Several previous trials from Western population studies have showed that statins may help reduce blood pressure (BP). However, randomized clinical data is limited. Xuezhikang, a partially extract of red yeast rice, contains a family of naturally occurring statins, and has a marked impact on lipids, …

The capacity fading of layered lithium-rich oxide (Li 1.2 Mn 0.54 Ni 0.13 Co 0.13 O 2, LLO) cathodes greatly hinders their practical application in next generation lithium ion batteries.It has been demonstrated in this work that the slow capacity fading of a LLO/Li cell within 120 cycles is mainly caused by electrolyte oxidation and LLO phase transformation …

Background: As new biomarkers of coronary artery diseases (CAD) emerge via metabolomics, the underlying functional mechanisms remain to be elucidated. Functional metabolomics aims to translate metabolomics-derived biomarkers to disease mechanisms. Methods: A cohort of 2324 patients who underwent coronary angiography from 4 …

A pair of chiral aggregation-induced emission (AIE) enantiomers and their racemate exhibit not only distinctively different circularly polarized luminescence behaviors, but also completely opposite mechanoluminescence (ML) activities. The data from single crystal analysis identifies that the bright ML of the Recent Progress on Aggregation …

Herein, we report a heterogeneous single iron atom catalyst exhibiting excellent peroxidase, oxidase and catalase enzyme-like activities (defined as single atom enzymes, SAEs), exceeding those of Fe3O4 nanozymes by a factor of 40. Our findings open up a new family of artificial materials that mimic natural e

Interface engineering of electrocatalysts is a promising strategy to modulate their corresponding physicochemical properties. Compared with sulfides and selenides, the studies related to the interface engineering of the transition metal tellurides for oxygen evolution reaction (OER) remain scarce, regardless of their higher electrical conductivity …

In 2008 we published the first set of guidelines for standardizing research in autophagy. Since then, research on this topic has continued to accelerate, and many new scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Accordingly, it is impo …

Background: Systolic blood pressure of more than 185 mm Hg is a contraindication to thrombolytic treatment with intravenous alteplase in patients with acute ischaemic stroke, but the target systolic blood pressure for optimal outcome is uncertain. We assessed intensive blood pressure lowering compared with guideline-recommended …

Fine-tuning single-atom catalysts (SACs) to surpass their activity limit remains challenging at their atomic scale. Herein, we exploit p-type semiconducting character of SACs having a metal center coordinated to nitrogen donors (MeN x) and rectify their local charge density by an n-type semiconductor support.With iron phthalocyanine …

By utilizing C-shape bar resonators as the basic unit cells, simultaneous binary amplitude modulation and binary phase modulation in each pixel is realized. With polarization and frequency selective independent simultaneous control of amplitude and phase in every pixel, the proposed meta-hologram makes use of all four fundamental …

Optimizing active electronic states responding to catalysis is of paramount importance for developing high-activity catalysts because thermodynamics itself may not favor forming an optimal electronic state. Setting the monolayer transition metal dichalcogenide (TMD) ReS2 as a model for the hydrogen evolution reaction (HER), we …

The electrocatalyst shows state-of-the-art ORR performance with an admirable onset potential (E onset, 1.15 V vs. 1.05 V) and half-wave potential (E 1/2, 0.954 V vs. 0.842 V), outperforming those of the commercial Pt/C. The ORR test reveals that the performance of the (Fe,Co)/CNT is superior to most of the reported non-precious …
