Variants : The Journal of the European Society for Textual Scholarship

This volume is the 10th issue of Variants . In keeping with the mission of the European Society for Textual Scholarship, the articles are richly interdisciplinary and transnational. They bring to bear a wide range of topics and disciplines on the field of textual scholarship: historical linguistics, digital scholarly editing, classical philology, Dutch, English, Finnish and Swedish Literature, publishing traditions in Japan, book history, cultural history and folklore. The questions that are explored - what texts are worth editing? what is the nature of the relationship between text, work, document and book? what is a critical digital edition? - all return to fundamental issues that have been at the heart of the editorial discipline for decades. With refreshing insight they assess the increasingly hybrid nature of the theoretical considerations and practical methodologies employed by textual scholars, while reasserting the relevance and need for producing scholarly editions, whether in print or digital, and continuing advanced research in bibliographical codes, textual transmissions, genetic dossiers, the fluidity of texts and other such subjects that connect textual scholarship with broader investigations into our nations' literary culture and written heritage.

La legislació constantiniana respecte de l'episcopalis audientia.

Dues disposicions de Constantí -el Codex Theodosiallus I, 27, 1 (318) i la COllstitutio Sirmondina I (333)- constitueixen la primera san ció legal del poder jurídic deIs bisbes en afers externs a la religió. Al voltant d' elles creix una nova institució eclesiastica, l' episcopalis audientia, la qual, recollint els preceptes cristians tradicionals, aplica el dret imperial en la resolució de causes de naturales a civil. La controvertida veracitat de les lIeis constantinianes i la varietat d' interpretacions que susciten depassen l' ambit d' allo estrictament jurídic per endinsar-se en la canviant societat romana del segle IV.

The influence of bacterial activity on phosphorite formation in the Miocene Monterey Formation, California

Authigenic phosphorites from the Miocene Monterey Formation (California) including an autochthonous phosphatic laminite were analyzed for molecular biomarkers, element content, and sulfur isotopic composition of associated pyrite and sulfate to evaluate the role of bacterial activity in the precipitation of phosphate minerals. The phosphorites formed in a depositional environment typified by upwelling with dynamic bottom currents and hardground formation. Pyrite enclosed in the phosphorites shows delta S-34 values as low as -36.5 parts per thousand VCDT, which is consistent with bacterial sulfate reduction. In a three-step extraction phosphorite dissolution extraction procedure, molecular fossils of sulfate-reducing bacteria (di-O-alkyl glycerol ethers and short-chain branched fatty acids i- and ai-C-15:0, i- and ai-C-17:0, and 10MeC(16:0)) were preferentially released from the mineral lattice. This suggests that the molecular fossils were tightly bound to carbonate fluorapatite, indicating that sulfate-reducing bacteria were involved in mineral formation. A close association of sulfate-reducing bacteria with large sulfide-oxidizing bacteria, which was previously suggested to favor carbonate fluorapatite precipitation, could neither be confirmed nor excluded for the Miocene Monterey Formation phosphorites.

The frequency and prognostic impact of dic(9;20)(p13.2;q11.2) in childhood B-cell precursor acute lymphoblastic leukemia: results from the NOPHO ALL-2000 trial.

The dic(9;20)(p13.2;q11.2) is reported to be present in ∼2% of childhood B-cell precursor acute lymphoblastic leukemia (BCP ALL). However, it easily escapes detection by G-banding analysis and its true prevalence is hence unknown. We performed interphase fluorescence in situ hybridization analyses-in a three-step manner-using probes for: (i) CDKN2A at 9p21, (ii) 20p and 20q subtelomeres and (iii) cen9 and cen20. Out of 1033 BCP ALLs diagnosed from 2001 to 2006, 533 were analyzed; 16% (84/533) displayed 9p21 deletions, of which 30% (25/84) had dic(9;20). Thus, dic(9;20)-positivity was found in 4.7% (25/533), making it the third most common genetic subgroup after high hyperdiploidy and t(12;21)(p13;q22). The dic(9;20) was associated with a female predominance and an age peak at 3 years; 18/25 (72%) were allocated to non-standard risk treatment at diagnosis. Including cases detected by G-banding alone, 29 dic(9;20)-positive cases were treated according to the NOPHO ALL 2000 protocol. Relapses occurred in 24% (7/29) resulting in a 5-year event-free survival of 0.69, which was significantly worse than for t(12;21) (0.87; P=0.002) and high hyperdiploidy (0.82; P=0.04). We conclude that dic(9;20) is twice as common as previously surmised, with many cases going undetected by G-banding analysis, and that dic(9;20) should be considered a non-standard risk abnormality.

Experimental cutaneous Leishmaniasis: a powerful model to study in vivo the mechanisms underlying genetic differences in Th subset differentiation.

The murine model of infection with Leishmania major has allowed the demonstration in vivo of the importance CD4+ T cell subsets, distinguishable by the pattern of cytokines they produce, on the outcome of infectious diseases. Genetically determined resistance and susceptibility to infection with this parasite are the result of the development of Th1 and Th2 response, respectively. In this short paper, we present some results obtained in our group pertaining to the analysis of the mechanisms, operational during the early phase of this infection, responsible for the maturation of these functionally distinct CD4+ responses.

Aarskog-Scott syndrome: clinical update and report of nine novel mutations of the FGD1 gene.

Mutations in the FGD1 gene have been shown to cause Aarskog-Scott syndrome (AAS), or facio-digito-genital dysplasia (OMIM#305400), an X-linked disorder characterized by distinctive genital and skeletal developmental abnormalities with a broad spectrum of clinical phenotypes. To date, 20 distinct mutations have been reported, but little phenotypic data are available on patients with molecularly confirmed AAS. In the present study, we report on our experience of screening for mutations in the FGD1 gene in a cohort of 60 European patients with a clinically suspected diagnosis of AAS. We identified nine novel mutations in 11 patients (detection rate of 18.33%), including three missense mutations (p.R402Q; p.S558W; p.K748E), four truncating mutations (p.Y530X; p.R656X; c.806delC; c.1620delC), one in-frame deletion (c.2020_2022delGAG) and the first reported splice site mutation (c.1935+3A>C). A recurrent mutation (p.R656X) was detected in three independent families. We did not find any evidence for phenotype-genotype correlations between type and position of mutations and clinical features. In addition to the well-established phenotypic features of AAS, other clinical features are also reported and discussed.

Pathogenesis of streptococcal and staphylococcal endocarditis.

Although streptococcal and S. aureus IE share the same primary site of infection, their pathogenesis and clinical evolution present several major differences. Streptococci adhere to cardiac valves with pre-existing endothelial lesions. In contrast, S. aureus can colonize either damaged endothelium or invade physically intact endothelial cells. These interactions are mediated by multiple surface adhesins, some of which have been only partially characterized. Streptococci produce surface glucans (gtf and ftf), ECM adhesins (e.g., fibronectin-binding proteins, FimA), and platelet aggregating factors (phase I and phase II antigens, pblA, pblB, and pblT), all of which have been.
