This article describes the multiple techniques employed in the reconstruction, analysis, and fitting of the data to measure the precession frequency. It …

Development Of Miriplatin-Loaded Nanoparticles Against Non-Small Cell Lung Cancer, Zhongyue Yuan, Zizhao Xu, Xin Guo

Graduate and Professional Student Research Showcase

Lung cancer claims the highest mortality and the second-most new cases among all oncological diseases. NSCLC accounts for approximately 85% of all newly diagnosed lung cancers. Although platinum-based drugs are standard first-line chemotherapy for stage IIIB/IV NSCLC, accumulating reports have shown the failure of conventional platinum-based regimens due to drug resistance. Miriplatin is a lipophilic anti-cancer drug that has been approved in Japan for transcatheter arterial chemoembolization treatment of hepatocellular carcinoma. Lipid-based nanoparticles such as liposomes, micelles, and solid lipid nanoparticles (SLNs) can encapsulate anti-cancer drugs to improve their water solubility and bioavailability.

Beam Dynamics Corrections To The Run-1 Measurement Of The Muon Anomalous Magnetic Moment At Fermilab, T. Albahri, A. Anastasi, K. Badgley, S. Baeßler

Faculty and Student Publications

This paper presents the beam dynamics systematic corrections and their uncertainties for the Run-1 dataset of the Fermilab Muon g-2 Experiment. Two corrections to the measured muon precession frequency ωam are associated with well-known effects owing to the use of electrostatic quadrupole (ESQ) vertical focusing in the storage ring. An average vertically oriented motional magnetic field is felt by relativistic muons passing transversely through the radial electric field components created by the ESQ system. The correction depends on the stored momentum distribution and the tunes of the ring, which has relatively weak vertical focusing. Vertical betatron motions imply that the …

Chronic Administration Of Pharmacological Doses Of Angiotensin 1-7 And Iodoangiotensin 1-7 Has Minimal Effects On Blood Pressure, Heart Rate, And Cognitive Function Of Spontaneously Hypertensive Rats, Filipe F. Stoyell-Conti, Alesa Chabbra, Joseph Puthentharayil, Katya Rigatto, Robert C. Speth

HPD Articles

Cardiovascular diseases are the principal cause of death worldwide, with hypertension being the most common cardiovascular disease risk factor. High blood pressure (BP) is also associated with an increased risk of poor cognitive performance and dementia including Alzheimer's disease. Angiotensin 1-7 (Ang 1-7), a product of the renin-angiotensin system (RAS), exhibits central and peripheral actions to reduce BP. Recent data from our lab reveals that the addition of a non-radioactive iodine molecule to the tyrosine in position 4 of Ang 1-7 (iodoAng 1-7) makes it ~1000-fold more potent than Ang 1-7 in competing for the I-Ang 1-7 binding site (Stoyell-Conti …

Genetic Mechanisms Of Transcriptional Regulation In Childhood Acute Lymphoblastic Leukemia, Xujie Zhao

Theses and Dissertations (ETD)

Introduction. Advances in genomic profiling and sequencing studies have identified germline and somatic variations that are associated with childhood ALL, improving our understanding of the genetic basis of childhood acute lymphoblastic leukemia (ALL). Recent genome-wide association studies (GWAS) have identified germline genetic variations of ARID5B and, more recently, IGF2BP1 that are associated with susceptibility to ALL. Genome-wide sequencing studies also discovered a new ALL subtype characterized of ZNF384-mediated chromosomal translocations, providing new insights into genetic heterogeneity in childhood ALL. However, the underlying mechanism by which these genetic variants contribute to the transcriptional regulatory circuitries of ALL is still poorly understood. …

Methamphetamine-Induced Changes In Myocardial Gene Transcription Are Sex-Dependent, Hasitha Chavva, Daniel A. Brazeau, James Denvir, Donald A. Primerano, Jun Fan, Sarah L. Seeley, Boyd R. Rorabaugh

Pharmaceutical Science and Research

Background: Prior work demonstrated that female rats (but not their male littermates) exposed to methamphetamine become hypersensitive to myocardial ischemic injury. Importantly, this sex-dependent effect persists following 30 days of subsequent abstinence from the drug, suggesting that it may be mediated by long term changes in gene expression that are not rapidly reversed following discontinuation of methamphetamine use. The goal of the present study was to determine whether methamphetamine induces sex-dependent changes in myocardial gene expression and whether these changes persist following subsequent abstinence from methamphetamine.

Results: Methamphetamine induced changes in the myocardial transcriptome were significantly greater in female hearts …

Design And Synthesis Of Macrocyclic Peptide Braf-Wt Dimerization Inhibitors For The Treatment Of Metastatic Melanoma, Chad Mulloy Beneker

Theses and Dissertations

In cases of metastatic melanoma, BRAF is frequently mutated to the V600E oncoprotein causing uncontrolled cell proliferation driven by the MAPK-ERK pathway. There are several BRAF inhibitors, such as vemurafenib, which are FDA approved, but patients treated with these Type-I kinase inhibitors frequently observe relapse under mutant RAS and BRAF-wt conditions due to paradoxical activation. The mechanism of this resistance occurs through binding of the inhibitor to BRAF-wt initiating conformational changes which leads to BRAF dimerization. Once in the dimerized state, the inhibited monomer induces allosteric transactivation of the second monomer. This drug-induced activation of BRAF in cells with mutant …

Pharmacological Blockade Of The 20-Hete Receptor Lowers Blood Pressure And Alters Vascular Function In Mice With Vascular Smooth Muscle- Specific Overexpression Of Cyp4a12-20-Hete Synthase, Kevin Agostinucci

NYMC Student Theses and Dissertations

20-hydroxyeicosatetraenoic acid (20-HETE) is the ω-hydroxylation product of arachidonic acid catalyzed by CYP4A and 4F enzymes. 20-HETE is a vasoactive eicosanoid of the microcirculation exhibiting effects on both vascular smooth muscle cells (VSMC) and endothelial cells (EC). In VSMCs, 20-HETE’s bioactions include the stimulation of contraction, migration, and growth. In ECs, elevated 20-HETE is associated with reduced nitric oxide (NO) bioavailability, increased angiotensin converting enzyme (ACE) expression, and the promotion of inflammation. Recently in our laboratory, we identified GPR75 as a novel target of 20-HETE that promotes changes in blood pressure and vascular function. The aim of this study is …

Data For "Subtype-Selective Positive Modulation Of Sk Channels Depends On The Ha/Hb Helices", Miao Zhang, Meng Cui

Pharmacy Faculty Data Sets

In the activated state of small-conductance Ca²⁺-activated potassium (SK) channels, calmodulin interacts with the HA/HB helices and the S4-S5 linker. CyPPA potentiates SK2a and SK3 channel activity but not the SK1 and IK subtypes. Here, we report that the subtype-selectivity of CyPPA relies on the HA/HB helices. Mutating residues in the HA (V420) and HB (K467) helices of SK2a channels to their equivalent residues in IK channels diminished the potency of CyPPA. CyPPA elicited prominent responses on mutant IK channels with an arginine residue in the HB helix substituted for its equivalent lysine residue in the SK2a channels …
