FGF20 promotes spinal cord injury repair by inhibiting the formation of necrotic corpuscle P-MLKL/P-RIP1/P-RIP3 in neurons.

The disruption of the local microenvironment subsequent to spinal cord injury (SCI) leads to a substantial loss of neurons in the affected region, which is a major contributing factor to impaired motor function recovery in patients. Fibroblast growth factor 20 (FGF20) is a neurotrophic factor that plays a crucial role in neuronal development and homeostasis. In this study, the recombinant human FGF20 (rhFGF20) was found to mitigate the process of necroptosis in a mouse model of SCI, thereby reducing neural functional deficits and promoting SCI repair.

State-to-State Time-Dependent Quantum Dynamics Studies of the Si(P) + OH(X Π) → OSi(X Σ) + H(S) Reaction Based on a New HOSi(XA') Potential Energy Surface.

Quantum and quasi-classical dynamics calculations were conducted for the reaction of Si with OH on the latest potential energy surface (PES), which is obtained by fitting tens of thousands of energy points by using the many-body expansion formula. To obtain an accurate PES, all energy points calculated with aug-cc-pVQZ and aug-cc-pV5Z basis sets were extrapolated to the complete basis set limit. The accuracy of our new PES was verified by comparing the topographic characteristics and contour maps of potential energy with other works.

6PPD, Not 6PPD-Quinone, Induced Serious Zebrafish Eye Damage by Disrupting the Thyroid Signaling Pathway.

N-(1,3-Dimethylbutyl)-'-phenyl-1,4-phenylenediamine (6PPD) and its oxidation product 6PPD-quinone (6PPDQ) showed different acute toxicities and bioaccumulation potencies in fish. In this study, we compared the thyroid disrupting effects of 6PPD and 6PPDQ through , , and assays. Interestingly, although 6PPD and 6PPDQ showed similar docking affinities with thyroid hormone receptor (TR) isoforms and GH3 cell inhibition effects, the thyroid signaling pathway, eye development, phototactic behaviors, and cell density in the retinal layer in the larval zebrafish were significantly affected only following 6PPD exposure.

An effective design strategy for thermally activated delayed fluorescence emitters with aggregation-induced emission to enable sky-blue OLEDs that achieve an EQE of nearly 30.

Pure organic thermally activated delayed fluorescence (TADF) materials hold great promise for efficient organic light-emitting diodes (OLEDs), yet developing high-performance blue TADF materials that integrate short delayed lifetime with aggregation-induced emission (AIE) properties remains a significant challenge. In this study, we developed three highly-efficient blue TADF emitters (32clCBP, 32clCXT and 32PclCXT) featuring AIE character by integrating rigid π-extended donors with different acceptors. Notably, the doped 32PclCXT film achieved an exceptionally high photoluminescence quantum efficiency of up to 99% and a short delayed lifetime of 1.
