Research ArticleOpen accessEvery word in the titleResponse Surface Optimized Ultrasonic Assisted Extraction of Total Flavonoids from Walnut Leaves and In Vitro Antibacterial ActivitiesYuanda Song, Aydin Berenjian, Han Wu et al.In this paper, the optimum extraction conditions of total flavonoids extracted from walnut leaves subjected to Ultrasonic Assisted Extraction (UAE) were optimized by Response Surface Methodology (RSM). The mathematical model showed the high coefficient of measurement (R2 = 0.9938) which indicated that this model could be used to guide the response surface methodology. The optimum extraction parameters for extracting flavonoids … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 4 · 24 Oct 2017 · 7,827 accessesView PDFCite
EditorialOpen accessEvery word in the titleAntibacterial Quorum-Sensing Molecules as Long Lasting Antibacterial DrugsAnanya Pavuluri, Yan Zhang, Shanzhi WangAntibacterial quorum-sensing molecules are a new type of antibacterial reagent that blocks bacterial communications and dampens virulence. These molecules are proposed to tackle the roots of drug resistance and to be long lasting, although more research should be done toward the effectiveness and resistance of these drugs. …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 1 · 26 Jan 2015 · 6,928 accessesView PDFCite
