An alkalophilic bacterium, Bacillus cereus produced an extracellular alkaline protease, which was found to be active at high temperature and pH range, suitable for commercial laundry detergents. B. cereus protease was partitioned in different aqueous two-phase systems such as PEG/dextran, PEG/potassium phosphate, PEG/sodium citrate, PEG/magnesium sulphate and PEG/sodium dihydrogen phosphate and...

Introduction Stilbenoid compounds have been described to anti-inflammatory properties in animal models vivo , and shown inhibit Ca2+-influx through the transient receptor potential ankyrin 1 (TrpA1). Methods To study how stilbenoid affect inflammatory signaling we utilized fruit fly, Drosophila melanogaster as a model system. induce intestinal inflammation fed flies with irritant dextran sodium...

Several bacterial pathogens including Neisseria gonorrhoeae bind the human serum glycoprotein vitronectin. We aimed at defining the gonococcal receptor for vitronectin. Ligand blots demonstrated that vitronectin bound specifically to the heparin-binding outer-membrane protein OpaA, but that coating OpaA with the sulphated polysaccharide heparin was required for the interaction to occur. Bound v...

The aim of this study was to investigate the structural characteristics and antioxidant activities of soy protein isolate- (SPI-) dextran conjugates obtained by TiO2 photocatalysis treatment. Results revealed that the UV-vis absorption and the fluorescence intensity increased as the photocatalytic power increased (P < 0.05). Higher photocatalytic power could promote the extent of glycation and ...

The dextran sodium sulphate (DSS) induced colitis in mice was used as a experimental model to study the contractility of murine longitudinal colonic smooth muscle during inflammation. Smooth muscle segments of proximal, middle and distal colon were mounted in organ baths. Smooth muscle contraction was induced by carbachol showing an aboral increase in activity, whereas in the inflamed middle co...
