Association of higher triglyceride-glucose index and triglyceride-to-high-density lipoprotein cholesterol ratio with early neurological deterioration after thrombolysis in acute ischemic stroke patients.

Background: Insulin resistance (IR) can predict the prognosis of patients suffering from cerebrovascular disorders. The triglyceride-glucose (TyG) index and triglyceride-to-high-density lipoprotein cholesterol (TG/HDL-C) ratio have been confirmed to be easy and reliable indicators of IR. However, the relationships between the TyG index or TG/HDL-C ratio and early neurological deterioration (END) after thrombolysis in patients with acute ischemic stroke (AIS) are uncertain.

Tailoring mSiO-SmCo nanoplatforms for magnetic/photothermal effect-induced hyperthermia therapy.

Hyperthermia therapy is a hotspot because of its minimally invasive treatment process and strong targeting effect. Herein, a synergistic magnetic and photothermal therapeutic nanoplatform is rationally constructed. The well-dispersive mSiO-SmCo nanoparticles (NPs) were synthesized through a one-step procedure with the regulated theoretical molar ratio of Sm/Co among 1:1, 1:2, and 1:4 for controlling the dispersion and magnetism properties of SmCo NPs growth in the pore structure of mesoporous SiO (mSiO), where mSiO with diverse porous structures and high specific surface areas serving for locating the permanent magnetic SmCo NPs.

Boosting CO Hydrogenation to Formate over Edge-Sulfur Vacancies of Molybdenum Disulfide.

Synthesis of formate from hydrogenation of carbon dioxide (CO ) is an atom-economic reaction but is confronted with challenges in developing high-performance non-precious metal catalysts for application of the process. Herein, we report a highly durable edge-rich molybdenum disulfide (MoS ) catalyst for CO hydrogenation to formate at 200 °C, which delivers a high selectivity of over 99 % with a superior turnover frequency of 780.7 h surpassing those of previously reported non-precious metal catalysts.

A Study on Relationship of Hounsfield Units Value on Non-contrast Computer Tomography and Recanalization of Intravenous Thrombolysis.

Objective: The objective of this study is to determine whether the administration of intravenous alteplase would be beneficial or futile to patients with acute ischemic stroke caused by large vessel occlusion (LVO) before endovascular treatment (EVT) and determine the relationship between Hounsfield units (HU) in non-contrast computed tomography (NCCT) and recanalization by alteplase.

Methods: We performed a retrospective analysis of patients with acute ischemic stroke caused by LVO who received intravenous thrombolysis (IVT) or followed by EVT at our center during November 2016 and October 2020. The clinical characteristics and imaging features of patients who achieved recanalization after IVT, and those who did not, were compared.

A new rapid screening program based on risk scores for COVID-19 patients.

We aimed at establishing a new COVID-19 risk scores, serving as a guide for rapidly screening the COVID-19 patients in order to reduce the risk of COVID-19 hospital-related transmission. As the COVID-19 disease is breaking out across the world, hospital-related transmission is one of the main factors accountable for the spread of COVID-19. For COVID-19 prevention it is urgent to establish a fast and efficient screening strategy for the COVID-19 patients.

Synergistic ligand effect for the construction of titanium-oxo clusters with planar chirality and high solution stability.

A synergistic effect between dimethylglyoxime (to stabilize the Ti-O ribbon) and nonlinear dicarboxylate ligands (to bend the Ti-O ribbon) has been developed to form a series of planar chiral titanium-oxo clusters with high solution stability. The charality of the obtained clusters has been studied by X-ray structural and CD spectroscopy analysis.

Ligand-directed assembly engineering of trapezoidal {Ti} building blocks stabilized by dimethylglyoxime.

Through ligand-directed assembly of trapezoidal {Ti} building blocks stabilized by dimethylglyoxime, eight titanium-oxo molecular clusters with a sandwich or square planar type structures were successfully constructed, including the first success on the combination of porphyrin and titanium-oxo clusters.

Double defects modified carbon nitride nanosheets with enhanced photocatalytic hydrogen evolution.

Graphitic carbon nitride (g-C3N4) is an actively investigated metal-free photocatalyst for solar energy conversion. However, primary g-C3N4 usually exhibits limited utilization of visible light and fast combination of photoexcited charge carriers, resulting in low photocatalytic H2 evolution activity. Defect-modified g-C3N4 shows much enhanced photocatalytic H2 evolution activity owing to extended light absorption as well as efficient charge separation and transfer.

Integrating the g-CN Nanosheet with B-H Bonding Decorated Metal-Organic Framework for CO Activation and Photoreduction.

BIF-20, a zeolite-like porous boron imidazolate framework with high density of exposed B-H bonding, is combined with graphitic carbon nitride (g-CN) nanosheets via a facile electrostatic self-assembly approach under room temperature, forming an elegant composite BIF-20@g-CN nanosheet. The as-constructed composite preferably captures CO and further photoreduces CO in high efficiency. The photogenerated excitations from the carbon nitride nanosheet can directionally migrate to B-H bonding, which effectively suppresses electron-hole pair recombination and thus greatly improves the photocatalytic ability.

Interface engineered in situ anchoring of CoS nanoparticles into a multiple doped carbon matrix: highly efficient zinc-air batteries.

Interface modification is an effective and promising route for developing functional electrocatalysts. However, researchers have not created a reliable method to optimize the interfaces of components existing in electrocatalysts, although it is very crucial for the technological development of high-performance electrodes. Here, we develop a strategy aiming at the in situ anchorage of CoS nanoparticles into a nitrogen (N), sulfur (S) co-implanted three-dimensional carbon matrix (CoS@NSCM) as a highly active and durable nonprecious metal electrocatalyst for the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) in alkaline medium.

An anionic Cd(ii) boron imidazolate framework with reversible structural transformation and biomolecular sensing properties.

An anionic Cd(ii) boron imidazolate framework (BIF-82) with gra topology has been synthesized by the targeted assembly of Cd(ii), the 1,3,5-benzenetricarboxylate ligand and the tetradentate boron imidazolate ligand, which shows reversible structural transformation, and it can encapsulate Ag nanoparticles into its structure for further sensing of cysteine.

Selectivity of CO2 via pore space partition in zeolitic boron imidazolate frameworks.

Reported here is a versatile method capable of generating pore space partition in zeolitic boron imidazolate frameworks (BIFs), which is based on the coexistence of presynthesized boron imidazolate complexes and charge balancing carboxylate ligands. Using this method, boron imidazolate complexes are used to form zeolitic nets, while the carboxylate serves to partition large channel spaces into multiple domains. The generality of this method is shown by two distinct boron imidazolate frameworks mimicking GIS (BIF-41) and ABW (BIF-42) zeotype topologies.

A cuttlebone-derived matrix substrate for hydrogen peroxide/glucose detection.

A simple biosensor for hydrogen peroxide (H(2)O(2)) and glucose was fabricated by incorporating gold nanoparticles (GNPs) onto a cuttlebone-derived matrix substrate (CDMS). Such a three-dimensional chamber-like structure naturally bears abundant amino groups for the direct immobilization of GNPs without a series of modifications. And preferably, the framework endows CDMS with a very high surface area for the attachment of GNPs, resulting in effective optical signal transduction and improved sensitivity of the detection system.

Cuttlebone-derived organic matrix as a scaffold for assembly of silver nanoparticles and application of the composite films in surface-enhanced Raman scattering.

Biologically derived materials provide a rich variety of approaches toward new functional materials because of their fascinating structures and environment-friendly features, which is currently a topic of research interest. In this paper, we show that the cuttlebone-derived organic matrix (CDOM) is an excellent scaffold for the one-step synthesis and assembly of silver nanoparticles (AgNPs), which can be further used as substrate for surface-enhanced Raman scattering (SERS). Formation of AgNPs-CDOM composite was accomplished by the reaction of CDOM with AgNO(3) and NH(3).
