Physiological And Cognitive Factors Related To Human Performance During The Grand Canyon Rim-To-Rim Hike, 2018 Sandia National Laboratories, NM
Physiological And Cognitive Factors Related To Human Performance During The Grand Canyon Rim-To-Rim Hike, Kristin Divis, Clifford Anderson-Bergman, Robert Abbott, Victoria Newton, Glory Emmanuel-Aviña
Journal of Human Performance in Extreme Environments
Exposure to extreme environments is both mentally and physically taxing, leading to suboptimal performance and even life-threatening emergencies. Physiological and cognitive monitoring could provide the earliest indicator of performance decline and inform appropriate therapeutic intervention, yet little research has explored the relationship between these markers in strenuous settings. The Rim-to-Rim Wearables at the Canyon for Health (R2RWATCH) study is a research project at Sandia National Laboratories funded by the Defense Threat Reduction Agency to identify which physiological and cognitive phenomena collected by non-invasive wearable devices are the most related to performance in extreme environments. In a pilot study, data were ...
Validation Of Minimally-Invasive Sample Collection Methods For Measurement Of Telomere Length, 2017 University of Denver
Validation Of Minimally-Invasive Sample Collection Methods For Measurement Of Telomere Length, Stephanie A. Stout, Jue Lin, Natalie Hernandez, Elyssia Poggi Davis, Judith E. Carroll, Laura M. Glynn
Psychology Faculty Articles and Research
Objective: The discovery of telomere length (TL) as a biomarker of cellular aging and correlate of age-related disease has generated a new field of research in the biology of healthy aging. Although the most common method of sample collection for TL is venous blood draw, less-invasive DNA collection methods are becoming more widely used. However, how TL relates across tissues derived from these sample collection methods is poorly understood. The current study is the first to characterize the associations in TL across three sample collection methods: venous whole blood, finger prick dried blood spot and saliva.
Methods: TL was measured ...
Psycho-Physiologic Emergentism; Four Minds In A Body, 2017 Valparaiso University, Department of Psychology, Valparaiso, USA
Psycho-Physiologic Emergentism; Four Minds In A Body, David L. Rowland, Ion G. Motofei
Journal of Mind and Medical Sciences
The mind-body problem represents one of the most debated topics in the neurosciences. From a psychological standpoint, abstract/non-material data are an intrinsic part of the mind, intervening to a large extent in reasoning and decision making processes. Imaging studies also show a strong correlation between higher cognitive functions (such as working memory) and specific cerebral brain regions (a fronto-parietal network of interacting left and right brain areas). In contrast, the physical/material brain would be unable to interact with abstract-immaterial data, such that the psychological processing of abstract data (processes such as thinking, reasoning, and judgment) is attributed to ...
Ubqln1 : A Multi-Domain Protein With Multiple Functions., 2017 University of Louisville
Ubqln1 : A Multi-Domain Protein With Multiple Functions., Zimple Kurlawala
Electronic Theses and Dissertations
There are 5 Ubiquilin proteins (UBQLN1-4, UBQLN-L), which are evolutionarily conserved and structurally similar. UBQLN proteins have 3 functional domains: N-terminal ubiquitin-like domain (UBL), C-terminal ubiquitin-associated domain (UBA) and STI chaperone-like regions in the middle. Alterations in UBQLN1 gene have been detected in a variety of disorders including Alzheimer’s disease, Amyotropic Lateral Sclerosis and lung cancer. UBQLN1 has been largely studied in neurodegenerative disorders in the context of protein quality control. Several studies have hypothesized that the UBA domain of UBQLN1 binds to poly-ubiquitin chains of substrate and shuttles it to the proteasome via its UBL domain for degradation ...
Local Anesthesia Toxicity, 2017 Otterbein University
Local Anesthesia Toxicity, Nicole Mccleery
Master of Science in Nursing (MSN) Student Scholarship
Local anesthesia (LA) provides a way to relieve temporary pain in a small part of the body and has been used for over 100 years (Fencl, 2015). LA also prevents the passage of surgical stimuli into the central nervous system (CNS) making a surgical procedure less painful for the patient (Noble, 2015). According to Noble, “altering the passage of stimuli from smaller diameter neurons in a confined area with lower drug dosages is called LA, such as the injection of LA around a surgical incision” (Noble, 2015, p.325). LA can be used in a variety of settings, such as ...
Autophagy And Protein Turnover Responses To Exercise-Nutrient Interactions In Human Skeletal Muscle, 2017 Australian Catholic University
Autophagy And Protein Turnover Responses To Exercise-Nutrient Interactions In Human Skeletal Muscle, William J. Smiles
Skeletal muscle is a dynamic tissue comprising the largest protein reservoir of the human body with a rate of turnover of ~1-2% per day. Protein turnover is regulated by the coordination of intracellular systems regulating protein synthesis and breakdown that converge in a spatiotemporal manner on lysosomal organelles responsible for integrating a variety of contractile and nutritional stimuli. One such system, autophagy, which literally means to ‘self-eat,’ involves capturing of cellular material for deliver to, and disintegration by, the lysosome. The autophagic ‘cargo’ is subsequently recycled for use in synthetic reactions and thus maintenance of protein balance. As a dynamic ...

Mixed-Mode Oscillations In Pyramidal Neurons Under Antiepileptic Drug Conditions, Babak V-Ghaffari, M. Kouhnavard, Sherif M. Elbasiouny
Neuroscience, Cell Biology, & Physiology Faculty Publications
Subthreshold oscillations in combination with large-amplitude oscillations generate mixedmode oscillations (MMOs), which mediate various spatial and temporal cognition and memory processes and behavioral motor tasks. Although many studies have shown that canard theory is a reliable method to investigate the properties underlying the MMOs phenomena, the relationship between the results obtained by applying canard theory and conductancebased models of neurons and their electrophysiological mechanisms are still not well understood. The goal of this study was to apply canard theory to the conductance-based model of pyramidal neurons in layer V of the Entorhinal Cortex to investigate the properties of MMOs under ...

Loma Linda University Electronic Theses, Dissertations & Projects
The link between intrauterine environmental conditions and adult cardiovascular system is well established. Independent of lifestyle factors such as poor diet and exercise habits, individuals who have been exposed to stressful conditions in utero show an increased risk of health problems such as hypertension, stroke, and type II diabetes. In support of the Fetal Origin of Adult Disease hypothesis, many labs have reported permanent anatomical and physiological changes associated with fetal stress and nutrient deficiency, with a focus on organ systems such as the kidney and heart. One key idea proposed by many of these studies is the glucocorticoid hypothesis ...
Diagnostic Effectiveness Of High-Sensitivity Troponins, 2017 James Madison University
Diagnostic Effectiveness Of High-Sensitivity Troponins, Sean R. Bodin, Jacqueline Ramirez
Physician Assistant Capstones
Background: Acute myocardial infarctions (AMI) are a leading cause of death in the United States. The key to increasing survivability is early recognition to expedite the proper treatment modalities. In conjunction with the clinical presentation and electrocardiograms, the use of cardiac biomarkers is exponentially important in not only recognizing a cardiac event but also determining the extent of injury. Advancement in laboratory technology has led to the development of high-sensitive troponin (hs-troponin) assays which can detect smaller cardiac troponin serum levels compared to conventional troponin assays. This implies that the use of hs-troponin assays is more effective in the early ...
Humor In Medicine: A Literature Review Of Humor’S Potential Therapeutic Value In Health Care, 2017 University of Arkansas
Humor In Medicine: A Literature Review Of Humor’S Potential Therapeutic Value In Health Care, Weston Michael Grant
Psychological Science Undergraduate Honors Theses
Using humor and laughter within the health care field has the potential to be relevant to patients during treatment, to the patient-caregiver relationship, to the subjective well-being of health care providers, and to the environments’ (e.g., work settings) impact on group relationships (e.g., colleagues). A review of the literature examines how the psychological and physiological effects of laughter and humor within the human body impact health and well-being, how humor and laughter improve the patient-practitioner relationship, and if humor and laughter can potentially impact physician burnout. Several possible implications for these findings are discussed, such as professional medical ...

The purpose of my research is to show the correlation between modern vocal practices and the current medical technology available to help us understand the physiology of the voice. I am studying and analyzing the vocal performance and pedagogical practices from the early church to present day. I want to know why these vocal strategies have changed over time. There have been several different schools of thinking in regards to vocal practices. From the Italian style bel canto singing that was widely ...
Motor Axon Synapses On Renshaw Cells Contain Higher Levels Of Aspartate Than Glutamate, 2017 Wright State University
Motor Axon Synapses On Renshaw Cells Contain Higher Levels Of Aspartate Than Glutamate, Dannette Shanon Richards, Ronald W. Griffith, Shannon H. Romer, Francisco J. Alvarez
Francisco J. Alvarez
Motoneuron synapses on spinal cord interneurons known as Renshaw cells activate nicotinic, AMPA and NMDA receptors consistent with co-release of acetylcholine and excitatory amino acids (EAA). However, whether these synapses express vesicular glutamate transporters (VGLUTs) capable of accumulating glutamate into synaptic vesicles is controversial. An alternative possibility is that these synapses release other EAAs, like aspartate, not dependent on VGLUTs. To clarify the exact EAA concentrated at motor axon synapses we performed a quantitative postembedding colloidal gold immunoelectron analysis for aspartate and glutamate on motor axon synapses (identified by immunoreactivity to the vesicular acetylcholine transporter; VAChT) contacting calbindin-immunoreactive (-IR) Renshaw ...
Using Heart Models For Physiology Teaching And Learning, 2017 Illinois Mathematics and Science Academy
Using Heart Models For Physiology Teaching And Learning, Sowmya Anjur
Over the last few decades, there has been a shift in the classroom from a teacher-centered learning environment, with its emphasis on content delivery, to a student-centered environment focused on inquiry learning (http://www.nsta.org/docs/ PositionStatement_Scienti cInquiry.pdf). With the Next Generation Science Standards (NGSS, 2012) being adopted by many states, students are no longer passive listeners, but actively participate in and initiate class discussions (Weimar, 2013). Additionally, recent technological advances have allowed students to acquire information from sources such as the internet which no longer necessitates the teacher giving lectures (Silver- thorn, 2006). The more student-centered learning ...
Analysis Of Proprioceptive Sensory Innervation Of The Mouse Soleus: A Whole-Mount Muscle Approach, 2017 Wright State University
Analysis Of Proprioceptive Sensory Innervation Of The Mouse Soleus: A Whole-Mount Muscle Approach, Martha Jean Sonner, Marie C. Walters, David R. Ladle
Neuroscience, Cell Biology & Physiology Faculty Publications
Muscle proprioceptive afferents provide feedback critical for successful execution of motor tasks via specialized mechanoreceptors housed within skeletal muscles: muscle spindles, supplied by group Ia and group II afferents, and Golgi tendon organs, supplied by group Ib afferents. The morphology of these proprioceptors and their associated afferents has been studied extensively in the cat soleus, and to a lesser degree, in the rat; however, quantitative analyses of proprioceptive innervation in the mouse soleus are comparatively limited. The present study employed genetically-encoded fluorescent reporting systems to label and analyze muscle spindles, Golgi tendon organs, and the proprioceptive sensory neuron subpopulations supplying ...

The Effects Of Exercise Preconditioning On Focal Ischemic Stroke, 2017 University of Kentucky
The Effects Of Exercise Preconditioning On Focal Ischemic Stroke, Gillian Grohs
Theses and Dissertations--Medical Sciences
Cleaved fragments of the extracellular matrix protein perlecan have been shown to promote neuroprotection and repair after ischemic stroke. The cysteine proteases cathepsin B and L as well as the metalloprotease bone morphogenic protein 1 (BMP-1) are capable of releasing the biologically active C-terminal laminin-like globular domain (LG3) of perlecan. Exercise, a known method of reducing stroke risk and severity, has been shown to increase the expression of some proteases associated with perlecan processing. Using a transient distal middle cerebral artery occlusion (MCAo) model for focal ischemic stroke we show that while 7 days of running only slightly decreased infarct ...
Biomarkers Of Sepsis: A Retrospective Approach, 2017 The University of Akron
Biomarkers Of Sepsis: A Retrospective Approach, Jose M. Roberts
Honors Research Projects
Background: Biomarkers are taking the spotlight in becoming the norm for early diagnoses. Sepsis is an inflammatory disease that increases metabolic rate in children. The first biomarker is hyponatremia. Hyponatremia is a frequent electrolyte imbalance in clinical practice, often observed in children with inflammatory disease and infection. Presence of hyponatremia is associated with electrical signaling imbalances, inflammation and renal dysfunction. The clinical value of hyponatremia in pediatric patients is unknown. The C-reactive protein is a second biomarker. Its presence signifies that necrotic cells and inflammation are present.
Objectives: To evaluate the use of biomarkers in children seen in the Emergency ...
Neuroinflammation In Alzheimer's Disease And Vascular Cognitive Impairment, 2017 University of Kentucky
Neuroinflammation In Alzheimer's Disease And Vascular Cognitive Impairment, Erica M. Weekman
Theses and Dissertations--Physiology
It was once believed that the brain was immunologically privileged with no resident or infiltrating immune cells; however, now it is understood that the cells of the brain are capable of a wide range of inflammatory processes and phenotypes. Inflammation in the brain has been implicated in several disease processes such as Alzheimer’s disease (AD) and vascular cognitive impairment and dementia (VCID); however, the role of inflammation in these two dementias is poorly understood.
When we stimulated a pro-inflammatory phenotype with an adeno-associated viral vector in a transgenic mouse model of AD that develops Aβ plaques, we saw a ...
Effects Of Neonatal Supplemental Oxygen And High Fat Diet On Weight Gain, Ventricular Hypertrophy And Contractility, Shreya Chandrasekar, Melissa L. Bates, Shilpa Vellookunnel, Michael J. Hoover, Madison E. Sturgeon, Austin Murphy
University of Iowa Honors Theses
Premature birth represents about 13% of live births each year. Since lungs of these infants are underdeveloped, they receive supplemental oxygen right after birth, but little is known about its effects on the development of normal physiological responses and whether it impacts long-term cardio-metabolic function. Based on previous studies from our lab that showed increased pulse wave velocity in 12 month old rats exposed to neonatal supplemental oxygen, we hypothesized that neonatal exposure to supplemental oxygen causes cardiac hypertrophy and decreased left ventricular contractility. We also hypothesized that these effects to supplemental oxygen would be enhanced by 10 weeks on ...
Dynamics Of Mitotic Microtubules In Fission Yeast, 2017 University of Colorado, Boulder
Dynamics Of Mitotic Microtubules In Fission Yeast, Patrick Flynn
Undergraduate Honors Theses
Microtubules (MTs) are cytoskeletal polymers that assemble into a biomechanical complex known as the mitotic spindle. The spindle is responsible for the equal partitioning of chromosomes during cell division; an event known as mitosis. The dependence of proper chromosome segregation on the dynamics of individual microtubules (MTs) is not well understood or easy to study due to their small size and quick dynamics. Mathematical models and simulations have been constructed in order to better understand the physical basis of how the mitotic spindle accurately, or inaccurately, divides duplicated chromosomes during mitosis. These models rely on the dynamics parameters of individual ...
