Aflatoxin B (AFB), the most toxic and prevalent mycotoxin in food and feed, and its hydroxylated metabolite aflatoxin M (AFM), common in dairy products, pose serious health risks. Effective degradation of these toxins is thus a key goal in food safety. In this study, HNGD-Mq02 was isolated and assessed for its ability to degrade AFB and AFM.

Polyimides (PIs) with superior transparency, mechanical robustness, and thermal stability are essential for advanced applications such as flexible electronics, foldable displays, and aerospace components, but simultaneous optimization of these properties remains challenging. Here, we present a data-driven multiobjective optimization framework for systematic polyimide design, supported by high-quality data sets extracted with the assistance of large language models. Leveraging robust machine learning models validated by the experimental synthesis and evaluation of five PI films, our method precisely predicts material performance and effectively deciphers complex structure-property relationships influenced by charge transfer complexes.

Background: In dynamic contrast-enhanced T1-weighted imaging (DCE-T1WI) of breast lesions, type III time-intensity curves (TICs) are associated with malignant lesions, and type I TICs are associated with benign lesions, but the association of type II curves with the status of breast lesions remains controversial. This study aimed to analyze the semi-quantitative parameters derived from DCE-T1WI in patients with type II TIC breast lesions and to develop a nomogram for the benign/malignant classification of lesions with type II TICs.

Methods: Data of patients with type II TIC breast lesions were retrospectively collected.

The rice blast fungus Magnaporthe oryzae secretes a battery of effector proteins to facilitate host infection. Among these effectors, pathogenicity toward weeping lovegrass 2 (Pwl2) was originally identified as a host specificity determinant for the infection of weeping lovegrass (Eragrostis curvula) and is also recognized by the barley (Hordeum vulgare) Mla3 resistance protein. However, the biological activity of Pwl2 remains unknown.

Article Synopsis
  • Deoxynivalenol (DON) is a harmful contaminant in cereals that poses health risks to humans and animals, and existing detoxification methods are not effective in specifically targeting DON while maintaining nutrient levels.
  • Researchers identified a new enzyme, AKR11A2, from Bacillus velezensis that can effectively degrade DON, showing optimal activity at pH 9 and 40°C, and maintaining over 90% stability under high temperatures and alkaline conditions.
  • The enzyme successfully reduced DON levels in contaminated corn by 50.69% and produced a less toxic compound, 3-epi-DON, indicating its potential as a practical solution for improving food safety.

The effect of pesticide pollution on environmental microorganisms in soil has become the focus of widespread concern in society today. The response of earthworm gut and surrounding soil microbial functional diversity and enzyme activity to carbendazim (CBD) was studied in a soil-earthworm ecosystem amended with manure. In the experiment, CBD was added to the manured soil (MS).

Article Synopsis
  • * The presence of these mycotoxins in food and feed significantly impacts health and can hinder economic growth, leading to a focus on finding ways to remove multiple mycotoxins simultaneously rather than just one at a time.
  • * The review outlines various strategies for detoxifying mycotoxins and suggests stricter regulations on co-existing mycotoxins to address their cumulative health effects, particularly since some can act together to increase their carcinogenic risks.

Aflatoxin B is a notorious mycotoxin with mutagenicity and carcinogenicity, posing a serious hazard to human and animal health. In this study, an AFB-degrading dipeptidyl-peptidase III mining from HNGD-TM15 (ADPP III) with a molecular weight of 79 kDa was identified. ADPP III exhibited optimal activity toward AFB at 40 °C and pH 7.

  • Thin-bed soft rock significantly impacts tunnel stability, necessitating early detection for effective construction strategies.
  • Traditional seismic methods fall short in accurately identifying these thin beds, prompting the development of a new high-resolution seismic signal processing technique using a sequential convolutional neural network (SCNN).
  • This SCNN enhances seismic data accuracy, successfully applying the model to real-world seismic data and improving resolution to better detect and analyze thin-bed rock formations.

Many of the world's most devastating crop diseases are caused by fungal pathogens that elaborate specialized infection structures to invade plant tissue. Here, we present a quantitative mass-spectrometry-based phosphoproteomic analysis of infection-related development by the rice blast fungus Magnaporthe oryzae, which threatens global food security. We mapped 8,005 phosphosites on 2,062 fungal proteins following germination on a hydrophobic surface, revealing major re-wiring of phosphorylation-based signaling cascades during appressorium development.

Zearalenone (ZEN) is a widespread mycotoxin that causes serious damage to animal husbandry and poses a threat to human health. A screen of ZEN-degrading soil bacteria yielded YT-4, which yielded 80% ZEN degradation after 6 h and 95% after 36 h. The gene sequence encoding the degradative enzyme ZENY was mined from the genome of YT-4 and expressed in yeast.

Dielectric barrier discharge plasma (DBDP) displays strong against fungal spores, while its precise mechanism of spore inactivation remains inadequately understood. In this study, we applied morphological, in vivo and in vitro experiments, transcriptomics, and physicochemical detection to unveil the potential molecular pathways underlying the inactivation of Aspergillus flavus spores by DBDP. Our findings suggested that mycelium growth was inhibited as observed by SEM after 30 s treatment at 70 kV, meanwhile spore germination ceased and clustering occurred.

To reduce the application dosage of thiamethoxam (TMX), we investigated the deposition and dissipation patterns in a pepper-planted ecosystem under different planting modes across four regions in China, namely Hainan (HN), Zhejiang (ZJ), Anhui (AH) and Hebei (HB). This study focused on the deposition and dissipation of TMX at concentrations of 63.00, 47.

The rice blast fungus Magnaporthe oryzae uses a pressurized infection cell called an appressorium to drive a rigid penetration peg through the leaf cuticle. The vast internal pressure of an appressorium is very challenging to investigate, leaving our understanding of the cellular mechanics of plant infection incomplete. Here, using fluorescence lifetime imaging of a membrane-targeting molecular mechanoprobe, we quantify changes in membrane tension in M.

Historic coal gangue stacking probably brings heavy metals (HMs) into the surrounding agricultural soil, posing potential harm to human and environmental health. For better controlling and preventing agricultural soil HMs pollution, the screening of priority pollutants and identification of their pollution pathways are urgent in coal gangue stacking areas. Thus, this study selected a coal gangue stacking area in Chongqing, China as the research object and conducted the pollution evaluation, spatial distribution and source apportionment of the HMs (Cd, Cr, Ni, Cu, Zn, As, Pb and Hg) in surrounding agricultural soil.
