Human amniotic membrane (HAM) was a biocompatible scaffold with advantages of anti-inflammatory, low antigen, feasibility, tolerance and low cost. In our previous work, HAM was treated to be decellularized using surfactant, lipase and DNAase methods and the efficacy as an implantable biological mesh was verified after decellularization treatment. In this work, we used the previous protocol to decellularize the fresh HAM, and applied it to repair full-thickness skin defects with Sprague-Dawley rats as the test animals...

In this work, hybrid melanin-coated bioactive glass-ceramic multifunctional scaffolds were developed and characterized in terms of mechanical strength, in vitro bioactivity in simulated body fluid (SBF) and ability to load ibuprofen. The coated scaffolds exhibited an accelerated bioactivity in comparison with the uncoated ones, being able of developing hydroxyapatite-like crystals after 7days soaking in simulated body fluid (SBF). Besides its positive influence on the scaffolds bioactivity, the melanin coating was able to enhance their mechanical properties, increasing the initial compressive strength by a factor of >2...

Curcumin derivatives have been well-documented due to their natural antioxidant, antimicrobial and anti-inflammatory activities. Curcuminoids have also gained widespread recognition due to their wide range of other activities which include anti-infective, anti-mutagenic, anticancer, anti-coagulant, antiarthrititc, and wound healing potential. Despite of having a wide range of activities, the inherent physicochemical characteristics (poor water solubility, low bioavailability, chemical instability, photodegradation, rapid metabolism and short half-life) of curcumin derivatives limit their pharmaceutical significance...

Gold nanoparticles (GNPs) have antioxidant and anti-inflammatory effects. However, toxicity is still a concern; therefore, it is critical to study both the therapeutic and toxic properties of GNPs. In this study, we evaluated the effects of the intraperitoneal administration of GNPs (20nm, at a concentration of 2.5mg/L for 21days) every 24 or 48h on oxidative stress, antioxidant status, and electron chain transport (ETC) in the brain. Liver histology and blood marker analyses were conducted to establish a time routine of GNP administration...

A massage with the potent counter-inflammatory material, cerium dioxide nanoparticles, is promising and the antioxidant properties of CeO2 are considered the main, if not the only, mechanism of this action. Nevertheless, the elimination of ceria nano-particles from the organism is very slow and there is a strong concern for toxic effect of ceria due to its accumulation. To overcome this problem, we engineered a combined material in which cerium nanoparticles were immobilized on the surface of silica nanoparticles (CeO2 NP), which is shown to be easily removed from an organism and could be used as carriers for nano-ceria...

Yasuhiro Watanabe, Ichiro Tatsuno
Large-scale epidemiological studies on Greenlandic, Canadian and Alaskan Eskimos have examined the health benefits of omega-3 fatty acids consumed as part of the diet, and found statistically significant relative reduction in cardiovascular risk in people consuming omega-3 fatty acids. Areas covered: This article reviews studies on omega-3 fatty acids during the last 50 years, and identifies issues relevant to future studies on cardiovascular (CV) risk. Expert Commentary: Although a meta-analysis of large-scale prospective cohort studies and randomized studies reported that fish and fish oil consumption reduced coronary heart disease-related mortality and sudden cardiac death, omega-3 fatty acids have not yet been shown to be effective in secondary prevention trials on patients with multiple cardiovascular disease (CVD) risk factors...

Historically, Mangifera indica L. cultivations have been widely planted in tropical areas of India, Africa, Asia, and Central America. However, at least 20 years ago its spreading allowed the development of some cultivars in Sicily, an island to the south of Italy, where the favourable subtropical climate and adapted soils represent the perfect field to create new sources of production for the Sicilian agricultural supply chain. Currently, cultivations of Kensington Pride, Keitt, Glenn, Maya, and Tommy Atkins varieties are active in Sicily and their products meet the requirements of local and European markets...

BACKGROUND: Corrosive esophageal burns, particularly common in developing countries, lead to different problems in different age groups. The ingestion of corrosive substances can cause such problems as stricture of the esophagus, to acute perforation, and even death. Because stricture formation is related to the severity of the initial injury, the prevention of stricture constitutes a main goal of treatment. The aim of this study was to investigate the protective and anti-inflammatory effects of garlic (Allium sativum) oil in corrosive esophageal burn...

Limited biocompatibility of decellularized scaffolds is an ongoing challenge in tissue engineering. We recently demonstrated that intensified detergent-based decellularization of equine carotid artery (dEACintens) removed residual cellular molecules from the scaffold more efficiently than a conventional decellularization (dEACcon) though this approach did not eliminate its immunogenicity entirely. CCN1 has been shown to improve biocompatibility of dEACcon in a sheep model. Here, we tested the biocompatibility of dEACintens and dEACcon with or without CCN1-coating after subcutaneous implantation in rats for up to 12 weeks...

Alopecia areata (AA) is an organ specific autoimmune disease. Similar to other autoimmune diseases, its pathogenesis is believed to be an interaction of genetic, environmental and immune factors. Studies have shown that autoreactive lymphocytes affect anagen hair follicles leading to subsequent shedding of hairs and alopecia. Clinically, the disease is characterized by sudden nonscarring hair loss that usually involves the scalp, but may also affect the face and other body areas, and indeed the entire body hair...
