Quantitative Mri Correlates Of Hippocampal And Neocortical Pathology In Intractable Temporal Lobe Epilepsy, Maged Goubran Oct 2014

Quantitative Mri Correlates Of Hippocampal And Neocortical Pathology In Intractable Temporal Lobe Epilepsy, Maged Goubran

Electronic Thesis and Dissertation Repository

Intractable or drug-resistant epilepsy occurs in over 30% of epilepsy patients, with many of these patients undergoing surgical excision of the affected brain region to achieve seizure control. Advances in MRI have the potential to improve surgical treatment of epilepsy through improved identification and delineation of lesions. However, validation is currently needed to investigate histopathological correlates of these new imaging techniques. The purpose of this work is to investigate histopathological correlates of quantitative relaxometry and DTI from hippocampal and neocortical specimens of intractable TLE patients. To achieve this goal I developed and evaluated a pipeline for histology to in-vivo MRI …


Early-Onset Familial Alzheimer Disease, Laura J. Murphy Oct 2014

Early-Onset Familial Alzheimer Disease, Laura J. Murphy

Nursing Student Class Projects (Formerly MSN)

An Alzheimer’s diagnosis is an overwhelming and devastating diagnosis for both patients and families. Now imagine if this diagnosis was made at age 55. Instead of looking forward to retirement and grandchildren, these people are preparing for a debilitating disease that will rob them of their memory, cognitive and functional abilities. Early-onset familial Alzheimer’s disease (EOFAD) affects people before the age of 65. Although extremely rare, some exhibit symptoms as early as in their 30s. One of the things most frustrating about this disease is so little is known about its cause. That and the fact there is no cure. …


Tension Pneumocephalus, Nicole Liebner Oct 2014

Tension Pneumocephalus, Nicole Liebner

Nursing Student Class Projects (Formerly MSN)

Pneumocephalus is defined as the presence of air within the cranial vault; tension pneumocephalus occurs when air within the cranial vault becomes trapped and causes a mass effect or increased pressure, damaging the brain (Patel, Idicula, Carrau, & Prevedello, 2013). Small amounts of air within the cranial vault can be reabsorbed or metabolized by the body over a few days without causing symptoms, however, in tension pneumocephalus the air cannot escape, causing extensive neurological symptoms (Webber-Jones ,2005). Thus, asymptomatic pneumocephalus can be a common finding following a cranial surgery, where as tension pneumocephalus is extremely rare (Webber-Jones, 2005). Markam (1967) …


Understanding The Mystery Of Brain Death, Natalie A. Felter Oct 2014

Understanding The Mystery Of Brain Death, Natalie A. Felter

Nursing Student Class Projects (Formerly MSN)

Lack of understanding of brain death has contributed to recent controversial cases (Copnell, 2014). The cases of Jahi McMath and Marlise Munoz were the focus of national news, causing an intense debate among the public and healthcare professionals (Copnell, 2014). The concept of brain death is a mystery to the public (Powell, 2014). Copnell (2014) found that 60% of family members who had been told their loved one was brain dead believed that they were still alive. Health professionals not having a clear grasp of brain death’s definition and assessment can lead to increased confusion in family members (Powell, 2014).


Role Of Astrocyte Network In Edema After Juvenile Traumatic Brain Injury, Andrew Minoru Fukuda Sep 2014

Role Of Astrocyte Network In Edema After Juvenile Traumatic Brain Injury, Andrew Minoru Fukuda

Loma Linda University Electronic Theses, Dissertations & Projects

Juvenile traumatic brain injury (jTBI) is the leading cause of death and disability in young children and adolescents. Despite its lasting detrimental effects on the developing brain, no pharmacological treatment exists. One of the pathological hallmarks of jTBI is edema. Astrocytes play a key role in the edema process, and have been hypothesized that numerous astrocyte networks allow communication and propagation of edema and secondary injury spread. Two key astrocyte proteins are hypothesized to have a central role in the edema process: Aquaporin 4 (AQP4) and Connexin 43 (Cx43). AQP4 is expressed extensively in astrocyte endfeet, which surrounds the blood …

Pillow Talk: The Epigenetic And Physiological Effects Of Sleep Deprivation, Jennifer D. Cotter Apr 2014

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 …
