Factors Affecting Cyp2c9-Mediated Metabolism, James Matthew Hutzler Jan 2001

Factors Affecting Cyp2c9-Mediated Metabolism, James Matthew Hutzler

Graduate Theses, Dissertations, and Problem Reports (ETD)

Cytochrome P450 enzymes can exhibit non-Michaelis-Menten, or atypical kinetics. In particular, dapsone activates CYP2C9-mediated flurbiprofen 4 '-hydroxylation. However, the mechanism of activation of CYP2C9 is poorly understood. The activation of flurbiprofen, naproxen, and piroxicam metabolism by dapsone was investigated, fitting kinetic data to a two-site effector model, indicating that the CYP2C9 active site may have multiple binding regions. In addition the structural requirements for activation of CYP2C9 were explored using structural analogs of dapsone, with results suggesting that a sulfone group between two benzene rings is necessary for activation. CYP2C9 *2(R144C) and *3(I359L) allelic variants and the F114L mutant enzymes …

A Neural Network-Based Sensor Validation Scheme Within Aircraft Control Laws., Brian Michael Stolarik

Graduate Theses, Dissertations, and Problem Reports (ETD)

In 1992 NASA launched its "faster, better, cheaper" initiative to increase the number of missions while decreasing mission cost and time. Accordingly, NASA began supporting research efforts to replace physically redundant systems on board spacecraft with analytically redundant systems. The sensor failure, detection, identification and accommodation (SFDIA) system eliminates physical redundancy by supplying neural network estimations for the pitch, roll, and yaw rate gyros. A Boolean logic scheme utilizes the estimations to detect and identify gyro sensor failures. Additionally, the SFDIA replaces a faulty sensor with its estimate to ensure nominal flight conditions after a sensor failure. The SFDIA was …

Characterization Of The Airway Epithelial Bioelectric Mechanisms Associated With The Effects Of Epithelium-Derived Relaxing Factor In Guinea Pig-Isolated Trachea, Richard Alan Johnston

Graduate Theses, Dissertations, and Problem Reports (ETD)

In response to elevated serosal or mucosal tonicity, guinea-pig tracheal epithelium releases the non-nitric oxide, non-prostanoid, epithelium-derived relaxing factor (EpDRF), which subsequently diffuses to the underlying airway smooth muscle to initiate relaxation. Hypertonicity-induced smooth muscle relaxation via EpDRF involves epithelial Na+ and Cl- channels and is preceded by a depolarization of the transepithelial potential difference (Vms). By utilizing two different experimental systems, this study sought to characterize further the airway epithelial bioelectric mechanisms associated with the effects of EpDRF in guinea-pig isolated trachea.;First, this study attempted to elucidate which epithelial ion channels and/or transporters are involved in the depolarization of …

Dynamic Property Evaluation Of Frother, Yunkai Xia Dec 2000

Dynamic Property Evaluation Of Frother, Yunkai Xia

Graduate Theses, Dissertations, and Problem Reports (ETD)

Fourteen solvents were evaluated through frothing test and laboratory flotation batch tests. A new frothing parameter, initial dynamic froth index (IDFI), is proposed to compare the frothability of solvent. IDFI is derived from initial retention time of froth instead of retention time. IDFI is defined as the limiting slope of the initial retention time versus concentration curves while the concentration approaches zero. IDFI value depends on chemical structure and molecular weight of the solvent. Combined with normalized frothability index (NFI), normalized collapse rate constant (NKc), hydrophilic-lipophilic balance (HLB) and dynamic froth index (DFI), IDFI can be a useful index in …

Increasing Nutrition Knowledge And Food-Related Behavior Practices Among Participants In The "Dining With Diabetes" Program In West Virginia, Amy B. O'Dell Dec 2000

Increasing Nutrition Knowledge And Food-Related Behavior Practices Among Participants In The "Dining With Diabetes" Program In West Virginia, Amy B. O'Dell

Graduate Theses, Dissertations, and Problem Reports (ETD)

Diabetes is a serious disease that effects a large number of West Virginia's population. A study was conducted using 591 diabetic and non-diabetic subjects who attended the "Dining with Diabetes" program. Subjects completed a demographic form, pretest, and posttest. Pearson's correlation and ANOVA were used to determine the effect of a diabetes intervention program on nutrition knowledge, diabetes behaviors, and practices. The results indicated that there was no significant difference in nutrition knowledge between diabetic and non-diabetic subjects. Interaction was noted when subjects were placed into groups based on their pretest score (p < 0.07). The change in score (posttest score-pretest score) was negatively correlated with pretest score (r = -0.75, p < 0.00). Significant association was also noted between nutrition knowledge score and several behavior and diabetic practices. The results conclude that diabetes education programs may significantly affect some behaviors and diabetic practices.

Evaluation Of Survival And Recovery Characteristics Of Bifidobacteria As Indicators Of Fecal Pollution Of Water, John Elmer Ravenscroft Jr. Dec 2000

Evaluation Of Survival And Recovery Characteristics Of Bifidobacteria As Indicators Of Fecal Pollution Of Water, John Elmer Ravenscroft Jr.

Graduate Theses, Dissertations, and Problem Reports (ETD)

The examination of aquatic environments for bacterial indicator organisms has proven to be a useful and well-established practice for the purpose of monitoring microbiological water quality. An ideal indicator of fecal pollution should be present in sufficient density to allow detection, present simultaneous with pathogen(s), incapable of aftergrowth in external aquatic environments, easy to enumerate, and exclusively of fecal origin. Unfortunately, none of the indicator organisms presently in use today meet all of these requirements. Bifidobacteria show promise as indicators of fecal pollution in water with the additional ability of potentially distinguishing between fecal pollution of human and animal origin. …

Breastfeeding Personal Efficacy Beliefs Of Women University Students, Ann Pollard Cleveland Dec 2000

Breastfeeding Personal Efficacy Beliefs Of Women University Students, Ann Pollard Cleveland

Graduate Theses, Dissertations, and Problem Reports (ETD)

Many women do not initiate breastfeeding although breastfeeding promotes their baby's health. Three reasons why women do not breastfeed are women's mental organization, cultural beliefs about breastfeeding, and women's breastfeeding personal efficacy beliefs. The conceptual framework for personal efficacy beliefs is Bandura's social-cognitive theory (1992, 1995, 1997). This dissertation used a new research instrument to examine women university students' breastfeeding personal efficacy beliefs. The instrument was tested by mail survey techniques that resulted in a 70.6% respondent rate. University women's personal efficacy beliefs about breastfeeding factored into five factor subscales. In order of magnitude, the personal efficacy belief factors were …
