Application of porous crystalline framework materials towards direct flue gas conversion.

The photocatalytic direct conversion of carbon dioxide (CO) from flue gas into high-value products is regarded as one of the most promising approaches to achieving carbon neutrality. Nevertheless, this direct conversion process encounters significant challenges, primarily due to practical limitations such as low CO concentrations and the presence of interfering substances. Porous crystalline framework materials exhibit considerable potential in flue gas conversion, attributed to their robust CO capture capabilities, well-defined and tunable structures, high specific surface areas, and plentiful catalytic sites.

Phytoalexin sakuranetin attenuates endocytosis and enhances resistance to rice blast.

Phytoalexin sakuranetin functions in resistance against rice blast. However, the mechanisms underlying the effects of sakuranetin remains elusive. Here, we report that rice lines expressing resistance (R) genes were found to contain high levels of sakuranetin, which correlates with attenuated endocytic trafficking of plasma membrane (PM) proteins.

Trinuclear Cu-based covalent organic framework: π-conjugated framework regulating electron delocalization to promote photoreduction CO.

Sunlight-driven CO reduction to value-added chemicals is an effective strategy to promote carbon recycling. The exploration of catalysts with efficient charge separation is crucially important for highly efficient CO photoreduction. In this work, the preparation of metal-cluster-based covalent organic framework (CuABD) integrated features from both metal organic frameworks (MOFs) and covalent organic frameworks (COFs) through the condensation of diamines and functionalized trinuclear copper clusters demonstrate a thoughtful design strategy.

Quality and Audience Engagement of Takotsubo Syndrome-Related Videos on TikTok: Content Analysis.

Background: The incidence of Takotsubo syndrome (TTS), also known as the broken heart syndrome or stress cardiomyopathy, is increasing worldwide. The understanding of its prognosis has been progressively evolving and currently appears to be poorer than previously thought, which has attracted the attention of researchers.

Distinct functional brain abnormalities in insomnia disorder and obstructive sleep apnea.

Insomnia disorder (ID) and obstructive sleep apnea (OSA) are the two most prevalent sleep disorders worldwide, but the pathological mechanism has not been fully understood. Functional neuroimaging findings indicated regional abnormal neural activities existed in both diseases, but the results were inconsistent. This meta-analysis aimed to explore concordant regional functional brain changes in ID and OSA, respectively.

Photocatalytic reduction of low-concentration CO by metal-organic frameworks.

Direct conversion of diluted CO to value-added chemical stocks and fuels with solar energy is an energy-saving approach to relieve global warming and realize a carbon-neutral cycle. The exploration of catalysts with both efficient CO adsorption and reduction ability is significant to achieving this goal. Metal-organic frameworks (MOFs) are emerging in the field of low-concentration CO reduction due to their highly tunable structure, high porosity, abundant active sites and excellent CO adsorption capacity.

Dynamic Interface with Enhanced Visible-Light Absorption and Electron Transfer for Direct Photoreduction of Flue Gas to Syngas.

The direct usage of CO in the flue gas to produce fuels or chemicals is of great significance from energy-saving and low-cost perspectives, yet it is still underexplored. Herein, we report the photoreduction of CO from the simulated industrial exhaust by synergistic catalysis of TEOA and a metal-free composite (COF1-g-CN) fabricated via covalently grafting COF1 with g-CN. The hydrogen bond interaction between TEOA and hydrazine units on COF1 is detected in diluted CO, which leads to significantly enhanced light absorption in the whole visible-light region.

Bimetallic Metal-Organic Framework-Derived Graphitic Carbon-Coated Small Co/VN Nanoparticles as Advanced Trifunctional Electrocatalysts.

The rational design and construction of multifunctional electrocatalysts with high activity, low cost, and outstanding stability are highly desirable for the development of renewable energy but are still a big challenge. Bimetallic catalysts are a kind of promising candidates, like the hybrids of Co and VN nanoparticles (Co/VN). However, the inevitable aggregation during the preparation and electrochemical process lowers their reactivity and durability.

Synergetic effect of H adsorption and ethylene functional groups of covalent organic frameworks on the CO photoreduction in aqueous solution.

We prepare a novel COF for CO2 photoreduction with 99.9% CO selectivity in aqueous solution without a cocatalyst. DFT shows that the preferential adsorption of H+ on the COF results in increased CO2 adsorption energy providing an anchoring site of CO2, and with the cooperation of an ethylene group, CO2 reduction is triggered.

The emerging role of circulating tumor cells in cancer management.

Circulating tumor cells (CTCs) are cells that are shed from the primary tumor and circulate in the blood, and their metastasis and formation of a secondary tumor are closely associated with cancer-related death. Therefore, regulating tumor metastasis through CTCs can be a novel strategy to fight cancer. It has been demonstrated that CTCs can reflect the profile of the primary tumor and provide valuable information about intratumoral heterogeneity and their evolution over time.

Rare combined variations of accessory left hepatic artery and accessory right hepatic artery: a case report and literature review.

Variations in the hepatic artery are commonly described in the literature, which is vital for the success procedure of all hepatobiliary surgery. Usually a variation occurs in either the accessory right hepatic artery (aRHA) or the accessory left hepatic artery (aLHA). However, we report an extremely rare case where the variation occurs in both simultaneously.

Circular RNAs: A novel target among non‑coding RNAs with potential roles in malignant tumors (Review).

Circular RNAs (circRNAs) are a class of non‑coding RNAs that are generated via alternative back‑splicing, which connects the terminal 5' and 3'ends. Due to their unique loop structure, circRNAs are resistant to ribonucleases and more stable than linear RNAs. In vivo, they are usually highly conserved and stably expressed in tissue/developmental‑stage‑specific manners.

An application of the driver behavior questionnaire to Chinese carless young drivers.

Objective: Carless young drivers refers to those drivers aged between 18 and 25 years who have a driver's license but seldom have opportunities to practice their driving skills because they do not have their own cars. Due to China's lower private car ownership, many young drivers turn into carless young drivers after licensure, and the safety issue associated with them has become a matter of great concern in China. Because few studies have examined the driving behaviors of these drivers, this study aims to utilize the Driver Behavior Questionnaire (DBQ) to investigate the self-reported driving behaviors of Chinese carless young drivers.
