The Effect Of Visfatin And Adiponectin On Metabolic Parameters Of An Animal Model Of Type 2 Diabetes, Thuraya Saeed Ali Alshamisi

Theses

Background: Diabetes mellitus (DM) is one of the most common exocrine disorders affecting more than 6% of the world’s population. The incidence and prevalence of this chronic disease are on the rise in many parts of the world including the Middle East. DM is caused by defective Insulin production, release and/or function. The causes and nature of abnormal insulin metabolism is less than clear. While defective insulin secretion is observed in type 1 diabetes, insulin resistance is predominant in type 2 diabetes, which affects more than 94% of the diabetic patients.

The Influence Of Hydrogen Peroxide On The Static And Fatigue Properties Of Palacos-R Bone Cement, John M. Guerin

Theses

Aseptic loosening is a very costly complication of joint arthroplasty, both in terms of patient quality of life and financially. One potential contributing factor in its development - namely the use of hydrogen peroxide as an effervescent haemostatic agent - was investigated in this study. Clean bone cement samples and samples contaminated with 6% hydrogen peroxide were manufactured and stored either in room air or normal saline prior to testing. Thus four sample types were tested (clean stored wet or dry and contaminated stored wet or dry). Static (tension to failure) and fatigue testing was performed. Analysis was carried out …

The Potential For Gaseous Biofuels In Ireland, Darren Kenneally

Theses

According to the EU Renewables Directive 2009/28/EC, 20% of the energy across Europe needs to be renewable by 2020. This is inclusive of the energy utilised in the transport sector where 10% of this energy needs to be renewable. In order for Ireland to meet the targets set in the Renewables Directive various changes need to be applied. The utilisation of gaseous biofuels produced from the anaerobic digestion of various feedstocks will aid Ireland in meeting this directive.

In this study biodegradable municipal waste (BMW) and energy crops are analysed as potential feedstocks for the production of biomethane. This biomethane …

Phage Lysins - Structure, Genetics And Applications, Jennifer Garry

Theses

Antibiotics are of the utmost importance in the fight against pathogenic bacteria, however, in recent years there has been a continual increase in the development of antibiotic resistance among bacteria. As a result it has become essential to develop new technologies to combat these pathogens. One such technology is the application of phage lysins as antimicrobial agents against pathogenic infections. A promising phage lysin is LysK, a 495 amino-acid protein derived from Staphylococcal Phage K. LysK can lyse a wide range of staphylococcal species including MRSA. It is also capable of killing both live and dead cells increasing its potential …

Biosynthesis Of Exopolysaccharides From Lactic Acid Bacteria And Evaluation Of Their Prebiotic Potential, Colette Ann Forde

Theses

In this study, two strains of lactic acid bacteria (LAB) namely Weissella kimchii F28 and W. confusa MGl were used for the production of exopolysaccharides (EPS) from sucrose. Both strains produced glucan polysaccharides. In the case of W. kimchii F28, the EPS isolation procedure was performed six times, making modifications in order to optimize the yield of EPS. The maximum yield of EPS for this strain was 16 g per litre of culture. In the case of W. confusa MGl, the EPS isolation procedure was followed five times, resulting in a maximum yield of EPS for this strain of 34.4 …

Detection And Molecular Characterization Of Canine Enteric Viruses In Southern Ireland., Susan Mcelligott

Theses

Enteric viruses, such as canine parvovirus (CPV) and canine coronavirus (CCoV), are a major cause of gastroenteritis in dogs. More serious clinical symptoms occur in young pups, or when both of these viruses infect an animal simultaneously. Caliciviruses and rotaviruses can also cause gastroenteritis in dogs, but these viruses, while causing significant problems in other animal species and humans, are considered to be less significant pathogens of canines. However, on occasion, these viruses have been reported to produce severe clinical symptoms such as vomiting, haemorrhagic enteritis and severe dehydration.

Many viral vaccines for canines are formulated using old vaccine viral …

Automated Interpretation Of The Tandem Mass Spectra Of Peptides Using Artificial Neural Networks, Timothy Patrick Manning

Theses

The manual interpretation of mass spectra is a complex and time consuming task. The problem of manually interpreting this data is further exacerbated by the large numbers of mass spectra which can potentially be produced in a single proteoniics experiment. This shows the need for high throughput approaches to the interpretation of mass spectra. Existing automated approaches are however error prone due to the complexity of the task. Accordingly, this thesis discusses and evaluates the application of neural networks to improving the sensitivity, specificity and robustness of current approaches to the automated interpretation of such mass spectral data.

Several neural …

Composition-Structure-Property Relationships In Multicomponent Bioactive Glasses, Sharon Murphy

Theses

Silicate glasses function effectively as bone grafts by stimulating bone regeneration through gene activation. However these materials offer little therapeutic potential for the regeneration of healthy bone in those suffering from metabolic bone diseases such as osteoporosis. Examining the composition-structure-property relationships arising from the incorporation of therapeutic ions such as strontium (Sr) and zinc (Zn) into such glasses in order to allow for healthy bone regeneration and antibacterial efficacy, as well as sodium (Na) to allow for controlled ion release was the objective of this work. Eight calcium-strontium-sodium-zinc-silicate glass compositions were produced, based on incremental additions of Sr and Na. …

Qualitative in-depth interviews were conducted with 5 local population members, 5 adult immigrants and 2 support service staff. This research examined levels of cultural nationalism among local respondents, …

Helping Parents In The Toronto Sda Churches Understand And Deal With The Challenges Of Adolescents And Work Towards A More Harmonious Relationship, Nephtaly Dorzilme

Doctor of Ministry Projects

Problem. Parenting is a process which requests a great deal of flexibility and understanding. Both parents and child are engaged in the human developmental process; in most cases parents reach the midlife crisis more or less at the same time when the child reaches the adolescence phase. In most cases neither the parents nor the adolescent understand what is really happening in their lives. They begin to dislike each other and a conflictual atmosphere exists in the home. This lack of understanding brings about the breakdown in the relation parent adolescent. On the other hand parents usually have certain goals …

Developing A Cross-Generational Life-Transforming Worship Service: An Approach To Involving And Empowering Youth And Young Adults At The San Diego Filipino-American Seventh-Day Adventist Church, Demetrio F. Robles

Doctor of Ministry Projects

The Problem. The worship services at San Diego Fil-Am were traditionally led by the older generations where most of the time the younger generations felt neglected to and left out in the planning and from experiencing a life-transforming worship. For some time, the younger generations sought opportunities to be involved in worship but the traditional practice of worship did not favor it. Advocates for children and young people in the congregation urge separate worship services for the youth and young adults but this is strongly opposed by the majority of leaders and senior members, many of whom hold leadership positions …

A Strategy To Mobilize Seventh-Day Adventists In Lusaka In Response To The Hiv/Aids Crisis, Harrington Simui Akombwa

Doctor of Ministry Projects

Problem

While Zambia is rated the 7th country worst affected by HIV/AIDS worldwide, the Seventh-day Adventist (SDA) Church, an Faith Based Organization (FBO) well respected nationwide for its concern about people’s physical health because of its hospitals and clinics around the nation, is seemingly standing by doing close to nothing. What could be the problem?

Method

To uncover the possible causes of Adventists’ perceived noncommittal stance on the AIDS issue, a survey designed around a descriptive and exploratory social research model utilizing quantitative research techniques for data collection and analysis was conducted.

A Program For Prevention And Intervention Of Compassion Fatigue And Burnout Among Pastors In The Guyana Conference Of Seventh-Day Adventists, David O. Mckenzie

Doctor of Ministry Projects

Problem

The membership of the Guyana Conference of Seventh-day Adventist has surged to over 50,000 over the ten year period, 1997-2006; however, the professional Adventist clergy group has experienced a decrease over the same time period—from thirty-three to twenty-seven ministers (Guyana Conference of SDA Statistics). The ratio of clergy to laity is, thus, 1:1853, where it was previously 1:1039. Consequently, ministers in the Guyana Conference of SDA are likely to become victims of burnout—and its compassion fatigue form—as they encounter the demands of ministry.

Methods and Procedures

Following the case study method of qualitative research, the researcher utilized Eisner’s (1998) …

Development Of An Action Plan To Transform The Erwin Hills Seventh-Day Adventist Church Into A Family-Friendly Church For The Purpose Of Winning Families With Youth And Children, Eli Rojas

Doctor of Ministry Projects

Problem

Through a period of a few years the Erwin Hills Seventh-day Adventist Church went from a thriving congregation with members of all ages to a small group of faithful members who desired to see the return of the days when their church was thriving. As the new pastor took office a desire to change came upon the leadership, one that led them to think of ways to attract and retain families to their ranks. There was a lack in ministry that was inclusive of all the members of a household and thus unattractive to new members with young adults …

The Historical Reflection Of The Integration Of The Minority Groups Within The Adventist Church In Zimbabwe Between 1985 And 1994, Jonathan Tapera Nzuma

Doctor of Ministry Projects

Problem

The integration of minority groups into the mainstream of the Seventh-day Adventist Church in Zimbabwe has been resisted. In the power struggle that ensued, rooted in complex issues of multi-ethnicity and multiculturalism, the church has gone through a schism. Little reflective thought has been given to how this schism may have been avoided and how to address similar issues in the future, as well as seeking to embrace wounded members back into the larger Adventist Church.

The Method

A theological foundation was laid for this project by examining the biblical doctrine of unity in diversity as portrayed in both …
