Total Energy Expenditure (TEE) and energy requirements are commonly estimated from equations predicting Resting Energy Expenditure (REE) multiplied by a Physical Activity (PA) coefficient that accounts for both PA energy expenditure and the thermogenic effect of food. PA coefficients based on PA self-reports are a potential source of error that has not been evaluated. Therefore, in this study w...

Individuals with high plasma norepinephrine (NE) levels at rest have a smaller reduction in resting energy expenditure (REE) following β-adrenergic blockade. If this finding extends to the response to a meal, it could have important implications for the role of the sympathetic nervous system in energy balance and weight gain. We hypothesized high muscle sympathetic nerve activity (MSNA) would b...

The present study was performed to further investigate the adaptive component of thermogenesis that appears during prolonged energy restriction. Fifteen obese men and twenty obese women underwent a 15-week weight-loss programme. During this programme, body weight and composition as well as resting energy expenditure (REE) were measured at baseline, after 2 and 8 weeks of energy restriction (-29...

BACKGROUND Weight loss is a frequently occurring problem in patients with lung cancer due to an increased resting energy expenditure (REE) and a decreased energy intake. The aim of the present study was to compare the metabolic and inflammatory characteristics of patients with small cell lung carcinoma (SCLC) and non-small cell lung carcinoma (NSCLC). The metabolic parameters of the lung cancer...

OBJECTIVES (1) To examine the validity of existing prediction equations (PREE) for estimating resting energy expenditure (REE) in obese Chinese children, (2) to correlate the measured REE (MREE) with anthropometric and biochemical parameters and (3) to derive a new PREE for local use. DESIGN Cross-sectional study. SUBJECTS 100 obese children (71 boys) were studied. MEASUREMENTS All subjec...

OBJECTIVE The rate of weight gain in preterm infants who are exposed to music seems to improve. A potential mechanism could be increased metabolic efficiency; therefore, we conducted this study to test the hypothesis that music by Mozart reduces resting energy expenditure (REE) in growing healthy preterm infants. DESIGN. A prospective, randomized clinical trial with crossover was conducted in 2...

Carbonatite-associated rare-earth-element (REE) deposits are the most significant source of the world's REEs; however, their genesis remains unclear. Here, we present new Sr-Nd-Pb and C-O isotopic data for Cenozoic carbonatite-hosted giant REE deposits in southwest China. These REE deposits are located along the western margin of the Yangtze Craton that experienced Proterozoic lithospheric accr...

Background: Little is known about the determinants of individual variability in body weight and fat loss after gastric bypass surgery or about the effects of massive weight loss induced by this surgery on energy requirements. Objectives: The objectives were to determine changes in energy expenditure and body composition with weight loss induced by gastric bypass surgery and to identify presurge...

Objective: To verify whether sleeping habits affect adaptive thermogenesis (i.e. greater than predicted decrease in resting energy expenditure, REE) in overweight and obese adults subjected to caloric restriction. Methods: A total of 123 overweight and obese men and women (mean ± SD age, 41.1 ± 6.0 years; mean ± SD body mass index, 33.2 ± 3.6 kg/m2) were tested before and 17.2 ± 3.7 weeks after...

Raman spectra are sensitive to the structural and chemical characteristics of the phosphate mineral whitlockite. The number and specific frequency of the Raman bands in the 970 A m ' spectral region caused by the vl symmetric stretching mode within the P043tetrahedra differ for REE-rich whitlockite (single, asymmetric band), REE-poor Caor Na-whitlockite (doublet), and terrestrial Hantaining whi...
