Dynamics of motor network overactivation after striatocapsular stroke
BACKGROUND AND PURPOSE: Although excessive brain activation during affected hand motion after stroke is well documented, its time course has been rarely studied, and when studied, this has either been with passive movement or...
Plant defense signals
Plant viruses face an array of host defenses. Well-studied responses that protect against viruses include effector-triggered immunity, induced resistance (such as systemic acquired resistance mediated by salicylic acid), and RNA...
First Report of Cucumber mosaic virus Infecting Pimpinella brachycarpa in Korea
Pimpinella brachycarpa (family Apiaceae) is an edible green, leafy vegetable frequently consumed in Korea. The plant species is commonly used to prepare Namul, a seasoned raw vegetable dish. Recently, we reported an isolate of...
Linking particle properties to dense suspension extrusion flow characteristics using discrete element simulations
Extrusion is a widely used process for forming suspensions and pastes into designed shapes, and is central to the manufacture of many products. In this article, the extrusion through a square-entry die of non-Brownian spheres...
Enabling building digital twin
Abstract
The emergence of the digital twin concept can potentially change the way people manage built assets thoroughly. This is because the semantics-based model and linked data...
Respiratory Complex I in Bos taurus and Paracoccus denitrificans Pumps Four Protons across the Membrane for Every NADH Oxidized.
Respiratory complex I couples electron transfer between NADH and ubiquinone to proton translocation across an energy-transducing membrane to support the proton-motive force that drives ATP synthesis. The proton-pumping...

The evolution of intracranial aneurysm treatment techniques and future directions.
Keng Siang Lee, John JY Zhang, Vincent Nguyen, Julian Han, Jeremiah N Johnson, Ramez Kirollos, Mario Teo
Feb 09, 2022
Treatment techniques and management guidelines for intracranial aneurysms (IAs) have been continually developing and this rapid development has altered treatment decision-making for clinicians. IAs are treated in one of two...
Conformational plasticity of ligand-bound and ternary GPCR complexes studied by 19F NMR of the β1-adrenergic receptor.

Using Hyperfine Electron Paramagnetic Resonance Spectroscopy to Define the Proton-Coupled Electron Transfer Reaction at Fe-S Cluster N2 in Respiratory Complex I.
Nolwenn Le Breton, John J Wright, Andrew JY Jones, Enrico Salvadori, Hannah R Bridges, Judy Hirst, Maxie M Roessler
Jun 04, 2018
Energy-transducing respiratory complex I (NADH:ubiquinone oxidoreductase) is one of the largest and most complicated enzymes in mammalian cells. Here, we used hyperfine electron paramagnetic resonance (EPR) spectroscopic...

A systematic review and meta-analysis of the association between cyproterone acetate and intracranial meningiomas.
Keng Siang Lee, John JY Zhang, Ramez Kirollos, Thomas Santarius, Vincent Diong Weng Nga, Tseng Tsai Yeo
Feb 04, 2022
The influence of exposure to hormonal treatments, particularly cyproterone acetate (CPA), has been posited to contribute to the growth of meningiomas. Given the widespread use of CPA, this systematic review and meta-analysis...

A conserved arginine residue is critical for stabilizing the N2 FeS cluster in mitochondrial complex I.
Mikhail A Hameedi, Daniel N Grba, Katherine H Richardson, Andrew JY Jones, Wei Song, Maxie M Roessler, John J Wright, Judy Hirst
May 17, 2021
Respiratory complex I (NADH:ubiquinone oxidoreductase), the first enzyme of the electron-transport chain, captures the free energy released by NADH oxidation and ubiquinone reduction to translocate protons across an...
Long-term experimental drought alters floral scent and pollinator visits in a Mediterranean plant community despite overall limited impacts on plant phenotype and reproduction
CC Jaworski, B Geslin, M Zakardjian, C Lecareux, P Caillault, G Nève, JY Meunier, S Dupouyet, ACT Sweeney, OT Lewis, LV Dicks, C Fernandez
Aug 17, 2022
Abstract: Pollinators are declining globally, with climate change implicated as an important driver. Climate change can induce phenological shifts and reduce floral resources for pollinators, but little is known about its...
An ALMA 1.3 millimeter Search for Debris Disks around Solar-type Stars in the Pleiades
Abstract
Millimeter emission from debris disks around stars of different ages provides constraints on the collisional evolution of planetesimals. We present ALMA 1.3 millimeter...
Alcohol intake and risk of colorectal cancer
