The Science Of Sound: Studying The Cognitive, Emotional, And Physiological Effects Of Frequency, Genre, And Music, Jett Yarborough

Senior Honors Theses

Music influences emotion, physiology, and cognition, yet little is known about how the frequency it is tuned to affects these influences. Prior research has shown that music tuned to 432 Hz can reduce stress, lower blood pressure, and improve sleep. My colleagues and I conducted two studies to investigate this. Our research found that music tuned to 432 Hz promotes a significant increase in memory retention and induces a state of focus and relaxation. These results suggest that shifting from the standard tuning frequency of 440 Hz to 432 Hz could have a profoundly positive impact on our daily lives. …

Sodium And Potassium In Health And Cellular Function, Jordyn Branz

Honors Program: Senior Projects (Public)

Sodium (Na⁺) and potassium (K⁺) are essential electrolytes that regulate numerous physiological processes. These include cell function, nerve transmission, and muscle contraction. The Na+/K+-ATPase plays a critical role in maintaining the balance of these ions by actively transporting three sodium ions out of the cell and two potassium ions into the cell against their concentration gradients. This process is vital for maintaining the resting membrane potential and supporting the function of excitable cells. The Na+/K+-ATPase consists of two main subunits, with the alpha-subunit being primarily responsible for ion transport activity. Isoforms alpha1, alpha2, and alpha3 are tissue-specific and contribute to …

Evaluating The Market Withdrawal Of Andexanet Alfa, Jordyn Linfield, Addisyn Cooper, Alexander Defranco, Emma Gerding, Jessica Kelley, Tyler Henney, Connor Dains, Brenna Hissong, Brittany Bates

Pharmacy and Wellness Review

The coagulation cascade comprises intrinsic, extrinsic, and common pathways that converge when thrombin converts fibrinogen (factor I) into fibrin, leading to fibrin mesh formation, stabilization of the platelet plug, and ultimately thrombus formation. Inhibition of the coagulation cascade can be achieved with a variety of anticoagulant medications, including direct oral anticoagulants (DOACs). The mechanism of action of DOACs is to inhibit either factor Xa or thrombin. Reversal of anticoagulation remains an important clinical consideration when managing patients on DOACs who experience serious bleeding events. Andexanet alfa is a recombinant, modified human factor Xa protein previously indicated for patients receiving rivaroxaban …

Vitamin D Deficiency: "At Risk" Patient Populations And Potential Drug Interactions, Dana Lycans Md, Elias Salloum Md, Matthew K. Wingate Md, Thomas Melvin Md, Grant S. Buchanan Md, Franklin D. Shuler Md, Phd

Marshall Journal of Medicine

Vitamin D is known to play an essential role in calcium homeostasis; however, excessive amounts can have harmful effects. Calcium and vitamin D levels are known to be influenced by drug interactions and pathology ranging from of cancer to cardiovascular disease. Vitamin D supplementation has become widespread, and it is important for clinicians to understand the way that certain conditions and medications interact with vitamin D and calcium homeostasis. The purpose of this review is to outline the benefits and adverse effects of vitamin D and how its levels are affected by certain pathologic and pharmacologic interactions.

Gut Microbiome And Nutrition Interplay In Regulating And Improving Autism Spectrum Disorder Related Social Symptoms, Irenonsen Juliet Eigbe, Christian Moya Gamboa, Jana Gjini, Jaydeep Mukherjee, Susrut Dube

Rowan-Virtua Research Day

The composition of the gut microbiome has been shown to play a role in the onset of neurological disorders, including Autism Spectrum Disorder(ASD). A small variety of recent research articles identify a possible link between onset and severity of ASD related behaviors and the composition of the gut microbiome. The purpose of this review is to identify gaps in the current understanding of the role that nutrition plays in changing the gut microbiome and subsequently altering the onset and severity of behavioral phenotypes in children with ASD. Inclusion criteria comprises peer-reviewed publications relating to children with autism. Exclusion criteria consists …

Influence Of Core Temperature On Psychomotor Performance During Cold Weather Military Training, Douglas Jones, Rebecca Weller, Stephen Eggan, Nicholas Roberts, Weimin Zheng, Jay Heaney, Timothy Dunn

Journal of Human Performance in Extreme Environments

Purpose: Cold environments may deteriorate psychomotor performance due to slowing of neuronal signals, distractions caused by pain and discomfort, and a loss of manual dexterity. The extent to which core temperature (T_c) influences psychomotor performance in the cold has not been established. Therefore, psychomotor performance and T_c were assessed during a cold weather military training exercise to evaluate this relationship.

Methods: Thirty-six military personnel (age: 26 ± 4 yr, ht: 175 ± 8 cm, wt: 79.1 ± 11.1 kg) participating in cold weather training volunteered for this study. Participants completed a 10-min immersion in cold (1°C) water, …

Effects Of A 12-Week Tai Chi And Qigong Training Program On Neuromuscular Function And Postural Stability In Elderly Men With Sarcopenia, Muthanna Harith Ekrayyem, Ali Fawzi Ahmed, Saif Rasheed Ghanim

Baltic Journal of Health and Physical Activity

Background: Sarcopenia is associated with progressive declines in neuromuscular function, balance, and increased systemic inflammation in older adults. This study investigated the effects of a 12-week Tai Chi and Qigong training program in elderly Iraqi men with sarcopenia. Materials and Methods: Thirty men aged 60–65 years with sarcopenia were randomly assigned to an intervention group (n = 15) or a control group (n = 15). Neuromuscular performance, postural stability, gait speed, electromyographic amplitude, IGF-1, and CRP-hs were assessed before and after the intervention. Results: The intervention group showed significant improvements in reaction time, electromyographic amplitude, postural stability, gait …

Prenatal Undernutrition, Metyrapone, And The Cerebrovasculature, Lara Durrant

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, …

The Role Of Gut Dysbiosis In The Loss Of Intestinal Immune Cell Functions And Viral Pathogenesis, Farzaneh Fakharian, Siva Thirugnanam, David A. Welsh, Woong Ki Kim, Jay Rappaport, Kyle Bittinger, Namita Rout

School of Medicine Faculty Publications

The gut microbiome plays a critical role in maintaining overall health and immune function. However, dysbiosis, an imbalance in microbiome composition, can have profound effects on various aspects of human health, including susceptibility to viral infections. Despite numerous studies investigating the influence of viral infections on gut microbiome, the impact of gut dysbiosis on viral infection and pathogenesis remains relatively understudied. The clinical variability observed in SARS-CoV-2 and seasonal influenza infections, and the presence of natural HIV suppressors, suggests that host-intrinsic factors, including the gut microbiome, may contribute to viral pathogenesis. The gut microbiome has been shown to influence the …

Addressing The Lack Of Patient Adherence To Exercise Within The Physical Therapy Clinic And Creating Infographics To Improve Patient Adherence, Gretchen Panovich

Honors Program: Senior Projects (Public)

The primary objective of this applied knowledge project is to develop educational materials to enhance patient adherence. The World Health Organization defines adherence as “the extent to which a person’s behavior…corresponds with agreed recommendations from a healthcare provider.” Within the physical therapy field, non-adherence to exercise is a significant problem linked with increased duration of treatment, more patient complaints, reduced positive clinical outcomes, and even surgical intervention.

Multiple factors affect patient adherence, making it hard to pinpoint a singular cause. Clinical observations and research suggest that belief in the rehabilitation process may suffer due to a prolonged recovery period, lack …
