Identification Of The Interaction And Co-Localization Of Leishmania Adenine Nucleotide Translocase With Tor, Rania Elsabrouty
Identification Of The Interaction And Co-Localization Of Leishmania Adenine Nucleotide Translocase With Tor, Rania Elsabrouty
Theses and Dissertations
Leishmania species are parasitic protozoa of the order Kinetoplastida that cause leishmaniasis. Treatment of leishmaniasis with antimonials is difficult and resistance is increasing. Alternative compounds have been investigated, one group is the toxic purine analogs. Resistance to purine analogs, potential anti-Leishmania agents, is brought about by TOR (TOxic nucleoside Resistance protein). TOR is an atypical, multidrug resistance protein that was originally discovered in Leishmania. It renders the cells less sensitive to toxic nucleosides by curtailing the ability of the nucleoside permeases to transport purines across the plasma membrane. Targets of TOR (TOT's) are proteins inside Leishmania that interact with and/or …
The Roles Of Lcrg And Lcrv In Secretion Control Of Yops In Yersinia Pestis, Mohamad Hamad
The Roles Of Lcrg And Lcrv In Secretion Control Of Yops In Yersinia Pestis, Mohamad Hamad
Theses and Dissertations
Yersinia pestis, the causative agent of plague, combats the host immune response by injecting proteins called Yops "Yersinia outer proteins" into the eukaryotic host cells using a type III secretion system "T3SS". The activity of the type T3SS is regulated by several proteins including YscF, YopN, TyeA, SycN, YscB, LcrG, and LcrV. YscF forms the extracellular needle complex of the T3SS and is involved in secretion regulation and in sensing environmental signals for secretion activation. YopN, TyeA, SycN, and YscB form a complex in the cytosol of Y. pestis that blocks the secretion of Yops when conditions do not favor …
Maternal Psychiatric Disturbance At Eight Weeks Postpartum And Its Relation To Personal, Child, And Family Functioning At Two To Three Years Postpartum, Erin N. Haugen
Theses and Dissertations
A large body of evidence suggests interpersonal environments of women with postpartum depression are impaired. However, it is unclear whether postpartum anxiety is associated with similar psychosocial impairment, particularly relating to parental and relationship functioning. Many studies examining postpartum anxiety have been cross-sectional in nature rendering it difficult to make long-term predictions about functioning of anxious mothers and their families. The present study was one of few longitudinal studies examining the relation between postpartum anxiety and long-term psychosocial functioning. Mothers reporting significant anxiety (n = 20) and mothers denying significant anxiety and depression (i.e., control mothers; n = 35) at …
Volunteerism And Marital Quality Among Lds Senior Missionary Couples, Megan Oka
Volunteerism And Marital Quality Among Lds Senior Missionary Couples, Megan Oka
Theses and Dissertations
Although research has been conducted on marriage and volunteerism in later life, little is known about the impact of volunteerism on marital quality, particularly intense volunteer experiences. Missionary couples for the Church of Jesus Christ of Latter-day Saints (LDS) leave their homes for a period ranging from 6-18 months and dedicate the majority of their time to working in church assignments. Qualitative interviews were collected from couples who had served senior couples missions for the LDS Church and returned home in the last year. The mean age of participants was 69, and the mean length of marriage for couples was …
Authentic Out-Of-Class Communication In Study Abroad Programs: Success Defined By Continued Motivation And Cultural Appreciation, Erin Fairlight Olsen
Authentic Out-Of-Class Communication In Study Abroad Programs: Success Defined By Continued Motivation And Cultural Appreciation, Erin Fairlight Olsen
Theses and Dissertations
The benefits of study abroad experience in second language acquisition have evolved from unchallenged assumption to the focus of rigorous study in the past several decades. The benefits of out-of-class contact with natives have likewise been questioned. Despite conflicting evidence of its benefit, students frequently cite out-of-class conversations with natives as among the most beneficial aspects of their language acquisition experience. Reviewing the extant literature, this study narrows in on authentic communication-that is, meaningful out-of-class contact with natives, in which students are able to genuinely express themselves and their personality-as a previously unanalyzed element of study abroad research. It is …
Differential Response Of Various Spore Species To Sporicidal Disinfectants, Michael David Pratt
Differential Response Of Various Spore Species To Sporicidal Disinfectants, Michael David Pratt
Theses and Dissertations
In the fall of 2001, letters laced with anthrax spores were delivered to various news organizations in New York and Florida, as well as to two Senators in Washington, D.C. Over 22 anthrax infections and five deaths resulted from exposure to these spores, and decontamination of the affected buildings was both time consuming and costly. Since these attacks, interest in sporicidal disinfectants has increased greatly. Many chemical sporicidal disinfectants are available commercially, but the exposure time required to sterilize can be relatively long. In addition, some spores are simply injured or inhibited by chemical disinfectants, but not necessarily killed. Studies …
Validity And Reliability Of Dynamic Virtual Interactive Design Methodology, Renran Tian
Validity And Reliability Of Dynamic Virtual Interactive Design Methodology, Renran Tian
Theses and Dissertations
This study focuses on testing the validity and reliability of dynamic Virtual Interactive Design (VID) methodology with dynamic ergonomics analysis. Virtual Interactive Design methodology has been introduced and applied on practical problems in several previous studies, and initially validated with posture-based static ergonomics analysis tools. Although most results have proved the validity and reliability based on static information considered, such validation processes is not sufficient since risks for performing certain tasks can not be fully examined without examining dynamic aspects. But the dynamic virtual interactive design environment has not been validated sufficiently. In my subsequent study, a dynamic ergonomics analysis …

Egocentric Depth Perception In Optical See-Through Augmented Reality, James Adam Jones
Egocentric Depth Perception In Optical See-Through Augmented Reality, James Adam Jones
Theses and Dissertations
Augmented Reality (AR) is a method of mixing computer-generated graphics with real-world environments. In AR, observers retain the ability to see their physical surroundings while additional (augmented) information is depicted as simulated graphical objects matched to the real-world view. In the following experiments, optical see-through head-mounted displays (HMDs) were used to present observers with both Augmented and Virtual Reality environments. Observers were presented with varied real, virtual, and combined stimuli with and without the addition of motion parallax. The apparent locations of the stimuli were then measured using quantitative methods of egocentric depth judgment. The data collected from these experiments …
An Investigation Of Mexican Immigration In Itawamba And Tishomingo Counties, Northeast Mississippi, Anna Elizabeth Pounders
An Investigation Of Mexican Immigration In Itawamba And Tishomingo Counties, Northeast Mississippi, Anna Elizabeth Pounders
Theses and Dissertations
The purpose of the research presented the spatial and demographic patterns of Mexican immigrants in Itawamba and Tishomingo Counties, which are located in northeast Mississippi. The migration patterns and migrant demographics have not been previously investigated in this region. Interviews in Spanish were given to all willing Mexican migrant participants during the summer of 2006. Source regions of the northeast Mississippi migrants are substantially different from the migrant populations elsewhere in the United States. The majority (60%) of the participants are from Veracruz, Mexico rather than the traditional west-central Mexico as seen elsewhere in the United States. Most immigrants (61%) …
The Effect Of Pasteurization Temperature On Consumer Acceptability, Sensory Characteristics, Volatile Compound Composition, And Shelf-Life Of Fluid Milk, April Lynne Gandy
The Effect Of Pasteurization Temperature On Consumer Acceptability, Sensory Characteristics, Volatile Compound Composition, And Shelf-Life Of Fluid Milk, April Lynne Gandy
Theses and Dissertations
The relationship among consumer acceptability, descriptive sensory attributes, and shelf-life was determined for 2 % milk pasteurized at 77, 79, 82, or 85?aC. Pasteurization temperature had no effect (p>0.05) on shelf-life. Consumers preferred (p<0.05) 79?aC over other treatments on day 0; however, six days post-pasteurization 79?aC milk was only preferred (p<0.05) over 77?aC. Consumers were grouped into eight clusters based on product liking for both day 0 and 6 evaluations. The largest cluster liked all pasteurization treatments, and 79?aC was highly acceptable to all consumers that liked milk. Similar sensory descriptors indicated the end of shelf-life for all pasteurization treatments even though treatments could be differentiated by descriptors on day 0. This research reveals that altering pasteurization temperature from 79?aC may cause a decrease in consumer acceptability to some consumers. Altering pasteurization temperature does not affect shelf-life or sensory descriptors and volatile compound profiles at the end of shelf-life.
The Implementation Of Drug Court Progams In Selected States: An Examination Of Government Influence, Lisa Ann Nored
The Implementation Of Drug Court Progams In Selected States: An Examination Of Government Influence, Lisa Ann Nored
Theses and Dissertations
With the merger of judicial supervision and mandated treatment, drug courts have given rise to therapeutic jurisprudence and attempt to address those issues which have plagued corrections policymakers for several decades. The evaluation literature indicates that drug courts tend to produce lower recidivism rates, increased retention rates and lower costs when compared to traditional programs. However, as drug courts approach their second decade, there is a void in the literature regarding the implementation of drug court programs. This study specifically examined those factors which either facilitate or challenge the implementation of drug court programs. This study examined implementation issues from …
The Influence Of Probiotic Lactobacilli On Glucose Uptake By Caco-2 Cells, Arun Kumar Rooj
The Influence Of Probiotic Lactobacilli On Glucose Uptake By Caco-2 Cells, Arun Kumar Rooj
Theses and Dissertations
The resident microbes of human gastrointestinal tract cause both harmful and beneficial effects and these effects can be modulated by the administration of beneficial probiotic bacteria. Probiotics attribute several therapeutic and preventive beneficial effects, for both humans and animals. Despite the good effects of probiotic bacteria, the role of probiotic bacteria or their metabolites on the nutrient uptake by enterocytes is very less known. Most studies describe the genomic effects of probiotic bacteria on the transport properties. This thesis describes the short term (10 min or less) non-genomic effects of probiotic bacteria on the glucose uptake by human enterocytes like …

The intestinal microflora from broilers and layers were analyzed for bacterial populations during stress and when supplemented with ascorbic acid. In both studies, stress response was induced by adrenocorticotropic hormone (ACTH) via a mini osmotic pump for 7 days, and intestinal samples were collected before and after stress …
The Role Of A Non-Microtubule-Based Spindle Matrix In Eukaryotic Cellular Division, Melissa Gwen Chambers
The Role Of A Non-Microtubule-Based Spindle Matrix In Eukaryotic Cellular Division, Melissa Gwen Chambers
Theses and Dissertations
A non-microtubule-based spindle matrix has been observed in Drosophila melanogaster meiotic and somatic cells. This matrix comprises the proteins: Skeletor, Megator and Chromator, which localize to the nuclear periphery and chromosomes at prophase and to the microtubule spindle during mitosis and meiosis. This matrix might play a role in nuclear organization and microtubule assembly and stabilization. It is important to determine the presence or absence of this matrix in other species in order to compare form and function to that in Drosophila. These matrix proteins were studied in both normally dividing cells and cells in which division was disrupted. Our …

Understanding The Nifm Dependence Of Nifh In Azotobacter Vinelandii: Functional Substitution Of Nifh By A Nifh-Chll Chimeric Construct In A Nifm- Strain, Kelvin Harris Jr
Theses and Dissertations
The enzyme nitrogenase catalyzes the energy-dependent reduction of dinitrogen to ammonia via biological nitrogen fixation. Nitrogenase is composed of two metalloproteins known as the molybdenum-iron (MoFe) protein and the iron (Fe) protein. The Fe protein, a 60-kDa dimer of the product of the nifH gene, contains a single 4Fe-4S cluster and two Mg-ATP-binding sites, one at each subunit. The Fe protein is the obligate electron donor to the MoFe protein. To date, no other mutual protein has shown to substitute Fe protein in biological fixation, and the NifH is functional only in the presence of the nifessory protein NifM. Interestingly, …

Continuous Simulation Of Groundwater Use And Effluent Discharge In Catfish (Ictalurus Punctatus) Ponds At Five Locations In The Southeast U.S, Sugeng Triyono
Continuous Simulation Of Groundwater Use And Effluent Discharge In Catfish (Ictalurus Punctatus) Ponds At Five Locations In The Southeast U.S, Sugeng Triyono
Theses and Dissertations
Long-term climatological data were used to evaluate the effectiveness of a drop/add management strategy to reduce groundwater use and effluent discharge in catfish ponds in the southeast U.S.. A drop/add approach is based on the creation of a storage volume in the pond for rainfall collection. The storage volume is created by allowing water level in the pond to decrease until some minimum level is reached. When the minimum level is reached, the pond is partly refilled, leaving the remaining volume available to capture incident precipitation. In this way, the role of precipitation in the water budget is increased. In …
Sexual Harassment Of Women In The United States Military: Juror Decisions Of Reserve Officer Training Corps (Rotc) And Civilian College Students, Catherine Michelle Snell
Sexual Harassment Of Women In The United States Military: Juror Decisions Of Reserve Officer Training Corps (Rotc) And Civilian College Students, Catherine Michelle Snell
Theses and Dissertations
The present research examined the influence of military status, organizational climate type, gender, and attitudes toward sexual harassment on juror decisions in a sexual harassment trial. Military participants rated themselves as having more stereotypical masculine characteristics and they rated sexual harassment allegations more seriously. The permissive climate type elicited less serious allegation ratings. Females rated all climates as more permissive, found the defendant more liable, and chose more severe punishments. Tolerant attitudes toward sexual harassment predicted juror decisions for both ROTC and civilian mock jurors. The results highlight the need for further education about sexual harassment to reduce tolerant attitudes …
Tafoni Caves In Quaternary Carbonate Eolianites: Examples From The Bahamas, Athena Marie Owen
Tafoni Caves In Quaternary Carbonate Eolianites: Examples From The Bahamas, Athena Marie Owen
Theses and Dissertations
Tafoni have been confusingly defined in many ways: variations in size, rock type, and forming mechanisms. This study addresses tafoni in Quaternary eolian carbonates to help better define the term. Large tafoni were differentiated from other coastal caves in the Bahamas, specifically flank margin and sea caves, using morphometric analyses. The differentiation is important as all three cave types form in the same area, but flank margin and sea caves can be used as paleo-sea level indicators, while tafoni cannot. Small tafoni show a growth rate of 0.022 m3/yr; and may amalgmate to form larger tafoni, which grew at 0.65 …
