[PMID: 38202459 PMCID: PMC10780749 DOI: 10.3390/nano14010004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/11/2023] [Revised: 12/09/2023] [Accepted: 12/11/2023] [Indexed: 01/12/2024]
Abstract
To reduce and prevent postsurgical adhesions, a variety of scientific approaches have been suggested and applied. This includes the use of advanced therapies like tissue-engineered (TE) biomaterials and scaffolds. Currently, biocompatible antiadhesive constructs play a pivotal role in managing postoperative adhesions and several biopolymer-based products, namely hyaluronic acid (HA) and polyethylene glycol (PEG), are available on the market in different forms (e.g., sprays, hydrogels). TE polymeric constructs are usually associated with critical limitations like poor biocompatibility and mechanical properties. Hence, biocompatible nanocomposites have emerged as an advanced therapy for postoperative adhesion treatment, with hydrogels and electrospun nanofibers among the most utilized antiadhesive nanocomposites for in vitro and in vivo experiments. Recent studies have revealed that nanocomposites can be engineered to generate smart three-dimensional (3D) scaffolds that can respond to different stimuli, such as pH changes. Additionally, nanocomposites can act as multifunctional materials for the prevention of adhesions and bacterial infections, as well as tissue healing acceleration. Still, more research is needed to reveal the clinical potential of nanocomposite constructs and the possible success of nanocomposite-based products in the biomedical market.

Atorvastatin Inhibits Ferroptosis of H9C2 Cells by regulatingSMAD7/Hepcidin Expression to Improve Ischemia-Reperfusion Injury. Cardiol Res Pract 2022; 2022:3972829. [PMID: 36398315 PMCID: PMC9666047 DOI: 10.1155/2022/3972829] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/14/2022] [Accepted: 10/27/2022] [Indexed: 11/09/2022] Open
Abstract
Background Ferroptosis plays a key role in cardiomyopathy. Atorvastatin (ATV) has a protective effect on ischemia-reperfusion (I/R) cardiomyopathy. The purpose of this study is to elucidate the mechanism of ATV in I/R injury. Methods H9C2 cells and cardiomyopathy rats were induced by hypoxia/reoxygenation (H/R) and I/R to construct in vitro and in vivo models. Cell viability was determined by CCK8. Cardiac histopathology was observed by HE staining. Transmission electron microscope (TEM) was used to observe the mitochondrial morphology. The reactive oxygen species (ROS) content in cells was analyzed by the biochemical method. ELISA was conducted to calculate the concentrations of total iron/Fe2+ and hepcidin. The expression of ferroptosis and SMAD pathway-related genes were detected by qPCR. Western blot was performed to detect the expression levels of ferroptosis and SMAD pathway-related proteins. Results In H9C2 cells, ATV reversed the decline in cell viability, mitochondrial shrinkage, and ROS elevation induced by erastin or H/R. The concentration of total iron and Fe2+ in H/R-induced H9C2 cells increased, and the protein expression of FPN1 decreased. After ATV treatment, the concentration of total iron and Fe2+ decreased, and the protein expression of FPN1 increased. The expression of the SMAD7 gene in H/R-induced H9C2 cells decreased, and the expression of the hepcidin gene increased, which were reversed by ATV. When SMAD7 was knocked down, ATV treatment failed to produce the above effect. ATV also improved ferroptosis in I/R rat myocardium through the SMAD7/hepcidin pathway. Conclusions ATV reversed the decline in H9C2 cell viability, mitochondrial shrinkage, and ROS elevation, and improved the myocardium ferroptosis through the SMAD7/hepcidin pathway in I/R rat.

Abstract
Peritoneal adhesion represents a severe complication following surgery. Punica granatum (pomegranate) possesses several anti-oxidative and anti-inflammatory properties. Pomegranate peel extract (PPEx) can alleviate the production of various inflammatory factors and cytokines. Thus, we sought to evaluate the anti-adhesion effects of pomegranate in rats. Thirty male Wistar rats (6-week-old, 220 ± 20 g) were divided into five groups (n = 6): normal group without any surgical procedures, control group, and experimental groups receiving 2 ml of 1%, 2%, and 4% w/v PPEx, respectively. Peritoneal adhesions were examined macroscopically. Furthermore, we evaluated inflammatory cytokines levels [interleukin 6 (IL-6), and tumour necrosis factor-α (TNF-α)], growth factors [transforming growth factor- β1 (TGF-β1), and vascular endothelial growth factor (VEGF)], and oxidative stress parameters [nitric oxide metabolites (NO), and malondialdehyde (MDA), and glutathione (GSH)] using biochemical methods. Our results showed that the adhesion score and IL-6, TNF-α, TGF-β1, VEGF, NO, and MDA levels were increased in the control group. In contrast, the GSH level was diminished in the control group compared with the normal group (P < 0.001). PPEx (1 and 2% w/v) markedly reduced all measured parameters compared with the control group (P < 0.001-0.05). PPEx may reduce peritoneal adhesion by alleviating adhesion formation, IL-6, TNF-α, TGF-β1, VEGF, NO, and MDA, and stimulating anti-oxidative factors. Therefore, PPEx may be considered an appropriate candidate for the treatment of postoperative peritoneal adhesion.

Abstract
Peritoneal adhesion occurs in a majority of patients following abdominal surgery and can result in significant side effects and complications. Current strategies to minimize adhesions involve the use of nontargeted anatomical barriers that are either inefficient in protecting injured areas or lacking the adequate residence time to prevent adhesions. Herein, the development of a biologically targeted photo-crosslinkable nanopatch (pCNP) is reported that can prevent postsurgical adhesion. It is demonstrated that pCNP can form a compact protective barrier over surfaces with exposed collagen IV. Using a rat parietal peritoneal excision adhesion model, it is showed that pCNP is highly effective and safe in preventing postsurgical adhesions. This work presents a novel approach to preventing peritoneal adhesion with nanomaterials.

Abstract
Advanced wound dressings capable of interacting with lesions and changing the wound microenvironment to improve healing are promising to increase the therapeutic efficacy of this class of biomaterials. Aiming at the production of bioactive wound dressings with the ability to control the wound microenvironment, biomaterials of three different chemical compositions, but with the same architecture, were produced and compared. Electrospinning was employed to build up a biomimetic extracellular matrix (ECM) layer consisting of poly(caprolactone) (PCL), 50/50 dl-lactide/glycolide copolymer (PDLG) and poly(l-lactide) (PLLA). As a post-treatment to broaden the bioactivity of the dressings, an alginate coating was applied to sheathe and functionalize the surface of the hydrophobic electrospun wound dressings, in combination with the extract of the plant Arrabidaea chica Verlot, known for its anti-inflammatory and healing promotion properties. Wettable bioactive structures capable to interact with media simulating lesion microenvironments, with tensile strength and elongation at break ranging respectively from 155 to 273 MPa and from 0.94 to 1.39% were obtained. In simulated exudative microenvironment, water vapor transmission rate (WVTR) values around 700 g/m2/day were observed, while water vapor permeability rates (WVPR) reached about 300 g/m2/day. In simulated dehydrated microenvironment, values of WVTR around 200 g/m2/day and WVPR around 175 g/m2/day were attained.

Abstract
Lack of potential regenerative medicine to reconstruct damaged cartilage tissue has accelerated investigation and development of potential biomaterial for cartilage tissue engineering. In this study, we fabricated micron-sized non-mulberry silk fibroin fiber (SFF) using N,N-Dimethylacetamide (DMAC)/10% LiBr solution and further used to develop SFF reinforced chitosan(CH) based porous scaffold with desired pore size, porosity, swelling and structural stability. The developed scaffold was characterized for its various physico-chemical, mechanical and biological properties. The developed CH/SFF composite scaffold facilitates human mesenchymal stem cell (hMSCs) attachment, colonization and extracellular matrix deposition. Furthermore, hMSCs shows significantly higher sulfated glycosaminoglycan deposition over CH/SFF in comparison to pure chitosan scaffold (control). Immunocytochemistry studies have shown enhanced expression of collagen type II and aggrecan by hMSCs over composite scaffold than chitosan scaffold. Thus, non-mulberry silk fibroin fiber reinforced chitosan based scaffold might be suitable scaffold that can act as a potential artificial matrix for cartilage tissue engineering.
