Computational Investigation Of The Bioactive Selenium Compounds Ebselen And Selenious Acid, Sonia Antony
Computational Investigation Of The Bioactive Selenium Compounds Ebselen And Selenious Acid, Sonia Antony
Chemistry & Biochemistry Theses & Dissertations
Selenium, a toxic element, is required in trace quantities for the proper functioning of biological systems. The experimental mechanistic study of the reactions of ebselen and selenious acid is difficult due to complexity of the reaction mixtures and the presence of short-lived intermediates. Computational modeling of the reactivity of these species can give us an insight into their mechanisms, but the process is complicated by proton exchanges associated with the mechanistic steps. In gas phase modeling, this may be corrected to a certain level using the solvent assisted proton exchange (SAPE) method. SAPE is a modeling technique that mimics solvent …
Bioinformatics, Thermodynamics And Kinetics Analysis Of An All Alpha Helical Protein With A Gree-Key Topology, Hai Li
Chemistry & Biochemistry Theses & Dissertations
Computational and experimental studies focusing on the role of conserved residues for folding and stability is an active and promising area of research. To further expand our understanding we present the results of a bioinformatics analysis of the death domain superfamily. The death domain superfamily fold consists of six α-helices arranged in a Greek-key topology, which is shared by the all β-sheet immunoglobulin and mixed α/β-plait superfamilies. Our sequence and structural studies have identified a group of conserved hydrophobic residues and corresponding long-range interactions, which we propose are important in the formation and stabilization of the hydrophobic core and native …

A Cell Electrofusion Microfluidic Device Integrated With 3d Thin-Film Microelectrode Arrays, Ning Hu, Jun Yang, Shizhi Qian, Sang W. Joo, Xiaolin Zheng
Mechanical & Aerospace Engineering Faculty Publications
A microfluidic device integrated with 3D thin film microelectrode arrays wrapped around serpentine-shaped microchannel walls has been designed, fabricated and tested for cell electrofusion. Each microelectrode array has 1015 discrete microelectrodes patterned on each side wall, and the adjacent microelectrodes are separated by coplanar dielectric channel wall. The device was tested to electrofuse K562 cells under a relatively low voltage. Under an AC electric field applied between the pair of the microelectrode arrays, cells are paired at the edge of each discrete microelectrode due to the induced positive dielectrophoresis. Subsequently, electric pulse signals are sequentially applied between the microelectrode arrays …
Computational Network Analysis Of The Anatomical And Genetic Organizations In The Mouse Brain, Shuiwang Ji
Computational Network Analysis Of The Anatomical And Genetic Organizations In The Mouse Brain, Shuiwang Ji
Computer Science Faculty Publications
Motivation: The mammalian central nervous system (CNS) generates high-level behavior and cognitive functions. Elucidating the anatomical and genetic organizations in the CNS is a key step toward understanding the functional brain circuitry. The CNS contains an enormous number of cell types, each with unique gene expression patterns. Therefore, it is of central importance to capture the spatial expression patterns in the brain. Currently, genome-wide atlas of spatial expression patterns in the mouse brain has been made available, and the data are in the form of aligned 3D data arrays. The sheer volume and complexity of these data pose significant challenges …
