Speech Articulation Assessment Using Dynamic Magnetic Resonance Imaging Techniques

Magnetic Resonance Imaging (MRI) has been successfully applied on real-time analysis of the articulators during speech production along the whole vocal tract, with good signal-to-noise ratio and without ionizing effects. Because speech dynamic events need a minimal sampling rate, an improvement on the temporal resolution of MRI systems is demanded. Our aim is to describe a dynamic MRI technique to acquire and a...

Cardiac resynchronization therapy is effective even in elderly patients with co...

PURPOSE: The purpose of this study was to compare the effects of cardiac resynchronization therapy (CRT) in elderly patients (> or =65 years) with younger patients and to assess the impact of comorbidities in CRT remodeling response. METHODS: This is a prospective study of 87 consecutive patients scheduled for CRT who underwent clinical and echocardiographic evaluation before and 6 months after CRT. A reductio...

Identification of 'super-responders' to cardiac resynchronization therapy: the ...

AIMS: Some patients show such an important clinical improvement and reverse remodelling after cardiac resynchronization therapy (CRT) that anatomy and function approach normal. These patients have been called 'super-responders'. The aim of our study was to identify predictors of becoming a super-responder after CRT. METHODS AND RESULTS: Eighty-seven consecutive patients who underwent CRT were prospectively stu...

Pacing biventricular: experiência inicial

INTRODUCTION: Biventricular pacing has been studied for the treatment of chronic heart failure (CHF). This technique seems to be able to improve symptoms and exercise tolerance, in patients with advanced CHF and prolonged QRS duration. OBJECTIVE: To present our experience with biventricular pacing in the management of severe CHF. METHODS: Between June 2000 and March 2001, 8 patients with dilated cardiomyopath...

Sleep patterns and sleep-related complaints of Brazilian interstate bus drivers

Sleep-related complaints have become a highlight for physicians as well as public health administrators. Studies of sleep patterns and sleep-related complaints of shift workers have been useful in minimizing reduction in the quality of life due to the warping of the sleep-wake cycle. The objective of the present study was to assess patterns of sleep, sleep-related complaints as well as physical activity and sco...

Toxicidade para lagartas de Phthorimaea operculella (Zell.) dos aleloquímicos 2...

Avaliou-se a toxicidade para Phthorimaea operculella (Zell.) dos aleloquímicos 2-trídecanona e 2-undecanona, presentes nos exsudatos glandulares dos tricomas de Lycopersicon spp. Determinou-se a toxicidade dos exsudatos de L. hirsutum f. glabratum PI134417 (DL50), do 2-tridecanona (dose letal: DL50 e concentração letal: CL50) e do 2-undecanona (CL50) para lagartas de primeiro ínstar desse inseto. A DL50 foi de ...
