Cocoa Polyphenols Modulate The Fecal Microbiome In A Mouse Model Of Colitis, Independent Of Basal Diet And Colon Inflammation, Abby D. Benninghoff

Browse all Datasets

Chronic inflammation increases the risk of developing multiple chronic diseases, including cancer. The risk of developing colorectal cancer (CRC) specifically is increased in individuals who suffer from colitis, a characteristic of Inflammatory Bowel Disease (IBD). Diet is another risk factor for developing CRC, particularly an inflammation-promoting Western-type diet. Thus, supplementing a Western diet with functional foods containing anti-inflammatory polyphenols is a potential approach to decreasing CRC risk by reducing gut inflammation and altering gut microbiome profile. This study aimed to determine the effects of cocoa polyphenol (CP) supplementation on inflammation status and microbiome profile before, during, and after colitis when …

Quantitative Raman Analysis Of Human Blood Serum Of Glaucoma Patients Supplemented With Macular Pigment Carotenoids., Joy Udensi, Ekaterina Loskutova, James Loughman, Hugh J. Byrne

Datasets

Carotenoids have been widely studied for their high dietary, antioxidant, and vision protection roles in the human body. Blood contains all major dietary carotenoids and hence presents as a suitable and efficient substrate for the estimation of dietary carotenoids in vivo. Following the 18-month supplementation of open angle glaucoma patients with macula pigment carotenoids (Lutein, Zeaxanthin and Meso-Zeaxanthin) in the European Nutrition in Glaucoma Management (ENIGMA) trial, Raman spectroscopic analysis of the pre-supplementation baseline and 18-month supplemented blood serum carotenoids from participants was carried out, to investigate the systemic impact of supplementation in the blood and explore a more direct …

Fluorescent Peptide For Detecting Factor Xiiia Activity And Fibrin In Whole Blood Clots Forming Under Flow, Yue Liu, Jennifer Crossen, Timothy J. Stalker, Scott L. Diamond

Cardeza Foundation for Hematologic Research

Background

During clotting, thrombin generates fibrin monomers and activates plasma-derived transglutaminase factor (F) XIIIa; collagen and thrombin-activated platelets offer thrombin-independent cellular FXIIIa (cFXIIIa) for clotting. Detecting fibrin on collagen and tissue factor surfaces in whole blood clotting typically uses complex reagents like fluorescent fibrinogen or antifibrin antibody.

Objectives

We want to test whether the peptide using the α2- antiplasmin crosslinking mechanism by FXIIIa is a useful tool in both monitoring FXIIIa activity, and visualize and monitor fibrin formation, deposition, and extent of crosslinking within fibrin structures in whole blood clots formed under flow.

Methods

We tested a fluorescent peptide derived …

Nonlinear Model Predictive Control Of Vagal Nerve Stimulation To Regulate Hemodynamic Variables, Oluwasanmi Adeodu, Michelle Gee, Babak Mahmoudi, Rajanikanth Vadigepalli, Mayuresh Kothare

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Various pre-clinical investigations indicate that the electrical stimulation of the cervical branch of the vagus that innervates the heart has therapeutic value in the management of various cardiac diseases. In theory, the design of a closed-loop control mechanism that automatically adjusts vagal nerve stimulation (VNS) parameters based on real-time physiological feedback can eliminate intra-patient variability in VNS outcomes and therefore represents a major step towards patient-specific therapy. This study develops a nonlinear model predictive control (NMPC) approach for VNS of a pulsatile, human cardio-baroreflex system. The manipulated variables are the frequency and amplitude of a charge-balanced biphasic current. The effects …

Pharmacoeconomics Of Metastatic Colorectal Cancer Treatment With Targeted Therapies Guided By Companion Molecular Diagnostics, Luis E. Fernández-Garza, Hector Sánchez-Ibarra, Daniela Treviño-Sáenz, Hugo A. Barrera-Saldaña

Research Symposium

Background: To guide the treatment with monoclonal antibodies (MAbs) against the epidermal growth factor receptor (EGFR) of metastatic colorectal cancer (mCRC), the FDA recommends prior companion molecular diagnosis (CMDx). It initially recommended screening for mutations in exon 2 of the KRAS gene, and most recently to extend to screening to exons 2, 3, and 4 of KRAS and 2, 3, and 4 of NRAS genes; furthermore, to evaluate the BRAF exon 15 mutation status (including V600E). To date, no studies have been done to compare the cost-benefit of these different CMDXs.

Methods: We have compared the cost of treatment without …

Increasing Opioid Overdose Among Hispanic Young Population In The Borders Of The Usa And Mexico. Imperative To Work With First Responders And Proper Use Of Narcan, Denis X. Gutierrez, B Oluwakemi, N. Patel, Nevin A. Varghese

Research Symposium

Background: Hypercapnic respiratory failure is a frequently encountered medical emergency. A very common cause among young patients is a side effect of opioids in the setting of an opioid crisis in both sides of the borders. Sometimes a delay in diagnosis associated with increased synthetic opioids use causes a delay in optimal management. We report a case of a patient that was negative for opioids in urine but responded to repeated dose of Narcan, the family later explained that he was obtaining medications across the border and distributing drugs.

Case presentation: 21 y/o Hispanic man who lives at a border …

METHODS: From Nov 7, 2021, to Feb 24, 2022, we conducted a public health investigation involving 15 agencies and medical centres in the USA. We tested various specimens (blood, cerebrospinal fluid, intraocular fluid, serum, and tissues) from the organ donor and recipients by serology, RT-PCR, immunohistochemistry, metagenomic next-generation sequencing, and host gene expression, and conducted a traceback of blood transfusions received by …

C9orf72 Poly(Pr) Mediated Neurodegeneration Is Associated With Nucleolar Stress, M. E. Cicardi, J. H. Hallgren, D. Mawrie, K. Krishnamurthy, S. S. Markandaiah, A. T. Nelson, V. Kankate, E. N. Anderson, P. Pasinelli, U. B. Pandey, C. M. Eischen, D. Trotti

Farber Institute for Neuroscience Faculty Papers

The ALS/FTD-linked intronic hexanucleotide repeat expansion in the C9orf72 gene is aberrantly translated in the sense and antisense directions into dipeptide repeat proteins, among which poly proline-arginine (PR) displays the most aggressive neurotoxicity in-vitro and in-vivo. PR partitions to the nucleus when heterologously expressed in neurons and other cell types. We show that by lessening the nuclear accumulation of PR, we can drastically reduce its neurotoxicity. PR strongly accumulates in the nucleolus, a nuclear structure critical in regulating the cell stress response. We determined that, in neurons, PR caused nucleolar stress and increased levels of the transcription factor p53. …

Gene Signature Reveals Decreased Sox10-Dependent Transcripts In Malignant Cells From Immune Checkpoint Inhibitor-Resistant Cutaneous Melanomas, Timothy J. Purwin, Signe Caksa, Ahmet Sacan, Claudia Capparelli, Andrew E. Aplin

Department of Pharmacology, Physiology, and Cancer Biology Faculty Papers

Evidence is mounting for cross-resistance between immune checkpoint and targeted kinase inhibitor therapies in cutaneous melanoma patients. Since the loss of the transcription factor, SOX10, causes tolerance to MAPK pathway inhibitors, we used bioinformatic techniques to determine if reduced SOX10 expression/activity is associated with immune checkpoint inhibitor resistance. We integrated SOX10 ChIP-seq, knockout RNA-seq, and knockdown ATAC-seq data from melanoma cell models to develop a robust SOX10 gene signature. We used computational methods to validate this signature as a measure of SOX10-dependent activity in independent single-cell and bulk RNA-seq SOX10 knockdown, cell line panel, and MAPK inhibitor drug-resistant datasets. Evaluation …

Spinal and bulbar muscular atrophy (SBMA) is a neuromuscular disease with substantial mitochondrial and metabolic dysfunctions. SBMA is caused by polyglutamine (polyQ) expansion in the androgen receptor (AR). Activating or increasing the NAD+-dependent deacetylase, SIRT3, reduced oxidative stress and death of cells modeling SBMA. However, increasing diminished SIRT3 in AR100Q mice failed to reduce acetylation of the SIRT3 target/antioxidant, SOD2, and had no effect on increased total acetylated peptides in quadriceps. Yet, overexpressing SIRT3 resulted in a trend of motor recovery, and corrected TCA cycle activity by decreasing acetylation of SIRT3 target proteins. We sought to boost blunted SIRT3 activity …

Diastrophic dysplasia (DTD) is a recessive chondrodysplasia caused by pathogenic variants in the SLC26A2 gene encoding for a cell membrane sulfate/chloride antiporter crucial for sulfate uptake and glycosaminoglycan (GAG) sulfation. Research on a DTD animal model has suggested possible pharmacological treatment approaches. In view of future clinical trials, the identification of non-invasive biomarkers is crucial to assess the efficacy of treatments. Urinary GAG composition has been analyzed in several metabolic disorders including mucopolysaccharidoses. Moreover, the N-terminal fragment of collagen X, known as collagen X marker (CXM), is considered a real-time marker of endochondral ossification and growth velocity and was studied …
