Poor wound healing affects millions of people globally, resulting in increased mortality rates and associated expenses. The three major complications associated with wounds are: (i) the lack of an appropriate environment to enable the cell migration, proliferation, and angiogenesis; (ii) the microbial infection; (iii) unstable and protracted inflammation. Unfortunately, existing therapeutic methods have not solved these primary problems completely, and, thus, they have an inadequate medical accomplishment. Over the years, the integration of the remarkable properties of nanomaterials into wound healing has produced significant results. Nanomaterials can stimulate numerous cellular and molecular processes that aid in the wound microenvironment via antimicrobial, anti-inflammatory, and angiogenic effects, possibly changing the milieu from nonhealing to healing. The present article highlights the mechanism and pathophysiology of wound healing. Further, it discusses the current findings concerning the prospects and challenges of nanomaterial usage in the management of chronic wounds.

Monitoring deep wounds is challenging but necessary for high-quality medical treatment. Current methodologies for deep wound monitoring are typically limited to indirect clinical symptoms or costly non-real-time imaging diagnosis. Herein, a smart system is proposed that enables in situ monitoring of deep wounds' status through a semi-implantable device composed of 2 seamlessly connected functional components: 1) the well-designed, microchannel-structured sampling needles that efficiently and conveniently collect samples from deep wound anatomical locations, and 2) the multiplex biochemical testing compartment that facilitates the immediate and persistent detection of multiple biochemical indicators based on a color image processing software accessible to a conventional smartphone.

In this study, we characterized a variant hESC (vhESC) line and investigated the molecular mechanisms leading to the drift towards a transformed state. Our findings revealed that vhESCs up-regulate EMT-specific markers, accelerate wound healing, exhibit compromised lineage differentiation, and retain pluripotency gene expression in teratomas.

Background/aim: Hydrogen therapy has demonstrated potential as an antioxidant and anti-inflammatory intervention, particularly in the management of chronic diseases such as chronic kidney disease (CKD) and autoimmune conditions. This case report presents the possible therapeutic benefits of molecular hydrogen capsule treatment in enhancing renal function and alleviating chronic fatigue in an elderly female with coronary artery disease (CAD), type 2 diabetes mellitus (DM) complicated by nephropathy, and systemic lupus erythematosus (SLE). The aim of this study was to investigate the efficacy of adjunctive hydrogen therapy in an elderly patient with multiple chronic comorbidities.

Background/aim: Organometallic complexes can decrease adhesion, migration, invasion of cancer cells, mainly through regulation of the extracellular matrix and therefore act against metastases. The aim was to investigate the anti-invasive properties of a rhenium-based metal compound, rhenium(I)-diselenoether (Re-diSe) and its effects on matrix metalloproteinase MMP-2, a key player in metastatic processes, in cultured MDA-MB231 triple-negative breast cancer cells.
Materials And Methods: Matrigel was utilized to assess cancer cell adhesion to the extracellular matrix.

The self-assembled peptide RADA16-I (RADARADARADARADA) has been widely used in biomaterials. However, studies on the practical application of self-assembled peptide hydrogels loaded with bioactive peptides are still insufficient. In this study, we successfully prepared the peptide nanofiber gel RGJ by incorporating the bioactive peptides A8SGLP-1 (G) and Jagged-1 (J) into RADA16-I (R) in specific ratios.
