Mitochondrial Complex Iii Bypass Complex I To Induce Ros In Gpr17 Signaling Activation In Gbm, Sana Kari, Jeyalakshmi Kandhavelu, Akshaya Murugesan, Ramesh Thiyagarajan, Srivatsan Kidambi, Meenakshisundaram Kandhavelu

Department of Chemical and Biomolecular Engineering: Faculty Publications

Guanine nucleotide binding protein (G protein) coupled receptor 17 (GPR17) plays crucial role in Glioblastoma multiforme (GBM) cell signaling and is primarily associated with reactive oxidative species (ROS) production and cell death. However, the underlying mechanisms by which GPR17 regulates ROS level and mitochondrial electron transport chain (ETC) complexes are still unknown. Here, we investigate the novel link between the GPR17 receptor and ETC complex I and III in regulating level of intracellular ROS (ROSi) in GBM using pharmacological inhibitors and gene expression profiling. Incubation of 1321N1 GBM cells with ETC I inhibitor and GPR17 agonist decreased the ROS level, …

Crystalline–Amorphous Nanostructures: Microstructure, Property And Modelling, Binqiang Wei, Lin Li, Lin Shao, Jian Wang

Department of Mechanical and Materials Engineering: Faculty Publications

Crystalline metals generally exhibit good deformability but low strength and poor irradiation tolerance. Amorphous materials in general display poor deformability but high strength and good irradiation tolerance. Interestingly, refining characteristic size can enhance the flow strength of crystalline metals and the deformability of amorphous materials. Thus, crystalline–amorphous nanostructures can exhibit an enhanced strength and an improved plastic flow stability. In addition, high-density interfaces can trap radiation-induced defects and accommodate free volume fluctuation. In this article, we review crystalline–amorphous nanocomposites with characteristic microstructures including nanolaminates, core–shell microstructures, and crystalline/amorphous-based dual-phase nanocomposites. The focus is put on synthesis of characteristic microstructures, deformation …

Evaluating Draft Epa Emissions Models For Laying Hen Facilities, Yijie Xiong, Guoming Li, Brett C. Ramirez, Robert T. Burns, Richard S. Gates

Department of Animal Science: Faculty Publications

In August 2021, the U.S. Environmental Protection Agency (EPA) released draft models to estimate daily NH₃, H₂S, PM₁₀, PM_2.5, and TSP emissions from egg-layer houses (high-rise and manure-belt) and manure storage using inputs of daily mean ambient temperature, relative humidity (RH), and hen inventory. These models were developed from refined datasets generated by the National Air Emissions Monitoring Study fieldwork completed in 2009. Notably, they do not include data for cage-free housing. Currently, 66% of U.S. laying hens are housed in cages; thus, these models, if adopted, will have a substantial impact …

A Leaf-Level Spectral Library To Support High-Throughput Plant Phenotyping: Predictive Accuracy And Model Transfer, Nuwan K. Wijewardane, Huichun Zhang, Jinliang Yang, James C. Schnable, Daniel P. Schachtman, Yufeng Ge

Department of Agronomy and Horticulture: Faculty Publications

Leaf-level hyperspectral reflectance has become an effective tool for high-throughput phenotyping of plant leaf traits due to its rapid, low-cost, multi-sensing, and non-destructive nature. However, collecting samples for model calibration can still be expensive, and models show poor transferability among different datasets. This study had three specific objectives: first, to assemble a large library of leaf hyperspectral data (n=2460) from maize and sorghum; second, to evaluate two machine-learning approaches to estimate nine leaf properties (chlorophyll, thickness, water content, nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur); and third, to investigate the usefulness of this spectral library for predicting external datasets …

Protease Inhibitor Asp Enhances Freezing Tolerance By Inhibiting Protein Degradation In Kumquat, Hua Yang, Ke-Wei Qiao, Jin-Jing Teng, Jia-Bei Chen, Ying-Li Zhong, Li-Qun Rao, Xing-Yao Xiong, Huang Li

Center for Plant Science Innovation: Faculty Publications

Cold acclimation is a complex biological process leading to the development of freezing tolerance in plants. In this study, we demonstrated that cold-induced expression of protease inhibitor FmASP in a Citrus-relative species kumquat [Fortunella margarita (Lour.) Swingle] contributes to its freezing tolerance by minimizing protein degradation. Firstly, we found that only cold-acclimated kumquat plants, despite extensive leaf cellular damage during freezing, were able to resume their normal growth upon stress relief. To dissect the impact of cold acclimation on this anti-freezing performance, we conducted protein abundance assays and quantitative proteomic analysis of kumquat leaves subjected to cold acclimation …

To Improve the Academy: A Journal of Educational Development

The demands of current instructional realities for moving to completely online formats have led to dramatic changes in the ways that centers for teaching and learning serve their communities. Pedagogical programs have been adapted, invented, and reimagined for online modalities. In this article, we share an approach borrowed from marketing—segmentation, targeting, and positioning (STP)—and describe three cases showing the application of STP in our center’s work with instructors. This approach has helped us clarify and target our pedagogical priorities, allowing us to make appropriate trade-offs to produce more focused educational development programming that better meets our audience’s needs, constraints, and …

Practical Guidelines For Development Of A University-Wide Faculty Mentorship Program Using A Multimodal Mentoring Network Model, Matthew G. Schwartz

To Improve the Academy: A Journal of Educational Development

Formal faculty mentorship programs are a practical and effective pathway to enable faculty success in teaching, scholarship, and service and to enhance faculty satisfaction. Although informal mentoring relationships benefit some faculty, formal faculty mentorship programs ensure equitable access to mentorship for female faculty and faculty from diverse, underrepresented backgrounds. Formal faculty mentorship programs can utilize a variety of structures, each with their benefits and drawbacks. This article recommends a multimodal mentoring network model to harness the benefits of traditional dyadic mentoring, multiple-mentor mentorship, peer and near-peer mentorship, and topic- and affinity-based group mentorship and to confer the flexibility, adaptability, and …

A Mixed Methods Study Of Faculty Experiences In A Course Design Institute, Carie N. Cardamone, Heather Dwyer

To Improve the Academy: A Journal of Educational Development

Remote teaching created a unique opportunity to study the experiences of faculty participating in a course design institute. Hundreds enrolled in our online institute, where technologies (e.g., Zoom, Canvas, Google Docs) facilitated interactions among participants and preserved their ideas and perspectives throughout the program. Using a grounded theory analysis approach attentive to the participants’ words, the authors uncovered participants’ experiences and their perspectives on the structures that shaped those experiences. The data ultimately revealed five themes (pedagogical knowledge, student perspective, community and connection, technology, and emotion) that relate to changes in participant attitudes, perceptions, and/or pedagogical approaches. Drawing on these …

Inter-Wythe Slip Design Criteria For Non-Composite Insulated Walls, Abdelrahman Awawdeh, Fray F. Pozo-Lora, Marc Maguire

Durham School of Architectural Engineering and Construction: Faculty Publications

Non-composite insulated wall connector design is governed by ICC-ES AC320. This standard works entirely in the loading domain, asking the engineer to prevent connector failure due to tension and shear loading. In this paper, the authors discuss additional criteria related to thermal loading and out-of-plane wind loading that create displacement demand in the non-composite connectors. Loads suitable for such analyses are not well defined. Loads are assumed and demonstrated herein and shown to cause significant displacement demand on connectors. Limited non-composite wythe connector testing is available, and some results are presented here. A comparison indicates that outright failure of non-composite …

Plasmon Enhanced Quantum Properties Of Single Photon Emitters With Hybrid Hexagonal Boron Nitride Silver Nanocube Systems, Mohammadjavad Dowran, Andrew Butler, Suvechhya Lamichhane, Adam Erickson, Ufuk Kilic, Sy_Hwang Liou, Christos Argyropoulos, A. Laraoui

Department of Mechanical and Materials Engineering: Faculty Publications

Hexagonal boron nitride (hBN) has emerged as a promising ultrathin host of single photon emitters (SPEs) with favorable quantum properties at room temperature, making it a highly desirable element for integrated quantum photonic networks. One major challenge of using these SPEs in such applications is their low quantum efficiency. Recent studies have reported an improvement in quantum efficiency by up to two orders of magnitude when integrating an ensemble of emitters such as boron vacancy defects in multilayered hBN flakes embedded within metallic nanocavities. However, these experiments have not been extended to SPEs and are mainly focused on multiphoton effects. …
