Objectives: To test the hypothesis that the QTc of any lead of the ECG predicts death after stroke, and to determine which lead of the ECG carries the greatest risk of cardiac death when its QTc is measured. Design: Standard 12 lead ECGs were analysed by one observer who was blind to patient outcome. Setting: A major teaching hospital in Scotland. Patients: 404 stroke survivors were studied at ...

Foram conduzidos quatro ensaios em delineamento blocos casualizados com sete tratamentos repetições. T1 - 0 kg ha-1 nitrogênio, sem inoculação (controle); T2 80 N, inoculação; T3 160 (SI)...

Pure six-fold symmetry (V6) internal rotation poses significant challenges to experimental and theoretical determination, as the very low torsional barriers result in huge tunneling splittings difficult to identify and to model. Here we resolved the methyl group internal rotation dynamics of 2,6- and 3,5-difluorotoluene using a newly developed computer code especially adapted to V6 problems. Th...

Simulate the computer-aided design of gymnastic device in the pre-development stage by applying CATIA V6 software, and explore the matching degree between gymnastic device design and human body database using the theory and data of Ergonomics. Build the improved model of gymnastic device based on CATIA V6 virtual human data and explore the best evaluation method of man-machine simulation for gy...

The number, location, extent, and functional properties of the cortical areas that occupy the medial parieto-occipital cortex (mPOC) have been, and still is, a matter of scientific debate. The mPOC is a convoluted region of the brain that presents a high level of individual variability, and the fact that many areas of mPOC are located within very deep sulci further limits the possibility to inv...

The extensive global climate observing system (GCOS) reference upper-air network (GRUAN) datasets provide a chance to validate newly released Atmospheric Infrared Sounder (AIRS) version 7 (v7) products over the Arctic. This manuscript reports on analysis performed evaluate errors from AIRS 6 (v6) and v7 temperature profiles characterize derived low-level inversion (LLI) representativeness in Ar...

OBJECTIVES We examined the prognostic significance of precordial ST segment depression among patients with an acute inferior myocardial infarction. BACKGROUND Although precordial ST segment depression has been associated with a poor prognosis, this correlation has not been adequately quantified, partly because of small sample sizes and methodologic limitations in previous studies. METHODS W...

Protease inhibitor resistance still poses one of the greatest challenges in treating HIV. To better design inhibitors able to target resistant proteases, a deeper understanding is needed of the effects of accumulating mutations and the contributions of active- and nonactive-site mutations to the resistance. We have engineered a series of variants containing the nonactive-site mutations M46I and...

Vision is important for estimating self-motion, which is thought to involve optic-flow processing. Here, we investigated the fMRI response profiles in visual area V6, the precuneus motion area (PcM), and the cingulate sulcus visual area (CSv)-three medial brain regions recently shown to be sensitive to optic-flow. We used wide-view stereoscopic stimulation to induce robust self-motion processin...
