Multifunctional hydrogel loaded with 4-octyl itaconate and exosomes to induce bone regeneration for diabetic infected bone defect via Keap1-Nrf2 pathway.

Diabetic infected bone defect remains a great challenge in clinical practice, with delayed healing characterized by bacterial infection and cellular disfunction caused by oxidative stress. Hence, a novel self-healing multifunctional Ag@PEG-4OI/EXO hydrogel is introduced for improving healing of diabetic infected bone defect. 4-octyl itaconate, a derivative of the metabolite itaconate, has been proved that which performs antioxidant and mitochondria-protected properties.

Localized propranolol delivery from a copper-loaded hydrogel for enhancing infected burn wound healing via adrenergic β-receptor blockade.

Severe burn injuries immediately trigger a sustained systemic and local stress response. During this process, the sympathetic nervous system releases large amounts of catecholamines, which bind to β-adrenergic receptors (β-AR) on cell membranes, negatively affecting skin regeneration. Additionally, recurrent bacterial infections make burn wounds difficult to treat, posing significant and ongoing challenges to burn care.

Upregulation of C1QC as a Mediator of Blood-Brain Barrier Damage in Type 2 Diabetes Mellitus.

The blood-brain barrier (BBB) is a neurovascular structure that safeguards the brain by inhibiting the passage of harmful substances. In individuals with type 2 diabetes mellitus (T2DM), the heightened blood glucose may cause damage to endothelial cells and neurons, increase collagen protein content, and elevate BBB permeability. Although the impact of blood glucose regulation on the structure and function of BBB has been documented, the exact mechanism remains incompletely elucidated.

A fault isolation strategy for industrial processes using outlier-degree-based variable contributions.

In industrial process monitoring, it is always a challenging and practical problem to analyze the causes of the system fault by isolating true fault variables from vast amounts of process data. However, the phenomenon of smearing effect occurs by using the traditional contribution analysis-based isolation methods since the defined isolation indices of different variables affect each other. In this paper, a new fault isolation method is proposed based on local outlier factor and improved k-nearest neighbor rule aiming to improve the isolation accuracy.
