Differential Stimulation Of Monocytes To Secrete Secretory Leukocyte Protease Inhibitor By Lipopolysaccharide Of Periodontal Pathogens, Jason Todd Primm

Theses and Dissertations (ETD)

Lipopolysaccharide (LPS), or endotoxin, is the major component of the outer surface of gram-negative bacteria. LPS is a potent activator of cells of the immune and inflammatory systems, including macrophages, monocytes, and endothelial cells, and contributes to systemic changes known as septic shock. Each LPS molecule has three regions: oligosaccharide, core, and lipid A. Oligosaccharide is exposed on the cell surface, and lipid A anchors LPS in the outer membrane. Recent studies from our lab demonstrated that LPS of periodontal pathogens suppresses neutrophil's ability to secrete super oxide ions and also shown it to interfere with neutrophil chemotaxis. These factors …

Likewise, the US mining industry has difficulties controlling hazardous noise and dust exposures in underground mining. Specifically, studies have shown that coal mine longwall shearer operators are routinely exposed to noise levels at 151 percent of the allowable dose and approximately 20 percent exceed regulatory dust levels. An above ground full scale model of the underground shearing operation was developed to test the feasibility of mounting a permanent partial barrier on …

Associations Between Linguapalatal Contact Patterns And Spectral Moments For /S/, Leslie Leatham Bennett

Theses and Dissertations

Both acoustic and palatographic measures have proven to be useful in speech science research. However, it is not known how closely or consistently these two measures are associated with each other. Therefore, this study investigated the association between changes in tongue-to-palate contact patterns and simultaneous changes in acoustic spectral moments for the fricative /s/. Twenty adults were fitted with pseudopalates and repeated VCV nonsense syllables consisting of an initial schwa followed by the target consonant /s/ and ending with one of three corner vowels (/i, ɑ, u/). EPG (electropalatography) data were quantified using three custom numerical indices (s-narrow, s-wide, and …

Preliminary Characterization Of Mitochondrial Atp-Sensitive Potassium Channel (Mitokatp) Activity In Mouse Heart Mitochondria, Venkat Raghav Aachi

Dissertations and Theses

Myocardial ischemia, infarction, heart failure and arrhythmias are the manifestations of coronary artery disease. Reduction of ischemic damage is a major concern of cardiovascular biology research. As per recent studies, the mitochondrial ATP-sensitive potassium channel (mitoK_ATP) opening is believed to play key role in the physiology of cardioprotection, protection against ischemia-reperfusion injury or apoptosis. However, the structural information of mitoK_ATP is not precisely known. Elucidating the structural integrity and functioning of the mitoK_ATP is therefore a major goal of cardiovascular biology research. The known structure and function of the cell ATP-sensitive potassium channel (cellK_ATP) …

Elders With Diabetes: Implications For Depression Screening, Cynthia Clinkingbeard

Boise State University Theses and Dissertations

Diabetes has been concluded to be a global epidemic (Wild, Sicree, Roger, King & Green, 2004). By the year 2030, it is predicted that depression will become the second leading cause of disability worldwide (World Health Organization [WHO], 2007). The relationship between diabetes and depression is likely not casual.

Those with diabetes are twice as likely to develop depression (Eaton, Armenian, Gallo, Pratt & Ford, 1996; Kawakami, Shimizu, Takatsuka, & Ishibashi, 1999). Conversely, diabetes doubles the likelihood of comorbid depression (Anderson, Clouse, Freedland & Lustman, 2001). The intersection of these two devastating diseases is far from benign. Black, Markides and …
