  • Risk factors for locoregional recurrence among breast cancer patients: results from International Breast Cancer Study Group Trials I through VII.
  • 2003
  • In: Journal of clinical oncology : official journal of the American Society of Clinical Oncology. - 0732-183X. ; 21:7, s. 1205-13
  • Journal article (peer-reviewed)abstract
    • PURPOSE: To explore prognostic factors for locoregional failures (LRF) among women treated for invasive breast cancer within clinical trials of adjuvant therapies. PATIENTS AND METHODS: The study population consisted of 5,352 women who were treated with a modified radical mastectomy and enrolled in one of seven International Breast Cancer Study Group randomized trials. A total of 1,275 women with node-negative disease received either no adjuvant therapy or a single cycle of perioperative chemotherapy, and 4,077 women with node-positive disease received adjuvant chemotherapy of at least 3 months' duration and/or tamoxifen. Median follow-up is 12 to 15.5 years. RESULTS: In women with node-negative disease, factors associated with increased risk of LRF were vascular invasion (VI) and tumor size greater than 2 cm for premenopausal and VI for postmenopausal patients. Of the 1,275 patients, 345 (27%) met criteria for the highest risk groups, and the 10-year cumulative incidences of LRF with or without distant metastases were 16% for premenopausal and 19% for postmenopausal women. For the node-positive cohort, number of nodes and tumor grade were factors for both menopausal groups, with additional prediction provided by VI for premenopausal and tumor size for postmenopausal patients. Of the 4,077 patients, 815 (20%) met criteria for the highest risk groups, and 10-year cumulative incidences were 35% for premenopausal and 34% for postmenopausal women. CONCLUSION: LRFs are a significant problem after mastectomy alone even for some patients with node-negative breast cancer, as well as after mastectomy and adjuvant treatment for some subgroups of patients with node-positive disease. In addition to number of positive lymph nodes, predictors of LRF include tumor-related factors, such as vascular invasion, higher grade, and larger size.

  • Small x phenomenology: summary and status
  • 2002
  • In: European Physical Journal C. Particles and Fields. - : Springer Science and Business Media LLC. - 1434-6044. ; 25:1, s. 77-101
  • Research review (peer-reviewed)abstract
    • The aim of this paper is to summarize the general status of our understanding of small-x physics. It is based on presentations and discussions at an informal meeting OIL this topic held in Lund, Sweden, in March 2001. This document also marks the founding of an informal collaboration between experimentalists and theoreticians with a special interest in small-x physics. This paper is dedicated to the memory of Bo Andersson. who died unexpectedly from a heart attack on March 4th, 2002.

  • Interference elimination in glutamate monitoring with chip integrated enzyme microreactors
  • 2001
  • In: Electroanalysis. - 1040-0397. ; 13:6, s. 425-431
  • Journal article (peer-reviewed)abstract
    • On-chip enzyme reactors are often used in medical/pharmaceutical analysis due to their inherent advantages, such as high sample throughput, low reagent consumption, stability, reproducibility and low cost. The present work describes a different application of such microreactors, namely, elimination of interfering ascorbate signals in glutamate monitoring using ascorbate oxidase modified silicon chip microreactors of different sizes (5.3 and 0.95 muL). Glutamate was monitored with a previously developed redox hydrogel integrated bienzyme electrode, based on coupled glutamate oxidase and horseradish peroxidase, inserted in a miniaturized flow cell operated at -50 mV (vs. Ag/AgCl). The developed on-line analysis system was characterized with regard to dilution effects, detection limit, response time and interference ability using model solutions and real samples. Off-line in vivo glutamate measurements could be made by injecting rat brain microdialysate samples collected before and after KCl stimulation without any interference of ascorbate, I Within the studied flow rate range (2-25 muL/min), 1 mM and 200 muM ascorbate could he totally eliminated using the larger and the mailer microreactor, respectively.

  • An unusual Streptococcus from human urine, Streptococcus urinalis sp. nov.
  • 2000
  • In: International journal of systematic and evolutionary microbiology. - 1466-5026. ; 50 Pt 3, s. 1173-8
  • Journal article (peer-reviewed)abstract
    • Biochemical, molecular chemical and molecular genetic studies were performed on an unknown Gram-positive, catalase-negative, chain-forming coccus isolated from the urine of a patient suffering from cystitis. Comparative 16S rRNA gene sequencing showed that the organism is a member of the 'pyogenic subgroup' of the genus Streptococcus and has a close affinity with Streptococcus pyogenes and Streptococcus canis. The unknown coccus was, however, readily distinguished from these species and other streptococci by biochemical tests and electrophoretic analysis of whole-cell proteins. Based on phenotypic and phylogenetic evidence, it is proposed that the unknown bacterium be classified as a new species of the genus Streptococcus, Streptococcus urinalis sp. nov. The type strain of Streptococcus urinalis is CCUG 41590T.

  • Arsenicicoccus bolidensis gen. nov., sp nov., a novel actinomycete isolated from contaminated lake sediment
  • 2004
  • In: INTERNATIONAL JOURNAL OF SYSTEMATIC AND EVOLUTIONARY MICROBIOLOGY. - : Microbiology Society. - 1466-5026 .- 1466-5034. ; 54, s. 605-608
  • Journal article (peer-reviewed)abstract
    • An unknown Gram-positive, catalase-positive, facultatively anaerobic, non-spore-forming, coccus-shaped bacterium originating from sediment was characterized using phenotypic, molecular chemical and molecular phylogenetic methods. Chemical studies revealed the presence of a cell-wall murein based on ll-diaminopimelic acid (type ll-Dpm-glycine1), a complex mixture of saturated, monounsaturated and iso- and anteiso-methyl-branched, non-hydroxylated, long-chain cellular fatty acids and tetrahydrogenated menaquinones with eight isoprene units [MK-8(H4)] as the major respiratory lipoquinone. This combination of characteristics somewhat resembled members of the suborder Micrococcineae, but did not correspond to any currently described species. Comparative 16S rRNA gene sequencing confirmed that the unidentified coccus-shaped organism is a member of the Actinobacteria and represents a hitherto-unknown subline related to, albeit different from, a number of taxa including Intrasporangium, Janibacter, Terrabacter, Terracoccus and Ornithinicoccus. Based on phenotypic and phylogenetic considerations, it is proposed that the unknown bacterium originating from lake sediment be classified as a new genus and species, Arsenicicoccus bolidensis gen. nov., sp. nov. (type strain CCUG 47306T=DSM 15745T).
