Fucoidan, a sulfated polysaccharide present in marine brown seaweed, has been demonstrated to inhibit in vivo and in vitro growth of cells. The present study was conducted in HT‑29 human colon cancer cells cultured at a high density, and examined the potential underlying mechanisms by which fucoidan exerts its anti‑proliferative effects, which remain poorly understood. Fucoidan treatment of high‑density HT‑29 cells resulted in the inhibition of cell growth and increased apoptotic cell death. Flow cytometric analysis revealed that fucoidan treatment led to sub‑G1 phase cell cycle arrest. This was associated with decreased protein expression levels of Retinoblastoma protein and E2 factor protein. In conclusion, the results of the present study demonstrated that fucoidan possesses anticancer activity against high density HT‑29 cells by inhibiting cell growth and cell cycle progression.
Gum acacia-PVA hydrogel blends for wound healing SpringerLink
Hydroactive wound dressings ensure a physiologically moist wound milieu which enhances healing and patient comfort. Polymers like polyurethane, salts of alginic acid, collagen, cellulose and other gelable polysaccharides are commonly used for preparation of hydrogels but have their own limitations. In the present study acacia gum, a natural polysaccharide having known antioxidant and wound healing properties has been blended with polyvinyl alcohol and prepared hydrogel matrix further explored for its wound healing potential. Structural characterization of blended films by FTIR and XRD method showed that polysaccharide gum associated with PVA molecules via acetal bridges and they were amorphous in nature. The gel exhibited free swell capacity of 64 g 0.100 cm−2, which is comparable to the commercially available films recommended for heavily exuding wounds. The GA/PVA blends showed 34% moisture retention (Rh) ability after 24 h and their fluid absorbing (26%) and fluid donation (16%) ability make them suitable for moist and fibrinous wounds. They also exhibited blood compatibility, oxygen permeability, bacterial impermeability, antioxidant activity, iron chelation ability and biodegradability. In vivo healing potential has been evaluated on Swiss albino mice where hydrogel coated wounds showed faster and scar-less wound regeneration. In vitro Povidone-Iodine loading and release studies showed that iodine release followed Fickian diffusion process. Prepared hydrogels are breathable and hydrophilic in nature and are able to maintain appropriate moisture level at wound surface, suitable for acceleration of wound healing process. Based upon the studied properties the designed hydrogels are recommended for dry, necrotic and low exuding wounds.
Antibacterial Properties of Aloe vera on Intracanal Medicaments against Enterococcus faecalis Biofilm at Different Stages of Development
Background. Use of herbal compounds as an intracanal medicament in the field of endodontics has become noteworthy, one of which is the Aloe vera compound whose antibacterial effect has already been proven in the planktonic form of Enterococcus faecalis. The purpose of this study is to evaluate the antibacterial effect of Aloe vera on E. faecalis biofilms at the 4th and 6th week of development. Materials and Methods. 130 single root canal teeth without anomalies and caries were used. They were divided into two groups of 65 teeth for four and six weeks of biofilm production. Five samples of each group were examined for confirmation of biofilm formation under an electron microscope. Study groups were investigated with an antimicrobial agent as an intracanal medicament including 20 samples treated with Aloe vera, calcium hydroxide, and phosphate-buffered saline, and biofilm and survival of pathogens were investigated. Dentin chip suspensions were used for colony-forming unit (CFU) counting to estimate remaining E. faecalis counts. Results. The CFU mean in the 4th week subgroup in Aloe vera, phosphate-buffered saline, and calcium hydroxide was 0, 69166.66 ± 31688.58, and 25000 ± 30822.07, and in the 6th week, it was 136.36 ± 323.33, 95000 ± 12247.44, and 27501.66 ± 36570.34, respectively, which showed a significant difference between the used materials (). Conclusion. Aloe vera, in contrast to calcium hydroxide, eliminated 4th and 6th week biofilms and showed remarkable antibacterial properties against E. faecalis biofilm. These results support potency of Aloe vera to use as a natural antimicrobial material in the intracanal medicament.

Effect of fucoidan on ethanol-induced liver injury and steatosis in mice and the underlying mechanism Food & Nutrition Research
Background: Alcoholic liver disease is caused as a result of chronic alcohol consumption. In this study, we used an alcoholic liver injury mouse model to investigate the effect of fucoidan on ethanol-induced liver injury and steatosis and the underlying mechanisms. Methods: All mice were randomly divided into four groups: 1) control group, 2) model group, 3) diammonium glycyrrhizinate treatment group (200 mg/kg body weight), and 4) fucoidan treatment group (300 mg/kg body weight). Administration of ethanol for 8 weeks induced liver injury and steatosis in mice. Results: Fucoidan treatment decreased serum alanine aminotransferase activity, serum total cholesterol levels, and hepatic triglyceride levels, and improved the morphology of hepatic cells. Fucoidan treatment upregulated the expression of AMPKα1, SIRT1, and PGC-1α and inhibited the expression of ChREBP and HNF-1α. The levels of hepatic IL-6 and IL-18 were significantly decreased in the fucoidan group. Further, the levels of cytochrome P450-2E1 (CYP2E1), glucose-regulated protein (GRP) 78, and 3-nitrotyrosine (3-NT) in hepatic tissues were reduced in the fucoidan group as compared to the model group. Fucoidan significantly reversed the reduction of ileac Farnesoid X receptor (FXR) and fibroblast growth factor 15 (FGF15) levels induced by alcohol- feeding and reduced CYP7A1 (cholesterol 7α-hydroxylase) expression and total bile acid levels in the liver tissue. In addition, fucoidan regulated the structure of gut flora, with increased abundance of Prevotella and decreased abundance of Paraprevotella and Romboutsia as detected by 16S rDNA high-throughput sequencing. Conclusion: Fucoidan inhibited alcohol-induced steatosis and disorders of bile acid metabolism in mice through the AMPKα1/SIRT1 pathway and the gut microbiota–bile acid–liver axis and protected against alcohol- induced liver injury in vivo.
