Unveiling The Unique Ras Isoform And Domain Specific Regulation Of Braf Kinase, Tarah Trebino

Theses and Dissertations

BRAF kinase is a key member of the MAPK pathway, important for cell growth and division. Upstream signals promote BRAF activation by interaction with the membrane bound GTPase, RAS, which leads to relief of autoinhibition and dimerization. The N-terminal regulatory domains of BRAF, including the BRAF specific region (BSR), the RAS binding domain (RBD), and the cysteine rich domain (CRD), govern the conformational state of the cytosolic, autoinhibited monomer and drive the RAS-RAF interaction. Active BRAF phosphorylates and activates its substrate MEK, which in turn phosphorylates and activates ERK. Mutations in RAS and BRAF are the cause of many cancers …

Synthesis And Characterization Of Bio Based Amphiphilic Molecules, Vandana Singh

Theses and Dissertations

Among various molecular self-assemblies, low molecular weight gelators (LMWGs), that can form gels in organic solvents/water/oils, have gained much research attention due to their huge potential applications. Generally, gels are soft nanomaterials formed by the self-assembly of amphiphilic molecules into a three-dimensional fibrous network entrapping the solvent.

As these gels are formed by self-assembly via non-covalent interactions they are reversible and differ from macromolecular gels. To synthesize LMWGs, biomolecules such as fats, oils, fatty acids, lignocelluloses, sugars, amino acids, and peptides are commonly used as their inherent property favors self-assembly. In the current scenario, interest in synthesizing bio-based gelators has …

Cancer Treatment By Targeting Hdac4 Translocation Induced By Microsecond Pulsed Electric Field Exposure: Mechanistic Insights Through Kinases And Phosphatases, Zahra Safaei

Theses and Dissertations

Epigenetic modifications, arising from sub-cellular shifts in histone deacetylase (HDAC) activity and localization, present promising strategies for diverse cancer treatments. HDACs, enzymes responsible for post-translational histone modifications, induce these epigenetic changes by removing acetyl groups from ε-N-acetyl-lysine residues on histones, thereby suppressing gene transcription. Within the HDAC group, class IIa HDACs are notable for their responsiveness to extracellular signals, bridging the gap between external stimuli, plasma membrane, and genome through nuclear-cytoplasmic translocation. This localization offers two significant mechanisms for cancer treatment: nuclear accumulation of HDACs represses oncogenic transcription factors, such as myocyte-specific enhancer factor 2C (MEF2C), triggering various cell death …

Development Of A Xenograft For Annular Repair Using Pulsed Electric Field Exposures For Enhanced Decellularization, Prince Mensah Kwaku Atsu

Theses and Dissertations

Severe back injuries and chronic pain necessitate surgical replacement of damaged intervertebral disc (IVD) cartilage in advanced disease stages.

Through Their Eyes: Illuminating The Nature Of Animal Use In Conservation Research Through An Analysis Of Peer-Reviewed Literature In The Journal Conservation Biology, Sarah Hollmann

Theses and Dissertations

Non-human animals habitually have been treated as a resource in the service of humans and human-driven values. The field of conservation is not immune to this fact. But, because conservation is seemingly dedicated to the saving and protection of species and nature, until recently the field historically has been given a pass for the use and treatment of animals that are done “in the name of conservation”. This treatment is evident in common conservation practices such as capture, captivity, invasive sampling, aversive treatment, experimental manipulation, and intentional killing. A principal question we are asking is how individual animals are impacted …

Budget Capping Health Care: Its Impact On Health, Susan Chen

Theses and Dissertations

The goal of a budget cap on healthcare is to constrain total healthcare expenditure without compromising quality. This paper examines the impacts of budget capping on health and behavioral health outcomes, exploiting the completed Maryland All-Payer Model and the ongoing, extensional Maryland Total Cost of Care model, both of which capped healthcare budgets in Maryland. I use data from 2011-2021 surveys of the Behavioral Risk Factor Surveillance system and generalized difference-in-difference regression models to find that budget capping improves health and behavioral health outcomes with a greater favorable effect during the Maryland Total Cost of Care model.
