Down-Regulation Of Natural Killer Cell Activation In Response To Influenza Virus In Older Adults, Yu Jing
Down-Regulation Of Natural Killer Cell Activation In Response To Influenza Virus In Older Adults, Yu Jing
Theses and Dissertations in Biomedical Sciences
Immune senescence contributes to influenza-associated high mortality and morbidity and reduced vaccine efficacy in elderly people. Type I T cell (Thl)-mediated immunity plays a significant role in Immune responses to influenza infection and vaccination. Natural killer (NK) cells secrete significant amount of IFN-7 , a hallmark Thl cytokine, in response to influenza infection. How aging influences human NK cell IFN-7 production in response to influenza virus has not been well documented. In this study we employed human peripheral blood mononuclear cells (PBMC) and performed intracellular cytokine staining and flow cytometry primarily to investigate how aging influences NK cell activation with …
Vital Tooth Whitening Effects On Oral Health-Related Quality Of Life In Older Adults, Ann Michelle Poindexter
Vital Tooth Whitening Effects On Oral Health-Related Quality Of Life In Older Adults, Ann Michelle Poindexter
Dental Hygiene Theses & Dissertations
This study determined if vital tooth whitening affects oral health-related quality of life (OHRQOL) in adults ≥50-years old, and if tooth whitening promotes individuals to seek regular professional dental care and participation in social activities. Using a two-group, single blind, randomized, pre-test-post-test design, 62 participants were enrolled. The experimental group used a whitening product twice daily for three weeks, while the control group used no whitening products. Tooth color satisfaction was assessed using the Tooth Color Satisfaction Scale and was correlated with overall oral health-related quality of life. The Oral Health Impact Profile (OHIP), used as the pre-test …
Changes In Formal-Informal Caregiving In Elderly Stroke Survivors, Holly Anne Beard
Changes In Formal-Informal Caregiving In Elderly Stroke Survivors, Holly Anne Beard
Health Services Research Dissertations
The purpose of this study is to determine the extent to which the Andersen and Aday Model of Health Services Use to predict cross-sectional and longitudinal differences in the caregiving source among stroke survivors (n=477) over a six-year period. This study involves a secondary analysis of a longitudinal panel study focusing upon three waves of interview data from the HAS/AHEAD study spanning 1998 through 2002. Multinomial logistic regression was utilized to examine caregiving source cross-sectionally at each wave. Clustered multinomial logistic regression was used to examine relationships between predictor variables in the model and caregiving source across waves while holding …
