Vitamin E does not Disturb Polyunsaturated Fatty Acid Lipid Domains

November 1, 2022
Author(s)
Mitchell DiPasquale, Michael H. Nguyen, Stuart R. Castillo, Isabelle J. Dib, Elizabeth Kelley, Drew Marquardt
The antioxidant function of vitamin E in biomembranes remains a prominent topic of discussion. As its limitations as an antioxidant persist and novel functions are discovered, our understanding of the role of vitamin E becomes increasingly enigmatic. As a

Bi 12 O 17 Cl 2 with a Sextuple Bi-O Layer Composed of Rock-Salt and Fluorite Units and its Structural Conversion through Fluorination to Enhance Photocatalytic Activity

Kirsanova, Richard Dronskowski, Hajime Suzuki, Chengchao Zhong, Cedric Tassel, Kohdai Ishida, Yosuke Matsuzaki, Craig Brown, Koji Fujita, Kotaro Fujii, Masatomo Yashima, Yoji Kobayashi, Akinori Saeki, Itaru Oikawa, Hitoshi Takamura, Ryu Abe, Hiroshi Kageyama, Tatiana E. Gorelik, Artem M. Abakumov
Layered bismuth oxyhalides with bilayered (Bi 2 O 2 ) fluorite slabs are promising visible-light photocatalysts because of the ability to control the valence band levels. Here we show that a structurally uncharacterized Bi 12 O 17 Cl 2 , which has been

Restricting a-Synuclein Transport into Mitochondria by Inhibition of a-Synuclein-VDAC Complexation as a Potential Therapeutic Target for Parkinson's Disease Treatment

Megha Rajendran, Maria Queralt-Martin, Philip A. Gurnev, William M. Rosencrans, Amandine Rovini, Daniel Jacobs, Kaitlin Abrantes, David Hoogerheide, Sergey M. Bezrukov, Tatiana Rostovtseva
Involvement of alpha-synuclein (αSyn) in Parkinson's disease (PD) is complicated and difficult to trace on cellular and molecular levels. Recently we established that αSyn can regulate mitochondrial function by voltage-activated complexation with the

Fabrication of Lithium Indolide and Derivates for Ion Conduction

Author(s)
Jintao Wang, Yang Yu, Anan Wu, Khai Chen Tan, Hui Wu, Teng He, Ping Chen
Alkali-ion batteries have been widely used nowadays. The development of solid-state electrolytes (SSEs) to replace the widely used organic liquid electrolytes could effectively solve the issue of combustion due to the formation of alkali metal dendrites

Energy Broadening of Neutron Depth Profiles by Thin Polyamide Films

Jamie Weaver, Anna Job, Kedar Manandhar, Ichiro Takeuchi, Robert Gregory Downing
A protective covering is often required for neutron depth profiling (NDP) measurements of sensitive materials (e.g., Li-ion batteries). Addition of this layer can increase NDP profile energy broadening and depth assignment uncertainty. This study evaluates

a-Synuclein Interaction with Lipid Bilayer Discs

α-Synuclein (aSyn) is a 140 residue long protein that is present in presynaptic termini of nerve cells. The protein is also pathologically associated with Parkinson's disease, where it has been found to self-assemble into long amyloid fibrils forming

Relative effects of polymer composition and sample preparation on glass dynamics

Modern design of common adhesives, composites and polymeric parts makes use of polymer glasses that are stiff enough to maintain their shape under a high stress while still maintaining a ductile behavior after the yield point. Typically, material

The Single Residue K12 Governs the Exceptional Voltage Sensitivity of Mitochondrial Voltage-Dependent Anion Channel Gating

The voltage-dependent anion channel (VDAC) is a β-barrel channel of the mitochondrial outer membrane (MOM) that passively transports ions, metabolites, polypeptides, and single-stranded DNA. VDAC responds to a transmembrane potential by transitioning to a

The Effect of Transverse Wavefront Width on Specular Neutron Reflection

Charles Majkrzak, Norman F. Berk, Brian B. Maranville, Joseph Dura, Terrence J. Jach
In the analysis of neutron scattering measurements of condensed matter structure, it normally suffices to treat the incident and scattered neutron beams as if composed of incoherent distributions of plane waves with wavevectors of different magnitudes and

Electrostatic Repulsion Slows Relaxations of Polyelectrolytes in Semidilute Solutions
