Let log ( d dx ) be the generator of the1-parameter group { d dxa |a ∈ R} of fractional order differentiations acting on the space of operators of Mikusinski ([5]). The Lie algebra glog generated by log ( d dx ) and log x is a deformation and can be regarded as the logarithm of Heisenberg Lie algebra. We show glog is isomorphic to the Lie algebra generated by d ds log(Γ(1 + s)) and d ds . Hence...
• To be aware of how malnutrition presents and how to screen, assess, and monitor patients for nutritional risk and for response to nutritional support; • To be aware of the importance of the routine screening all patients for malnutrition and of the continued monitoring of those at risk; • To appreciate the value of such diagnostic methods combined with measures of growth and development to in...
Technologies for the measurement of bone mineral density and other parameters of bone strength at peripheral skeletal sites have been studied since the 1960s. Single-energy Photon Absorptiometry (SPA), Radiographic Absorptiometry (RA), Radiogrametry (RG), Single-energy X-ray Absorptiometry (SXA), Peripheral Dual-energy X-ray Absorptiometry (pDXA), and Quantitative Ultrasonometry (QUS) have been...
48 CMAJ, January 7, 2014, 186(1) © 2014 Canadian Medical Association or its licensors Two patients with grade III obesity (body mass index [BMI] ≥ 40), a 31-year-old man (A) and a 26-year-old woman (B), underwent Roux-en-Y gastric bypass on vertical banded gastroplasty. Both patients followed the same nutritional and postsurgical approach. After 12 months, both patients achieved a similar reduc...
INTRODUCTION Osteoporosis represents one of the most frequent comorbidity among HIV patients. The current standard method for osteoporosis diagnosis is dual-energy X-ray absorptiometry. Calcaneal quantitative ultrasound can provide information about bone quality. The aims of this study are to compare these two methods and to evaluate their ability to screen for vertebral fracture. METHODS Thi...
