A d-electron Deficient Pd Trimer for Exceptional Pyridine Hydrogenation Activity and Selectivity.

The selective hydrogenation of pyridines containing reducible groups such as 2-phenylpyridine typically has low yields due to strong nitrogen coordination with the metal as well as non-selective and over-hydrogenation. We report the synthesis of a novel Pd trimer catalyst through confined growth on an ordered mesoporous carrier, characterized by a 0.42 d-electron deficiency to address this challenge.

PwP: Permutating with Probability for Efficient Group Selection in VR.

Group selection in virtual reality is an important means of multi-object selection, which allows users to quickly group multiple objects and can significantly improve the operation efficiency of multiple types of objects. In this paper, we propose a group selection method based on multiple rounds of probability permutation, in which the efficiency of group selection is substantially improved by making the object layout of the next round easier to be batch-selected through interactive selection, object grouping probability computation, and position rearrangement in each round of the selection process. We conducted ablation experiments to determine the algorithm coefficients and validate the effectiveness of the algorithm.

WTAP-mediated mA methylation of PHF19 facilitates cell cycle progression by remodeling the accessible chromatin landscape in t(8;21) AML.

Wilms' tumor 1-associated protein (WTAP) is a key N6-methyladenosine (mA) methyltransferase that is upregulated in t(8;21) acute myeloid leukemia (AML) under hypoxia inducible factor 1α-mediated transcriptional activation, promoting leukemogenesis through transcriptome-wide mA modifications. However, the specific substrates and intrinsic regulatory mechanisms of WTAP are not well understood. Here, we provide evidence that PHD finger protein 19 (PHF19) overexpression is regulated by WTAP-mediated mA modification and promotes cell cycle progression by altering chromatin accessibility.

Low-dose tire wear chemical 6PPD-Q exposure elicit fatty liver via promoting fatty acid biosynthesis in ICR mice.

N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine-quinone (6PPD-Q) as a major metabolite of tire wear chemical 6PPD has been demonstrated to be an emerging burden of exposure in human populations, via contamination from drinking water, air particulate matter and food sources. Whilst increasing attention has been moved toward its adverse effect, the potential hepatotoxicity of 6PPD-Q in mammals at realistic dose remains unknown. Here, the toxic effects of 6PPD-Q at environmentally relevant dose on the liver of adult mice and its underlying mechanism were investigated through an integrative approach combining transcriptomic and lipidomic analyses.
