α-Cyclodextrin mediated 3D printed ceramic/polymer composite scaffolds for immunomodulation and osteogenesis in bone defect repair.

Bone tissue engineering scaffolds for bone defect treatment face numerous challenges, including mechanical mismatches and the lack of immune microenvironment modulation, often leading to implant failure. In this study, an innovative drug-loaded bioinspired ceramic/polymer composite scaffold was designed and fabricated using extrusion-based 3D printing technology, incorporating α-cyclodextrin (αCD) in a novel approach to improve interfacial compatibility and drug-loading efficiency. Hydroxyapatite (HA), the main component of natural bone, was employed as the inorganic phase to mimic the mineral structure of bone tissue.

Lignin Dissolution and Direct Ultrasmall-Lignin-Nanoparticle Formation in Acidic and Alkaline Deep Eutectic Solvents: A Molecular-Level Insight.

Although deep eutectic solvents (DESs) have demonstrated significant potential in lignin processing, their influence on molecular stacking and conformational evolution during lignin dissolution and nanoparticle formation remains insufficiently understood. Here, we develop a green, straightforward, and single-step approach to produce self-assembled lignin nanoparticles (LNPs). The LNPs obtained using the acidic DES method exhibited a great size reduction, with an average size approximately one-ninth of that produced by conventional solvent-exchange methods.

N-glycosylation of SnRK2s affects NADPH maintenance in peroxisomes during prolonged ABA signalling.

Unfavourable conditions, such as prolonged drought and high salinity, pose a threat to the survival and agricultural yield of plants. The phytohormone ABA plays a key role in the regulation of plant stress adaptation and is often maintained at high levels for extended periods. While much is known about ABA signal perception and activation in the early signalling stage, the molecular mechanism underlying desensitization of ABA signalling remains largely unknown.
