Gentiana lutea Extracts and their Constituents as Inhibitors of Synaptosomal Ecto-NTPDase
(Asian Network Scientific Information-Ansinet, Faisalabad, 2016)
The extracellular nucleotides act as neurotransmitters and signaling molecules in CNS, binding to a P2X and P2Y receptors. Their concentration regulates a cascade of membrane ecto enzymes, including the ecto-nucleotide ...
Comparative study of the phenolic composition of seeds from grapes cv cardinal and alphonse lavallee during last month of ripening
(Chiriotti Editori, 2012)
During the last month of ripening, the phenolic composition of seeds from two widely distributed table grapes, cv Cardinal and Alphonse Lavallee, was determined by HPLC/DAD/ESI/MS. Besides, the concentrations of nutrients ...
Synthesis, characterization and biological activities of N-heteroaromatic hydrazones and their complexes with Pd(II), Pt(II) and Cd(II)
(Springer, Dordrecht, 2010)
Condensation derivatives of ethyl hydrazinoacetate with 2-formylpyridine and quinoline-2-carboxaldehyde were synthesized. Pd(II), Pt(II) and Cd(II) complexes with the 2-formylpyridine derivative and a Cd(II) complex with ...
Comparative Spectroscopic Characterization of the Basic and the Higher Fullerenes
(Taylor & Francis Inc, Philadelphia, 2013)
The basic C-60 and C-70, and the higher fullerenes, mainly C-76 and C-84, were extracted by original procedures, with p-xylene and the mixture of xylenes from the samples of initial carbon soot, produced in electrical arc. ...
Do altered activities of superoxide dismutases and the level of NF-κB modulate the effects of gamma radiation in HeLaS3 cells?
(Serbian Chemical Society, 2007)
Most experimental models, including cell culture studies, have demonstrated that over-expression of manganese superoxide dismutase (MnSOD) in cells bearing a carcinoma phenotype has anti-proliferative and tumour suppression ...
Spectroscopic properties and antimicrobial activity of dioxomolybdenum(VI) complexes with heterocyclic S,S'-ligands / Spektroskopska svojstva i antimikrobna aktivnost dioksomolibden(VI) kompleksa sa heterocikličnim S,S'-ligandima
(Srpsko hemijsko društvo, Beograd, 2012)
Five new dioxomolybdenum(VI) complexes of the general formula [MoO2(Rdtc)2], 1-5, where Rdtc- refer to piperidine (Pipdtc), 4-morpholine (Morphdtc), 4-thiomorpholine (Timdtc), piperazine (Pzdtc) or N-methylpiperazine ...
Preparation and characterization of two types of covalently immobilized amyloglucosidase / Dobijanje i karakterizacija dva tipa imobilizovane amiloglukozidaze
(Serbian Chemical Soc, Belgrade, 2005)
Amyloglucosidase from A. niger was covalently immobilized onto poly( GMA-co-EGDMA) by the glutaraldehyde and periodate method. The immobilization of amyloglucosidase after periodate oxidation gave a preparate with the ...
Evaluation of heavy metal contamination in sediments using the method of total digestion and determination of the binding forms-Tisa River Basin, Serbia
(Taylor and Francis Inc., 2010)
This paper describes an approach for the evaluation of metal contamination in sediment, using the determination of binding forms of elements (sequential extraction method), the total element content (digestion method), as ...
Thermal properties of poly(urethane-ester-siloxane)s based on hyperbranched polyester
(Maik Nauka/Interperiodica/Springer, New York, 2011)
Novel polyurethanes (PUs) were synthesized using hydroxy-terminated hyperbranched polyester (BH-20) and 4,4'-methylenediphenyl diisocyanate (MDI) as hard segments and hydroxy-terminated ethylene oxide-poly(dimethylsiloxa ...
Bacterially generated Fe2(SO4)3 from pyrite, as a leaching agent for heavy metals from lignite ash / Bakterijski generisani Fe2(SO4)3 iz pirita kao agens za luženje elektrofilterskog pepela termoelektrane iz procesa sagorevanja lignita
(Serbian Chemical Society, 2007)
Investigations of heavy metals from lignite ash, which is a coal combustion by-product, have for years been very interesting from different aspects of environmental protection. In this study, the possibility of microbiological ...
