Research ArticleOpen accessIn the abstractHigh Concentrations of Glucose can Activate or Inhibit Human Erythrocyte Aminolevulinate Dehydratase in vitro Depending Exposure TimeJ. C. Soares, D. Gabriel, V. Folmer et al.Hyperglycemia can cause oxidative stress and inactivate susceptible enzymes. In the present investigation we examined whether short-term incubations (24 or 48 h) with high concentrations of glucose (10-200 mmol L-1) inhibit ALA-D from human erythrocytes. Incubations of erythrocytes for 24 h with glucose (10 up to 40 mmol L-1) resulted in an increase of δ-ALA-D activity (P<0,001). Incubations of erythrocytes … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 4 · 31 Dec 2006 · 6,686 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIn vitro Effects of Beet Root Juice on Stimulated and Unstimulated Peripheral Blood Mononuclear CellsChristiana Winkler, Barbara Wirleitner, Katharina Schroecksnadel et al.Intake of fruits and vegetables rich in antioxidants is suggested to reduce the incidence of cancer and coronary heart disease in humans. Exceptional antioxidant activity of beet root extracts has been reported. Likewise in animal models, e.g., extracts of red beetroot Beta vulgaris var. rubra revealed significant tumor inhibitory effects. Red beetroot concentrate is universally permitted as a food ingredient. … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 4 · 31 Dec 2005 · 9,522 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOptimization of Cellulase-Assisted Extraction of Total Flavonoids from Corn Bract and Evaluation of Antioxidant and Antibacterial AactivitiesYang Zhang, Jing Lu, Leijie Ben et al.Corn bract is a corn-based agricultural waste material that distributed worldwide. In present work, response surface methodology was applied to optimize the cellulase-assisted extraction of Total Flavonoids from Corn Bract (TFCB), the in vitro antioxidant and antibacterial as well as the in vivo antioxidant activities of TFCB were investigated. Results showed that the optimal conditions for TFCB extraction were as … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 2 · 18 May 2019 · 8,501 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPhenotypic ESBL Detection in Acinetobacter baumannii: A Real ChallengeGeetanjali M. Litake, Vikram S. Ghole, Krishna B. Niphadkar, Suresh G. JoshiClinical Laboratory Standards Institute (CLSI) recommends two-step approach for extended-spectrum-β-lactamase (ESBL) detection which includes the screening of recommended agents and the phenotypic confirmation of ESBL using a combination of screening agent and β-lactamase inhibitor. To investigate this approach, we screened 145 β-lactamase-producing Acinetobacter baumannii isolates for ESBL from tracheal secretions using double disk synergy test (DDST) and phenotypic confirmatory disc … …American Journal of Infectious Diseases, Vol. 11, Issue 3 · 19 Oct 2015 · 7,771 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPOTENCY OF HONEY AS ANTIBACTERIAL AGENT AGAINST MULTIPLE ANTIBIOTIC RESISTANT PATHOGENS EVALUATED BY DIFFERENT METHODSMohamed Mustafa Aween, Zaiton Hassan, Nur Huda-Faujani et al.Honey is rich with complex natural components which could be useful as antibacterial agents or as preservative. Honey contains high concentration of sugars, low amount of water, high osmolality and often dark colour which influence its antibacterial activity. Disc diffusion, well method, micro dilution assay are methods commonly used to determine the antibacterial activity of honey. In this study, microtiter … …American Journal of Applied Sciences, Vol. 11, Issue 10 · 1 Dec 2014 · 6,564 accessesView PDF Cite

Research ArticleOpen accessIn the abstractLIQUID AND VAPOUR PHASE ANTIBACTERIAL ACTIVITY OF EUCALYPTUS GLOBULUS ESSENTIAL OIL = SUSCEPTIBILITY OF SELECTED RESPIRATORY TRACT PATHOGENSBoukhatem Mohamed Nadjib, Ferhat Mohamed Amine, Kameli Abdelkrim et al.Essential Oils (EO) produced by medicinal plants have been traditionally used for respiratory tract infections and are used nowadays as ethical medicines for colds. Although several studies of Eucalyptus Globulus Labill. Essential Oil (EGEO) have been reported, there are no reports describing vapour activity of EGEO against bacterial respiratory tract pathogens.
