  • Polarisation of the omega meson in the pd -> He-3 omega reaction at 1360 and 1450 MeV
  • 2008
  • Ingår i: Physics Letters B. - elsevier : Elsevier BV. - 0370-2693 .- 1873-2445. ; 668:4, s. 258-262
  • Tidskriftsartikel (refereegranskat)abstract
    • The tensor polarisation of omega mesons produced in the pd -> He-3 omega reaction has been studied at two energies near threshold. The 3 He nuclei were detected in coincidence with the pi(0)pi(+)pi(-) or pi(0)gamma decay products of the omega. in contrast to the case of phi-meson production, the omega mesons are found to be unpolarised. This brings into question the applicability of the Okubo-Zweig-lizuka rule when comparing the production of vector mesons in low energy hadronic reactions.

  • Production of the omega meson in the pd -> He-3 omega reaction at 1450 MeV and 1360 MeV
  • 2009
  • Ingår i: Physical Review C. Nuclear Physics. - 0556-2813 .- 1089-490X. ; 79:4, s. 044002-
  • Tidskriftsartikel (refereegranskat)abstract
    • The production of omega mesons in the pd -> He-3 omega reaction has been studied at two energies near the kinematic threshold, T-p = 1450 MeV and T-p = 1360 MeV. The differential cross section was measured as a function of the omega c.m. angle at both energies over the whole angular range. Whereas the results at 1360 MeV are consistent with isotropy, strong rises are observed near both the forward and backward directions at 1450 MeV. Calculations made using a two-step model with an intermediate pion fail to reproduce the shapes of the measured angular distributions and also underestimate the total cross sections.

  • Double-Pionic Fusion of Nuclear Systems and the "ABC" Effect : Approaching a Puzzle by Exclusive and Kinematically Complete Measurements
  • 2009
  • Ingår i: Physical Review Letters. - 0031-9007 .- 1079-7114. ; 102:5, s. 052301-
  • Tidskriftsartikel (refereegranskat)abstract
    • The ABC effect-a puzzling low-mass enhancement in the pi pi invariant mass spectrum, first observed by Abashian, Booth, and Crowe-is well known from inclusive measurements of two-pion production in nuclear fusion reactions. Here we report on the first exclusive and kinematically complete measurements of the most basic double-pionic fusion reaction pn -> d pi(0)pi(0) at beam energies of 1.03 and 1.35 GeV. The measurements, which have been carried out at CELSIUS-WASA, reveal the ABC effect to be a (pi pi)(I=L=0) channel phenomenon associated with both a resonancelike energy dependence in the integral cross section and the formation of a Delta Delta system in the intermediate state. A corresponding simple s-channel resonance ansatz provides a surprisingly good description of the data.

  • Measurement of eta meson decays into lepton-antilepton pairs
  • 2008
  • Ingår i: Physical Review D. Particles and fields. - : American Physical Society. - 0556-2821 .- 1089-4918. ; 77:3, s. 032004-
  • Tidskriftsartikel (refereegranskat)abstract
    • A search for rare lepton decays of the eta meson was performed using the WASA detector at CELSIUS. Two candidates for double Dalitz decay eta -> e(+)e(-)e(+)e(-) events are reported with a background of 1.3 +/- 0.2 events. This allows to set an upper limit to the branching ratio of 9.7x10(-5) (90% CL). The branching ratio for the decay eta -> e(+)e(-)gamma is determined to (7.8 +/- 0.5(stat)+/- 0.8(syst))x10(-3) in agreement with world average value. An upper limit (90% CL) for the branching ratio for the eta -> e(+)e(-) decay is 2.7x10(-5) and a limit for the sum of the eta ->mu(+)mu(-)mu(+)mu(-) and eta ->pi(+)pi(-)mu(+)mu(-) decays is 3.6x10(-4).

    • En central fråga i förstudien om fenomenet Ullared är att identifiera motiven till att människor reser till Gekås Ullared för att handla. Lokaliseringen på landsbygden i Halland skiljer sig avsevärt från andra etablerade varuhus i Sverige och internationellt. Gekås omsätter 2009 över tre miljarder kronor. Statistik från Gekås visar att en genomsnittlig besökare under 2008 hade rest 23 mil enkel resa och besöker Gekås två gånger per år. Flera av de vi träffade under vårt fältarbete i augusti 2009 var långväga gäster. Ett exempel är familjen som stod först i kön på lördagsmorgonen och väntade på att varuhuset skulle öppna klockan 07:00. De hade rest femtio mil under natten för att komma fram i tid. Även den familj som stod sist i kön hade rest femtio mil. Vad motiverar människor att resa så långt för att handla på Gekås? Mina reflektioner från förstudien är kopplade till denna frågeställning och till familjekonsumtion. Under de tre dagar vi tillbringade på campingen och på Gekås i Ullared observerade jag och gjorde intervjuer med familjer och personal. Intervjuerna med familjerna var kortare och tidsmässigt spontana i jämförelse med intervjuerna med personal som planerades in under vårt besök på varuhuset. Studiens begränsade karaktär gör det inte möjligt att generalisera utifrån resultaten, något som heller aldrig varit avsikten med denna förstudie. I stället har den möjliggjort en viss inblick i familjekonsumtion och en mer övergripande reflektion om konsumtion relaterat till konformitet och distinktion. I kapitlet diskuteras först familjekonsumtion och sedan konformitet och distinktion.

    • Ullared har de flesta hört talas om, i synnerhet efter höstens dokusåpa som fått stor uppmärksamhet i media. Ullared är en liten ort med flera företag, men det dominerande företaget är varuhuset Gekås Ullared. Under 2008 besökte närmare fyra miljoner personer Gekås. Gekås omsatte 2009 över tre miljarder kronor. Gekås säljer bl.a. hundra miljoner bullformar, tolv miljoner bakplåtspapper, en miljon flaskor schampo, tolv miljoner sockor och 2 000 ton godis per år. I Ullared möts handel och konsumtion.

    • Motivation: Extracellular vesicles (EVs) are spherical bilayered proteolipids, harboring various bioactive molecules. Due to the complexity of the vesicular nomenclatures and components, online searches for EV-related publications and vesicular components are currently challenging. Results: We present an improved version of EVpedia, a public database for EVs research. This community web portal contains a database of publications and vesicular components, identification of orthologous vesicular components, bioinformatic tools and a personalized function. EVpedia includes 6879 publications, 172 080 vesicular components from 263 high-throughput datasets, and has been accessed more than 65 000 times from more than 750 cities. In addition, about 350 members from 73 international research groups have participated in developing EVpedia. This free web-based database might serve as a useful resource to stimulate the emerging field of EV research.

  • THE pp -> d pi(+)pi(0) REACTION - A CASE OF Delta Delta EXCITATION WITHOUT ABC-EFFECT
  • 2009
  • Ingår i: International Journal of Modern Physics A. - 0217-751X .- 1793-656X. ; 24:2-3, s. 561-563
  • Tidskriftsartikel (refereegranskat)abstract
    • The ABC effect, a low-mass enhancement in the invariant pp mass, is observed in double-pionic fusion reactions leading to a bound nuclear system in the final state. From previous measurements there have been indications that this phenomenon is resctricted to the sigma channel of the pp system. With exclusive measurements of the pp -> d pi(+)pi(0) reaction at T-p = 1.1 GeV we demonstrate that, indeed, the ABC effect does not occur in the vector-isovector Delta Delta channel (rho channel) despite the fact that the Delta Delta excitation is oberved to be the dominant reaction process. We also show that this reaction is well described by a t-channel Delta Delta excitation with the subsequent decay into the vector-isovector Delta Delta channel given by the rho channel operator.

  • 2010
  • Ingår i: European Physical Journal A. - : Springer Science and Business Media LLC. - 1434-6001 .- 1434-601X. ; 45:1, s. 11-21
  • Tidskriftsartikel (refereegranskat)abstract
    • The cross-sections of the pd -> He-3 eta, pd -> He-3 pi(0)pi(0)pi(0) and pd -> He-3 pi(+)pi(-)pi(0) reactions have been measured at the beam kinetic energies T-p = 1360 MeV and T-p = 1450 MeV using the CELSIUS/WASA detector setup. At both energies, the differential cross-section d sigma/d Omega of the eta meson in the pd -> He-3 eta reaction shows a strong forward-backward asymmetry in the CMS. The ratio between the pd -> He-3 pi(+)pi(-)pi(0) and pd -> He-3 pi(0)pi(0)pi(0) cross-sections has been analysed in terms of isospin amplitudes. The reconstructed invariant-mass distributions of the pi pi, He-3 pi and (3)He2 pi systems provide hints on the role of nucleon resonances in the 3 pi production process.

  • Excitation of the Roper resonance in single- and double-pion production in nucleon-nucleon collisions
  • 2008
  • Ingår i: European Physical Journal A. - : Springer Science and Business Media LLC. - 1434-6001 .- 1434-601X. ; 35:3, s. 317-319

    • In most investigations the Roper resonance is sensed only very indirectly via complex partial-wave analyses. We find indications for its excitation in the invariant n pi(+) mass spectrum of the pp -> np pi(+) reaction at M approximate to 1360 MeV with a width of approximate to 150 MeV . The values fit very favorably to the most recent phase shift results as well as to the observations at BES. In the near-threshold two-pion production pp -> pp pi(0)pi(0) , where the Roper excitation and its subsequent decays via the routes N* -> Delta pi -> N pi pi and N* -> N sigma are the only dominant processes, we find its direct decay into the N sigma channel to be the by far dominating decay process -in favor of a monopole excitation of the Roper resonance.

  • ISOSPIN DECOMPOSITION OF pp -> NN pi pi CROSS SECTIONS : DO WE SEE A SIGN OF Delta(1600) EXCITATION IN THE nn pi(+)pi(+) CHANNEL?
  • 2009
  • Ingår i: International Journal of Modern Physics A. - 0217-751X .- 1793-656X. ; 24:2-3, s. 450-453
  • Tidskriftsartikel (refereegranskat)abstract
    • The two-pion production in pp-collisions has been investigated in exclusive measurements from threshold up to T-p = 1.36 GeV. Total and differential cross sections have been obtained for the channels pn pi(+) pi(0), pp pi(+) pi(-), pp pi(0)pi(0) and also nn pi(+)pi(+). For intermediate incident energies T-p > 1 GeV, i.e. in the region, which is beyond the Roper excitation but at the onset of Delta Delta excitation the total pp pi(0)pi(0) cross section falls behind theoretical predictions by as much as an order of magnitude near 1.2 GeV, whereas the nn pi(+)pi(+) cross section is a factor of five larger than predicted. A model-unconstrained isospin decompostion of the cross section points to a significant contribution of an isospin 3/2 resonance other than the Delta(1232). As a possible candidate the Delta(1600) is discussed.

    • The CELSIUS-WASA setup is used to measure the 3π0 decay of η mesons produced in pp interactions with beam kinetic energies of 1.36 and 1.45 GeV. The efficiency-corrected Dalitz plot and density distributions for this decay are shown, together with a fit of the quadratic slope parameter α yielding α = −0.026 ± 0.010(stat) ± 0.010(syst). This value is compared to recent experimental results and theoretical predictions.

  • Mapping potential location for bilberry picking with remote sensing, local field data andphone application
  • 2023
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • The aim of the study was to create a practical method for identifying potential locations for bilberry picking with help of remote sensing, local field data and phone application to support the development of the local berry value chain. Local field data w as collected 2021 and 2022 and consisted 503 and 525 plots from a study area of circa 25x45km in Västerbotten, Sweden. The potential for bilberry production was evaluated by measuring the shrub cover and amount of raw berries. Wall to wall remote sensing d ata included a Sentinel 2 image from same summer, airborne laser scanning data from 2020 and other map products. We created classification models for bilberry shrub and yield using both logistic regression (2 classes) and ordinal regression (3 classes) mod els using 2021 data, and validated and calibrated models with 2022 data. Predictor variables consisted of spectral metrics from satellite data; structural metrics from laser data; existing raster maps of tree species, stand attributes, site index, soil moi sture and land use classes. The 2 class models performed better than three class models, delivering the AUC 0.73, overall accuracy 0.83 and kappa value 0.51 for best bilberry shrub model and 0.75, 0.77 and 0.50 respectively for best bilberry yield model. T he best models included both laser based structural metrics describing e.g canopy closure and spectral metrics, but also e.g. volume of pine, soil moisture and site index were found significant predictor variables. Calibration of the models improved annual predictions and the validation of the 2021 raster maps with 2022 data produced similar AUC, OA, and kappa values for bilberry yield (0.73, 0.74 and 0.46), but lower for bilberry shrub (0.61, 0.68 and 0.24). A dedicated phone application was developed duri ng the project, which was used both for collecting the field data and for presenting the potential locations of berry yields. Local berry maps can help berry pickers easier to find the berries in forest landscape and therefore support local berry value cha in. This study is part of the FAIRCHAIN project, which has received funding from the European Union’s funding programme H2020 research and innovation programme under grand agreement 101000723.

  • Antimicrobial resistance in colonizing group B Streptococci before the implementation of a Swedish intrapartum antibiotic prophylaxis program.

  • Tidskriftsartikel (refereegranskat)abstract
    • The prevalence of antibiotic resistance and their genetic determinants in colonizing group B streptococci (GBS) sampled in a Swedish nationwide survey was examined. In five GBS isolates (1.3%), kanamycin/amikacin resistance and the presence of the aphA-3 gene was identified. Three of these isolates carried the aad-6 gene and were streptomycin-resistant. Screening with kanamycin and streptomycin 1,000-μg disks enabled a rapid and easy detection of these isolates. In all, 312/396 (79%) GBS were tetracycline-resistant and 95% of the examined isolates harbored the tetM gene. Among the 22 (5.5%) GBS resistant to erythromycin and/or clindamycin, the ermB gene was detected in nine isolates (41%) and erm(A/TR) in ten isolates (45%). A high level of erythromycin and clindamycin resistance with minimum inhibitory concentrations (MICs) >256mg/L was found in four serotype V isolates that harbored ermB. The erythromycin/clindamycin resistance was distributed among all of the common serotypes Ia, Ib, II, III, IV, and V, but was not present in any of the 44 serotype III isolates associated to clonal complex 17. Screening for penicillin resistance with 1-μg oxacillin disks showed a homogenous population with a mean inhibition zone of 20mm. A change in the present oxacillin breakpoints for GBS is suggested.

  • Exclusive measurements of pp -> d pi(+)pi(0) : Double-pionic fusion without ABC effect
  • 2010
  • Ingår i: Physics Letters B. - : Elsevier BV. - 0370-2693 .- 1873-2445. ; 684:2-3, s. 110-113
  • Tidskriftsartikel (refereegranskat)abstract
    • Exclusive measurements of the reaction pp -> d pi(+)pi(0) have been carried out at T-p = 1.1 GeV at the CELSIUS storage ring using the WASA detector. The isovector pi(+)pi(0) channel exhibits no enhancement at low invariant pi pi masses, i.e. no ABC effect. Therefore this most basic isovector double-pionic fusion reaction qualifies as an ideal test case for the conventional t-channel Delta Delta excitation process. Indeed, the obtained differential distributions reveal the conventional t-channel Delta Delta mechanism as the appropriate reaction process, which also accounts for the observed energy dependence of the total cross section.

  • Ingår i: Physics Letters B. - : Elsevier BV. - 0370-2693 .- 1873-2445. ; 649:2-3, s. 122-127
  • Tidskriftsartikel (refereegranskat)abstract
    • The cross section for direct neutral and charged three pion production in pp interactions was measured at excess energies in the range 160–216 MeV. That comprises the first measurement of the pp→ppπ0π0π0 reaction and the direct comparison with the pp→ppπ+π−π0 process. The experiment was performed above the η meson production threshold and the cross section could be directly normalized to the cross section of the pp→ppη reaction, with the η decaying into 3 pions. Since the same final states are selected, the measurement has a low systematical error. The measured cross section ratio σ(pp→ppπ+π−π0)/σ(pp→ppπ0π0π0) is compared to predictions of dominance of different isobars in the intermediate state.

    • The cross section for the pd→3Heηπ0 reaction has been measured at a beam energy of 1450 MeV using the WASA detector at the CELSIUS storage ring and detecting one 3He and four photons from the decays of the two mesons. The data indicate that the production mechanism involves the formation of the Δ(1232) isobar. Although the beam energy does not allow the full peak of this resonance to be seen, the invariant masses of all three pairs of final particles are well reproduce dby a phase space Monte Carlo simulation weighted with the p-wave factor of the square of the π0 momentum in the 3He π0 system.

  • WNT5A-mediated β-catenin-independent signalling is a novel regulator of cancer cell metabolism.

  • Ingår i: Carcinogenesis. - : Oxford University Press (OUP). - 0143-3334 .- 1460-2180. ; 35:4, s. 784-794
  • Tidskriftsartikel (refereegranskat)abstract
    • WNT5A has been identified as an important ligand in the malignant progression of a number of tumours. Although WNT5A signalling is often altered in cancer, the ligand's role as either a tumour suppressor or oncogene varies between tumour types and is a contemporary issue for investigators of β-catenin-independent WNT signalling in oncology. Here, we report that one of the initial effects of active WNT5A signalling in malignant melanoma cells is an alteration in cellular energy metabolism and specifically an increase in aerobic glycolysis. This was found to be at least in part due to an increase in active Akt signalling and lactate dehydrogenase (LDH) activity. The clinical relevance of these findings was strengthened by a strong correlation (P < 0.001) between the expression of WNT5A and LDH isoform V in a cohort of melanocytic neoplasms. We also found effects of WNT5A on energy metabolism in breast cancer cells, but rather than promoting aerobic glycolysis as it does in melanoma, WNT5A signalling increased oxidative phosphorylation rates in breast cancer cells. These findings support a new role for WNT5A in the metabolic reprogramming of cancer cells that is a context- dependent event.

  • Exclusive measurement of the pp -> nn pi(+)pi(+) reaction at 1.1 GeV

  • Tidskriftsartikel (refereegranskat)abstract
    • First exclusive data for the pp -> nnp(+)pi(+) reaction have been obtained at CELSIUS with the WASA detector setup at a beam energy of T(p) - 1.1 GeV. Total and differential cross-sections disagree with theoretical calculations, which predict the Delta Delta excitation to be the dominant process at this beam energy. Instead, the data require the excitation of one of the nucleons to a higher-lying Delta state, preferably the Delta(1600)P(33), to be the leading process.

For intermediate incident energies T-P > 1GeV, i.e. in the region which is beyond the Roper excitation but at the onset of Delta Delta excitation, the total pp pi(0)pi(0) cross section falls behind theoretical predictions by as much as all order of magnitude near 1.2 GeV, whereas the nn pi(+)pi(+) cross section is a factor of five larger than predicted. An isospin decomposition of the total cross sections exhibits a s-channel-like energy dependence in the region of the Roper excitation as well as a significant contribution of an isospin 3/2 resonance other than the Delta(1232). As possible candidates the Delta(1600) and the Delta(1700) are discussed. (C) 2009 Elsevier B.V. All rights reserved.

    • Mitt i skogen en bra bit ifrån allfarvägarna bedrivs en mycket omfattande handels- och affärsverksamhet. Konsumenter dras till Ullared och Gekås för att göra storköp och för att fynda varor av olika slag. Ullared och Gekås är ett fenomen som väcker nyfikenhet och frågan är varför det har blivit på detta viset? Vad är det för speciellt med Gekås och Ullared som förklarar att affärsverksamheten blivit så framgångsrik och fortsätter att utvecklas?

  • Hållbar framtid : en seminarieserie om hållbart företagande
  • 2015
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • Under 2012 och 2013 genomfördes fyra seminarier under huvudrubriken Hållbartföretagande som ett samarrangemang mellan Borås Tidning och Högskolani Borås. Uppmärksammade och inflytelserika företagsledare och samhällsaktöreri regionen föreläste om sina erfarenheter av verksamhetsutveckling och uppfattningaroch tolkningar av innebörden av begreppet hållbar utveckling. Föreläsningarnaföljdes av paneldiskussioner och frågor och kommentarer från seminariedeltagarna.Seminarierna dokumenterades och följdes upp med personliga intervjuer iform av sju porträtt med fokus på uppfattningar om hållbar utveckling och vilkautmaningarna är för samhälle och företag. De sju beskrivningarna och porträttenhar sedan tillsammans med intryck och observationer vid seminarierna legattill grund för fyra kapitel författade av gruppen bakom seminarieserien. MikaelLöfström, universitetslektor i företagsekonomi, skriver om gränser för hållbartföretagande, Karin M. Ekström, professor i företagsekonomi, om innebördenoch betydelsen av möten, Stefan Eklund, chefredaktör på Borås Tidning, omden digitala människan och Björn Brorström, professor i företagsekonomi, omden egentliga innebörden av hållbar utveckling. Därefter ombads författaren ochjournalisten Göran Greider att skriva ett slutord baserat på samtliga texter ochutifrån egna perspektiv på hållbar utveckling.Alla dessa delar är samlade i rapporten Hållbar framtid. Den publiceras i Högskolani Borås rapportserie Vetenskap för profession, vars syfte dels är att spridakunskap om resultat av pågående och avslutad forskning vid högskolan, dels medverkatill debatt om förhållningssätt till utbildning och forskning och högskolorsoch universitets roll och ansvar för en gynnsam samhällsutveckling.Denna rapport kommer förhoppningsvis att ligga till grund för diskussionerkring innebörden och nödvändigheten av hållbar utveckling i en bred bemärkelse.

  • Alcohol intake and risk of non-Hodgkin lymphoma in men and women
  • 2004
  • Ingår i: Cancer Causes and Control. - : Springer Science and Business Media LLC. - 0957-5243 .- 1573-7225. ; 15:10, s. 1067-1076
  • Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
    • OBJECTIVE: The effect of alcohol intake on risk of NHL is unclear. We therefore conducted a population-based case-control study to examine the association between alcohol and NHL risk. METHODS: 613 NHL cases and 480 population controls in Sweden reported their average consumption of beer, wine, and liquor 2 years before the study. Unconditional logistic regression was used to estimate the odds ratios (OR) and corresponding 95% confidence intervals (CI) for associations between alcohol intake and NHL risk. RESULTS: Intake of total alcohol, beer, wine, or liquor was not associated with risk of overall NHL. There was no difference in risk of NHL among those who habitually consumed above 19.1 g of ethanol per day, compared to those who consumed on average 0-2.2 g of ethanol per day (OR = 1.2 (95% CI: 0.8, 1.7); Ptrend = 0.29). However, the association was significantly positive among males (OR = 1.8 (95% CI: 1.1, 2.9); Ptrend = 0.06). Total alcohol, beer, wine, or liquor intake was not associated with any major histopathologic subtype of NHL examined, apart from an association between high wine consumption and increased risk of chronic lymphocytic leukemia. CONCLUSIONS: Alcohol does not appear to be a major etiologic factor for overall NHL, nor its common subtypes.

  • Dietary factors and risk of non-hodgkin lymphoma in men and women
  • 2005
  • Ingår i: Cancer Epidemiology, Biomarkers and Prevention. - 1055-9965 .- 1538-7755. ; 14:2, s. 512-20
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: The incidence of non-Hodgkin lymphoma (NHL) has increased worldwide in recent decades. Diet could influence NHL risk by modulating the immune system, although evidence is limited. We did a population-based case-control study to determine whether differences in diet were associated with NHL risk. METHODS: A total of 597 NHL cases and 467 population controls in Sweden completed a semiquantitative food frequency questionnaire evaluating their dietary habits 2 years before the interview. Unconditional logistic regression was used to estimate the odds ratios (OR) and corresponding 95% confidence intervals (95% CI) for associations between food intake and risk of NHL. RESULTS: High consumption of dairy products and fried red meat was associated with increased risk of NHL. The OR of NHL for individuals in the highest quartile compared with the lowest quartile of dairy intake was 1.5 (95% CI, 1.1-2.2; P(trend) = 0.003). The OR for the highest versus lowest quartile of fried red meat intake was 1.5 (95% CI, 1.0-2.1; P(trend) = 0.02). In contrast, high consumption of fruits and vegetables was associated with reduced risk of NHL, particularly follicular lymphoma, among women but not men. Compared with the lowest quartile of vegetable intake, the OR of follicular lymphoma among women in the highest quartile of vegetable intake was 0.3 (95% CI, 0.1-0.7; P(trend) = 0.002). CONCLUSIONS: The positive associations of NHL risk with dairy products and fried red meat and the inverse association with fruits and vegetables suggest that diet affects NHL risk and could explain the increase of some histopathogic subtypes.

  • Nutrient intake and risk of non-Hodgkin's lymphoma
  • 2006
  • Ingår i: American Journal of Epidemiology. - : Oxford University Press (OUP). - 0002-9262 .- 1476-6256. ; 164:12, s. 1222-1232
  • Tidskriftsartikel (refereegranskat)abstract
    • The mechanisms through which diet may influence the development of non-Hodgkin's lymphoma (NHL) are unclear but can be better understood by examining associations between nutrient consumption and NHL risk. Between 2000 and 2002, 591 NHL cases and 460 population-based controls in Sweden completed a semiquantitative food frequency questionnaire. Unconditional logistic regression was performed to estimate odds ratios and 95% confidence intervals for associations with nutrient intake; all statistical tests were two sided. Dietary intake of most macronutrients was not associated with risk of NHL or its common subtypes. Consumption of omega-3 or marine fatty acids was associated with decreased risk of NHL and chronic lymphocytic lymphoma, and dietary fiber was associated with lower risk of all subtypes examined. When the highest and the lowest quartiles of marine fat intake were compared, the odds ratio for NHL risk was 0.6 (95% confidence interval: 0.4, 0.9), ptrend=0.03; for dietary fiber intake, the corresponding odds ratio was 0.5 (95% confidence interval: 0.3, 0.7), ptrend<0.001. Dietary consumption of beta-carotene or alpha-tocopherol was associated with lower NHL risk, whereas intake of calcium or retinol was associated with increased NHL risk. Nutrients that affect inflammation, vitamin D activity, oxidative DNA damage, or DNA methylation may be associated with risk of NHL.
