Evaluation of Hyponatremia Management Pathway Implementation in a Large Academic Health System

Submission Number: 1894079

Patients with severe hyponatremia managed using the Care Signature pathway were more likely to receive hypertonic saline and had lower mortality rates compared to those not managed with the pathway. These results suggest that the pathway can improve clinical outcomes and reduce resource use. Further studies are needed to evaluate its impact on other patients’ outcomes and long-term effectiveness.

The Mitochondria As An Emerging Target Of Self- Renewal In T-Cell Acute Lymphoblastic Leukemia, Majd Al-Hamaly, Evelyn Winter, Jessica S. Blackburn

Markey Cancer Center Faculty Publications

Acute lymphocytic leukemia (ALL) is the most common leukemia in children, with the T-cell subtype (T- ALL) accounting for 15% of those cases. Despite advancements in the treatment of T-ALL, patients still face a dismal prognosis following their first relapse. Relapse can be attributed to the inability of chemotherapy agents to eradicate leukemia stem cells (LSC), which possess self-renewal capabilities and are responsible for the long-term maintenance of the disease. Mitochondria have been recognized as a therapeutic vulnerability for cancer stem cells, including LSCs. Mitocans have shown promise in T-ALL both in vitro and in vivo, with some currently in …

Class Iii Phosphatidylinositol-3 Kinase/Vacuolar Protein Sorting 34 In Cardiovascular Health And Disease, Yuanjun Shen, Jason Gleghorn

Pharmacy Faculty Scholarship

Phosphatidylinositol-3 kinases (PI3Ks) play a critical role in maintaining cardiovascular health and the development of cardiovascular diseases (CVDs). Specifically, vacuolar Protein Sorting 34 (VPS34) or PIK3C3, the only member of Class III PI3K, plays an important role in CVD progression. The main function of VPS34 is inducing the production of phosphatidylinositol 3-phosphate, which, together with other essential structural and regulatory proteins in forming VPS34 complexes, further regulates the mammalian target of rapamycin activation, autophagy, and endocytosis. VPS34 is found to have crucial functions in the cardiovascular system, including dictating the proliferation and survival of vascular smooth muscle cells and cardiomyocytes …

Investigating The Potential Of Broccoli Seed Extract To Attenuate Morphine Tolerance, Atharv Ashwin Battu, Minho Kang, Hamid Akbarali

Pharmacology and Toxicology Publications

Opioids remain one of the most effective treatment strategies for managing severe and persistent pain. However, its long-term use leads to pharmacological tolerance, requiring progressively higher doses to achieve analgesia. This dose escalation increases the risk of life-threatening side effects and dependence, underscoring the urgent need for safe adjuncts to preserve opioid efficacy. Emerging evidence suggests that morphine tolerance is linked to intestinal inflammation and disruption of gut barrier integrity. Broccoli Seed Extract (BSE), rich in the bioactive compound sulforaphane, exhibits antioxidant and anti-inflammatory properties that may protect against these effects. We hypothesized that BSE could prevent the development of …

Alpha-2 Agonist And Fentanyl Reinforcement Interactions In Male And Female Sprague Dawley Rats, Angeline Lopez, Allison Ortiz, Matthew L. Banks

IRBEH/Spit for Science Publications and Presentations

In the two studies that I participated in, a behavioral economic demand curve and choice procedure, we assessed whether two alpha-2 adrenergic agonists (i.e., xylazine, clonidine, and lofexidine) altered fentanyl reinforcement in male and female sprague dawley rats. We hypothesized that xylazine and clonidine would enhance fentanyl reinforcement in a proportion-dependent manner. Lofexidine interactions with fentanyl were more difficult to predict. The data showed that xylazine did not enhance fentanyl reinforcement. Furthermore, these results were consistent with those of clonidine and lofexidine. In opposition to xylazine, clonidine and lofexidine are approved for human use for antinociception, reduction of blood pressure, …

The alarmingly high prevalence of obesity in older adults coupled with the negative health effects of chronic inflammation in both obesity and aging highlight the importance of studies investigating the impacts of obesity on age-related inflammation. Since shifts in peripheral T-cell metabolism and function drive systemic inflammation in both obesity and aging, we hypothesize that obesity impacts the Th17-dominated inflammaging profile we identified in lean subjects and thus modifies the anti-inflammatory effects of geroprotective drugs like metformin. New cytokine profiling data showed that CD4+ T cells from older people with obesity generate a profile that specifically excludes Th17 cytokines. Metformin …

Bilirubin Hepatic And Intestinal Transport And Catabolism: Physiology, Pathophysiology, And Benefits, Zachary A. Kipp, Sally N. Pauss, Genesee J. Martinez, Terry D. Hinds, Jr., Wang-Hsin Lee

Pharmacology and Nutritional Sciences Faculty Publications

Bilirubin, a metabolite derived from heme degradation, has traditionally been regarded as a waste product and a marker of liver injury. However, increasing evidence suggests that bilirubin also functions as a hormone, and reduced levels are associated with metabolic dysfunction. Studies have shown a strong association between low circulating bilirubin levels and an increased risk of metabolic disorders and cardiovascular disease. To advance bilirubin-based treatment strategies, it is essential to elucidate the mechanisms underlying bilirubin transport and metabolism. Therefore, we provide an in-depth discussion of bilirubin production and its subsequent fates, with a particular focus on the transport between the …

Cd47: An Immunoregulatory Nexus In Liver And Gastrointestinal Disorders, Josephine Otuagomah, Alana Newcomb, Taesik Gwag, Shuxia Wang

Pharmacology and Nutritional Sciences Faculty Publications

Cluster of differentiation 47 (CD47) is a widely expressed transmembrane protein that serves as a critical immunoregulatory checkpoint in both homeostatic and pathological conditions of the digestive system. It interacts with signal regulatory protein alpha to send a ‘do not eat me’ signal, thereby preventing phagocytosis and shaping immune responses. Beyond immunity, CD47 also influences cell death, growth and metabolism through interactions with integrins and thrombospondin-1. Recent studies implicate CD47 as a central nexus in the pathogenesis of diverse liver and gastrointestinal disorders, including metabolic dysfunction-associated steatotic liver disease, metabolic dysfunction-associated steatohepatitis, inflammatory bowel disease, liver ischaemia-reperfusion injury, drug-induced liver …

Brain signaling of calcineurin (CN) and nuclear factor of activated T-cells (NFAT) transcription factor increases in Alzheimer disease (AD) and is associated with synaptic loss, neurodegeneration, neuroinflammation, amyloid-β (Aβ) production, and cognitive decline. CN/NFAT inhibitors ameliorate these neuropathologies in mouse models of AD. Further, chronic use of tacrolimus in transplant patients reduces risk of AD. Beagles naturally develop Aβ plaques and cognitive dysfunction. We evaluated the impact of FDA-approved CN inhibitor, tacrolimus, and experimental NFAT inhibitor, Q134R, on cognitive outcomes during a three-year prevention study in 37 middle-aged beagles. While beagles treated with CN/NFAT inhibitors showed differences in the pattern …

Targeting Prmt5 In Inflammation And Cancer: A Nexus Of Endotoxin Signaling, Antigen Presentation And Immune Evasion., Jimmy James Msemo

Theses and Dissertations--Medical Sciences

Protein Arginine Methyltransferase 5 (PRMT5) is a member of PRMT family that controls both intrinsic and extrinsic oncogenic processes [1]. Protein arginine methyltransferase 5 (PRMT5) is a type II methyltransferase that exerts widespread influence over gene expression, splicing, DNA repair, and immune regulation through symmetric dimethylation of arginine residues on histone and non-histone proteins [2]. The addition of methyl groups induces gene silencing through producing dictatorial histone marks like H2AR3ne2s, H3R8me2s and H4R3mes [3], which act as epigenetic repressive marks on gene promoters. In non-histone proteins, PRMT5 can methylate and regulate transcription factor proteins such as p53, E2F1, and p65, …

Impact Of Tetrahydrocannabinol (Thc) On Daphnia Magna Heart Rate, Ashley Cosgrave

Williams Honors College, Honors Research Projects

Marijuana (Cannabis) is currently federally illegal within the United States and classified as a Schedule I drug. This leaves a large research gap on the impacts of Tetrahydrocannabinol (THC) use. Daphnia magna are frequently used as a model organism for the human heart and toxicology screenings due to their myogenic heart, similarities in physiological pathways, and sensitivity to toxins. As such, in order to bridge the research gap and uncover potential use of Daphnia magna as a model organism for humans in regard to impact on heart rate, we hypothesized that if Daphnia magna possess CB1 receptors or an equivalent …

High-Throughput Drug Screening For Disease-Modifying Arthritis Therapy, Janapriya Vijayakumar

Honors Undergraduate Theses

Current therapy for arthritis predominantly focuses on the symptoms rather than the underlying causes of disease progression. Thus, it is necessary to identify novel drugs which target the underlying molecular basis of such diseases. Using high-throughput cell-based drug screening, we screened 458 different compounds, narrowed down from 811 starting compounds from the NIH Mechanistic Set. We selected drugs from the Mechanistic Set following Lipinski's Rule of 5 to ensure optimal pharmacokinetic properties. The study used modified primary human chondrocytes (IIAM-PRG4Luc), which secrete a lubricin promoter-driven luciferase reporter. We use this luciferase expression as a proxy to measure lubricin, a compound …
