Background: Angelicae Dahuricae Radix (ADR) is used as both a traditional Chinese medicine and a food ingredient in China and East Asian countries. ADR is generally sun-dried post-harvest but is sometimes sulfur-fumigated to prevent decay and rot. Although there are some studies on the effect of sulfur fumigation on ADR, they are not comprehensive.

Risk assessment of water inrush from coal floor based on enhanced samples with class distribution.

In the risk assessment of water inrush from coal floors, the amount of measured data obtained through on-site testing is small and random, which limits the prediction accuracy and generalizability of a model based on measured data. Using the distribution characteristics of the measured data and mega-trend diffusion theory, we propose a virtual sample enhancement method based on class distribution mega-trend diffusion technology (CDMTD) and introduce constraints on the class distribution of influencing factors. This method was used to generate virtual samples and enhance the measured database.

Ecofriendly and biocompatible biochars derived from waste-branches for direct and efficient solid-phase extraction of benzodiazepines in crude urine sample prior to LC-MS/MS.

Biochars (BCs) derived from waste-branches of apple tree, grape tree, and oak were developed for direct solid-phase extraction (SPE) of five benzodiazepines (BZDs) in crude urine samples prior to liquid chromatography-tandem mass spectrometry (LC-MS/MS) determination. Scanning electron microscopy, elemental analyzer, X-ray diffractometry, N adsorption/desorption experiments, and Fourier transform infrared spectrometry characterizations revealed the existence of their mesoporous structure and numerous oxygen-containing functional groups. The obtained BCs not only possessed high affinity towards BZDs via π-π and hydrogen bond interactions, but also afforded the great biocompatibility of excluding interfering components from undiluted urine samples when using SPE adsorbents.

Amyotrophic Lateral Sclerosis and Parkinson's Disease: Brain Tissue Transcriptome Analysis Reveals Interactions.

This study utilises amyotrophic lateral sclerosis (ALS) and Parkinson's disease (PD) human brain samples from the GEO database and employs differential expression gene (DEG) analysis to identify genes that are pivotal in both neurodegenerative diseases. Through in depth GO and KEGG enrichment analyses, we elucidated the biological functions and potential pathways associated with these DEGs. Furthermore, by constructing protein‒protein interaction networks, we highlight the significance of shared DEGs in both cellular physiology and disease contexts.

PO Tetrahedron Assisted Chelate Engineering for 10.67%-Efficient Antimony Selenosulfide Solar Cells.

Anisotropic carrier transport and deep-level defect of antimony selenosulfide (Sb(S,Se)) absorber are two vital auses restraining the photovoltaic performance of this emerging thin-film solar cell. Herein, chelate engineering is proposed to prepare high-quality Sb(S,Se) film based on hydrothermal deposition approach, which realizes desirable carrier transport and passivated defects by using tetrahedral PO ion in dibasic sodium phosphate (NaHPO, DSP). The PO Lewis structure, on one hand in the form of [(SbO)(PO)] chelate, can adsorb on the polar planes of cadmium sulfide (CdS) layer, promoting the heterogeneous nucleation, and on the other hand, the tetrahedral PO inhibits horizontal growth of (SbS(e)) ribbons due to size effects, thus achieving desirable [hk1] orientation.

Overlooked risks of photoaging of nitrogenous microplastics with natural organic matter in water: Augmenting the formation of nitrogenous disinfection by-products.

In aqueous environments, microplastics (MPs) undergo photoaging, releasing dissolved organic matter (DOM). Disinfection byproducts (DBPs) formation from natural organic matter (NOM) phototransformation has been reported. However, the impact of NOM on the photoaging of MPs (especially nitrogen-containing MPs) and subsequent nitrogenous DBPs (N-DBPs) formation remains unknown.

Simplified biomimetic peptide-based vehicle for enhanced tumor penetration and rapid enzyme-induced drug release.

Various nanodrug vehicles were well-designed with complicated functions for tumor therapy. However, the unsatisfactory tumor delivery efficiency and uncertain off-target release became the stumbling block of the nanodrugs on the way to the clinic. Inspired by efficient tumor targeting ability of albumin, we reported a simplified biomimetic peptide-based vehicle synthesized by copolymerizing L-glutamyl-L-lysine unit (EK dimer, an intrinsic surface peptide pair from albumin) with L-phenylalanine (F) to encapsulate doxorubicin (Dox).

ZDHHC3-LYPLA1 regulates PRRSV-2 replication through reversible palmitoylation.

Porcine reproductive and respiratory syndrome virus (PRRSV) is a highly contagious swine pathogen, causing respiratory problems in piglets and reproductive failure in sows. Palmitoylation, catalyzed by zinc finger Asp-His-His-Cys (ZDHHC) domain-containing palmitoyl acyltransferases, plays intricate roles in virus infection. However, whether palmitoylation regulates PRRSV replication is incompletely understood.

Phthalocyanine nickel enhanced composite solid-state electrolytes with homogenous and fast Li-ion conduction for high-voltage Li-metal batteries.

Herein, a novel composite solid-state polymer electrolytes (CSEs) was regulated by introducing CoNi-MOF (Metal-organic framework) @NiPc (Nickel phthalocyanine) nanofiller (CMN) into PEO (polyethylene oxide) matrix. In this novel system, the NiPc uniformly wrapped around the surface of MOF through hydrogen bond bridging, avoiding the agglomeration of the MOF particles. The chemisorption between Ni in NiPc and the O atoms in the bis(triffuoromethanesulfonyl)imide anion (TFSI) restricted the mobility of the anions within the CSEs, which improved the release of Li ions from the NiPcLi.
