Comparison Of Longitudinal Changes In Resting State Functional Magnetic Resonance Imaging Between Alzheimer’S And Healthy Controls, Berk Can Yilmaz
Comparison Of Longitudinal Changes In Resting State Functional Magnetic Resonance Imaging Between Alzheimer’S And Healthy Controls, Berk Can Yilmaz
Theses
Resting State Functional Magnetic Resonance Imaging (rs-fMRI) is a technique that is widely used for analyzing brain function using different approaches and methods. This study involves rs-fMRI analysis of Blood Oxygenation Level Dependent (BOLD) signals acquired from Alzheimer’s disease (AD) Patients and Healthy Controls (HC). Each subject in the study had both functional and anatomical images with at least one rs-fMRI scan with their Anatomical (T1) scans. Previous rs-fMRI studies have demonstrated that AD shows differences in Amplitude of Low Frequency (<0.1 Hz) Fluctuations (ALFF), and Regional Homogeneity (ReHo) measures according to HCs.
The aim of the study is to investigate individual and group level differences using ReHo and mALFF related …

Nutraceutical Potential For Alzheimer's Disease Treatment, Alex Gewecke
Undergraduate Research Journal
Alzheimer’s disease (AD) is a progressive disorder involving buildup of excessive amounts of proteins such as beta amyloid in the brain that leads to memory loss, inability to perform daily functions, and an early death. By 2060, the number of cases is forecast to nearly triple current numbers. Age is the primary risk factor for AD and no new drugs have been approved since 2003. Nutraceuticals, a broad category of substances that can be utilized for both medicinal and nutritional purposes may be able to help, which is why they are being more widely researched. Overall, a number of attempts …
Investigation Of The Role Of Heparin-Binding Pocket In Amyloid Fibrils Formation Of Fgf-1, I Gusti Ayu Agung Septiari
Investigation Of The Role Of Heparin-Binding Pocket In Amyloid Fibrils Formation Of Fgf-1, I Gusti Ayu Agung Septiari
Graduate Theses and Dissertations
Human acidic fibroblast growth factor (aFGF/hFGF-1) is one of the promising molecules to be investigated to generate an in-depth understanding of the pathological mechanism of Alzheimer's disease (AD) neurodegenerative disorder characterized by the presence of amyloid fibrils. Some in vivo and human brain tissue studies proved the correlation of high-level expression of FGF-1-induced neuroinflammation and the occurrence of AD. The presence of amyloid fibrils as a hallmark of AD can be related to the generic property of the proteins to form amyloid fibrils; High level of FGF-1, in this case, may contribute to the formation of amyloid fibrils. As a …
Regulation And Function Of Trem2-Dependent Pathways In Neurodegeneration, Wilbur Madison Song
Regulation And Function Of Trem2-Dependent Pathways In Neurodegeneration, Wilbur Madison Song
Arts & Sciences Electronic Theses and Dissertations
Carriers of the R47H allele of the microglia-specific lipid receptor TREM2 have a greatly increased risk of developing Alzheimerճ disease. The objective of this dissertation is to develop further mechanistic knowledge about how TREM2 is regulated and how TREM2 mutations affect microglia and neurodegeneration. Using an in vitro reporter assay, we find that several AD risk-associated TREM2 mutations decrease ligand-dependent activation. Using humanized TREM2 mice, we find that in vivo, the R47H mutation leads to reduced microglia activation and response to A_, as well as decreased shedding of soluble TREM2. These results suggest that TREM2 is protective during disease. We …
A Study Of The Antioxidant Versus Pro-Oxidant Nature Of The Amyloid Beta Peptide And An Analysis Of The Natural Products, Isorhamnetin And Narignenin, As Antioxidants, Kaylee Holmes
Honors Theses
Alzheimer’s disease is a neurodegenerative disorder with no cure. Due to the widespread effects of this disease, abundant research efforts have gone towards finding a cure. The amyloid beta (Ab) peptide has been shown to be a potential cause of the disease due to destructive effects on tissues that it can have both by itself and through reactive oxygen species (ROS) generation. This study was performed in order to assess the structural properties of Ab42monomers, fibrils and oligomers, to assess the antioxidant versus pro-oxidant behavior of the Ab peptide, and to assess the antioxidant nature of the natural …
