Purification and characterisation of Saccharomyces cerevisiae external invertase isoforms
(Elsevier Sci Ltd, Oxford, 2010)
Four external invertase isoforms (EINV1, EINV2, EINV3 and EINV4) from Saccharomyces cerevisiae were highly purified by isoelectric precipitation, ethanol precipitation, ion-exchange on QAE-Sephadex and gel filtration using ...
Chemical stability of the peroxide bond enables diversified synthesis of potent tetraoxane antimalarials
(American Chemical Society (ACS), 2008)
Of 17 prepared 1,2,4,5-tetraoxacyclohexanes stable to reductive and acidic conditions, 3 of them were more active than artemisinin against CQ and MFQ resistant strain TM91C235 and all compounds were more active in vitro ...
On the role of working fluid properties in Organic Rankine Cycle performance
(Oxford : Pergamon-Elsevier Science Ltd, 2012)
The performance of ORC systems strongly depends on working fluid properties. We explore the relationships between working fluid properties and ORC common economic and thermodynamic performance criteria from a theoretical ...
Arylpiperazine-mediated activation of Akt protects SH-SY5Y neuroblastoma cells from 6-hydroxydopamine-induced apoptotic and autophagic death
(Oxford : Pergamon-Elsevier Science Ltd, 2013)
We investigated the ability of 19 recently synthesized arylpiperazine compounds to protect human SH-SY5Y neuroblastoma cells from the neurotoxin 6-hydroxydopamine (6-OHDA). The compound with the most potent neuroprotective ...
Open circuit potentials of metallic chromium and austenitic 304 stainless steel in aqueous sulphuric acid solution and the influence of chloride ions on them
(Corrosion Science, 2008)
Open circuit potential measurements and cyclic voltammetry of chromium and 304 stainless steel in deaerated aqueous H2SO4 solution of pH 1, without and containing NaCl in the concentration range 1-4 M revealed that chromium ...
Electrochemical and capacitive properties of thin-layer carbon black electrodes
(Journal of Power Sources, 2008)
Electrochemical properties and porous-structure-dependent capacitive ability of commercial carbon blacks, Black Pearls 2000® (BP) and Vulcan® XC 72R (XC), were investigated in H2SO4 solution by cyclic voltammetry (CV) and ...
Sol gel processed thin-layer ruthenium oxide/carbon black supercapacitors: A revelation of the energy storage issues
(Elsevier, 2010)
Hydrous ruthenium oxide/carbon black nanocomposites were prepared by impregnation of the carbon blacks by differently aged inorganic RuO2 sols, i.e. of different particle size. Commercial Black Pearls 2000 (R) (BP) and ...
Supercritical carbon dioxide extraction of antioxidant fractions from selected Lamiaceae herbs and their antioxidant capacity
(Elsevier Sci Ltd, Oxford, 2010)
Antioxidant fractions from four herb spices belonging to the Lamiaceae family: rosemary (Rosmarinus officinalis), sage (Salvia officinalis), thyme (Thymus vulgaris) and hyssop (Hyssop officinalis) were isolated using ...
Antioxidative and immunomodulating activities of polysaccharide extracts of the medicinal mushrooms Agaricus bisporus, Agaricus brasiliensis, Ganoderma lucidum and Phellinus linteus
(Elsevier Sci Ltd, Oxford, 2011)
Partially purified polysaccharides were obtained from four medicinal mushroom species, Agaricus bisporus, Agaricus brasiliensis, Phellinus linteus and Ganoderma lucidum by hot water extraction, followed by ethanol ...
Electrochemical behavior of immobilized hemoglobin in alkaline solution
(Elsevier, 2017)
Glassy carbon electrode was modified with different synthesized hybrid clay-based materials and tested in alkaline solution with and without H2O2. The hybrid materials were obtained by immobilizing hemoglobin (Hb) on acid ...
