Influences Of Salvinorin A And Sex Differences On Depressive- And Anxiety-Like Behaviors In A Chronic Mild Stress Paradigm, Sarah Mitchell

Theses

Kappa opioid receptors are colocalized with dopamine receptors and are frequently associated with depression, anxiety, stress, and drug use and abuse. KOR antagonism has widely been considered anti-depressive and anxiolytic in animal models while agonism is pro-depressive and anxiogenic. However, recent findings suggest that SalvA, a natural kappa agonist derived from a plant in the mint family, can reduce depressive- and anxiety-like behavior in rats. The current study investigated the effects of chronic mild stress on behavior, attenuation by SalvA, and sex differences. 52 Long-Evans rats, 26 males and 26 females, were exposed to six weeks of CMS. Animals received …

Nearshore Vertical Distribution Of Barnacle Cyprids: Temporal Patterns And Hydrographic Variability, Gabriela Yamhure

Theses

Most benthic organisms living in the intertidal zone have planktonic larvae that reside temporarily in the water column before settling in their adult habitats. Larvae aggregate in offshore larval pools, and transport horizontally and vertically in the water to remain in the nearshore and during their pelagic life. While some horizontal transport of larvae can be attributed to advection, behavioral responses, like vertical swimming and buoyancy control, allow larvae to position themselves at depths where flow direction can be exploited. Thus, knowledge on how vertical larval distribution relates to physical processes can be fundamental to better understand larval transport. These …

Modulation Of Anti-Microbical Defenses In The Gasrointestinal Tract By Acetylcholinesterase Inhibitors, Alreem Abdulaziz Al-Dhalali Al-Mansori

Theses

Inflammation is a crucial defence mechanism that protects the body from the effect of invading pathogens. However, the inflammatory response needs to be controlled in order to avoid systemic manifestations with serious consequences to the host. Accumulating evidence indicates that the inflammatory response is tightly regulated through immunological and neural pathways. Previously, it has been demonstrated that cholinergic stimulation by paraoxon, a specific and irreversible inhibitor of acetylcholinesterase (AChE), improved survival in mice following oral infection with virulent Salmonella enterica serovar Typhimurium (S. Typhimurium). However, paraoxon is an organophosphorus compound unsuited for human use. In this study, the …

The Spiritual Growth Of Girls In Mercy Secondary Schools In Western Australia: The Perceptions Of Post-School Women., Tania Hicks

Theses

This study provides insight into the spiritual growth of girls in Mercy secondary schools in Western Australia (WA). Student spiritual growth is a fundamental priority in Catholic schools; it predicates the Church’s mission of evangelisation and aids the provision of a holistic education. Spiritual growth also enhances wellbeing through offering protective factors which may equip students in facing contextual challenges. Yet how is student spiritual growth fostered? Scholarly literature calls for further study in spiritual education (de Souza, 2016; King, 2013; Ng, 2012; Wright, 2000) suggesting a need for increased clarity about how to foster the spiritual growth of young …

The Hope And History Debate In Fundamental Theology, David Patrick Collits

Theses

The hope and history debate in twentieth century Catholic theology concerned to what extent the object(s) of eschatological hope could be realised within history. Its context was the ‘secularisation of Christian eschatology’. On the one hand, Joseph Ratzinger, who was indebted to the philosophical work of Josef Pieper, considered hope’s object to belong to the realm of gift. He was sceptical of the extent to which hope could be manufactured by human means within history. On the other, Edward Schillebeeckx, Johann Baptist Metz and Gustavo Gutiérrez presented theologies of futurity, including political theology and liberation theology, in which the realisation …

Effect Of Mptp On Α-Synuclein Spreading, Accumulation And Toxicity In Mice With Intrastriatal Innoculation Of Human Α-Synuclein Preformed Fibril, Madiha Mohieldin Merghani

Theses

Parkinson’s disease (PD) is the second most common progressive neurodegenerative disorder, characterized by abnormal accumulation of interneuronal inclusions of α-synuclein (α-syn) known as Lewy bodies (LBs) and Lewy neurites (LNs), and significant loss of dopamine neurons in the substantia nigra pars compacta (SNc) region of the brain. Recent evidence suggests that intrastriatal inoculation of α-syn Preformed Fibril (PFF) into mice induces PD-like LBs and LNs pathology formed by aggregated α-syn in anatomically interconnected brain regions which needs several months of incubation to develop the pathology. In the present study, we have evaluated the effect of different doses of 1-methyl, 4-phenyl, …

The Use Of Mycobacteriophages As A Novel Therapeutic Option To Control And Treat Johne's Disease, Gillian Catherine Crowley

Theses

The incidences of Johne’s disease (JD) in farms worldwide have increased significantly over the last 80 years. The increase in JD is owing to the lack of diagnostic tests available and the long incubation period of the disease causing pathogen, Mycobacterium avium paratuberculosis (MAP). In addition, treatment of JD with antibiotics has proven difficult due to the emergence of antibiotic resistance MAP strains and the presence of the thick lipid rich mycobacterial cell wall. An alternative diagnostic and treatment method for JD involves the use of mycobacteriophages. As part of this research, individual mycobacteriophages (TM4) and a mycobacteriophage cocktail (LE1 …
