Optimization Of A Non-Invasive Temporary Deafferentation Protocol To Improve Upper Extremity Rehabilitation, Victoria Cuello, Kelsey Baker Sep 2023

Optimization Of A Non-Invasive Temporary Deafferentation Protocol To Improve Upper Extremity Rehabilitation, Victoria Cuello, Kelsey Baker

Research Symposium

Background: After a spinal cord injury neural structures that survive reorganize. The brain “ignores” past associations with weaker muscles below the level of injury so stronger, spared muscles take over cortical maps of weaker muscles. Temporary Deafferentation (TD) is a method that utilizes short-term anesthesia, such as over-the-counter lidocaine cream, to inactivate sensation pathways from stronger muscles so that the brain releases inhibition that was placed on weaker muscles, thereby strengthening them. There has been research supporting TD approaches to rehabilitation; however, there is not an established protocol to apply TD in a clinical setting. Here, we seek to optimize …

Mucin Muc13 And Yap1 Correlate With Poor Survival In Colorectal Cancer, Sudhir Kotnala, Anupam Dhasmana, Kyle Doxtater, Meena Jaggi, Murali M. Yallapu, Manish Tripathi, Subhash C. Chauhan

Research Symposium

Background: Metastatic disease contributes to over 90% of cancer-associated deaths. Colorectal cancer (CRC), the second lethal malignancy, has the greatest incidence and mortality rates in the Southern United States. Over 40-50% of CRC patients acquire metastasis at some point throughout their disease's progression. CRC survival rate drops from 90%-14% when the disease is confined within the colon and therefore “early diagnosis” becomes imperative to determine timely and quality treatments. We have identified that MUC13 protein translocate to nucleus along with transcription factor Yes-Associated Protein 1 (YAP1) during anchorage independent conditions (metastatic phenotype). YAP1 is known to be overexpressed in CRC …

Research Symposium

Pancreatic cancer (PanCa) is a third leading cause of cancer related deaths in US. Unlike other cancers, PanCa is highly resistant to TNF-related apoptosis-inducing ligand (TRAIL) that emerges as one of the most-promising therapy in clinical trials. Our group has previously identified microRNA-145 (miR-145) is downregulated in PanCa, the restoration of which inhibits tumor growth and enhances gemcitabine sensitivity. In this study, we have observed that miR-145 restoration in PanCa cells renders them sensitive to TRAIL treatment. Therefore, we have engineered unique superparamagnetic nanoparticles (SPs) for co-delivering miR-145 and TRAIL in PanCa for improving their therapeutic response to TRAIL. The …
