    Background: Wild animals bred in captivity may develop steatosis due to unbalanced dietary intake and obesity caused by sedentary behaviour. In some rural areas, six-banded armadillos are raised in captivity inside some metal barrels, with restricted space, and are often overfeed. After getting fattening, armadillos they are slaughtered and used as food. Theunfavorable conditions may somehow contribute to likely underlie the development of many diseases, among them we can including hepatic steatosis. The present report aims to describe the pathological fndings of hepatic lipidosis in banded armadillos (Euphractus sexcinctus), bred in captivity.Case: The animals were three female adult six-banded armadillos (Euphractus sexcinctus), caught in the native forest of the city of Natal, Rio Grande do Norte, Brazil and raised in domestic environment in a small enclosure and fed with human food leftovers. After eight months kept in these conditions armadillos had severe obesity and then were donated to the city zoo, where they were quarantined and presented clinical symptoms of anorexia for two weeks, weight loss and exhaustion. After being found dead during daily inspection carried out by the veterinarian zoo, the six-banded armadillos were sent to the Animal Pathology Laboratory of Federal Rural University of the Semi-Arid (UFERSA) for pathological examination.The animals presented with a history of anorexia were extremely obese and the autopsy detected had extensive deposits of fat in the carcass and liver. Histopathologically, the liver cells hepatocytes showed marked intracytoplasmic vacuolization and with peripheral displacement of the nucleus to the periphery, with and positive staining for lipids using scarlet Sudan III. To our knowledge, this is the frst report of hepatic lipidosis in banded.Discussion: Hepatic lipidosis can be categorized into normal liver and mild, moderate, or severe fatty liver. In severe cases, it is estimated that 80% of the hepatocytes are affected. Therefore, we classifed the hepatic lipidosis of the three studied female six-banded armadillos as severe, since the lipids were deposited diffusely. Based on the severity of the lesions and absence of other fndings, we concluded here that hepatic lipidosis contributed to the cause of the six-banded armadil los death. The weight of the animals in this report may be associated with innapropriate enclosure dimensions and a diet based on human food leftovers. Such diet was reportedly composed of rice, beens, spaghetti, and bread, which are food with high levels of carbohydrate. The armadillos of the Euphractus sexcinctus species usually weigh between 3 and 6 kg and hence, the animals of this report showed twice the normal weight. The occurrence of hepatic lipidosis associated with anorexia triggered by a stressful event such as a change of environment and diet armadillos observed in the present study is in agreement with literature data pointing anorexia in obese animals as a major predisposing factors for the occurrence of hepatic lipidosis by promoting energy restriction, peripheral lipolysis and large intake of fatty acids to the liver.Keywords: Euphractus sexcinctus, armadillos, anatomopathology, liver, lipidosis

    O jornalismo enfrenta crises e, apesar da era tecnol√≥gica, persiste distante de muitas popula√ß√Ķes. Debates sobre este contexto, por√©m, s√£o incipientes, o que ensejou-o como tema de investiga√ß√£o. Indagou-se dessarte se tais crises favorecer-se-iam dessa condi√ß√£o incongruente. O trabalho consequente comp√īs-se de estudo da cultura do setor em lugares sem jornalismo ‚Äď os desertos de not√≠cias. O lastro fez-se de revis√Ķes bibliogr√°ficas e de um recorte da referida realidade. Dividiu-se o resultado em tr√™s cap√≠tulos. O primeiro traz os significados de cultura e sublinha o conceito adotado ‚Äď o antropol√≥gico. Adiante, define comunica√ß√£o e din√Ęmicas do bin√īmio cultura-comunica√ß√£o. Ademais, registra a metodologia para interpretar culturas e comunica√ß√£o. O cap√≠tulo segundo demonstra a complexidade do jornalismo em termos simb√≥licos. A seguir, explana como o setor sempre dependeu de centros e institui√ß√Ķes de poder. Aqui, evidenciam-se o etnocentrismo do jornalismo e rea√ß√Ķes poss√≠veis de subalternizados em processos culturais. Outrossim, h√° discuss√Ķes sobre as crises e o futuro. O cap√≠tulo terceiro apresenta o recorte do caso estudado, focando-se em Pernambuco ‚Äď unidade brasileira com aproximadamente 70% dos munic√≠pios como desertos de not√≠cias. Para tal, remonta-se breve hist√≥ria do jornalismo no pa√≠s e no estado e respectivos contextos. O t√≥pico seguinte apresenta a TV Asa Branca ‚Äď empresa ligada √† Globo, um dos maiores conglomerados de m√≠dia do mundo. Grosso modo, assinala-se que o trabalho da emissora foca-se em Caruaru, munic√≠pio-sede. A seguir, exibem-se resultados de inqu√©ritos. Um indicou, em suma, a busca frequente do p√ļblico por not√≠cias e a √≠nfima depend√™ncia em rela√ß√£o ao jornalismo. No outro, para profissionais e grupos afins, perceberam-se sobretudo a falta de diversidade e a pr√°tica do "jornalismo sentado". Munido destes dados e das revis√Ķes, concluiu-se que a cultura do jornalismo causa ou, pelo menos, contribui de modo significativo para as pr√≥prias crises e, ademais, que o setor pode ser antidemocr√°tico.Journalism faces crises and, despite the technological era, remains removed from many populations. Indeed, debates about this topic are incipient, making it one that should be investigated. Thus, the question posed was whether crises would actually benefit from this incongruous condition. The consequent work consisted of studying the journalism culture in places without journalism‚ÄĒthe news deserts. The research was based on bibliographical reviews and a sample from news deserts. The result was divided into three chapters. The first chapter deals with meanings of culture and its anthropological concept. Further on, it defines communication and the culture-communication dynamics. This step also registers a methodology to interpret cultures and communication. The second chapter demonstrates complexities of journalism, on approach to symbols. Then, it explains how this sector has always depended on centers and institutions of power. Here, the text evidences journalism‚Äôs ethnocentrism, and possible dismissals of marginalized populations. Also, there are discussions about crises and the future. The third chapter presents the sample, focusing on Pernambuco‚ÄĒa Brazilian unity where about 70% of its municipalities are news deserts. Then, it shows a brief history of Brazilian journalism, including this state, stressing their contexts. The following text introduces TV Asa Branca‚ÄĒan enterprise associated with Globo, one of the world‚Äôs largest media companies. Roughly speaking, this topic marks its news mostly representing the reality of Caruaru, its host municipality. The results of surveys are presented next. One of them noted, in short, the public searching for news frequently, and a small dependence on journalism. The other, for professionals and related groups, revealed a shortage of diversity and the practice of "sitting journalism". Armed with this and those reviews, this work concluded that the journalism culture causes or, at least, contributes significantly to its own crises, and also can be an anti-democratic force

    Os lipomas infiltrativos diferenciam-se dos n√£o infiltrativos por invadirem tecidos adjacentes como tend√Ķes, m√ļsculos, c√°psulas articulares e ossos. Objetivou-se neste estudo relatar o primeiro caso de lipoma em car√°ter infiltrativo espont√Ęneo em um Cavia porcellus f√™mea, com idade aproximada de 8 anos e peso de 950g. Ao exame cl√≠nico observou-se uma massa subcut√Ęnea que se estendia por sobre as costelas na regi√£o toracoabdominal esquerda pesando 185g (correspondente √† 19,47% do seu peso corp√≥reo), colora√ß√£o branca/amarelada, aspecto gorduroso, macio √† palpa√ß√£o e com sinais de ader√™ncia. A pun√ß√£o aspirativa por agulha fina evidenciou esfrega√ßos n√£o corados de aspecto √ļmido com got√≠culas brilhantes que n√£o se secavam completamente ao ar, compat√≠vel com tecido gorduroso. O diagn√≥stico definitivo para lipoma foi confirmado pelo histopatol√≥gico, que revelou adip√≥citos bem diferenciados de di√Ęmetros irregulares, alguns mal circunscritos e uma √°rea com infiltra√ß√£o de adip√≥citos entre as fibras muculares. Mostrando tratar-se de uma variante infiltrativa que √© bastante raro em algumas esp√©cies. Conclui-se que o Cavia porcellus √© uma esp√©cie que pode desenvolver lipomas de car√°ter infiltrativo, devendo-se suspeitar de sua presen√ßa sempre que existir massas subcut√Ęneas bem circunscritas e aderidas

    The present study was aimed to assess the clinical changes and reproductive indices of dairy cows naturally infected with Trypanosoma vivax in a herd located in the Central Sert√£o of Cear√°, Brazil. For the study, 40 animals were selected from a herd consisting of 210 dairy cows, and subdivided into two groups: group I, consisting of 20 cows naturally infected with T. vivax, and group II, consisting of 20 uninfected cows. Data on the parameters of reproductive efficiency were evaluated using a farm database (Propad Profissional GP¬ģ), in which the individual reproductive characteristics of the animals were stored. Data collected both before and after the outbreak were compared. The cows from group I showed a sudden drop in milk production, mucosal pallor, depression, anorexia, and a significant increase in rectal temperature and decreased hematocrit during the parasitemia outbreak. These clinical signs of the disease disappeared over time. However, T. vivax was detected by polymerase chain reaction (PCR) in animals with a negative parasitological test one year after the occurrence. Comparison of the reproductive index data for cows from groups I and II before and after the outbreak showed significant differences in first postpartum estrus, service period, and intervals between deliveries. In addition, repetition of estrus and abortion were significantly associated with T. vivax infection. Analysis of the reproductive indices of cows in groups I and II suggests that T. vivax infection decreased the reproductive efficiency of the study cows.O presente estudo teve como objetivos avaliar as altera√ß√Ķes cl√≠nicas e os √≠ndices reprodutivos de vacas leiteiras infectadas naturalmente por Trypanosoma vivax em um rebanho localizado no sert√£o central do Cear√°, Brasil. No rebanho, constitu√≠do por 210 vacas leiteiras, foram selecionados 40 animais, subdivididos em dois grupos: Grupo I, composto por 20 vacas infectadas naturalmente por T. vivax e o grupo II, composto por 20 vacas n√£o infectadas. Os dados relativos aos par√Ęmetros, que indicam efici√™ncia reprodutiva dos dois grupos de animais, foram avaliados atrav√©s de um banco de dados dispon√≠vel na propriedade, por meio dos quais as caracter√≠sticas reprodutivas individuais dos animais eram armazenadas em software Propad Profissional GP¬ģ, sendo as informa√ß√Ķes obtidas, comparadas tanto no per√≠odo em que antecedeu o surto, quanto no que ocorreu ap√≥s ele. As vacas do grupo I apresentaram durante o surto alta parasitemia, queda brusca da produ√ß√£o de leite, palidez de mucosas, depress√£o, anorexia, aumento significativo da temperatura retal e redu√ß√£o do hemat√≥crito. Observou-se o desaparecimento dos sinais cl√≠nicos da enfermidade ao longo do tempo, no entanto, houve a confirma√ß√£o do diagn√≥stico de T. vivax, atrav√©s da Rea√ß√£o em Cadeia da Polimerase (PCR) em animais com exame parasitol√≥gico negativo um ano ap√≥s a ocorr√™ncia. Quando comparados os dados dos √≠ndices reprodutivos das vacas do grupo I e do grupo II, no per√≠odo em que antecedeu o surto, e no que ocorreu ap√≥s o surto, verificou-se diferen√ßas significativas para as vari√°veis: primeiro estro p√≥s-parto (PCPP/dias), per√≠odo de servi√ßo (PS-dias) e intervalo entre parto/dias (IEP). Houve associa√ß√£o significativa das vari√°veis, repeti√ß√Ķes de estro e abortamento com a infec√ß√£o por T. vivax. A an√°lise dos dados dos √≠ndices reprodutivos das vacas dos grupos I e II sugere que T. vivax diminuiu a efici√™ncia reprodutiva dos animais avaliados
