Bioactive Pentacyclic Triterpene Ester Derivatives from Alnus viridis ssp viridis Bark
(American Chemical Society (ACS), 2017)
Seven derivatives of pentacyclic triterpene acids (1-7) were isolated from the bark of Alnus viridis ssp. viridis using a combination of column chromatography and semipreparative HPLC. Compounds 1-3, 6, and 7 were determined ...
Petrographical and organic geochemical study of the Kovin lignite deposit, Serbia
(Elsevier, 2016)
The origin of the organic matter (OM) and the characteristics of the depositional environment of lignites from the Upper Miocene Kovin deposit (hosting three coal seams) of Serbia were evaluated based on petrographic data, ...
Composition, antifungal and antioxidant properties of Hyssopus officinalis L. subsp pilifer (Pant.) Murb. essential oil and deodorized extracts
(Elsevier, 2013)
The aim of the study was to investigate the chemical composition of Hyssopus officinalis L subsp. pilifer (Pant.) Murb. essential oil (EO) and deodorized extracts (DE) and to evaluate their potential antifungal and antioxidant ...
Hydrogel based on chitosan, itaconic acid and methacrylic acid as adsorbent of Cd2+ ions from aqueous solution
(Elsevier Science Sa, Lausanne, 2010)
A hydrogel has been synthesized by ionic crosslinking of chitosan (Ch) with itaconic acid (IA), followed by a free radical polymerization and crosslinking of Ch/IA network by adding methacrylic acid and the crosslinker. ...
Theoretical study of nitrodibenzofurans: A possible relationship between molecular properties and mutagenic activity
(Elsevier, 2016)
In this study we present a theoretical investigation of the molecular properties of nitrodibenzofurans (NDFs) and dinitrodibenzofurans (DNDFs) and their relation to mutagenic activity. Equilibrium geometries, relative ...
Optimization of extraction of stinging nettle leaf phenolic compounds using response surface methodology
(Elsevier, 2015)
A full three level factorial design was implemented for optimization of extraction parameters in order to maximize total phenolic (TP) yield from stinging nettle leaf. Factors considered were percentage of methanol in ...
Synthesis and characterization of a new type of levan-graft-polystyrene copolymer
(Elsevier Sci Ltd, Oxford, 2016)
Novel macromolecular graft copolymers were synthesized by reaction of the hydroxyl groups of the microbial polysaccharide levan, produced using Bacillus licheniformis, with polystyrene (Lev-g-PS). Synthesis was performed ...
Bacillus amyloliquefaciens laccase - From soil bacteria to recombinant enzyme for wastewater decolorization
(Elsevier Sci Ltd, Oxford, 2013)
One hundred wild type strains of Bacillus sp. were isolated from industrial and agricultural soil across Serbia and screened for laccase activity. Three strains showed high laccase activity temperature optimum of 65 and ...
The HPA axis and ethanol: a synthesis of mathematical modelling and experimental observations
(Wiley, Hoboken, 2017)
Stress and alcohol use are interrelatedstress contributes to the initiation and upholding of alcohol use and alcohol use alters the way we perceive and respond to stress. Intricate mechanisms through which ethanol alters ...
Sorption of zinc by novel pH-sensitive hydrogels based on chitosan, itaconic acid and methacrylic acid
(Elsevier, 2011)
Novel pH-sensitive hydrogels based on chitosan, itaconic acid and methacrylic acid were applied as adsorbents for the removal of Zn(2+) ions from aqueous solution. In batch tests, the influence of solution pH, contact time, ...
