3%, respectively). Also, the central MS XOS, exerted the highest cholesterol reduction and antioxidant activities 74.7 and 92%, respectively, showed remarkable in vivo protective role against the hepatic toxicity of lithium carbonate evaluated by changes in body weight, liver function markers (AST, ALT, Alb, total bilirubin) and tissue makers (MDA and GSH).An enzyme hyaluronidase (hyase) producing halotolerant bacterium was isolated from dental caries and identified as Brevibacterium halotolerans DC1. Higher growth and hyase production were observed in nutrient broth fortified with hyaluronic acid at pH 7.0, temperature 37 °C, 120 rpm upon 48 h of incubation. Hyase was purified using salt precipitation, DEAE cellulose ion exchange, and Sephadex G-100 gel filtration chromatography. The enzyme was purified to 13-fold with 67.19% recovery of activity and 26.37 U/mg of specific activity. SDS-PAGE and zymography revealed it to be near to homogeneity showing a relative molecular weight of about 43 kDa that was confirmed by MALDI-TOF MS. This hyase was very active and stable at pH 7.0 and temperature 40 °C. The presence of metal ions Ca2+ and Mg2+ increased its activity while Zn2+ and Cu2+ severely inhibited it. Being stable at 2 M NaCl, hyase exhibited its halotolerant nature. This enzyme showed wide substrate specificity where hyaluronic acid (HA) was the best substrate. The kinetic studies revealed that Km and Vmax were 91.3 μg/mL and 306.2 μg/mL/min respectively. This is the first report of hyaluronidase from a halotolerant Brevibacterium spp. which can find applications under high salinity.As a member of the polyhydroxyalkanoate (PHAs) family, Poly(3-hydroxybutyrate) (PHB) has attracted much attention for a variety of medical applications because of its desirable properties such as high biocompatibility, nontoxic degradation products and high mechanical strength in comparison to other polymers in different fields including tissue engineering. There are different approaches such as making PHB alloy scaffolds, using PHB as a coating for ceramic-based scaffolds and producing composite scaffolds by using a mixture of PHB with ceramic particles utilized to improve hydrophobicity, degradation rate and brittleness. In this review, different applications of PHB, its alloys and composites in tissue engineering are explained based on the common methods of fabrication such as polymeric sponge replication, electrospinning and salt leaching. Liver CRIg (complement receptor of the immunoglobulin superfamily) macrophages play a critical role in filtering bacteria and their products from circulation. Translocation of microbiota-derived products from an impaired gut barrier contributes to the development of obesity-associated tissue inflammation and insulin resistance. However, the critical role of CRIg macrophages in clearing microbiota-derived products from the bloodstream in the context of obesity is largely unknown. We performed studies with CRIg , C3 , cGAS , and their wild-type littermate mice. The CRIg macrophage population and bacterial DNA abundance were examined in both mouse and human liver by either flow cytometric or immunohistochemistry analysis. Gut microbial DNA-containing extracellular vesicles (mEVs) were adoptively transferred into CRIg , C3 , or wild-type mice, and tissue inflammation and insulin sensitivity were measured in these mice. After coculture with gut mEVs, cellular insulin responses and cGAS/STING-mediateibute to the development of obesity-associated tissue inflammation and metabolic diseases.Much of the global increase in sugar intake is attributable to rising consumption of sugar-sweetened beverages (SSBs). Because people compensate poorly for liquid calories, SSB consumption increases total energy intake, raising the risk of harmful metabolic effects in addition to possible effects of sugars per se. Glucose and fructose, the constituent sugars i
