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 …

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 …

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 …

Department of Biological & Biomedical Sciences

Background: Multiple-drug-resistant Gram-negative bacteria (MDR-GNB)-associated neonatal ventriculitis is a life-threatening complication that needs timely diagnosis and effective treatment with broad-spectrum antimicrobials in critical-care settings. Inadequate penetration of antibiotics through the blood-brain barrier also demands an intraventricular (IVT) route of administration. This study reports mortality and neurodevelopmental sequelae of neonates till 18 months of age, who received IVT-colistin for treating MDR-GNB associated ventriculitis.
Methods: In a case series of seven neonates with ventriculitis due to MDR-GNB at NICU of Aga Khan University Hospital, Pakistan, between June 2015 and 2018, we reviewed IVT-colistin therapy in critically ill neonates. Treatment outcomes were assessed …

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 …

Human Genetics, Psychotropic Drugs, And Acts Of Violence, Selma Jolanda Eikelenboom-Schieveld

Electronic Theses and Dissertations

From the start of the use of psychoactive prescription medications in the 1950s, physicians reported paradoxical adverse reactions, ranging from newly developing depressions to an increase in existing mood disorders, and extremely violent and bizarre acts of suicide and homicide. In this research, it is hypothesized that the pharmacological properties of the prescribed drugs or the interaction between the drugs and the enzymes that are primarily responsible for their metabolism (cytochrome P450s) could cause these reactions. Given that acts of violence could be medication-induced, the role of the rate of drug metabolism is discussed. Genetic testing of certain CYP450s could …

Total Cellular Atp Production Changes With Primary Substrate In Mcf7 Breast Cancer Cells., Maggie Louie, Justin Ton, Maurice L. Brady, Diem T. Le, Jordon N. Mar, Chad A Lerner, Akos A Gerencser, Shona A. Mookerjee

Natural Sciences and Mathematics | Faculty Scholarship

Cancer growth is predicted to require substantial rates of substrate catabolism and ATP turnover to drive unrestricted biosynthesis and cell growth. While substrate limitation can dramatically alter cell behavior, the effects of substrate limitation on total cellular ATP production rate is poorly understood. Here, we show that MCF7 breast cancer cells, given different combinations of the common cell culture substrates glucose, glutamine, and pyruvate, display ATP production rates 1.6-fold higher than when cells are limited to each individual substrate. This increase occurred mainly through faster oxidative ATP production, with little to no increase in glycolytic ATP production. In comparison, non-transformed …

Variations On A Theme: Intricacies Of Unanchored Poly-Ubiquitin Signaling And Toxicity, Jessica Renee Blount-Pacheco

Wayne State University Dissertations

Ubiquitin is an 8.5 kDa post-translational modifier involved in essentially all eukaryotic cellular processes. Through a process called ubiquitination, ubiquitinating enzymes chemically attach ubiquitin to substrate proteins to control their fates, resulting in anything from their recruitment into signaling pathways to their proteasomal degradation, with a plethora of possibilities in between. Ubiquitin molecules can also be attached to one another, resulting in poly-ubiquitin chains with various effects depending on the number of ubiquitin molecules and the specific amino acid residues used to link them together. While most poly-ubiquitin in the cell exists as conjugated species, there are also untethered poly-ubiquitin …
