Biomedical Sciences

The human apolipoprotein ε4 allele (APOE4) has been implicated as one of the strongest genetic risk factors associated with Alzheimer’s disease (AD) and in influencing normal cognitive functioning. Previous studies have demonstrated that mice expressing human apoE4 display deficits in behavioral and neurophysiological outcomes compared to those with apoE3. Ovarian hormones have also been shown to be important in modulating synaptic processes underlying cognitive function, yet little is known about how their effects are influenced by apoE. In the current study, female adult human APOE targeted replacement (TR) mice were utilized to examine the effects of human APOE …

Pillow Talk: The Epigenetic And Physiological Effects Of Sleep Deprivation, Jennifer D. Cotter

Thinking Matters Symposium Archive

Circadian rhythms, or the 24-hour biological cycles of living cells, function as the body’s internal clock. Although circadian rhythms and sleep are very different processes, they are closely related to one another as these cycles play an important role in sleeping and waking patterns. Recent studies have shown that lack of sleep or sleep of poor quality can disrupt circadian rhythms and may actually cause cognitive disorders and memory loss, facilitate false memory production, and even alter gene expression in humans. This literature review is focused on identifying the epigenetic and physiological effects of disruptions and desynchronization in circadian rhythms …

Isoflavones And Alzheimer’S Disease: The Effects Of Soy In Diet, Sara Habib, Asad Ali Khan Afridi, Mohammad Wasay, Romaina Iqbal

Pakistan Journal of Neurological Sciences (PJNS)

Pathologically, Alzheimer’s disease is a result of aggregation of amyloid peptides and protein tau in the brain forming neurofibrillary tangles which are highly toxic to neuronal circuits in the brain. Recent evidences report that apart from aging, estrogen deficiency is one of the risk factors predisposing to the development of Alzheimer’s disease. Isoflavones, also known as phytoestrogens, are metabolized by the body forming compounds that are known to interfere with neurotoxic pathways and through their anti-fibrillization effects they play a role in reducing apoptosis of neurons and glial cells and promote axonal regeneration. Experimental studies on transgenic models with Alzheimer’s …

Current Pathophysiological Concepts In Cerebral Small Vessel Disease., Fred Rincon, Clinton B Wright

Department of Neurology Faculty Papers

The association between cerebral small vessel disease (SVD) - in the form of white matter lesions, infarctions, and hemorrhages - with vascular cognitive impairment (VCI), has mostly been deduced from observational studies. Pathological conditions affecting the small vessels of the brain and leading to SVD have suggested plausible molecular mechanisms involved in vascular damage and their impact on brain function. However, much still needs to be clarified in understanding the pathophysiology of VCI, the role of neurodegenerative processes such as Alzheimer's disease, and the impact of aging itself. In addition, both genetic predispositions and environmental exposures may potentiate the development …
