Antibiotic delivery by liposomes from prokaryotic microorganisms: Similia cum similis works better.

Eur. J. Pharm. Biopharm. 94 , 411-8, (2015)

To date the effectiveness of antibiotics is undermined by microbial resistance, threatening public health worldwide. Enhancing the efficacy of the current antibiotic arsenal is an alternative strategy. The administration of antimicrobials encapsulated in nano...

Occurrence of perfluorinated alkyl substances in sediment from estuarine and coastal areas of the East China Sea.

Environ. Sci. Pollut. Res. Int. 22(3) , 1662-9, (2015)

Perfluorinated alkyl substances (PFAS) have drawn much attention due to their environmental persistence, ubiquitous existence, and bioaccumulation potential. The occurrence and spatial variation of PFAS were investigated through collection of riverine and mar...

Sources and fate of perfluorinated compounds in the aqueous environment and in drinking water of a highly urbanized and industrialized area in Italy.

J. Hazard. Mater. 282 , 51-60, (2014)

Perfluorinated substances are listed among emerging contaminants because they are globally distributed, environmentally persistent, bioaccumulative and potentially harmful. In a three-year monitoring campaign (2010-2013) we investigated the occurrence, source...

Determination of perfluorinated alkyl acids in corn, popcorn and popcorn bags before and after cooking by focused ultrasound solid-liquid extraction, liquid chromatography and quadrupole-time of flight mass spectrometry.

J. Chromatogr. A. 1355 , 211-8, (2014)

An analytical method is proposed to determine ten perfluorinated alkyl acids (PFAAs) [nine perfluorocarboxylic acids (PFCAs) and perfluorooctane sulfonate (PFOS)] in corn, popcorn and microwave popcorn packaging by focused ultrasound solid-liquid extraction (...

Development and co-validation of porcine insulin certified reference material by high-performance liquid chromatography-isotope dilution mass spectrometry.

Anal. Bioanal. Chem 407(11) , 3125-35, (2015)

This article concerns the development and co-validation of a porcine insulin (pINS) certified reference material (CRM) produced by the National Institute of Metrology, People's Republic of China. Each CRM unit contained about 15 mg of purified solid pINS. The...

Transition metal complexes bearing NHC ligands substituted with secondary polyfluoroalkyl groups.

Dalton Trans. 44 , 19663-73, (2015)

Using three different approaches, racemic 1-(perfluoroalkyl)ethylamines were synthesized from perfluoroalkyl iodides or perfluoroalkanoic acids, and further transformed to the corresponding N,N'-disubstituted ethane-1,2-diimines and ethane-1,2-diamines as mix...

Online background cleanup followed by high-performance liquid chromatography with tandem mass spectrometry for the analysis of perfluorinated compounds in human blood.

J. Sep. Sci. 38(2) , 247-53, (2015)

In this study, a novel method for the analysis of perfluorinated compounds in whole blood has been developed and validated. The method was developed by using a conventional reversed-phase C18 column as a trapping column for the elimination of background conta...

Spatiotemporal distribution and mass loadings of perfluoroalkyl substances in the Yangtze River of China.

Sci. Total Environ. 493 , 580-7, (2014)

A systematic investigation into contamination profiles of eighteen perfluoroalkyl substances (PFASs) in both surface water and sediments of Yangtze River was carried out by using high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) in ...

Heat-activated persulfate oxidation of PFOA, 6:2 fluorotelomer sulfonate, and PFOS under conditions suitable for in-situ groundwater remediation.

Chemosphere 145 , 376-83, (2016)

PFOA (perfluorooctanoic acid) oxidation (0.121-6.04 μM) by heat-activated persulfate was evaluated at 20-60 °C with 4.2-84 mM [Formula: see text] and in the presence of soluble fuel components to assess feasibility for in-situ remediation of groundwater. 6:2 ...
