The Effect Of Age On Social Behaviour In Drosophila Melanogaster And The Progeny Of Aged Parents, Dova Brenman
The Effect Of Age On Social Behaviour In Drosophila Melanogaster And The Progeny Of Aged Parents, Dova Brenman
Electronic Thesis and Dissertation Repository
Recent studies have linked neuropsychiatric disorders to older parents. These disorders often include changes in social behaviours like the social spacing between neighbouring individuals, which can be modeled in organisms such as Drosophila melanogaster. I investigated the effects of aging on the social space between neighbouring D. melanogaster and how aging impacts the next generation. To achieve this, I used the social space assay and found that individuals become less social with age and that this effect is passed on to the first generation only. Additionally, accelerating the physiological process of aging via increased rearing temperatures or exposure to …
Comparative Evolutionary Approach To Pain Perception In Fishes, Culum Brown
Comparative Evolutionary Approach To Pain Perception In Fishes, Culum Brown
Animal Sentience
Arguments against the fact that fish feel pain repeatedly appear even in the face of growing evidence that they do. The standards used to judge pain perception keep moving as the hurdles are repeatedly cleared by novel research findings. There is undoubtedly a vested commercial interest in proving that fish do not feel pain, so the topic has a half-life well past its due date. Key (2016) reiterates previous perspectives on this topic characterised by a black-or-white view that is based on the proposed role of the human cortex in pain perception. I argue that this is incongruent with our …

Contribution Of Trpm2 To Memory Loss In An Alzheimer's Mouse Model, Megan M. Chen
Electronic Thesis and Dissertation Repository
Alzheimer’s disease (AD) is a neurodegenerative disease characterized by the progressive deterioration of memory and other intellectual abilities. Accumulation of amyloid-β (Aβ) peptide, the major contributor to the senile plaques central to AD, is thought to mediate neurotoxicity by inducing oxidative stress and calcium dysregulation. Transient Receptor Potential Melastatin type 2 (TRPM2) is a calcium permeable, non-selective cation channel activated under oxidative stress and ultimately induces cell death. The APPSWE/PSEN1ΔE9 double transgenic mouse model carries the human APPswe (Swedish mutations K594N/M595L) and PS1 mutations with a deletion in exon 9 (PS1-dE9), and is one of the most commonly used AD …
