28-Day Oral Chronic Toxicity Study of Arctigenin in Rats

open access: yesFrontiers in Pharmacology, 2018
Arctium lappa (burdock) is the most popular daily edible vegetable in China and Japan because of its general health tonic effects. Previous studies focused on the beneficial role of Arctigenin but neglected its potential side-effects and toxicities.

Josephson effect through magnetic skyrmion [PDF]

open access: yes, 2015
We discover that the multiple degrees of freedom associated with magnetic skyrmions: size, position, and chirality, can all be used to control the Josephson effect and 0-pi transitions occurring in superconductor/magnetic skyrmion/superconductor ...

Cu-Catalyzed Oxidative 3-Amination of Indoles via Formation of Indolyl(aryl)iodonium Imides Using o-Substituted (Diacetoxyiodo)arene as a High-Performance Hypervalent Iodine Compound

open access: yesMolecules, 2019
An oxidative 3-amination of indole derivatives using hypervalent iodine(III) and bissulfonimides, which proceeds via the formation of indolyl(aryl)iodonium imides, was developed.

The chain of chirality transfer in tellurium nanocrystals

open access: yesScience, 2021
What makes things twist? Crystallization and chirality have been entangled since Pasteur's observations on chiral tartaric acid crystals, yet there is still limited understanding of how chiral compounds form chiral crystal morphologies.

Switching magnon chirality in artificial ferrimagnet [PDF]

open access: yesNature Communications, 2021
Chirality, an intrinsic degree of freedom, has been barely exploited as the information carriers in data transmission, processing, computing, etc.

Remarkable functions of sn-3 hydroxy and phosphocholine groups in 1,2-diacyl-sn-glycerolipids to induce clockwise (+)-helicity around the 1,2-diacyl moiety: Evidence from conformation analysis by 1H NMR spectroscopy

open access: yesBeilstein Journal of Organic Chemistry, 2017
Cell-membrane glycerolipids exhibit a common structural backbone of asymmetric 1,2-diacyl-sn-glycerol bearing polar head groups in the sn-3 position. In this study, the possible effects of sn-3 head groups on the helical conformational property around ...

Buckling of chiral elastic rings spanned by fluid films

open access: yesVietnam Journal of Mechanics, 2022
We use variational method to examine buckling of chiral elastic rings spanned by fluid films. We find that the critical surface tension of the fluid film at which buckling occurs depends on the degree of chirality, regardless whether the ring possesses ...

Transferring Axial Molecular Chirality Through a Sequence of On-Surface Reactions

open access: yes, 2020
Fine management of chiral processes on solid surfaces has progressed over the years, yet still faces the need for the controlled and selective production of advanced chiral materials.

Cell Chirality Drives Left-Right Asymmetric Morphogenesis

open access: yesFrontiers in Cell and Developmental Biology, 2018
Most macromolecules found in cells are chiral, meaning that they cannot be superimposed onto their mirror image. However, cells themselves can also be chiral, a subject that has received little attention until very recently.
