Search for the neutral Higgs bosons of the minimal supersymmetric standard model in pp collisions at root s=7 TeV with the ATLAS detector

A search for neutral Higgs bosons of the Minimal Supersymmetric Standard Model (MSSM) is reported. The analysis is based on a sample of proton-proton collisions at a centre-of-mass energy of 7TeV recorded with the ATLAS detector at the Large Hadron Collider. The data were recorded in 2011 and correspond to an integrated luminosity of 4.7 fb-1 to 4.8 fb-1. Higgs boson decays into oppositely-charged muon or τ lepton pairs are considered for final states requiring either the presence or absence of b-jets. No statistically significant excess over the expected background is observed and exclusion limits at the 95% confidence level are derived. The exclusion limits are for the production cross-section of a generic neutral Higgs boson, φ, as a function of the Higgs boson mass and for h/A/H production in the MSSM as a function of the parameters mA and tan β in the mhmax scenario for mA in the range of 90GeV to 500 GeV.

Alterações cardiovasculares e morte súbita nas epilepsias Cardiovascular alterations and sudden death in epilepsy

A epilepsia é a doença neurológica crônica grave mais comum e o fenômeno da morte súbita nas epilepsias (SUDEP) é a causa direta de morte mais importante nesta doença. A causa da SUDEP ainda é desconhecida, no entanto, alterações cardiovasculares têm sido sugeridas como os mecanismos mais comuns. Sendo assim, enfatizamos nesta revisão a relação existente entre SUDEP e alterações cardiovasculares.<br>Epilepsy is the most common neurological disorder and sudden unexpected death in epilepsy (SUDEP) is the most important direct epilepsy-related cause of death . The cause of SUDEP is still unknown, however, the most commonly suggested mechanisms are cardiac abnormalities. Based on this, in this review the relationship between SUDEP and cardiac abnormalities has been emphasized
