The Tagus is the longest Iberian river, notwithstanding, the levels of natural and xenoestrogenic endocrine-disrupting compounds (EDCs) were never measured in its estuary. Suspecting for their presence, we made a major survey of 17 EDCs that include: (i) natural (17β-oestradiol

A simple and sensitive procedure, using p-tolylpiperazine (pTP) as internal standard (IS), has been developed and validated for the qualitative and quantitative analysis of 1-(3-trifuoromethylphenyl)piperazine (TFMPP), 1-(3-chlorophenyl)piperazine (mCPP) and 1-(4-methoxyphenyl)piperazine (MeOPP) in hair. Drug extraction was performed by incubation with

We present a false-positive result of ecstasy (3,4-methylenedioxy-NN-methylamphetamine) screening due to the therapeutic use of fenofibrate, an antihyperlipidemic drug. Our hypothesis was that the main metabolite of fenofibrate, fenofibric acid, was responsible for this cross-reactivity on a DRI(®) Ecstasy Assay

Mycobacterium leprae induces the formation of lipid droplets, which are recruited to pathogen-containing phagosomes in infected macrophages and Schwann cells. Cholesterol is among the lipids with increased abundance in M. leprae-infected cells, and intracellular survival relies on cholesterol accumulation. The

Brain preconditioning is a protective mechanism, which can be activated by sub-lethal stimulation of the NMDA receptors (NMDAR) and be used to achieve neuroprotection against stroke and neurodegenerative diseases models. Inhibitors of glycine transporters type 1 modulate glutamatergic neurotransmission through

Malondialdehyde (MDA), 4-Hydroxy-2-(E)-Nonenal (HNE) and 4-Hydroxy-2-(E)-Hexenal (HHE) are reactive aldehydes found in foods and are formed due to decomposition of polyunsaturated fatty acid hydroperoxides. In the present study, sixteen food categories were analyzed for the aforementioned aldehydes and in combination

Recently, a pyrethroid profluthrin [(2,3,5,6-tetrafluoro-4-methylphenyl)methyl 2,2-dimethyl-3-(prop-1-enyl)cyclopropane-1-carboxylate] is widely used as mothproof repellents in indoors. The urinary excretion kinetics of its metabolites was examined in rats to search for urinary metabolites suitable as biomarkers of profluthrin exposure in the general population.
