Herbig Ae stars are young stars usually surrounded by gas and dust in the form of a disk and are thought to evolve into planetary systems similar to our own. We present a multi-wavelength examination of the disk and environment of the Herbig Ae...
The ability of L. pneumophila to cause disease depends on its replication in alveolar macrophages. Infectivity and the expression of various virulence traits is triggered at post exponential growth phase. We show that unlike quiescent macrophages,...
The synthesis of the methyl thioperoxide-bridged dimolybdenum(V) dimer, [Mo2(NTo)2(S2P(OEt)2)2S(O2CMe)(SOMe)], was improved and the compound was structurally characterized by crystallography. The compound proved to be very stable to light and heat....
Marginal inference for waiting times in multi-stage time-to-event models is complicated by right censoring of observations as well as the prior history of events in the model. In general, complications arise due to the evolution of the censoring...
Oxidative stress-induced immunosuppression could be due to a decrease in CD4 + T lymphocyte activation or proliferation. 4-Hydroxynonenal (HNE), an end product of lipid peroxidation, and its protein adducts act as markers of oxidative stress. In...
A connected matching in a graph is a set of disjoint edges such that, for any pair of these edges, there is another edge of the graph incident to both of them. This dissertation investigates two problems related to finding large connected matchings...
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...
Integrins are major receptors for cell adhesion to the extracellular matrix, and play key roles in various cellular processes including adhesion, migration, proliferation and survival. Apart from developmental and physiological events, integrins...
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...
The mechanisms by which estrogens regulate mitochondrial activity are not completely understood. Chronic treatment of ovariectomized rats with estradiol (E 2 ) increased the amount of Nuclear Respiratory Factor-1 (NRF-1) protein in cerebral blood...
This thesis describes 1) the kinetics of vapor phase place exchange reactions on films of gold monolayer protected clusters (Au MPCs) to alter the functionality of the Au MPCs, 2) applications of the reaction for altering chemiresistive sensing...
Vicinal dithioethers and alkenyl thioethers were synthesized under environmentally
friendly conditions using alkyne and thiol in water. Alkynes were also used to develop a
multibond-fonning reaction that fonned cyclic ketones or ketoesters through...
Here, I address the function of the carboxy-terminal hydrophobic helix of the pro-apoptotic protein Bax. There has been considerable controversy as to whether this sequence is required for the targeting and insertion of Bax into the mitochondrial...
In the present study, we report the synthesis of thermally stable mesoporous gallium oxide and novel gallium-niobium mixed oxides employing Evaporation Induced Self-Assembly (EISA), Self-Assembly Hydrothermal-Assisted (SAHA) and Self-Assembly...
The field of graph theory has been indubitably influenced by the study of planar graphs. This thesis, consisting of five chapters, is a historical account of the origins and development of concepts pertaining to planar graphs and their...
Complement, an early recognition system of innate immunity that senses local tissue damage and infection, cross-talks with and regulates other signaling systems, including Toll-like receptor (TLR) pathways. In the context of periodontitis,...
The fundamental importance of a definite knowledge of the quantity of each amino acid yielded by the several food proteins justifies the expenditure of much effort in studying the analytical methods in order that these may be improved or their...
Reperfusion of the ischemic lung causes pulmonary arteriolar vasoconstriction and reduces alveolar perfusion. Lung ischemia-reperfusion (IR) injury leads to platelet and leukocyte activation which could contribute to decreased alveolar perfusion...
MicroRNAs (miRNAs) regulate gene expression at the post-transcriptional level by repressing translation or stimulating mRNA degradation. In this study, I tested the hypothesis that miRNAs are differentially expressed in antiestrogen-sensitive MCF-7...
