Hyperatomarin, an antibacterial prenylated phloroglucinol from Hypericum atomarium ssp degenii
(American Chemical Society (ACS), 2003)
As shown by quantitative 1H NMR measurements, a lipophilic extract of the aerial parts of Hypericum atomarium ssp. degenii contained a high percentage (3.1% per weight of dried plant material) of a prenylated phloroglucinol ...
Water-soluble main ions in precipitation over the southeastern Adriatic region: chemical composition and long-range transport
(Springer Heidelberg, Heidelberg, 2010)
Precipitation samples collected from 1995 to 2000 at meteorological station in the eastern outskirts of Herceg Novi (Montenegro) were analysed on Na(+), K(+), Mg(2+), Ca(2+), Cl(-), SO(4) (2-), NO(3) (-) and NH(4) (+). ...
Antioxidant properties of grape seed extract on human lymphocyte oxidative defence
(Georg Thieme Verlag Kg, Stuttgart, 2008)
The distribution of polyphenolic compounds in a grape (Vitis vinifera) seed extract (GSE) was determined using LC/ESI-TOF MS, HPLC/DAD, and C-13-NMR. The 17 identified compounds comprised gallic and protocatechuic acid, ...
Coordination and redox interactions of β-lactam antibiotics with Cu2+ in physiological settings and the impact on antibacterial activity
(Elsevier, 2018)
An increase in the copper pool in body fluids has been related to a number of pathological conditions, including infections. Copper ions may affect antibiotics via the formation of coordination bonds and/or redox reactions. ...
A QSAR study of acute toxicity of N-substituted fluoroacetamides to rats
(Oxford : Pergamon-Elsevier Science Ltd, 2006)
Acute toxicity in vivo toward rats, of nineteen N-alkyl and N-cycloalkyl fluorocetamides [F-CH2-C(O)-NH-R] was correlated with their structure-dependent properties. Used descriptors are: molecular weights (M-w) and heat ...
Surface modification of polyethylene by Ag+ and Au+ ion implantation observed by phase imaging atomic force microscopy
(Elsevier, 2012)
High density polyethylene (HDPE) has been modified by Ag+ and Au+ ion implantation with the energy of 60 and 200 keV, respectively. The doses of implanted silver and gold ions were as follows: 1 x 10(15), 5 x 10(15) and 1 ...
Classification of stacking interaction geometries of terpyridyl square-planar complexes in crystal structures
(Royal Soc Chemistry, Cambridge, 2010)
Stacking interactions of terpyridyl square-planar complexes in crystal structures were studied analyzing data from the Cambridge Structural Database. In most of the crystal structures, two terpyridyl complexes were oriented ...
Antioxidative activities and chemical characterization of polysaccharides extracted from the basidiomycete Schizophyllum commune
(Elsevier, 2011)
Antioxidant properties properties of hot water extract (HWE), hot water extracted polysaccharides (HWP) and hot alkali extracted polysaccharides (HWAE) were obtained from fruiting bodies of the wild basidiomycete Schizophyllum ...
Study of flow and pressure field in microchannels with various cross-section areas
(Elsevier, 2010)
In this work a micro-flow sensor integrated in the bottom surface of a rectangular microchannel is used in order to evaluate simultaneously both the flow velocity and the pressure in various micro-flow conditions. In this ...
Pharmacological evaluation of selected arylpiperazines with atypical antipsychotic potential
(Elsevier, 2004)
Six active compounds, among previously synthesized and screened arylpiperazines, were selected and evaluated for the binding affinity to rat dopamine, serotonin and α 1 receptors. Two compounds with benztriazole group had ...
