Risk assessment associated to the intake of the emerging Fusarium mycotoxins BEA, ENs and FUS present in infant formula of Spanish origin
2012
Abstract Forty-five samples of Spanish follow-up infant formula with different chemical compositions were analyzed determining the emerging Fusarium mycotoxins beauvericin (BEA), enniatins (ENs) (A, A 1 , B, B 1 ), and fusaproliferin (FUS). The samples were extracted three times with ethyl acetate using an Ultra-turrax homogenizer. Mycotoxins were identified and quantified using a liquid chromatography (LC) coupled to a diode array detector (DAD). Results showed that the percentage of the samples contaminated with ENs and FUS were 46.6 and 20.0% respectively, whereas all analyzed samples were free of BEA. The ENs A and B were detected only in one sample with 149.6 and 39.4 mg/kg respectivel…
Sex-Specific Genetic Effects Associated with Pigmentation, Sensitivity to Sunlight, And Melanoma in a Population of Spanish Origin
2016
Background Human pigmentation is a polygenic quantitative trait with high heritability. In addition to genetic factors, it has been shown that pigmentation can be modulated by oestrogens and androgens via up- or down-regulation of melanin synthesis. Our aim was to identify possible sex differences in pigmentation phenotype as well as in melanoma association in a melanoma case-control population of Spanish origin. Methods Five hundred and ninety-nine females (316 melanoma cases and 283 controls) and 458 males (234 melanoma cases and 224 controls) were analysed. We genotyped 363 polymorphisms (single nucleotide polymorphisms (SNPs)) from 65 pigmentation gene regions. Results When samples were…
