The ρ(1S,2S)\rho(1S,2S), ψ(1S,2S)\psi(1S,2S), Υ(1S,2S)\Upsilon(1S,2S) and ψt(1S,2S)\psi_t(1S,2S) mesons in a double pole QCD Sum Rule

We use the method of double pole QCD sum rule which is basically a fit with two exponentials of the correlation function, where we can extract the masses and decay constants of mesons as a function of the Borel mass. We apply this method to study the mesons: $\rho(1S,2S)$, $\psi(1S,2S)$, $\Upsilon(1S,2S)$ and $\psi_t(1S,2S)$. We also present predictions for the toponiuns masses $\psi_t(1S,2S)$ of m(1S)=357 GeV and m(2S)=374 GeV.Comment: 14 pages, 11 figures in Braz J Phys (2016

Prevalence of katG Ser315 substitution and rpoB mutations in isoniazid-resistant Mycobacterium tuberculosis isolates from Brazil

SETTING: Four hundred and sixty-eight isoniazid (INH) resistant Mycobacterium tuberculosis isolates recovered from a selected Brazilian population. OBJECTIVE: To check for susceptibility to other chemotherapeutic drugs used in TB treatment, and to ascertain mutations involved in INH and rifampicin (RMP) resistance. DESIGN: Antimicrobial susceptibility to RMP, streptomycin and ethambutol (EMB) was evaluated by the resistance ratio method and pyrazinamide (PZA) by activity assay. Single strand conformation polymorphism (SSCP) and sequence analysis were performed in samples from this panel to confirm mutations in codon 315 of the katG and in a 69-bp region of the rpoB gene. RESULTS: Combined resistance to INH+RMP, INH+PZA, INH+EMB, and INH+RMP+PZA was shown in respectively 272 (58.1%), 126 (26.9%), 47 (10%), 116 (24.8%) isolates. No katG mutation was found in 19 (39.6%) of 48 strains tested. Ser315Thr substitution was found in 29 (60.4%). All RMP-resistant strains tested (n = 25) showed rpoB mutations. S531L substitution was found in 15 (60%). CONCLUSION: INH-resistant strains isolated from selected Brazilian populations frequently show resistance to other first-line anti-tuberculosis drugs. rpoB mutation was responsible for RMP resistance in all strains. Among INHr strains, katG mutations were shown in only 60.4%. Genetic approaches targeting the rpoB gene but not the katG gene have a high sensitivity to detect resistance among Brazilian M. tuberculosis strains.91879

Investigating the structure of X(4140) in QCD

Due to copyright restrictions, the access to the full text of this article is only available via subscription.In this work, the masses of the ground states coupling to molecular or tetraquark currents with JPC = 0++, 1++, 2++ are studied to investigate the structure of X(4140) exotic meson observed at J/ψφ invariant mass spectrum. We found that all currents predict ground states with masses of the same magnitude, which might be inter-pereted as the existance of at least three exotic structures with degenerate mass.TÜBİTA

"Near miss": repercussões e percepção da assistência recebida por mulheres sobreviventes egressas de uma unidade de terapia intensiva "Near miss": repercusiones y percepción de la asistencia recibida por mujeres sobrevivientes egresadas de una unidad de cuidados intensivos Repercussions of near miss and women's perception of care received in the critical care unit

OBJETIVO: Relatar as repercussões do "near miss" para a vida de mulheres sobreviventes e a percepção da assistência recebida. MÉTODOS: Trata-se de pesquisa qualitativa fundamentada na história oral. Foram utilizados conceitos da Antropologia Médica como referencial teórico. Para a coleta de dados foram realizadas entrevistas organizadas em narrativas com 13 mulheres egressas de uma UTI, durante o período de 2003 a 2005, residentes em Fernandópolis, SP. RESULTADOS: Os resultados mostraram que para algumas mulheres a experiência foi sofrida e deixou marcas, como a perda da fertilidade, sintomas depressivos, resignação ou falta de perspectiva de vida. Outras conseguiram ajustar-se e redirecionar suas vidas. Muitas se queixaram da assistência recebida, da negligência e ou imperícia dos profissionais durante o evento. CONCLUSÃO: Os resultados permitiram compreender a experiência das mulheres e apontaram para a desumanização do cuidado indicando a necessidade de estudos a respeito de questões éticas relativas às ações dos profissionais.<br>OBJETIVO: Relatar las repercusiones del "near miss" para la vida de mujeres sobrevivientes y la percepción de la asistencia recibida.

METHODS: This was a qualitative study using oral history interviewing. Medical anthropology served as the conceptual framework for the study. Data were collected from 2003 to 2005 through narrative interviews with 13 women who were discharged from a critical care unit and who were residents in Fernandópolis, SP. RESULTS: Some of the women reported that the experience of near miss brought suffering and sequelae such as infertility, depressive symptoms, and lack of perspectives in life. Other women were able to adjust and redirect their life. Many women complained of the care received, and the negligence and/or incompetence of health care professionals during the near miss event. CONCLUSION: The study's findings allowed us to understand the experience of this sample of women and suggested they receive a dehumanized care. There is a need for further studies regarding health care professional ethical behaviors
