Skeletal organoids.

The skeletal system, composed of bones, muscles, joints, ligaments, and tendons, serves as the foundation for maintaining human posture, mobility, and overall biomechanical functionality. However, with ageing, chronic overuse, and acute injuries, conditions such as osteoarthritis, intervertebral disc degeneration, muscle atrophy, and ligament or tendon tears have become increasingly prevalent and pose serious clinical challenges. These disorders not only result in pain, functional loss, and a marked reduction in patients' quality of life but also impose substantial social and economic burdens.

Metabolomics reveals the effect of vacuum packaging combined with moderate-temperature preservation on quality changes of tender ginger.

Tender ginger is often used a fresh vegetable but hard to storage due to the delicate skin, high moisture content and prone to spoilage. In order to develop suitable preservation technology for tender ginger, the effects of vacuum packaging combined with different preservation temperatures (20-25 °C room temperature, 4 °C and 10 °C) on tender ginger shelf life were investigated. The results indicated that vacuum packaging combined with 4 °C (VP4) preservation could easily cause cold damage and postharvest physiological fluctuations.

RL-QPSO net: deep reinforcement learning-enhanced QPSO for efficient mobile robot path planning.

Introduction: Path planning in complex and dynamic environments poses a significant challenge in the field of mobile robotics. Traditional path planning methods such as genetic algorithms, Dijkstra's algorithm, and Floyd's algorithm typically rely on deterministic search strategies, which can lead to local optima and lack global search capabilities in dynamic settings. These methods have high computational costs and are not efficient for real-time applications.

Effect of in vivo reprogramming of astrocytes combined with exercise training on neurorepair in rats with spinal cord injury.

Background: The inability of damaged neurons to regenerate and of axons to establish new functional connections leads to permanent functional deficits after spinal cord injury (SCI). Although astrocyte reprogramming holds promise for neurorepair in various disease models, it is not sufficient on its own to achieve significant functional recovery.

Methods: A rat SCI model was established using a spinal cord impactor.

Recyclable and air-stable colloidal manganese nanoparticles catalyzed hydrosilylation of alkenes with tertiary silane.

We synthesized ,-dimethylformamide (DMF)-stabilized manganese nanoparticles (Mn NPs) in a one-step process under air using manganese(ii) chloride as the precursor. The Mn NPs were characterized in terms of particle size, oxidation state, and local structure using annular dark-field scanning transmission electron microscopy (ADF-STEM), X-ray photoelectron spectroscopy (XPS), and X-ray absorption spectroscopy (XAS). The results indicate that Mn NPs are divalent nanosized particles with Mn-O bonds.
