Nitric oxide (NO) is a key gasotransmitter that binds to soluble guanylate cyclase (sGC), thereby stimulating cGMP production. Under disease conditions, reactive oxygen species disrupt this signaling by either: (1) scavenging NO, or (2) promoting heme-free, NO-insensitive apo-sGC due to impaired heme incorporation or oxidative damage. To counteract these conditions, two pharmacological approaches have emerged: sGC stimulators, which allosterically enhance sGC sensitivity to low NO levels; and sGC activators, which directly activate apo-sGC (heme-free sGC) by binding to its empty heme pocket, inducing a conformation that mimics NO-bound sGC. Thus, sGC stimulators are thought to target only sGC. Instead, we …

A Urine-Based Point-Of-Care Test For Factor Xa Inhibitors In Acute Stroke Management, Prasen R Marella, Jacob A Sambursky, Kriti Bhayana, Asha P Jacob, Varsha Muddasani, Murli Mishra, Alexandra L Czap, James C Grotta

Faculty, Staff and Student Publications

Background: For stroke patients with history of possible Direct Acting Oral Anticoagulant use, clinicians must make treatment decisions without knowledge of whether the patient is therapeutically anticoagulated. A urine-based point-of-care test might help guide these emergency decisions.

Methods: We prospectively enrolled patients with suspected recent factor-Xa-inhibitor (Xai) use being evaluated for acute stroke therapy in an urban teaching hospital. We obtained the urine test and plasma anti-Xa level in parallel with usual clinical management; the treating clinician did not use test results for decision-making but recorded treatment they would have given had they known the urine test was accurate. The …

Effective Transfer Of Tumor Annotations From Hematoxylin And Eosin To Fluorescence Images Of Breast And Lung Tissues, Tianling Niu, Emi Ampo, Julie M. Jorns, Mollie Patton, Tongtong Lu, Dong Hye Ye, Tina Yen, Bing Yu

Biomedical Engineering Faculty Research and Publications

Significance: Accurate transfer of annotations from histological images to fluorescence images is essential in developing deep learning (DL)-based optical imaging systems for intraoperative assessment of tumor margins. Manual annotation is time-consuming, prone to interobserver variability, and impractical for large-scale datasets.

Aim: We present a semi-automated method that can effectively transfer tumor annotations from pathologist-annotated hematoxylin and eosin (H&E) images to fluorescence images captured using microscopy with ultraviolet surface excitation (MUSE). This method is not intended for intraoperative use but rather to facilitate the creation of annotated datasets for DL model development.

Approach: Our semi-automated method consists of nonrigid image registration, …

Faculty, Staff and Student Publications

Background: Matrix metalloproteinase 7 (MMP-7) is a novel biomarker for diagnosis of biliary atresia (BA), the most common cholestatic liver disease in infancy. There is a pressing need to determine the utility of MMP-7 levels in infants with congenital heart disease (CHD) to avoid unnecessary invasive diagnostic procedures in this high-risk population. We investigated the utility of MMP-7 in discriminating BA from non-BA cholestasis in infants with CHD and whether MMP-7 elevation was present in infants requiring treatment for clinically significant PH.

Methods: This is a single-center cross-sectional study including infants < 180 days of age with cholestasis and serum MMP-7 levels collected from 2019 to 2023. Demographic data and descriptive statistics were summarized with medians with interquartile ranges and frequencies with percentages. Median MMP-7 levels were assessed via Wilcoxon rank-sum test.

Results: A total of 149 patients were included. Patients …

Pancreatic Cancer-Related Diabetes And Type 2 Diabetes Differ In Multiple Aspects Of Glucose Homeostasis, Frederico G S Toledo, Yisheng Li, Fuchenchu Wang, Melena D Bellin, Randall Brand, Kenneth Cusi, William Fisher, Yogish C Kudva, Walter G Park, Zeb I Saeed, Dhiraj Yadav, Robert V Considine, Sarah C Graham, Dana K Andersen, Jose Serrano, Mark O Goodarzi, Phil A Hart

Faculty, Staff and Student Publications

Aims/hypothesis: Pancreatic ductal adenocarcinoma-related diabetes mellitus (PDAC-DM) is a paraneoplastic syndrome with a poorly understood pathophysiology. PDAC-DM is often clinically confused with type 2 diabetes, resulting in delayed cancer detection and poorly individualised hyperglycaemia treatment. We investigated whether these forms of diabetes can be distinguished at the metabolic level.

Methods: Adults with either cancer treatment-naive PDAC-DM (n=28) or type 2 diabetes (n=97), and with diabetes onset within 3 years, underwent mixed-meal tolerance tests to investigate glucose metabolism. Outcomes included insulin sensitivity (Matsuda index), insulin secretion (insulinogenic index), beta cell function (oral disposition index), insulin clearance, and postprandial glucagon, glucagon-like peptide-1 …

In this study, we evaluated the association between mortality and boarding time in patients presenting at an oncologic ED.

Methods: This retrospective study included all ED visits for patients aged ≥19 years who presented to The University of Texas MD Anderson Cancer Center ED between March 3, 2016 and December 31, 2022, with a disposition of hospital admission. Univariate and multivariable logistic regression …

Bayesian Integrated Learning Of Longitudinal Dose-Response Relationships Via Decentralized Clinical Trials, Jingyi Zhang, Tuo Wang, Yongming Qu, Fangrong Yan, Suyu Liu, Ruitao Lin

Faculty, Staff and Student Publications

Decentralized clinical trials (DCTs) extend trial activities beyond traditional sites, enhancing access, convenience, efficiency, and result generalizability. They are particularly promising for chronic conditions like diabetes and obesity, which require longer study durations to evaluate drug effects. However, decentralized data collection raises concerns about increased variability and potential biases. This paper presents a novel Bayesian integrated learning procedure to analyze dose-response relationships using longitudinal data from a phase II DCT that combines centralized and decentralized data collection. We generalize a parametric exponential decay model to handle mixed data sources and apply Bayesian spike-and-slab priors to address biases and uncertainties from …

Faculty, Staff and Student Publications

Background: Muscular strength is a powerful marker of current health status and robust predictor of age-related disease and disability. Handgrip strength (HGS) using isometric dynamometry is a convenient, feasible, and widely used method of assessing muscular strength among people of all ages. While adult HGS norms have been published for many countries, no study has yet synthesized available data to produce international norms. The objective of this study was to generate international sex- and age-specific norms for absolute and body size-normalized HGS across the adult lifespan.

Methods: Systematic searches were conducted in 6 databases/web search engines (MEDLINE, SPORTDiscus, Embase, Web …

Benzodioxane-Benzamides Targeting Bacterial Cell Division Protein Ftsz Potentially Disrupt Slma-Mediated Nucleoid Occlusion And Reversible Biomolecular Condensation, Marta Sobrinos-Sanguino, Inés Barros-Medina, Lorenzo Suigo, Alessia Lanzini, Ermanno Valoti, William Margolin, Valentina Straniero, Begoña Monterroso, Silvia Zorrilla

Faculty, Staff and Student Publications

New strategies are urgently needed against antimicrobial resistance, a major health threat, and the different mechanisms regulating the bacterial cell division machinery offer multiple opportunities for developing novel therapeutics. FtsZ, an essential protein of this process, is targeted by multiple small molecules, and benzodioxane-benzamides (BDOBs) are among the most potent inhibitors in several bacterial species. BDOBs mechanisms are however poorly understood, particularly their impact on FtsZ's interplay with partners and ability to assemble phase-separated biomolecular condensates potentially involved in stress sensing. We show that certain BDOBs shielded FtsZ against depolymerization induced by the nucleoprotein complexes of SlmA, which inhibit Z-ring …

Reviewing Vascular Influences On Neuronal Migration, Cortical Development, And Neurodevelopmental Disorders: Focus On Autism, Adhd And Schizophrenia, Lalit K Ahirwar, Spiros L Blackburn, Devin W Mcbride, Peeyush Kumar T

Faculty, Staff and Student Publications

During cortical development, newly born neurons migrate radially or tangentially from their origin to expand the cortex. Simultaneously, neuron-derived factors support angiogenesis, and an elaborate network of blood cerebral vessels develops in the cortex. Traditionally, blood cerebral vessels were considered to support the growing cortex or migrating neurons by providing nutrients and oxygen. However, recent studies have shed light on Endothelial cells' influence on cortical development; they guide neuronal migration by providing molecular cues and structural support. Here, we review the current understanding of how CNS cerebral vessels support neurogenesis, neuronal migration, and the formation of the six-layer cortical structure …

Relative Biological Effectiveness-Clinical Practice At Us Proton Therapy Centers, Armin Lühr, Radhe Mohan, Anita Mahajan, Helen A Shih, Harald Paganetti

Faculty, Staff and Student Publications

Purpose: Proton therapy, with its high conformality and superior dose distribution, is becoming an increasingly prevalent modality in radiation oncology. Although a generic relative biological effectiveness (RBE) value of 1.1 for treatment planning has been adopted, evidence suggests that RBE varies with dose, linear energy transfer (LET), and biological endpoints. This variation raises concerns about underestimating the RBE-weighted dose, which may significantly impact treatment outcomes. To assess the awareness and management of RBE variability in clinical practice, we conducted a survey among US proton therapy centers.

Materials and methods: The survey consisted of 32 questions grouped into subtopics, such as …

Personalized Risk Prediction For Cancer Survivors: A Generalized Bayesian Semi-Parametric Model Of Recurrent Events With Competing Outcomes, Nam Hoai Nguyen, Seung Jun Shin, Elissa Dodd-Eaton, Jing Ning, Wenyi Wang

Faculty, Staff and Student Publications

Multiple primary cancers are increasingly more frequent due to improved survival of cancer patients. Characteristics of the first primary cancer largely impact the risk of developing subsequent primary cancers. Hence, model-based risk characterization of cancer survivors that captures patient-specific variables is needed for healthcare policy making. We propose a Bayesian semi-parametric framework, where the occurrence processes of the competing cancer types follow independent non-homogeneous Poisson processes and adjust for covariates including the type and age at diagnosis of the first primary. Applying this framework to a historically collected cohort with families presenting a highly enriched history of multiple primary tumors …

Introduction: Immunotherapy is firmly established as a treatment regimen in various solid tumors, driven by its exceptional benefits in a selected group of patients. Despite widespread adoption of immune checkpoint blockade (ICB) across diverse solid tumors, the quest for a clinically informative biomarker for long-term benefit remains unmet.

Methods: A total of 49 patients with metastatic NSCLC treated with ICB were included. Long-term (LTR) and short-term responders (STR) were defined as those with a response to ICB lasting more than 24 months or less than 6 months, respectively. Longitudinal blood specimens were collected before ICB treatment initiation and early-on treatment. …

Normalization Of Temperature Effects For Quality Assurance Of Quantitative Prostate Apparent Diffusion Coefficient Imaging Across Multiple Sites, Ken-Pin Hwang, Joshua Yung, R Jason Stafford, Caroline Chung, Aradhana M Venkatesan

Faculty, Staff and Student Publications

Background: Apparent Diffusion Coefficient (ADC) as measured by diffusion weighted imaging is known to negatively correlate with prostate tumor aggressiveness. Heterogeneity in system and protocol performance causes potential variability in ADC acquired across a large scanner network, prompting a need to evaluate quantitative ADC from a prostate-specific MR diffusion protocol as part of quality assurance (QA). Due to the temperature dependence of ADC, repeatability and reproducibility assessments typically require phantoms to maintain a temperature of 0°C, imposing a considerable burden when assessing large numbers of scanners.

Purpose: To develop a QA procedure at room temperature for assessing the reproducibility of …

Caspase 3-Specific Cleavage Of Ubiquitin-Specific Peptidase 48 Enhances Drug-Induced Apoptosis In Aml, Zhanglin Zhang, Xiang Lin, Yaling Yang, Xuemei Wang, Yi Wang, Xianbao Huang, Miao Hong, Wei Gao, Hua He, M James You, Yi Yang, Guangyao Kong

Faculty, Staff and Student Publications

Dysfunction or dysregulation of deubiquitination is closely related to the initiation and development of multiple cancers. Targeted regulation of deubiquitination has been recognized as an important strategy in tumor therapy. However, the mechanism by which drugs regulate deubiquitinase is not clear. Here, we identified ubiquitin-specific peptidase 48 (USP48), a member of the ubiquitin-specific protease family highly expressed in various tumors, as a specific substrate for the activated caspase-3. During drug induced apoptosis of AML cells, activated caspase-3 cleaves USP48 through recognizing the conservative motif DEQD located at 611-614 sites of human USP48. Subsequent analysis showed that the cleavage USP48 N-terminal …

SARS-CoV-2 is the betacoronavirus causing the COVID-19 pandemic. Although the SARS-CoV-2 genome and transcriptome were reported previously, the function of individual viral proteins is largely unknown. Utilizing biochemical and molecular biology methods, we identified that four SARS-CoV-2 RNA-binding proteins (RBPs) regulate the host RNA metabolism by direct interaction with mature miRNA let-7b revealed by Nuclear Magnetic Resonance spectroscopy (NMR). SARS-CoV-2 RBP Nsp9 primarily binds mature miRNA let-7b, a direct ligand of the Toll-like Receptor 7 (TLR7), one of the potential SARS-CoV-2 therapeutics. Nsp9 suppresses host gene expression possibly by promoting let-7b-mediated silencing of a cellular RNA polymerase, POLR2D. In addition, …

Impact Of Peripheral Circadian Misalignment And Alcohol On The Resiliency Of Intestinal Barrier And Microbiota, Laura Tran, Maliha Shaikh, Phillip A Engen, Ankur Naqib, Dulce M Frausto, Vivian Ramirez, Malia Gasteier, Zlata Bogin, Kristi Lawrence, Lijuan Zhang, Shiwen Song, Stefan J Green, Faraz Bishehsari, Christopher B Forsyth, Ali Keshavarzian, Garth R Swanson

Faculty, Staff and Student Publications

Circadian organization is involved in many gastrointestinal tract (GIT) functions such as the maintenance of intestinal barrier integrity. There is compelling evidence that perturbation of the circadian clock decreases intestinal epithelial cells' resiliency to alcohol-induced injury. One of the most common causes of circadian misalignment is wrong-time eating (largest meal at dinner) in modern societies. Yet, few studies have examined the importance of peripheral circadian rhythms of the GIT to alcohol consumption. Eating patterns during physiologic rest time, defined as wrong-time eating (WTE), misalign the peripheral circadian clock of the GIT and the body's central clock. This study aims to …

Fecal Microbiota Transplant (FMT) is a treatment for recurrent Clostridium difficile infections and is being explored for other clinical applications, from alleviating digestive and neurological disorders, to restoring microbiomes impacted by cancer treatment. Quantifying the extent of engraftment following an FMT is important in understanding a recipient's response to treatment. Engraftment and clinical response need to be investigated independently to evaluate an FMT's role (or lack thereof) in achieving a clinical response. Standardized bioinformatics methodologies for quantifying engraftment extent would not only improve assessment and understanding of FMT outcomes, but also facilitate comparison of FMT results and protocols across studies. …

The Role Of Neutrophils In Vasospasm And Delayed Cerebral Ischemia After Aneurysmal Subarachnoid Hemorrhage: Is It Time For A Sah Clinical Trial Targeting Neutrophils?, William W Wroe, Hussein A Zeineddine, Spiros L Blackburn, Jaroslaw Aronowski, Devin W Mcbride

Faculty, Staff and Student Publications

Aneurysmal subarachnoid hemorrhage (aSAH) is a devastating neurological disease, and one of the primary drivers of morbidity after aneurysm rupture is the phenomenon of delayed cerebral ischemia (DCI). Significant knowledge has been gained over the past two decades of the impact of neuroinflammation in DCI; and neutrophils are now believed to play a major role. There is significant human subject data showing the rise of neutrophil related inflammatory markers and neutrophil's association with poor outcome after aSAH, but as of yet no trials involving human subjects have been done specifically targeting neutrophils. There is however a growing body of evidence …

Statistical Innovations In Clinical Trial Design With A Focus On Drug Combinations, Factorials, And Other Multiple Therapy Issues, Donald A Berry

Faculty, Staff and Student Publications

Statistical methods in clinical research tend to become entrenched. Innovations threaten the status quo. The "right way" becomes frozen in lore. This is so even when the "right way" is not best. "Statistical significance" and the associated requirement of "high power" is an example. This attitude is an impediment to efficient design. Willingness to address some design issues with moderate power enables building highly informative and highly efficient clinical trials. This article considers several types of clinical trials, including dose-finding, combinations, and factorial designs. Bayesian adaptive methods are used to show that trials can be made more efficient and more …

Does Reducing Videofluoroscopy Frame Rate Affect Dige/St Grades In Modified Barium Swallow Studies?, Shitong Mao, Carla L Warneke, Sheila N Buoy, Ariana J Sahli, Brinda Rao Korivi, Carly E A Barbon, Kristy K Brock, Katherine A Hutcheson

Faculty, Staff and Student Publications

Understanding the effects of reduced frame rates on the reliability of Modified Barium Swallow (MBS) ratings for swallowing safety and efficiency is essential for clinical practice. While previous research has examined frame rate (simulated pulse rates) implications concerning penetration, aspiration, and residue ratings, the impact on summary grading systems like the Dynamic Imaging Grade of Swallowing Toxicity (DIGEST) remains unclear. This study analyzed a total of 315 full MBS videos collected from 278 patients, and 76.25% of patients were diagnosed with head and neck cancer (mean age 62.51 years, SD 8.53; 12.23% female). We performed pairwise comparisons of DIGEST grades …
