Preliminary experience of endovascular treatment of acute mesenteric occlusion in stable patients with acute type A aortic dissection.

Background: Patients presenting with Stanford type A aortic dissection complicated by acute occlusion of the superior mesenteric artery (SMA) exhibit an exceedingly high mortality rate, even if emergency surgery for ascending aorta repair is performed. consequently, appropriate management of acute SMA occlusion arising from acute Stanford type A aortic dissection is crucial. This study aimed to evaluate the safety and efficacy of endovascular treatment of acute mesenteric occlusion first in stable patients with acute type A aortic dissection.

Mimic metalloenzymes with atomically dispersed Fe sites in covalent organic framework membranes for enhanced CO photoreduction.

The massive CO emissions from continuous increases in fossil fuel consumption have caused disastrous environmental and ecological crises. Covalent organic frameworks (COFs) hold the potential to convert CO and water into value-added chemicals and O to mitigate this crisis. However, their activity and selectivity are very low under conditions close to natural photosynthesis.

Transcriptome analysis revealed the new mechanism of the intra-myocardial injectable alginate-hydrogel in the treatment of ventricular function degradation.

Background: Myocardial infarction (MI) is one of the most lethal cardiovascular diseases. The loss of cardiomyocytes and the degradation of the extracellular matrix leads to high ventricular wall stress, which further drives the pathological thinning of the ventricular wall during MI. Injecting biomaterials to thicken the infarct ventricular wall provides mechanical support, thereby inhibiting the continued expansion of the heart.

Understanding the Positive Role of Ionic Liquids in CO Capture by Poly(ethylenimine).

CO capture technology is one of the most important technical methods for significantly mitigating CO emissions in a low-carbon context. The recent invention of mixed absorbents comprising poly(ethylenimine) (PEI) and ionic liquids (ILs) provides a novel strategy for efficiently capturing CO, and this has garnered widespread attention. However, the intermolecular interactions between the IL and other constituents during the CO absorption process remain unclear.

[Runoff Simulation and Its Response to Extreme Precipitation in the Yangtze River Basin].

Studies on runoff are crucial for the scientific allocation, utilization, and development of water resources and can provide an important basis for the prevention and control of flood and drought disaster, as well as water environmental pollution management. Affected by global warming, the frequency and intensity of extreme climate events, particularly extreme precipitation, have significantly changed in recent years, which can directly or indirectly impact runoff changes. In this study, we used the SWAT model to simulate the spatiotemporal variations in runoff in the Yangtze River Basin from 1965 to 2019 and analyzed the response of runoff to precipitation under extreme conditions.

DNMT3A governs tyrosine kinase inhibitors responses through IAPs and in a cell senescence-dependent manner in non-small cell lung cancer.

Patients with non-small cell lung cancer (NSCLC) treated with tyrosine kinase inhibitors (TKIs) inevitably exhibit drug resistance, which diminishes therapeutic effects. Nonetheless, the molecular mechanisms of TKI resistance in NSCLC remain obscure. In this study, data from clinical and TCGA databases revealed an increase in DNMT3A expression, which was correlated with a poor prognosis.

A solvent-free pyrolysis gas chromatography-mass spectrometry method was developed to simultaneously screen 33 restricted substances, comprising 7 phthalates, 15 bromine flame retardants, 4 phosphorus flame retardants, 4 ultraviolet stabilizers, and 3 bisphenols. The pyrolysis technique and temperatures affecting additive desorption were studied.

Ag Single Atoms Anchored on CeO with Interfacial Oxygen Vacancies for Efficient CO Electroreduction.

Ag single-atom catalysts (SACs) have great potential in selective electrocatalysis of the CO reduction reaction (CORR) to CO, while it is still a challenge to achieve high current density and high atom efficiency simultaneously. Here, we present a new and simple adsorption-reduction method to prepare Ag SACs supported on CeO (Ag/CeO). It is found that Ag single atoms are anchored on CeO through strong metal-support interaction (SMSI), and each Ag atom is accompanied with three interfacial oxygen vacancies.

Bismuth-Decorated Honeycomb-like Carbon Nanofibers: An Active Electrocatalyst for the Construction of a Sensitive Nitrite Sensor.

The existence of carcinogenic nitrites in food and the natural environment has attracted much attention. Therefore, it is still urgent and necessary to develop nitrite sensors with higher sensitivity and selectivity and expand their applications in daily life to protect human health and environmental safety. Herein, one-dimensional honeycomb-like carbon nanofibers (HCNFs) were synthesized with electrospun technology, and their specific structure enabled controlled growth and highly dispersed bismuth nanoparticles (Bi NPs) on their surface, which endowed the obtained Bi/HCNFs with excellent electrocatalytic activity towards nitrite oxidation.

Covalent organic frameworks (COFs) hold the potential in converting CO with water into value-added fuels and O to save the deteriorating ecological environment. However, reaching high yield and selectivity is a grand challenge under metal-, photosensitizer-, or sacrificial reagent-free conditions. Here, inspired by microstructures of natural leaves, we designed triazine-based COF membranes with the integration of steady light-harvesting sites, efficient catalytic center, and fast charge/mass transfer configuration to fabricate a novel artificial leaf for the first time.

Effects of Heating Treatment on Functional and Structural Properties of Liquid Whole Egg.

Liquid whole egg (LWE) products have many advantages such as convenient transportation, easy production and are safe. However, LWE has a short shelf life and high thermal sensitivity, so suitable heating treatment is the key to the production of LWE products. The aim of this study is to investigate the effects of heating treatments conditions (at 55-67 °C for 0-10 min) on the emulsification, foaming activity and rheological properties of LWE.

Designing covalent organic frameworks with Co-O atomic sites for efficient CO photoreduction.

Cobalt coordinated covalent organic frameworks have attracted increasing interest in the field of CO photoreduction to CO, owing to their high electron affinity and predesigned structures. However, achieving high conversion efficiency is challenging since most Co related coordination environments facilitate fast recombination of photogenerated electron-hole pairs. Here, we design two kinds of Co-COF catalysts with oxygen coordinated Co atoms and find that after tuning of coordination environment, the reported Co framework catalyst with Co-O sites exhibits a high CO production rate of 18000 µmol g h with selectivity as high as 95.

In recent years, light-responsive molecules have been incorporated in metal-organic frameworks (MOFs) to fabricate light-responsive intelligent devices, where reversible isomerization of the guest molecules in the nanopores is crucial. However, how to design a porous environment of MOFs to achieve a reversible isomerization remains unknown until now. In this work, donor-acceptor Stenhouse adducts (DASAs), a new kind of visible light responsive compound, were confined in the nanopores of different MOFs to study their isomerization upon visible-light irradiation/mild heating.
