Clinical Applications Of Topical Platelet-Rich Plasma In Cardiac Surgery: A Scoping Review, Jaron M. Davis

Student Works

Background: Postoperative wound complications persist as a significant challenge within adult cardiac surgery. Deep and superficial sternal wound infections, along with complications at saphenous vein harvest sites, are linked to increased morbidity, extended hospital stays, and substantial healthcare expenses. Topical platelet-rich plasma (PRP), commonly known as platelet gel, has been suggested as a biologically active adjunct that may facilitate tissue repair and mitigate postoperative complications. While PRP has garnered attention in surgical practice, the overall scope and consistency of the supporting evidence in cardiac surgery remain ambiguous.

Objective: The purpose of this scoping review is to map and describe the …

Dasatinib And Quercetin Senolytic Treatment Delays Early Onset Intervertebral Disc Degeneration In Sm/J Mice, Emanuel J. Novais, Olivia K. Ottone, Sanjana Jagannath, Esther Jesutofunmi Akande, Makarand V. Risbud

Department of Orthopaedic Surgery Faculty Papers

Genetic background is a major determinant of disc degeneration, a leading cause of chronic back pain and disability. Herein, we demonstrate that premature disc cell senescence contributes to early-onset degeneration in SM/J mice and test two systemic senotherapeutic strategies to mitigate it: Navitoclax (Nav.) and a cocktail of Dasatinib and Quercetin (DQ). While Nav. treatment did not improve severe degeneration in SM/J mice or senescence status, DQ-treated mice showed lower grades of degeneration and a decreased abundance of senescence markers, including p19ARF, p21, and the senescence-associated secretory phenotype (SASP). DQ improved disc cell viability and phenotype retention and retarded fibrosis …

Acute Compartment Syndrome Following Lower Leg Vascular Injury: A Big-Data Approach To Estimating Incidence And Risk Factors, Harry Moroz, Edward J. Harvey, Yasser C. Bouklouch

Journal of Shock and Hemodynamics

Acute Compartment Syndrome (ACS) is a limb- and life-threatening complication of lower leg fractures. Rapid recognition and fasciotomy can prevent irreversible ischemic injury, but ACS is often under-recognized. Vascular injury may increase the risk of ACS by impairing perfusion and exacerbating swelling. This study aimed to determine the incidence, risk factors, and outcomes of ACS in patients with lower leg fractures, with particular emphasis on the impact of vascular injury. This retrospective cohort study used data from the 2017 American College of Surgeons Trauma Quality Programs database to perform a multicenter analysis of patients with lower leg fractures. Patients were …

Acute Traumatic Aortic Injury: What The Radiologist Needs To Know, Kristina Ramirez-Garcia, Catalina Jaramillo, Emma Ferguson, Jason Au, Erika Odisio, Gustavo S Oderich, Daniel Ocazionez, Cihan Duran, Thanila Macedo

Faculty, Staff and Students Publications

Acute traumatic aortic injury (ATAI) is a rare but life-threatening consequence of blunt trauma that requires prompt diagnosis and accurate imaging assessment. This review presents an imaging-based approach to ATAI, with emphasis on computed tomography angiography (CTA) as the first-line modality for diagnosis, grading, treatment planning, and follow-up. CTA enables the detection of both direct and indirect signs while also allowing for the assessment of lesion severity, extent, and associated findings that may influence management. Familiarity with common mimics and anatomic variants improves diagnostic confidence and helps avoid false positive interpretations. Careful protocol optimization, including multiphasic acquisition, bolus timing, and …

Tandem repeats (TRs) exhibit high levels of somatic mosaicism, which is increasingly recognized as an important modifier of repeat expansion disorders. Long-read sequencing can capture full-length repeat alleles, yet robust frameworks for quantifying instability across TRs genome-wide are still needed. Here, we introduce a general-purpose model for quantifying TR instability in a given long-read sequencing dataset, without explicitly distinguishing biological mosaicism from technical noise, and which is broadly applicable to both simple and structurally complex loci. This model accurately characterizes allelic instability at each TR locus by representing the distribution of read-to-consensus deviations for each allele. Using HiFi sequencing data …

Condensate State As Determinant Of Amyloid Pathology In Neurodegeneration, Lathan Lucas, Josephine C Ferreon, Allan Chris M Ferreon

Faculty, Staff and Students Publications

Neurodegenerative diseases arise when normally functional aggregation-prone proteins transition into stable cross-β amyloid fibrils. Although these fibrils share a conserved architecture, the pathways that lead to fibrillation vary across proteins and cellular environments. Liquid-liquid phase separation is now recognized as a central organizer of intracellular biochemistry that modulates protein aggregation. Physiological condensation can buffer aggregation by maintaining macromolecular solubility and providing partner interactions that compete against pathological protein-protein interactions. However, condensates can transform and age into gel-like states that can favor the emergence of β-rich oligomers and solid-state fibrils. Across six disease-linked proteins that include Tau, α-synuclein, amyloid-β, TDP-43, FUS, …

H3 Dopaminylation And Camkii Modulate Diffuse Midline Glioma Response To Cdk9 Inhibition, Rebecca L Murdaugh, Brittany R Eberl, Rosemary U Richard, Ena I Campos-Hensley, Adanze N Nnyagu, W Austin Elam, Ai-Ni Tsao, Jack R Tremblay, Ruiying Ma, Alfred K Dei-Ampeh, Kieu Pham, Daniel C Kraushaar, Kwanha Yu, Calla M Olson, Akdes Serin-Harmanci, Benjamin Deneen, Jamie N Anastas

Aberrant neurotransmitter signaling and transcriptional dysregulation are hallmarks of gliomagenesis and represent potential therapeutic targets. Monoamine neurotransmitters such as dopamine and serotonin primarily activate GPCRs but can also function epigenetically as histone H3 modifications. Here, we uncover mechanisms of crosstalk between monoamine neurotransmitter signaling, H3 dopaminylation, and RNA polymerase II (Pol2) transcription in diffuse midline glioma (DMG). We find that co-treatment with Pol2-targeting CDK9 inhibitors (CDK9i) and FDA-approved neuropsychiatric drugs, including selective serotonin reuptake inhibitors (SSRIs), synergistically reduces DMG growth. Mechanistically, CDK9i+SSRI treatment alters H3 dopaminylation patterns and represses synaptic and neurodevelopmental gene transcription associated with CDK9i resistance. Further phospho-proteomic …

Viral infection polarizes monocyte-derived dendritic cells (moDC) to initiate type 1 immunity. The availability of overlapping (homologous) MHC class I and II epitopes, an occurrence frequently and primarily associated with intracellular infection, significantly enhances this process; however, the underlying mechanism(s) are unclear. We demonstrate that moDC loaded with homologous MHC epitopes acquire a cDC1-like phenotype in a process governed by mTORC1. mTORC1 pathway inhibition leads to NF-κB-mediated expression of IL-12 and other type I immune polarizing genes. The observed cDC1-like gene signature was also significantly enhanced in clinical moDC vaccine products made through methodologies that enforced class I and II …

Structure-Preserving Multivariate Hypothesis Testing For Mass Spectrometry Imaging And Single-Cell Data, Keziah E Liebenberg, Erin Craig, Robert Tibshirani, Livia S Eberlin

Faculty, Staff and Students Publications

Motivation: Mass spectrometry imaging (MSI) and single-cell RNA sequencing (scRNA-seq) offer high-resolution views into tissue and cellular heterogeneity. However, conventional statistical analyses often treat sub-measurements (pixels or cells) as independent, ignoring their nested origin from individual samples. This assumption inflates the effective sample size, increases false discoveries, and undermines biological interpretation. Pixel- or cell-level averaging avoids this but sacrifices spatial or cellular resolution.

Results: We evaluated block-SAM on both simulated and real-world datasets. In DESI-MSI data from kidney, lung, and ovarian tumors, block-SAM consistently identified fewer-but more reliable-differential features compared to traditional-SAM. For example, in the kidney dataset, traditional-SAM identified …
