[PMID: 36114867 DOI: 10.1007/s00403-022-02388-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2022] [Revised: 07/26/2022] [Accepted: 09/07/2022] [Indexed: 11/02/2022]
Abstract
Coffea canephora plant stem cells can have bioactive compounds with tissue repairing and anti-inflammatory action. This study aimed to develop a liposomal stem cell extract formulation obtained from the leaves of C. canephora (LSCECC) and to investigate its capacity to contribute to the dynamic mechanisms of tissue repair. The liposome cream was developed and characterized through the dynamic light scattering technique, atomic force microscopy, and transmission electron microscopy. The excisional full-thickness skin wound model was used and daily topically treated with the LSCECC formulation or vehicle control. On days 2, 7, 14, and 21 after wounding, five rats from each group were euthanized and the rates of wound closure and re-epithelialization were evaluated using biochemical and histological tests. LSCECC resulted in faster re-epithelialization exhibiting a significant reduction in wound area of 36.4, 42.4, and 87.5% after 7, 10, and 14 days, respectively, when compared to vehicle control. LSCECC treated wounds exhibited an increase in granular tissue and a proper inflammatory response mediated by the reduction of pro-inflammatory cytokines like TNF-α and IL-6 and an increase of IL-10. Furthermore, wounds treated with LSCECC showed an increase in the deposition and organization of collagen fibers at the wound site and improved scar tissue quality due to the increase in transforming growth factor-beta and vascular endothelial growth factor. Our data showed that LSCECC improves wound healing, the formation of extracellular matrix, modulates inflammatory response, and promotes neovascularization being consider a promising bioactive extract to promote and support healthy skin. The graphical presents the action of LSCECC in all four phases of wound healing and tissue repair. The LSCECC can reduce the inflammatory infiltrate in the inflammatory phase by decreasing the pro-inflammatory cytokines like IL-6 and TNF-α, in addition to maintaining this modulation through lesser activation and recruitment of macrophages. The LSCECC can also increase the release of IL-10, an anti-inflammatory cytokine, decreasing local edema. The increase in VEGF provides neovascularization and the supply of nutrients to newly repaired tissue. Finally, signaling via TGF-β increases the production and organization of collagen fibers in the remodeling phase.

Microbial community analyses provide a differential diagnosis for the antemortem and postmortem injury of decayed cadaver: An animal model. J Forensic Leg Med 2023; 93:102473.

Abstract
Differentiating antemortem injury from postmortem injury of decayed cadavers is one of the difficult issues in forensic science. Forensic pathologists identify antemortem injury according to the macroscopic and microscopic vital reactions taken place after being injured. However, the decomposition would render those vital reactions ineffective. Microbiomes have been widely used in forensic science due to their succession with time and sensitivity to vary of environment. In this study, microbiomes were introduced to determine whether the bacterial communities can be used to distinguish between the ante- and postmortem injuries through an animal experiment. Our findings showed that the differences of bacterial community were increasingly apparent from the 6th to 9th day after the wound created when the types of wounds were unidentified by morphological examination due to decomposition. The biomarkers at the genus level could effectively distinguish between injury types, Among them, Enterococcus and Enterobacter were only observed in the antemortem injured group, while Staphylococcus and Acinetobacter were only in the postmortem injured group. It is possible to tell whether cadaveric injuries developed before or after death by detecting differences in the bacterial communities of putrefying wounds. This study provides a new perspective for the differences between ante- and postmortem injuries and provides a promising method for us to identify the ante- and postmortem wounds, especially in decomposed cadavers.

Abstract
Periodontitis is a chronic infectious oral disease with a high prevalence rate in the world, and is a major cause of tooth loss. Nowadays, people have realized that the local microenvironment that includes proteins, cytokines, and extracellular matrix has a key influence on the functions of host immune cells and periodontal ligament stem cells during a chronic infectious disease such as periodontitis. The above pathological process of periodontitis will lead to a defect of periodontal tissues. Through the application of biomaterials, biological agents, and stem cells therapy, guided tissue regeneration (GTR) makes it possible to reconstruct healthy periodontal ligament tissue after local inflammation control. To date, substantial advances have been made in periodontal guided tissue regeneration. However, the process of periodontal remodeling experiences complex microenvironment changes, and currently periodontium regeneration still remains to be a challenging feat. In this review, we summarized the main challenges in each stage of periodontal regeneration, and try to put forward appropriate biomaterial treatment mechanisms or potential tissue engineering strategies that provide a theoretical basis for periodontal tissue engineering regeneration research.

Abstract
Understanding why some wounds are hard to heal is important for improving care and developing more effective treatments. The method of sample collection used is an integral step in the research process and thus may affect the results obtained. The primary objective of this study was to summarise and map the methods currently used to sample wound fluid for protein profiling and analysis. Eligible studies were those that used a sampling method to collect wound fluid from any human wound for analysis of proteins. A search for eligible studies was performed using MEDLINE, Embase and CINAHL Plus in May 2020. All references were screened for eligibility by one reviewer, followed by discussion and consensus with a second reviewer. Quantitative data were mapped and visualised using appropriate software and summarised via a narrative summary. After screening, 280 studies were included in this review. The most commonly used group of wound fluid collection methods were vacuum, drainage or use of other external devices, with surgical wounds being the most common sample source. Other frequently used collection methods were extraction from absorbent materials, collection beneath an occlusive dressing and direct collection of wound fluid. This scoping review highlights the variety of methods used for wound fluid collection. Many studies had small sample sizes and short sample collection periods; these weaknesses have hampered the discovery and validation of novel biomarkers. Future research should aim to assess the reproducibility and feasibility of sampling and analytical methods for use in larger longitudinal studies.

Abstract
C-reactive protein levels may have clinical value in monitoring different phases of healing and in identifying possible states of infection. As a critical step to further investigate this potential connection, we have demonstrated a lateral flow assay (LFA) for canine CRP level assessment in wound exudate that could be used as a tool in the veterinary clinic setting. In the rational design of our cCRP LFA, we have characterized LFA performance for sequential delivery mode vs. the more common premixed delivery mode using several metrics including dynamic range, sensitivity, limit of detection, and time to result. Although the sequential mode assay results indicated modestly improved signal (3-14%) and limit of detection (in the low ng/mL range for both) for this set of cCRP immunoassay reagents, the premixed mode assay's shorter run time with one less delivery step was chosen for use in this application in which analyte levels are substantially elevated. We have defined a straightforward wound exudate processing procedure that includes centrifugation to extract exudate from canine patient bandages, and subsequent sample dilution for cCRP quantification by our LFA. And, we have demonstrated that our cCRP LFA provides comparable cCRP concentrations to that of gold-standard ELISA performed on the same clinical wound exudate, and serum/plasma samples. Finally, we have highlighted some next steps in the assessment of cCRP as a biomarker for wound healing and infection.

Abstract
PURPOSE Effective management of wound pain is essential for optimal wound healing. Nevertheless, the outcomes of wound pain interventions are based on subjective measures, which can prove problematic in patients with cognitive impairment. Identification of biomarkers associated with wound pain and wound healing can be used to more objectively estimate wound pain and contribute to the development of precise management options to reduce wound pain and promote wound healing. This scoping review aimed to identify wound pain and wound healing biomarkers from wound exudates and to describe different wound collection methods to identify these biomarkers. METHODS We searched the literature (PROSPERO database registration number: CRD42018103843) via a scoping review. SEARCH STRATEGY The PubMed database was searched for articles that explored relationships between cutaneous wound pain, wound healing, and biomolecules. Inclusion criteria were articles that reported original data, used adult human samples, and were published in English. FINDINGS Twenty-one articles were retrieved: 17 investigated molecules from wound exudate associated with wound healing status, and 4 reported molecules associated with wound pain. The most frequently observed wound pain biomarkers were proinflammatory cytokines; the most frequently observed wound healing biomarkers were proteases including those in the matrix metalloproteinase family. Six wound exudate collection methods were identified to extract potential wound pain and wound healing biomarkers from wound exudate. IMPLICATIONS The results can guide future wound exudate research to validate these wound pain and wound healing biomarkers and to develop therapies targeting these biomarkers to reduce wound pain and promote wound healing.

Abstract
This work aimed to evaluate the in vivo capacity of a vegetable oil blend formulation (VOB) developed to accelerate cutaneous wound closure. Total thickness wounds were punctured on the skin on the back side of each animal and topically treated with the VOB formulation, Dersani® ointment or the vehicle control. After 2, 7, 14, 21 days post-wounding, five animals from each group were euthanized, and the rates of wound closure and re-epithelialization were evaluated. The wounds were harvested for histological and biochemical analysis. VOB resulted in faster and greater re-epithelialization in the in vivo excisional wounds, exhibiting significant wound area reduction of 8.9, 8.0, 35.1, 45.2 and 47.0% after 2, 5, 10, 14 and 21 days post-wounding, respectively, when compared with the vehicle control. Histological and biochemical analyses showed that the VOB-treated wounds exhibited a significant increase of granular tissue and controlled inflammatory response by modulation of the release of pro-inflammatory cytokines TNF-α, IL-6 and IL-1. Moreover, VOB-treated wounds showed a significant and concrete increase in the deposition and organisation of collagen fibres in the wound site and improved the quality of the scar tissue. Altogether, these data revealed that VOB accelerates wound healing processes and might be beneficial for treating wound disorders.

Abstract
Wound assessment is usually performed in hospitals or specialized labs. However, since patients spend most of their time at home, a remote real time wound monitoring would help providing a better care and improving the healing rate. This review describes the advances in sensors and biosensors for monitoring the concentration of C-reactive protein (CRP), temperature and pH in wounds. These three parameters can be used as qualitative biomarkers to assess the wound status and the effectiveness of therapy. CRP biosensors can be classified in: (a) field effect transistors, (b) optical immunosensors based on surface plasmon resonance, total internal reflection, fluorescence and chemiluminescence, (c) electrochemical sensors based on potentiometry, amperometry, and electrochemical impedance, and (d) piezoresistive sensors, such as quartz crystal microbalances and microcantilevers. The last section reports the most recent developments for wearable non-invasive temperature and pH sensors suitable for wound monitoring.
