The Reliability Of Histamine Pharmacodynamic Response Phenotype Classification In Children With Allergic Disease., Shaun S Kumar, Xiaoxi Liu, Catherine M Sherwin, Bridgette Jones

Manuscripts, Articles, Book Chapters and Other Papers

We have identified distinct histamine pharmacodynamic response phenotypes in children with allergic disease utilizing histamine iontophoresis with laser Doppler (HILD). These response phenotypes may be relevant in guiding therapeutic decision making for agents targeting the allergic response pathways. However, the reliability of these response phenotypes has not been assessed. Therefore, we performed HILD in children with allergic rhinitis and/or asthma on two to three separate occasions. HILD response-time data were analyzed in NONMEM using a linked effect PKPD model. Examination of observed vs. classified response phenotypes predicted response plots and the sum of residuals. The intraclass correlation coefficient (ICC) was …

The Effects Of Trichloroethylene On The Germination And Early Development Of Radish, Butternut Squash, Corn, And Soybean, Sarah Jaksich

UNO Student Research and Creative Activity Fair

Trichloroethylene (TCE) is a small molecule used as a metal degreaser and as an extraction solvent for lipids. Historically, TCE has been used to clean missiles and rockets after testing at military sites. However, TCE has decreased in use due to its potential health hazards. TCE is particularly dangerous because it is soluble in water and easily seeps into ground water. As a result, TCE has contaminated groundwater in Mead, Nebraska. The town is near the formal Nebraska Ordnance Plant, a military factory specializing in bomb assembly, ammonium nitrate production, and explosives burning. Soil sampling in Mead indicated TCE levels …

The Diffusion Of Artificial Intelligence/Machine Learning Methods And Data Analytics Into An Undergraduate Nursing Research Course, Mary Anne Schultz

Q2S Enhancing Pedagogy

The project is the adoption of principles of Artificial Intelligence (AI)/Machine Learning and Data Analytics into a traditional nursing research (hypothesis testing) course. Necessitated by the recent entrance of “Big Data” use in health care, there is an urgent need to inject an understanding of the AI/ML techniques necessary to extract, organize and derive meaning from this huge amount of evidence in clinical decision-making.

Catalytic, Selective, And Stereocontrolled Construction Of C4 Quaternary And Homobenzylic Dihydroisoquinolones By Sp3 C–H Benzylation, Timothy K. Beng, Antonio Moreno

All Faculty Scholarship for the College of the Sciences

C1 benzylated isoquinoline derivatives constitute the core of benzylisoquinoline alkaloids (BIAs). However, their C4 congeners remain elusive. Here, we describe a diastereoselective, catalytic, and modular C(sp³)–C(sp³) coupling protocol wherein β-amino sp³ C–H bonds of readily affordable vicinally functionalized dihydroisoquinolones are replaced by sp³ C–benzyl bonds. The method provides expedient access to C4 quaternary and homobenzylic dihydroisoquinolones, which are attractive fragments for potential drug discovery.

Protection Against Acute Cerebral Ischemia/Reperfusion Injury By Qishenyiqi Via Neuroinflammatory Network Mobilization, Yule Wang, Guangxu Xiao, Xhuang He, Xinyan Liu, Lin Zhu, Xinyue Yang, Yiqian Zhang, John Orgah, Benjamin Feng, Xiaoying Wang, Boli Zhang, Yan Zhu

Peer Reviewed Articles

Cerebral ischemia/reperfusion injury (CI/RI) is a common feature of ischemic stroke, involving a period of impaired blood supply to the brain, followed by the restoration of cerebral perfusion through medical intervention. Although ischemia and reperfusion brain damage is a complex pathological process with an unclear physiological mechanism, more attention is currently focused on the neuroinflammatory response of an ischemia/reperfusion origin, and anti-inflammatory appears to be a potential therapeutic strategy following ischemic stroke. QiShenYiQi (QSYQ), a component-based Chinese medicine with Qi-tonifying and blood-activating property, has pharmacological actions of anti-inflammatory, antioxidant, mitochondrial protectant, anti-apoptosis, and antiplatelet aggregation. We have previously reported that …

Activation Of The Sonic Hedgehog Effector Smoothened Counteracts L-Dopa Induced Dyskinesia By Restoring Cholinergic Interneuron Function, Lauren Malave

Dissertations, Theses, and Capstone Projects

Many types of neurons act as multimodal signaling centers. Yet, we have only limited insight into the regulation and functional consequences of neuronal co-transmission. For example, dopamine (DA) neurons, whose degeneration causes motor deficits characteristic of Parkinson’s Diseases (PD), communicate with all their targets by DA but only a selective subset of their targets using GABA, Glutamate, and the secreted cell signaling protein Sonic Hedgehog (Shh). It is unknown whether Levo-dopamine (L-Dopa) induced dyskinesia (LIDs), a severely debilitating side effect of DA supplementation in PD, might appear because DA neuron targets are exposed to high DA- but low Shh- signaling …

Parp1-Targeted Radiotherapies, Stephen Jannetti

Dissertations, Theses, and Capstone Projects

Poly-ADP-ribosylation reactions were first reported by Chambon in 1963 as enzymatic activity that increases incorporation of ATP in the presence of nicotinamide mononucleotide. In the decades since that publication, Poly(ADP-ribose)polymerase 1 (PARP1) and the PARP family enzymes have been widely studied. PARP enzymes are currently known to play various roles in mammals, including anti-aging processes, interactions with Breast Cancer Suppressor Protein-1 (BRCA1), and DNA damage repair. A significant focus of PARP1 research has been elucidating its role in DNA damage repair. PARP1 is recruited to repair single strand DNA (ssDNA) breaks, which can become double stranded DNA (dsDNA) breaks if …

Functional Significance Of Endothelial Sigma-1 Receptors In Vascular Reactivity And Barrier Function, Zeinab Y. Motawe

USF Tampa Graduate Theses and Dissertations

The sigma-1 receptor (σ1) is a single 25 kD polypeptide that acts as a chaperone protein residing primarily in the endoplasmic reticulum Its interaction with mitochondria at the mitochondria-associated ER membrane domain is well-documented. Following activation, σ1 binds to the inositol trisphosphate receptor (Hayashi & Su), and modulates intracellular calcium homeostasis. Also, the activated σ1 modulates plasma membrane receptors and ion channel functions, and may regulate cellular excitability. Further, σ1 affects trafficking of lipids and proteins essential for neurotransmission, cell growth and motility. Activation of σ1 provides neuroprotection and cardio-protection in various models. Examples of neuroprotection include but not limited …

Sepsis and septic shock threaten the survival of millions of patients in the intensive care unit. Secondary fungal infections significantly increased the risk of mortality in sepsis patients. Chinese medicine Xuebijing injection (XBJ) has been routinely used as an add-on treatment to sepsis and septic shock in China. Our network pharmacology analysis predicted that XBJ also influences fungal infection, consisting with results of pioneer clinical studies. We conducted in vivo and in vitro experiments to verify this prediction. To our surprise, XBJ rescued mice from lethal Candida sepsis in a disseminated Candida albicans infection model and abolished the colonization of …

Does Preimplantation Genetic Testing Increase The Risk Of Adverse Clinical Outcomes?, Robyn Weiss

The Science Journal of the Lander College of Arts and Sciences

Before 1990, options were limited for couples who were at risk for transmitting a genetic disease or a structural chromosomal abnormality to their children. Couples traditionally underwent invasive procedures such as amniocentesis and chorionic villus sampling, after which termination was offered if the fetus was found to be affected. Many couples chose not to have children at all. Since then, technological advances have allowed preimplantation genetic testing (PGT) to be offered to these couples. Couples who choose PGT undergo in-vitro fertilization (IVF) with intracytoplasmic sperm injection (ICSI), where the oocyte is injected by a single sperm and is then implanted …

Mechanisms Of Dopamine-Induced Methamphetamine Neurotoxicity, Melinda L. Asbury

Theses, Dissertations and Capstones

Methamphetamine (MA) neurotoxicity is particularly evident in the striatum where it causes extensive dopamine (DA) release and results in neurodegeneration. To identify specific signaling pathways and macromolecules involved in postsynaptic DA-induced striatal toxicity we used a SK-N-MC cell model that mimics postsynaptic D1 receptor-expressing striatal neurons. The cells were treated for 6-24 h with 0-50 µM DA. The concentration was chosen to impart physiological relevance to the study as it mirrors [DA] found within the striatum following MA exposure. We show that 25-50 µM DA resulted in protein changes consistent with nitro(oxidative) stress as well as enhanced cleavage of caspase …

While this method is not a new one, it is constantly being explored and studied to determine if it can be an effective way to treat patients with different bowel diseases. The main target of most of these studies are patients with recurrent Clostridium difficile infections. Many studies were done to determine if the method is safe, and which method is most effective, as well as who can be a good donor or recipient …

Is Pnc-27 And Pnc-28 The Best Way To Cure Cancer?, Miriam Silberstein

The Science Journal of the Lander College of Arts and Sciences

Immunotherapeutic agents have been researched for many decades as an alternative treatment for cancer. Current research demonstrates that immunotherapy is safer than radiotherapy or chemotherapy. This is attributed to immunotherapy’s mechanism of utilizing the body’s own defense system, as opposed to absorbing harmful chemicals. Two forms of immunotherapy that have been effective in curing cancer without the added danger of chemical toxicity are PNC-27 and PNC-28. These peptides were created by a supercomputer at SUNY Downstate Medical Center in New York in 2000. PNC-27 and PNC-28 work with the MDM2 -P53 tumor suppressor complex. It acts as a competitive inhibitor …

Causes And Mechanisms Of Crohn’S Disease, Chana Weis

The Science Journal of the Lander College of Arts and Sciences

Crohn’s disease and ulcerative colitis are the two most prevalent inflammatory bowel diseases (IBDs) in Jewish and Caucasian populations, affecting as many as one in 250 individuals. Nevertheless, the underlying causes of both disorders are not yet fully understood and remain unknown. However, current evidence suggests that the exaggerated inflammatory response, more commonly referred to as IBD, is believed to arise from dysregulation of the gastrointestinal (GI) immune system in genetically predisposed individuals who are exposed to environmental triggers. Recent advances have identified multiple IBD susceptibility genes; however, only a few environmental determinants of IBD have been consistently identified. The …
