Antibacterial, antioxidant and enzyme inhibition activity capacities of Doronicum macrolepis (FREYN&SINT): An endemic plant from Turkey

In conclusion, the results suggest that, because of its bioactivity including the antioxidant, antimicrobial, and enzyme inhibition properties, the D. macrolepis can be accepted as a promising and natural source for the industrial applications. The present study is the first study, in which the bioactive components and the antioxidant, antimicrobial, and enzyme inhibition properties of endemic D. macrolepis plant were determined.

In this study, our aim was to evaluate ClO2 precursors, sodium chlorite and citric acid, under disparate but applicable conditions. First, we modeled production of ClO2 from the powdered precursors with three different masses, sample ID 1, 2, and 3, at room (18 °C) and refrigeration (4 °C) temperatures. Second, we investigated the effects of a water reservoir on ClO2 production. Third, we assessed collection method issues that may impact reported ClO2 values. Finally, we evaluated the precursor's efficacy against three common foodborne pathogens: Escherichia coli O157:H7, Listeria monocytogenes, and Salmonella ...

We provide a step-by-step guide on how epidemiologists can rank a number of control strategies based on their distribution of estimated benefits. We also explain how the expected utility model and decision maker’...

Given the strong antioxidant ability of resveratrol against oxidative stress, we evaluated the potential protective effects of resveratrol on myocardial injury induced by CIH. Twenty-four rats were divided into normal control group, CIH group, CIH plus resveratrol treated (CIH + Res) group, and resveratrol treated control (Res) group. We proved that CIH impa...

Traditional electrochemical immunosensors for pathogen detection involve electrode modification or samples adsorption on the electrode which affect the detection sensitivity and electrode reproducibility, thereby limiting their further application in POCT (point of care testing). We established a homogeneous ma...

In the algae, the role of individual metabolites (such as carotenoids, phenolic compounds, organic acids, and vitamins) and miRNAs that participate in plant’s defence are very poorly understood during stressful conditions. Therefore, in the present experiment, the model organism Chlam...

In this study, the antimicrobial activity of the essential oil of V. arborea was investigated in comparison with its major component α-bisabol. The antimicrobial activity was performed against Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 12692, Candida albicans (CA) INCQS 40006, Candida krusei (CK) INCQS 40095, Candida tropicalis (CT) INCQS 40042, and multiresistant bacterial strains Staphylococcus aureus 03 and Escherichia coli 08 by the microdilution method and direct contact modulation. The results showed that all strains were sensitive to the samples, except E. coli against the essential oil. Both the ...

In many countries, people with HIV are living longer than those with diabetes. This post will hopefully teach the basics of a complex disease and demystify some of the potential diseases you need to consider in those who are severely immunosuppressed. While trying to be comprehensive this post can not be exhaustive (as you can imagine any patient with ...

Rino Ragno A comprehensive study on essential oil and different solvent extracts of Sideritis romana L. subsp. purpurea (Tal. ex Benth.) Heywood (Lamiaceae) from Montenegro is reported. The gas chromatography-mass spectrometry analysis of the essential oil revealed a total of 43 components with bicyclogermacrene (23.8%), germacrene D (8%), (E)-caryophyllene (7.9%) and spathulenol (5.5%) as the major ones. Sesquiterpenoid group was found to be the most dominant one (64.8%), with 19.9% of the oxygenated forms. In the crude methanol extract of the investigated plant, obtained by Sohhlet exraction, the total phenol cont...
