The COVID-19 pandemic has resulted in preventative measures and has led to extensive changes in lifestyle for the vast majority of the American population. As the pandemic progresses, a growing amount of evidence shows that minority groups, such as the Deaf community, are often disproportionately and uniquely affected. Deaf people are directly affected in their ability to personally socialize and continue with daily routines. More specifically, this can constitute their ability to meet new people, connect with friends/family, and to perform in their work or learning environment. It also may result in further mental health changes and an increased reliance on technology. The impact of COVID-19 on the Deaf community in clinical settings must also be considered. This includes changes in policies for in-person interpreters and a rise in telehealth. Often, these effects can be representative of the pre-existing low health literacy, frequency of miscommunication, poor treatment, and the inconvenience felt by Deaf people when trying to access healthcare. Ultimately, these effects on the Deaf community must be taken into account when attempting to create a full picture of the societal shift caused by COVID-19.

Lyme disease is a common tick-borne illness caused by the Gram-negative bacterium Borrelia burgdorferi. An outer membrane protein of Borrelia burgdorferi, P66, has been suggested as a possible target for Lyme disease treatments. However, a lack of structural information available for P66 has hindered attempts to design medications to target the protein. Therefore, this study attempted to find methods for expressing and purifying P66 in quantities that can be used for structural studies. It was found that by using the PelB signal sequence, His-tagged P66 could be directed to the outer membrane of Escherichia coli, as confirmed by an anti-His Western blot. Further attempts to optimize P66 expression in the outer membrane were made, pending verification via Western blotting. The ability to direct P66 to the outer membrane using the PelB signal sequence is a promising first step in determining the overall structure of P66, but further work is needed before P66 is ready for large-scale purification for structural studies.

This qualitative study sought to investigate the potential reaction between the 3,3',5,5'-tetramethylbenzidine (TMB) radical and LAF-1 RGG, the N-terminus domain of an RNA helicase which functions as a coacervating intrinsically disordered protein. The study was performed by adding horseradish peroxidase to a solution containing TMB and either LAF-1 or tyrosine in various concentrations, and monitoring the output through UV-Vis spectroscopy. The reacted species was also analyzed via MALDI-TOF mass spectrometry. UV-Vis spectroscopic monitoring showed that in the presence of LAF-1 or tyrosine, the reaction between HRP and TMB occurred more quickly than the control, as well as in the highest concentration of LAF-1, the evolution of a peak at 482 nm. The analysis through MALDI-TOF spectrometry showed the development of a second peak likely due to the reaction between LAF-1 and TMB, as the Δ between the peaks is 229 Da and the size of the TMB species is 240 Da.
