Diseño de una estrategia pedagógica basada en el aprendizaje significativo para la formación de las madres comunitarias del barrio el campin centro zonal Yariguies Barrancabermeja

El diseño de una estrategia pedagógica para las madres comunitarias del Centro Zonal Yariguies en Barrancabermeja pretende Fortalecer los procesos de capacitación que se adelantan en el ICBF en especial para las 15 madres comunitarias encargadas de los hogares pertenecientes a al barrio el Campín, para que estos se realicen de una forma activa y participativa que tenga en cuenta los procesos de aprendizaje como adultos y que permita disminuir los índices de desmotivación para las capacitaciones y la aplicación de sus conocimientos en su que hacer pedagógico. Por ello la estrategia esta basada en el aprendizaje significativo, en especial de contenidos procedimentales “saber hacer” y en el proceso de aprendizaje de adultos teniendo en cuenta la caracterización de la población a la cual va dirigida.

Change in expression of miR-let7c, miR-100, and miR-218 from high grade localized prostate cancer to metastasis

Objective: MicroRNAs (miRNAs) are small noncoding regulatory RNAs (19-25 nucleotides) that play a major role in regulation of gene expression. They are responsible for the control of fundamental cellular processes that has been reported to be involved in human tumorigenesis. The characterization of miRNA profiles in human tumors is crucial for the understanding of carcinogenesis processes, finding of new tumor markers, and discovering of specific targets for the development of innovative therapies. The aim of this study is to find miRNAs involved in prostate cancer progression comparing the profile of miRNA expressed by localized high grade carcinoma and bone metastasis. Material and methods: Two groups of tumors where submitted to analyses. The first is characterized by 18 patients who underwent radical prostatectomy for treatment of localized high grade prostate carcinoma (PC) with mean Gleason score 8.6, all staged pT3. The second group is composed of 4 patients with metastatic, androgen-independent prostate carcinoma, and 2 PC cell lines. LNCaP derived from a metastatic PC to a lymph node, and another derived from an obstructive, androgen-independent PC (PcBRA1). Expression analysis of 14 miRNAs was carried out using quantitative RT-PCR. Results: miR-let7c, miR-100, and miR-218 were significantly overexpressed by all localized high GS, pT3 PC in comparison with metastatic carcinoma. (35.065 vs. 0.996 P < 0.001), (55.550 vs. 8.314, P = 0.010), and (33.549 vs. 2.748, P = 0.001), respectively. Conclusion: We hypothesize that miR-let7c, miR-100, and miR-218 may be involved in the process of metastasization of PC, and their role as controllers of the expression of RAS, c-myc, Laminin 5 beta 3, THAP2, SMARCA5, and BAZ2A should be matter of additional studies.

The BRCA2 372 HH genotype is associated with risk of breast cancer in Australian women under age 60 years

The BRCA2 N372H nonconservative amino acid substitution polymorphism appears to affect fetal survival in a sex-dependent manner, and the HH genotype was found to be associated with a 1.3-fold risk of breast cancer from pooling five case-control studies of Northern European women. We investigated whether the BR 2 N372H polymorphism was associated with breast cancer in Australian women using a population-based case-control design. The BRCA2 372 genotype was determined in 1397 cases under the age of 60 years at diagnosis of a first primary breast cancer and in 775 population-sampled controls frequency matched for age. Case-control analyses and comparisons of genotype distributions were conducted using logistic regression. All of the statistical tests were two-tailed. The HH genotype was independent of age and family history of breast cancer within cases and controls, and was more common in cases (9.2% versus 6.5%). It was associated with an increased risk of breast cancer, 1.47-fold unadjusted (95% confidence interval, 1.05-2.07; P = 0.02), and 1.42-fold (95% confidence interval, 1.00-2.02; P = 0.05) after adjusting for measured risk factors. This effect was still evident after excluding women with any non-Caucasian ancestry or the 33 cases known to have inherited a mutation in BRCA1 or BRCA2, and would explain similar to3% of breast cancer. The BRCA2 N372H polymorphism appears to be associated with a modest recessively inherited risk of breast cancer in Australian women. This result is consistent with the findings for Northern European women.

Constituição do Medo e Fim de 218.660 Empregos

Se uns têm medo da Constituição lusa actual, uma das mais humanistas do mundo, outros querem uma “Constituição do Medo”. Dizíamos no último artigo, um dia antes de Nª Srª da Assunção (ainda é feriado!), que o Art. 1º da Constituição, “República Portuguesa”, diz: “Portugal é uma República soberana, baseada na dignidade da pessoa humana e na vontade popular e empenhada na construção de uma sociedade livre, justa e solidária”. § If some are afraid of the current Portuguese Constitution, one of the humanists of the world, others want a 'Constitution of Fear. "We said in the last article, the day before Our Lady of the Assumption (it's still holiday!), That Article 1 of the Constitution, "Portugal", he says. "Portugal is a sovereign Republic, based on human dignity and popular will and committed to building a free society, justice and solidarity ".

Após discutir o tipo de fonte que tem sido privilegiado na maioria dos estudos sobre o tema, analiso qual tipo de alforria foi mais relevante em Rio de Contas para entender os sentidos que escravos e senhores lhe atribuíram.

IDENTIFICATION OF Leishmania infantum IN PUERTO IGUAZÚ, MISIONES, ARGENTINA

 The emergence of zoonotic visceral leishmaniasis (ZVL) in Latin America is a growing public health problem. The urbanization of ZVL has been observed in different countries around the world, and there are a growing number of reports drawing attention to the emergence of this infection in new locations, as well as its increase in previously established areas of endemicity. In the city of Posadas, Misiones province, Northeastern Argentina, the transmission of ZVL associated with canines and Lutzomyia longipalpis was first reported in 2006. In the city of Puerto Iguazú, also in Misiones province, the first human case of ZVL was reported in February 2014. From 209 surveyed dogs, 15 (7.17%) were identified as positive by serological and/or parasitological methods. Amplification was observed in 14 samples and in all cases the species implicated was Leishmania infantum. To the authors’ knowledge, this is the first molecular characterization of L. infantum from dogs in this area.

COMPORTAMENTO DE LEVEDURAS DO GÊNERO CANDIDA"IN VITRO" A ANTIFÚNGICOS

Estudou-se o comportamento de leveduras do gênero Candida a antifungicos, pela determinação da Concentração Inibitória Mínima (CIM) e da Concentração Fungicida Mínima (CFM) "in vitro"de 30 cepas de Candida frente aos antifungicos: miconazol, cetoconazol e anfotericina B. Empregou-se o método de diluição em meio líquido e os antifungicos foram diluídos visando proporcionar concentrações a partir de 0,06 a 128 μg/mL. O inóculo foi padronizado ajustando-se a suspensão para conter 1X 106 ufc/mL. A concentração para a qual houve maior convergência de cepas foi de 1 μg/mL (26,5%) para anfotericina B. Para miconazol foi de 16 μg/mL (26,0%) e para cetoconazol 32 μg/mL (23,0%). Os valores de CFM foram de 2 μg/mL (23,5%) para anfotericina B, de 16 e 64 μg/mL (26,5%) para miconazol e 32 e 64 μg/mL (30,0%) para cetoconazol. Este imidazólico mostrou os valores de CIM e CFM mais elevados atingindo até 128 μg/mL em algumas espécies. As espécies de Candida mostraram-se mais sensíveis à Anfotericina B, quando comparadas em relação aos antifungicos testados. Sobre o desempenho das espécies de Candida, melhor padrão de comportamento foi verificado para C. albicans com níveis mais baixos de sensibilidade.

ANÁLISE DE CRESCIMENTO DE MUDAS DE JACAREÚBA (Calophyllum angulare A. C. SMITH - GUTTIFERAE) CULTIVADAS EM CONDIÇÕES DE VIVEIRO.

O presente trabalho, conduzido no viveiro da Reserva Florestal Adolfo Ducke, Amazonas, Brasil, teve como objetivo comparar quatro níveis de sombreamento no crescimento de mudas de jacareúba (Calophyllum angulare). Foram utilizados os níveis de sombreamento 30,50 e 70%, obtidos com telas de poliolefinas de cor preta, e o nível 0% a pleno sol. A análise de crescimento foi feita imediatamente após a transferência das mudas para os canteiros e mensalmente durante 5 meses. Foram obtidos os seguintes resultados: a) Os maiores valores de altura; diâmetro do colo-e área foliar foram obtidos nas mudas cultivadas sob 70% de sombreamento aos 150 dias de permanência no viveiro; b)Ocorreu uma tendência de decréscimo nos valores de taxa de crescimento relativo foliar e de razão de área foliar em decorrência do período de permanência das mudas no viveiro; c) A taxa de crescimento relativo foliar não foi influenciada pelos níveis de sombreamento; d) As mudas cultivadas sob 70% apresentaram valores de taxa de crescimento relativo da parte aérea que indicam uma melhor adaptação a essa condição; com relação a taxa de crescimento relativo das raízes, os níveis de sombreamento mais favoráveis foram 0 e 50%; e) O efeito da aclimatação sobre as mudas cultivadas sob 70%, provocou uma diminuição temporária nas taxas de crescimento relativo da parte aérea c crescimento relativo total, entre os períodos de 30 a 60 dias.

Physical activity attenuates the influence of FTO variants on obesity risk: a meta-analysis of 218,166 adults and 19,268 children.

BACKGROUND: The FTO gene harbors the strongest known susceptibility locus for obesity. While many individual studies have suggested that physical activity (PA) may attenuate the effect of FTO on obesity risk, other studies have not been able to confirm this interaction. To confirm or refute unambiguously whether PA attenuates the association of FTO with obesity risk, we meta-analyzed data from 45 studies of adults (n = 218,166) and nine studies of children and adolescents (n = 19,268). METHODS AND FINDINGS: All studies identified to have data on the FTO rs9939609 variant (or any proxy [r(2)>0.8]) and PA were invited to participate, regardless of ethnicity or age of the participants. PA was standardized by categorizing it into a dichotomous variable (physically inactive versus active) in each study. Overall, 25% of adults and 13% of children were categorized as inactive. Interaction analyses were performed within each study by including the FTO×PA interaction term in an additive model, adjusting for age and sex. Subsequently, random effects meta-analysis was used to pool the interaction terms. In adults, the minor (A-) allele of rs9939609 increased the odds of obesity by 1.23-fold/allele (95% CI 1.20-1.26), but PA attenuated this effect (p(interaction)  = 0.001). More specifically, the minor allele of rs9939609 increased the odds of obesity less in the physically active group (odds ratio  = 1.22/allele, 95% CI 1.19-1.25) than in the inactive group (odds ratio  = 1.30/allele, 95% CI 1.24-1.36). No such interaction was found in children and adolescents. CONCLUSIONS: The association of the FTO risk allele with the odds of obesity is attenuated by 27% in physically active adults, highlighting the importance of PA in particular in those genetically predisposed to obesity.
