The Epigenetic Regulation of Agronomic Traits and Environmental Adaptability in Brassicas.

As essential sources of vegetables, oilseeds, and forage, Brassica crops exhibit complex epigenetic regulation mechanisms involving histone modifications, DNA modifications, RNA modifications, noncoding RNAs, and chromatin remodelling. The agronomic traits and environmental adaptability of crops are regulated by both genetic and epigenetic mechanisms, while epigenetic variation can affect plant phenotypes without changing gene sequences. Furthermore, the impact of epigenetic modifications on plant phenotype has accelerated the crop breeding process.

Injectable and tissue adhesive chrysomycin A-laden chitosan hydrogel depot for MRSA-infected wound healing and tumor recurrence prevention.

Tumor surgery often leads to tumor residue, tissue defects, and drug-resistant bacterial infections, resulting in high recurrence rates and chronic wounds. In this study, an injectable hydrogel was synthesized using glycidyl trimethyl ammonium chloride-chitosan (GCh) and formylbenzoic acid-modified chrysomycin A (CA)-loaded F127 micelles (F127FA-CA). The formation of the hydrogel is achieved through Schiff base conjugation, which occurs between the amino groups present in GCh and the aldehyde groups located on the micelle surfaces.

Submicron metal-bearing aerosols from an industrial hub of the North China Plain.

Particulate matter emitted from heavy industries is a major source of atmospheric metals in the North China Plain (NCP). In this study, submicron particles (0.1-1.

ZnO dual-functional template-assisted construction of hierarchical porous hard carbon anode for high-rate sodium storage.

Hard carbon has emerged as the most widely studied and commercialized anode material for sodium-ion batteries (SIBs). However, improving the charge transfer kinetics within the plateau potential range of the hard carbon anode is crucial for the development of fast-charging SIBs. In this study, we prepared a novel composite material, ZAPA-1300, by uniformly mixing starch, asphalt, and zinc oxide (ZnO), followed by a two-step treatment process.

Differential Effects of Wildfire Smoke Pm Exposure on Respiratory Disease Emergency Department Visits in the Western United States.

Background: Wildfires significantly affect air quality in the Western United States. Although prior research has linked wildfire smoke PM to respiratory health outcomes, these studies typically have limited geographic and temporal coverage, lacking evidence from multiple states over extended periods.

Methods: We obtained data on over 6 million emergency department (ED) visits for respiratory diseases, including asthma, chronic obstructive pulmonary disease (COPD), upper respiratory infections (URI), and bronchitis, from five states in the Western US during 2007-2018.
