The results show that there are five healthy functions incorporated effectively in bamboo-charcoal modified polyesters, such as good far-infrared radiation, good UV protection, certain negative ion emission, certain antibacteria and good absorption functions. The metal elements and carburets are mainly responsible for far-infrared, negative ion emission functions. UV prevent/on function results mainly from the carbon elements. The absorbability and bacteriostasis functions lie in the porous structures.展开更多

Bondi et aL found that ε4 carriers perform significantly worse on the California Verbal Learning Test than non-carriers in non-demented old subjects （mean age, 72 years）ε11. But the results are not entirely consistent. For example, Scarmeas et aL found no effect of the E4 allele on neuropsychological performance[2] in young adults, and Jochemsen et al. found that the ε4 allele is associated with age-related cognitive decline[3]. Furthermore, protective and negative effects of the E2 allele on cognition are inconsistent[4＇ s]. APOE E2 is thought to be a protective allele for AD in the elderly population due to its role in the superior cognitive performance of ε2 carriers compared to E3 or E4 carriers[5]. However, the ε2 allele has also been found to have a negative effect on AD pathology[4].展开更多
