Biological self-time is the characteristic of individual biosystems and invariantly describes the various dynamic processes in organisms. This biological invariance is introduced by using 2 basic theorems: Allometric scaling and the Weibull psychometric function. Our objective was to precisely describe the timing phenomenon in biosystems and provide a framework to further develop this analogy for other fields.展开更多

However, information on the contribution ofsex differences in quality of life and cognitive function is scarce. Therefore, this study aimed to investigate potentialdifferences in cognitive function and QoL between males and females. For this study, we recruited 382 healthy subjectsaged 19–79 years from communities in Southern Taiwan region,China. Cognitive function and QoL were assessed using the UCSD Performance-based Skills Assessment, Brief Version (UPSA-B) and World Health Organization Quality ofLife Instruments (WHOQOL-BREF), respectively. The effects of sex, age groups, and interaction of sex and ageon the UPSA-B and WHOQOL-BREF scores were examined. We found that the financial and communicationdomains of the UPSA-B showed declining trends with age in both sexes, although these trends were more obviousin females than in males. In the domain of Physical Capacity, QoL showed an age-increased trend in males, whileQoL in the Environment domain showed an age-increased trend in females. Regarding the relationships betweencognitive function and QoL, we found that the financial skill and communication skill of UPSA-B was positivelycorrelated to the psychological well-being domain of WHOQOL-BREF, in males of age <40 years. In conclusion,our findings demonstrate differential relationships between cognitive function and QoL between males and females,which could serve as a basis for further study between cognitive function and quality of life in communities.展开更多
