BACKGROUND Valproate is used widely for the treatment of epilepsy but has been associated with hyperandrogenism, hyperinsulinemia, and dyslipidemia. The mechanism for these associations is unknown, but they have been hypothesized to be secondary to valproate-associated weight gain. This study was conducted to test the hypothesis that the antiepileptic drug… (More)
Concentrations of PCBs, PCDDs, and PCDFs, heavy metals (Cu, Cd, Zn, Pb, and Hg), and arsenic have been determined in a great variety of food samples purchased in different markets across the city of Huelva, located in southwestern Spain and under strong industrial activity. All samples analyzed presented concentrations below the maximum allowed by the… (More)
Organochlorine compounds (OCs) including polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs), polychlorinated biphenyls (PCBs) and 1,1-dichloro-2,2-bis(p-chlorophenyl)ethylene (p-p'-DDE), heavy metals (Pb, Cd, Zn, Cu), and arsenic were measured in house sparrows (Passer domesticus) and common ground doves (Columbina passerina) from Baja… (More)
In this study samples of common trout, European eel and barbel have been analysed for the levels of heavy metals such as lead (Pb), cadmium (Cd), zinc (Zn), copper (Cu), and the metalloid arsenic (As). Polychlorinated biphenyls (PCBs), including three non-ortho substituted PCBs, 2,3,7,8-substituted polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated… (More)
Ordered mesoporous carbons have been applied, for the first time, as catalysts for hydrogen production via methane decomposition, showing higher and more stable activity than commercial carbonaceous catalysts.
This article presents the impact on waterbirds in Doñana National Park (Spain) of an accidental release of 5 million m3 acid waste produced by the processing of pyrite ore. Heavy metals (zinc, copper, cadmium, and lead) and arsenic were measured in several soft tissues (liver, kidney, and muscle) taken from 14 waterfowl species collected between April 1998… (More)
We have monitored the distribution, population status, breeding success, turnover rate and diet of a Peregrine Falcon population in Bizkaia (North of Spain) since 1997. On the 13th November 2002, the tanker Prestige sunk off La Coruña (NW Spain) causing an oil spill that affected the whole of the Cantabrian Coast and the Southwest of France. The total… (More)
This work presents the concentrations of twenty PCB congeners, p,p'-DDT, and its two main metabolites, p,p'-DDE, p,p'-TDE, As, Cd, Cu, Pb, and Zn found in common chameleon eggs from nine different nests located in Southwest Spain. Of the heavy metals and arsenic, Zn and Cu exhibited the highest concentrations in egg contents (ranging from 10100 to 12950 and… (More)
Exposure to heavy metals from emissions of the solid-waste incinerator (SWI) of Madrid (Spain) was assessed by determining the relationships between the distance from black kite (Milvus migrans) nests to the SWI and metal concentrations in nestling blood and failed eggs. Lead levels increased as the distance to the SWI decreased, while no significant… (More)
We performed a crystallographic study of two cases of milk of calcium lithiasis. Dust from the specimens were studied by x-ray diffraction and thin layer light microscopy. Analyses of the different morphological types and their layers revealed these to be comprised of wewellite and calcium phosphate, except one with pure wewellite in its core and cortex.
