Nucleophilic addition to α,β-unsaturated carbonyl compounds normally occurs at the carbonyl carbon or β-carbon. The direct α-nucleophilic addition at the α-carbon can hardly be achieved due to electronic mismatch. In this work, we report the nucleophilic addition of β-fluoroalkyl α-carbonyl carbocations that are prepared via -induced redox-neutral photocatalysis.

Histone acetylation and H3K4 trimethylation (H3K4me3) are associated with active transcription. However, how they cooperate to regulate transcription in plants remains largely unclear. Our study revealed that GLOBAL TRANSCRIPTION FACTOR GROUP E 4 (GTE4) binds to acetylated histones and forms a complex with the functionally redundant H3K4me3-binding EMSY-like proteins EML1 or EML2 (EML1/2) in Arabidopsis thaliana.

Conserved type B histone acetyltransferases are recognized for their role in acetylating newly synthesized histones in the cytoplasm of eukaryotes. However, their involvement in regulating chromatin within the nucleus remains unclear. Our study shows that the type B histone acetyltransferase HAG2 interacts with the histone chaperones MSI2, MSI3, and NASP, as well as the histones H3 and H4, forming a complex in both the cytoplasm and the nucleus.

Article Synopsis
  • The study focuses on creating bio-based composites using starch and wood fibers to address environmental issues linked to non-renewable materials, but these bio-composites are flammable due to their high carbon content.
  • To improve fire resistance, flame retardants like ammonium polyphosphate and calcium carbonate were added, resulting in two composite types (SWA-5 and SWA-10) that achieved high fire safety ratings and impressive limiting oxygen indexes.
  • SWA-10 showed a significant reduction in heat release and smoke production, while both composites demonstrated good mechanical properties, thermal insulation, and biodegradability, making them ideal for eco-friendly construction applications.

Proper control of inflammatory responses is essential for embryonic development, but the underlying mechanism is poorly understood. Here, we show that under physiological conditions, inactivation of ISG15, an inflammation amplifier, is associated with the interaction of Beclin 1 (Becn1), via its ECD domain, with STAT3 in the major fetal hematopoietic organ of mice. Conditional loss of Becn1 caused sequential dysfunction and exhaustion of fetal liver hematopoietic stem cells, leading to lethal inflammatory cell-biased hematopoiesis in the fetus.

We report the photocatalytic oxidation of α-carbonyl radicals of amides or esters to the corresponding α-carbonyl carbocations through super photoreductant CBZ6 induced redox-neutral photocatalysis. The α-carbonyl radicals are formed by the β-addition of alkyl radicals generated in situ by the photocatalytic fragmentation of N-hydroxyphthalimide esters to the α,β-unsaturated amides and esters. This method enables the α-nucleophilic addition of hydroxyl or alkoxyl radicals to amides and esters without any prefunctionalization.

Traumatic defects or non-union fractures presents a substantial challenge in the fields of tissue engineering and regenerative medicine. Although synthetic calcium phosphate-based biomaterials (CaPs) such as dibasic calcium phosphate anhydrate (DCPA) are commonly employed for bone repair, their inadequate cellular immune responses significantly impede sustained degradation and optimal osteogenesis. In this study, drawing inspiration from the key structure of an acidic non-collagenous protein-CaP complex (ANCPs-CaP) essential for natural bone formation, we prepared biomimetic mineralized dibasic calcium phosphate (MDCPA).

  • Identifying the seizure occurrence period (SOP) in EEG recordings is critical for accurate seizure diagnosis, but current systems mainly differentiate between ictal and interictal states, limiting their clinical use due to reliance on labeled data.
  • This study presents an unsupervised learning framework called 1D-CasCAE that analyzes EEG segments, focusing on learning patterns from non-seizure segments to improve detection of seizure (ictal) segments without needing labeled data.
  • Experimental results show that the 1D-CasCAE outperforms existing methods in detecting anomalies in EEG recordings, achieving high scores in sensitivity, specificity, and precision, making it a promising tool for clinical applications to reduce the need for manual EEG analysis by neurologists.*

The high water solubility and flammability of polyvinyl alcohol (PVA) limits its further widespread use in areas such as bioplastic and green packaging. In this study, double-crosslinked polyvinyl alcohol/starch bioplastics (named PDA) were fabricated using PVA, dialdehyde starch (DAS), and phytic acid (PA), resulting in a material with superior water resistance, flame retardancy, and excellent degradability. PA not only plays the role of catalyst for the chemical crosslinking but also as the physical crosslinker to form the intermolecular hydrogen bonds with PVA and DAS.
