Electrochemical Studies Of Some Furyl, Indol, Pyrrol, Hydroxynapthyl And Thienyl Derived Sulfonamides And Their Antibacterial Activities, Raja S. Machana

Theses and Dissertations

Sulfonamides are synthetic, wide-spectrum, antibiotics that find current therapeutic applications in the treatment of urinary tract infections, nocardiosis, and toxoplasmosis. Rapid development of bacterial resistance to this class of antimicrobial agents has obligated the need for synthesis of new sulfonamide derivatives. N 1 substitution with heterocyclic moieties produced variable antibacterial efficacies and their structure activity relationships were fairly established. However, para-amino (the N of which is designated as N 4 ) sulfonamide derivatives are less commonly studied. In this research we have selected a series of para-amino sulfonamide derivatives. Since redox potentials are important in determining the physiological activity of …

The Effect Of 1,25-Dihydroxy Vitamin D3 On At1 Cell Receptor Expression In Human Iliac Artery Endothelial Cells (Hiaec), Jenny Thomas

Theses and Dissertations

The renin-angiotensin system (RAS) plays an important part in homeostasis through angiotensin IPs role as a vasoconstrictor. Defects in the renin angiotensin system can lead to hypertension, heart attack, and stroke (Weir, 1999). Studies have shown an inverse relationship between Vitamin D3 and blood pressure (Li et al., 2002). While studies have been performed on vitamin D's effect on renin expression, little is known about vitamin D's effect on the angiotensin II high-affinity type 1 (ATi) receptor. The hypothesis for this study was that human iliac artery endothelial cells (HIAEC) supplemented with 1,25-dihydroxy vitamin D3 will express less AT] receptor …

Herbal Medications: Implications For The Operating Room, Tricia Marcuson

Theses and Dissertations

US households have an increasing number of people using herbal medications as common self treatments. According to Hodges & Kam (2002), 32-37% of Americans have used herbal medications in the last year. Schmidt (2004) states that 1 in 3 Americans consume herbal products each year. Between 1990 and 1997, the use of herbal medicines increased 380% (Ernst, 2004). The interactions between herbal medications and anesthetic drugs become more important and meaningful due to the wide spread use. There are currently 15 million adults in the United States at risk for a potential adverse interaction with a prescription medication and an …

Developing A Rapid Method For Assessing The Physical Stability Of Streams In Minnesota's Agassiz Beach Ridges, Abigail V. Franklund

Theses and Dissertations

This thesis assessed the physical characteristics and stability of selected western Minnesota streams that cross the eastern beach ridges of glacial Lake Agassiz. Stream and river channels in this area host unusually diverse aquatic habitat and biodiversity, but incompatible land use along channels and in watersheds impair their quality and function. Previous rapid assessment protocols have been developed for stream attributes and stability, but these methods have been developed elsewhere in the United States and are not necessarily appropriate for western Minnesota’s unique geology and landscape.

A rapid reconnaissance method was developed to assess stream conditions using an integrated numerical …

Anesthesia And The Thermal Injury Patient: A Current Literature Review, John Hoscheid

Theses and Dissertations

Problem and Purpose: A major burn is one of the most devastating physiologic and psychologic insults known (McCall & Cahill, 2005). The 2007 American Burn Association fact sheet estimates that each burn center has approximately 200 admissions each year and that the other 5,000 hospitals admit approximately 3 burn injuries on average per year. The recent approach to move some burn care to the rural setting will have a major effect on the rural anesthesia practice. The purpose of this study was to enhance the Nurse Anesthetists ability to care for the burn patient.

Conceptual Framework: This literature review study …

In-Situ And Simultaneous Measurements Of Size And Charge Distributions Of Dust On Mars: Instrumentation And Analysis, Praveen Kumar Srirama

Theses and Dissertations

Martian dust characterization is important for minimizing the effects of abrasion, adhesion, corrosion, and damage to mission hardware, and also to reduce the effect on human health during future robotic and human exploratory missions. Characterizing the particle size and charge on Mars dust will help in the development of techniques for dust mitigation. Presently there is no miniature instrument which is capable of in-situ and real time measurements on Mars. In order to simultaneously analyze the particle size and charge of Mars dust, a Dust Particle Analyzer (DPA) has been developed and tested which is based on a Laser Doppler …

A Comparison Of Flexural Fracture Of Three Different Nickel-Titanium Rotary File Systems, Matthew Warren Lloyd

Theses and Dissertations

The purpose of this study was to compare the number of rotations to failure of three different rotary file systems. ProFile, Sequence, and Liberator files in sizes 25 and 40 with 0.04 taper were divided into groups of five and rotated against a grooved metal block mounted to a Universal testing machine at 31 and 34 degrees. Each file was rotated at 300 rpm until fracture occurred. The number of rotations to fracture were calculated. Use of a three-way ANOVA and Tukey's HSD multiple comparison tests revealed significant differences for the angle of deflection, size, and type of file. An …

The Effect Of Income Level On The Relationship Between The Personal Support Matrix And Sustained Breastfeeding, Sandra Mann Gossler

Theses and Dissertations

The Healthy People 2010 Objectives for the population of the United States include the objective for women to sustain breastfeeding at a higher rate than they are currently.The American Academy of Pediatrics (AAP) now recommends that all infants be fed human milk for the first year of life instead of the previously recommended first six months of life. Breastfeeding initiation rates are rising, but breastfeeding duration rates continue to fall. It was hypothesized that the support system of the women may play a role in the duration of breastfeeding. The purpose of this research study was to investigate the support …

Analysis Of Mouse Eklf/Klf2 E9.5 Double Knockout: Yolk Sac Morphology And Embryonic Erythroid Maturation, Tina Kathy Lung

Theses and Dissertations

Krüppel-like factors (KLFs) are a family of transcription factors with 3 Cys2/His2 zinc fingers that regulate cell differentiation and developmental processes. EKLF is involved in primitive and definitive erythropoiesis; KLF2 is implicated in the development of primitive erythroid and endothelial cells of the vasculature. Using light and electron microscopy, the yolk sacs and dorsal aortae from EKLF/KLF2 double knockout (KO) E9.5 (embryonic day 9.5) were examined to determine whether these KLFs have compensatory functions in morphology of blood cells and vessels. EKLF/KLF2 double KO E9.5 erythroid, endothelial, and mesothelial cells had more severely abnormal morphology than WT and KLF2-/-. Flow …

Identification And Characterization Of Helper Phage Gene Products Involved In Mobilization Of Staphylococcal Pathogenicity Island Sapi1, Sandra Mckenzie Tallent

Theses and Dissertations

Staphylococcal pathogenicity island SaPI1 is excised from genomic DNA and extrachromosomal copies are amplified during the vegetative growth of staphylococcal phage 80α. The amplified genetic element is subsequently encapsidated and transduced at very high frequency. Previous studies have demonstrated that the transducing particles have virions with tails that appear identical to those of helper phage 80α but have smaller capsids, commensurate with the smaller genome of the SaPI (Lindsay et.al., 1998). The morphology of the transducing particles, coupled with the observation that the genomic sequence of SaPIl (GenBank U93688) does not reveal any obvious phage structural proteins, has led to …

Breast And Cervical Cancer Screening In Virginia: The Impact Of Insurance Coverage And The Every Woman's Life Screening Program, Kamila Somayaji

Theses and Dissertations

Background: Screening for breast and cervical cancers is important because early detection increases cancer survival. Since 1991, the U.S. government has helped finance a national early detection program for breast and cervical cancer among uninsured low-income women, known in Virginia (VA) as Every Woman's Life (EWL).Objectives: This study aims to determine whether there are differences in the prevalence of breast and cervical cancer screening based on insurance coverage, assess the prevalence of screening by health district, and evaluate the ability of EWL to effectively reach its target population.Methods: Cross-sectional data from the 2005 Behavioral Risk Factor Surveillance System survey were …

The Relapsing Fever Spirochete, Borrelia Hermsii, And Complement Regulatory Proteins, Kelley M. Hovis

Theses and Dissertations

Borrelia hermsii, the primary etiological agent of tick-borne relapsing fever in North America, binds the complement regulatory protein factor H (FH) as a means of evading opsonophagocytosis and the alternative pathway of complement. The sequence of the gene encoding the FH-binding protein has been determined. The protein is unique to B. hermsii and has been designated FhbA. Analyses of B. hermsii isolates revealed that FhbA is expressed by 24 of the 25 isolates tested. fhbA was demonstrated to be a single genetic locus through pulsed-field gel electrophoresis, restriction digest, and hybridization analyses, and all isolates possessing fhbA carry it on …

Renewing Manchester: A Supportive Life Skills Center For Manchester's Most Underprivileged Residents, Jennifer Lynne Hamilton

Theses and Dissertations

In America today, many people have fallen into sub-standard housing situations. Domestic violence, drug abuse, and lack of educational and employment opportunities are a few of the myriad reasons for this. On average the number of homeless people in the greater Richmond area is 5,200 individuals.1 These are people specifically in need of a re-integration into society.This thesis examines the role that the built environment can play in this process, by providing a sustainable, affordable and flexible site for a program that encourages people to rise above their current state by "recycling" them into better more productive citizens. The intent …

Overbite Correction And Smile Esthetics, Kevin Erick Kelleher

Theses and Dissertations

The purpose of this prospective clinical study was to investigate differences in outcomes from two common treatment modalities used to reduce deep overbite: maxillary incisor intrusion using an intrusion arch and posterior tooth eruption using an anterior bite plate. Pre-treatment, post-overbite correction and post-treatment records were gathered from 32 patients who presented with deep overbite malocclusions to the Virginia Commonwealth University orthodontic clinic. Both groups of patients experienced reductions in overbite and maxillary incisor display as well as maxillary and mandibular incisor proclination and mandibular incisor occlusal movement during treatment. In the intrusion arch group, the center of resistance of …
