We report on the mitochondrial DNA (mtDNA) analysis of the supposed remains of Francesco Petrarca exhumed in November 2003, from the S. Maria Assunta church, in Arquà Padua (Italy) where he died in 1374. The optimal preservation of the remains allowed the retrieval of sufficient mtDNA for genetic analysis. DNA was extracted from a rib and a tooth and mtDNA sequences were determined in multiple clones using the strictest criteria currently available for validation of ancient DNA sequences, including independent replication. MtDNA sequences from the tooth and rib were not identical, suggesting that they belonged to different individuals. Indeed, molecular gender determination showed that the postcranial remains belonged to a male while the skull belonged to a female. Historical records indicated that the remains were violated in 1630, possibly by thieves. These results are consistent with morphological investigations and confirm the importance of integrating molecular and morphological approaches in investigating historical remains. 相似文献

We study the impact of tenure in office on economic performance. We evaluate the relationships between tenure in office and GDP growth, public capital growth, and public capital productivity using data for Spanish regions during the period 1980?C1998. We find that tenure decreases the impact of public capital growth on GDP growth. Our results suggest that tenure affects GDP growth negatively through a decrease in public capital productivity. 相似文献

Short tandem repeats (STR)s have been the eligible markers for forensic animal genetics, despite single‐nucleotide polymorphisms (SNP)s became acceptable. The technology, the type, and amount of markers could limit the investigation in degraded forensic samples. The performance of a 32‐SNP panel genotyped through OpenArraysTM (real‐time PCR based) was evaluated to resolve cattle‐specific forensic cases. DNA from different biological sources was used, including samples from an alleged instance of cattle rustling. SNPs and STRs performance and repeatability were compared. SNP call rate was variable among sample type (average = 80.18%), while forensic samples showed the lowest value (70.94%). The repeatability obtained (98.7%) supports the used technology. SNPs had better call rates than STRs in 12 of 20 casework samples, while forensic index values were similar for both panels. In conclusion, the 32‐SNPs used are as informative as the standard bovine STR battery and hence are suitable to resolve cattle rustling investigations. 相似文献
