- We conducted a two-stage genome-wide association study of pancreatic cancer, a cancer with one of the lowest survival rates worldwide. We genotyped 558,542 SNPs in 1,896 individuals with pancreatic cancer and 1,939 controls drawn from 12 prospective cohorts plus one hospital-based case-control study. We conducted a combined analysis of these groups plus an additional 2,457 affected individuals and 2,654 controls from eight case-control studies, adjusting for study, sex, ancestry and five principal components. We identified an association between a locus on 9q34 and pancreatic cancer marked by the SNP rs505922 (combined P = 5.37 x 10(-8); multiplicative per-allele odds ratio 1.20; 95% confidence interval 1.12-1.28). This SNP maps to the first intron of the ABO blood group gene. Our results are consistent with earlier epidemiologic evidence suggesting that people with blood group O may have a lower risk of pancreatic cancer than those with groups A or B.

Journal article (peer-reviewed)abstract
- Many case-control studies have suggested that higher consumption of fruit and vegetables is associated with a lower risk or pancreatic cancer, whereas cohort studies do not support such an association. We examined the associations of the consumption of. fruits and vegetables and their main subgroups with pancreatic cancer risk within the European Prospective Investigation into Cancer and Nutrition (EPIC). EPIC is comprised of over 520,000 Subjects recruited from 10 European countries. The present study included 555 exocrine pancreatic cancer cases after an average follow-up of 8.9 years. Estimates of risk were obtained by Cox proportional hazard models, stratified by age at recruitment, gender, and study center. and adjusted for total energy intake, weight, height, history of diabetes mellitus, and smoking status. Total consumption of fruit and vegetables, combined or separately, as well as subgroups of vegetables and fruits were unrelated to risk of pancreatic cancer. Hazard ratios (95% CI) for the highest versus the lowest quartile were 0.92 (0.68-1.25) for total fruit and vegetables combined, 0.99 (0.73-1.33) for total vegetables, and 1.02 (0.77-1.36) for total fruits. Stratification by gender or smoking status, restriction to microscopically verified cases, and exclusion of the first 2 years of follow-up (lid not materially change the results. These results from a large European prospective cohort Suggest that higher consumption of fruit and vegetables is not associated with decreased risk of pancreatic cancer. (C) 2008 Wiley-Liss, Inc.

Sediment reworking by marine benthic species from the Gullmar Fjord (Western Sweden): Importance of faunal biovolume
- 2007
-
In: Journal of Experimental Marine Biology and Ecology. - : Elsevier BV. - 0022-0981. ; 348:1-2, s. 133-144

Journal article (peer-reviewed)abstract
- In order to compare and quantify sediment reworking activities by different species/functional groups of macrofauna, a laboratory experiment was carried out with species from the Gullmarsfjord (Western Sweden). Monospecific communities of Amphiura filiformis, Echinocardium cordatum, Scalibregma inflatum and Abra nitida were introduced in experimental mesocosms, with identical densities (795 ind. m(-2)), for 10 days. Sediment reworking was studied by quantifying downward and upward movements of fluorescent inert tracers (luminophores). Luminophores with different colour were initially deposited both at the sediment surface and within the sediments. Population biomass and biovolume were also determined. Surface tracers reworking coefficients ranged from 0.6 to 2.2 cm(2) y(-1) and 0.9 to 4.1 y(-1), respectively for the biodiffusive-like and non-local transports. Calculated biodiffusive-like coefficient was between 1.0 and 2.3 cm(2) y(-1) for the deep tracers. For both tracers, the E. cordatum population presented the highest reworking coefficients. Among the morphological and/or ethological parameters that could determine overall patterns of reworking and differences between species, results have shown a direct relationship between the apparent biodiffusive mixing and the biovolume of the individuals (D-b=0.35 * Biovolume). This suggests that the biovolume-of macrofauna may allow a rough estimate of the biodiffusive-like reworking intensity of particles deposited on the sediment surface. (c) 2007 Elsevier B.V.

Capillary phenomena in liquid composite moulding
- 2007

Conference paper (peer-reviewed)abstract
- In liquid composite moulding, capillary phenomena take place as the fibre/air interface is progressively replaced by the fibre/resin interface. These effects are often neglected when computing the flow front progression into the fibre preform, because the surface tension of the resins is low. However, these are recognized to exert an influence on the final void content of the part. In this article, we present experimental results from unidirectional infiltration of an epoxy resin under constant flow rate into non-crimp fabrics. The inlet pressure rise is shown to deviate from linearity, indicating a progressive saturation. A multiphase flow approach is proposed to model infiltration, assuming saturation curves and relative permeability dependence on saturation based on soil science literature. Numerical results using a FEM code show trends that are in good qualitative agreement with experimental results. The interest and validity of this approach is then discussed.

Meat, eggs, dairy products, and risk of breast cancer in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort.
- 2009

In: The American journal of clinical nutrition. - : Elsevier BV. - 1938-3207 .- 0002-9165. ; 90:3, s. 602-612

Journal article (peer-reviewed)abstract
- BACKGROUND: A Western diet is associated with breast cancer risk. OBJECTIVE: We investigated the relation of meat, egg, and dairy product consumption with breast cancer risk using data from the European Prospective Investigation into Cancer and Nutrition (EPIC). DESIGN: Between 1992 and 2003, information on diet was collected from 319,826 women. Disease hazard ratios were estimated with multivariate Cox proportional hazard models. RESULTS: Breast cancer cases (n = 7119) were observed during 8.8 y (median) of follow-up. No consistent association was found between breast cancer risk and the consumption of any of the food groups under study, analyzed by both categorical and continuous exposure variable models. High processed meat consumption was associated with a modest increase in breast cancer risk in the categorical model (hazard ratio: 1.10; 95% CI: 1.00, 1.20; highest compared with lowest quintile: P for trend = 0.07). Subgroup analyses suggested an association with butter consumption, limited to premenopausal women (hazard ratio: 1.28; 95% CI: 1.06, 1.53; highest compared with lowest quintile: P for trend = 0.21). Between-country heterogeneity was found for red meat (Q statistic = 18.03; P = 0.05) and was significantly explained (P = 0.023) by the proportion of meat cooked at high temperature. CONCLUSIONS: We have not consistently identified intakes of meat, eggs, or dairy products as risk factors for breast cancer. Future studies should investigate the possible role of high-temperature cooking in the relation of red meat intake with breast cancer risk.

Journal article (peer-reviewed)abstract
- To examine the association of baseline and lifetime ethanol intake with cancer of the pancreas in the European Prospective Investigation into Cancer and Nutrition (EPIC). Included in this analysis were 478,400 subjects, of whom detailed information on the intake of alcoholic beverages at baseline and over lifetime was collected between 1992 and 2000. During a median follow-up time of 8.9 years, 555 non-endocrine pancreatic cancer cases were observed. Multivariate Cox proportional hazard models were used to examine the association of ethanol intake at recruitment and average lifetime ethanol intake and pancreatic cancer adjusting for smoking, height, weight, and history of diabetes. Overall, neither ethanol intake at recruitment (relative risk (RR) = 0.94, 95% confidence interval (CI) 0.69-1.27 comparing 30+ g/d vs. 0.1-4.9 g/d) nor average lifetime ethanol intake (RR = 0.95, 95% CI 0.65-1.39) was associated with pancreatic cancer risk. High lifetime ethanol intake from spirits/liquor at recruitment tended to be associated with a higher risk (RR = 1.40, 95% CI 0.93-2.10 comparing 10+ g/d vs. 0.1-4.9 g/d), but no associations were observed for wine and beer consumption. These results suggest no association of alcohol consumption with the risk of pancreatic cancer.
