Antitumor effects of a natural anthracycline analog (Aloin) involve altered activity of antioxidant enzymes in HeLaS3 cells
(Taylor & Francis Inc, Philadelphia, 2007)
The anti proliferative and cytotoxic potential of the natural anthracycline aloin from Aloe vera was tested on human uterine carcinoma HeLaS3 cells. Aloin showed a pronounced antiproliferative effect at physiological ...
Optical fibers with composite magnetic coating
(Elsevier, 2002)
The goal of these investigations was to define the process parameters that enable the formation of a composite coating with the most uniform thickness on an optical fiber. The composite coating was obtained by drawing the ...
Further sesquiterpene lactones from Anthemis carpatica
(Pergamon, 2000)
A new germacranolide, (E)-1α, 10β-epoxy-3β-acetoxy-6α-hydroxygermacra-4,11(13)-dien-12,8α-o lide, together with nine new highly oxygenated guaiadien-12,6α-olides of anthemolide, and cumambrin type were identified in the ...
A comparative study of the electrochemical properties of carbon nanotubes and carbon black
(Elsevier, 2009)
Two samples of commercial multi-walled carbon nanotubes (Sigma-Aldrich and Sun Nanotech) and a sample of carbon black (Vulcan XC-72R) were investigated in raw state and after the activation in nitric and sulfuric acid by ...
Organobentonite as efficient textile dye sorbent
(Wiley-V C H Verlag Gmbh, Weinheim, 2008)
Domestic bentonite clay was modified using cationic surfactant - hexadecyltrimethylammonium bromide (HDTMA-bromide) in order to obtain more efficient sorbent. Removal of Acid Orange 10 from aqueous solution at different ...
Evaluation of Hypericum perforatum oil extracts for an antiinflammatory and gastroprotective activity in rats
(Phytotherapy Research, 2009)
Oil extracts of Hypericum perforatum L. (Oleum Hyperici) were prepared in three different ways according to the prescriptions from traditional medicine. Variability of constituents and biological activity were evaluated ...
The influence of heat treatment and finishing on the mechanical and dielectric properties of glass fabric-epoxy resin laminar composites
(Springer Netherlands, 2003)
The aim of this investigation was to define the optimum conditions of obtaining glass fabric - epoxy resin laminar composites with mechanical and dielectric properties that satisfy the quality needed for production of ...
Biomarker distributions as indicators for the depositional environment of lacustrine sediments in the Valjevo-Mionica basin (Serbia)
(Elsevier Gmbh, Urban & Fischer Verlag, Jena, 2008)
In this study, the molecular composition and biomarker distribution of lacustrine sediments from Val-1 drillhole in the central zone of the western part of the Valjevo-Mionica basin were investigated at depth interval of ...
The electrocatalytic properties of the oxides of noble metals in the electrooxidation of methanol and formic acid
(Elsevier, 2001)
The electrooxidation of 0.25 M methanol as well as of 0.25 M formic acid was examined on oxides formed on the Au(111) electrode surface in 0.5 M H2SO4 and 0.5 M NaHCO3 at a sweep rate of 0.5 mV/s. In the case of methanol, ...
Melt Rheology of Aliphatic Hyperbranched Polyesters
(Wiley, 2009)
Rheological behavior in melt of aliphatic hyperbranched polyesters (AHBP), synthesized using pseudo-one-step and one-step procedure, was investigated in this work. Three commercially available AHBP were also examined. ...
