Fifty samples of honey collected from local markets of Portugal and Spain during year 2002 were analyzed for 42 organochlorine, carbamate, and organophosphorus pesticide residues. An analytical procedure based on solid-phase extraction with octadecyl sorbent followed by gas chromatography-mass spectrometry (GC-MS), for organochlorines, and by liquid chromatography-atmospheric pressure chemical ...

Mutations in the FGFR3 gene cause the phenotypic spectrum of FGFR3 chondrodysplasias ranging from lethal forms to the milder phenotype seen in hypochondroplasia (Hch). The p.N540K mutation in the FGFR3 gene occurs in ∼70% of individuals with Hch, and nearly 30% of individuals with the Hch phenotype have no mutations in the FGFR3, which suggests genetic heterogeneity. The identification of a sev...

The γ isomer of hexachlorocyclohexane (HCH), also known as lindane, is a carcinogenic persistent organic pollutant. Lindane was used worldwide an agricultural insecticide. Legacy soil and groundwater contamination with lindane other HCH isomers still big concern. biotic reductive dechlorination to nondesirable toxic lower chlorinated compounds such monochlorobenzene (MCB) benzene, among others,...

This article describes the development of the Community Connections Program (CCP), a community care team, within a health care home (HCH), as a short-term, intensive, team-based service planning and coordination program for older adults with multiple chronic health conditions. Three proven approaches were combined to support patient's self-management, nurse care coordination, the Wraparound pro...

The absolute configuration of salicortin, HCH-salicortin and tremulacin, isolated from leaves of Populus trichocarpa × deltoides Beaupré, was determined by comparing spectroscopic data of these compounds with those of idescarpin, isolated from leaves of Idesia polycarpa. All compounds were characterized by nuclear magnetic resonance spectroscopy, high-resolution mass spectrometry, and circular ...

The current study evaluated certain emerging contaminants in the Susurluk sub-basin, which is under significant anthropogenic pollution pressure. Polychlorinated Biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), organochlorine insecticides, and microplastics were investigated from both surface sediment samples collected dry wet seasons. In Kocaçay river reaching Marmara Sea, γ-HCH β-HCH...

Papers and published reports investigating the presence of pesticides in rainfall in Europe were reviewed. Approximately half of the compounds that were analysed for were detected. For those detected, most concentrations were below about 100 ng/l, but larger concentrations, up to a few thousand nanograms per litre, were detected occasionally at most monitoring sites. The most frequently detecte...

The present study is undertaken to predict the three dimensional structure of γ-Hexachlorocyclohexane dehydrochlorinase (linA) in Sphingomonas paucimobilis UT26. γ-Hexachlorocyclohexane dehydrochlorinase (linA) catalyzes the initial steps in the biotransformation of the important insecticide γhexachlorocyclohexane (γ-HCH) by the soil bacterium Sphingomonas paucimobilisUT26. Stereo chemical anal...
