Exploring The Structure And Biochemistry Of Oxidation-Mediated Inhibitation Of The Peptidyl-Prolyl Isomerase Pin1, Brendan T. Innes

Electronic Thesis and Dissertation Repository

Pin1 is a phosphorylation-dependent peptidyl-prolyl isomerase that has been shown to be neuroprotective in aging-related neurodegenerative diseases such as Alzheimer's disease (AD). However, it is not active in AD brain, and a recent proteomic screen of Mild Cognitive Impairment (MCI) brain samples revealed that Pin1 is oxidized in the brains of these pre-AD patients. This suggests that this oxidation may be the cause of the loss of the neuroprotective Pin1 function in AD. The Pin1 active site contains a functionally critical cysteine residue (Cys113) with a low predicted pKa, making it highly susceptible to oxidation. We hypothesize that Pin1 is …

Diagnosis, Treatment And Follow-Up In Four Children With Biotinidase Deficiency From Pakistan, Bushra Afroze, Mohammad Wasay

Department of Medicine

Biotinidase deficiency is an inherited disorder in which the vitamin biotin is not recycled. If untreated, affected individuals develop neurological and cutaneous symptoms. Untreated individuals with biotinidase deficiency either succumb to disease or are left with significant morbidity. We describe clinical course and follow-up of 4 children from Pakistan. All 4 presented with classical symptoms of biotinidase deficiency and responded dramatically to oral biotin within days to weeks. Biotinidase deficiency is reported in Pakistani children from different part of world, however; there is no such report from Pakistan. This highlights lack of awareness of biotinidase deficiency among physicians in Pakistan

"Who Would Have Thought, With A Diagnosis Like This, I Would Be Happy?": Portraits Of Perceived Strengths And Resources In Early-Stage Dementia, Jutta Elisabeth Ataie

Dissertations and Theses

This study used photovoice methodology to explore how people with early-stage dementia use their perceived strength and resources to cope with the illness. Purposive sampling was used to recruit participants. Thirteen women and seven men age 57 to 90 (mean 73.4) with MMSE scores ranging from 20 to 28 (mean 25.6) participated in the project. Participants were provided with a disposable camera and invited to take photographs relevant to their well-being. The photographs provided the means for participants to take the lead in dialogue sessions about their coping response.

Grounded theory analysis revealed that initially, early-stage dementia precipitated a disruption …

Statin Discontinuation Among Nursing Home Residents With Advanced Dementia, Jennifer Tjia, Sarah L. Cutrona, Daniel J. Peterson, Becky A. Briesacher

Jennifer Tjia

Background: Statin use in elderly individuals with life-limiting illness such as advanced dementia is controversial.

Objective: To describe factors associated with statin discontinuation and estimate impact of discontinuation on 28-day hospitalizations in nursing home (NH) residents with advanced dementia.

Methods: Retrospective cohort study of NH residents ≥ 65 years with recent progression to advanced dementia from 5 large U.S. states drawn from the 2007-2008 Minimum Data Set 2.0. We identified residents using statins. Clinical characteristics and 28-day hospitalization risk were compared for residents discontinuing and continuing statins. Multivariable Cox proportional hazard models identified factors associated with time to statin discontinuation …

Magnetic Resonance Imaging Of Iron In Early Multiple Sclerosis At 3 Tesla, Matthew P. Quinn

Electronic Thesis and Dissertation Repository

Multiple sclerosis (MS) is the most common neurological disease in young Canadians, yet its etiology remains obscure. Two possibly related findings in MS are brain iron deposition and the presence of small veins in white matter lesions. This thesis concerns the development and application of 3 Tesla magnetic resonance imaging tools to image iron and veins in early multiple sclerosis.

To facilitate measurements of iron concentration as well as production of cerebral venograms, we first optimized multi-echo susceptibility weighted imaging (SWI), using numerical simulations and input from physicians. We validated measurements of R2*, an MRI parameter that scales linearly with …

Exploring The Iranian-Canadian Family Experience Of Dementia Caregiving: A Phenomenological Study, Sevil Deljavan

Electronic Thesis and Dissertation Repository

Presently in Canada, there are approximately 500,000 individuals living with dementia, which is expected to increase to over one million by 2038. With Canada’s minority elderly population growing, the number of Iranian-Canadian older adults living with dementia is expected to rise as well. Family caregivers are a significant source of help among Iranian-Canadians and the provision of informal care by adult children for parents with dementia in the Iranian culture is an expression of love and dedication.

This study explored the meaning of the experience of Iranian adult children in Canada caring for a parent with Alzheimer’s disease, the values …

Amyloid Beta Resistance And The Warburg Effect: Re-Examining Alzheimer's Disease, Jordan Taylor Newington

Electronic Thesis and Dissertation Repository

Alzheimer’s disease (AD) is characterized by deposition of the amyloid beta (Ab) peptide in the brain, an event which frequently but not universally correlates with nerve cell death. Although most nerve cells die in response to Ab, small populations of cells are able to survive by becoming resistant to Ab toxicity. Understanding the mechanisms by which cells become resistant to Ab may reveal novel treatments for AD. Interestingly, nerve cell lines selected for resistance against Ab exhibit increased glucose uptake and glycolytic flux. Here I show that these metabolic changes are mediated through an upregulation of pyruvate dehydrogenase kinase 1 …

Diabetes Mellitus And Hypercholesterolemia Are Risk Factors For Alzheimer’S Disease And Appear To Affect The Integrity Of The Blood Brain Barrier, Jacqueline Dash

Graduate School of Biomedical Sciences Theses and Dissertations

Studies have shown that the vascular risk factors common to diabetes mellitus and hypercholesterolemia are also risk factors for Alzheimer’s disease (AD). It is currently unknown how these diseases are associated with AD, but they may cause a leak in the blood brain barrier (BBB), which is one of the hallmarks of AD. In this preliminary study, over 150 pig brain slides were tested for the expression levels of tight junction proteins occludin and claudin V in the BBB microvasculature. There were three groups of pig brains used in this study namely, control pigs, pigs with diabetes mellitus and hypercholesterolemia …

A Descriptive Study To Find Possible Correlation Between Mri Findings Of Pituitary Gland And Serum Prolactin Level, Muhammad Azeemuddin, Rohana Naqi, Mohammad Wasay

Department of Medicine

Objective: To explore equation, if any, between findings of magnetic resonance imaging of pituitary gland and serum prolactin level.

Methods: The retrospective, descriptive study was conducted at the Department of Radiology, Aga Khan University Hospital, Karachi, and related to patients\' records from April 19, 2006 to April 23, 2009. Seventy patients underwent magnetic resonance imaging of brain for pituitary gland. Inclusion criteria were all patients referred with relevant clinical symptoms or deranged serum prolactin level.

Expression Of The Chemokine Receptor, Cxcr4, And Its Ligand, Sdf-1, Are Increased In Purkinje Cells Of The Multiple System Atrophy Cerebellum, Megan Welter

Masters Theses

Multiple System Atrophy (MSA) is a sporadic, neurodegenerative disease that consists of three conditions: autonomic dysfunction, Parkinsonism and cerebellar ataxia. Our lab conducted an Affymetrix global gene expression analysis using pons tissue of MSA patients to determine genes that are differentially expressed when compared to non- MSA controls. This study identified upregulated genes, including the C-X-C chemokine receptor type 4, CXCR4, to which stromal cell-derived factor-I (SDF-1) is the natural ligand. The CXCR4/SDF-1 signaling pair has been sho.wn to play multiple roles in the brain, such as inducing neuronal apoptosis and promoting leukocyte recruitment during inflammation. The MSA cerebellum presents …
