We used this method to measure TEE in Chinese young men. Methods Sixteen healthy young men age 23±1 recruited. TEE was measured by the DLW method, by indirect calorimetry. We also conducted 24-h estimate energy requirements of the subjects. years with body mass index 22.0±1.4 kg/m2 were and basal energy expenditure (BEE) was determined activity, energy balance and factorial approach to Results TEE of subjects by DLW method was 9.45±0.57 M J/day (2258±180 kcal/day). The 24-h activity was 10.80±0.33 M J/day (2582±136 kcal/day). The energy requirement, derived from energy balance observations, was 9.93±1.32 M J/day (2373±315 kcal/day). The BEE of 6.65±0.28 M J/day (1589±67 kcal/day), calculated by the adjusted Schofield equation, was significantly higher (P〈O.O01) than that measured by indirect calorimetry, 5.99-±0.66 M J/day (1433-±158 kcal/day). The TEE derived from the factorial approach was 10.31-±0.43 M J/day (2463±104 kcal/day). Conclusion The TEE of Chinese young men measured by the DLW method was about 10% lower than the current recommended nutrient intake (RNI), suggesting that the RNI for Chinese men maybe overestimated. Further studies are warranted to determine the value of the estimated energy requirement.展开更多

A total of sixteen male schoolchildren were measured for their total daily energy expenditure (TEE) with the doubly labeled water (DLW) technique. The TEE obtained by the Actiheart monitor was calculated and validated against the DWL. The TEE was obtained adding the physical activity energy expenditure given by the Actiheart, plus the basal metabolic rate, and the energy cost of growth. The Pearson’s product‐moment correlation coefficient and the paired t‐test sample were measured in order to identify the association of the data and to evidence the differences between both measurements of TEE respectively. The Lin’s concordance correlation coefficient and the Bland-Altman plot evaluated the concordance of both methods. The correlation between the TEE obtained by DLW and the one calculated by Actiheart was r = 0.97, P < 0.001. The paired t-test showed no significant differences between both methods. Lin’s concordance correlation coefficient was Cb = 0.99, classified as almost perfect. The study validated the TEE calculated with Actiheart against the TEE measured by the DLW.展开更多

The totally non-positive completion asks which partial totally non-positive matrices have a completion to a totally non-positive matrix. This problem has. in general, a negative answer. Therefore, our question is for what kind of labeled graphs G each partial totally non-positive matrix whose associated graph is G has a totally non-positive completion?

Blume(LRTPG) in hamsters using proteomics technique.METHODS The hamsters were fed with a high fat diet to induce hyperlipidemia.Then LRTPG of high(1.2 g·kg^(-1)),medium(0.6 g·kg^(-1)) and low(0.3 g·kg^(-1)) doses were administrated daily for 4 weeks.Then the concentrations of plasma and hepatic lipids were determined using enzymic methods.The total protein was extracted from livers of the model group and the group treated with the high dose of LRTPG for label-free quantitative proteomics.RESULTS LRTPG significantly reduced the concentrations of plasma and hepatic lipids in hamsters fed a high fat diet.The proteomics data showed that a total of 2231 proteins were identified,and 549 proteins were found to be differentially expressed between the model group and the group treated with LRTPG.Among the 549 proteins,93 proteins were up-regulated and 59 proteins were down-regulated,and 397 proteins were absent or not.And some of these proteins were much related to the lipid metabolism.Further,gene ontology(GO) analysis indicated metabolic process,transport,oxidation-reduction process,phosphorylation,signal transduction,lipid metabolic process were the main biological processes that those differentially expressed proteins participated.KEGG pathway analysis showed that those proteins were involved in several metabolic pathways including oxidative phosphorylation,non-alcoholic fatty liver disease(NAFLD),PI3K-Akt signaling pathway,cAMP signaling pathway,cGMP-PKG signaling pathway.CONCLUSION The proteomics study could provide valuable clues to help us to understand the hypolipidemic mechanisms of LRTPG much better.展开更多
