L'organisation des manuscrits arthuriens du cycle du Graal de Jacques d'Armagnac (BNF fr. 117-120 qu'il a hérité de son arrière-grand-père le duc Jean de Berry et dont il a fait retoucher les peintures et BNF fr. 113-116 qu'il a fait exécuter entre 1470 et 1475), leur agencement, leur illustration et leurs subdivisions sont un indice précieux de la conception et de la réception de ces compilations. Ils soulignent l'effort de constitution d'un ensemble romanesque cohérent centré sur la figure de Lancelot.

Genetic associations between accumulated productivity, and reproductive and growth traits in Nelore cattle

The total meat yield in a beef cattle production cycle is economically very important and depends on the number of calves born per year or birth season, being directly related to reproductive potential. Accumulated Productivity (ACP) is an index that expresses a cow's capacity to give birth regularly at a young age and to wean animals of greater body weight. Using data from cattle participating in the "Program for Genetic Improvement of the Nelore Breed" (PMGRN - Nelore Brasil), bi-trait analyses were performed using the Restricted Maximum Likelihood method based on an ACP animal model and the following traits: age at first calving (AFC), female body weight adjusted for 365 (BW365) and 450 (BW450) days of age, and male scrotal circumference adjusted for 365 (SC365), 450 (SC450), 550 (SC550) and 730 (SC730) days of age. Median estimated ACP heritability was 0.19 and the genetic correlations with AFC, BW365, BW450, SC365, SC450, SC550 and SC730 were 0.33, 0.70, 0.65, 0.08, 0.07, 0.12 and 0.16, respectively. ACP increased and AFC decreased over time, revealing that the selection criteria genetically improved these traits. Selection based on ACP appears to favor the heaviest females at 365 and 450 days of age who showed better reproductive performance as regards AFC. Scrotal circumference was not genetically associated with ACP. (C) 2007 Elsevier B.V. All rights reserved.

Messung von Q beta-Werten neutronenreicher Tc- bis Pd-Isotope im Massenbereich A=110 bis A=117

In der vorliegenden Arbeit wurden zwölf Q(beta)-Werte von beta-instabilen Pd, Ru, Rh und Tc-Isotopen gemessen. Der betrachtete Massenbereich A=110 bis A=117 liegt am Rande des bekannten Gebiets der Nuklidkarte und umfasst sehr neutronenreiche kurzlebige Isotope dieser Elemente, die sich durch geringe Spalthäufigkeit auszeichnen. Durch die geringen (Spalt-)Häufigkeiten dieser Nuklide liegen kaum Daten vor, teilweise auch nicht über die Niveauschemata. Es ist daher notwendig, eine protoneninduzierte Spaltungsreaktion zur Darstellung dieser Isotope zu verwenden und die Spaltprodukte innerhalb kürzester Zeit für die Messung nach Massen aufzutrennen, wie dies am IGISOL in Jyväskylä/Finnland geschieht. Die aufgebaute Apparatur zur beta,gamma,X-Koinzidenz erlaubt es, während ein und desselben Experiments neben der Messung der Q(beta)-Werte gleichzeitig gamma,X-Koinzidenzen auszuwerten, die die benötigten Grundinformationen für die Q(beta)-Bestimmung über die beta,gamma-Koinzidenzen liefern. Es können somit nicht nur Q(beta)-Werte von Nukliden mit bereits bekannten Niveauschemata ermittelt, sondern auch erfolgreich Nuklide mit unvollständigen Niveauschemata einer ersten Messung unterzogen werden. Umgekehrt können beta,gamma-Koinzidenzdaten weitere Informationen zum Aufbau neuer Niveauschemata liefern. Mit Hilfe der beschriebenen Koinzidenzmessung konnten zwölf Q(beta)-Werte von sehr neutronenreichen Pd- bis Tc-Isotopen gemessen und daraus die Kernmassen, Massenüberschüsse und Neutronen-Separationsenergien bestimmt werden. Von diesen wurden acht Werte erstmalig bestimmt, ein weiterer Wert konnte bestätigt sowie die Fehler von drei weiteren Werten um den Faktor Zehn verringert werden. Die gewonnenen Daten sind von Interesse für die Beurteilung von Kernmassenmodellen und gehen ebenso in Modellrechnungen der nuklearen Astrophysik ein.

[Precancerous and high risk lesions of the oral mucosa--Diagnosis, therapy and follow-up in two cases]

Stomatologic lesions at risk to develop an oral squamous cell carcinoma (OSCC) such as oral leukoplakia, erythroplakia/erythroleukoplakia, or oral lichen planus, need an early detection, diagnosis and a long-term/lifelong follow-up to prevent malignant transformation. In the following report, two patients are presented with oral mucosal lesions, who were referred, diagnosed, treated, and underwent follow-up examinations at the Stomatology Service of the Department of Oral Surgery and Stomatology at the University of Bern. These two cases emphasize the importance of early detection and managment of precancerous lesions or initial stages of OSCC. Additionally, risk factors, such as tobacco and alcohol consumption and their influence on stomatologic lesions and their prognosis, will be discussed.

Detection of cryptic pathogenic copy number variations and constitutional loss of heterozygosity using high resolution SNP microarray analysis in 117 patients referred for cytogenetic analysis and impact on clinical practice

BACKGROUND: Microarray genome analysis is realising its promise for improving detection of genetic abnormalities in individuals with mental retardation and congenital abnormality. Copy number variations (CNVs) are now readily detectable using a variety of platforms and a major challenge is the distinction of pathogenic from ubiquitous, benign polymorphic CNVs. The aim of this study was to investigate replacement of time consuming, locus specific testing for specific microdeletion and microduplication syndromes with microarray analysis, which theoretically should detect all known syndromes with CNV aetiologies as well as new ones. METHODS: Genome wide copy number analysis was performed on 117 patients using Affymetrix 250K microarrays. RESULTS: 434 CNVs (195 losses and 239 gains) were found, including 18 pathogenic CNVs and 9 identified as "potentially pathogenic". Almost all pathogenic CNVs were larger than 500 kb, significantly larger than the median size of all CNVs detected. Segmental regions of loss of heterozygosity larger than 5 Mb were found in 5 patients. CONCLUSIONS: Genome microarray analysis has improved diagnostic success in this group of patients. Several examples of recently discovered "new syndromes" were found suggesting they are more common than previously suspected and collectively are likely to be a major cause of mental retardation. The findings have several implications for clinical practice. The study revealed the potential to make genetic diagnoses that were not evident in the clinical presentation, with implications for pretest counselling and the consent process. The importance of contributing novel CNVs to high quality databases for genotype-phenotype analysis and review of guidelines for selection of individuals for microarray analysis is emphasised.
