Microcirculation: Electrophysiological Basis For The Response Of Endothelial Cells To Inflammatory Mediators-Bradykinin, Kai Miao
Electronic Theses and Dissertations
Using conventional microelectrodes, I studied the electrical basis for determining the resting V$\sb{\rm m}$ in intact EC's from hamsters. The resting V$\sb{\rm m}$ were found to be $-$40 mV for aortic EC's and $-$43 mV for vena caval EC's. The contributions of ions to the resting V$\sb{\rm m}$ of aortic EC's were compared in terms of the transference number (t$\sb{\rm ion}$). To develop a technique for in situ monitoring changes in V$\sb{\rm m}$ of postcapillary venular EC's in the hamster mesentery, a voltage-sensitive fluorescent probe, bisoxonol, was used to load the cells and the fluorescence signals were analyzed under an …
Cytokines And Ovulation In The Mouse Ovary, Jong G. Kim
Cytokines And Ovulation In The Mouse Ovary, Jong G. Kim
Electronic Theses and Dissertations
Ovulation has been hypothesized as an inflammatory process. Interleukin(IL)-1$\alpha$, IL-1$\beta$ and tumor necrosis factor(TNF)-$\alpha$ are potent cytokines produced from macrophages and various other cell types, and are pivotal components of inflammation. Although previous studies have investigated cytokine activities in the reproductive system, there is little information on their precise localization and activities during the periovulatory period. To investigate the role of cytokines in ovulation, experiments were designed to determine the immunohistochemical localization and time specific production of cytokines IL-1 and TNF-$\alpha$ using a mouse model at 36h, 12h, 6h, 2h before ovulation, and at 6h and 18h after ovulation in …

The Formulation, Implementation, And Evaluation Of Educational Planning In Public School Districts Of Tennessee, Daniel R. Fielden
The Formulation, Implementation, And Evaluation Of Educational Planning In Public School Districts Of Tennessee, Daniel R. Fielden
Electronic Theses and Dissertations
The legislature of the State of Tennessee enacted The Public Education Governance Reform Act of 1984 as the first step in a restructuring and reform program for Tennessee education. One of the major elements of this piece of legislation was that the state board of education would "... develop and maintain current a master plan for the development of public education, grades kindergarten (K) through twelve (12)." A regulation was passed by the Tennessee State Board of Education mandating that each local board of education in the state should develop and implement a five-year educational plan to include a mission …
Effect Of Leadership Style On Work Climate And Program Completion In Domiciliary Addiction Programs, Patricia L. Johnson
Effect Of Leadership Style On Work Climate And Program Completion In Domiciliary Addiction Programs, Patricia L. Johnson
Electronic Theses and Dissertations
Addiction leads to homelessness, AIDS, other health problems, crimes, financial burdens, family conflict and many social and psychological problems. Relapse rates remain very high in addiction programs and employees are frustrated by the poor response of clients to treatment and to the bureaucratic style of management often found in hospitals and clinics. Relapse rates are due to stress factors, respondent conditioning processes, and lack of focus on techniques of relapse prevention. One approach to overcoming the morale problem could be a more participatory style of management to improve the work climate. This study was completed in response to the lack …
The Effects Of Caffeine And Affective Imagery On Facial Emg In Women, Robert Francis Mirabella
The Effects Of Caffeine And Affective Imagery On Facial Emg In Women, Robert Francis Mirabella
Electronic Theses and Dissertations
Research findings on the effects of caffeine on mood have been mixed. Some studies report that caffeine increases anxiety and alertness while others do not. The variability in outcome of caffeine studies may be due to the insensitivity of self-report measures. An alternative to self-report is facial EMG which may be superior to self-report since the degree of concordance between facial EMG and affective valence ratings is considerably higher than the degree of concordance between behavioral, self-report, and physiological measures. Typically, studies investigating the effects of caffeine on mood have tested caffeine's effects on idiosyncratic mood states which prevailed in …
Factors Influencing The Oxidation Of Lipoproteins And Plasma Lipids, Yanshan Ma
Factors Influencing The Oxidation Of Lipoproteins And Plasma Lipids, Yanshan Ma
Electronic Theses and Dissertations
The hypothesis that antioxidant vitamins (ascorbate and tocopherols) along with urate protect blood plasma lipids from oxidation was tested. Dietary fat is also an important factor influencing plasma lipid peroxidation. The purpose of this study was to investigate the role of plasma antioxidants and dietary fat on low density lipoprotein (LDL) and plasma lipid oxidation. In the first part of this study, we compared the ability of urate and ascorbate to protect human LDL from in vitro oxidation. LDL oxidation was initiated by 15 mM of a water soluble azo-initiator in the presence or absence of ascorbate or urate. The …

Electronic Theses and Dissertations
Settled on the often disputed border of New England and Acadia during the last quarter of the 17th century, the Baron Jean Vincent de l’Abbadie de St. Castin operated a trading post at the confluence of the Penobscot and Bagaduce Rivers near the modem town of Castin, Maine. Castin was an entrepreneur who traded with the Abenaki Indians of Acadia and Maine for peltry. Although he was French, Castin exchanged this peltry with Massachusetts merchants in order to get the European trade items necessary to supply his Abenaki clientele. Castin preferred trade to warfare, nevertheless, he was often embroiled in …

Faculty and program coordinators ranked their perceptions of their own practice highly. Faculty and program coordinators ranked their perceptions of their …
Role Of The Cd40-Cd40 Ligand Interaction In Cd4(+) T Cell Activation Of Monocyte Interleukin-1 Synthesis, David H. Wagner
Role Of The Cd40-Cd40 Ligand Interaction In Cd4(+) T Cell Activation Of Monocyte Interleukin-1 Synthesis, David H. Wagner
Electronic Theses and Dissertations
Most studies of the induction of cytokine synthesis in monocytes have used an exogenous triggering agent such as Lipolpoysaccharide (LPS). However, during nonseptic chronic inflammatory responses (e.g., rheumatoid arthritis) monocyte activation occurs as a result of T cell generated signals. This report demonstrated that plasma membranes from anti-CD3 activated peripheral CD4$\sp{+}$ T cells (Tm$\sp{\rm A}$) but not from resting CD4$\sp{+}$ cells (Tm$\sp{\rm R}$) induced monocytes to synthesize IL-1 in the absence of costimulatory cytokines. The expression kinetics of the molecule(s) unique to activated T cells which interact with monocyte receptors to induce IL-1 demonstrated that optimal expression occurred at 6h …

The Hydroclimatic Characteristics Of Nacogdoches, Texas With Implications For Water Resources Management, Larry David Clendenen
Electronic Theses and Dissertations
Sayok's (1986) study and statistical analysis of the climate at Nacogdoches, Texas covering 1901 to 1980 is updated to include the most recent twelve years (1981-92) of records. Missing data are estimated, all analyses are repeated, and the new 1961-90 normal climate is compared to the 1951-80 and other normals. Results showed that the climate at Nacogdoches during the last decade was about the same as that in other recent decades. Thomthwaite's (1957) climate classification defines Nacogdoches as moist subhumid, third mesothermal, with moderate summer water deficiency, and a temperature effIciency regime equal to a fourth mesothermal climate. There are …

Denervation Supersensitivity Of The Rat Vas Deferens: A Role For Protein Kinase C, Sonny T. Abraham
Denervation Supersensitivity Of The Rat Vas Deferens: A Role For Protein Kinase C, Sonny T. Abraham
Electronic Theses and Dissertations
A role for protein kinase C (PKC) in the denervation-induced supersensitivity of the rat vas deferens was investigated. Chronic, surgical denervation of the rat vas deferens (up to 8 days) resulted in tissues that produced enhanced contractile responses to norepinephrine (NE) in isolated organ baths. Single challenges of NE (10 $\mu$M) produced 0.6 $\pm$ 0.1 g of maximal tension in the control vas whereas in the paired, denervated tissue 2.2 $\pm$ 0.3 g of tension was recorded (n = 6). Cumulative concentration-effect curves to NE produced in the denervated vas deferens were shifted 18-fold to the left of the control …
