Dispositional Joy As A Mediator Of Adverse Childhood Experiences And Parental Reflective Functioning, Mollie Brady Jan 2022

Dispositional Joy As A Mediator Of Adverse Childhood Experiences And Parental Reflective Functioning, Mollie Brady

Walden Dissertations and Doctoral Studies

Parental reflective functioning (PRF) is a critical contributor to positive parenting outcomes. Early adverse experiences are a significant risk factor for insensitive parenting practices and poor PRF. Researchers have found that positive emotions, such as dispositional joy (DJ), influence both parenting outcomes and building resilience to stressful events. Adverse childhood experiences (ACEs), DJ, and PRF have been studied extensively in the literature as separate or paired constructs. However, to date, no studies have examined how these variables interact with each other. The purpose of this quantitative study was to explore the relationship between ACEs, DJ, and PRF, and the mediating …

Relationship Between Early Years’ Activities Of Daily Living And Alzheimer’S Disease Onset, Linyi Fan

Walden Dissertations and Doctoral Studies

A few promising studies have indicated that activities of daily life (ADL) may be a useful way of predicting Alzheimer’s Disease (AD). However, the existing cross-sectional studies fail to show how ADLs in early years predict AD, and how social factors influence health either in addition to or in interaction with individual risk factors. Using a social epidemiology framework, this study examined the relationship between early years’ ADL and the development of AD in later years. This quantitative study included 4,526 participants derived from the Health and Retirement Study (HRS) dataset. The dependent variable was whether the participant has been …

A Serotonin-Mediated Aversive Mechanism Influences Individually Variable Resilience Toacquire And Relapse To Cocaine-Seeking, Ying S. Chao Jan 2022

A Serotonin-Mediated Aversive Mechanism Influences Individually Variable Resilience Toacquire And Relapse To Cocaine-Seeking, Ying S. Chao

MUSC Theses and Dissertations

Although cocaine and other psychostimulants are highly rewarding, they also produce aversive effects that influence drug-seeking, and that are stronger in some individuals than others for poorly understood reasons. We now find in rats that cocaine depolarizes neurons of the rostromedial tegmental nucleus (RMTg), a major GABAergic afferent to midbrain dopamine neurons, and a driver of punishment learning. This activation is mediated by post-synaptic serotonin 2C receptors, and is particularly strong in subsets of animals having heightened aversive responses to cocaine, among whom it slows the initial acquisition of cocaine self-administration and reduced cue-induced relapse for cocaine after extinction. These …

Nanorings To Probe Mechanical Stress Of Single-Stranded Dna Mediated By The Dna Duplex, Karen Zagorski, Tommy Stormberg, Mohtadin Hashemi, Anatoly B. Kolomeisky, Yuri L. Lyubchenko

Journal Articles: Pharmaceutical Sciences

The interplay between the mechanical properties of double-stranded and single-stranded DNA is a phenomenon that contributes to various genetic processes in which both types of DNA structures coexist. Highly stiff DNA duplexes can stretch single-stranded DNA (ssDNA) segments between the duplexes in a topologically constrained domain. To evaluate such an effect, we designed short DNA nanorings in which a DNA duplex with 160 bp is connected by a 30 nt single-stranded DNA segment. The stretching effect of the duplex in such a DNA construct can lead to the elongation of ssDNA, and this effect can be measured directly using atomic …
