One of the greatest challenges faced during surgical procedures is closing and healing of wounds, which are essential in the field of orthopaedics, trauma, intensive care and general surgery. One of the main causes of death has been linked to chronic wounds, especially in immunosuppressant or diabetic patients. Due to increasing chronic wound fatality along with different pathologies associated with them, the current therapeutic methods are insufficient which has established an eminent need for innovative techniques. Traditionally, wound healing was carried out using formulations and ointments containing silver combined with different biomaterial, but was found to be toxic. Hence, the advent of alternative nanomaterial-based therapeutics for effective wound healing have come into existence. In this review, we have discussed an overview of wound infections such as different wound types, the wound healing process, dressing of wounds and conventional therapies. Furthermore, we have explored various nanotechnological advances made in wound healing therapy which include the use of promising candidates such as organic, inorganic, hybrid nanoparticles/nanocomposites and synthetic/natural polymer-based nanofibers. This review further highlights nanomaterial-based applications for regeneration of tissue in wound healing and can provide a base for researchers worldwide to contribute to this advancing medical area of wound therapy.

Background: Intestinal cells receive incoming signals from neighboring cells and microbial communities. Upstream signaling pathways transduce these signals to reach transcription factors (TFs) that regulate gene expression. In inflammatory bowel disease (IBD), most single nucleotide polymorphisms (SNPs) are in non-coding genomic regions containing TF binding sites.

Normal cutaneous wound healing is a multicellular process that involves the release of small extracellular vesicles (sEVs) that coordinate intercellular communication by delivery of sEV payloads to recipient cells. We have recently shown how the pro-reparative activity of inflammatory cell sEVs, especially macrophage and neutrophil-derived sEVs, in the wound bed is dysregulated in impaired wound healing. Here we show that loss of Rab27A, a small GTPase that has a regulatory function in sEV secretion, reduces the release of neutrophil and macrophage-derived sEVs.

Wound healing is often hindered by bacterial infection, oxidative stress, and bleeding. Traditional dressings cannot simultaneously regulate multiple microenvironments. To address the shortcomings of traditional dressings, this study constructed a dual-network photothermal responsive multifunctional hydrogel OBCTCu based on four natural ingredients, including Bletilla striata polysaccharide (BSP), chitosan (CS), tannic acid (TA), and Cu.

Conventional wound dressings primarily focus on biochemical regulation, often neglecting the potential benefits of mechanical cues in tissue regeneration. We report a Janus hydrogel (QPJ hydrogel) that synergistically integrates biochemical modulation with temperature-responsive mechanical contraction for advanced chronic wound management. The hydrogel is constructed from quaternary ammonium chitosan (QCS) and N-isopropylacrylamide (NIPAM), with an outer PNIPAM layer that generates a directional contractile stress >25 kPa at physiological temperature.

Objective: Polychlorinated dibenzo-p-dioxins (PCDDs) present a significant long-term threat to human health attributable to their toxicological properties, chemical stability and propensity for bioaccumulation. This study seeks to explore the correlation between PCDDs exposure and prostate cancer (PCa) through comprehensive analysis.
Methods: The multi-dimensional analysis was conducted based on various online databases.
