Background and Objectives

While somatic mutations have been well-studied in cancer, their roles in other complex traits are much less understood. Our goal is to identify somatic variants that may contribute to the formation of saccular cerebral aneurysms.

Methods

We performed whole-exome sequencing on aneurysm tissues and paired peripheral blood. RNA sequencing and the CRISPR/Cas9 system were then used to perform functional validation of our results.

Results

Somatic variants involved in supervillin (SVIL) or its regulation were found in 17% of aneurysm tissues. In the presence of a mutation in the SVIL gene, the expression level of SVIL …

Uncloaking Cell-Impermeant Gold Nanorods Via Tumor Microenvironmental Cathepsin B Facilitates Cancer Cell Penetration And Potent Radiosensitization, Valeria Gonzalez, Paul Derry, Eugene Zubarev, Onur Sahin, Joseph Byung-Kyu Kim, Pankaj K Singh, Sang Hyun Cho, Sunil Krishnan

Faculty, Staff and Student Publications

Major impediments to conveyance of intravenously administered drugs to tumors are biofouling, opsonization, and rapid clearance from the circulation by macrophages and reticuloendothelial phagocytes. Cloaking nanoparticles with stealth epilayers partly overcomes these hurdles but it also foils interactions with tumor cells. Here, we describe the synthesis, characterization, and validation of smart gold nanorods (GNRs) that spontaneously transform from inert passengers in the blood stream to active cell-penetrating nanoparticles within tumors to potently sensitize tumors to radiation therapy. Intrinsically cationic and cell-penetrating GNRs were shielded from phagocytosis with a cloaking polyethylene glycol epilayer containing an intervening cleavable peptide. In the absence …

Background

In vivo studies demonstrate that curcumin increases radioresponse of colorectal cancers. To demonstrate efficacy in humans, we performed a randomized double-blind study of locally advanced rectal cancer (LARC) patients receiving pre-operative chemoradiation therapy (CRT) ± curcumin. We used pathologic complete response (pCR) rate as a surrogate for clinical outcome.

Methods

From 2008–2010, LARC patients were randomized to placebo/curcumin in a 1:2 ratio. Patients received CRT [50.4 gray in 28 fractions; capecitabine (825 mg/m² twice daily)] followed by surgery. Curcumin (4 grams orally, twice daily) or placebo was given throughout CRT and 6 weeks afterward. Toxicity was monitored weekly. …

It’S Not Arthritis! Resolution Of The Illusion Of Joint Space Narrowing With Acetabuloplasty And Labral Reconstruction For The Calcified Labrum, Andrew E Jimenez

Faculty, Staff and Student Publications

Labral calcification may be part of the natural history of untreated femoroacetabular impingement syndrome (FAIS) in certain patients, making it a potential target for intervention with the goal of preserving the hip joint. The purpose of this study was to investigate if calcified labra create the appearance of lateral joint space narrowing and report minimum 2-year patient-reported outcome measures (PROMs) after treating patients with arthroscopic acetabuloplasty and labral reconstruction. Prospectively collected data on patients who underwent primary hip arthroscopy for FAIS and labral tearing from February 2015 to April 2021 were reviewed. Patients treated with primary labral reconstruction for an …

Faculty, Staff and Student Publications

BACKGROUND: Cardiovascular magnetic resonance (CMR) offers comprehensive right ventricular (RV) evaluation in pulmonary arterial hypertension (PAH). Emerging four-dimensional (4D) flow CMR allows visualization and quantification of intracardiac flow components and calculation of phasic blood kinetic energy (KE) parameters but it is unknown whether these parameters are associated with cardiopulmonary exercise test (CPET)-assessed exercise capacity, which is a surrogate measure of survival in PAH. We compared 4D flow CMR parameters in PAH with healthy controls, and investigated the association of these parameters with RV remodelling, RV functional and CPET outcomes.

METHODS: PAH patients and healthy controls from two centers were prospectively …

Endovascular Repair Of Aortic Arch Graft Pseudoaneurysm Using A Duct Occluder Device With Onlay Fusion Guidance, Thanila A Macedo

Faculty, Staff and Student Publications

Aortic arch pseudoaneurysms can be caused by previous surgery, infection, or trauma. In select patients with small tears and no evidence of infection, local repair can be performed using an open or endovascular technique.1 Open surgical repeat surgery has increased risks and endovascular repair has been especially appealing for the elderly, higher risk patients, and patients with multiple prior procedures.2 We have reported the use of a ductal occluder device in a patient with a large aortic arch pseudoaneurysm.3 Our patient has provided written informed consent for the report of his case details and imaging studies.

Healthcare providers who use controlling or coercive strategies may compel short-term enactment of HIV and sexually transmitted infection prevention behaviors but may inadvertently undermine their client's motivation to maintain those behaviors in the absence of external pressure. Autonomous motivation refers to the self-emanating and self-determined drive for engaging in health behaviors. It is associated with long-term maintenance of health behaviors. We used structural equation modeling to investigate whether autonomy support was associated with increased odds of therapeutic serum levels of pre-exposure prophylaxis, through a pathway that satisfies basic psychological needs for autonomous self-regulation and competence regarding pre-exposure prophylaxis use. We …

Unilateral ‘Crazy-Paving’ Pattern: An Exceptional Presentation Of Squamous Cell Carcinoma Of The Lung, Ashok Shah

Faculty, Staff and Student Publications

The 'crazy-paving' pattern on high resolution computed tomography (HRCT) is a distinct imaging appearance that is still considered to be a radiological hallmark of pulmonary alveolar proteinosis. However, since its first description about three decades ago, more than 40 different clinical entities presenting as 'crazy-paving' patterns have been documented. This rather remarkable but uncommon imaging appearance is now considered to be a non-specific manifestation. A 62-year-old male referred for evaluation of productive cough, breathlessness and fever presented with 'crazy-paving' pattern on HRCT. Endobronchial biopsy done on presentation was consistent with the diagnosis of squamous cell carcinoma. This report highlights this …

The Circadian Nobiletin-Ror Axis Suppresses Adipogenic Differentiation And Iκbα/Nf-Κb Signaling In Adipocytes, Chorong Han, Celia K Tran, Zheng Chen, Karyn A Esser, Seung-Hee Yoo

Faculty, Staff and Student Publications

Numerous molecular and physiological processes in the skeletal muscle undergo circadian time-dependent oscillations in accordance with daily activity/rest cycles. The circadian regulatory mechanisms underlying these cyclic processes, especially at the post-transcriptional level, are not well defined. Previously, we reported that the circadian E3 ligase FBXL21 mediates rhythmic degradation of the sarcomere protein TCAP in conjunction with GSK-3β, and Psttm mice harboring an Fbxl21 hypomorph allele show reduced muscle fiber diameter and impaired muscle function. To further elucidate the regulatory function of FBXL21 in skeletal muscle, we investigated another sarcomere protein, Myozenin1 (MYOZ1), that we identified as an FBXL21-binding protein from …

Spontaneous Coronary Artery Dissection Is Infrequent In Individuals With Heritable Thoracic Aortic Disease Despite Partially Shared Genetic Susceptibility, Arash Keyhani

Faculty, Staff and Student Publications

Spontaneous isolated celiac artery dissection (SICAD) is a rare condition, defined as dissection of the celiac artery without aortic involvement. Because of its low prevalence, most studies have been limited to case reports and case series. We have described the case of a 44-year-old woman who had presented with symptomatic SICAD that had resulted in compromised flow to the hepatic arteries and was successfully treated with balloon angioplasty. Angioplasty alone might be effective for cases of extensive false lumen thrombosis in SICAD for immediate flow restoration to the true lumen, expediting positive remodeling.

Targeted Ablation Of Fn14 Receptor Improves Exercise Capacity And Inhibits Neurogenic Muscle Atrophy, Meiricris Tomaz Da Silva, Aniket S Joshi, Tatiana E Koike, Anirban Roy, Kavya Mathukumalli, Vihang A Narkar

Faculty, Staff and Student Publications

Skeletal muscle atrophy is a prevalent complication in multiple chronic diseases and disuse conditions. Fibroblast growth factor-inducible 14 (Fn14) is a member of the TNF receptor superfamily and a bona fide receptor of the TWEAK cytokine. Accumulating evidence suggests that Fn14 levels are increased in catabolic conditions as well as during exercise. However, the role of Fn14 in the regulation of skeletal muscle mass and function remains poorly understood. In this study, through the generation of novel skeletal muscle-specific Fn14-knockout mice, we have investigated the muscle role of Fn14 in the regulation of exercise capacity and denervation-induced muscle atrophy. Our …

Remodeling Of The Plasma Membrane By Surface-Bound Protein Monomers And Oligomers: The Critical Role Of Intrinsically Disordered Regions

Faculty, Staff and Student Publications

The plasma membrane (PM) of cells is a dynamic structure whose morphology and composition is in constant flux. PM morphologic changes are particularly relevant for the assembly and disassembly of signaling platforms involving surface-bound signaling proteins, as well as for many other mechanochemical processes that occur at the PM surface. Surface-bound membrane proteins (SBMP) require efficient association with the PM for their function, which is often achieved by the coordinated interactions of intrinsically disordered regions (IDRs) and globular domains with membrane lipids. This review focuses on the role of IDR-containing SBMPs in remodeling the composition and curvature of the PM. …

A Substring Replacement Approach For Identifying Missing Is-A Relations In Snomed Ct

Faculty, Staff and Student Publications

Biomedical ontologies provide formalized information and knowledge in the biomedical domain. Over the years, biomedical ontologies have played an important role in facilitating biomedical research and applications. Common quality issues of biomedical ontologies include inconsistent naming of concepts, redundant concepts, redundant relations, incomplete/incorrect concept definitions, and incomplete/incorrect class hierarchies. In this work, we focus on addressing the incompleteness of the class hierarchy in SNOMED CT. We develop a substring replacement approach, leveraging concepts’ lexical features and existing IS-A relations to identify potential missing IS-A relations in SNOMED CT. To evaluate the effectiveness of our approach, we performed both automated and …
