Compara????o das vers??es completa e reduzida da Escala de Compet??ncia de Estu...

Este estudo objetivou comparar as duas vers??es da Escala de Compet??ncia de Estudo -ECE(C&T), uma a original com 54 itens e outra reduzida com 19 itens, por meio da Teoria de Resposta ao Item (modelo Rasch). Participaram 129 universit??rios de ambos os sexos, com idades variando de 17 a 48 anos (M = 24.65, DP = 6.54). Os coeficientes de precis??o obtidos foram de .91 para escala com 54 itens e de .90 para a d...

Sustained remission from depressive-like behavior depends on hippocampal neurog...

We thank M Carneiro and L Martins for technical assistance. AM-P, LP, MM and SM received fellowships from the Portuguese Foundation for Science and Technology (FCT). This work was supported by FCT (PTDC/SAU-NEU/105180/2008) and the ICVS. ; Impairment of hippocampal neurogenesis has been associated with the expression of depressive-like symptoms and some studies have suggested neurogenesis as a critical factor ...

CYP2C19*2 and prognosis after an acute coronary syndrome: Insights from a Portu...

BACKGROUND: Clopidogrel requires oxidation dependent on the cytochrome P450 enzyme 2C19 (CYP2C19) to form its active metabolite. The importance of loss-of-function alleles (particularly CYP2C19*2, 681G>A) in poor platelet response to clopidogrel is well recognized. OBJECTIVE: To investigate the prevalence and prognostic impact of the CYP2C19*2 allele in a local acute coronary syndrome (ACS) population. METHOD...

Efeito da temperatura de queima em composição de massa para revestimento cerâmi...

Este trabalho tem por objetivo desenvolver formulação de massa para revestimento cerâmico vitrificado utilizando o fundente nefelina sienito com argila caulinítica. Foram preparadas formulações com 0, 30 e 50% em peso de nefelina sienito em mistura com a argila. Corpos-de-prova foram obtidos por prensagem uniaxial a 30 MPa para queima nas temperaturas de 1100 ºC, 1150 ºC e 1200 ºC. As propriedades físicas e mec...

Left ventricular end diastolic pressure and acute coronary syndromes

BACKGROUND: Data is lacking in the literature regarding the prognostic impact of left ventricular-end diastolic pressure (LVEDP) across acute coronary syndromes (ACS). OBJECTIVE: To assess LVEDP and its prognostic implications in ACS patients. METHODS: Prospective, longitudinal and continuous study of 1329 ACS patients from a single center between 2004 and 2006. Diastolic function was determined by LVEDP. Pop...

Efeito da utilização de areia no processamento e nas propriedades de cerâmica v...

Este trabalho teve por objetivo reformular uma típica massa de telhas produzida no município de Campos dos Goytacazes, RJ, variando a quantidade de areia. As matérias-primas, massa argilosa e areia, foram inicialmente submetidas a ensaios de caracterização mineralógica, química e física. Foram preparados corpos de prova por extrusão para queima nas temperaturas de 850, 950 e 1050 ºC. As propriedades avaliadas f...

Can we improve outcomes in patients with previous coronary artery bypass surger...

INTRODUCTION AND OBJECTIVES: Prognosis and in-hospital management of patients with acute coronary syndrome (ACS) and a history of coronary artery bypass graft (CABG) surgery are still debated. The objective of this study was to characterize ACS patients with a CABG and to compare their in-hospital and postdischarge outcomes with those of patients without a CABG. METHODS: This ongoing prospective observational s...

A Importância de um ECG Normal em Síndromes Coronarianas Agudas sem Supradesniv...

BACKGROUND: Admission ECG has a major impact on the diagnosis and management of non-ST elevation acute coronary syndromes (ACS). OBJECTIVE: To assess the impact of the admission ECG on prognosis over non-ST ACS. Population: prospective, continuous, observational study of 802 non-ST ACS patients from a single center. METHODS: Patients were divided in 2 groups: A (n=538) - Abnormal ECG and B (n=264) - Normal ECG....
