    This study describes the composition and structure of the benthic community associated with bryophytes in a first-order stream, located in a biological reserve of the Atlantic Forest, during two seasons. During three months of the dry season of 2007 and three months of the rainy season of 2008, samples of bryophytes attached to stones were collected randomly, along a 100 m stream reach. The structure of the community was analyzed through the mean density of individuals, Shannon's diversity index, Pielou's evenness, family richness, dominance index, and the percentage of Ephemeroptera, Plecoptera and Trichoptera (% EPT). Chironomidae larvae were dominant in the two periods of study, followed by Ceratopogonidae in the rainy season, and Naididae in the dry season. The orders EPT contributed 14 families. The results showed that bryophytes constitute suitable habitat which is able to shelter an abundant and diversified benthic fauna in a small extension of the stream. This habitat provides refuge during spates, and thus minimizes downstream transport of the macroinvertebrate fauna.

Utilizou-se tcnica de completamento de frases para a coleta de dados e anlise de contedo para estabelecimento de categorias temticas.

Resultados: o material foi classificado e agrupado em trs categorias temticas: a primeira, Quando os olhares se deparam com mudanas; a segundo, A famlia no con(viver) da DPP e a ltima, Profissionais x Instituio: repercusses do (des)compromisso. Concluses: o cuidado com a mulher com quadro de DPP assumido por membros da famlia. A famlia se v envolvida num acmulo de emoes, marcados por sentimentos de medo, tristeza, desespero e pnico. Os servios de sade devem estar organizados para oferecer atendimento integral a todos os agravos que os indivduos apresentarem. Torna-se imperiosa a necessidade de sensibilizar e qualificar profissionais de sade para a importncia do fenmeno que se constitui a DPP

    Relato de caso: suspeita clínica e diagnóstico de síndrome nefrótica em paciente adulto em pronto-socorro

    A Síndrome Nefrótica é caracterizada pela presença de proteinúria maciça (maior que 3.5g/1,73m² em 24 horas), hipoalbuminemia (<3g/dL) e edema periférico, podendo ser acompanhada também por hiperlipidemia e hipercoagulabilidade. Pode ser decorrente de condições primárias ou associada a doenças sistêmicas. Em pacientes adultos, cerca de 30% apresentam doenças sistêmicas concomitantes; o restante está relacionado a alterações primárias dos rins. A evolução dessa síndrome depende de qual glomerulopatia está envolvida, o que determina a possibilidade de resposta ao tratamento e o risco de evolução para doença renal crônica (DRC).

    Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

    Foram coletados oito sistemas reprodutores de fêmeas de gambás (Didelphis sp). Destes cinco, foram destinados ao estudo macroscópico e três ao estudo microscópico. Estes animais encontravam-se fixados no Departamento de Anatomia da UNIfeob, em formaldeído a 10%, provenientes do Criatório Científico de Araçatuba (IBAMA). Para análise macroscópica, os sistemas reprodutores foram retirados, guardando-se as devidas posições "in situ" e foi realizada a documentação fotográfica para resultados macroscópicos. Para o estudo microscópico, o sistema reprodutor foi processado rotineiramente pela técnica de inclusão em Paraplast e cortadas em micrótomo, com espessura média de 5 mm, e os cortes foram corados em HE, Azul de Toluidina, Picrosírius, PAS e tricromo de Masson16, 17. O sistema reprodutor feminino do gambá era composto por dois ovários, útero duplo, duas vaginas laterais e entre estas um canal pseudovaginal, estas três estruturas se unem formando o seio urogenital encerrando em um "monte" púbico ou tubérculo genital, formando uma abertura comum interna ao ânus e a vulva, chamada de pseudocloaca ou seio urogenital. Microscopicamente os ovários eram funcionais com folículos mono e poliovulares. A tuba uterina era característica, revestida por epitélio prismático ciliado. Os cornos uterinos apresentaram epitélio de revestimento prismático ciliado. O seio urogenital apresentou três estruturas tubulares. A vulva apresentou as mesmas características da peleEight reproductive systems of opossum females of had been collected (Didelphis sp). Five, had been destined to macrocospic study and three to the microscopical study. These animals were died and fixeded in the Department of Anatomy of the UNIfeob, with formaldehyde 10% from Araçatuba scientific creator - IBAMA. For macrocospic analysis, the reproductive systems had been removed, keeping to its positions "in situ" and were carried through the photographic documentation for macrocospic results. For the microscopical study, the reproductive system was processed routinely by the technique of inclusion in similar of paraffin and cut with 5µm thickness, and the cuts had been stained in HE, Toluidin blue, Picrosirius, PAS (periodic acid Shiff reaction) and tricromo de Masson16, 17. The feminine reproductive system of the opossum was compose for two ovaries, double uterus, two lateral vagins and between these a pseudovaginal canal, these three structures if they join forming the urogenital sinus locking up in a "pubic mount" or genital tubercle, forming an internal common opening to the anus and vulva, call of pseudocloaca or urogenital sinus. Microscopically the ovarios were functional with mono and poliovulares follicles. The uterine tube was characteristic, coated for ciliad prismatic epithelium. The uterine horns had presented epithelium of ciliad prismatic covering. The urogenital sinus presented three tubular structures. Vulva presented the same characteristics of the ski
