Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) has been established as a powerful technique for the determination of metal and nonmetal distributions within biological systems with high sensitivity. An imaging LA-ICP-MS technique for Fe, Cu, Zn, and Mn was developed to produce large series of quantitative element maps in native(More)
OBJECTIVE Investigating the relation between social isolation and cognitive function will allow us to identify components to incorporate into cognitive interventions. METHOD Data were collected from 267 Appalachian older adults (M = 78.5, range 70-94 years). Overall cognitive functioning and specific cognitive domains were assessed from data of a(More)
BACKGROUND Oral health has been found to be associated with cognitive function in basic research and epidemiology studies. Most of these studies had no comprehensive clinical diagnosis on cognitive function. This study firstly reported the association between tooth loss and cognitive function among Chinese older population. METHODS The study included(More)
OBJECTIVES We investigated trends in activities of daily living (ADL) and instrumental activities of daily living (IADL) disability from 1998 to 2008 among elder adults in Shanghai, China. METHOD Our data came from 4 waves of the Shanghai Longitudinal Survey of Elderly Life and Opinion (1998, 2003, 2005, and 2008). ADL and IADL disabilities were recorded(More)
BACKGROUND West Virginia has the worst oral health in the United States, but the reasons for this are unclear. This pilot study explored the etiology of this disparity using culture-independent analyses to identify bacterial species associated with oral disease. METHODS Bacteria in subgingival plaque samples from twelve participants in two independent(More)
OBJECTIVES Little is known about variation in cognitive function across the aged population, or how use and costs of health care vary with cognitive impairment. This study was designed to create a typology of cognitive function in a nationally representative sample, and evaluate acute care use in relation to cognitive function, holding constant confounding(More)
Microsatellite or simple sequence repeat (SSR) is one of the most widely distributed molecular markers that have been widely utilized to assess genetic diversity and genetic mapping for important traits in plants. However, the understanding of microsatellite characteristics in Arachis species and the currently available amount of high-quality SSR markers(More)
This study aimed to examine the experience and knowledge of mild cognitive impairment (MCI) among Chinese family caregivers of individuals with MCI. The sample was recruited from memory clinics in Zhongnan Hospital in Wuhan, China. In-depth semi-structured interviews were used. Thirteen family members of individuals diagnosed with MCI participated in the(More)
In the present study. the metal-containing proteins in the roots ofCu-tole rant plant ElsllOltzia splendens were investigated. The proteins from the plant roots were extracted and separated by two-dimensional gel electrophoresis (2D GE). Las er ablation inductively coupl ed plasma mass spectrometry (LA-ICP-MS) was used to screen metal-containing proteins on(More)
INTRODUCTION Limited research has examined primary care providers' communication with patients about maintaining cognitive functioning. Our study's objective was to compare the perceptions of consumers and primary care providers related to beliefs and communication practices about lifestyle behaviors beneficial for overall health and for maintaining(More)
