Abstract

Rapid-eye-movement (REM) sleep without atonia (RSWA), a marker of REM sleep behavior disorder (RBD), is frequently comorbid with Parkinson’s disease (PD). Although rodent models are commonly used for studying PD, the neurobiological and behavioral correlates of …

Increased Dementia Mortality In West Virginia Counties With Mountaintop Removal Mining?, A. K. Salm, Michael J. Benson

Faculty & Staff Scholarship

(MTM), a practice that has been ongoing in some counties of West Virginia (WV) USA since the 1970s. PM inhalation has been linked to central nervous system pathophysiology, including cognitive decline and dementia. Here we compared county dementia mortality statistics in MTM vs. non-MTM WV counties over a period spanning 2001–2015. We found significantly elevated age-adjusted vascular or unspecified dementia mortality/100,000 population in WV MTM counties where, after adjusting for socioeconomic variables, dementia mortality was 15.60 (±3.14 Standard Error of the Mean (S.E.M.)) times higher than that of non-MTM counties. Further analyses with satellite imaging data revealed a highly significant …

Venous Manometry As An Adjunct For Diagnosis And Multimodal Management Of Intracranial Hypertension Due To Meningioma Compressing Sigmoid Sinus, Cletus Cheyuo, Charles L. Rosen, Ansaar Rai, Christopher P. Cifarelli, Rabia Qaiser

Faculty & Staff Scholarship

Intracranial venous hypertension is a rare presentation of meningiomas in the transversesigmoid sinus region. We describe a case of a young patient presenting with intracranial hypertension due to a meningioma causing compression of the dominant sigmoid sinus. We were able to document the cerebral venous pressure gradient across the lesion confirming our hypothesis that compression of the sigmoid sinus from the meningioma was the cause of intracranial hypertension. The patient is a 17-year-old male who presented with intracranial hypertension due to meningioma at the right dominant sigmoid sinus, which was treated by a Simpson grade IV surgical resection followed by …

Molecular Mechanisms Of Cancer-Induced Sleep Disruption, William H. Walker, Jeremy C. Borniger

Faculty & Staff Scholarship

Sleep is essential for health. Indeed, poor sleep is consistently linked to the development of systemic disease, including depression, metabolic syndrome, and cognitive impairments. Further evidence has accumulated suggesting the role of sleep in cancer initiation and progression (primarily breast cancer). Indeed, patients with cancer and cancer survivors frequently experience poor sleep, manifesting as insomnia, circadian misalignment, hypersomnia, somnolence syndrome, hot flushes, and nightmares. These problems are associated with a reduction in the patients’ quality of life and increased mortality. Due to the heterogeneity among cancers, treatment regimens, patient populations and lifestyle factors, the etiology of cancer-induced sleep disruption is …

Global Climate Change And Invariable Photoperiods: A Mismatch That Jeopardizes Animal Fitness, William H. Walker Ii, Olga Hecmarie Meléndez‐Fernández, Randy J. Nelson, Russel J. Reiter

Faculty & Staff Scholarship

The Earth's surface temperature is rising, and precipitation patterns throughout the Earth are changing; the source of these shifts is likely anthropogenic in nature. Alterations in temperature and precipitation have obvious direct and indirect ef‐ fects on both plants and animals. Notably, changes in temperature and precipita‐ tion alone can have both advantageous and detrimental consequences depending on the species. Typically, production of offspring is timed to coincide with optimal food availability; thus, individuals of many species display annual rhythms of reproductive function. Because it requires substantial time to establish or re‐establish reproduc‐ tive function, individuals cannot depend on the …

Neurogenesis In Neurodegenerative Diseases: Role Of Mfg-E8, Cletus Cheyuo, Monowar Aziz, Ping Wang

Faculty & Staff Scholarship

Neurodegenerative diseases are devastating medical conditions with no effective treatments. Restoration of impaired neurogenesis represents a promising therapeutic strategy for neurodegenerative diseases. Milk fat globule-epidermal growth factor-factor VIII (MFG-E8) is a secretory glycoprotein that plays a wide range of cellular functions including phagocytosis of apoptotic cells, anti-inflammation, tissue regeneration, and homeostasis. The beneficial role of MFG-E8 has been shown in cerebral ischemia (stroke), neurodegenerative diseases such as Alzheimer’s disease and Parkinson’s disease, and traumatic brain injury. In stroke, MFG-E8 promotes neural stem cell proliferation and their migration toward the ischemic brain tissues. These novel functions of MFG-E8 are primarily mediated …
