Truncation, Cross-Linking And Interaction Of Crystallins And Intermediate Filament Proteins In The Aging Human Lens, Roger Truscott, Jason Mcarthur, Andrew Aquilina, Shi-Ping (Jim) Su
J. A. Aquilina
The optical properties of the lens are dependent upon the integrity of proteins within the fiber cells. During aging, crystallins, the major intra-cellular structural proteins of the lens, aggregate and become water-insoluble. Modifications to crystallins and the lens intermediate filaments have been implicated in this phenomenon. In this study, we examined changes to, and interactions between, human lens crystallins and intermediate filament proteins in lenses from a variety of age groups (0-86 years). Among the lens-specific intermediate filament proteins, filensin was extensively cleaved in all postnatal lenses, with truncated products of various sizes being found in both the lens cortical …
Economic Transition And New Patterns Of Parent-Adult Child Coresidence In Urban China, Qian Forrest Zhang
Economic Transition And New Patterns Of Parent-Adult Child Coresidence In Urban China, Qian Forrest Zhang

This study uses national data from the 1996 Life History and Social change in Contemporary China survey (N = 3,087) to gauge the effect of the economic transition on parent-adult child coresidence in urban China. Previous studies find that, thanks to state actions, traditional patterns in coresidence persisted in post-Mao urban China. This study still finds high levels of coresidence. China's aging population, coupled with an underdeveloped social security system, means that the traditional role of family will remain strong. It also uncovers three new patterns, however, best explained as caused by changes in the economic realm. First, the coresidence …
