Investigation Of End-tidal Carbon Dioxide (ETCO₂) And Heart Rate Variations During Sleep Apnea
(Biomedical Engineering, 2010-11-01)Sleep Apnea is a sleep disorder where limitation or cessation of breathing occurs. It is characterized by abnormalities in the respiratory pattern and quantity of ventilation during sleep. According to a study 4% of men ... -
INVESTIGATION OF FUNCTIONAL CONNECTIVITY AND NEUROVASCULAR COUPLING IN DIFFERENT VIGILANCE / BREATH-HOLD STATES OF THE BRAIN FROM SIMULTANEOUS EEG-fNIRS MEASUREMENTS
(2019-07-10)Functional connectivity and neurovascular coupling are important phenomena that occur in the brain. Functional connectivity is the study of functional brain networks and their characteristics. While neurovascular coupling ... -
Investigation Of Information Processing And Cognitive Performance Capacities With Different Instrumentation Configurations
(Biomedical Engineering, 2007-08-23)The focus of this thesis is the investigation of two new performance capacity tests related to a concept known as "situational awareness": 1) Visual Motor Multitask Performance Capacity (VMMPC) and 2) Visual Auditory ... -
Investigation Of Nanoparticle Delivery To Cancer Cells By Conjugation With Various Targeting Moieties
Recently, mapping and profiling of specific tumor biomarkers characterizing cancer cells, followed by understanding of signal cascades involved in the pathogenesis of tumors (targeted therapy), as well as diagnosis in early ... -
Investigation Of Neural Correlates Between Perception Of Pain And Hemodynamic Response Measured In The Pre-frontal Cortex Using Functional Near Infra-red Spectroscopy
(Biomedical Engineering, 2011-10-11)Perception of pain is multi-dimensional, comprising three major psychological dimensions: sensory-discriminative, motivational-affective and cognitive-evaluative. This dissertation study investigates the cognitive evaluation ... -
An Investigation Of Peripheral Blood Volume And Oxygen Saturation Change In Obstructive Sleep Apnea
(Biomedical Engineering, 2010-11-01)Obstructive sleep apnea (OSA) is a type of sleep disordered breathing in which the airway collapse partially or fully and causes arousal to resume breathing. In a 2009 National sleep foundation poll of 1000 people, 63% ... -
INVESTIGATION OF PREFRONTAL COGNITION RESPONSES TO TRANSCRANIAL LASER STIMULATION IN PTSD USING FUNCTIONAL NEAR INFRARED SPECTROSCOPY
(2016-05-31)In recent years low level laser therapy (LLLT) has been of great research interest because of its therapeutic applications in psychiatry, neurology and ophthalmology. In-vivo transcranial delivery of LLLT has shown to ... -
An Investigation Of Support Vector Machine Classifier In Detecting Nocturnal Airway Obstruction From Spontaneous Heart Rate Combined With ECG Morphology Changes
(Biomedical Engineering, 2011-10-11)Sleep apnea is a sleep disordered breathing resulting from limitation or cessation to breathing for 10 or more seconds. The prevalence of sleep apnea has increased exponentially in the past decade. The increase in epidemic ... -
An Investigation Of The Covariations Between Variations In Exhaled Carbon Dioxide And Cerebral Blood Flow Levels During Apnea
Sleep apnea is a breathing disorder characterized by repetitive reduction or cessation of breathing during sleep. It is estimated that that around 17% of adults suffer from mild to severe sleep disordered breathing. The ... -
An Investigation Of The Effect Of Obstructive Sleep Apnea On Cerebral Hemodynamics In Relation With Systemic Hemodynamics
Obstructive Sleep Apnea (OSA) is a major sleep disorder affecting approximately 18 million adults in the US. Recent studies have observed cognitive impairments and brain structural changes in OSA subjects where these ... -
Investigations Into Causes Of Failure Of Regenerative Peripheral Nerve Interfaces
All highly selective methods of neural interfacing for mental control of a robotic prosthesis tested to date have exhibited high rates of failure over time. Regenerative peripheral nerve interfaces (RPNIs) may offer the ... -
Involvement Of Mixed Lineage Leukemia And Homeobox Proteins In Dna Damage Recognition And Repair
(Biomedical Engineering, 2014-03-10)Deoxyribonucleic Acid (DNA) molecules are informational molecules, encoding genetic information which is indispensable in the development and functioning of living organisms. DNA encodes for most proteins essential for all ... -
