Biomedicines, Journal Year: 2021, Volume and Issue: 9(9), P. 1235 - 1235

Published: Sept. 16, 2021

Chronic wounds do not progress through the wound healing process in a timely manner and are considered burden for healthcare system; they also most common reason decrease patient quality of life. Traditional dressings e.g., bandages gauzes, although highly absorbent effective dry to mild, exudating wounds, require regular application, which therefore can cause pain upon dressing change. In addition, have poor adhesional properties cannot provide enough drainage wound. this regard, normalization chronic is an extremely urgent task public health requires creation implementation affordable patients with wounds. Modern (WDs) aimed solve these issues. At same time, hydrogels, unlike other types modern WDs (foam, films, hydrocolloids), positive degradation that makes them perfect choice applications where targeted delivery bioactive substances required. This mini review focused on different traditional emphasis hydrogels. Advantages disadvantages as well their applicability elucidated. Furthermore, effectiveness comparison between hydrogel some frequently used biotechnologies field regenerative medicine (adipose-derived mesenchymal stem cells (ADMSCs), cells, conditioned media, platelet-rich plasma (PRP)) provided.

Chronic wounds are defined as that fail to proceed through the normal phases of wound healing in an orderly and timely manner. The most common inevitable impairment is installation infection, usually case chronic wounds. Therefore, objective present review was identify importance copper nanoparticles dressings for healing. Nanoparticles such silver, gold combat infectious processes inhibition protein synthesis, peroxidation cell membrane destroying nucleic acids bacteria viruses. Among bioactive nanoparticles, plays a complex role various cells, it modulates several cytokines growth factor mechanisms action essentially involved all stages process. More importantly, key skin regeneration angiogenesis accelerates process induction vascular endothelial (VEGF) by hypoxia-induced factor-1-alpha (HIF-1α) where enhances HIF-1α expression binding critical motifs promoter putative enhancer regions HIF-1-regulated genes.

Multifunctional Hydrogels for the Healing of Diabetic Wounds

Advanced Healthcare Materials, Journal Year: 2023, Volume and Issue: 13(1)

Published: Sept. 13, 2023

Abstract The healing of diabetic wounds is hindered by various factors, including bacterial infection, macrophage dysfunction, excess proinflammatory cytokines, high levels reactive oxygen species, and sustained hypoxia. These factors collectively impede cellular behaviors the process. Consequently, this review presents intelligent hydrogels equipped with multifunctional capacities, which enable them to dynamically respond microenvironment accelerate wound in ways, stimuli ‐responsiveness, injectable self‐healing, shape ‐memory, conductive real‐time monitoring properties. relationship between multiple functions also discussed. Based on wounds, antibacterial, anti‐inflammatory, immunomodulatory, antioxidant, pro‐angiogenic strategies are combined hydrogels. application repair systematically discussed, aiming provide guidelines for fabricating exploring role therapeutic processes.
