OBJECTIVE To examine the relation between the frequency of enhancing magnetic resonance imaging lesions and their characteristics of enhancement and atrophy in patients with early relapsing multiple sclerosis. DESIGN Analysis of number of enhancing lesions, ventricular volumes and diameters, and lesion characteristics on monthly magnetic resonance imaging scans during natural history follow-u...

The Calcific Aortic Valve Disease (CAVD), already in early stage of Aortic Valve Sclerosis (AVS), may be associated with a major cardiac event. The authors present a report of cardiac death by AVS explaining the possible pathogenetic mechanism involved in exitus. In the literature several studies reports that, already in the early stage of the disease, a reduction of ventricular function could ...

Babault, Nicolas, Michel Pousson, Yves Ballay, and Jacques Van Hoecke. Activation of human quadriceps femoris during isometric, concentric, and eccentric contractions. J Appl Physiol 91: 2628–2634, 2001.—Maximal and submaximal activation level of the right knee-extensor muscle group were studied during isometric and slow isokinetic muscular contractions in eight male subjects. The activation le...

Despite full voluntary effort, neuromuscular activation of the quadriceps femoris muscle appears inhibited during slow concentric and eccentric contractions. Our aim was to compare neuromuscular activation during maximal voluntary concentric and eccentric quadriceps contractions, hypothesizing that inhibition of neuromuscular activation diminishes with resistance training. In 15 men, pretrainin...

OBJECTIVE Functional ankle instability (FAI) afflicts many athletes. Several causes of FAI have been implicated, including peroneal muscle weakness. Traditional musculoskeletal rehabilitation programs have focused on concentric muscle strength. The purpose of our study was to compare concentric and eccentric isokinetic and isometric eversion ankle strength measurements between subjects identifi...

General SFM methods give poor results for images captured by constrained motions such as planar motion of concentric mosaics (CM). In this paper, we propose new SFM algorithms for both images captured by CM and composite mosaic images from CM. We first introduce 1D affine camera model for completing 1D camera models. Then we show that a 2D image captured by CM can be decoupled into two 1D image...

This study's objective was to determine whether 14 days of dietary creatine supplementation preceding an injurious bout of eccentric contractions affect the in vivo strength loss of mouse anterior crural muscles. Three groups of nine mice each were fed a meal diet for 14 days, one group at each of three levels of creatine supplementation (i.e., 0, 0.5, and 1% creatine). Electrically stimulated ...

Neurodegenerative diseases are the hereditary and sporadic diseases which are characterized by progressive neuronal loss of the nervous system and are emerging as the leading cause of death, disabilities, and a socioeconomic burden due to an increase in life expectancy. There are many neurodegenerative diseases including Alzheimer’s disease, Parkinson’s, disease, amyotrophic lateral...
