A Study Of The Analysis Of Hemp-Derived Oil Products: Development Of A Method For The Analysis Of Phytocannabinoids In Medicinal Products, Erin Johnson

Theses and Dissertations--Pharmacology and Nutritional Sciences

Human interactions with cannabis have a history spanning millennia as a source of fiber, food, and medicine. The plant came across Asia, Europe, and Africa with the movements of people and travelers eventually coming to the Americas with European explorers. In colonizing North America, cannabis fiber was key to the production of canvas and ropes for ships. Although fiber was the driver for cannabis production in the United States, medicinal uses were prevalent and propelled the eventual regulations. The Pure Food and Drug Act of 1906 mandated accurate labeling on drugs such as cannabis followed by the Marihuana Tax Act …

Multimodal Medicine: Pain Control Potential, Tyler Ostlund

Master of Science in Nursing Family Nurse Practitioner

Due to the continual problem with overuse of, overdose on, and abuse of opioid medications for the past three decades it is paramount that effective, cheap, and above all safe forms of pain control are studied and applied. Multimodal pain management utilizes a combination of pharmacological and non pharmacological therapies in synergy to control pain and reduce dependence on strictly opioids. Combining the effects of medications or therapies that focus on treating different types or sources of pain such as inflammatory pain, neurological pain, etc. With the adoption of this method of pain management, the longstanding effects of the opioid …

Modified Ysk12-Mend-Sirna In Dendritic Cells For Cancer Immunotherapy, Syed S. Alam

UROP Posters

Tumors may induce tolerogenesis through signaling dendritic cells to produce tolerogenic molecules, such as indoleamine 2, 3-dioxygenase 1 (IDO1). Tumor-associated immunosuppression is associated with higher mortality in patients. Small interfering RNA (siRNA) has been shown to silence specific target genes in the target cell. The siRNA associated with these genes could support a gene knockdown of these immunosuppressors and reduce mortality. Delivery of these therapeutic nucleic acids is difficult in vivo because siRNA is easily broken down inside the cell and the bloodstream through present nucleases. Use of liposome polymers has been reviewed extensively in literature. YSK12-C4, a lipid nanoparticle …

Steroid-Refractory Lichenoid Eruption Associated With Pembrolizumab In A Patient With Non-Small Cell Lung Cancer, Leon Kou, Sanjay Agarwal, Alyssa Miceli, Logan Kolb, Karthik Krishnamurthy, Shawn Schmieder

HCA Healthcare Journal of Medicine

Programmed cell death receptor 1 (PD-1) inhibitors are promising and effective treatments for various cancers. Cutaneous adverse events, such as lichenoid drug eruptions, are well-known common side effects associated with PD-1 inhibitors. Lichenoid drug eruptions associated with PD-1 inhibitors show rapid improvement with high potency topical steroids and do not require cessation of the offending drug. We present the case of an 84-year-old female with progressive pembrolizumab therapy-associated lichenoid eruption that was resistant to several treatments and ultimately required discontinuation of pembrolizumab and treatment with methotrexate to resolve. This report includes histological findings of the pembrolizumab-associated lichenoid eruption.

Adipose-Specific Pparα Knockout Mice Have Increased Lipogenesis By Pask–Srebp1 Signaling And A Polarity Shift To Inflammatory Macrophages In White Adipose Tissue, Terry D. Hinds, Jr., Zachary A. Kipp, Mei Xu, Frederique B. Yiannikouris, Andrew J. Morris, Donald F. Stec, Walter Wahli, David E. Stec

Pharmacology and Nutritional Sciences Faculty Publications

The nuclear receptor PPARα is associated with reducing adiposity, especially in the liver, where it transactivates genes for β-oxidation. Contrarily, the function of PPARα in extrahepatic tissues is less known. Therefore, we established the first adipose-specific PPARα knockout (Ppara^FatKO) mice to determine the signaling position of PPARα in adipose tissue expansion that occurs during the development of obesity. To assess the function of PPARα in adiposity, female and male mice were placed on a high-fat diet (HFD) or normal chow for 30 weeks. Only the male Ppara^FatKO animals had significantly more adiposity in the inguinal white …

Modulating The Tumor Microenvironment To Improve Immunotherapy Treatments, Lleayem Nazario-Johnson, David Rowley

Senior Honors Projects

Advances in immunotherapy are revolutionizing the treatments of certain cancers, especially those in the blood. However, wider applications for eradicating solid tumors have been slow to emerge. A likely reason is the presence of myeloid-derived suppressor cells (MDSCs) in the tumor microenvironment that secrete immunosuppressive molecules which attenuate the attack of immune cells. We hypothesize that small molecule Wnt/Beta- Catenin inhibitors can be used to modulate the immunosuppressive actions of MDSCs and increase the effectiveness of immunotherapy treatments, such as with chimeric antigen receptor (CAR) T-cells. The Wnt/Beta-Catenin Pathway has been shown to be a crucial driving force behind the …

Preclinical Development Of Epicertin, A Novel Biotherapeutic For The Treatment Of Ulcerative Colitis., Micaela Ann Reeves

Electronic Theses and Dissertations

Epicertin (EPT) is a recombinant variant of the cholera toxin B subunit with a C-terminal KDEL endoplasmic retention motif. Previously, orally administered EPT demonstrated mucosal healing activity in acute and chronic dextran sulfate sodium colitis models, indicating its therapeutic potential for ulcerative colitis (UC) treatment. However, oral dosing with EPT requires neutralization of gastric acid prior to administration, hindering its facile application in the treatment of chronic diseases like UC. One solution to this issue is that EPT may also be administered intracolonically without losing efficacy. This work describes the determination of a target intracolonic dose of EPT for future …

Assessing The Role Of Arsenic Exposure And Mirna-186 In Skin Tumorigenesis And Chromosomal Instability., Angeliki Lykoudi

Electronic Theses and Dissertations

Chronic arsenic exposure through drinking water is a global health issue, affecting more than 200 million people. Arsenic is a group I human carcinogen and causes chromosomal instability (CIN). Arsenic exposure is the second most cause of skin cancer after UV radiation. MiR-186 is overexpressed in arsenic-induced squamous cell carcinoma relative to premalignant hyperkeratosis. Predicted targets of miR-186 are cell cycle regulators. Thus, we hypothesize that miR-186 overexpression drives malignant transformation of HaCaT cells by induction of CIN. Stable clones of HaCaT transfected with pEP-miR-186 expression vector or empty vector were maintained under puromycin selection were exposed to 0 or …

Lysergic Acid Diethylamide Induces Increased Signalling Entropy In Rats’ Prefrontal Cortex, Aurora Savino, Charles D. Nichols

School of Medicine Faculty Publications

Psychedelic drugs are gaining attention from the scientific community as potential new compounds for the treatment of psychiatric diseases such as mood and substance use disorders. The 5-HT2A receptor has been identified as the main molecular target, and early studies pointed to an effect on the expression of neuroplasticity genes. Analysing RNA-seq data from the prefrontal cortex of rats chronically treated with lysergic acid diethylamide (LSD), we describe the psychedelic-induced rewiring of gene co-expression networks, which become less centralised but more complex, with an overall increase in signalling entropy typical of highly plastic systems. Intriguingly, signalling entropy mirrors, at the …

Pharmacology and Nutritional Sciences Faculty Publications

Population-based studies identified an association between a prior pregnancy complicated by gestational diabetes mellitus (GDM) and cardiac hypertrophy and dysfunction later in life. It is however unclear whether GDM initiates this phenotype and what are the underlying mechanisms. We addressed these questions by using female rats that express human amylin (HIP rats) as a GDM model and their wild-type (WT) littermates as the normal pregnancy model. Pregnant and two months postpartum HIP females had increased left-ventricular mass and wall thickness compared to non-pregnant HIP females, which indicates the presence of concentric hypertrophy. These parameters were unchanged in WT females during …

Mental Health Or Cardiac Health. Is There A Reason To Choose? Cardiac Arrhythmias Induced By Atomoxetine And Methylphenidate, Gabriel Cismaru, Viorel Lupu

Journal of Mind and Medical Sciences

The current treatment of Attention Deficit Disorder and Attention Deficit with Hyperactivity consists mainly in the administration of Straterra (Atomoxetine) Concerta and Ritalin (Methylphenidate). The FDA warned that the products might increase systolic, diastolic blood pressure, and lead to ventricular arrhythmias. Arrhythmic events and sudden cardiac death were described in adults with preexistent heart disease. However, studies on children have failed to demonstrate a clear association between the arrhythmic events and these drugs, as demonstrated in adults. What should the attitude of the pediatric psychiatrist be towards the administration of these products? What examination should be made by the psychiatrist …

Serotonin 5-Ht2a Receptor Activity Mediates Adipocyte Differentiation Through Control Of Adipogenic Gene Expression, Bangning Yu, Diana M. Battaglia, Timothy P. Foster, Charles D. Nichols

School of Medicine Faculty Publications

Serotonin 5-HT2 receptors are expressed in many tissues and play important roles in biological processes. Although the 5-HT2A receptor is primarily known for its role in central nervous system, it is also expressed in peripheral tissues. We have found that 5-HT2A receptor antagonists inhibit human subcutaneous primary adipocyte differentiation. We also show that siRNA knockdown of the 5-HT2A receptor blocks differentiation. Using gene expression analysis in combination with receptor antagonists we found that activity of 5-HT2A receptors is necessary very early in the differentiation process to mediate expression of adipogenic genes, including peroxisome proliferator-activated receptor gamma (ppar-γ), adipocyte protein 2 …
