[Research progress on in vitro effects of traditional Chinese medicine ingredients on liver UDP-glucuronosyltransferases].

UDP-glucuronosyltransferases(UGTs) are the main phase Ⅱ metabolizing enzymes in the human body, participating in the glucuronidation of various chemicals in the body. Traditional Chinese medicine(TCM) ingredients affect the activities of UGTs involved in drug metabolism, and the fluctuations in the blood concentrations of drugs metabolized by UGTs will lead to the risk of TCM-TCM or TCM-chemical drug interaction, which will cause drug safety problems and affect drug efficacy. Therefore, it is essential to explore the effect of TCM ingredients on the activities of UGTs.

Antibiotics-Free Steady Bioproduction of Valuable Chemicals from Organic Wastes by Engineered through Targeted Gene Integration.

Bioproduction of chemicals by using engineered bacteria is promising for a circular economy but challenged the instability of the introduced plasmid by conventional methods. Here, we developed a two-plasmid INTEGRET system to reliably integrate the targeted gene into the genome, making it a powerful strain for efficient and steady bioproduction without requiring antibiotic addition. The INTEGRET system allows for gene insertion at over 75% inserting efficiency and flexibly controllable gene dosages.

A review of multimodal deep learning methods for genomic-enabled prediction in plant breeding.

Deep learning methods have been applied when working to enhance the prediction accuracy of traditional statistical methods in the field of plant breeding. Although deep learning seems to be a promising approach for genomic prediction, it has proven to have some limitations, since its conventional methods fail to leverage all available information. Multimodal deep learning methods aim to improve the predictive power of their unimodal counterparts by introducing several modalities (sources) of input information.

PNMC: Four-dimensional conebeam CT reconstruction combining prior network and motion compensation.

Four-dimensional conebeam computed tomography (4D CBCT) is an efficient technique to overcome motion artifacts caused by organ motion during breathing. 4D CBCT reconstruction in a single scan usually divides projections into different groups of sparsely sampled data based on the respiratory phases. The reconstructed images within each group present poor image quality due to the limited number of projections.

On-demand synthesis of high-quality, blue-light-active ZnSe colloidal quantum wires.

Beyond the state-of-the-art Cd-containing quantum wires (QWs), heavy-metal-free semiconductor QWs, such as ZnSe, are of great interest for next-generation environmental-benign applications. Unfortunately, simultaneous, on-demand manipulation of their radial and axial sizes-that allows strong quantum confinement in the blue-light region-has so far been challenging. Here we present a two-step catalyzed growth strategy that enables independent, high-precision and wide-range controls over the diameter and length of ZnSe QWs.

A library of polytypic copper-based quaternary sulfide nanocrystals enables efficient solar-to-hydrogen conversion.

Designing polytypic homojunction is an efficient way to regulate photogenerated electrons and holes, thereafter bringing desired physical and chemical properties and being attractive photocatalysts for solar-to-hydrogen conversion. However, the high-yield and controllable synthesis of well-defined polytypes especially for multinary chalcogenide - the fundamental factor favoring highly efficient solar-to-hydrogen conversion - has yet to be achieved. Here, we report a general colloidal method to construct a library of polytypic copper-based quaternary sulfide nanocrystals, including CuZnSnS, CuCdSnS, CuCoSnS, CuMnSnS, CuFeSnS, CuInSnS and CuGaSnS, which can be synthesized by selective epitaxial growth of kesterite phase on wurtzite structure.

Biomolecular Insights into Extracellular Pollutant Reduction Pathways of Using a Base Editor System.

species are critically involved in elemental biogeochemical cycling and environmental bioremediation processes via extracellular electron transfer (EET), but the underlying biomolecular mechanisms remain elusive due to lack of effective analytical tools to explore into complicated EET networks. Here, a simple and highly efficient cytosine base editor was developed for engineering of the slow-growing (a doubling time of 5 h with acetate as the electron donor and fumarate as the electron acceptor). A single-plasmid cytosine base editor (pYYDT-BE) was constructed in by fusing cytosine deaminase, Cas9 nickase, and a uracil glycosylase inhibitor.

Reusing Sulfur-Poisoned Palladium Waste as a Highly Active, Nonradical Fenton-like Catalyst for Selective Degradation of Phenolic Pollutants.

Recycling of deactivated palladium (Pd)-based catalysts can not only lower the economic cost of their industrial use but also save the cost for waste disposal. Considering that the sulfur-poisoned Pd (PdS) with a strong Pd-S bond is difficult to regenerate, here, we propose a direct reuse of such waste materials as an efficient catalyst for decontamination via Fenton-like processes. Among the PdS materials with different poisoning degrees, PdS stood out as the most active catalyst for peroxymonosulfate activation, exhibiting pollutant-degradation performance rivaling the Pd and Co benchmarks.

Controlling pathogenic risks of water treatment biotechnologies at the source by genetic editing means.

Antimicrobial-resistant pathogens in the environment and wastewater treatment systems, many of which are also important pollutant degraders and are difficult to control by traditional disinfection approaches, have become an unprecedented treat to ecological security and human health. Here, we propose the adoption of genetic editing techniques as a highly targeted, efficient and simple tool to control the risks of environmental pathogens at the source. An 'all-in-one' plasmid system was constructed in Aeromonas hydrophila to accurately identify and selectively inactivate multiple key virulence factor genes and antibiotic resistance genes via base editing, enabling significantly suppressed bacterial virulence and resistance without impairing their normal phenotype and pollutant-degradation functions.
