BACKGROUND There is large variation in treatment responses in children with cerebral palsy. Experimental and clinical results suggest that dopamine neurotransmission and brain-derived neurotrophic factor (BDNF) signalling are involved in motor learning and plasticity, which are key factors in modern habilitation success. We examined whether naturally occurring variations in dopamine and BDNF ge...
BACKGROUND The aim of the present study was to characterize temporal changes in cyclic variation of ultrasonic integrated backscatter (IBS), which reflects intrinsic contractile performance, in patients with reperfused acute myocardial infarction (AMI) and to elucidate the clinical value of tissue characterization in predicting myocardial viability. METHODS AND RESULTS We recorded short-axis ...
Introduction: Dietary diversity score (DDS) and Food variety score (FVS) are the appropriate measures used to evaluate the overall quality of dietary patterns. However, their associations with the serum levels of micronutrients remain unclear. The present study aimed to investigate the correlations between DDS/FVS and serum ferritin and magnesium status in the non-athlete femal...
OBJECTIVE To evaluate the performance of the QFractureScores for predicting the 10 year risk of osteoporotic and hip fractures in an independent UK cohort of patients from general practice records. DESIGN Prospective cohort study. SETTING 364 UK general practices contributing to The Health Improvement Network (THIN) database. PARTICIPANTS 2.2 million adults registered with a general pract...
BACKGROUND A number of chest radiographic scores have been developed to assess the severity of respiratory disease in cystic fibrosis but critical statistical evaluation has been limited. In particular, the chest radiograph component of the National Institutes of Health (NIH) clinical score has not previously been validated. Three different chest radiograph scores have been compared and the ass...
heuristics are often used to provide solutions for flow shop scheduling problems.the performance of a heuristic is usually judged by comparing solutions and run times on test cases.this investigation proposes an analytical alternative ,called asymptotic convergence ,which tests the convergence of the heuristic to a lower bound as problem size grows. the test is a stronger variation of worst cas...
