Dissociating Reading And Auditory Comprehension In Persons With Aphasia, Rachael M. Harrington, Sigfus Kristinsson, Janina Wilmskoetter, Natalie Busby, Dirk B. Den Ouden, Chris Rorden, Julius Fridriksson, Leonardo Bonilha

Communication Sciences and Disorders Faculty Articles and Research

Language comprehension is often affected in individuals with post-stroke aphasia. However, deficits in auditory comprehension are not fully correlated with deficits in reading comprehension and the mechanisms underlying this dissociation remain unclear. This distinction is important for understanding language mechanisms, predicting long-term impairments and future development of treatment interventions. Using comprehensive auditory and reading measures from a large cohort of individuals with aphasia, we evaluated the relationship between aphasia type and reading comprehension impairments, the relationship between auditory versus reading comprehension deficits and the crucial neuroanatomy supporting the dissociation between post-stroke reading and auditory deficits. Scores from the Western Aphasia …

Simple Summary

Vestibular schwannoma (VS), benign cranial nerve sheath tumors of the vestibulocochlear nerve, lack efficacious systemic therapies, especially if they develop in a NF2-related schwannomatosis (NF2) background. They cause hearing loss, tinnitus and balance problems. Metastasis associated in colon cancer 1 (MACC1) is a key driver of metastasis. Although MACC1 expression is associated with highly malignant tumors and VS are considered benign, both are attached to the HGF/MET signaling pathway and MACC1 is a candidate gene localized at a hearing loss-related gene locus. Therefore, it was investigated whether MACC1 might be involved in VS pathogenesis. Surprisingly, MACC1 expression …

Anterior Cruciate Ligament Hybrid Remnant Preservation Reconstruction Demonstrates Similar Outcomes As Traditional Reconstruction After 6 Months: A Randomized Control Trial, Joshua P. Castle, Eleftherios L. Halkias, Brittaney Pratt, Ashley Frei, Matthew A. Gasparro, Vasilios Moutzouros

Medical Student Research Symposium

Background

The anterior cruciate ligament (ACL) is often debrided during reconstruction (ACLR) to improve visualization. However, remnant ACL tissue contains nerve fibers and including remnant tissue in ACLR could provide benefit. Therefore, a technique was developed that preserves the tibial remnant and incorporates it into ACLR: Hybrid Remnant Preservation Reconstruction (HRPR) ACLR. This study compares HRPR-ACLR to traditional reconstruction by comparing patient reported outcomes and complications.

Methods

Patients presenting to one surgeon's clinic with an ACL injury are screened. Exclusion criteria are patient age<14 years, multi-ligament injury, chronic tears, and revision ACLR. Patients are consented and randomized to HRPR or traditional ACLR. Demographics, patient-reported outcomes, range of motion (ROM) and complications were collected.

Results

Thirty-three patients were included, 20 HRPR and 13 controls. No demographic differences were noted. PROMIS-PF, …

School of Medicine Faculty Publications

The increased risk for acquiring secondary illnesses in people living with HIV (PLWH) has been associated with immune dysfunction. We have previously found that circulating monocytes from PLWH display a trained phenotype. Here, we evaluated the metabolic profile of these cells and found increased mitochondrial respiration and glycolysis of monocyte-derived macrophages (MDMs) from PLWH. We additionally found that cART shifted the energy metabolism of MDMs from controls toward increased utilization of mitochondrial respiration. Importantly, both downregulation of IKAROS expression and inhibition of the mTOR pathway reversed the metabolic profile of MDMs from PLWH and cART-treated control-MDMs. Altogether, this study reveals …

Faculty, Staff and Student Publications

The gate-type carbon nanotubes cathodes exhibit advantages in long-term stable emission owing to the uniformity of electrical field on the carbon nanotubes, but the gate inevitably reduces the transmittance of electron beam, posing challenges for system stabilities. In this work, we introduce electron beam focusing technique using the self-charging SiN_x/Au/Si gate. The potential of SiN_x is measured to be approximately −60 V quickly after the cathode turning on, the negative potential can be maintained as the emission goes on. The charged surface generates rebounding electrostatic forces on the following electrons, significantly focusing the electron beam on the …

Avaren-Fc, A Novel Immunotherapeutic, Recruits Nk Cells In B16f10 Melanoma Tumor Tissue, Sreevatsa Vemuri, Katarina Mayer, Nobuyuki Matoba

Posters-at-the-Capitol

Melanoma is the fifth most common cancer in the US, with limited effective immunotherapeutic options available for patients. Avaren-Fc (AvFc) is a novel experimental immunotherapeutic agent with a unique “lectibody” property. It is capable of targeting cancer cells through the selective recognition of high mannose glycans, which are aberrantly overrepresented on the surface of malignant cells. AvFc can interact with circulating effector immune cells equipped with Fc receptors, such as natural killer (NK) cells to induce antibody-dependent cell-mediated cytotoxicity (ADCC) and kill cancer cells. Previous work has shown that AvFc effectively induces ADCC activity against B16F10 cancer cells in vitro …

School of Medicine Faculty Publications

Gene delivery to, and expression in, the mouse brain is important for understanding gene functions in brain development and disease, or testing gene therapies. Here, we describe an approach to express a transgene in the mouse brain in a cell-type-specific manner. We use stereotaxic injection of a transgene-expressing adeno-associated virus into the mouse brain via the intracerebroventricular route. We demonstrate stable and sustained expression of the transgene in neurons of adult mouse brain, using a reporter gene driven by a neuron-specific promoter. This approach represents a rapid, simple, and cost-effective method for global gene expression in the mouse brain, in …

Glycosylphosphatidylinositols (GPIs) anchor over 150 proteins as GPI-anchored proteins (GPI-APs) with crucial roles in diverse biological processes. The highly conserved biosynthesis of GPI-APs involves precise steps with at least 21 genes, categorized as PIG and PGAP genes. Pathogenic variants in these genes are linked to human diseases, highlighting the importance of each biosynthesis step. PGAP2 stands out among these genes due to its association with an expanded clinical spectrum of neurodevelopmental disorder (NDD) phenotypes with biallelic pathogenic variants. We present four patients from two families, one consanguineous and the other nonconsanguineous, each displaying distinct clinical presentations, including intellectual disability, hyperphosphatasia, …

The Role Of Liver-Specific Transcription Factor Hnf4 In Reprogramming Of Fibroblasts, Mary Odubote

Masters Theses

The mammalian liver, a vital organ with complex functions, relies on a network of transcription factors to regulate gene expression. Fusion of hepatoma cells with fibroblasts often leads to gene extinction, silencing approximately 400 liver-enriched genes, including critical transcription factors such as HNF4. Previous studies revealed that ectopic expression of HNF4 in fibroblasts failed to prevent the extinction of SERPINA1, a liver-specific gene, upon subsequent fusion with hepatoma cells. Here, we sought to investigate the extent to which ectopic expression of HNF4 can reprogram fibroblast cells and prevent gene extinction in hybrid cells.

Using whole-genome expression analysis, we compared RAT1 …

Actin Depolymerization Of Tenocytes Promotes A Tendinosis-Like Gene Expression, Kameron Inguito, Ba, Valerie West, Karl Matthew Ebron, Justin Parreno, Phd

Alpha Omega Alpha Research Symposium Posters

Optimal cellular mechanotransduction is essential for tendon matrix homeostasis. We recently developed an in vivo rat model of tendinosis, where the plantaris tendon are overloaded through ablation of the synergistic Achilles tendon. Using this model we determined that tissue overload disrupts matrix-cell interactions, which results in under-stimulation of tendon cells (tenocytes) (Fig.1)

Using an ex vivo model of tendon stress deprivation by maintaining tail tendon fascicles in floating culture we showed that tenocyte under-stimulation results in destabilization of filamentous (F-)actin (Fig.2). F-actin destabilization coincides with tendinosis-like gene expression: downregulation of tenogenic genes (Col1, Tnc, asma, Scx), upregulation of chondrogenic (Acan, …

Advancing School Nursing Practice: A Novel Approach To Screening For Gastrointestinal Disorders In Children, Ashley Bunting, Isabella Cavlan
