The purpose of this study was to determine whether superior concentric performance could be achieved in the bench throw with the use of additional eccentric loads. Fourteen male subjects performed bench throws in a smith machine with an eccentric-concentric load of 40-kg (40-40), and 40-kg concentric with additional eccentric loads of 20 (60-40), 30 (70-40), and 40 kg (80-40). A linear position...

Mitral annulus calcification (MAC) is a chronic, degenerative process in the fibrous base of the mitral valve. Although MAC was initially thought to be an age-related degenerative process, there is accumulating evidence that other mechanisms, such as atherosclerosis and abnormal calcium-phosphorus metabolism, also contribute to the development of MAC. Despite its frequency, the clinical relevan...

We study Witten’s background independent open-string field theory in the presence of a constant B-field at one loop level. The Green’s function and the partition function with a constant B-field are evaluated for an annulus.

background: the association of metabolic syndrome (ms) with left  ventricular (lv) hypertrophy is controversial. the objective of our study was to investigate the infl uence of ms on lv mass and geometry in community-based hypertensive patients among han chinese.materials and methods: this study included 1733 metabolic syndrome patients according to the international diabetes federation (idf) d...

Purpose: An appropriate activity of the knee agonist -antagonist muscles is important to resist against abnormal abduction-adduction moments loads around knee joint and reduce the risk of knee injuries. Exercise training has been commonly used as an intervention to improve neuromuscular activity within the synergic and/or agonist-antagonist muscles. However, maximizing the effectiveness of exer...

background around 7% of the world population have diabetes and suffer from its extensive complications. many studies are conducted on the positive effects of aerobic and resistance exercises on the reduction of body performances, but considering the available references, no specific study is conducted on the effect of eccentric exercises on patients with diabetes. objectives the current study a...

OBJECTIVES Mitral annuloplasty involves sewing a prosthetic ring to the mitral annulus. This involves a risk of damaging the surrounding structures in the left atrioventricular (AV) groove, particularly the left circumflex artery, which may be inadvertently sutured, causing an arterial occlusion. We have used cardiac computed tomography (CT) scans to study the three-dimensional relationship bet...

The inter-lamellar connectivity of the annulus fibrosus in the intervertebral disc has been shown to affect the prediction of the overall disc behaviour in computational models. Using a combined experimental and computational approach, the inter-lamellar mechanical behaviour of the disc annulus was investigated under conditions of radial loading. Twenty-seven specimens of anterior annulus fibro...

The hypothesis that the observed fluid annulus outside the wall of some capillaries is the reservoir of plasma responsible for ratios of organ hematocrit to large vessel hematocrit less than 1 is examined hydrodynamically. The extent to which the hematocrits can be reconciled on the basis of flow through a single capillary is examined. Results show that ratios between 0.5 and 1.0 can be account...

STUDY DESIGN Mechanically induced annular disruption of lumbar intervertebral discs followed by microstructural investigation. OBJECTIVE To investigate the role that elevated nuclear pressures play in disrupting the lumbar intervertebral disc's annulus fibrosus. SUMMARY OF BACKGROUND DATA Compound mechanical loadings have been used to recreate clinically relevant annular disruptions in vitr...
