Medical Student Research Symposium
Mindfulness based interventions (MBI) reduce the severity of anxiety and depression among a variety of populations. While the psychological benefits of MBIs are increasingly recognized, less is known about the underlying neural correlates—particularly during childhood and adolescence, a time when many psychopathologies begin to emerge. Here, we provide the first systematic review on the neural correlates of MBI in youth. We reviewed the PubMed database for original articles examining the neural correlates of MBI in youth (0-18 years) leveraging neuroimaging. The search yielded 331 studies, of which 13 were included in the review. These studies comprised 451 participants and were …

BACKGROUND: Nur77 belongs to the member of orphan nuclear receptor 4A family that plays critical roles in maintaining vascular homeostasis. This study aims to determine whether Nur77 plays a role in attenuating vascular dysfunction, and if so, to determine the molecular mechanisms involved.
METHODS: Both Nur77 knockout (Nur77 KO) and Nur77 endothelial specific transgenic mice (Nur77-Tg) were employed to examine the functional significance of Nur77 in vascular endothelium in vivo. Endothelium-dependent vasodilatation to acetylcholine (Ach) and reactive oxygen species (ROS) production was determined under inflammatory and high glucose conditions. Expression of genes was determined by real-time PCR and western blot …

Pkcε Activator Protects Hippocampal Microvascular Disruption And Memory Defect In 3×Tg-Alzheimer's Disease Mice With Cerebral Microinfarcts, Huaixing Wang, Zongxiu Zhang, Jarin Hongpaisan
Center for Translational Medicine Faculty Papers
BACKGROUND: Current evidence suggests that microvessel disease is involved in Alzheimer's disease (AD). Cerebrovascular disease correlates with cardiovascular disease and is complicated in ≈40% of AD patients. The protein kinase C (PKC) ε activator DCPLA can stimulate human antigen (Hu) R that prevents degradation and promotes the translation of mitochondrial Mn-superoxide dismutase (MnSOD) and vascular endothelial growth factor-A (VEGF) mRNAs.
METHODS: To induce brain microinfarcts, we injected triple transgenic (3×Tg) and wild-type (WT) control mice with microbeads (20 μm caliber) into common carotid arteries, with or without the DCPLA-ME (methyl-ester) for 2 weeks. After water maze training, mice at 16 …

Asthma is a chronic inflammatory airway disease characterized by airway hyperresponsiveness (AHR), inflammation, and goblet cell hyperplasia. Multiple cytokines, including IFNγ, IL-4, and IL-13 are associated with asthma; however, the mechanisms underlying the effects of these cytokines remain unclear. Here, we report a significant increase in the expression of IL-31RA, but not its cognate ligand IL-31, in mouse models of allergic asthma. In support of this, IFNγ, IL-4, and IL-13 upregulated IL-31RA but not IL-31 in both human and mice primary airway smooth muscle cells (ASMC) isolated from the airways of murine and human lungs. Importantly, the loss of IL-31RA …

A dominant mutation in hnRNPA1 causes amyotrophic lateral sclerosis (ALS), but it is not known whether this mutation leads to motor neuron death through increased or decreased function. To elucidate the relationship between pathogenic hnRNPA1 mutation and its native function, we created novel transgenic rats that overexpressed wildtype rat hnRNPA1 exclusively in motor neurons. This targeted expression of wildtype hnRNPA1 caused severe motor neuron loss and subsequent denervation muscle atrophy in transgenic rats that recapitulated the characteristics of ALS. These findings demonstrate that the augmentation of hnRNPA1 expression suffices to trigger motor neuron degeneration and the manifestation of ALS-like phenotypes. …
Immune Responses Induced At One Hour Post Cataract Surgery Wounding Of The Chick Lens, Jodirae Dedreu, Morgan Basta, Janice Walker, Sue Menko
Immune Responses Induced At One Hour Post Cataract Surgery Wounding Of The Chick Lens, Jodirae Dedreu, Morgan Basta, Janice Walker, Sue Menko
Department of Pathology, Anatomy, and Cell Biology Faculty Papers
While the lens is an avascular tissue with an immune-privileged status, studies have now revealed that there are immune responses specifically linked to the lens. The response to lens injury, such as following cataract surgery, has been shown to involve the activation of the resident immune cell population of the lens and the induction of immunomodulatory factors by the wounded epithelium. However, there has been limited investigation into the immediate response of the lens to wounding, particularly those induced factors that are intrinsic to the lens and its associated resident immune cells. Using an established chick embryo ex vivo cataract …

In this comprehensive review, we will dissect the impact of research on proteoglycans focusing on recent developments involved in their synthesis, degradation, and interactions, while critically assessing their usefulness in various biological processes. The emerging roles of proteoglycans in global infections, specifically the SARS-CoV-2 pandemic, and their rising functions in regenerative medicine and biomaterial science have significantly affected our current view of proteoglycans and related compounds. The roles of proteoglycans in cancer biology and their potential use as a next-generation protein-based adjuvant therapy to combat cancer is also emerging as a constructive and potentially beneficial therapeutic strategy. We will discuss …
Communicating Unexpected Genetic Information With Family Members: A Multimethod Study Of Secondary Findings Recipients, Julie Chevalier Sapp
Communicating Unexpected Genetic Information With Family Members: A Multimethod Study Of Secondary Findings Recipients, Julie Chevalier Sapp
Doctor of Philosophy in Translational Health Sciences Dissertations
Background: Medically-actionable secondary genomic findings (SF) can be life- preserving or life-prolonging for recipients but this benefit can only extend to family members if this information is shared with relatives. How SF recipients communicate this important genetic information with relatives, barriers and facilitators to this process, and SF recipients’ lived experiences in communicating about their results over time remain largely unknown. Family communication is required for relatives of SF recipients to access cascade testing and the potential benefits of enhanced screening and management. Applying behavioral and implementation science theories and providing rich and deep descriptions of SF recipients’ lived experiences …

Virtual Education Implementation For Children With Autism Spectrum Disorders Amidst The Covid-19 Pandemic, Monika Sinha-Bhamra
Doctor of Philosophy in Translational Health Sciences Dissertations
Background: The COVID-19 pandemic led to widespread school closures in the Washington DC metropolitan region, necessitating a shift from traditional in-person education to virtual platforms. The context was significantly influenced by the evolving pandemic and its impact on the region's COVID-19 positive rates, with the Washington DC region facing some of the highest positive rates in 2020. These escalating positive rates posed substantial challenges to planning and implementing in-person learning, primarily driven by concerns for public health and safety. The region's persistently low percentages of in-person learning made it one of the worst in the country regarding the provision of …

In recent years, there has been increased accessibility to cannabis for recreational and medicinal use. Incidentally, there has been an increase in reports describing allergic reactions to cannabis including exacerbation of underlying asthma. Recently, multiple protein allergens were discovered in cannabis, yet these fail to explain allergic sensitization in many patients, particularly urticaria and angioedema. Cannabis has a rich chemical profile including cannabinoids and terpenes that possess immunomodulatory potential. We examined whether major cannabinoids of cannabis such as cannabidiol (CBD) and the bicyclic sesquiterpene beta-caryophyllene (β-CP) act as contact sensitizers. The repeated topical application of mice skin with β-CP at …

Conference Presentation Abstracts
Introduction: Lupus anticoagulants (LA) are antibodies directed against phospholipids/phospholipid-protein complexes involved in coagulation and are associated with thrombotic events and recurrent fetal loss. There is no gold standard test for LA, therefore at least two LA-specific tests are recommended before excluding LA. Potential testing methods involve dilute Russell viper venom time (dRVVT) and hexagonal phase phospholipid assays (HPPA); however, many of these tests are susceptible to interference with anticoagulant therapy which can lead to false positive results. In this study, we compared the performance of our current HPPA, StaClot LA (SCLA), with a novel assay reported to have relatively minimal …

Allergic sensitization to cannabis is an emerging public health concern and is difficult to clinically establish owing to lack of standardized diagnostic approaches. Attempts to develop diagnostic tools were largely hampered by the Schedule I restrictions on cannabis, which limited accessibility for research. Recently, however, hemp was removed from the classified list, and increased accessibility to hemp allows for the evaluation of its practical clinical value for allergy diagnosis. We hypothesized that the proteomic profile is preserved across different cannabis chemotypes and that hemp would be an ideal source of plant material for clinical testing. Using a proteomics-based approach, we …

Abaloparatide Maintains Normal Rat Blood Calcium Level In Part Via 1,25-Dihydroxyvitamin D/Osteocalcin Signaling Pathway, Yanmei Yang, Wei-Ju Louis Tseng, Bin Wang
Center for Translational Medicine Faculty Papers
The PTH-related peptide(1-34) analog, abaloparatide (ABL), is the second anabolic drug available for the treatment of osteoporosis. Previous research demonstrated that ABL had a potent anabolic effect but caused hypercalcemia at a significantly lower rate. However, the mechanism by which ABL maintains the stability of blood calcium levels remains poorly understood. Our in vivo data showed that ABL treatment (40 µg/kg/day for 7 days) significantly increased rat blood level of 1,25-dihydroxyvitamin D [1,25-(OH)2D] without raising the blood calcium value. ABL also significantly augmented the carboxylated osteocalcin (Gla-Ocn) in the blood and bone that is synthesized by osteoblasts, and increased noncarboxylated …

Pancreatic Ductal Adenocarcinoma (PDAC) is highly resistant to chemotherapy. Effective alternative therapies have yet to emerge, as chemotherapy remains the best available systemic treatment. However, the discovery of safe and available adjuncts to enhance chemotherapeutic efficacy can still improve survival outcomes. We show that a hyperglycemic state substantially enhances the efficacy of conventional single- and multi-agent chemotherapy regimens against PDAC. Molecular analyses of tumors exposed to high glucose levels reveal that the expression of GCLC (glutamate-cysteine ligase catalytic subunit), a key component of glutathione biosynthesis, is diminished, which in turn augments oxidative anti-tumor damage by chemotherapy. Inhibition of GCLC phenocopies …

Rational
Acute intermittent hypoxia (AIH) shows promise for enhancing motor recovery in chronic spinal cord injuries and neurodegenerative diseases. However, human trials of AIH have reported significant variability in individual responses.
Objectives
Identify individual factors (eg, genetics, age, and sex) that determine response magnitude of healthy adults to an optimized AIH protocol, acute intermittent hypercapnic-hypoxia (AIHH).
Methods
In 17 healthy individuals (age = 27 ± 5 yr), associations between individual factors and changes in the magnitude of AIHH (15, 1-min O2 = 9.5%, CO2 = 5% episodes) induced changes in diaphragm motor-evoked potential (MEP) amplitude and inspiratory mouth occlusion pressures …

HIV-exposed seronegative individuals (HESIs) are a small fraction of persons who are multiply exposed to human immunodeficiency virus (HIV), but do not exhibit serological or clinical evidence of HIV infection. In other words, they are groups of people maintaining an uninfected status for a long time, even after being exposed to HIV several times. The long-term non-progressors (LTNPs), on the other hand, are a group of HIV-infected individuals (approx. 5%) who remain clinically and immunologically stable for an extended number of years without combination antiretroviral therapy (cART). Meanwhile, elite controllers are comprise a much lower number (0.5%) of HIV-infected persons …

Crosstalk Between Diacylglycerol Kinase And Protein Kinase A In The Regulation Of Airway Smooth Muscle Cell Proliferation, Miguel Angel Hernandez-Lara, Santosh Kumar Yadav, Stanley Conaway, Sushrut D. Shah, Raymond B. Penn, Phd, Deepak A. Deshpande, Phd
Center for Translational Medicine Faculty Papers
Background: Diacylglycerol kinase (DGK) regulates intracellular signaling and functions by converting diacylglycerol (DAG) into phosphatidic acid. We previously demonstrated that DGK inhibition attenuates airway smooth muscle (ASM) cell proliferation, however, the mechanisms mediating this effect are not well established. Given the capacity of protein kinase A (PKA) to effect inhibition of ASM cells growth in response to mitogens, we employed multiple molecular and pharmacological approaches to examine the putative role of PKA in the inhibition of mitogen-induced ASM cell proliferation by the small molecular DGK inhibitor I (DGK I).
Methods: We assayed cell proliferation using CyQUANT™ NF assay, protein expression …

Background: The swinging flashlight test (SFT) is one of the most prominent clinical tests for detecting the relative afferent pupillary defect (RAPD). A positive RAPD localizes the lesion to the affected afferent pupil pathway and is a critical part of any ophthalmic exam. Testing for an RAPD, however, can be challenging (especially when small), and there is significant intrarater and interrater variability.
Methods: Prior studies have shown that the pupillometer can improve the detection and measurement of RAPD. In our previous research, we have demonstrated an automatic SFT by utilizing virtual reality (VR), named VR-SFT. We applied our methods to …

Background Cigarette smoking remains a primary cause of chronic lung diseases. After a steady decline, smoking rates have recently increased especially with the introduction of newer electronic nicotine delivery devices, and it is also emerging that dual- or poly-product usage is on the rise. Additionally, with the introduction of IQOS (a heated tobacco product) globally, its impact on human health needs to be investigated. In this study we tested if dual exposure (cigarette smoke (CS)+IQOS) is detrimental to lung epithelial cells when compared with CS or IQOS exposure alone.
Methods Human airway epithelial cells (BEAS-2B) were exposed to either CS, …

Hyperspectral imaging (HSI) technology has been applied in a range of fields for target detection and mixture analysis. While HSI was originally developed for remote sensing applications, modern uses include agriculture, historical document authentication, and medicine. HSI has also shown great utility in fluorescence microscopy. However, traditional fluorescence microscopy HSI systems have suffered from limited signal strength due to the need to filter or disperse the emitted light across many spectral bands. We have previously demonstrated that sampling the fluorescence excitation spectrum may provide an alternative approach with improved signal strength. Here, we report on the use of excitation-scanning HSI …

Crimean-Congo Hemorrhagic Fever Virus (CCHFV) is a tick-borne virus that causes severe hemorrhagic disease in humans. There is a great need for effective vaccines and therapeutics against CCHFV for humans, as none are currently internationally approved. Recently, a monoclonal antibody against the GP38 glycoprotein protected mice against lethal CCHFV challenge. To show that GP38 is required and sufficient for protection against CCHFV, we used three inactivated rhabdoviral-based CCHFV-M vaccines, with or without GP38 in the presence or absence of the other CCHFV glycoproteins. All three vaccines elicited strong antibody responses against the respective CCHFV glycoproteins. However, only vaccines containing GP38 …
