"Herodotus the Tourist" was the title given by James Redfield to his inquiry into Herodotus's ethnological system (Classical Philology, 80.2, 1985: 97-118). Redfield's insights, together with François Hartog's monograph The mirror of Herodotus (University of California Press, 1988), definitively modified our interpretation of Herodotus's Histories. In the present paper, I analyse the so-called Letter of Aristeas from a narratological perspective, suggesting that the anonymous author of the Letter deliberately constructed his main character ("Aristeas") as a Herodotus-like figure, who visits Judea and Jerusalem as yet another "tourist". In so-doing, the author's pseudo-ethnographic text produces a specific Jewish self-definition and identity in the Hellenistic period, mirroring both Greek representations of the Jews as a people of philosophers, and a Jewish interpretation of the ideal bios philosophikos, best typified through the Jewish compliance with the Mosaic legislation.

Modern imaging technologies, such as computed tomography (CT) techniques, represent a great challenge in forensic pathology. The field of forensics has experienced a rapid increase in the use of these new techniques to support investigations on critical cases, as indicated by the implementation of CT scanning by different forensic institutions worldwide. Advances in CT imaging techniques over the past few decades have finally led some authors to propose that virtual autopsy, a radiological method applied to post-mortem analysis, is a reliable alternative to traditional autopsy, at least in certain cases. The authors investigate the occurrence and the causes of errors and mistakes in diagnostic imaging applied to virtual autopsy. A case of suicide by a gunshot wound was submitted to full-body CT scanning before autopsy. We compared the first examination of sectional images with the autopsy findings and found a preliminary misdiagnosis in detecting a peritoneal lesion by gunshot wound that was due to radiologist's error. Then we discuss a new emerging issue related to the risk of diagnostic failure in virtual autopsy due to radiologist's error that is similar to what occurs in clinical radiology practice.

Monosomy 1p36 results from heterozygous deletions of the terminal short chromosome 1 arm, the most common terminal deletion in humans. The microdeletion is split in two usually non-overlapping and clinically distinct classical distal and proximal 1p36 monosomy syndromes. Using comparative genome hybridization, MLPA and qPCR we identified the largest contiguous ∼16 Mb terminal 1p36 deletion reported to date. It covers both distal and proximal regions, causes a neonatally lethal variant with virtually exclusive features of distal 1p36 monosomy, highlighting the key importance of the gene-rich distal region for the "compound" 1p36 phenotype and a threshold deletion-size effect for haplo-lethality.

Considerable efforts have been directed toward the identification of small-ruminant prion diseases, i.e., classical and atypical scrapie as well as bovine spongiform encephalopathy (BSE). Here we report the in-depth molecular analysis of the proteinase K-resistant prion protein core fragment (PrP(res)) in a highly scrapie-affected goat flock in Greece. The PrP(res) profile by Western immunoblotting in most animals was that of classical scrapie in sheep. However, in a series of clinically healthy goats we identified a unique C- and N-terminally truncated PrP(res) fragment, which is akin but not identical to that observed for atypical scrapie. These findings reveal novel aspects of the nature and diversity of the molecular PrP(res) phenotypes in goats and suggest that these animals display a previously unrecognized prion protein disorder.

The association between PRNP variation and scrapie incidence was investigated in a highly affected Greek goat herd. Four mutations were identified at codons 171Q/R, 211R/Q, 222Q/K and 240P/S. Lysine at codon 222 was found to be associated with the protection from natural scrapie (P=0.0111). Glutamine at codon 211 was observed in eight animals, all of them being scrapie-negative, indicating a possible protective role of this polymorphism although statistical analysis failed to support it (P=0.1074). A positive association (P=0.0457) between scrapie-affected goats and the wild-type Q(171)R(211)Q(222)S(240) allele is presented for the first time. In addition, a novel R(171)RQS allele, which is identical to the A(136)R(154)R(171) allele that has been associated with resistance to classical scrapie in sheep, was observed in low frequency. Resistant alleles that include K(222) and Q(211) are absent or rare in sheep and can provide the basis for the development of a feasible breeding programme for scrapie eradication in goats.
