Oral glucosamine sulfate (GS) and chondroitin sulfate (CS), while widely marketed as joint-protective supplements, have limited intestinal absorption and are predominantly utilized by gut microbiota. Hence the effects of these supplements on the gut microbiome are of great interest, and may clarify their mode of action, or explain heterogeneity in therapeutic responses. We conducted a systematic review of animal and human studies reporting the effects of GS or CS on gut microbial composition. We searched MEDLINE, EMBASE, and Scopus databases for journal articles in English from database inception until July 2018, using search terms microbiome, microflora, intestinal microbiota/flora, gut microbiota/flora and glucosamine or chondroitin. Eight original articles reported the effects of GS or CS on microbiome composition in adult humans (four articles) or animals (four articles). Studies varied significantly in design, supplementation protocols, and microbiome assessment methods. There was moderate-quality evidence for an association between CS exposure and increased abundance of genus Bacteroides in the murine and human gut, and low-quality evidence for an association between CS exposure and an increase in Desulfovibrio piger species, an increase in Bacteroidales S24-7 family, and a decrease in Lactobacillus. We discuss the possible metabolic implications of these changes for the host. For GS, evidence of effects on gut microbiome was limited to one low-quality study. This review highlights the importance of considering the potential influence of oral CS supplements on gut microbiota when evaluating their effects and safety for the host.

Background Laminaria japonica has frequently been used as a food supplement and drug in traditional oriental medicine. Among the major active constituents responsible for the bioactivities of L. japonica, fucoxanthin (FX) has been considered as a potential antioxidant. This study was conducted to examine the effects of L. japonica extract (LJE) or FX against oxidative stress on hepatocytes and to elucidate the overall their cellular mechanisms of the effects. Methods We constructed an in vitro model with the treatment of arachidonic acid (AA) + iron in HepG2 cells to stimulate the oxidative damage. The cells were pre-treated with LJE or FX for 1 h, and incubated with AA + iron. The effect on oxidative damage and cellular mechanisms of LJE or FX were assessed by cytological examination and several biochemical assays under conditions with or without kinase inhibitiors. Results LJE or FX pretreatment effectively blocked the pathological changes caused by AA + iron treatment, such as cell death, altered expression of apoptosis-related proteins such as procaspase-3 and poly (ADP-ribose) polymerase, and mitochondria dysfunction. Moreover, FX induced AMPK activation and AMPK inhibitor, compound C, partially reduced the protective effect of FX on mitochondria dysfunction. Consistent with AMPK activation, FX increased the protein levels of autophagic markers (LC3II and beclin-1) and the number of acridine orange stained cells, and decreased the phosphorylation of mTOR and simultaneously increased the phosphorylation of ULK1. And the inhibition of autophagy by 3-methylanine or bafilomycin A1 partially inhibited the protective effect of FX on mitochondria dysfunction. Conclusion These findings suggest that FX have the function of being a hepatic protectant against oxidative damages through the AMPK pathway for the control of autophagy.

Introduction and Objectives: Annually one million newborns die due to the umbilical cord infection. Thus, in this study, we aimed toevaluate the effect of topical aloe vera gel on umbilical cord complications. Methods: This randomized clinical trial was performed in maternity ward of Ghaem Hospital, Mashhad, Iran The samples were selected through convenience sampling and were randomly divided into three groups of aloe vera, control, and placebo. For data analysis, One-way ANOVA test was conducted. Results: Comparison of cord condition between the groups showed significant differences between the three groups. In the placebo group, the number of infants with redness around the cord was significantly higher compared to the control (P=0.002) and aloe vera (P=0.002) groups. In addition, cord swelling was significantly more frequent in the placebo group than the control (P=0.002) and aloe vera (P=0.002) groups. The incidence of cord infection was significantly higher in the placebo group than the control (P=0.000) and aloe vera (P=0.000) groups. The occurrence of infection in the umbilical cord of the newborns in the placebo group was significantly more compared to the control (P=0.000) and aloe vera (P=0.000) groups. Conclusion: Topical aloe vera gel accelerated cord separation and reduced the rates of complications and infections.

AbstractBackground: Inflammatory bowel disease (IBD) is associated with a widespread breakdown of glycosaminoglycans, which are normally attached to mucin and help to form a protective barrier separating bacteria from the intestinal epithelium. N-acetylglucosamine (NAG) is a naturally occurring amino sugar precursor for epithelial glycosaminoglycan synthesis. We hypothesize that NAG administration can alleviate IBD-related inflammation by increasing glycosaminoglycan synthesis, which would result in more glycosaminoglycan attachments to the protective mucin layer.

Beside biomaterials’ bulk properties, their surface properties are equally important to control interfacial biocompatibility. However, due to the inadequate interaction with tissue, they may cause foreign body reaction. Moreover, surface induced thrombosis can occur when biomaterials are used for blood containing applications. Surface modification of the biomaterials can bring enhanced surface properties in biomedical applications. Sulfated polysaccharide coatings can be used to avoid surface induced thrombosis which may cause vascular occlusion (blocking the blood flow by blood clot), which results in serious health problems. Naturally occurring heparin is one of the sulfated polysaccharides most commonly used as an anticoagulant, but its long term usage causes hemorrhage. Marine sourced sulfated polysaccharide fucoidan is an alternative anticoagulant without the hemorrhage drawback. Heparin and fucoidan immobilization onto a low density polyethylene surface after functionalization by plasma has been studied. Surface energy was demonstrated by water contact angle test and chemical characterizations were carried out by Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. Surface morphology was monitored by scanning electron microscope and atomic force microscope. Finally, their anticoagulation activity was examined for prothrombin time (PT), activated partial thromboplastin time (aPTT), and thrombin time (TT).

Aloe vera is a traditional wound‑healing medicine used for the treatment of skin disorders. Aloe polysaccharide (APS) is the main macromolecule of Aloe vera, which contributes to its function. Psoriasis is an immune‑mediated chronic inflammatory disease, which affects 2‑3% of the general population. The conventional remedies used to treat psoriasis demonstrate limited effects; therefore, natural products, including Aloe vera, are being taken into consideration. However, the effects of APS on the treatment of psoriasis and the underlying mechanisms remain to be elucidated. The human keratinocyte cell line HaCaT was used to determine the effects of APS on psoriasis. Cells were randomly divided into five groups: i) Negative control group; ii) tumor necrosis factor (TNF)‑α stimulated psoriasis model group; and iii) APS (20, 40 and 80 µg/ml) pretreated psoriasis groups. Cell viability and proliferation were investigated using the CCK‑8 assay. ELISA and western blotting were applied to study the abundance of interleukin (IL)‑8 and IL‑12 in TNF‑α‑incubated culture medium and APS‑treated HaCaT cells, respectively. In addition, the mRNA expression levels of p65, and the protein expression levels of nuclear factor (NF)‑κB inhibitor‑α (IκBα) and phosphorylated‑p65, were detected by reverse transcription‑quantitative polymerase chain reaction and western blotting, respectively. APS was revealed to significantly reduce TNF‑α‑stimulated elevation of HaCaT cell proliferation in a dose‑dependent manner. The expression levels of inflammatory factors, including IL‑8 and IL‑12, were increased in response to TNF‑α. In addition, the mRNA and protein expression levels of p65 were increased following treatment with TNF‑α. Notably, treatment with APS was demonstrated to significantly attenuate the aforementioned effects in a dose‑dependent manner. Furthermore, IκBα protein expression levels were significantly reduced following treatment with TNF‑α, which was significantly reversed following treatment with APS. In conclusion, these results suggested that APS inhibited TNF‑α‑induced proliferation of keratinocytes and overactivation of the NF‑κB signaling pathway.
