The aim of the present study was to evaluate the effect of prolonged inhibition of beta-oxidation on glucose and lipid muscle forearm metabolism and cGMP and endothelin-1 forearm release in patients with type 2 diabetes mellitus and ischemic cardiomyopathy. Fifteen patients were randomly allocated in a double-blind cross-over parallel study with trimetazidine (20 mg tid) or placebo lasting 15 d...

BACKGROUND Abnormal upper arm-forearm muscle synergies after stroke are poorly understood. We investigated whether upper arm function primes paralyzed forearm muscles in chronic stroke patients after Brain-Machine Interface (BMI)-based rehabilitation. Shaping upper arm-forearm muscle synergies may support individualized motor rehabilitation strategies. METHODS Thirty-two chronic stroke patien...

OBJECTIVE Our aim was to compare physical activity and biochemical markers with bone mineral acquisition in rhythmic gymnasts and ballet dancers. METHODS Weight, height, body mass index, nutritional intake, bone age and menstrual histories were analyzed in nine rhythmic gymnasts, twelve ballet dancers and fourteen controls. Bone mineral density (BMD) was assessed by X-ray absorptiometry at th...

OBJECTIVE To determine whether African American children with forearm fractures have decreased bone mineral density and an increased prevalence of vitamin D deficiency (serum 25-hydroxyvitamin D level ≤ 20 ng/mL) compared with fracture-free control patients. METHODS This case-control study in African American children, aged 5 to 9 years, included case patients with forearm fracture and contro...

We introduce a new kinematic model describing the motion of the human forearm bones, ulna and radius, during forearm rotation. During this motion between the two forearm extrem-positions, referred to as supination (palm up) and pronation (palm down), effects occur, that cannot be explained by the the established kinematic model of R. Fick from 1904. Especially, the motion of the ulna is not pro...

The relative role of protein synthesis and degradation in determining postprandial net protein deposition in human muscle is not known. To this aim, we studied forearm leucine and phenylalanine turnover by combining the arteriovenous catheterization with tracer infusions, before and following a 4 h administration of a mixed meal in normal volunteers. Forearm amino acid kinetics were assessed in...

BACKGROUND Treatment of forearm fracture nonunion is challenging. Several surgical techniques for the treatment of forearm nonunion have been reported. OBJECTIVES The aim of this prospective study was to evaluate the effects of the radial forearm bone graft technique in cases with forearm nonunion. PATIENTS AND METHODS We treated 7 patients with forearm nonunions via radial forearm bone fla...

conclusions pedicled pibf is a new option for treating distal radius fracture non:union:. the results are predictable in achieving :union: and good function, and this technique can be successfully used in cases with extensive soft-tissue damage or infection. background non:union: of distal radius fractures is disabling. treatment is difficult and the results are not predictable. however, poster...

AIMS We evaluated whether black race is independently associated with arterial endothelial dysfunction. The pathophysiological basis for race-related differences in cardiovascular disease (CVD) risk has not been established. Endothelial dysfunction, which precedes obstructive atherosclerotic disease, may contribute to CVD disparities. Accordingly, we evaluated race-related differences in digita...

Electromyography (EMG) has been widely used for the assessment of musculoskeletal functions and the control of electrical prostheses, which make use of the EMG signal generated by the contraction of the residual muscles. In spite of the successful applications of EMG in different fields, it has some inherent limitations, such as the difficulty to differentiate the actions of neighboring muscles...
