Dual-energy X-ray absorptiometry (DXA) is a valid technique for measuring the fat, bone and lean (muscle, organs and water) masses of the body. We evaluated relationships of BMI (kg/m2) with independent measurements of fat and lean masses using DXA in 226 adult volunteers. The evaluation was an application of a general approach to compositional data which has not previously been used for descri...

BACKGROUND Impact of body fat distribution on bone mineral content (BMC) and density (BMD) at different sites has not been studied in type-2 diabetes (T2DM). This study aimed to compare BMC and BMD in normal (BMI < 25 kg/m(2)) and increased BMI (BMI ≥ 25 kg/m(2)) T2DM patients with age and BMI matched normal controls, and evaluate the impact of lean mass and body fat distribution parameters on ...

BACKGROUND Post-menopausal hormone therapy (pHT) induces changes in both body composition and bone mineral density (BMD). METHODS In 109 post-menopausal women beginning either tibolone 2.5 mg (n=29), tibolone 1.25 mg (n=42) or estradiol 2 mg plus norethisterone acetate 1 mg (E2 + NETA) (n=38), we assessed body composition, total and regional BMD by dual energy X-ray absorptiometry, and the se...

In the present study, we performed a meta-analysis to assess the ability of leucine supplementation to increase the muscle protein fraction synthetic rate and to augment lean body mass or leg lean mass in elderly patients. A literature search was conducted on Medline, Cochrane, EMBASE and Google Scholar databases up to 31 December 2013 for clinical trials that investigated the administration of...

Background Authors assessed lean body mass (fat free tissue), upper and lower, and bone mineral density (BMD) in patients of osteoporotic bone distal radius fracture (DRF) and degenerative rotator cuff tear (RCT) patients of shoulder. We predict inferior muscle mass and osteoporosis are more frequent in DRF group than RCT group. Methods Between January 2016 and June 2017, overall 38 of DRF an...

OBJECTIVE To determine if primary hand osteoarthritis (OA) is associated with abnormal bone and anthropometric traits. METHODS We used DXA to measure total body bone mineral density (BMD), femoral neck width (bone size) and total body lean and fat mass in 39 subjects with hand OA (primary DIP and/or CMC I) and 164 controls. Data are presented as mean Z-scores or Odds Ratios (OR) with 95% conf...

A numerical model of the lattice Boltzmann method (LBM) utilizing least-squares finite-element method in space and the Crank-Nicolson method in time is developed. This method is able to solve fluid flow in domains that contain complex or irregular geometric boundaries by using the flexibility and numerical stability of a finite-element method, while employing accurate least-squares optimization...

1. Standard radioisotope dilution techniques employing [3H]water and [22Na]sodium chloride have been used to determine the total body water and total exchangeable sodium of 20 male and 10 female normal Ghanaians (Africans) aged 19--25 years. 2. Lean body mass and total body fat are calculated as a percentage of body weight; the total exchangeable sodium values have been expressed in relation to...
