BACKGROUND: Age-related neurodegenerative diseases share a number of important pathological features, such as accumulation of misfolded proteins as amyloid oligomers and fibrils. Recent evidence suggests that soluble amyloid oligomers and not the insoluble amyloid fibrils may represent the primary pathological species of protein aggregates.

RESULTS: We have produced several monoclonal antibodies that specifically recognize prefibrillar oligomers and do not recognize amyloid fibrils, monomer or natively folded proteins. Like the polyclonal antisera, the individual monoclonals recognize generic epitopes that do not depend on a specific linear amino acid sequence, but they display distinct preferences for different subsets of prefibrillar oligomers. Immunological …

Deficient Liver Biosynthesis Of Docosahexaenoic Acid Correlates With Cognitive Impairment In Alzheimer's Disease, Giuseppe Astarita, Kwang-Mook Jung, Nicole C. Berchtold, Vinh Q. Nguyen, Daniel L. Gillen, Elizabeth Head, Carl W. Cotman, Daniele Piomelli

Reduced brain levels of docosahexaenoic acid (C22:6n-3), a neurotrophic and neuroprotective fatty acid, may contribute to cognitive decline in Alzheimer's disease. Here, we investigated whether the liver enzyme system that provides docosahexaenoic acid to the brain is dysfunctional in this disease. Docosahexaenoic acid levels were reduced in temporal cortex, mid-frontal cortex and cerebellum of subjects with Alzheimer's disease, compared to control subjects (P = 0.007). Mini Mental State Examination (MMSE) scores positively correlated with docosahexaenoic/α-linolenic ratios in temporal cortex (P = 0.005) and mid-frontal cortex (P = 0.018), but not cerebellum. Similarly, liver docosahexaenoic acid content was lower in Alzheimer's …

Omega-3 Fatty Acids: Potential Role In The Management Of Early Alzheimer's Disease, Gregory A. Jicha, William R. Markesbery

Sanders-Brown Center on Aging Faculty Publications

Omega-3 fatty acids are essential for brain growth and development. They play an important role throughout life, as critical modulators of neuronal function and regulation of oxidative stress mechanisms, in brain health and disease. Docosahexanoic acid (DHA), the major omega-3 fatty acid found in neurons, has taken on a central role as a target for therapeutic intervention in Alzheimer's disease (AD). A plethora of in vitro, animal model, and human data, gathered over the past decade, highlight the important role DHA may play in the development of a variety of neurological and psychiatric disorders, including AD. Cross sectional and prospective …

Tobacco-Free Prison Policies And Health Outcomes Among Inmates, Alison R. Connell

University of Kentucky Doctoral Dissertations

This study was the first to examine the effect of tobacco policies in prisons on the health of inmates. Kentucky has two types of tobacco policies in its 16 state prisons: indoor smoke-free policies, where smoking is allowed outdoors and tobacco-free policies, in which no tobacco of any kind is allowed on the grounds of the prison. The smoking rate of inmates is three times higher than that of current smokers in the non-incarcerated population which results in high rates of tobacco-related health conditions such as heart disease and lung cancer.

A literature review discussed the evolution of tobacco policies …

Down Syndrome And Sexuality, Maria José Carvalho Sant'anna, Bruna Marques Bononi, André Chao Vasconcellos De Oliveira, Tadeu Silveira Renattini, Carla Franchi Pinto, Maria Lucia Passarelli, Veronica Coates, Hatim A. Omar

Pediatrics Faculty Publications

In recent years important gains and changes have been observed in the life of teenagers with Down syndrome (DS) with increased inclusion into society. This chapter will discuss adolescence and sexuality in teenagers with DS from a descriptive study of 50 patients with DS between the ages of 10 and 20 years. The mean age was 13.5 years, 50% females. 86% went to school with 62.2% in school for over six years. Of the patients that attended school, 60% went to special education school and only 10% read and wrote correctly. In evaluation of autonomy, 66% took shower, 78% performed …

Quality Of Life And Adolescents In Rural Kentucky, Hatim A. Omar, Søren Ventegodt, Joav Merrick

Pediatrics Faculty Publications

In many rural areas in Kentucky, adolescents lack the basic assets for a good quality of life, such as having caring adults, a safe place and useful activities after school. In this chapter we analyze data from middle and high school students referred to a comprehensive school based health promotion center (SBHPC). From August 2006 to February 2008, a total of 382 students (200 female, 182 male, aged 12-18 years) were referred to the SBHPC for help. Only two (0.5%) students had two parents living with them and 12 (3.1 %) had safe, organized after school activities. 19.9% of the …

Quality Of Life And Persons With Intellectual Disability: Can We Measure Qol In This Population?, Søren Ventegodt, Hatim A. Omar, Flemming Struve, Tove K. Nielsen, Isack Kandel, Joav Merrick

Pediatrics Faculty Publications

Quality of life (QOL) has been discussed by professionals working with persons with intellectual disability (ID) for some time, but since QOL is concerned with subjective well-being, satisfaction and happiness, how is it possible to measure, when the person in question is unable to communicate? Consciousness is believed to be an internal and personal thing, but we have done the simple experiment to ask observers to rate QOL of another person, also in sub dimensions like self-assessed physical and mental health, relationship with self, self-assessed sexual ability, self-assessed social ability, and we have found that people are able to assess …

Social Categories And Health Care Outcomes: African American Women And Hiv Survival In The Urban South, Alyson J. O'Daniel

University of Kentucky Doctoral Dissertations

This ethnographic research examines the daily life and institutional conditions under which low-income Black women in urban North Carolina perceived and attended to HIV health-related needs. I focus specifically on the interplay among women’s living conditions, programmatic service needs, and their strategies for navigating the local system of care to explore and refine the categorical label “low income.” I found that there were significant differences among study participants in terms of their monthly incomes and financial resources, housing quality and status, and personal experiences with incarceration and substance abuse. The economic differences among women translated into social differences within the …
