Rationale For, Initiation And Titration Of The Basal Insulin/Glp-1ra Fixed-Ratio Combination Products, Ideglira And Iglarlixi, For The Management Of Type 2 Diabetes, Virginia Valentine, Jennifer Goldman, Jay H. Shubrook

Faculty Publications & Research of the TUC College of Osteopathic Medicine

Type 2 diabetes (T2D) is a progressive disease affecting glucose regulation and a major cause of morbidity and mortality globally. Many patients are not escalated up the treatment ladder appropriately despite failing to achieve glycemic control, with barriers such as fear of hypoglycemia, weight gain, and treatment burden recognized as factors. Exogenous basal insulin is titrated to address control of fasting plasma glucose and may preserve residual β-cell function, thus promoting a greater endogenous prandial insulin response. Native glucagon-like peptide-1 (GLP-1) is a peptide hormone secreted by the gut in response to nutrient ingestion; it increases insulin secretion, inhibits glucagon …

Manuscripts, Articles, Book Chapters and Other Papers

A plasma component is responsible for altered glomerular permeability in patients with focal segmental glomerulosclerosis. Evidence includes recurrence after renal transplantation, remission after plasmapheresis, proteinuria in infants of affected mothers, transfer of proteinuria to experimental animals, and impaired glomerular permeability after exposure to patient plasma. Therapy may include decreasing synthesis of the injurious agent, removing or blocking its interaction with cells, or blocking signaling or enhancing cell defenses to restore the permeability barrier and prevent progression. Agents that may prevent the synthesis of the permeability factor include cytotoxic agents or aggressive chemotherapy. Extracorporeal therapies include plasmapheresis, immunoadsorption with protein A …

Lead Content Of Lip Balms: A Cross Sectional Convenience Sample With Exposure Assessment Estimating An Average Daily Intake For Young Children, Julie Grunklee

Dissertations and Theses @ UNI

Lead remains one of the largest environmental toxins affecting children today (Costa, et al., 2004). It is associated with lower IQ, learning difficulties, decreased economic potential and other negative health effects and social behaviors (Kordas et al., 2006). In the United States (U.S.), high amounts of lead remain in and immediately around housing built before 1978 (Tarragó, 2015) as well as a variety of other sources, including cosmetics such as lip balms, that are marketed to the most lead-vulnerable population: young children. Lip balm was found to be the source a lead poisoned child in Minnesota (Minnesota resident, 28 years …

Cyclic Ac253, A Novel Amylin Receptor Antagonist, Improves Cognitive Deficits In A Mouse Model Of Alzheimer’S Disease, Rania Soudy, Aarti Patel, Wen Fu, Kamaljit Kaur, David Mactavish, David Westaway, Rachel Davey, Jeffrey Zajac, Jack Jhamandas

Pharmacy Faculty Articles and Research

Introduction: Amylin receptor serves as a portal for the expression of deleterious effects of amyloid b-protein (Ab), a key pathologic hallmark of Alzheimer’s disease. Previously, we showed that AC253, an amylin receptor antagonist, is neuroprotective against Ab toxicity in vitro and abrogates Ab-induced impairment of hippocampal long-term potentiation.

Methods: Amyloid precursor protein–overexpressing TgCRND8 mice received intracerebroventricularly AC253 for 5 months. New cyclized peptide cAC253 was synthesized and administered intraperitoneally three times a week for 10 weeks in the same mouse model. Cognitive functions were monitored, and pathologic changes were quantified biochemically and immunohistochemically.

Results: AC253, when administered …

The Autocrine Role Of Proteoglycan-4 (Prg4) In Modulating Osteoarthritic Synoviocyte Proliferation And Expression Of Matrix Degrading Enzymes, Ali Alquraini, Maha Jamal, Ling Zhang, Tannin Schmidt, Gregory D. Jay, Khaled A. Elsaid

Pharmacy Faculty Articles and Research

Background: Lubricin/proteoglycan 4 (PRG4) is a mucinous glycoprotein secreted by synovial fibroblasts and superficial zone chondrocytes. Recently, we showed that recombinant human PRG4 (rhPRG4) is a putative ligand for CD44 receptor. rhPRG4-CD44 interaction inhibits cytokine-induced rheumatoid arthritis synoviocyte proliferation. The objective of this study is to decipher the autocrine function of PRG4 in regulating osteoarthritic synoviocyte proliferation and expression of catabolic and pro-inflammatory mediators under basal and interleukin-1 beta (IL-1β)- stimulated conditions.

Methods: Cytosolic and nuclear levels of nuclear factor kappa B (NFκB) p50 and p65 subunits in Prg4+/+ and Prg4-/- synoviocytes were studied using western blot. Nuclear …

Il-15 Activates The Jak3/Stat3 Signaling Pathway To Mediate Glucose Uptake In Skeletal Muscle Cells, James E. Krolopp, Shantaé M. Thornton, Marcia J. Abbott

Health Sciences and Kinesiology Faculty Articles

Myokines are specialized cytokines that are secreted from skeletal muscle (SKM) in response to metabolic stimuli, such as exercise. Interleukin-15 (IL-15) is a myokine with potential to reduce obesity and increase lean mass through induction of metabolic processes. It has been previously shown that IL-15 acts to increase glucose uptake in SKM cells. However, the downstream signals orchestrating the link between IL-15 signaling and glucose uptake have not been fully explored. Here we employed the mouse SKM C2C12 cell line to examine potential downstream targets of IL-15-induced alterations in glucose uptake. Following differentiation, C2C12 cells were treated overnight with 100 …

Pharmacy Faculty Articles and Research

Dyshormonogenesis due to thyroglobulin (TG) gene mutations is a rare cause of congenital hypothyroidism with an estimated incidence of approximately 1 in 100,000 newborns. The TG gene is organized in 48 exons, spanning over 270 kb on human chromosome 8q24. The human TG mRNA is 8.5 Kb long and the preprotein monomer is composed of a 19 amino acids signal peptide followed by a 2749 residues polypeptide. Until now, one hundred seventeen deleterious mutations in the human TG gene have been identified and characterized, originating structural changes in the protein that alter the normal protein folding, assembly and …

Comparison Of Outcomes Following A Switch From A Brand To An Authorized Vs. Independent Generic Drug, Richard Hansen, Jingjing Qian, Richard L. Berg, James G. Linneman, Enrique Seoane-Vazquez, Sarah Dutcher, Saeid Raofi, C. David Page, Peggy L. Peissig

Pharmacy Faculty Articles and Research

Authorized generics are identical in formulation to brand drugs, manufactured by the brand company but marketed as a generic. Generics, marketed by generic manufacturers, are required to demonstrate pharmaceutical and bioequivalence to the brand drug, but repetition of clinical trials is not required. This retrospective cohort study compared outcomes for generics and authorized generics, which serves as a generic vs. brand proxy that minimizes bias against generics. For the seven drugs studied between 1999-2014, 5,234 unique patients were on brand drug prior to generic entry and 4,900 (93.6%) switched to a generic. During the 12-months following the brand-to-generic switch, patients …

Synthesis Of Rhamnosylated Arginine Glycopeptides And Determination Of The Glycosidic Linkage In Bacterial Elongation Factor P, Siyao Wang, Leo Corcilius, Phillip B. Sharp, Andrei Rajkovic, Michael Ibba, Benjamin L. Parker, Richard J. Payne

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

A new class of N-linked protein glycosylation – arginine rhamnosylation – has recently been discovered as a critical modification for the function of bacterial elongation factor P (EF-P). Herein, we describe the synthesis of suitably protected α- and β-rhamnosylated arginine amino acid “cassettes” that can be directly installed into rhamnosylated peptides. Preparation of a proteolytic fragment of Pseudomonas aeruginosa EF-P bearing both α- and β-rhamnosylated arginine enabled the unequivocal determination of the native glycosidic linkage to be α through 2D NMR and nano-UHPLC-tandem mass spectrometry studies.

Reduced mitochondrial DNA copy number, mitochondrial DNA mutations or disruption of electron transfer chain complexes induce mitochondria-to-nucleus retrograde signaling, which induces global change in nuclear gene expression ultimately contributing to various human pathologies including cancer. Recent studies suggest that these mitochondrial changes cause transcriptional reprogramming of nuclear genes although the mechanism of this cross talk remains unclear. Here, we provide evidence that mitochondria-to-nucleus retrograde signaling regulates chromatin acetylation and alters nuclear gene expression through the heterogeneous ribonucleoprotein A2 (hnRNAP2). These processes are reversed when mitochondrial DNA content is restored to near normal cell levels. We show that the mitochondrial stress-induced …

The Effects Of Tranexamic Acid On Mortality Rate In Trauma Patients Compared To Trauma Patients With No Tranexamic Acid Treatment, Bradley Earl Tolar

Doctoral Projects

Traumatic injury is the leading cause of death for many age groups. Traumatic accidents caused over 130,000 deaths in the United States in 2014. This DNP project studied the effects of Tranexamic acid on mortality rate in trauma patients. After the completion of a needs assessment at a local level II trauma center, a literature review was performed. The literature showed a decrease in mortality rate when patients were administered Tranexamic acid within 3 hours of injury with statistically significant statistics. Also, the data from the literature showed no correlation between vascular occlusive events and Tranexamic acid use in trauma …
