Abstract Diabetes significantly impairs the body's wound‐healing capabilities, leading to chronic, infection‐prone wounds. These wounds are characterized by hyperglycemia, inflammation, hypoxia, variable pH levels, increased matrix metalloproteinase activity, oxidative stress, and bacterial colonization. complex conditions complicate effective wound management, prompting development of advanced diabetic care strategies that exploit specific characteristics such as acidic pH, high glucose stress trigger controlled drug release, thereby enhancing therapeutic effects dressings. Among solutions, hydrogels emerge promising due their stimuli‐responsive nature, making them highly for managing these The latest advancements in mono/multi‐stimuli‐responsive smart showcase superiority potential healthcare materials, highlighted relevant case studies. However, traditional dressings fall short meeting nuanced needs wounds, adjustable adhesion, easy removal, real‐time status monitoring, dynamic release adjustment according wound's conditions. Responsive represent a significant leap forward proficient sensing responding environment, offering more targeted approach treatment. This review highlights recent dressing, delivery, emphasizing role improving healing. It addresses ongoing challenges future directions, aiming guide clinical adoption.

Every cell in the body is exposed to a certain level of CO2 and O2. Hypercapnia hypoxia elicit stress signals influence cellular metabolism function. Both conditions exert profound yet distinct effects on metabolic pathways mitochondrial dynamics, highlighting need for cells adapt changes gaseous microenvironment. The interplay between hypercapnia signalling key dictating homeostasis as microenvironmental O2 levels are inextricably linked. Hypercapnia, characterized by elevated pCO₂, introduces adaptations within aerobic pathways, affecting TCA cycle flux, lipid, amino acid metabolism, OXPHOS ETC. Hypoxia, defined reduced oxygen availability, necessitates shift from anaerobic glycolysis sustain ATP production, process orchestrated stabilisation HIF-1α. Given that present both physiological cancerous microenvironments, how might coexistence function niches tumor microenvironment?

Redox homeostasis, the delicate balance between oxidative and reductive processes, is crucial for cellular function overall organismal health. At molecular level, cells need to maintain a fine levels of reactive oxygen species (ROS) reducing equivalents such as glutathione nicotinamide adenine dinucleotide phosphate. The perturbation redox homeostasis due excessive ROS production leads stress that can damage lipids, proteins, nucleic acids. Conversely, an overly reduced environment overabundant results in stress, which also interferes with important signaling physiological processes. Disrupted linked various pathological conditions, including neurodegenerative diseases, inflammatory cancer, cardiovascular diseases. Cells employ diverse mechanisms manage imbalance. hypoxia response pathway, mediated by hypoxia‐inducible factors responsible sensing defending against low levels, plays vital role maintaining homeostasis. In this review, we highlight complex multifaceted crosstalk discuss avenues future research. Understanding link stresses essential comprehending several conditions associated
