We reviewed the occurrences and distributional patterns of migratory species of birds in Brazil. A species was classified as migratory when at least part of its population performs cyclical, seasonal movements with high fidelity to its breeding grounds. Of the 1,919 species of birds recorded in Brazil, 198 (10.3%) are migratory. Of these, 127 (64%) were classified as Migratory and 71 (36%) as Partially Migratory. A few species (83; 4.3%) were classified as Vagrant and eight (0,4%) species could not be defined due to limited information available, or due to conflicting data.

BackgroundAcute lymphoblastic leukemia is the most common malignant cancer in childhood. The signs and symptoms of childhood cancer are difficult to recognize, as it is not the first diagnosis to be considered for nonspecific complaints, leading to potential uncertainty in diagnosis. The aim of this study was to perform proteomic analysis of serum from pediatric patients with B-cell acute lymphoblastic leukemia (B-ALL) to identify candidate biomarker proteins, for use in early diagnosis and evaluation of treatment.MethodsSerum samples were obtained from ten patients at the time of diagnosis (B-ALL group) and after induction therapy (AIT group). Sera from healthy children were used as controls (Control group). The samples were subjected to immunodepletion, affinity chromatography with α-d-galactose-binding lectin (from Artocarpus incisa seeds) immobilized on a SepharoseTM 4B gel, concentration, and digestion for subsequent analysis with nano-UPLC tandem nano-ESI-MSE. The program ExpressionE was used to quantify differences in protein expression between groups.ResultsA total of 96 proteins were identified. Leucine-rich alpha-2-glycoprotein 1 (LRG1), Clusterin (CLU), thrombin (F2), heparin cofactor II (SERPIND1), alpha-2-macroglobulin (A2M), alpha-2-antiplasmin (SERPINF2), Alpha-1 antitrypsin (SERPINA1), Complement factor B (CFB) and Complement C3 (C3) were identified as candidate biomarkers for early diagnosis of B-ALL, as they were upregulated in the B-ALL group relative to the control and AIT groups. Expression levels of the candidate biomarkers did not differ significantly between the AIT and control groups, providing further evidence that the candidate biomarkers are present only in the disease state, as all patients achieved complete remission after treatment.ConclusionA panel of protein biomarker candidates has been developed for pre-diagnosis of B-ALL and also provided information that would indicate a favorable response to treatment after induction therapy.

RESUMOAs ações antrópicas têm fomentado a presença de diversos microcontaminantes nos corpos d' água. Desses, mais recentemente, os fármacos e os desreguladores endócrinos têm chamado a atenção da comunidade científica acerca da crescente exposição dos corpos d' água a esses fármacos e desreguladores.As fontes de contaminação englobam produtos de limpeza e higiene pessoal, fármacos de diversas classes, hormônios naturais e seus subprodutos, além de diversas substâncias aplicadas na produção de plásticos e resinas, presentes nos esgotos sanitários, lixiviados de aterro e efluentes industriais. Nessa perspectiva, o artigo presta-se a compilar os dados de ocorrências desses microcontaminantes em águas brasileiras naturais e tratadas assim, como a discutir a eficiência de diferentes técnicas de tratamento de água na remoção de tais contaminantes.

Although canola, (Brassica napus L.), is considered a self-pollinating crop, researchers have indicated that crop productivity increases as a result of honey bee Apis mellifera L. pollination. Given this crop's growing importance in Rio Grande do Sul State, Brazil, this work evaluated the increase in pod and seed productivity with respect to interactions with anthophilous insects and manual pollination tests. The visiting frequency of A. mellifera was correlated with the crop's blooming progression, and productivity comparisons were made between plants visited by insects, manually pollinated plants (geitonogamy and xenogamy) and plants without pollination induction. Pod set and seed production per plant were determined for each treatment. Among the 8,624 recorded flower-visiting insects, Hymenoptera representatives were the most prevalent (92.3%), among which 99.8% were A. mellifera. The correlation between these bees and blooming progression was positive (r = 0.87; p = 0.002). Pollination induction increased seed productivity from 28.4% (autogamy) to 50.4% with insect visitations, as well as to 48.7 (geitonogamy) and to 55.1% (xenogamy) through manual pollination. Key words: flower-visiting insects, blooming, canola productivity Abelhas melíferas na polinização de canola no Sul do Brasil RESUMO: A canola (Brassica napus L.) é considerada autocompatível, embora pesquisadores indiquem aumento na produtividade da cultura resultante da polinização efetuada por Apis mellifera L.. Considerando-se a crescente importância dessa cultura no Rio Grande do Sul, avaliou-se o incremento da produtividade de síliquas e sementes a partir de interações com insetos antófilos e com testes de polinização manual. A freqüência de visitas de A. mellifera foi relacionada com o desenvolvimento da floração da cultura e a produtividade foi comparada entre plantas visitadas por insetos, polinizadas manualmente (geitonogamia e xenogamia) e com ausência de indução de polinização. Em cada tratamento avaliou-se a produtividade de síliquas e de sementes formadas por planta. Dentre os 8.624 insetos visitantes florais registrados destacaram-se representantes de Hymenoptera (92,3%), dos quais 99,8% eram A. mellifera. A relação entre essas abelhas e o curso da floração foi positiva (r = 0,87; p = 0,002). A indução de polinização elevou a produtividade de sementes de 28,3% (autogamia) para 50,4% com livre visita de insetos e com polinização manual, respectivamente, para 48,7 (geitonogamia) e 55,1% (xenogamia).

ResumoFoi avaliada a sobrecarga de familiares cuidadores de pacientes psiquiátricos e sua relação com as habilidades sociais e assertividade. Participaram 53 familiares, atendidos em um CAPS tipo I. Utilizou-se a Escala de Sobrecarga BI, o Inventário de Habilidades Sociais IHS-Del-Prette, a Escala de Assertividade RAS e um Questionário Sociodemográfico e Clínico. Os resultados mostraram que os familiares com maior grau de inibição e timidez (RAS) apresentaram escores significativamente mais elevados de sobrecarga. A análise de regressão múltipla mostrou que a timidez foi o principal fator preditivo da sobrecarga. Não foi encontrada relação da sobrecarga com os escores do IHS-Del-Prette. Os dados apontam para a necessidade de implementar ações psicoeducacionais nos serviços de saúde mental, envolvendo o treinamento de assertividade dos familiares cuidadores, contribuindo, assim, para um melhor relacionamento com os pacientes e uma busca mais eficiente de suporte social, para o desempenho do papel de cuidador com menor sobrecarga.

Burden in family caregivers of psychiatric patients: relation with assertive behavior AbstractThis research evaluated the family caregivers' burden regarding the care of psychiatric patients and its relation to social skills and assertiveness. The sample was composed of 53 family caregivers of patients who were treated in a community mental health service (CAPS type I). They were interviewed with the application of the Burden Scale BI, the Social Skills Inventory IHS-Del-Prette, the Assertiveness Scale RAS, and a Sociodemographic and Clinical Questionnaire. Results showed that family caregivers presenting higher degree of inhibition and shyness (RAS) had significantly higher burden scores. Multiple regression analysis showed that shyness was the main predictive factor for burden. No relation was found between burden and IHS-DelPrette scores. Data indicated the need to implement psychoeducational programs in mental health services in order to increase caregivers' assertive behavior, so that they could develop a better relationship with patients and a more efficient search for social support, contributing to decrease burden.
