Further in vitro Evaluation of Antimicrobial Activity of the Marine Sesquiterpene Hydroquinone Avarol
(Bentham Science Publ Ltd, Sharjah, 2014)
This work extends in vitro screening of antimicrobial activity of the sesquiterpene hydroquinone avarol, a main secondary metabolite of the Mediterranean sponge species Dysidea avara. The antimicrobial activity was in part ...
A universal fluid cell for the imaging of biological specimens in the atomic force microscope
(Wiley-Blackwell, Hoboken, 2013)
Recently, atomic force microscope (AFM) manufacturers have begun producing instruments specifically designed to image biological specimens. In most instances, they are integrated with an inverted optical microscope, which ...
Co(III) complexes of (1,3-selenazol-2-yl)hydrazones and their sulphur analogues
(Royal Soc Chemistry, Cambridge, 2017)
The first Co(III) complexes with (1,3-selenazol-2-yl)hydrazones as an unexplored class of ligands were prepared and characterized by NMR spectroscopy and X-ray diffraction analysis. The novel ligands act as NNN tridentate ...
Phenolic natural products of the wines obtained from three new Merlot clone candidates
(Taylor & Francis Ltd, Abingdon, 2016)
This work aimed to evaluate the total contents of polyphenolics (the Ribereau-Gayon-Maurie procedure), anthocyanins (using pH differential method) and tannins (the Negre procedure) as well as the content of phenolic acids ...
ZnTiO3 Ceramic Nanopowder Microstructure Changes During Compaction
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2013)
ZnTiO3 nanopowder as a constitutive component in compact production was primarily characterised. Scanning electron micrographs of as received powder were recorded. Mercury porosimetry and nitrogen adsorption were also ...
Potential antioxidant activity of the moss Bryum moravicum
(Taylor & Francis Ltd, Abingdon, 2013)
A limited number of mosses has ever been studied regarding antioxidant activity among which only a few are European species. As a part of our ongoing screening of new promising bryophyte resources of natural antioxidants, ...
Stabilization of N,N '-bis(3-methylphenyl)-N,N '-bis(phenyl)benzidine thin film morphology with UV light
(Elsevier Science Sa, Lausanne, 2014)
Owing to their low glass transition temperature, T-g, amorphous thin films of N,N'-bis(3-methylphenyl)-N,N'bis(phenyl)benzidine (TPD) undergo morphological changes even at room temperature. It has been noticed previously ...
Spectral sensitivity of the electroretinogram b-wave in dark-adapted Prussian carp (Carassius gibelio Bloch, 1782)
(Springer, Dordrecht, 2014)
One of the purposes of this study was to examine whether b-wave measurements can be used in the evaluation of scotopic spectral sensitivity in Prussian carp measurements when the eyes were surgically deprived of cornea, ...
V-51 NMR investigation of cell-associated vanadate species in Phycomyces blakesleeanus mycelium
(Elsevier Science Bv, Amsterdam, 2016)
V-51 NMR spectroscopy was used for detection and identification of cell-associated vanadate (V5+) species after exposure of Phycomyces blakesleeanus mycelium, in exponential phase of growth, to sodium orthovanadate. Complete ...
Anti-hydroxyl radical activity, redox potential and anti-AChE activity of Amanita strobiliformis polysaccharide extract
(Taylor & Francis Ltd, Abingdon, 2019)
This study outlines antioxidant and anti-AChE activities of the polysaccharide (PSH) extract from the mushroom species Amanita strobiliformis. Both the presence of alpha and ss glucans within the aforementioned extract was ...
