Physical Changes Of Biomacromolecules Upon Covalent Surface Immobilization, Bianca Mercado Velez, Vaishali Sharma, Seth Kriz, Erico T. F. Freitas, Paul Goetsch, Caryn Heldt

Michigan Tech Research Data

Immobilization of large biomacromolecules is often required for analytical quantification and physicochemical characterization. However, immobilization can alter the structure and size of the particles being studied. Here, two exosomes (derived from HEK-293 and MDA-MB-231 cells) and three viral particles (suid herpesvirus 1, xenotropic murine leukemia virus, and porcine parvovirus) were immobilized to different covalent chemistries to understand how surface chemistry influences particle deformation during immobilization. The surface chemistries explored were: (i) NHS (N-hydroxysulfosuccinimide) and EDC (1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride), and (ii) poly-l-lysine (PLL) and glutaraldehyde (GA). Morphological changes in biomolecules following immobilization were quantified by measuring the height-to-diameter (H/D) ratios attained …

Penalty Box: The Eighth Amendment’S Role In The Fbar Penalties Game, Tessa B. Walter

Georgia State University Law Review

A sharp disagreement has emerged among federal circuit courts regarding the application of the Eighth Amendment’s Excessive Fines Clause to penalties for failing to file a Foreign Bank Account Report (FBAR). This has created legal uncertainty for individuals with foreign financial interests. The resulting circuit split leads to disparate outcomes, where the constitutionality of a penalty is dependent on the jurisdiction in which it is challenged.

The divergence in judicial opinion centers on a fundamental question: Whether the substantial civil penalties for willful FBAR violations constitute a punitive “fine” or a remedial measure intended to compensate the government. The statutory …

Dynamics Of The Airborne Phase In Discus Throwing, Andreas Maheras

Track and Field Faculty Publications

From a mechanics point of view, the execution of the airborne phase in discus throwing can affect the execution of the delivery phase, and eventually the distance thrown. It is not very important to minimize the time it takes to complete the airborne phase or how fast the thrower turns in the middle. The important element in this phase is to create the conditions for a quick planting of the left foot in the front of the ring, while at the same time keeping the shoulder axis towards the thrower's right in the final double support phase. That, can be …

Numerical Modeling Of The Magnetic Vector Potential And The Associated Electromagnetic Momenta, John Adams, Christopher L. Duston

Physics Faculty Publications

The idea that the magnetic vector potential A is associated with stored electromagnetic momenta dates back to Maxwell himself. Here, we present numerical modeling results that illustrate the connection between A and associated linear and angular electromagnetic momenta, expanding on previous work which mostly considered examples that could be analytically solved. We first focus on a stationary point charge q interacting with the magnetic fields of a solenoid, separately calculating A(r) and the electromagnetic momentum added to the system in bringing q to r from a distant location where ⁠A ≈ 0. We then model the …

Motherly Love: A Critical Autoethnography On Identity Formation Through Mental Illness In Maternal Bonds, Ellie E. Monge

Communication Studies

This critical autoethnography is an examination of my personal narrative on how growing up with a mother with mental illness formed my identity as a woman, and as a daughter. I utilize the lens of communication scholarship to understand the effects that this interpersonal relationship had on communication patterns, and ideology. Through personal, and societal analysis the discourse adds to how gendered expectations of womanhood, motherhood, family communication patterns, and dominant mental health rhetoric shape identity for daughters raised in the absence of maternal stability. I implore Family Systems Theory, Family Communication Patterns Theory, Muted Group Theory, and scholarship on …

Engineering Enac Constructs To Examine Pip2 And Ubiquitin Competition On Enac Regulation And Stability, Lacie Johnson

Chemistry & Biochemistry Undergraduate Honors Theses

The epithelial sodium channel (ENaC) plays a critical role in sodium homeostasis, fluid balance, and blood pressure regulation. ENaC activity is tightly controlled by post-translational mechanisms, including ubiquitination-mediated degradation and phosphatidylinositol 4,5-bisphosphate (PIP2) dependent channel activation. PIP2 is a phospholipid necessary to facilitate the maximal channel opening. Previous studies suggest that intracellular PIP2 binding sites are located in proximity to ubiquitination sites on ENaC subunits, raising the possibility of PIP2 binding to influence channel stability and function. This thesis aimed to engineer and validate molecular tools capable of examining the interplay between PIP2 binding and ubiquitination in ENaC regulation. A …
