Dehydroepiandrosterone (DHEA) is a C-19 adrenal steroid and the most abundant circulating hormone in humans. Since circulating levels decline in late adulthood, treatment of humans with DHEA has been suggested to have beneficial health effects....
Liquid gallium (Ga) spontaneously alloys with thin films of metals such as Ag, Au, Pt Al, and Cu at near or even below room temperature resulting in rapid self-assembly of nanostructures. In this dissertation, studies of the formation of these...
Down syndrome--Patients; Williams syndrome--Patients; Social interaction in children; Social perception in children
The present project examined the regulatory function of social referencing in two neurodevelopmental disorders that have been well defined genetically and are characterized by differing patterns of socio-cognitive development: Down syndrome (DS)...
This thesis is an economic and historical examination of Keeneland racetrack in Lexington, Kentucky. The material commences with a historical overview of the role of sport and recreational activities in the United States. Putting sport and leisure...
4-hydroxy-2-nonenal (4-HNE) and propene-2-al (acrolein) are highly reactive á,â-unsaturated aldehydes. 4-HNE and acrolein are generated in vivo as products of lipid peroxidation. These aldehydes are implicated in the onset of several diseases...
Few previous studies have compared microbial communities in subterranean and surface environments. Chemical analyses used to characterize the surface and cave microbial environments indicated limited exchange between surface and subsurface waters....
Previous research has indicated the important role of visual information in the speech perception process. These studies have elucidated the areas of the brain involved in the processing of audiovisual stimuli. The McGurk effect, an audiovisual...
This dissertation describes galvanic exchange of silver (Ag) nanostructures with PdCl42- in 1) various PdCl42- concentrations, 2) the presence of 0.1 M cetyitrimethylammonium bromide (CTAB), and 3) the presence of 0.1 M potassium bromide (KBr). It...
Electroactive polymers (EAPs), including conducting polymers (CPs) such as polyaniline (PAn), and hydrogels are exciting areas of research in disciplines such as biomedical engineering, with the goal of creating low-cost, lightweight, non-toxic...
This dissertation is a hypothesis-driven research oriented study to determine the role of the pituitary-tumor transforming gene (PTTG) in ovarian cancer, specifically if it is involved in neoplastic transformation leading to tumorigenesis through...
This dissertation describes research focused on the synthesis, polymerization and
applications of cationic aminooxy lipids. An efficient and convenient method was
developed to stabilize liposomes using 'click chemistry'. The 'click...
Linseed oil is the oil from the plant linum usitatissiumum. It is not a new oil, for we read that the Greeks and Romans used it, not as it is used today, but as a food, and it is still used for that purpose in some countries, especially in Russia,...
Surface active agents; Rendering industry--Waste disposal; Air filters
Meat is a major component of the diet of an American. However, humans do not consume one-third to one-half of each animal raised for their needs. The leftover materials are subjected to processing in the meat rendering industry. The rendering...
Determining the etiology of skeletal malocclusion is an important diagnostic step in treatment planning patients with maxillofacial anomalies. Aims: To describe cranial base morphology using cone beam computed tomography (CBCT) images and correlate...
Juvenile delinquents--Rehabilitation; Juvenile delinquents--Mental health services; Juvenile delinquents--Psychology; Juvenile delinquents--Substance use
Juvenile delinquency with co-occurring substance abuse and mental health disorders has become an increasing problem within the United States. In part this can be attributed to the excessive number of delinquent youth entering the juvenile justice...
Lead Zirconate Titanate (PZT), known for its ferroelectric properties, is widely used in micro-electromechanical (MEMS) and nano-electromechanical (NEMS) devices. PZT is a ceramic material that is most commonly found in its sol gel form, which...
Gold nanoparticles (AuNPs) have attracted enormous attention in the field of nanotechnology for applications such as, immunoassay, drug delivery, contrast enhancement and tumor therapy. The typical range of gold nanoparticles varies from 1– 150...
Various vision tasks are usually confronted by appearance variations due to changes of illumination. For instance, in a recognition system, it has been shown that the variability in human face appearance is owed to changes to lighting conditions...
Neurosphere forming cells (NSFCs) have been derived from cultures of adult olfactory neuroepithelium obtained from patients and cadavers in serum rich medium. These neural progenitors remain undifferentiated when maintained in serum rich medium but...
Integrated circuits--Design and construction; Integrated circuits industry--Technological innovations
Lithographic processes for printing device structures on integrated circuits plays a major role in the semiconductor industry. This project aims at designing and fabricating a programmable mask for a direct write lithography system which can...
