Study Of Lipid Raft Formation In Model Membranes And Cells, Priyadarshini Pathak

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Ordered membrane domains, (conventionally called lipid rafts) are tightly packed sphingolipid and cholesterol rich domains, proposed to co-exist with disordered domains, in the plasma membrane. In spite of many cellular functions allotted to rafts, their direct detection in cells has been difficult. Rafts may be too small to detect and this could easily be misinterpreted as their absence. For this reason, the contention that in the absence of detergent Triton X-100 (commonly used to isolate rafts), domains may not exist in the lipid mixture resembling the plasma membrane, was investigated. A novel FRET pair variation assay in which, FRET pairs …

Mercury, Polychlorinated Biphenyls, And Immune Response Indicators In The National Health And Nutrition Examination Survey (Nhanes), Carolyn Michele Gallagher

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Autoimmune diseases are among the leading causes of death among young and middle-aged women, and prevalence is increasing; however, autoimmune etiology is poorly understood. The need to investigate relationships between environmental factors and human autoimmune responses has been prioritized by the World Health Organization and the National Institutes of Health (NIH), yet epidemiologic research is sparse. Mercury (Hg) and polychlorinated biphenyls (PCBs) are ubiquitous and persistent environmental contaminants with early evidence of immunotoxic associations. Immunotoxic responses fall on a continuum, with the normal range of immune responses at the center, immunostimulation and autoimmunity at one end, and immunosuppression and infection …

Assessing The Nutritional Health Outcomes Of African American Women With Hiv And Substance Abuse Disorders Using A Socioecological Approach, Meena Mahadevan, John Ruzsilla

Department of Nutrition and Food Studies Scholarship and Creative Works

It is well established that poor nutritional status leaves HIV-positive substance abusers especially vulnerable to an increased risk of opportunistic infections and other illnesses. Socioecological frameworks have been useful for identifying multiple influences on health risks, leading to the development and evaluation of promising community-based interventions for diseases such as cancer and diabetes. This article presents a conceptual model, based on the socioecological approach, to examine the mechanisms and pathways by which the various contextual factors unique to HIV-positive African American women with substance abuse disorders intersect to impact their nutritional health outcomes. The mediating effects of the interpersonal, environmental, …

Long-Term Integrated Studies Show Complex And Surprising Effects Of Climate Change In The Northern Hardwood Forest, Peter M. Groffman, Charles T. Driscoll, Chris E. Johnson, Lindsey E. Rustad, Pamela H. Templer

Civil and Environmental Engineering - All Scholarship

Evaluations of the local effects of global change are often confounded by the interactions of natural and anthropogenic factors that overshadow the effects of climate changes on ecosystems. Long-term watershed and natural elevation gradient studies at the Hubbard Brook Experimental Forest and in the surrounding region show surprising results demonstrating the effects of climate change on hydrologic variables (e.g., evapotranspiration, streamflow, soil moisture); the importance of changes in phenology on water, carbon, and nitrogen fluxes during critical seasonal transition periods; winter climate change effects on plant and animal community composition and ecosystem services; and the effects of anthropogenic disturbances and …

Influences Of A Cladophora Bloom On The Diets Of Amblema Plicata And Elliptio Dilatata In The Upper Green River, Kentucky, Jennifer Maria Yates

Masters Theses & Specialist Projects

Freshwater mussels are the most imperiled group of freshwater invertebrates globally. Recent research suggests a better understanding of mussel feeding ecology may facilitate and improve conservation efforts. The use of stable isotopes is becoming an increasingly common method to study aquatic food webs. Carbon (C) and nitrogen (N) are two of the most frequently employed elements in food web studies. Differences in natural abundance of ¹³C/¹²C can indicate which food sources are the basal sources of carbon incorporated into a consumer’s tissue, while the ratio of ¹⁵N /¹⁴N provides a method of assessing trophic …

Mississippi Kids Count: Child Abuse & Neglect In Mississippi, Jeremy Bressman, Kevin Golembiewski, Abram Orlansky, Crystal Redd

Delta Directions: Publications

While the number of children subject to abuse or neglect has dropped over the past decade, it is undoubtedly the case that child abuse and neglect remains one of the most serious concerns for children in the United States. Nationwide, nearly 702,000 children (or 9.3 out of 1,000) were subject to some form of abuse in the Fiscal Year 2009, a drop from even the year before (10.3 victims per 1,000 children), and a significant drop from earlier recorded findings in 1995 (15 victims per 1,000). Still, the numbers remain alarmingly high, particularly given the dire consequences. A number of …

The Dental Safety Net In Montgomery County: A Status Report, Sequoia Y. Butcher

Master of Public Health Program Student Publications

Background: Adult oral health has been identified as a major public health problem by the United States Surgeon General. A substantial number of adults between the ages of 20 and 64 have untreated tooth decay. There are limited treatment options for adults without dental insurance. Low-income adults must turn to free/low cost clinics, or private dentists that accept Medicaid to receive dental care. However, these resources are often limited. When the resources are not available these adults are left to deal with untreated tooth decay which can lead to worsening conditions and other health issues.

Methods: Eleven key-informant interviews were …

Mechanical Contributors To Sex Differences In Idiopathic Knee Osteoarthritis, Daniel P. Nicolella, Mary I. O'Connor, Roger M. Enoka, Barbara D. Boyan, David A. Hart, Eileen Resnick, Karen J. Berkeley, Kathleen A. Sluka, C. Kent Kwoh, Laura L. Tosi, Richard D. Coutts, Wendy M. Kohrt

Orthopaedic Surgery Faculty Publications

The occurrence of knee osteoarthritis (OA) increases with age and is more common in women compared with men, especially after the age of 50 years. Recent work suggests that contact stress in the knee cartilage is a significant predictor of the risk for developing knee OA. Significant gaps in knowledge remain, however, as to how changes in musculoskeletal traits disturb the normal mechanical environment of the knee and contribute to sex differences in the initiation and progression of idiopathic knee OA. To illustrate this knowledge deficit, we summarize what is known about the influence of limb alignment, muscle function, and …

A Symbiotic View Of Life: We Have Never Been Individuals, Scott F. Gilbert, J. Sapp, A. I. Tauber

Biology Faculty Works

The notion of the "biological individual" is crucial to studies of genetics, immunology, evolution, development, anatomy, and physiology. Each of these biological subdisciplines has a specific conception of individuality, which has historically provided conceptual contexts for integrating newly acquired data. During the past decade, nucleic acid analysis, especially genomic sequencing and high-throughput RNA techniques, has challenged each of these disciplinary definitions by finding significant interactions of animals and plants with symbiotic microorganisms that disrupt the boundaries that heretofore had characterized the biological individual. Animals cannot be considered individuals by anatomical or physiological criteria because a diversity of symbionts are both …

Does Economic Decline Contribute To A Decline In Children’S Food Security?, Kimberly Groover, Bradford Mills, George Davis

University of Kentucky Center for Poverty Research Discussion Paper Series

Most Americans believe that children should not experience persistent worry about the quality or quantity of food consumed due to low household resources. Since 1995, the USDA has tracked children’s food security based upon household responses to the annual Current Population Survey Food Security Supplement (CPS-FSS). During this time, a small, but recently growing, share of U.S. households report multiple indicators of reduced food intake and disrupted eating patterns among children due to inadequate resources to obtain food (Coleman- Jenson et al, 2012). The USDA classifies children as food secure, low food secure, or very low food secure based upon …

Building Healthy Communities: Integrating Walkability Concepts Into Local Land Use Planning, Jenna Danelle Muhlbach

Community and Regional Planning Program: Theses

In recent years, American communities have been diagnosed with several chronic health diseases such as diabetes, heart disease and obesity. Several researchers attribute sedentary lifestyles as one of the contributing factors to chronic diseases. The lack of physical exercise can be blamed by the auto-dependent suburbia lifestyle that many generations have become accustomed to. Poor land use developments have roads and freeways dominating the use of space, with the intent of having an automobile get from one place to another as efficiently as possible. This has allowed places to be much further apart therefore it has had a negative impact …

Curriculum Design For An Integrated Language Arts Class At The High School Level Utilizing A Multi-Genre American Studies Approach, Susan K. Biddulph

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Curriculum integration and multi-genre approaches to education are acknowledged to be beneficial to both student learning styles and skill development; however, due to time and budget constraints, many teachers do not implen1ent these approaches. This language arts curriculum utilizes a theme-centered approach that smoothly integrates many subject areas and encourages skill development while adhering to the Utah Common Core Curriculum and incorporating multiple lean1ing styles. The theme of the curriculum is gender role expectations throughout history. While the units primarily rely on primary texts, they also incorporate numerous secondary texts in multiple subject areas and require both formal and informal …

Factors Influencing Metal Accumulation In Two Estuarine Fish, Jessica Dutton

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Small forage fish are a conduit for the transfer of metals from lower trophic levels to their predators and potentially human consumers of contaminated seafood. A metal bioaccumulation model has been developed for aquatic organisms, including fish, to determine: (1) the predicted body burden of metals at steady-state based upon the rate of metal uptake and loss from aqueous and dietary sources, and (2) the percentage of accumulated metal attributable to dietary exposure. However, this model assumes that rates of metal uptake and loss following aqueous and dietary exposure are constant and that fish only consume one type of prey. …

Pepsin And Salivary Amylase Biomarkers Of Microaspiration In Oral And Tracheal Secretions Of Intubated Patients, Aurea Middleton

HIM 1990-2015

Introduction: The presence of an endotracheal tube (ETT) increases the risk for microaspiration of secretions around the ETT. Biomarkers of pepsin and salivary amylase may be used to identify microaspiration in intubated patients because of their naturally occurring presence in the stomach or oral cavity and non-occurrence in the respiratory tract. Microaspiration may be difficult to detect until pulmonary complications, such as lung injury or infection, occur. This study assessed the presence of pepsin and salivary amylase in oral and tracheal secretions of ventilated adults. Method(s): This is a secondary analysis of data collected from 11 critically ill, adult patients …

Iron Acquisition By The Dental Pathogen Aggregatibacter Actinomycetemcomitans., Porscha Larai Jefferson 1986-

Electronic Theses and Dissertations

The dental pathogen A. actinomycetemcomitans, a Gram- negative organism, has been associated with aggressive forms of periodontitis. A. actinomycetemcomitans requires iron to grow. In the host, iron-binding proteins such as transferrin, lactoferrin, hemoglobin, and ferritin, maintain a low free-iron concentration. Microorganisms, however, have evolved complex systems to efficiently harvest iron. The iron acquisition systems encoded in the genome of A. actinomycetemcomitans are likely tailored towards the specific survival strategies needed to survive in the oral biofilm. The objectives of this project were to determine the growth of A. actinomycetemcomitans in different iron sources and to examine the expression of the …

Vitamin D Deficiency And Cultural Influences Among Muslim Women In Southern Illinois, Durar Kassim Shakir

Theses

This study is an analysis of the cultural influences that affect the prevalence of vitamin D deficiency among Muslim women from sun-rich countries, who now reside in Southern Illinois. Previous studies examine the prevalence of vitamin D deficiency among this population, while neglecting to examine the extent of cultural influences which can affect the likelihood of having this disorder. Low serum levels of 25(OH)D can occur when there are low levels of vitamin D intake, and when exposure to sunlight is limited. Muslim women are more prone to vitamin D deficiency due to traditional attire, regardless of migration. Upon surveying …
