The Impact Of Diabetes On Neurovascular Integrity: A Special Focus On Pericytes And Endothelin-1, Mia Edgerton

MUSC Theses and Dissertations

Diabetes increases the risk of stroke and Vascular Contributions to Cognitive Impairment and Dementia (VCID). Diabetes also dysregulates the endothelin (ET) system. ET-1-mediated constriction of brain microvascular pericytes (BMVPCs) has been shown to contribute to brain hypoperfusion. However, there is a loss of BMVPCs in VCID, but underlying mechanisms of pericyte degeneration are poorly studied. ETA receptor activation can instigate phenotypical changes and cellular senescence in endothelial cells. . There is also emerging evidence that ETB receptor agonism improves outcomes in patients with cerebral ischemic stroke, but long-term effects, especially in diabetes, are unknown. Therefore, this study aimed to determine …

Physics & Astronomy Faculty Publications

This study investigates the use of chitosan, extracted from pink shrimp shells, as a stabilizer for argan oil nanoemulsions. Chitosan was obtained through demineralization, deproteination, bleaching, deacetylation, and purification, then characterized through potentiometric titration, viscometry, X-ray diffraction (XRD), scanning electron microscopy (SEM), and purity assessments. The resulting chitosan was used to stabilize nanoemulsions formulated with extra-virgin argan oil and a nonionic surfactant using the phase inversion composition (PIC) method. The stability of the nanoemulsion was assessed through light scattering, zeta potential, viscosity, and pH measurements. The extracted chitosan exhibited high purity, a deacetylation degree of 88.34%, a molecular weight of …

Refractory Dermatitis Evolving Into Lupus Spectrum Disease In The Setting Of Dupilumab Use, Jonathan M. Joseph, Jacob Kilgore, Nicholas Culotta

School of Medicine Faculty Publications

Cutaneous lupus erythematosus (CLE) encompasses a broad range of clinical and histopathologic variants that can overlap with other dermatologic entities, complicating accurate diagnosis. We report the case of a 42-year-old male patient who initially presented with a diffuse pruritic eruption presumed to be atopic dermatitis, for which dupilumab was initiated. Within the following weeks, the patient developed a fever of unknown origin and diarrhea, raising concern for an atypical drug-related reaction or an unmasked autoimmune process. Subsequent biopsies demonstrated evolving histopathologic features, including superficial and deep perivascular dermatitis suggestive of drug eruption. In addition, a dermal mucin deposition with mixed …

Novel Device Therapies In Heart Failure: Focus On Patient Selection, Amrita Balgobind, Daniel Asemota, Emily Rodriguez, Phuuwadith Wattanachayakul, Marat Fudim, Miguel Alvarez Villela

Einstein Health Papers

The increasing prevalence of heart failure (HF) has led to advancements in therapeutic strategies, including the development of new pharmacological treatments and the expansion of guideline recommendations across the spectrum of left ventricular ejection fractions. Despite these advancements, the full benefits of guideline-directed medical therapy (GDMT) are often limited by various barriers that result in incomplete implementation or suboptimal responses. For patients who cannot tolerate or only partially respond to GDMT, therapeutic options remain limited. This gap is particularly significant for those with contraindications to heart replacement therapies (HRT), such as left ventricular assist device (LVAD) or heart transplant. In …

Advances In Immunotherapy In Hepatocellular Carcinoma, Matthew D. Bloom, Sourav Podder, Hien Dang, Daniel Lin

Department of Medical Oncology Faculty Papers

Over the past several years, the therapeutic landscape for patients with advanced, unresectable, or metastatic hepatocellular carcinoma has been transformed by the incorporation of checkpoint inhibitor immunotherapy into the treatment paradigm. Frontline systemic treatment options have expanded beyond anti-angiogenic tyrosine kinase inhibitors, such as sorafenib, to a combination of immunotherapy approaches, including atezolizumab plus bevacizumab and durvalumab plus tremelimumab, both of which have demonstrated superior response and survival to sorafenib. Additionally, combination treatments with checkpoint inhibitors and tyrosine kinase inhibitors have been investigated with variable success. In this review, we discuss these advances in systemic treatment with immunotherapy, with a …

Openmmdl - Simplifying The Complex: Building, Simulating, And Analyzing Protein-Ligand Systems In Openmm, Valerij Talagayev, Yu Chen, Niklas Piet Doering, Leon Obendorf, Katrin Denzinger, Kristina Puls, Kevin Lam, Sijie Liu, Clemens Alexander Wolf, Theresa Noonan, Marko Breznik, Petra Knaus, Gerhard Wolber

Faculty, Staff and Student Publications

Molecular dynamics (MD) simulations have become an essential tool for studying the dynamics of biological systems and exploring protein–ligand interactions. OpenMM is a modern, open-source software toolkit designed for MD simulations. Until now, it has lacked a module dedicated to building receptor–ligand systems, which is highly useful for investigating protein–ligand interactions for drug discovery. We therefore introduce OpenMMDL, an open-source toolkit that enables the preparation and simulation of protein–ligand complexes in OpenMM, along with the subsequent analysis of protein–ligand interactions. OpenMMDL consists of three main components: OpenMMDL Setup, a graphical user interface based on Python Flask to …

Leukapheresis is a potentially life-saving therapy for children with symptomatic hyperleukocytosis. However, the standard centrifugation-based approach exposes pediatric patients to significant complications due to its large extracorporeal volume, high flow rates, and considerable platelet loss. Here, we tested whether performing cell separation with a high-throughput microfluidic technology could alleviate these limitations. In vitro, our microfluidic devices removed ~85% of large leukocytes and ~90% of spiked leukemic blasts from undiluted human whole blood, while minimizing platelet losses. Multiplexed devices connected in parallel allowed for faster, clinically relevant flow rates in vitro with no difference in leukocyte collection efficiency. When connected to …

2020-Current year OA Pubs

BACKGROUND: Local public health departments in the United States are responsible for implementing cancer-related programs and policies in their communities; however, many staff have not been trained to use evidence-based processes, and the organizational climate may be unsupportive of evidence-based processes. A promising approach to address these gaps is through academic-public health department (AHD) partnerships, in which practitioners and academics collaborate to improve public health practice and education through joint research projects and educational opportunities. Prior research has demonstrated the benefits of AHD partnerships to public health practice and education. However, knowledge about how AHD partnerships should be structured to …

Meeting Micronutrient Needs Of Children Aged Six Months To Five Years, Stephanie Enjaian

Master of Nutrition and Dietetics

Ensuring nutritional adequacy and developing positive dietary behaviors during early childhood is critical for establishing lifelong healthy habits (Hasnin, Dev, & Tovar, 2020). Children aged six months to five years rely exclusively on their caregivers for their dietary needs and food environment. Micronutrient needs for children aged six months to five years greatly vary as children grow rapidly during this stage of life. Children begin learning self-feeding by the age of one and establish meal patterns (Mahmood, Flores-Barrantes, Moreno, Manios, & Gonzalez-Gil, 2021).

Primary sources of energy and micronutrients dramatically shift from milk at one to two years to solid …

Memorability Of Novel Words Correlates With Anterior Fusiform Activity During Reading, Oscar Woolnough, Nitin Tandon

Faculty, Staff and Student Publications

Our memory for the words we already know is best predicted by their associated meanings. However, the factors that influence whether we will remember a new word after we see it for the first time are unclear. We record memory performance for 2100 novel pseudowords across 1804 participants during a continuous recognition task. Participants show significant agreement across individuals for which novel words were memorable or forgettable, suggesting an intrinsic memorability for individual pseudowords. Pseudowords that are similar to low-frequency known words, with sparse orthographic neighbourhoods and rarely occurring letter pairs, are more memorable. Further, using intracranial recordings in 36 …

The Dementia Care Partner Hub: An Innovative Approach To Addressing Unmet Social And Health Needs, Sherril Gelmon, Jenn Reed, Walter D. Dawson

OHSU-PSU School of Public Health Faculty Publications and Presentations

The well‐being of care partners of people living with dementia, who are family, friends, or neighbors and often unpaid, is often not addressed explicitly in clinical dementia care. Care partners, especially those from systematically marginalized communities, experience substantial unmet social and behavioral needs. We reviewed role model programs and conducted focus groups and interviews with care partners and representatives of community organizations and government agencies. We developed the concept of a Dementia Care Partner Hub as a “one‐stop shop” to connect dementia care partners and service providers with information and resources, meeting a need that is not currently addressed in …

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Chronic lymphocytic leukemia (CLL) is the most common type of adult leukemia, particularly in Western countries. CLL can present indolently or aggressively, influenced by various factors, including chromosomal alterations. Fluorescent in situ hybridization (FISH), targeting specific genes/loci frequently affected in CLL patients, has established a standard for stratifying five CLL prognostic groups: del(11q)/ATM, trisomy 12, del(13q) as a sole aberration, del(17p)/TP53, and normal CLL FISH panel results. Among these, del(13q) as a sole aberration is associated with a favorable prognosis, while the others are considered intermediate (normal CLL FISH panel result and trisomy 12) or unfavorable (del(11q)/ATM and del(17p)/TP53) prognostic …

School of Medicine Publications

Background

Type 2 diabetes (T2D) etiology is highly complex due to its multiple roots of origin. Polygenic risk scores (PRS) based on genome-wide association studies (GWAS) can partially explain T2D risk. Asian Indian people have up to six times higher risk of developing T2D than European people, and underlying causes of this disparity are unknown.

Methods

We have performed targeted sequencing of ten T2D GWAS/candidate regions using endogamous Punjabi Sikh families and replication studies using unrelated Sikh people and families from three other Indian endogamous ethnic groups (EEGs).

Results

We detect rare and ultra-rare variants (RVs) in KCNJ11-ABCC8 …

Routine Evaluation Of Supracondylar Humerus Fracture Percutaneous Pin Sites Does Not Decrease Complications: A Retrospective Comparative Cohort, Alexis Aboulafia, Brendan Grant, Rohini M Vanodia, Lindsay M Crawford, Shiraz A Younas, Alfred A Mansour

Faculty, Staff and Student Publications

Background: Supracondylar humerus (SCH) fractures are the most common type of pediatric elbow fractures that require surgical intervention. Studies suggest limiting the first postoperative visit to the time of pin removal or limiting radiographs at first postoperative follow-up may not increase complication rates, but few comparative studies exist. This study aims to determine if routinely examining surgical pins sites at the first postoperative visits affects the complication rates or outcomes compared to only evaluating pin sites if a clinical indication exists.

Methods: This cohort study retrospectively reviewed patients who were surgically treated for a supracondylar humerus fracture at a Pediatric …
