Creative Education (CE) , 2016, DOI: 10.4236/ce.2016.717249
Abstract: The teaching of mathematics involves logical and abstract reasoning that is often associated with belief, prejudices and difficulties. Therefore, students can develop an aversion to this science. This scenario may be even more complex when it involves blind students. However, creative didactic and pedagogical practices can help to deconstruct such adversities. The aim of the study was to test if eight workshops that were carried out the making four origami pieces (a small Box at it covers, a Rabbit face, and a “Bandeirinha de São João”-small flag of St. John party) could promote the construction of knowledge about geometry in 14 blind students. These students from the sixth to ninth year of elementary school are regularly enrolled of Benjamin Constant Institute, RJ, Brazil, and intend the after class. Eight workshops with 100 minutes each were conducted in September and October 2015 (n = 4) and in March and April 2016 (n = 4). Among eight paper types offered for students to make origami the kinds, we identified that the papers denominated waxed and sulfite were those who favored the realization of folds while Kraft one facilitated favored the discovery of the folds. On average, the questions concerning the geometric shapes and their elements obtained by the origami were answered correctly by eight students both for making the Box and its cover; as for the Rabbit face, and by ten students for making of small flag of St. John party. These results demonstrated the effectiveness of origami to teaching math to teenagers blind students.

Psychology (PSYCH) , 2016, DOI: 10.4236/psych.2016.712142
Abstract: Study assessed the dimensional structure of the Job Content Questionnaire’s (JCQ 2.0) main scales in two different work contexts. We evaluated two surveys among Brazilian workers, comprising 3084 health workers and 489 industrial workers. An exploratory factor analysis with oblique Geomin rotation explored the model, and subsequently, a confirmatory factor analysis assessed the factor structure and possible modifications of the model. The internal consistency of JC scales was assessed by using estimates of composite reliability and Cronbach’s alpha. The structural model was confirmed, with a good fit in the two studies, despite low factors’ loads for some items of “decision authority” and “psychological job demands”. We concluded that the JCQ dimensional structure corresponded to its theoretical framework in the two work contexts analyzed.

PLOS ONE , 2012, DOI: 10.1371/journal.pone.0052450
Abstract: Delta-like 4 (Dll4) is a ligand of the Notch pathway family which has been widely studied in the context of tumor angiogenesis, its blockade shown to result in non-productive angiogenesis and halted tumor growth. As Dll4 inhibitors enter the clinic, there is an emerging need to understand their side effects, namely the systemic consequences of Dll4:Notch blockade in tissues other than tumors. The present study focused on the effects of systemic anti-Dll4 targeting in the bone marrow (BM) microenvironment. Here we show that Dll4 blockade with monoclonal antibodies perturbs the BM vascular niche of sub-lethally irradiated mice, resulting in increased CD31+, VE-Cadherin+ and c-kit+ vessel density, and also increased megakaryocytes, whereas CD105+, VEGFR3+, SMA+ and lectin+ vessel density remained unaltered. We investigated also the expression of angiocrine genes upon Dll4 treatment in vivo, and demonstrate that IGFbp2, IGFbp3, Angpt2, Dll4, DHH and VEGF-A are upregulated, while FGF1 and CSF2 are reduced. In vitro treatment of endothelial cells with anti-Dll4 reduced Akt phosphorylation while maintaining similar levels of Erk 1/2 phosphorylation. Besides its effects in the BM vascular niche, anti-Dll4 treatment perturbed hematopoiesis, as evidenced by increased myeloid (CD11b+), decreased B (B220+) and T (CD3+) lymphoid BM content of treated mice, with a corresponding increase in myeloid circulating cells. Moreover, anti-Dll4 treatment also increased the number of CFU-M and -G colonies in methylcellulose assays, independently of Notch1. Finally, anti-Dll4 treatment of donor BM improved the hematopoietic recovery of lethally irradiated recipients in a transplant setting. Together, our data reveals the hematopoietic (BM) effects of systemic anti-Dll4 treatment result from qualitative vascular changes and also direct hematopoietic cell modulation, which may be favorable in a transplant setting.

Abstract: This study describes the phytochemical profile and antioxidant activity of an extract from the leaves of Pouteria caimito (Sapotaceae). The extract in ethanol was obtained by maceration at room temperature and subjected to the liquid-liquid partition to obtain fractions in hexane and ethyl acetate. Steroids, triterpenes, saponins, alkaloids and flavonoids were identified by the phytochemical prospection of extracts and fractions from the leaves. The analysis of the ethyl acetate fraction by UPLC-QTOF-MS allowed us to identify eight triterpenes, namely, euscaphic acid (1), hyptadienic acid (2), betulinic acid (3), oleanolic acid (4), ursolic acid (5), 3β-(O-p-coumaroyl)- alphitolic acid (6), 3β-(O-p-coumaroyl)-maslinic acid (7) and 3β-(O-p-coumaroyl)-2-hydroxy-urs-12-en-28-oic acid (8). The ethanol extract and ethyl acetate fraction presented total phenolic contents of 10.6 ± 0.1 and 11.4 ± 0.3 mg GAE g-1, respectively, and considerable antioxidant activity in the DPPH assay with EC50 values of 299.4 ± 1.5 and 391.8 ± 0.9 μg·ml-1, respectively.

Araújo, Tania Maria de;Carvalho, Fernando Martins;
Educa??o & Sociedade , 2009, DOI: 10.1590/S0101-73302009000200007
Abstract: teacher's work and health conditions were analyzed on the basis of results coming from eight epidemiological studies carried out in the state of bahia, brazil. the studies among teachers, performed from 1996 to 2007, have determined the prevalence of the three main groups of health complaints (voice problems, musculoskeletal problems, and mental health problems) and tried to associate them to characteristics of teacher's work organization. the studies revealed important contributions of the aspects related to school work environment and teachers' work organization to the occurrence of the negative health effects investigated. inspite of the exploratory approach of these studies, the joint analysis of data showed that teachers in high strain jobs also presented the highest prevalence rates of poor health effects. these results support the necessity of policies that encompass prevention and attention to teacher's health.

Abstract: O projeto de pesquisa Perturba es do espectro de autismo – perfil do alunado e interven o educacional na rede pública do Distrito Federal integra o Programa de Apoio à Educa o Especial, iniciativa da Secretaria de Educa o Especial, em parceria com a Capes, que vem alocando investimentos técnicos e financeiros para apoiar e incentivar a pesquisa em educa o especial. Como tal, o projeto volta-se à realiza o de investiga es e estudos acerca da inclus o de pessoas com perturba es do espectro do autismo e à capacita o, em nível de pós-gradua o lato e stricto sensu de profissionais que atuam na educa o especial. Pretende ser um, dentre os múltiplos instrumentos e a es, que possibilitem o atendimento das atuais prerrogativas educacionais que regem a Política Nacional de Educa o: a inclus o escolar de todos os alunos. A literatura aponta que ainda há um grande contingente de pessoas com e sem deficiência, sem escolariza o, excluído do processo educacional e do atendimento educacional especializado, apesar dos esfor os até ent o envidados nesse sentido. O atendimento educacional especializado aos alunos com deficiência vinha sendo desenvolvido, prioritariamente, em classes e escolas especiais, em salas de recursos, por meio de servi os de itinerancia, dentre outras modalidades, situa o que a política hodierna pretende reverter, direcionando esfor os no sentido de oferecer insumos técnicos e financeiros para criar condi es de sustentabilidade a esse atendimento na classe comum, como preconiza o princípio da inclus o escolar.

Memórias do Instituto Oswaldo Cruz , 2001,
Abstract: During the period from 1987 to 1998, 13 cases of human sporotrichosis were recorded at the Research Center Evandro Chagas Hospital (CPqHEC) in Rio de Janeiro. Two of these patients related scratch by a sick cat. During the subsequent period from July 1998 to July 2000, 66 human, 117 cats and 7 dogs with sporotrichosis were diagnosed at the CPqHEC. Fifty-two humans (78.8%) reported contact with cats with sporotrichosis, and 31 (47%) of them reporting a history of a scratch or bite. This epidemic, unprecedented in the literature, involving cats, dogs and human beings may have started insidiously before 1998.
