Many species of fungi undergo a dimorphic transition to switch from a unicellular yeast-like growth form to a filamentous growth form. Ustilago maydis undergoes such a transition, in response to successful mating events and subsequent host cues, to...
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,...
Cortical and tectal inputs to the caudal LPN in the rat were examined using anatomical and physiological techniques. Pyramidal cells in layer 6 of the visual cortex and wide-field vertical cells in the stratum opticum of the superior colliculus...
Myocardial infarction; Glucose--Metabolism; Mitochondrial DNA
Heart failure is a leading cause of morbidity and mortality in the USA. During the development of heart failure, many cardiac parameters change at the same time including fuel metabolism, oxidative stress and mitochondrial function. Each of these...
Heart--Hypertrophy; Heart--Physiology; Sugar in the body; Metabolism; Diabetes--Research
Heart failure is recognized as a major cause of death among diabetics. In type I and II diabetes, glucose uptake, glycolysis and pyruvate oxidation are impaired, and fatty acid utilization increases. These alterations in metabolism contribute...
Heart failure is the most frequent cause of mortality in western countries. Currently, there is no cure treatment for heart failure and the long term survival rate following heart failure is poor, with one third of patients dying within a year of...
Quorum sensing (Microbiology); Cellular signal transduction; Bacterial genetics
Quorum sensing in the oral pathogen Aggregatibacter actinomycetemcomitans is dependent upon the soluble signaling molecule AI-2, but it is not known how the initial detection of AI-2 is coupled to the downstream regulation of gene expression that...
This research project describes the application of a master/slave configuration of processors to study a comparison of alternative material handling configurations for automated manufacturing. Such a study usually requires a large number of...
Exocytosis of intracellular granules is critical for conversion of inactive, circulating neutrophils to fully activated cells. The p38 MAPK pathway plays a central role in neutrophil exocytosis, although its mechanism of action is unknown. We used...
Drug delivery systems; Curcumin--Therapeutic use--Administration
Curcumin, a plant derived compound has shown significant potency against various chronic diseases like cancer in cell culture and animal studies. However, the introduction of this compound into clinical setting is limited by its poor oral...
The trucking industry is the largest freight sector, making up about 70 percent of all domestic shipment in the United States and contributes greatly the American economy. About 10 billion tons of goods are shipped annually and of that, about...
The purpose of this dissertation was to demonstrate that a new method of direct intracellular energy delivery was effective in maintaining viability of in vitro Human Umbilical Vein Endothelial Cells (HUVECs) when exposed to chemical ischemia for...
Hypoxia is characterized by an inadequate oxygen supply to the tissues in
proportion to their metabolic needs, and is a primary factor in traumatic CNS
injury, strokes, cardiopulmonary diseases, and obstructive sleep apnea. The
cAMP-dependent...
Diabetes--Psychological aspects; Diabetes--Treatment; Diabetics--Mental health
The importance of maximizing self-management and quality of life is well documented in the diabetes literature. Although maintaining self-care is known to be important for individuals with type 2 diabetes, this is often difficult to maintain over...
The pulvinar is the largest nucleus of the human dorsal thalamus and is affected in a variety of brain disorders, such as schizophrenia. The experiments described in this dissertation elucidate key features of tecto-pulvino-cortical pathways as a...
Recent studies indicate post-translational deacetylation by members of the superfamily of histone deacetylase complexes (HDACs) is necessary for oligodendrocyte precursor cell (OPC) differentiation into mature oligodendrocytes (OLs). However, it...
Characterization of the optical and electrical properties of organic solar cell materials is of prime importance to organic solar cell design. This thesis describes the use of capacitive photocurrent measurements to study the exciton generation and...
Depression is one of the most frequent causes of disability worldwide. It can
affect the psychological, social, and physical wellbeing of those that suffer from it, the
majority of which are women. Depression has been linked to immune activation as...
Nanomaterials have many intriguing applications in biology and medicine. Unique properties such as enhanced electrical properties, increased chemical reactivity and resistance to degradation, novel optical properties and comparable size to that of...
High-throughput sequencing has provided a myriad of genetic data for thousands of organisms. Computational analysis of one data type, expressed sequence tags (ESTs) yields insight into gene expression, alternative splicing, tissue specificity gene...
