptations. This study aimed at examining the microscopic characteristics of mature bone tissue of Glossophaga soricina (Phyllostomidae, Chiroptera). Twelve animals of both genders were used, in which the right humerus were dissected, weighed, decalcified and submitted to routine histological processing. Semi-serial cuts of 5 micrometers were stained with hematoxylin and eosin (H.E.), picrosirius red and silver nitrate 50%. The histological preparations were subjected to histological and histomorphometric analysis. Lacunae density was significantly higher in humerus of females when compared to males (33.96 x 27.80, p = 0.02). Microscopic analysis indicated the presence of parallel collagen fibers distributed in the bone matrix. Lacunes presented various shapes and canaliculi are well distributed and individualized. Few Havers systems and canals were observed. The mature bone tissue of the humerus Glossophaga soricina share microscopic features with other mammals, however, differences in the structural organization are peculiar to this species.

O presente artigo faz parte de uma tradição recente de pesquisas que investigam a avaliação como recurso interpessoal no discurso em contextos dos mais variados. Assim, objetiva uma análise sobre a avaliação e a construção identitária do resenhista em resenhas acadêmicas da área de Linguística a partir da categoria de engajamento articulada por Martin e White (2005). Nesse sentido, o que se sobreleva e investiga, por meio da identificação e interpretação, são os recursos linguísticos pelos quais o resenhista adota uma postura no sentido de valorizar ou não posições que estão sendo referenciadas no texto. O que se observa é o predomínio do endosso e como a avaliatividade nesse gênero pode ser resultado de uma relação cinética de uma estrutura ainda maior em que estão contextualizadas as diversas ciências sociais em geral.

O estudo da avaliatividade — uma abordagem para explorar, descrever e explicar a forma como a linguagem é usada para avaliar, adotar posturas, construir personas textuais e gerenciar posicionamentos interpessoais e relacionamentos — possibilita a compreensão crítica do complexo de valores, costumes, crenças e práticas que constituem o modo de vida de um grupo específico. Destarte, este artigo apresenta uma análise, com base nesse estudo, do discurso do cardeal Joseph Ratzinger — o papa Bento XVI — que oficializa a posição da Igreja Católica em relação aos modelos alternativos de família. Objetiva-se, então, elaborar uma crítica sobre as implicações decorrentes das escolhas linguísticas que apontam a avaliação do pontífice. A despeito de uma reavaliação da postura ético-teológica a ser adotada em relação à homossexualidade, que alguns estudos têm apontado, o que se percebe por meio principalmente de julgamentos é a resistência a qualquer inclinação para o reconhecimento social das formas alternativas de família.

LAND USE AND ITS SOCIO-ENVIRONMENTAL IMPLICATIONS IN THE WETLANDS OF THE ARAGUAIA RIVER (STATE OF GOIÁS, BRAZIL). The Araguaia River is one of the largest in Brazil and certainly the most significant for the state of Goiás. It played a central role in the discovery of, and settlement in, the hinterlands of central Brazil. The Aruaguia river basin, in between its source and its mouth, is usually divided into three segments – High, Middle and Lower Araguaia – to which correspond different types of landscape. The present study focuses on a segment of the Middle Araguaia that stretches from the Registro do Araguaia district (municipality of Montes Claros) to the southern tip of the Bananal island (municipality of São Miguel do Araguaia). The study area occupies an area of 4,430 km² and is characterized by its smooth relief and hydromorphic soils, which are associated with a discontinuous strip of flood plain. Occupation of the study area intensified from the 1960s onwards, and was driven mostly by pastoralists who were attracted to the area by the low price of the land, the public policy of colonization and the physical characteristics of the region. This article presents an environmental characterisation of these wetlands, based on the interpretation of data acquired through remote sensing and a field work. It then discusses the predominant types of land use and their socio-environmental implications. The analysis refers to the year 2007 and indicates the existence of a number of serious threats to the integrity of the wetlands of the Araguaia River, whose relevance in terms of natural heritage has been acknowledged at the national level. In particular, the results show that 61% of the study area is allocated to either cattle farming or agriculture, and that the predominant economic activity, cattle farming, takes up 42% of that area.

Este trabalho objetivou avaliar a "performance" de quatro clones híbridos de Eucalyptus spp., propagados pelas técnicas de estaquia, micropropagação, microestaquia e miniestaquia, quanto às características de crescimento em altura e diâmetro (dap), bem como a produção de biomassa da parte aérea, em teste clonal, instalado em dois locais distintos localizados no norte de Minas Gerais. De acordo com os resultados, pode-se concluir que os efeitos das técnicas de propagação não resultaram em diferenças expressivas no crescimento em altura e dap, nas avaliações aos 4, 8, 16 e 24 meses de idade, dos clones estudados. Em relação à biomassa da parte aérea, os resultados não indicaram uma tendência sobre possíveis efeitos das técnicas de propagação em relação ao comportamento silvicultural dos clones.The objective of the present study was to evaluate the performance of four Eucalyptus spp. hybrid clones, propagated by cutting, micropopagation, microcutting and minicutting techniques. The study evaluated height and diameter growth characteristics, as well as the aerial biomass production, in a clonal test installed in two localities in the north of Minas Gerais State. According to the results, it can be concluded that the effects of propagation techniques did not result in expressive differences in height growth and DBH, at ages 4, 8, 16 and 24 months, for the studied clones. In relation to the aerial biomass, the results did not indicate a tendency for possible effects of the propagation techniques on clone silvicultural performance.

Neospora caninum causes cattle abortion and neurological symptoms in dogs. Although infection is usually asymptomatic, classical neurological symptoms of neosporosis may be associated with encephalitis. This parasite can grow in brain endothelial cells without markedly damages, but it can modulate the cellular environment to promote its survival in the brain. In previous studies, we described that IFN-γ decreased the parasite proliferation and down regulated nitric oxide production in astrocyte/microglia cultures. However, it remains unclear how glial cells respond to N. caninum in the presence of neurons. Therefore, we evaluated the effect of 300 IU/mL IFN-γ or 1.0 μg/mL of LPS on infected rat neuron/glial co-cultures. After 72 hours of infection, LPS did not affect the mitochondrial dehydrogenase activity. However, IFN-γ decreased this parameter by 15.5 and 12.0% in uninfected and infected cells, respectively. The number of tachyzoites decreased 54.1 and 44.3% in cells stimulated with IFN-γ and LPS, respectively. Infection or LPS treatment did not change NO production. On the other hand, IFN-γ induced increased nitrite release in 55.7%, but the infection reverted this induction. IL-10 levels increased only in infected cultures (treated or not), meanwhile PGE2 release was improved in IFN-γ/infected or LPS/infected cells. Although IFN-γ significantly reduced the neurite length in uninfected cultures (42.64%; p < 0.001), this inflammatory cytokine reverted the impairment of neurite outgrowth induced by the infection (81.39%). The results suggest a neuroprotective potential response of glia to N. caninum infection under IFN-γ stimulus. This observation contributes to understand the immune mediated mechanisms of neosporosis in CNS

Atualmente, experiências realizadas em todo o mundo, inclusive no Brasil, já provam a robustez da PowerLine Communication (PLC), apontando que esta tecnologia pode oferecer um largo espectro de aplicações, desde acesso à Internet em banda larga, telefonia, tele-controle, automação residencial, serviços audiovisuais, segurança predial, entre outros, promovendo a integração de diferentes serviços em um único meio físico, sendo um destes a aplicação VoIP. Apesar de está sendo difundida na atualidade, é comprovada a utilização do PLC desde o início do século XX, devido à necessidade das empresas distribuidoras de energia em controlar e monitorar as suas linhas. O presente trabalho visou apresentar uma análise sobre a tecnologia que possibilita transmitir dados e eletricidade em um mesmo meio físico, o PLC. Portanto, com o intuito de comprovar a qualidade deste método foram apresentados alguns estudos no tocante ao fornecimento de telefonia, através de Voice over IP (VoIP), ratificando a posição da PowerLine Communication como uma alternativa de rede de acesso de telecomunicações.
