Ochratoxin A in the morning and afternoon portions of urine from Coimbra and Valencian populations.

2008

Abstract The widespread contamination of foodstuffs and beverages by mycotoxins, such as ochratoxin A (OTA), has made the monitoring of human contamination levels essential. By using a sensitive, accurate and speedy method that combines extraction with 5% NaHCO 3 , immunoaffinity column clean-up and HPLC with fluorescence detection, the human exposure to OTA through urine analysis can be monitored. This method is less invasive than blood monitoring and has the potential to be a good marker of human exposure. The limit of quantification of the method was 0.007 ng/mL of urine, with recoveries of OTA, from urine samples spiked at levels between 0.02 and 0.1 ng/mL, higher than 91% with RSD lowe…

This paper describes the study of human fibrocartilaginous entheses in a multiple indigenous sicanian Sicilian burial dated between VI and V century BC. The tomb, a cave burial, was altered by grave robbers. From the collected osteologic material it was possible to perform the sorting method and to extrapolate the NMI. The research was focused on the scoring and on the analysis of the Entheseal Changes (EC) of the long bones of upper limb and calcaneus; to extrapolate likely patterns of muscle activity according to the approach of the MSM applied in literature we have utilized the Coimbra Method. This method is a new record method who intends to replace Hawkey and Merbs already-established …

Early Jurassic (Sinemurian) gastropods from the Lusitanian Basin (west of Portugal)

2020

The Sinemurian gastropod specimens herein studied come from two sources: from museum collections and from samplings in field. The study of the Sinemurian gastropod specimens housed in the collections of the Museu Geológico (Laboratório Nacional de Energia e Geologia), Museu Nacional de História Natural e da Ciência (University of Lisbon), Museu da Ciência (University of Coimbra) and of the Museu de História Natural e da Ciência (University of Porto), has allowed the systematic and taxonomical update of this material. These specimens come mostly from Sinemurian outcrops in S. Pedro de Moel area and Coimbra region, and were collected by Paul Choffat and collaborators in the geological field w…
