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...

Letter to the editor resting energy expenditures in haemodynamically compromised cardiac patients The impetuous development of malnutrition due to increased catabolic requirements as a consequence of critical illness is a well-known clinical problem (1). Adequate energy provision in critically ill patients improves clinical outcomes (2, 3), decreases hospital costs (4), and recommended by inter...

BACKGROUND The determination of resting energy expenditure (REE) is the primary step for estimating the energy requirement of an individual. Although numerous equations have been formulated for predicting metabolic rates, there is a lack of studies addressing the reliability of those equations in chronic kidney disease (CKD). Thus, the aim of this study was to evaluate whether the main equation...

BACKGROUND The effects of gastric bypass (GBP) on resting energy expenditure (REE) are not well known. AIM To evaluate the changes in REE and its relationship with body composition in severe and morbid obese women before and six and twelve months after GBP. PATIENTS AND METHODS Twenty three women aged 37+/-10 years, with a body mass index of 44+/-4 kg/m(2), were evaluated before, six and tw...

There is some evidence to suggest that ethnic differences in energy expenditure in adults may modulate different propensities for obesity. However, there is lack of data for the components of energy expenditure in young children of different ethnic backgrounds. In this study, we examined total energy expenditure (TEE), resting energy expenditure (REE), and physical activity-related energy expen...

It is not clear what dietary intake standards should be used for children with abnormal body size. To investigate the energy requirements of short-stature children with no underlying diseases, their resting energy requirements (REE) were measured by indirect calorimetry. The short-stature group consisted of 30 prepubertal children with short stature and with no underlying diseases (age 6y±2) ...
