In the open metabolic system, redox-related signaling requires continuous monitoring and fine-tuning of steady-state redox set point. The ongoing oxidative metabolism is a persistent challenge, denoted as eustress, which operates within physiological range that has been called 'Homeodynamic Space', 'Goldilocks Zone' or 'Golden Mean'. Spatiotemporal control achieved by compartmentalized generation removal oxidants. cellular landscape H2O2, major molecule, characterized orders-of-magnitude concentration differences between organelles. This pattern mirrored oxidatively modified proteins, exemplified S-glutathionylated proteins. review presents conceptual background for short-term (non-transcriptional) longer-term (transcriptional/translational) homeostatic mechanisms stress responses. point variable moving target value, modulated circadian rhythm external influence, summarily exposome, includes nutrition lifestyle factors.

Interventional coronary reperfusion strategies are widely adopted to treat acute myocardial infarction, but morbidity and mortality of infarction still high. Reperfusion injuries inevitable due the generation reactive oxygen species (ROS) apoptosis cardiac muscle cells. However, many antioxidant anti-inflammatory drugs largely limited by pharmacokinetics route administration, such as short half-life, low stability, bioavailability, side effects for treatment ischemia injury. Therefore, it is necessary develop effective technologies address this issue.

Abstract Alzheimer’s disease (AD) stands as the predominant form of dementia, presenting significant and escalating global challenges. Its etiology is intricate diverse, stemming from a combination factors such aging, genetics, environment. Our current understanding AD pathologies involves various hypotheses, cholinergic, amyloid, tau protein, inflammatory, oxidative stress, metal ion, glutamate excitotoxicity, microbiota-gut-brain axis, abnormal autophagy. Nonetheless, unraveling interplay among these pathological aspects pinpointing primary initiators require further elucidation validation. In past decades, most clinical drugs have been discontinued due to limited effectiveness or adverse effects. Presently, available primarily offer symptomatic relief often accompanied by undesirable side However, recent approvals aducanumab ( 1 ) lecanemab 2 Food Drug Administration (FDA) present potential in disrease-modifying Nevertheless, long-term efficacy safety need Consequently, quest for safer more effective persists formidable pressing task. This review discusses pathogenesis, advances diagnostic biomarkers, latest updates trials, emerging technologies drug development.

An essential challenge in diabetic periodontal regeneration is achieving the transition from a hyperglycemic inflammatory microenvironment to regenerative one. Here, we describe polydopamine (PDA)-mediated ultralong silk microfiber (PDA-mSF) and metformin (Met)-loaded zeolitic imidazolate framework (ZIF) incorporated into fibroin/gelatin (SG) patch promote soft hard tissue by regulating immunomodulatory microenvironment. The PDA-mSF endows with reactive oxygen species (ROS)-scavenging ability anti-inflammatory activity, reducing response suppressing M1 macrophage polarization. Moreover, PDA improves ligament reconstruction via its cell affinity. Sustained release of Met Met-ZIF system confers antiaging abilities activating M2 polarization secrete osteogenesis-related cytokines, while Zn2+ also promotes bone regeneration. Consequently, creates favorable for These features synergistically accelerate Thus, our findings offer potential therapeutic strategy periodontitis.
