In this paper, a micro-fluidic optimized process for the continuous flow synthesis of azo compounds is presented. The continuous flow synthesis of Sudan II azo dye was used as a model reaction for the study. At found optimal azo coupling reaction temperature and pH an investigation of the optimum flow rates of the reactants for the diazotization and azo coupling reactions in Little Things Facto...

X-ray absorption spectra of a number of organic iodine and bromine compounds of biological relevance, as well as of a series of iodine compounds with different oxidation states, have been measured. The iodine K-edge spectra (XANES) are found to be relatively featureless but the position of the edge is found to be sensitive to formal valence (among other factors), and the edge shape to the numbe...

background: recurrent aphthous stomatitis (ras) is the most common painful ulcers of oral mucosal which can cause many sufferings. treatment of ras often includes administration of corticosteroids, analgesics and regulators of the immune system. however, considering the side effects of these medications, even their topical application must be done with caution. alum is used in traditional medic...

extensive research in the last decade has defined that most chronic diseases display dysregulation of multiple cell signaling pathways that have been linked to inflammation. neuroinflammation is reaction of living nervous tissue to injury. it may be initiated in response to neurological disease. including infection, traumatic brain injury, toxic metabolites and autoimmunity. the natural compoun...

background scrophularia striata (scrophulariaceae family) is an herbaceous plant that is traditionally used for treatment of microbial infections. objectives antimicrobial and antioxidant activity of different extracts (methanolic, ethanolic, aqueous and ethyl acetate) from s. striata aerial parts was evaluated. materials and methods the antimicrobial activity of different extracts from s. stri...
