The management of acute and chronic wounds resulting from diverse injuries poses a significant challenge to clinical practices and healthcare providers. Wound healing is a complex biological process driven by a natural physiological response. This process involves four distinct phases, namely hemostasis, inflammation, proliferation, and remodeling. Despite numerous investigations on wound healing and wound dressing materials, complications still persist, necessitating more efficacious therapies. Wound-healing materials can be categorized into natural and synthetic groups. The current study aims to provide a comprehensive review of highly active natural animal and herbal agents as wound-healing promoters. To this end, we present an overview of in vitro, in vivo, and clinical studies that led to the discovery of potential therapeutic agents for wound healing. We further elucidated the effects of natural materials on various pharmacological pathways of wound healing. The results of previous investigations suggest that natural agents hold great promise as viable and accessible products for the treatment of diverse wound types.

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.
