  • A fully integrated low-IF DVB-T receiver architecture
  • 2004
  • record:In_t: 2004 INTERNATIONAL SYMPOSIUM ON SYSTEM-ON-CHIP, PROCEEDINGS. - 0780385586 ; , s. 189-192
  • swepub:Mat_conferencepaper_t (swepub:level_refereed_t)abstract
    • We propose a fully integrated DVB-T receiver architecture for low cost CMOS implementation. The receiver uses a dual-IF architecture to cover the receive bands from 170 MHz to 862 MHz and a Low-IF of 4.57 MHz. Key performance values meet the DVB-T requirements with competitive performance (Sensitivity 72.5 dBm, Noise Figure 66 dB, Adjacent Channel Protection Ratio-ACPR=43dB, available SNR=28 dB) and suggest that low cost receivers are realistic in volume for the coming digital broadcasting systems.

  • Cancer among patients with diabetes, obesity and abnormal blood lipids: a population-based register study in Sweden.
  • 2012
  • record:In_t: Cancer Causes and Control. - : Springer Science and Business Media LLC. - 1573-7225 .- 0957-5243. ; 23:5, s. 769-777
  • swepub:Mat_article_t (swepub:level_refereed_t)abstract
    • OBJECTIVE: To study how the incidence of cancer is related to diabetes, obesity or abnormal blood lipids. METHODS: Diagnosis of diabetes, obesity or abnormal blood lipids was studied 0-10 years prior to the diagnosis of cancer in 19,756 cases of cancer and in 147,324 controls matched regarding age, sex and domicile. RESULTS: Diabetes was significantly more common prior to diagnosis in patients with liver, pancreatic, colon and urinary tract/bladder cancer and in patients with breast cancer diagnosed with diabetes 0-4 years prior to the cancer diagnosis. A lower risk of diabetes was seen in patients with prostate carcinoma among individuals with diabetes diagnosed 5-10 years prior to the cancer diagnosis. The findings remained after adjusting for obesity and high blood lipids. Obesity was significantly more common in patients with endometrial, colon and kidney cancer and with breast cancer above the age of 60 years in those where obesity was diagnosed close to the diagnosis of cancer. High blood lipids were significantly more common in patients with ovarian cancer and less common in patients with breast cancer. CONCLUSIONS: The study confirms some previous findings concerning comorbidity and cancer and highlights some new ones.

  • Epithelial and Stromal MicroRNA Signatures of Columnar Cell Hyperplasia Linking Let-7c to Precancerous and Cancerous Breast Cancer Cell Proliferation
  • 2014
  • record:In_t: Plos One. - : Public Library of Science (PLoS). - 1932-6203. ; 9:8
  • swepub:Mat_article_t (swepub:level_refereed_t)abstract
    • Columnar cell hyperplasia (CCH) is the earliest histologically identifiable breast lesion linked to cancer progression and is characterized by increased proliferation, decreased apoptosis and elevated oestrogen receptor alpha (ER alpha) expression. The mechanisms underlying the initiation of these lesions have not been clarified but might involve early and fundamental changes in cancer progression. MiRNAs are key regulators of several biological processes, acting by influencing the post-transcriptional regulation of numerous targets, thus making miRNAs potential candidates in cancer initiation. Here we have defined novel epithelial as well as stromal miRNA signatures from columnar cell hyperplasia lesions compared to normal terminal duct lobular units by using microdissection and miRNA microarrays. Let-7c were among the identified downregulated epithelial miRNAs and its functions were delineated in unique CCH derived cells and breast cancer cell line MCF-7 suggesting anti-proliferative traits potentially due to effects on Myb and ER alpha. MiR-132 was upregulated in the stroma surrounding CCH compared to stoma surrounding normal terminal duct lobular units (TDLUs), and overexpression of miR-132 in immortalized fibroblasts and in fibroblasts co-cultured with epithelial CCH cells caused substantial expression changes of genes involved in metabolism, DNA damage and cell motility. The miRNA signatures identified in CCH indicate early changes in the epithelial and stromal compartment of CCH and could represent early key alterations in breast cancer progression that potentially could be targeted in novel prevention or treatment schedules.

  • Multi-Decadal Changes in Tundra Environments and Ecosystems : Synthesis of the International Polar Year-Back to the Future Project (IPY-BTF)
  • 2011
  • record:In_t: Ambio. - : Springer Science and Business Media LLC. - 0044-7447 .- 1654-7209. ; 40:6, s. 705-716
  • swepub:Mat_article_t (swepub:level_refereed_t)abstract
    • Understanding the responses of tundra systemsto global change has global implications. Most tundraregions lack sustained environmental monitoring and oneof the only ways to document multi-decadal change is toresample historic research sites. The International PolarYear (IPY) provided a unique opportunity for such researchthrough the Back to the Future (BTF) project (IPY project#512). This article synthesizes the results from 13 paperswithin this Ambio Special Issue. Abiotic changes includeglacial recession in the Altai Mountains, Russia; increasedsnow depth and hardness, permafrost warming, andincreased growing season length in sub-arctic Sweden;drying of ponds in Greenland; increased nutrient availabilityin Alaskan tundra ponds, and warming at mostlocations studied. Biotic changes ranged from relativelyminor plant community change at two sites in Greenland tomoderate change in the Yukon, and to dramatic increasesin shrub and tree density on Herschel Island, and in subarcticSweden. The population of geese tripled at one sitein northeast Greenland where biomass in non-grazed plotsdoubled. A model parameterized using results from a BTFstudy forecasts substantial declines in all snowbeds andincreases in shrub tundra on Niwot Ridge, Colorado overthe next century. In general, results support and provideimproved capacities for validating experimental manipulation,remote sensing, and modeling studies.

  • Polygenic risk modeling for prediction of epithelial ovarian cancer risk
  • 2022
  • record:In_t: European journal of human genetics : EJHG. - : Springer Science and Business Media LLC. - 1476-5438 .- 1018-4813. ; 30:3, s. 349-362

    • Polygenic risk scores (PRS) for epithelial ovarian cancer (EOC) have the potential to improve risk stratification. Joint estimation of Single Nucleotide Polymorphism (SNP) effects in models could improve predictive performance over standard approaches of PRS construction. Here, we implemented computationally efficient, penalized, logistic regression models (lasso, elastic net, stepwise) to individual level genotype data and a Bayesian framework with continuous shrinkage, “select and shrink for summary statistics” (S4), to summary level data for epithelial non-mucinous ovarian cancer risk prediction. We developed the models in a dataset consisting of 23,564 non-mucinous EOC cases and 40,138 controls participating in the Ovarian Cancer Association Consortium (OCAC) and validated the best models in three populations of different ancestries: prospective data from 198,101 women of European ancestries; 7,669 women of East Asian ancestries; 1,072 women of African ancestries, and in 18,915 BRCA1 and 12,337 BRCA2 pathogenic variant carriers of European ancestries. In the external validation data, the model with the strongest association for non-mucinous EOC risk derived from the OCAC model development data was the S4 model (27,240 SNPs) with odds ratios (OR) of 1.38 (95% CI: 1.28–1.48, AUC: 0.588) per unit standard deviation, in women of European ancestries; 1.14 (95% CI: 1.08–1.19, AUC: 0.538) in women of East Asian ancestries; 1.38 (95% CI: 1.21–1.58, AUC: 0.593) in women of African ancestries; hazard ratios of 1.36 (95% CI: 1.29–1.43, AUC: 0.592) in BRCA1 pathogenic variant carriers and 1.49 (95% CI: 1.35–1.64, AUC: 0.624) in BRCA2 pathogenic variant carriers. Incorporation of the S4 PRS in risk prediction models for ovarian cancer may have clinical utility in ovarian cancer prevention programs.

  • Molecular and genetic diversity in the metastatic process of melanoma.
  • 2014
  • record:In_t: Journal of Pathology. - : Wiley. - 0022-3417 .- 1096-9896. ; 233:1, s. 39-50
  • swepub:Mat_article_t (swepub:level_refereed_t)abstract
    • Diversity between metastatic melanoma tumours in individual patients is known; however, the molecular and genetic differences remain unclear. To examine the molecular and genetic differences between metastatic tumours, we performed gene-expression profiling of 63 melanoma tumours obtained from 28 patients (two or three tumours/patient), followed by analysis of their mutational landscape, using targeted deep sequencing of 1697 cancer genes and DNA copy number analysis. Gene-expression signatures revealed discordant phenotypes between tumour lesions within a patient in 50% of the cases. In 18 of 22 patients (where matched normal tissue was available), we found that the multiple lesions within a patient were genetically divergent, with one or more melanoma tumours harbouring 'private' somatic mutations. In one case, the distant subcutaneous metastasis of one patient occurring 3 months after an earlier regional lymph node metastasis had acquired 37 new coding sequence mutations, including mutations in PTEN and CDH1. However, BRAF and NRAS mutations, when present in the first metastasis, were always preserved in subsequent metastases. The patterns of nucleotide substitutions found in this study indicate an influence of UV radiation but possibly also DNA alkylating agents. Our results clearly demonstrate that metastatic melanoma is a molecularly highly heterogeneous disease that continues to progress throughout its clinical course. The private aberrations observed on a background of shared aberrations within a patient provide evidence of continued evolution of individual tumours following divergence from a common parental clone, and might have implications for personalized medicine strategies in melanoma treatment.
