Estimating Affective States In Virtual Reality Environments Using The Electroencephalogram, Meghan R. Kumar

Theses and Dissertations

Recent interest in high-performance virtual reality (VR) headsets has motivated research efforts to increase the user's sense of immersion via feedback of physiological measures. This work presents the use of electroencephalographic (EEG) measurements during observation of immersive VR videos to estimate the user's affective state. The EEG of 30 participants were recorded as each passively viewed a series of one minute immersive VR video clips and subjectively rated their level of valence, arousal, dominance, and liking. Correlates between EEG spectral bands and the subjective ratings were analyzed to identify statistically significant frequencies and electrode locations across participants. Model feasibility and …

Caloric restriction (CR) is a strategy that attenuates aging in multiple nonhuman species. The Comprehensive Assessment of Long-term Effects of Reducing Intake of Energy (CALERIE) trials are part of a research program aiming to test the effects of CR on aging and longevity biomarkers in humans. Building on CALERIE phase 1, CALERIE phase 2 (CALERIE 2) was the largest study to date to assess sustained CR in healthy humans without obesity. In a 24-month randomized controlled trial comprising 218 participants at baseline, CALERIE 2 showed that moderate CR, 11.9% on average, induced improvements in aging-related biomarkers without adversely affecting psychological …

Adipose Depot-Specific Effects Of 16 Weeks Of Pioglitazone On In Vivo Adipogenesis In Women With Obesity: A Randomised Controlled Trial, Ursula White, Mark D. Fitch, Robbie A. Beyl, Marc K. Hellerstein, Eric Ravussin

Clinical Research Faculty Publications

Aims/hypothesis: In vitro and rodent studies suggest that pioglitazone, a thiazolidinedione, can promote adipogenesis in adipose tissue (AT); however, there is a lack of in vivo studies in humans to support these findings. The objectives of this randomised, placebo-controlled, parallel-arm trial were to test if pioglitazone stimulates in vivo adipogenesis in the subcutaneous adipose tissue depots and if these measures were related to metabolic health outcomes in women with obesity. Methods: Forty-one healthy women with obesity (20 black; 21 white; 29 ± 6 years; BMI 32.0 ± 1.7 kg/m2; 44.0 ± 3.6% body fat) were randomised to consume 30 mg/day …

Study On The Human Gut Bacteria Under Different Ecological Conditions: Antibiotic Perturbation And Dietary Quercetin, Shruti Shashidharan Menon

Electronic Theses and Dissertations

The human intestine encompasses a vast community of microorganisms known as the gut microbiota that play a crucial role in maintaining health. Common perturbations such as changes in the normal diet, antibiotic treatment, and changes in environmental conditions can alter the gut microbiome. This can create dysbiosis in the gut leading to disease conditions. Therefore, it becomes important to determine the forces that influence the gut microbial ecology. In the first study, we focus on antibiotic perturbations on microbial succession and resilience in a synthetic consortium consisting of the most prevalent gut bacteria in humans. In addition, we investigated the …

Formulation Development And Evaluation Of Spray-Dried Astaxanthin-Loaded Self-Microemulsifying Delivery Systems In Tablets, Wai Thet Aung

Chulalongkorn University Theses and Dissertations (Chula ETD)

An antioxidant activity of astaxanthin (AST) is one of the desirable bioactive properties for nutraceutical and pharmaceutical products. However, poor aqueous solubility and high possibility of degradation of AST limit its efficacy of oral absorption and bioavailability. Therefore, the aim of this study was to develop and optimize the spray-dried astaxanthin-loaded self-microemulsifying delivery system (SMEDS) in tablets to improve solubility, dissolution, and bioavailability of AST. By using a mixture design, liquid AST SMEDS (L-AST SMEDS) formulations containing rice bran oil, Kolliphor® RH40, and Span® 20 were optimized based on the desirability function. The optimal L-AST SMEDS composed of rice bran …

Muscle Blood Flow Is Independent Of Conduit Artery Diameter Following Prior Vasodilation In Males, Timothy R. Rotarius, Jakob D. Lauver, John R. Thistlethwaite, Barry W. Scheuermann

Kinesiology

At the onset of exercise in humans, muscle blood flow (MBF) increases to a new steady-state that closely matches the metabolic demand of exercise. This increase has been attributed to “contraction-induced vasodilation,” comprised of the skeletal muscle pump and rapid vasodilatory mechanisms. While most research in this area has focused on forearm blood flow (FBF) and vascular conductance, it is possible that separating FBF into diameter and blood velocity can provide more useful information on MBF regulation downstream of the conduit artery. Therefore, we attempted to dissociate the matching of oxygen delivery and oxygen demand by administering glyceryl tri-nitrate (GTN) …

Identification Of Serum Predictors Of N-Acetyl-L-Cysteine And Isoproterenol Induced Remodelling In Cardiac Hypertrophy, Dharaniyambigai Kuberapandian, Victor Arokia Doss

Turkish Journal of Biology

Cardiac hypertrophy (CH), leading to cardiac failure is due to chronic metabolic alterations occurring during cellular stress. Besides the already known relationship between oxidative stress and CH, there are implications of reductive stress leading to CH. This study attempted to develop reductive stress-based CH rat model using n-acetyl-L-cysteine (NAC), a glutathione agonist that was compared with typical isoproterenol (ISO) induced CH model. The main objective was to identify serum metabolites that can serve as potent predictors for seven routine clinical and diagnostic parameters in CH: 3-hydroxybutyrate (3-HB), lactic acid (LA), urea, and ECG-CH parameters (QRS complex, R-amplitude, R-R interval, heart …

Evening And Overnight Cardiovascular And Arterial Stiffness Responses To Simulated Binge Drinking, Grant Thivierge

Dissertations, Master's Theses and Master's Reports

Acute alcohol consumption has been shown to increase blood pressure, while chronic heavy alcohol consumption is associated with the development of hypertension. Another factor that contributes to hypertension is arterial stiffness. While evidence suggests light to moderate alcohol consumption can decrease arterial stiffness, the impact of binge alcohol consumption on acute and overnight changes of arterial stiffness remains unknown. Twenty-seven participants (14 female; 13 male) received a binge alcohol dose or fluid control randomly one month apart. Alcohol or fluid control doses were administered in two equally divided allocates at 8 and 9 pm. A 1:3 mixture of 190 proof …

Short-Term Fasting And Autonomic Control, Joshua Gonzalez

Dissertations, Master's Theses and Master's Reports

Obesity is a chronic metabolic disorder associated with increased risk of cardiovascular disease. Evidence suggests that chronic intermittent fasting improves cardiometabolic health and reduces arterial blood pressure. However, the mechanisms underlying the reductions in blood pressure and improved cardiovascular health observed from chronic fasting studies remain unclear. The autonomic nervous system has a central role in the regulation of blood pressure and is essential for cardiovascular homeostasis. We conducted a study to investigate how acute fasting influences autonomic control of blood pressure at rest and during stress. Twenty-five young, healthy, normal weight, normotensive participants were tested twice, once in the …

Matters Of Biocybersecurity With Consideration To Propaganda Outlets And Biological Agents, Xavier-Lewis Palmer, Ernestine Powell, Lucas Potter, Thaddeus Eze (Ed.), Lee Speakman (Ed.), Cyril Onwubiko (Ed.)

Electrical & Computer Engineering Faculty Publications

The modern era holds vast modalities in human data utilization. Within Biocybersecurity (BCS), categories of biological information, especially medical information transmitted online, can be viewed as pathways to destabilize organizations. Therefore, analysis of how the public, along with medical providers, process such data, and the methods by which false information, particularly propaganda, can be used to upset the flow of verified information to populations of medical professionals, is important for maintenance of public health. Herein, we discuss some interplay of BCS within the scope of propaganda and considerations for navigating the field.

Influence Of Sex On Lower Limb Skeletal Muscle Oxidative Capacity And Muscle Diffusion In Endurance Trained Individuals, Lotte Black

Open Access Master's Theses

Near infra-red spectroscopy (NIRS) is a noninvasive methodology that allows in vivo measurement of the skeletal muscle tissue metabolism. Recently, a novel, of short duration, NIRS-based approach, based on a brief set of muscle contractions followed by a series of repeated intermittent arterial occlusions, has been validated to determine the skeletal muscle oxygen consumption (mV̇ O₂) recovery rate constant (k, min^-1), which is proportional to the muscle oxidative capacity. However, since its relatively recent introduction, the validity of this approach in investigating the difference in lower limb muscle oxidative capacity between female and male …

Bacterial Association Networks From Healthy And Cancer-Associated Gut Microbiomes, Mark Loftus

Electronic Theses and Dissertations, 2020-2023

The human gastrointestinal tract is colonized by a diverse community of symbiotic microorganisms, mainly bacteria, that are known to play essential roles in maintaining the health of their human host. Disruption of this bacterial community has been associated with numerous diseases, including Colorectal Cancer (CRC). CRC is one of the leading causes of cancer-related deaths worldwide. As such, focus has been placed on the modulation of the bacterial community within the cancer-associated gut microbiome as the next step in possible CRC treatment and prevention strategies. To use the bacterial community for these purposes, a better understanding of the associations that …

Identifying The Links Between Mental Frameworks, Context Features, And Driver Attention In Complete Streets Environments, Patricia Tice

Electronic Theses and Dissertations, 2020-2023

Complete street systems integrate a wide range of users in the same space, with unequal risks and responsibilities. This makes driver attention a critical factor in assuring the safety of vulnerable users. The Conditioned Anticipation of People psychological model of driver attention proposes that drivers reflexively reengage their metacognitive processes when they anticipate visually interacting with the human face or form due to the neurological priority that the brain places on human recognition. To test this model, an eye-tracking tabulation was generated from the SHRP2 Naturalistic Driving Study that measured midsegment percent of time on-task and multitasking behavior for 200 …

Effects Of Hiv-1 Gp120 On Intracellular Levels Of Iron And Reactive Oxygen Species: Implications For Lysosomal Stress, Koffi L. Lakpa

Theses and Dissertations

Approximately 1.2 million people in the U.S.A are living with HIV-1. The development of antiretroviral therapeutics has increased the life expectancy of people living with HIV-1 (PLWH). Yet, there is a growing concern for aging HIV-positive individuals because about 50% of PLWH develop neurological impairments, termed HIV-associated neurocognitive disorders (HAND). There are no treatments for HAND and the mechanisms underlying its pathogenesis remain unclear. Several factors are implicated in HAND pathogenesis, such as HIV-1 coat protein gp120, endolysosome and mitochondrial dysfunction, and elevated levels of reactive oxygen species (ROS). Endolysosomes are acidic organelles that contain readily releasable stores of cations, …
