- We present here a draft genome sequence of the red jungle fowl, Gallus gallus. Because the chicken is a modern descendant of the dinosaurs and the first non-mammalian amniote to have its genome sequenced, the draft sequence of its genome--composed of approximately one billion base pairs of sequence and an estimated 20,000-23,000 genes--provides a new perspective on vertebrate genome evolution, while also improving the annotation of mammalian genomes. For example, the evolutionary distance between chicken and human provides high specificity in detecting functional elements, both non-coding and coding. Notably, many conserved non-coding sequences are far from genes and cannot be assigned to defined functional classes. In coding regions the evolutionary dynamics of protein domains and orthologous groups illustrate processes that distinguish the lineages leading to birds and mammals. The distinctive properties of avian microchromosomes, together with the inferred patterns of conserved synteny, provide additional insights into vertebrate chromosome architecture.

- The objective of this study was to compare the safety and efficacy of carboplatin plus epirubicin and paclitaxel (TEC) to carboplatin and paclitaxel (TC), in the treatment of epithelial ovarian, peritoneal, or tubal carcinoma. Between March 1999 and August 2001, 887 patients were randomized to receive six to nine cycles of paclitaxel (175 mg/m2, 3 h intravenously) followed by carboplatin (AUC 5, Calvert formula) with or without epirubicin (75 mg/m2 intravenously prior to paclitaxel), on a 3-weekly schedule. The primary endpoint was progression-free survival. Demographic information: Residual disease <1 cm was reported on 41% of patients. At the end of treatment, 65% in the TEC and 55% in the TC arm had achieved a clinical complete response, and 18 and 25% a clinical partial response resulting in an overall response rate of 83% in the TEC and 80% in the TC arm, whereas 7 and 9% had progressive disease, respectively. The three-drug combination produced a markedly higher myelotoxicity, resulting in a higher frequency of febrile neutropenia (12.5% of the TEC and 1.5% of the TC patients) and a higher number of dose reductions and treatment delays. Cycle prolongation above seven days was seen in 7 and 5% of cycles in the TEC and TC arm, respectively. Stomatitis > or = grade 3 was also higher with TEC (4% TEC and 0.5% TC). Reductions in left ventricular ejection fraction of more than 15% after six courses were slightly more common with the TEC regimen (3% versus 1.5%), but the difference was not statistically significant (P = 0.2). In conclusion, treatment with the TEC combination produced a higher rate of complete responses than treatment with the TC combination. Toxicity was manageable. Long-term survival data are awaited.

Radio-wave inferometry for BOS slag control
- 2001
-
Rapport (refereegranskat)abstract
- The aim of the project is to use radio-wave interferometry to determine the BOF slag and metal heights in both a quiescent and a blowing BOS convertor. The hydrodynamics of the slag/metal emulsion and 1, 2 and possibly 3D representations of slag and metal movements during the blowing phase will be made. Process factors such as vessel shape, lance movements, bath agitation, flux/ore additions and fume generation will be considered.
