BACKGROUND AND OBJECTIVES: Functional outcomes after stroke are strongly related to focal injury measures. However, the role of global brain health is less clear. In this study, we examined the impact of brain age, a measure of neurobiological aging derived from whole-brain structural neuroimaging, on poststroke outcomes, with a focus on sensorimotor performance. We hypothesized that more lesion damage would result in older brain age, which would in turn be associated with poorer outcomes. Related, we expected that brain age would mediate the relationship between lesion damage and outcomes. Finally, we hypothesized that structural brain resilience, which we define in …

Zinc Treatment Reverses And Anti-Zn-Regulated Mirs Suppress Esophageal Carcinomas In Vivo, Louise Fong, Kay Huebner, Ruiyan Jing, Karl Smalley, Christopher R Brydges, Oliver Fiehn, John Farber, Carlo M Croce

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Esophageal squamous cell carcinoma (ESCC) is a deadly disease with few prevention or treatment options. ESCC development in humans and rodents is associated with Zn deficiency (ZD), inflammation, and overexpression of oncogenic microRNAs: miR-31 and miR-21. In a ZD-promoted ESCC rat model with upregulation of these miRs, systemic antimiR-31 suppresses the miR-31-EGLN3/STK40-NF-κB-controlled inflammatory pathway and ESCC. In this model, systemic delivery of Zn-regulated antimiR-31, followed by antimiR-21, restored expression of tumor-suppressor proteins targeted by these specific miRs: STK40/EGLN3 (miR-31), PDCD4 (miR-21), suppressing inflammation, promoting apoptosis, and inhibiting ESCC development. Moreover, ESCC-bearing Zn-deficient (ZD) rats receiving Zn medication showed a 47% …

Apolipoprotein E Dyslipidemia And Nephrotic Syndrome: A Rare Connection, Sahana Tito, Avica Atri, Shivaraj Patil, Saima Dean, Sweta Carpenter

Einstein Health Papers

Severe hyperlipidemia warrants an extensive evaluation. We report a case of a 25-year-old man of Chinese descent seen in the cardiology-lipid clinic. He was found to have a serum low-density lipoprotein cholesterol of 12.12 mmol/L (468 mg/dL) and serum triglycerides of 2.29 mmol/L (203 mg/dL) during routine screening. Work-up revealed nephrotic-range proteinuria, and renal biopsy showed dilated glomerular capillary loops with lipid deposits, pathognomonic of lipoprotein glomerulopathy. Genetic studies showed apolipoprotein E3/E4 phenotype. He was treated with a high-intensity statin and fibrate therapy, which resulted in a marked improvement in dyslipidemia and proteinuria.

Telehealth Clinical Appropriateness And Quality, Lulu Wang, Anthony Fabiano, Arjun K. Venkatesh, Nick Patel, Judd E. Hollander

Department of Emergency Medicine Faculty Papers

Contrary to common perception, telehealth is not simply a substitute for in-person care. With an array of modalities—live audio–video, asynchronous patient communication, and remote patient monitoring, to name a few—telehealth creates entirely new avenues of care delivery (Table 1). Although our current care model is reactive—relying on episodic visits to an office or hospital—telehealth allows us to be proactive, filling in the gaps to provide a continuum of care. Widespread uptake of telehealth has created fertile ground for long-overdue health system reform. In this study, we describe essential next steps: redefine telehealth clinical appropriateness, evolve payment models, provide necessary training, …

A Computationally Designed Ace2 Decoy Has Broad Efficacy Against Sars-Cov-2 Omicron Variants And Related Viruses In Vitro And In Vivo, Brandon Havranek, Graeme Walker Lindsey, Yusuke Higuchi, Yumi Itoh, Tatsuya Suzuki, Toru Okamoto, Atsushi Hoshino, Erik Procko, Shahidul M. Islam

SKMC Student Presentations and Publications

SARS-CoV-2, especially B.1.1.529/omicron and its sublineages, continues to mutate to evade monoclonal antibodies and antibodies elicited by vaccination. Affinity-enhanced soluble ACE2 (sACE2) is an alternative strategy that works by binding the SARS-CoV-2 S protein, acting as a 'decoy' to block the interaction between the S and human ACE2. Using a computational design strategy, we designed an affinity-enhanced ACE2 decoy, FLIF, that exhibited tight binding to SARS-CoV-2 delta and omicron variants. Our computationally calculated absolute binding free energies (ABFE) between sACE2:SARS-CoV-2 S proteins and their variants showed excellent agreement to binding experiments. FLIF displayed robust therapeutic utility against a broad range …

Ghilardi, John-Ross Rizzo

Department of Exercise Science Faculty Papers

Introduction: Parkinson’s disease (PD) is the second most prevalent neurodegenerative disease. Complementary and alternative therapies are increasingly utilized to address its complex multisystem symptomatology. Art therapy involves motoric action and visuospatial processing while promoting broad biopsychosocial wellness. The process involves hedonic absorption, which provides an escape from otherwise persistent and cumulative PD symptoms, refreshing internal resources. It involves the expression in nonverbal form of multilayered psychological and somatic phenomena; once these are externalized in a symbolic arts medium, they can be explored, understood, integrated, and reorganized through verbal dialogue, effecting relief and positive change.

Methods: 42 participants with mild to …

Dynamic Role Of Exosome Micrornas In Cancer Cell Signaling And Their Emerging Role As Noninvasive Biomarkers, Jaya Aseervatham

Department of Neurology Faculty Papers

Exosomes are extracellular vesicles that originate from endosomes and are released by all cells irrespective of their origin or type. They play an important role in cell communication and can act in an autocrine, endocrine, or paracrine fashion. They are 40–150 nm in diameter and have a similar composition to the cell of origin. An exosome released by a particular cell is unique since it carries information about the state of the cell in pathological conditions such as cancer. miRNAs carried by cancer-derived exosomes play a multifaceted role by taking part in cell proliferation, invasion, metastasis, epithelial–mesenchymal transition, angiogenesis, apoptosis, …

A Conditional Strategy For Cell-Type-Specific Labeling Of Endogenous Excitatory Synapses In Drosophila, Michael J. Parisi, Michael A. Aimino, Timothy J. Mosca

Farber Institute for Neuroscience Faculty Papers

Chemical neurotransmission occurs at specialized contacts where neurotransmitter release machinery apposes neurotransmitter receptors to underlie circuit function. A series of complex events underlies preand postsynaptic protein recruitment to neuronal connections. To better study synaptic development in individual neurons, we need cell-type-specific strategies to visualize endogenous synaptic proteins. Although presynaptic strategies exist, postsynaptic proteins remain less studied because of a paucity of cell-type-specific reagents. To study excitatory postsynapses with cell-type specificity, we engineered dlg1[4K], a conditionally labeled marker of Drosophila excitatory postsynaptic densities. With binary expression systems, dlg1[4K] labels central and peripheral postsynapses in larvae and adults. Using dlg1[4K], we find …

Contributions To Auditory System Conduction Velocity: Insights With Multi-Modal Neuroimaging And Machine Learning In Children With Asd And Xyy Syndrome, Jeffrey I. Berman, Luke Bloy, Lisa Blaskey, Carissa R. Jackel, Judith S. Miller, Judith Ross, J. Christopher Edgar, Thimothy P.L. Roberts

Department of Pediatrics Faculty Papers

Introduction: The M50 electrophysiological auditory evoked response time can be measured at the superior temporal gyrus with magnetoencephalography (MEG) and its latency is related to the conduction velocity of auditory input passing from ear to auditory cortex. In children with autism spectrum disorder (ASD) and certain genetic disorders such as XYY syndrome, the auditory M50 latency has been observed to be elongated (slowed).

Methods: The goal of this study is to use neuroimaging (diffusion MR and GABA MRS) measures to predict auditory conduction velocity in typically developing (TD) children and children with autism ASD and XYY syndrome.

Results: Non-linear TD …

South, Marcelo Ezquer, Ignacia Fuentes

Department of Dermatology and Cutaneous Biology Faculty Papers

BACKGROUND: Recessive Dystrophic Epidermolysis Bullosa (RDEB) is a rare inherited skin disease caused by variants in the COL7A1 gene, coding for type VII collagen (C7), an important component of anchoring fibrils in the basement membrane of the epidermis. RDEB patients suffer from skin fragility starting with blister formation and evolving into chronic wounds, inflammation and skin fibrosis, with a high risk of developing aggressive skin carcinomas. Restricted therapeutic options are limited by the lack of in vitro models of defective wound healing in RDEB patients.

RESULTS: In order to explore a more efficient, non-invasive in vitro model for RDEB studies, …

Springer, Jihae Choi, Christopher M. Snyder, Yajing Wang, Sangwon V. Kim, Luis J. Sigal

Department of Microbiology and Immunology Faculty Papers

Genetically modified (GM) mice are essential tools in biomedical research. Traditional methods for generating GM mice are expensive and require specialized personnel and equipment. The use of clustered regularly interspaced short palindromic repeats (CRISPR) coupled with improved-Genome editing via Oviductal Nucleic Acids Delivery (i-GONAD) has highly increased the feasibility of producing GM mice in research laboratories. However, genetic modification in inbred mouse strains of interest such as C57BL/6 (B6) is still challenging because of their low fertility and embryo fragility. We have successfully generated multiple novel GM mouse strains in the B6 background while attempting to optimize i-GONAD. We found …

Abington Jefferson Health Papers

Myopericarditis associated with COVID-19 mRNA vaccines has been recognized as an uncommon adverse reaction, especially among young, healthy adult males. Eosinophilic myocarditis is a rare form of inflammation reflecting a hypersensitivity reaction following an inciting event commonly caused by drugs including vaccines. Eosinophilic myocarditis, a subtype of myocarditis, is characterized by eosinophilic myocardial infiltrates. It is usually accompanied by systemic eosinophilia in the form of a drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome and is rarely associated with myocyte fibrosis and/or necrosis. In this report, we present a case of biopsy-proven eosinophilic myocarditis in a 24-year-old male patient, …

Department of Medicine Faculty Papers

Progression of disease within 24 months (POD24) from diagnosis in marginal zone lymphoma (MZL) was shown to portend poor outcomes in prior studies. However, many patients with MZL do not require immediate therapy, and the time from diagnosis-to-treatment interval can be highly variable with no universal criteria to initiate systemic therapy. Hence, we sought to evaluate the prognostic relevance of early relapse or progression within 24 months from systemic therapy initiation in a large US cohort. The primary objective was to evaluate the overall survival (OS) in the two groups. The secondary objective included the evaluation of factors predictive of …

Division of Cardiology Faculty Papers

Background

Effective control of risk factors in patients with ASCVD is important to reduce recurrent cardiovascular events. However, many ASCVD patients do not have their risk factors controlled, and this may have worsened during the COVID-19 pandemic.

Methods

We retrospectively evaluated risk factor control among 24,760 ASCVD patients who had at least 1 outpatient encounter both pre-pandemic and during the first year of the pandemic. Risk factors were uncontrolled if the blood pressure (BP) ≥ 130/80 mm Hg, LDL-C ≥ 70 mg/dL, HgbA1c ≥ 7 for diabetic patients, and patients were current smokers.

Results

During the pandemic, many patients had …

Marcus Institute of Integrative Health Faculty Papers

The Supreme Court decision in Dobbs v. Jackson in June 2022 reversed precedent which had previously protected abortion prior to fetal viability as a universal right within the United States. This decision almost immediately led to abortion restrictions across 25 states. The resulting lack of access to abortion care for millions of pregnant people will have profound physical and mental health consequences, the full effects of which will not be realized for years to come. Approximately 1 in 5 women access abortions in the U.S. each year. These women are diverse and represent all American groups. The Supreme court decision, …

Species Differences In Platelet Protease-Activated Receptors, Stephanie A Renna, Steven E. Mckenzie, James V. Michael

Cardeza Foundation for Hematologic Research

Protease-activated receptors (PARs) are a class of integral membrane proteins that are cleaved by a variety of proteases, most notably thrombin, to reveal a tethered ligand and promote activation. PARs are critical mediators of platelet function in hemostasis and thrombosis, and therefore are attractive targets for anti-platelet therapies. Animal models studying platelet PAR physiology have relied heavily on genetically modified mouse strains, which have provided ample insight but have some inherent limitations. The current review aims to summarize the notable PAR expression and functional differences between the mouse and human, in addition to highlighting some recently developed tools to further …

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Calcium transfer into the mitochondrial matrix during sarcoplasmic reticulum (SR) Ca²⁺ release is essential to boost energy production in ventricular cardiomyocytes (VCMs) and match increased metabolic demand. Mitochondria from female hearts exhibit lower mito-[Ca²⁺] and produce less reactive oxygen species (ROS) compared to males, without change in respiration capacity. We hypothesized that in female VCMs, more efficient electron transport chain (ETC) organization into supercomplexes offsets the deficit in mito-Ca²⁺ accumulation, thereby reducing ROS production and stress-induced intracellular Ca²⁺ mishandling. Experiments using mitochondria-targeted biosensors confirmed lower mito-ROS and mito-[Ca²⁺] in female rat VCMs challenged …
