  • Using temperature-dependent changes in leaf scaling relationships to quantitatively account forthermal acclimation of respiration in a coupled global climate-vegetation model
  • 2008
  • Ingår i: Global Change Biology. ; 14, s. 2709-2726
  • Tidskriftsartikel (refereegranskat)abstract
    • <p>The response of plant respiration (R) to temperature is an important component of the biosphere's response to climate change. At present, most global models assume that R increases exponentially with temperature and does not thermally acclimate. Although we now know that acclimation does occur, quantitative incorporation of acclimation into models has been lacking. Using a dataset for 19 species grown at four temperatures (7, 14, 21, and 28 °C), we have assessed whether sustained differences in growth temperature systematically alter the slope and/or intercepts of the generalized log–log plots of leaf R vs. leaf mass per unit leaf area (LMA) and vs. leaf nitrogen (N) concentration. The extent to which variations in growth temperature account for the scatter observed in log–log R–LMA–N scaling relationships was also assessed. We show that thermal history accounts for up to 20% of the scatter in scaling relationships used to predict R, with the impact of thermal history on R–LMA–N generalized scaling relationships being highly predictable. This finding enabled us to quantitatively incorporate acclimation of R into a coupled global climate–vegetation model. We show that accounting for acclimation of R has negligible impact on predicted annual rates of global R, net primary productivity (NPP) or future atmospheric CO2 concentrations. However, our analysis suggests that accounting for acclimation is important when considering carbon fluxes among thermally contrasting biomes (e.g. accounting for acclimation decreases predicted rates of R by up to 20% in high-temperature biomes). We conclude that acclimation of R needs to be accounted for when predicting potential responses of terrestrial carbon exchange to climatic change at a regional level.</p>

  • The evolution of surface flow stripes and stratigraphic folds within Kamb Ice Stream : why don't they match?
  • 2008
  • Ingår i: Journal of Glaciology. - 0022-1430 .- 1727-5652. ; 54:186, s. 421-427
  • Tidskriftsartikel (refereegranskat)abstract
    • <p>Flow stripes seen in satellite imagery of ice streams and ice shelves are caused by surface undulations with kilometer-scale spacing and meter-scale relief and generally indicate current or recent fast ice flow. On a similar scale, folding of internal ice stratigraphy depicted in cross-flow icepenetrating radar profiles is also a common occurrence in ice streams, suggesting a possible relationship between the two sets of features. We have traced surface flow stripes in RADARSAT and MODIS imagery on Kamb Ice Stream, West Antarctica, from the onset of streaming flow into the near-stagnant trunk. We compare the morphology and evolution of the surface flow stripes to the folds seen in the internal stratigraphy in cross-ice-stream radar profiles. We find essentially no correspondence in the observed locations or spacings between the radar internal layer folds at depths greater than 100 m and the flow stripes on the surface. The gap in the radar data and the surface mappings in the top 100m of firn prevents a precise depiction of how the flow stripes and fold patterns at depth diverge. We explore hypotheses about how flow stripes and internal stratigraphic folds can originate and evolve differently as ice flows downstream. We suggest that flow stripes are subject to surface processes that can modify their morphology independently of the internal stratigraphy, leading to changes in the pattern of flow stripes relative to the internal layers below.</p>

  • Pharmacokinetics of high-dose methotrexate in infants treated for acute lymphoblastic leukemia
  • 2009
  • Ingår i: Pediatric Blood & Cancer. - 1545-5009 .- 1545-5017. ; 52:5, s. 596-601
  • Tidskriftsartikel (refereegranskat)abstract
    • <p>BACKGROUND: Interfant-99 was an international collaborative treatment protocol for infants with acute lymphoblastic leukemia (ALL). PROCEDURE: We collected data on 103 infants at the time of their first treatment with high-dose methotrexate (HD MTX), 5 g/m(2). Children &lt;6 months of age received two-third of the calculated dose based on body surface area (BSA), children 6-12 months three-fourth of the calculated dose, and children &gt;12 months full dose. RESULTS: The median steady-state MTX concentration at the end of the 24-hr infusion was 57.8 microM (range 9.5-313). The median systemic clearance was 6.22 L/hr/m(2) BSA, and tended to increase with age (P = 0.099). Boys had higher clearance than girls, 6.77 and 5.28 L/hr/m(2) (P = 0.030), and tended to have lower median MTX concentration at 24 hr. Eight infants had MTX levels below 20 microM, a level judged to be sufficient in B-lineage ALL in children &gt;1 year of age. All infants tolerated the dose well enough to receive a second dose of HD MTX without dose reduction. We found no significant effect on disease-free survival for MTX steady-state concentration, MTX clearance, or time to MTX below 0.2 microM. CONCLUSIONS: Our data provide no support for a change in the dosing rules for MTX used in Interfant-99. However, in view of the poor treatment results for infants, one might consider increase in the dose for patients who reach plasma levels below median after the first MTX dose.</p>

  • Genome sequence of Aedes aegypti, a major arbovirus vector.
  • 2007
  • Ingår i: Science (New York, N.Y.). - 1095-9203. ; 316:5832, s. 1718-23
  • Tidskriftsartikel (refereegranskat)abstract
    • <p>We present a draft sequence of the genome of Aedes aegypti, the primary vector for yellow fever and dengue fever, which at approximately 1376 million base pairs is about 5 times the size of the genome of the malaria vector Anopheles gambiae. Nearly 50% of the Ae. aegypti genome consists of transposable elements. These contribute to a factor of approximately 4 to 6 increase in average gene length and in sizes of intergenic regions relative to An. gambiae and Drosophila melanogaster. Nonetheless, chromosomal synteny is generally maintained among all three insects, although conservation of orthologous gene order is higher (by a factor of approximately 2) between the mosquito species than between either of them and the fruit fly. An increase in genes encoding odorant binding, cytochrome P450, and cuticle domains relative to An. gambiae suggests that members of these protein families underpin some of the biological differences between the two mosquito species.</p>

  • Randomized trial comparing axillary clearance versus no axillary clearance in older patients with breast cancer: first results of International Breast Cancer Study Group Trial 10-93.
  • 2006
  • Ingår i: Journal of clinical oncology : official journal of the American Society of Clinical Oncology. - 1527-7755. ; 24:3, s. 337-44
  • Tidskriftsartikel (refereegranskat)abstract
    • PURPOSE: Axillary clearance in early breast cancer aims to improve locoregional control and provide staging information but is associated with undesirable morbidity. We therefore investigated whether avoiding axillary surgery in older women would result in improved quality of life (QL) with similar disease-free survival (DFS) and overall survival (OS). PATIENTS AND METHODS: Between 1993 and 2002, women > or = 60 years old with clinically node-negative operable breast cancer in whom adjuvant tamoxifen was considered indicated regardless of pathologic nodal status were randomly assigned to primary surgery plus axillary clearance (Sx + Ax) followed by tamoxifen (Tam) versus Sx without Ax followed by Tam for 5 consecutive years. The primary end point was QL reported by the patient and by physician assessment. RESULTS: A total of 473 patients (234 to Sx + Ax, 239 to Sx) were randomly assigned. The median age was 74 years; 80% had estrogen receptor-positive disease. In both the patients' subjective assessment of their QL and the physicians' perception of the patients' QL, the largest adverse QL effects of Ax were observed from baseline to the first postoperative assessment, but the differences tended to disappear in 6 to 12 months. At a median follow-up of 6.6 years, results for Sx + Ax and Sx yielded similar DFS (6-year DFS, 67% v 66%; hazard ratio [HR] Sx + Ax/Sx, 1.06; 95% CI, 0.79 to 1.42; P = .69) and OS (6-year OS, 75% v 73%; HR Sx + Ax/Sx, 1.05; 95% CI, 0.76 to 1.46; P = .77). CONCLUSION: Avoiding axillary clearance for women > or = 60 years old who have clinically node-negative disease and receive Tam for endocrine-responsive disease yields similar efficacy with better early QL.
