  2. 1. Cancer and migration : epidemiological studies on relationship between country of birth, socio-economic position and cancer

    Author : Omid Beiki; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Country of birth; immigrants; breast neoplasm; uterine cervical neoplasm; endometrial neoplasm; ovarian neoplasm; prostatic neoplasm; testicular neoplasm; socio-economic position; incidence; survival; Sweden;

    Abstract : Background: Migrant studies offer a unique opportunity to analyze variation in disease occurrence due to background factors. The role of environmental and lifestyle exposures are of particular interest in cancer research, and migrant studies can be considered as "natural experiments" in epidemiological research. READ MORE

  4. 2. Molecular aspects of tumor development and treatment for small intestinal neuroendocrine tumors

    Author : Omid Fotouhi; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Small intestinal neuroendocrine tumors (SI-NETs) may cause symptoms due to excess secretion of hormones and peptides. The molecular mechanisms behind development of SINETs are not well understood. Copy number alterations, especially loss of chromosome 18q, have been reported and recently p27 mutations were implicated in SI-NET tumorigenesis. READ MORE

  5. 3. Data Driven Visual Recognition

    Author : Omid Aghazadeh; Stefan Carlsson; Jiri Matas; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Visual Recognition; Data Driven; Supervised Learning; Mixture Models; Non-Parametric Models; Category Recognition; Novelty Detection;

    Abstract : This thesis is mostly about supervised visual recognition problems. Based on a general definition of categories, the contents are divided into two parts: one which models categories and one which is not category based. We are interested in data driven solutions for both kinds of problems. READ MORE

  6. 4. Application of the Seismic Reflection Method in Mineral Exploration and Crustal Imaging : Contributions to Hardrock Seismic Imaging

    Author : Omid Ahmadi; Christopher Juhlin; Alireza Malehmir; Gilles Bellefleur; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Seismic reflection; Hardrock; Mineral exploration; Crustal imaging; Interpretation; Modeling; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Abstract : The seismic reflection method has been used extensively in mineral exploration and for imaging crustal structures within hardrock environments. In this research the seismic reflection method has been used and studied to address problems associated with hardrock settings. READ MORE

  7. 5. Studies on natural antisense RNAs and microRNAs

    Author : Omid Reza Faridani; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Regulatory RNAs are found in all kingdoms of life and involved in regulation of gene expression at various steps including RNA splicing, editing, stability, modification, export, translation and chromatin remodelling. A large number of regulatory RNAs have been described recently. READ MORE
