“Background Cross sectional studies have indicated that vitamin D serostatus is inversely associated with adiposity It is unknown whether vitamin D deficiency is a risk factor for the development of adiposity in children
Objective We investigated the associations between vitamin D serostatus and ALK cancer changes in body mass Index (BMI in kg/m(2)) skinfold thickness ratio (subscapular to triceps) waist circumference and height in a longitudinal study in children from Bogota Colombia
Design We quantified plasma 25 hydroxyvitamin D [25(OH)D] concentrations in baseline samples of a randomly selected group of 479
schoolchildren aged 5-12 y and classified vitamin D status as deficient [25(OH)D concentrations <50 nmol/L] insufficient [25(OH)D concentrations >= 50 and <75 nmol/L] or sufficient [25(OH)D concentrations >= 75 nmol/L] We measured anthropometric variables annually for a median of 30 mo We estimated the average change in each anthropometric indicator according to base line vitamin D status by using multivariate mixed linear regression models
Results Vitamin D-deficient children had an adjusted BVD-523 MAPK inhibitor 0 1/y greater change in BMI than did vitamin D-sufficient children (P for trend = 0 05) Similarly vitamin D-deficient children had a 0 03/y (95% CI 0 01 0 05/y) greater change in subscapular to triceps skinfold thickness ratio and a 0 8 cm/y (95% CI 0 1 1 6 cm/y) greater change in waist circumference than did vitamin D-sufficient children Vitamin D deficiency was related to slower
linear growth in girls (-06 cm/y P = 0 04) but not in boys (0 3 cm/y P = 0 34) however an interaction with sex was not statistically significant
Conclusion Vitamin D serostatus was inversely associated with the development of adiposity in school BMS-345541 cost age children Am J Clin Nutr 2010 92 1446-51″
“The continuity and Poisson equations are solved numerically to obtain J-V characteristics and photoconversion efficiency of a two-junction solar cell. The cell consists of a top junction comprised of nanowires with bandgap of 1.7 eV grown on a bottom junction comprised of a Si substrate. The lattice relaxation possible in nanowires permits lattice-mismatched III-V material growth on Si, thereby achieving the optimum bandgaps in a two-junction cell. The model indicates a limiting efficiency of 42.3% under a concentration of 500 Suns (AM1.5 D spectrum). This limiting efficiency is similar to that calculated for the planar lattice-matched triple-junction Ge/InGaAs/InGaP cell. Methods of fabricating the nanowire/Si cell are discussed including requirements for nanowire sidewall surface passivation. The model indicated that passivation of the nanowire sidewall surfaces that produces a surface recombination velocity of 3000 cm.
