FUNDAMENTO: A cirurgia cardiovascular vem passando por transformações em decorrência do avanço das técnicas percutâneas, do tratamento clínico e da prevenção primária. OBJETIVO: Avaliar a incidência e a mortalidade de operações cardiovasculares realizadas no Instituto do Coração (InCor-HCFMUSP). MÉTODOS: A PARtir do banco de dados do Instituto do Coração, foram analisadas as operações cardiovasculares realizada...
The DFTB method, as well as its self-consistent charge corrected variant SCC-DFTB, has widened the range of applications of fundamentally well established theoretical tools. As an approximate density-functional method, DFTB holds nearly the same accuracy, but at much lower computational costs, allowing investigation of the electronic structure of large systems which can not be exploited with conventional ab ini...
OBJECTIVE: To describe clinical and neuroimaging (SPECT) characteristics of Brazilian patients with Parkinson's disease (PD) and mutations in PARK2 or PARK8 genes. METHOD: A total of 119 patients meeting clinical criteria for PD were evaluated. RESULTS: Of all patients studied, 13 had mutations in either PARK2 (n=9) or PARK8 genes (n=4). No statistically significant differences in clinical characteristics in bo...
The Hospício de Juquery, near the city of São Paulo (Brazil) was founded in 1896 and after few years it was decided that the institution should have the best possible facilities to study neuropathology. In 1921, a young psychiatrist, Antonio Carlos Pacheco e Silva was sent to the Hôpital de la Salpêtrière (Paris) to study neuropathology. There, Pacheco e Silva (later Prof.Pacheco e Silva) befriended Konstantin ...
Experimentos utilizando sistemas de observação global, foram realizados excluindo um ou mais tipos de observação do esquema global de assimilação de dados/previsão de tempo do Centro de Previsão de Tempo e Estudos Climáticos do Instituto Nacional de Pesquisas Espaciais - CPTEC/INPE (Global Physical-space Statistical Analysis System - GPSAS). Estes experimentos indicam como efetivamente as observações são usadas...
BACKGROUND: Neonates with severe neurological impairment are often unable to swallow, necessitating gastrostomy for feeding. Because of the risk of developing severe reflux, this procedure is often associated with fundoplication. OBJECTIVE: To assess the safety and efficacy of gastrostomy and Nissen fundoplication in 22 neonates with swallowing difficulties due to serious neurological impairment. METHOD: All ch...
The chemical analysis of the acetone, chloroform, toluene and methanol extracts of a pitch sample was carried out by IR and GC-MS, leading to the identification of sixty nine compounds, including fatty acids, alcohols and hydrocarbons. Analysis of the acetone extractive of a eucalyptus wood used in Brazil for pulp production was also carried out, resulting in identification of fifty nine compounds, including ma...
Aerial parts of Mikania glomerata Sprengel, were irradiated with gamma rays in an apparatus with a Cesius-137 source in two different doses: 3.5 and 5.0 KGy. Double-blind HPLC studies on fluid extracts and tinctures prepared from the irradiated drug material were utilized to verify possible chemical changes. Extracts from the same plant (untreated) were used as standards. The results obtained showed that there ...
OBJETIVO: Avaliar os benefícios a médio prazo do uso exclusivo de enxertos arteriais em pacientes com doença aterosclerótica coronária triarterial submetidos à revascularização completa do miocárdio. MÉTODO: Entre julho/95 e julho/97, 137 pacientes consecutivos foram submetidos à revascularização miocárdica com uso exclusivo de enxertos arteriais. Destes, 112 (81,7%) eram do sexo masculino e a idade variou de 3...
OBJECTIVE: To further verify the efficacy and safety of locally manufactured lamivudine on patients with chronic hepatitis B (CHB). METHODS: 2200 patients with CHB were recruited and received lamivudine orally 100 mg once daily for 12 months. The efficacy assessments included virologic response rate (defined by the absence of serum HBV DNA, HBeAg loss and HBeAg/HBeAb seroconversion), percentage of patients wit...
