2020-Current year OA Pubs

BACKGROUND: Brain tumor formation and progression are dictated by cooperative interactions between neoplastic and non-neoplastic cells. This stromal dependence is nicely illustrated by tumors arising in the Neurofibromatosis type 1 (NF1) cancer predisposition syndrome, where children develop low-grade optic pathway gliomas (OPGs). Using several authenticated

METHODS: A combination of bulk and single-cell RNA mouse optic nerve sequencing, immunohistochemistry, T cell assays, and pharmacologic and antibody-mediated inhibition methods were used in these experiments.

RESULTS: We show that T cells and microglia are the main non-neoplastic immune cell populations in both murine and human LGGs. Moreover, we demonstrate that CD8

Srivastava, Victoria Padilla-Gainza, Manuel Peredo, Carlos Trevino De Leon, Bryan Hoke, Santosh K. Gupta, Karen Lozano

Mechanical Engineering Faculty Publications

Highlights

• Direct Rare Earth doping in PVDF Polymer to overcome powder limitation.

• PVDF Fiber with smooth and defect free texture designed by Forcespinning.

• Doping Enhances Beta fraction of PVDF without affecting thermal Stability.

• Efficient upconversion of NIR into visible light in PVDF:Yb3+,Er3+ fibrous mats.

Investing In Late-Life Brain Capital, Walter D Dawson, Eric J Lenze, Et Al.

2020-Current year OA Pubs

Within many societies and cultures around the world, older adults are too often undervalued and underappreciated. This exacerbates many key challenges that older adults may face. It also undermines the many positive aspects of late life that are of tremendous value at both an individual and societal level. We propose a new approach to elevate health and well-being in late life by optimizing late-life Brain Capital. This form of capital prioritizes brain skills and brain health in a brain economy, which the challenges and opportunities of the 21st-century demands. This approach incorporates investing in late-life Brain Capital, developing initiatives focused …

Applying Lessons From Safety-Ii Proof Of Concept In Line Operational Safety Audit To Aviation Maintenance, David R. Zubowski

Journal of Aviation/Aerospace Education & Research

Maintenance safety culture is a topic that continues to arise. There is much information in many different literature sources that discusses measuring, analyzing, and scrutinizing data to determine if a safety culture exists in an organization and how to improve it. Currently, aviation maintenance personnel are surveyed for their opinions on how safe their culture is. However, this may not be an adequate reflection of the safety culture or help maintenance personnel conduct their jobs. Typically, they are operating in an environment that has a central determination of what safety culture is. Other programs in other fields have attempted a …

Fluorescence Imaging Of Beta Cell Primary Cilia, Zipeng A Li, Jung Hoon Cho, Louis G Woodhams, Jing W Hughes

2020-Current year OA Pubs

Primary cilia are slender cell-surface organelles that project into the intercellular space. In pancreatic beta cells, primary cilia coordinate a variety of cell responses including GPCR signaling, calcium influx, and insulin secretion, along with likely many underappreciated roles in islet development and differentiation. To study cilia function in islet biology, direct visualization of primary cilia by microscopic methods is often a necessary first step. Ciliary abundance, distribution, and morphology are heterogeneous among islet cells and are best visualized by fluorescence microscopy, the tools for which are readily accessible to most researchers. Here we present a collection of fluorescence imaging methods …

One Vaccine To Counter Many Diseases? Modeling The Economics Of Oral Polio Vaccine Against Child Mortality And Covid-19, Angela Y Chang, Peter Aaby, Michael S Avidan, Christine S Benn, Stefano M Bertozzi, Lawrence Blatt, Konstantin Chumakov, Shabaana A Khader, Shyam Kottilil, Madhav Nekkar, Mihai G Netea, Annie Sparrow, Dean T Jamison

2020-Current year OA Pubs

INTRODUCTION: Recent reviews summarize evidence that some vaccines have heterologous or non-specific effects (NSE), potentially offering protection against multiple pathogens. Numerous economic evaluations examine vaccines' pathogen-specific effects, but less than a handful focus on NSE. This paper addresses that gap by reporting economic evaluations of the NSE of oral polio vaccine (OPV) against under-five mortality and COVID-19.

MATERIALS AND METHODS: We studied two settings: (1) reducing child mortality in a high-mortality setting (Guinea-Bissau) and (2) preventing COVID-19 in India. In the former, the intervention involves three annual campaigns in which children receive OPV incremental to routine immunization. In the latter, …
