SASH1 is a novel binding partner to disassemble Caskin1 tandem SAM homopolymer through heterogeneous SAM-SAM interaction.

Calcium/calmodulin-dependent serine protein kinase (CASK) interaction protein 1/2 (Caskin1/2) is essential neuronal synaptic scaffold protein in nervous system development. Knockouts of Caskin1/2 display severe deficits in novelty recognition and spatial memory. The tandem sterile alpha motif (SAM) domains of Caskin1/2, also conserved in their Drosophila homolog Ckn, are known to form homopolymers, yet their dynamic regulation mechanism remains unclear.

Frequency shift caused by a magnetic field and light intensity inhomogeneity in an optically detected clock.

We present a novel, to the best of our knowledge, frequency shift mechanism in the optically detected atomic clock. This frequency shift is analogous to the light shift that is associated with a detecting light power. However, this shift arises from the inhomogeneity of the magnetic field (C-field) and the detecting light intensity.

This study aims to investigate the association between serum vitamin D concentrations and mortality risk in critically ill patients diagnosed with AKI.

NPF and sNPF can regulate the feeding behaviour and affect the growth and antioxidant levels of the rice brown planthopper, Nilaparvata lugens.

Neuropeptide F (NPF) and short neuropeptide F (sNPF) are important neuropeptides and mainly affect feeding behaviour of insects. However, the regulation of insect feeding behaviour by NPF and sNPF appears to differ between species, and it is not clear how NPF and sNPF regulate the food intake of the brown planthopper (Nilaparvata lugens). Therefore, the functions of NPF and sNPF in regulating food intake and affecting the growth and antioxidant levels of N.

This study arm to elucidate the long-term consequences of OSA-related oxygen deprivation on central nervous system function.

Installing a Trigger to Upcycle High-Density Polyethylene.

Creating C═C bonds as "weak" sites in the stable C-C chains of polyethylene (PE) is an appealing strategy to promote sustainable development of the polyolefin industry. Compared to methods, such as dehydrogenation and postpolymerization modification, the copolymerization of ethylene (E) and butadiene (BD) should be a convenient and direct approach to introduce C═C bonds in PE, whereas it encounters problems in controlling the composition and regularity of the copolymer due to the mismatched activities and mechanisms between the two monomers. Herein, we report by employing the amidinate gadolinium complex, controllable E/BD copolymerization was achieved, where BD was incorporated in the uniformly discrete 1,4 mode.

Synthesis, characterization of chitosan/tripolyphosphate nanoparticles loaded with 4-chloro-2-methylphenoxyacetate sodium salt and its herbicidal activity against Bidens pilosa L.

Herbicides are widely used to control weeds in agriculture filed, however, the excessive use of the conventional formulation causes harmful side effects on the environment. To relieve this problem, natural polymer nanoparticles as herbicide carrier were rapidly developed and applied in recent years. In the present study, chitosan/tripolyphosphate (CS/TPP) nanoparticles were synthesized as nanocarrier to load herbicide 4-chloro-2-methylphenoxyacetate sodium salt (MCPA-Na).

Solvent-dependent chemoselective synthesis of different isoquinolinones mediated by the hypervalent iodine(III) reagent PISA.

Isoquinolinone is an important heterocyclic framework in natural products and biologically active molecules, and the efficient synthesis of this structural motif has received much attention in recent years. Herein, we report a (phenyliodonio)sulfamate (PISA)-mediated, solvent-dependent synthesis of different isoquinolinone derivatives. The method provides highly chemoselective access to 3- or 4-substituted isoquinolinone derivatives by reacting -alkenylbenzamide derivatives with PISA in either acetonitrile or wet hexafluoro-2-isopropanol.

Activating lattice oxygen in local amorphous S-modified NiFe-LDH ultrathin nanosheets toward superior alkaline/natural seawater oxygen evolution.

The admire activity, selective and corrosion resistance electrocatalysts for oxygen evolution reaction (OER) are the bottleneck restricting seawater electrolysis owing to the side reactions of chloride ions (Cl). Herein, we developed a local amorphous S-modified NiFe-LDH ultrathin nanosheets with large spacing on NiFe foam (la-S-NiFe-LDH/NFF) in-situ via the fast HO assisted etching-anion regulation, resulting in a superior OER catalytic activity for seawater electrolysis. Benefitting from the local amorphous architecture induced by S, enhanced the metal-oxygen covalency, triggered lattice oxygen activity, and reduced the desorption energy of O, the la-S-NiFe-LDH/NFF accelerated the OER progress via the lattice-oxygen-mediated (LOM) mechanism.

Salvianolic acid B improves diabetic skin wound repair through Pink1/Parkin-mediated mitophagy.

Diabetic skin wound is a disturbing and rapidly evolving clinical issue. Here, we investigated how salvianolic acid B (Sal B) affected the diabetic wound healing process. Following Sal B administration, histopathological damage was investigated by H&E and Masson staining, and CD34, apoptosis and mitophagy markers were measured by immunofluorescence, immunohistochemistry, and western blotting.

Citrate serves as a signal molecule to modulate carbon metabolism and iron homeostasis in Staphylococcus aureus.

Pathogenic bacteria's metabolic adaptation for survival and proliferation within hosts is a crucial aspect of bacterial pathogenesis. Here, we demonstrate that citrate, the first intermediate of the tricarboxylic acid (TCA) cycle, plays a key role as a regulator of gene expression in Staphylococcus aureus. We show that citrate activates the transcriptional regulator CcpE and thus modulates the expression of numerous genes involved in key cellular pathways such as central carbon metabolism, iron uptake and the synthesis and export of virulence factors.

We aimed to investigate the adjunctive impact of Baduanjin on exercise capacity and quality of life for HFmrEF/HFpEF.

Methods: Patients with HFmrEF/HFpEF were enrolled in this multicenter randomized clinical trial.

DNA encoded peptide library for SARS-CoV-2 3CL protease covalent inhibitor discovery and profiling.

Covalent protease inhibitors serve as valuable tools for modulating protease activity and are essential for investigating the functions of protease targets. These inhibitors typically consist of a recognition motif and a covalently reactive electrophile. Substrate peptides, featuring residues capable of fitting into the substrate pockets of proteases, undergo chemical modification at the carbonyl carbon of the P1 residue with an electrophile and have been widely applied in the development of covalent inhibitors.
