PSICOFARMACOGENÉTICA

Psychiatric disorders are chronic, recurrent and are responsible for huge social and individual costs. Psychopharmacology is a growing field with and an increasing number and quality of drugs, which have improved treatment efficacy and decreased adverse effects. Pharmacogenetics is a relatively recent science that study genetics influence on drug response and adverse effects. In these review, we point to the major findings in psycopharmacogenetics and comment on the perspectives for the scientific community and clinicians in Brazil.Doenças psiquiátricas são patologias crônicas, recorrentes e promotoras de desarranjo e custo social extenso. A psicofarmacologia apresenta um número crescente de medicações eficazes e sua evolução acontece no sentido de aumentar a eficácia do tratamento de pacientes refratários, assim como reduzir os freqüentes efeitos colaterais associados com as medicações tradicionais. A farmacogenética é uma ciência relativamente recente que estuda as influências genéticas na resposta a droga e que pode vir a ser ferramenta essencial para o entendimento do funcionamento de drogas, assim como dos efeitos colaterais de medicações. Nessa revisão foram levantados os principais achados farmacogenéticos com antipsicóticos e antidepressivos e comentadas as perspectivas da farmacogenética na comunidade científica e clínica no Brasil

Search for the standard model Higgs boson in the H to ZZ to 2l 2nu channel in pp collisions at sqrt(s) = 7 TeV

A search for the standard model Higgs boson in the H to ZZ to 2l 2nu decay channel, where l = e or mu, in pp collisions at a center-of-mass energy of 7 TeV is presented. The data were collected at the LHC, with the CMS detector, and correspond to an integrated luminosity of 4.6 inverse femtobarns. No significant excess is observed above the background expectation, and upper limits are set on the Higgs boson production cross section. The presence of the standard model Higgs boson with a mass in the 270-440 GeV range is excluded at 95% confidence level.Comment: Submitted to JHE

Search for New Physics with Jets and Missing Transverse Momentum in pp collisions at sqrt(s) = 7 TeV

A search for new physics is presented based on an event signature of at least three jets accompanied by large missing transverse momentum, using a data sample corresponding to an integrated luminosity of 36 inverse picobarns collected in proton--proton collisions at sqrt(s)=7 TeV with the CMS detector at the LHC. No excess of events is observed above the expected standard model backgrounds, which are all estimated from the data. Exclusion limits are presented for the constrained minimal supersymmetric extension of the standard model. Cross section limits are also presented using simplified models with new particles decaying to an undetected particle and one or two jets
