Fish scale gelatin/diatom biosilica composite hemostasis sponge with ultrafast dispersing and in situ gelation for hemorrhage control.

Rapid control of hemorrhage is vital in first-aid and surgery. As representative of emergency hemostatic materials, inorganic porous materials achieve rapid hemostasis through concentrating protein coagulation factors by water adsorption to accelerate the coagulation reaction process, however their efficacy is often limited by the insufficient contact of material with blood and the lack of blood clot strength. Herein, we report an ultrafast dispersing and in situ gelation sponge (SG/DB) based on anchoring interface effect for hemorrhage control using freeze drying method after mixing fish scale gel (SG) and tert-butyl alcohol (TBA) pre-crystallized diatom biosilica (DB).

Typical Case of Converter Smelting with High Cooling Ratio in Chinese Iron and Steel Enterprises: CO Emission Analysis.

In this study, the effects of using different scrap ratios in a converter on carbon emissions were analyzed based on life cycle assessment (LCA) theory, and the carbon emissions from the converter were evaluated with the use of coke and biochar as heating agents at high scrap ratios. In this industrial experiment, the CO emissions during the converter smelting process decreased with the increase in the scrap steel ratio. For every 1% increase in the scrap steel ratio, the carbon emissions during the steelmaking process decreased by 14.

The SUMO (Singly Unoccupied Molecular Orbital)-LUMO (Lowest Unoccupied Molecular Orbital) Inversion Radicals.

Herein, SUMO-LUMO inversion (SLI) radicals - were designed by the combination of the tris(2,4,6-trichlorophenyl)methyl (TTM) radical and pyridinium derivatives (electron-withdrawing groups) for the first time. The energy of the LUMO lies below that of the SUMO, which deviated from the Aufbau principle as an alternative electronic configuration beyond the well-established SOMO-HOMO inversed system. Thus, for SLI radicals, the injection of one extra electron preferred to occupy the LUMO rather than the SUMO, giving diradicals, one of which had been fully confirmed by single crystal analysis, VT-NMR and VT-EPR experiments, as well as DFT calculations.

Macrophages promote pre-metastatic niche formation of breast cancer through aryl hydrocarbon receptor activity.

Macrophages that acquire an immunosuppressive phenotype play a crucial role in establishing the pre-metastatic niche (PMN), which is essential for facilitating breast cancer metastasis to distant organs. Our study showed that increased activity of the aryl hydrocarbon receptor (AHR) in lung macrophages plays a crucial role in establishing the immunosuppressive PMN in breast cancer. Specifically, AHR activation led to high expression of PD-L1 on macrophages by directly binding to the promoter of Pdl1.

A multi-feature fusion graph attention network for decoding motor imagery intention in spinal cord injury patients.

Electroencephalogram (EEG) signals exhibit temporal-frequency-spatial multi-domain feature, and due to the nonplanar nature of the brain surface, the electrode distributions follow non-Euclidean topology. To fully resolve the EEG signals, this study proposes a temporal-frequency-spatial multi-domain feature fusion graph attention network (GAT) for motor imagery (MI) intention recognition in spinal cord injury (SCI) patients.The proposed model uses phase-locked value (PLV) to extract spatial phase connectivity information between EEG channels and continuous wavelet transform to extract valid EEG information in the time-frequency domain.
