Assessment of non-steroidal anti-inflammatory and analgesic pharmaceuticals in seawaters of North of Portugal: Occurrence and environmental risk
(Elsevier Science Bv, Amsterdam, 2015)
The occurrence of seven pharmaceuticals and two metabolites belonging to non-steroidal anti-inflammatory drugs and analgesics therapeutic classes was studied in seawaters. A total of 101 samples covering fourteen beaches ...
Leaching of polycyclic aromatic hydrocarbons from power plant lignite ash-influence of parameters important for environmental pollution
(Springer Heidelberg, Heidelberg, 2014)
Nikola Tesla B power plant (TENT B), located at the Sava River, in Obrenovac, 50 km west from the Serbian's capital, Belgrade, is the second largest coal-fired power plant in the country, consisting of two blocks, each of ...
Fish oil supplementation improved liver phospholipids fatty acid composition and parameters of oxidative stress in male wistar rats
(Wiley-Blackwell, Hoboken, 2012)
In the present study, we examined the effects of fish oil supplementation in 3 months old male Wistar rats on changes in plasma and liver lipid metabolism and oxidative stress parameters. Twenty Wistar rats were randomly ...
Advances in bipolar electrochemiluminescence for the detection of biorelevant molecular targets
(Current Opinion in Electrochemistry, 2019)
Bipolar electrochemistry (BPE) contrasts very much with conventional electrochemistry because it is based on the control of the solution potential instead of the working electrode potential. In a typical setup, a piece of ...
Unusual mode of reactivity of 2-alkylidene-4-oxothiazolidine S-oxides under the Pummerer reaction conditions
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
The reactivity of 2-alkylidene-4-oxothiazolidine S-oxides under the Pummerer reaction conditions, using Ac2O, TFAA, SOCl2 and SOBr2 as initiators, has been examined. Almost all reactions proceeded with absolute regioselectivity ...
An aldol approach to the enantioselective synthesis of (-)-oseltamivir phosphate
(Royal Soc Chemistry, Cambridge, 2011)
A formal asymmetric synthesis of the antiviral agent (-)-oseltamivir phosphate is achieved using two aldol reactions as key steps.
Complexation of amidated pectin with poly(itaconic acid) as a polycarboxylic polymer model compound
(Elsevier Sci Ltd, Oxford, 2011)
Complexes based on amidated pectin (AP) and poly(itaconic acid) (PIA) were prepared by casting films from solutions of AP and PIA in different ratios with the pectin amount ranging from 10% to 90% by mass. The complexes ...
A structure-property relationship study of bent-core mesogens with pyridine as the central unit
(Royal Soc Chemistry, Cambridge, 2014)
Three series of bent-core mesogens having pyridine as the central unit have been synthesized and characterized. A series of 2,6-diaminopyridine derivatives capable of forming inter- and intramolecular hydrogen bonds exhibit ...
Pattern recognition methods and multivariate image analysis in HPTLC fingerprinting of propolis extracts
(Wiley-Blackwell, Hoboken, 2014)
High-performance thin-layer chromatography (HPTLC) combined with image analysis and pattern recognition methods were used for fingerprinting and classification of 52 propolis samples collected from Serbia and one sample ...
A Useful Synthetic Equivalent of a Hydroxyacetone Enolate
(Amer Chemical Soc, Washington, 2011)
Indium promoted allyiation of carbonyl compounds with 4-(bromomethyl)-1,3-dioxol-2-one diastereoselectively affords and-alpha,beta-dihydroxyketones, protected as enol carbonates. These initial products can be deprotected ...
