Gramseq-Dta: A Grammar-Based Drug-Target Affinity Prediction Approach Fusing Gene Expression Information, Kasul Debnath, Pratip Rana, Preetam Ghosh

Computer Science Faculty Publications

Drug–target affinity (DTA) prediction is a critical aspect of drug discovery. The meaningful representation of drugs and targets is crucial for accurate prediction. Using 1D string-based representations for drugs and targets is a common approach that has demonstrated good results in drug–target affinity prediction. However, these approach lacks information on the relative position of the atoms and bonds. To address this limitation, graph-based representations have been used to some extent. However, solely considering the structural aspect of drugs and targets may be insufficient for accurate DTA prediction. Integrating the functional aspect of these drugs at the genetic level can enhance …

Theses, Dissertations and Capstones

Vaccines are a vital tool in preventing diseases, but their effectiveness varies depending on factors like diet and body weight. Obese individuals often experience reduced vaccine protection, as seen with influenza vaccines, where they have twice the risk of getting the flu compared to healthy-weight individuals after vaccination. This study aims to understand why obesity weakens vaccine effectiveness, focusing on the role of blood-forming stem cells in the bone marrow, known as hematopoietic stem and progenitor cells (HSPCs). These cells are crucial for producing immune cells that defend the body against infections. Previous research has shown that diet-induced obesity alters …

Synthesis Of Tu100 Analogs And Biological Assays, Feyisope Tonye Oladapo

College of Graduate Studies: Theses & Dissertations

TU100 (14-methyl-5H-5,12-epiminobenzo[4,5]cyclohepta[1,2-b]naphthalene-6,11,13(12H)-trione) exhibits exceptional chemotherapeutic properties. It operates via a distinct mechanism that triggers cell death to create cytotoxic effects while concurrently inhibiting topoisomerase I and II. Its efficacy rivals that of well-known chemotherapeutic drugs like Daunorubicin. The distinctive characteristics of TU100 have led to initiatives aimed at creating structurally similar compounds to discover even more effective bioactive alternatives.

The analog synthesis incorporated quinoxaline or its derivatives (diphenyl quinoxaline, dipyridinyl quinoxaline, and dibenzophenazine-10,13-dione) that have been shown to have promising chemotherapeutic effects. Synthesizing the hetero naphthoquinones required a multi-step synthetic process, so quinoxaline/ derivatives intermediates are first prepared, then the …

Customary Corruption, Ani B. Satz, Liza Vertinsky Jan 2025

Customary Corruption, Ani B. Satz, Liza Vertinsky

Faculty Articles

For over a hundred years, it has been well-accepted among tort scholars that physicians—as one of the legally recognized professions— determine their own customary practices. Within tort law, and medical malpractice more specifically, customary practice establishes whether physicians breach or uphold the required standard of care toward their patients. The results of our hand-coded examination of decided cases and statutes show a more complex picture. While some states have endeavored to shift the standard away from professional custom, it continues to play a critical, and in many cases a determinative, role in establishing physician liability in most states.

Using illustrative …

Amorphous Quininium Aspirinate From Neat Mechanochemistry: Diffracting Nanocrystalline Domains And Quick Recrystallization Upon Exposure To Solvent Vapours, Silvina Pagola, James Howard, Johannes Merkelbach, Danny Stam

Chemistry & Biochemistry Faculty Publications

Quininium aspirinate is mechanochemically prepared as a crystalline solid by liquid-assisted grinding, or as an amorphous phase (as determined by X-ray powder diffraction), by neat grinding or neat ball milling. Our previous work demonstrated using FT-IR spectroscopy that a mechanochemical reaction had occurred in the mechanically treated neat mixtures. Herein is reported that microcrystal electron diffraction (microED) afforded the discovery of two diffracting micron-size particles in the amorphous powder synthesized by manual grinding, among a majority of non-diffracting particles. Remarkably, microED data of one of them led to the known lattice parameters of quininium aspirinate. Furthermore, this so-called 'X-ray amorphous' …
