Family Health Strategy and More Doctors Program in Rural Area of Porto Velho, Brazil: A Qualitative Analysis under the Nurse’s Perspective

The Family Health Strategy (FHS) together with the implementation of the More Doctors Program (MDP) has an effective contribution to the strengthening of Primary Health Care (PHC) and the consolidation of the Unified Health System (SUS), which has intended to meet the health needs of the population in need of care less complex. Thus, this study aims to analyze the Family Health Strategy and the Program More Doctors implanted in the Rural Municipality of Porto Velho, Rondônia, from the perspective of nurses. This is a qualitative research, descriptive exploratory performed in the field, based on the assessment the perspective of nurses working in the FHS, which are favored by the MDP. The data collection was carried out through a questionnaire,Primary Care Assessment Tool (PCA Tool), in its version validated in Brazil entitled PCA Tool- Brazil (BRAZIL, 2010). This instrument is widely used by national research that evaluates the quality of primary care. For the construction of the database was used Microsoft Word software. For qualitative data, the collection was carried out through interviews recorded by a script containing open questions. The response were discussed based on the content analysis technique proposed by Bardin (2011). The results achieved indicate that the MDM enabled the structuring of teams that were incomplete in the rural area of the town, however presents numerous challenges in the organization of the work process and the understanding of program objectives

Direct reprogramming of adult human somatic stem cells into functional neurons using Sox2, Ascl1, and Neurog2

Reprogramming of somatic cells into induced pluripotent stem cells (iPS) or directly into cells from a different lineage, including neurons, has revolutionized research in regenerative medicine in recent years. Mesenchymal stem cells are good candidates for lineage reprogramming and autologous transplantation, since they can be easily isolated from accessible sources in adult humans, such as bone marrow and dental tissues. Here, we demonstrate that expression of the transcription factors (TFs) SRY (sex determining region Y)-box 2 (Sox2), Mammalian achaete-scute homolog 1 (Ascl1), or Neurogenin 2 (Neurog2) is sufficient for reprogramming human umbilical cord mesenchymal stem cells (hUCMSC) into induced neurons (iNs). Furthermore, the combination of Sox2/Ascl1 or Sox2/Neurog2 is sufficient to reprogram up to 50% of transfected hUCMSCs into iNs showing electrical properties of mature neurons and establishing synaptic contacts with co-culture primary neurons. Finally, we show evidence supporting the notion that different combinations of TFs (Sox2/Ascl1 and Sox2/Neurog2) may induce multiple and overlapping neuronal phenotypes in lineage-reprogrammed iNs, suggesting that neuronal fate is determined by a combination of signals involving the TFs used for reprogramming but also the internal state of the converted cell. Altogether, the data presented here contribute to the advancement of techniques aiming at obtaining specific neuronal phenotypes from lineage-converted human somatic cells to treat neurological disorders

The Genome of Anopheles darlingi, the main neotropical Malaria vector

Anopheles darlingi is the principal neotropical malaria vector, responsible for more than a million cases of malaria per year on the American continent. Anopheles darlingi diverged from the African and Asian malaria vectors ∼100 million years ago (mya) and successfully adapted to the New World environment. Here we present an annotated reference A. darlingi genome, sequenced from a wild population of males and females collected in the Brazilian Amazon. A total of 10 481 predicted protein-coding genes were annotated, 72% of which have their closest counterpart in Anopheles gambiae and 21% have highest similarity with other mosquito species. In spite of a long period of divergent evolution, conserved gene synteny was observed between A. darlingi and A. gambiae. More than 10 million single nucleotide polymorphisms and short indels with potential use as genetic markers were identified. Transposable elements correspond to 2.3% of the A. darlingi genome. Genes associated with hematophagy, immunity and insecticide resistance, directly involved in vector–human and vector–parasite interactions, were identified and discussed. This study represents the first effort to sequence the genome of a neotropical malaria vector, and opens a new window through which we can contemplate the evolutionary history of anopheline mosquitoes. It also provides valuable information that may lead to novel strategies to reduce malaria transmission on the South American continent. The A. darlingi genome is accessible a

De que contexto se fala? Análise de livros didáticos de Química para o ensino médio

Esta comunicação apresenta a análise de livros didáticos de Química para o ensino médio, indicados no PNLD 2012 (Brasil, 2011), em relação a contextualização dos conteúdos químicos, como resultado de atividade desenvolvida com bolsistas do Programa Institucional de Bolsa de Iniciação a Docência do curso de Licenciatura em Química da Universidade Federal da Bahia (PIBID/UFBA), contando com a participação dos estudantes matriculados na disciplina Ensino de Química no Contexto, no semestre 2011.2. Foram consideradas três categorias de análise, baseadas em Silva (2007) e os resultados apontaram que dos livros analisados, três apresentam a contextualização como exemplificação e/ou informação do cotidiano, um apresenta contextualização relacionada ao movimento CTS e um outro aproxima-se também desse tipo de contextualização, embora tenha como foco a construção do conhecimento

Genome-wide association analyses of physical activity and sedentary behavior provide insights into underlying mechanisms and roles in disease prevention

Although physical activity and sedentary behavior are moderately heritable, little is known about the mechanisms that influence these traits. Combining data for up to 703,901 individuals from 51 studies in a multi-ancestry meta-analysis of genome-wide association studies yields 99 loci that associate with self-reported moderate-to-vigorous intensity physical activity during leisure time (MVPA), leisure screen time (LST) and/or sedentary behavior at work. Loci associated with LST are enriched for genes whose expression in skeletal muscle is altered by resistance training. A missense variant in ACTN3 makes the alpha-actinin-3 filaments more flexible, resulting in lower maximal force in isolated type IIA muscle fibers, and possibly protection from exercise-induced muscle damage. Finally, Mendelian randomization analyses show that beneficial effects of lower LST and higher MVPA on several risk factors and diseases are mediated or confounded by body mass index (BMI). Our results provide insights into physical activity mechanisms and its role in disease prevention. Multi-ancestry meta-analyses of genome-wide association studies for self-reported physical activity during leisure time, leisure screen time, sedentary commuting and sedentary behavior at work identify 99 loci associated with at least one of these traits
