Faculty, Staff and Student Publications

The indispensable role of the SARS-CoV-2 main protease (Mpro) in the viral replication cycle and its dissimilarity to human proteases make Mpro a promising drug target. In order to identify the non-covalent Mpro inhibitors, we performed a comprehensive study using a combined computational strategy. We first screened the ZINC purchasable compound database using the pharmacophore model generated from the reference crystal structure of Mpro complexed with the inhibitor ML188. The hit compounds were then filtered by molecular docking and predicted parameters of drug-likeness and pharmacokinetics. The final molecular dynamics (MD) simulations identified three effective candidate inhibitors (ECIs) capable of maintaining …

Faculty, Staff and Student Publications

INTRODUCTION: Delinquent behaviors are risky behaviors that increase during puberty and reach their highest peak in late adolescence. It has been proposed that poor decision-making and theory of mind (ToM) are key cognitive processes implicated with delinquency during adolescence, affecting evaluation of risks and impairing appreciation of social norms. Nevertheless, it is not yet clear whether adolescent offenders who are subjected to provisional deprivation of liberty due to conflict with the law (adolescents in conflict with the law [ACL]) might, in fact, present a specific profile with regard to these cognitive processes.

OBJECTIVES: To assess deliberative decision-making and ToM among …

Differentiation therapy using small molecules is a promising strategy for improving the prognosis of glioblastoma (GBM). Histone acetylation plays an important role in cell fate determination. Nevertheless, whether histone acetylation in specific sites determines GBM cells fate remains to be explored. Through screening from a 349 small molecule-library, we identified that histone deacetylase inhibitor (HDACi) MS-275 synergized with 8-CPT-cAMP was able to transdifferentiate U87MG GBM cells into neuron-like cells, which were characterized by cell cycle arrest, rich neuron biomarkers, and typical neuron electrophysiology. Intriguingly, acetylation tags of histone 3 at lysine 9 (H3K9ac) were decreased in the promoter of multiple …

Survival of pediatric AML remains poor despite maximized myelosuppressive therapy. The pneumocystis jiroveci pneumonia (PJP)-treating medication atovaquone (AQ) suppresses oxidative phosphorylation (OXPHOS) and reduces AML burden in patient-derived xenograft (PDX) mouse models, making it an ideal concomitant AML therapy. Poor palatability and limited product formulations have historically limited routine use of AQ in pediatric AML patients. Patients with de novo AML were enrolled at two hospitals. Daily AQ at established PJP dosing was combined with standard AML therapy, based on the Medical Research Council backbone. AQ compliance, adverse events (AEs), ease of administration score (scale: 1 (very difficult)-5 (very easy)) …

Shared Responsibility: Conceptualising How A Public Health Approach May Enhance Police Response To Missing Persons, Katie Gambier-Ross, Joe Apps Dr, Sarah Wayland Dr

International Journal of Missing Persons

When a person is reported missing there are substantial costs for the individual, their family and society. This paper conceptualises the experience of missing persons episodes, through a public health approach. This then allows police, stakeholders and the community to engage in discussions about who is vulnerable to going missing by intervening in a way that addresses risk. Historically, a missing persons episode involves an absence, typically followed by police involvement in consultation with next of kin with establishing the whereabouts of the missing person being the primary focus. Yet, the risk factors of going missing relate more to the …

The coronavirus disease 2019 (COVID-19) pandemic and associated increase in family care responsibilities resulted in unsustainable personal and professional workloads for infectious diseases (ID) faculty on the front lines. This was especially true for early-stage faculty (ESF), many of whom had caregiving responsibilities. In addition, female faculty, underrepresented in medicine and science faculty and particularly ESF, experienced marked declines in research productivity, which significantly impacts career trajectories. When combined with staffing shortages due to an aging workforce and suboptimal recruitment and retention in ID, these work-life imbalances have brought the field to an inflection point. We propose actionable recommendations and …

Difference Of Elbow Extension Velocity During Flat And Mound Throwing, Omar Arizpe, Joshua Perez, Bryon C. Applequist

International Journal of Exercise Science: Conference Proceedings

In baseball, players encounter varying forms of throwing that is dependent upon position. Pitchers often throw on a mound, while position players are seen throwing from a flat ground. The throwing motion of a baseball consists of six phases: wind-up, stride, late cocking, acceleration, deceleration, and follow through. Each of these different phases consists of velocities being produced from the lower body through the elbow, which contributes to a potential cause of throwing arm injuries. Given the prominence of elbow injuries to pitchers, investigation into the solution to reducing arm injuries has continued to gain traction. PURPOSE: The purpose …

Pressurized Device For Mitigating Atrophy In Soleus During Long-Duration Spaceflight, Ramona Tovar Briones, Kimhab Sor, Breandrea Diaz, Dona Varghese, Benjamin Easter, Hunter Alvis, Brandon R. Rigby

International Journal of Exercise Science: Conference Proceedings

A major concern with long duration spaceflight, skeletal muscle atrophy is most detrimental in lower limb musculature, particularly in muscles critical for proper gait, such as the soleus. The decline of muscle activation and the suppression of sensory input from plantar sole mechanoreceptors can add to the attenuation of skeletal muscle health during spaceflight. More specifically, inhibition of sensory input from sole receptors, such as with gravitational unloading, decreases selective activation, thereby negatively affecting muscle tone and inevitably resulting in lower limb atrophy. PURPOSE: To design, fabricate, and test a specialized boot with an insole that applies oscillating pneumatic …
