Abstract The ultra-high pressure-assisted extraction (UHPE) of total phenols from Eucommia ulmoides leaves (TPEU) was optimized and its antioxidant activity on seed oil studied. effects UHPE pressure, time, ethanol concentration the yield TPEU were examined by response surface methodology. In addition, added to oil, (acid value, peroxide value) during storage optimal conditions as follows: 406 ...

A drug can affect the activity of other drugs, when administered together, in both synergistic or antagonistic ways. In one hand synergistic effects lead to improved therapeutic outcomes, antagonistic consequences can be life-threatening, leading to increased healthcare cost, or may even cause death. Thus, identification of unknown drug-drug interaction (DDI) is an important concern for efficie...

background: increasing worldwide contamination with hydrocarbons has urged environmental remediation using biological agents such as bacteria. our goal here was to study the phylogenetic relationship of two crude oil degrader bacteria and investigation of their ability to degrade hydrocarbons. materials and methods: phylogenetic relationship of isolates was determined using morphological and bi...

background and objectives: the selection of alternative treatment options with antibiotic combinations may be used for successful managing of multidrug-resistant acinetobacter baumannii . the aim of this study was to determine the synergistic effects of ampicillin-sulbactam combined with either levofloxacin or tigecycline against mdr a. baumannii. materials and methods: a total 124 of a.baumann...

The studies reported here focus on the extraction of La(III), Eu(III), and Yb(III) by chelating hexadentate 3-alkoxy-2-hydroxyphenyl substituted diimine ligands using system Ln(NO3)3–Zn(NO3)2–NaNO3–buffer–H2O/diimine-n-caprylic acid–CHCl3. Significant synergistic enhancement has been observed for Ln(III) from nitrate media in presence Zn(II) n-caprylic acid. These effects can be interpreted sel...
