Presença Americana na Educação Física Brasileira: padrões culturais na imprensa periódica (1932-1950)
Esta pesquisa procura compreender a circulação e as apropriações do americanismo, movimento político-cultural que nasce a partir da hegemonia interna desenvolvida pelos Estados Unidos da América e que se torna modelo de modernidade para outros países. Utiliza, como referencial teórico-metodológico, o repertório da Nova História Cultural, bem como o modelo indiciário fundamentado na microhistória italiana. Como fonte documental, faz uso das publicações periódicas da Educação Física que circularam no Brasil na primeira metade do século XX. A análise do corpus documental indica que, a partir de 1932, com a publicação dos primeiros periódicos da Educação Física, é observável a circulação e a apropriação das representações sobre o americanismo, cujos traços culturais permeiam as práticas esportivas e a forma escolar da Educação Física. Mais que isso, os indícios apontam para uma estratégia de divulgação do modo de vida americano, síntese de eficácia e modernidade, especialmente nas revistas publicadas por editoras comerciais que fazem mais referências aos Estados Unidos que as publicações de editoras autárquicas, utilizando para isso, algumas vezes, o movimento pan-americanista, havendo ainda a circulação de publicidade de produtos e bens de consumo produzidos por indústrias americanas. Podemos constatar ainda que, embora não possa ser caracterizada como um locus de difusão do americanismo, a Associação Cristã de Moços contribuiu com essa circulação e consequente apropriação do americanismo pelo fato de ter sido trazida para a América do Sul por americanos que, em suas atividades, trouxeram imagens da cultura americana como o ápice da modernidade
Induced Chern-Simons modified gravity at finite temperature
We calculate the linearized four-dimensional gravitational Chern-Simons term
at the finite temperature, show its finiteness and explicitly demonstrate that
its transversal part matches the known result for the chiral vortical
conductivity.Comment: 14 pages, version accepted to JHE
Neutron Transfer reactions induced by 8Li on 9Be
Angular distributions for the elastic scattering of 8Li on 9Be and the
neutron transfer reactions 9Be(8Li,7Li)10Be and 9Be(8Li,9Li)8Be have been
measured with a 27 MeV 8Li radioactive nuclear beam. Spectroscopic factors for
8Li|n=9Li and 7Li|n=8Li bound systems were obtained from the comparison between
the experimental differential cross section and finite-range DWBA calculations
with the code FRESCO. The spectroscopic factors obtained are compared to shell
model calculations and to other experimental values from (d,p) reactions. Using
the present values for the spectroscopic factor, cross sections for the direct
neutron-capture reactions 7Li(n,g)8Li and 8Li(n,g)9Li were calculated in the
framework of a potential model.Comment: 24 pages, 8 Figures, submitted as regular article to PR

Morpho/Proteomic Comparative between High Grade Pleomorphic Sarcoma and Metastasis Diagnosed in an Old Captive Common Hippo
Old age is a risk factor for cancer development in humans and animals, and studies have shown that tumors in animals are acceptable models for studying human cancers, considering the similarities between their factors. This work was conducted in a 53-year-old captive female common hippo (Hippopotamus amphibious) with a left leg tumor and metastatic mass. Histopathological and immunohistochemical analyses were carried out with a final diagnosis of a high grade pleomorphic sarcoma. A proteomic study using mass spectrometry was added in order to identify further aspects of the primary tumor and metastasis which could improve our understanding, and each tissue showed a proteomic profile indicative of its pathologic state with significant differences between healthy tissue, primary and metastatic tumors. Low levels of beta-actin in primary tumors were identified, and this may be associated with a possible consequence of cytoskeleton dynamic modification. In metastatic tissue, these dynamics may be affected by the presence of HSP chaperone 60.FAPESP: 2012/02514-9Univ Fed Sao Paulo, Inst Ciencias Ambientais Quim & Farmaceut, BR-04039032 Diadema, SP, BrazilUniv Fed Sao Paulo, Escola Paulista Med, BR-04023062 Sao Paulo, SP, BrazilAC Camargo Canc Ctr, Dept Patol, BR-01509010 Sao Paulo, SP, BrazilUniv Fed Sao Paulo, Inst Ciencias Ambientais Quim & Farmaceut, BR-04039032 Diadema, SP, BrazilUniv Fed Sao Paulo, Escola Paulista Med, BR-04023062 Sao Paulo, SP, BrazilWeb of Scienc
Using Whole Genome Sequences to Investigate Adenovirus Outbreaks in a Hematopoietic Stem Cell Transplant Unit
A recent surge in human mastadenovirus (HAdV) cases, including five deaths, amongst a haematopoietic stem cell transplant population led us to use whole genome sequencing (WGS) to investigate. We compared sequences from 37 patients collected over a 20-month period with sequences from GenBank and our own database of HAdVs. Maximum likelihood trees and pairwise differences were used to evaluate genotypic relationships, paired with the epidemiological data from routine infection prevention and control (IPC) records and hospital activity data. During this time period, two formal outbreaks had been declared by IPC, while WGS detected nine monophyletic clusters, seven were corroborated by epidemiological evidence and by comparison of single-nucleotide polymorphisms. One of the formal outbreaks was confirmed, and the other was not. Of the five HAdV-associated deaths, three were unlinked and the remaining two considered the source of transmission. Mixed infection was frequent (10%), providing a sentinel source of recombination and superinfection. Immunosuppressed patients harboring a high rate of HAdV positivity require comprehensive surveillance. As a consequence of these findings, HAdV WGS is being incorporated routinely into clinical practice to influence IPC policy contemporaneously
