Serendipitous Supernormality, Behzad B. Pavri, Eitan Frankel

Division of Cardiology Faculty Papers

We describe a patient who underwent AV node modification to create complete heart block in the setting of incessant, ablation-and-drug-refractory, symptomatic atypical atrial flutter. His dual chamber defibrillator (previously implanted for resuscitated cardiac arrest) was programmed to the VVIR mode at a faster pacing rate of 85 bpm. Serendipitously, this rate was an almost exact factorial of his flutter rate of 250-260 bpm. This resulted in every 6th flutter wave falling in the supernormal period, resulting in fixed-coupled supraventricular bigeminy and trigeminy in the setting of complete heart block. Reprogramming the pacing rate to 75 bpm abolished bigeminy and trigeminy.

The Impact Of Biomaterial Characteristics On Macrophage Phenotypes In Tissue Engineering: A Review, Julian Jackson, Hani Samarah, William Palmer, Zachary Kaplan, Marianna Nicodem, Parvesh Kumar, Spenser Short, Kelly Bridgham, Larry Harshyne, Joseph Curry

Department of Otolaryngology - Head and Neck Surgery Faculty Papers

Macrophages are highly plastic cells central to pathogen removal, tissue regeneration, and inflammation, making them key targets in biomaterial design for improved clinical outcomes. Foreign body responses (FBRs) to implanted biomaterials often involve excessive macrophage-mediated inflammation, leading to fibrotic encapsulation, infection, and implant failure. Advances in tissue engineering demonstrate that macrophage polarization - the transition from pro-inflammatory M1 to anti-inflammatory M2 phenotypes - can be influenced by biomaterial properties to mitigate these responses and enhance regeneration. This review synthesizes the relationship between biomaterial properties, such as surface chemistry, structure, and stiffness, and their ability to modulate macrophage behavior. Key innovations, …

Structural Insights Into The Function, Dysfunction And Modulation Of Kv3 Channels, Manuel Covarrubias, Qiansheng Liang, Linh Nguyen-Phuong, Kyle J. Kennedy, Tyler D. Alexander, Ms, Andrew Sam

Department of Neuroscience Faculty Papers

The third subfamily of voltage-gated K⁺ (Kv) channels includes four members, Kv3.1, Kv3.2, Kv3.3 and Kv3.4. Fast gating and activation at relatively depolarized membrane potentials allows Kv3 channels to be major drivers of fast action potential repolarization in the nervous system. Consequently, they help determine the fast-spiking phenotype of inhibitory interneurons and regulate fast synaptic transmission at glutamatergic synapses and the neuromuscular junction. Recent studies from our group and a team of collaborators have used cryo-EM to demonstrate the surprising gating role of the Kv3.1 cytoplasmic T1 domain, the structural basis of a developmental epileptic encephalopathy caused by the …

Vadhera, Mouayad Masalkhi, Ryung Lee, Chirag Gowda, Ram Jagadeesan, Nasif Zaman, Alireza Tavakkoli

SKMC Student Presentations and Publications

Exposure to microgravity causes rapid bone loss and muscle atrophy, posing serious challenges for long-duration spaceflight. In response, NASA developed countermeasures such as Lower Body Negative Pressure (LBNP) to simulate gravitational loading on astronauts’ lower extremities. LBNP, often combined with exercise, has proven effective in mitigating musculoskeletal degradation during bed rest analogs. This opinion paper argues that LBNP’s success in preserving bone mass and muscle function in microgravity can be translated to improve re- covery after orthopedic arthroplasty on Earth. We draw physiological parallels between microgravity-induced musculoskeletal disuse and the postoperative period following total joint replacement, during which reduced weight-bearing …

Hepatic Manifestations Following Gene Therapy, Akash Roy, Shalini Bansal, Anand Kulkarni, K. Rajender Reddy

SKMC Student Presentations and Publications

Gene therapy involves the introduction of genetic materials, most commonly using viral vectors, to alter gene expression to ameliorate or cure disease symptoms with minimal adverse events. While interest in gene therapy has been on the increase, concerns have arisen about the potential for hepatotoxicity, which arises from diverse mechanisms. While viral vectors can produce dose-dependent hepatotoxicity secondary to integration, immune responses appear to be the primary driving mechanism. A mild increase in aminotransferases is the most common hepatic manifestation, occurring variably in 20%-80%, while there has been rare progress to acute liver failure. The occurrence of hepatotoxicity is unpredictable …

Environmental Exposures And Familial Background Alter The Induction Of Neuropathology And Inflammation After Sars-Cov-2 Infection, Debotri Chatterjee, Drishya Kurup, Richard Jay Smeyne

Department of Neuroscience Faculty Papers

Post-infection sequela of several viruses have been linked with Parkinson's disease (PD). Here, we investigated whether mice infected with SARS-CoV-2 alone or in combination with two putative Parkinsonian toxins, MPTP and paraquat, increased the susceptibility to develop Parkinsonian pathology. We also examined if G2019S LRRK2 mice had any change in sensitivity to SARS-CoV-2 as well as if vaccination against this virus altered any neuropathology. Infection with WA-1/2020 or Omicron B1.1.529 strains sensitized both WT and G2019S LRRK2 mice to the neuropathological effects of a subtoxic exposure to MPTP, but not paraquat. These neuropathologies were rescued in WT mice vaccinated with …
