Chlamydia trachomatis is an obligate intracellular pathogen that utilizes a type III secretion system to enter mammalian cells and establish an intracellular niche. TARP, the translocated actin recruitment protein, is a chlamydial invasion protein...
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...
Drug resistance in microorganisms; Salmonella typhimurium
Salmonella enterica serovar Typhimurium is an enteric pathogen capable of infecting
a wide range of hosts. The manner in which this pathogen is able to interact with its
host is difficult to define, as is the case with most microbes. Through the...
Protein C (PC) is an important anticoagulant, antithrombotic, and antiinflammatory in blood plasma. PC deficiency can lead to severe venous thrombotic events, including lung embolism, stroke, and heart attack. In the body, PC is activated only when...
Background: Helicobacter pylori (Hp) establishes life-long gastric infection in billions of humans, and is often responsible for diseases such as peptic ulcer and gastric cancer. Cumulative actions of genetic drift and natural selection over...
Mycobacterium tuberculosis causes the often-fatal infectious disease Tuberculosis, and infects approximately one third of the world's population. Gaining a better understanding of how these bacteria regulate gene expression for intracellular...
Background: When rat salivary gland cells are cultured in vitro, they dedifferentiate within 24 h. Hypothesis: Growth factors will prevent de-differentiation of primary cultures of parotid gland cells, and they will induce differentiation of ParC5...
Chronic periodontitis is strongly associated with composition of the oral biofilm
occupying the gingival crevicular aspect of the tooth and its associated root. Some gram-negative,
"red complex" bacteria instigate periodontal bone loss in...
The objective of my dissertation research was to determine the role of chemical signals in conveying information regarding an individual's health status and suitability as a mate in humans and to examine the role that commensal microflora play in...
Alcohol; Distillation; Alcoholic beverages; Corn--Utilization; Whiskey industry
In the whisky industry there is a balance between the desire to adhere to the traditional production process and the desire to increase profit margins. One solution that follows both stipulations is to increase the alcohol yield of a given batch of...
For more than a hundred million years, male plethodontid salamanders have
utilized non-volatile, proteinaceous courtship pheromones to regulate female mating
receptivity and promote mating success. These pheromones - which are delivered...
Periodontitis is a chronic, destructive inflammatory disease of the supporting
tissues of the teeth with a high prevalence among adults. While the complete
pathogenesis of periodontitis remains unclear, it is initiated and sustained by...
Periodontitis; Iron--Health aspects; Iron in the body
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,...
Mosquitoes as carriers of disease; Dengue viruses; Mosquitoes--Physiology
In the course of their life cycle, mosquitoes undergo an ontogenetic niche shift; immature larval development occurs within an aquatic habitat from which adult mosquitoes subsequently disperse into the terrestrial environment. While adult female...
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...
This thesis begins by reviewing human N-acetyltransferases (Chapter I), then outlines experiments involving human hepatocytes and rat N-acetyltransferases (Chapters II-V). These experiments facilitated the development of a dissertation project...
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 Louisville Leader was an African-American newspaper published from 1917 to 1950 by I. Willis Cole in Louisville, Kentucky. There is a tear down the center of each page of this issue and there are various portions missing or that are illegible...
The Louisville Leader was an African-American newspaper published from 1917 to 1950 by I. Willis Cole in Louisville, Kentucky. Page seven of this issue is very faded.
The Louisville Leader was an African-American newspaper published from 1917 to 1950 by I. Willis Cole in Louisville, Kentucky. This should be Vol. 12. but the masthead was set back to Vol. 10. earlier in the year and the mistake was never corrected.
