  1. 21. Sex steroid effects on normal breast tissue

    Författare :Gunnar Söderqvist; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Estrogen receptor; progesterone receptor; proliferation; breast epithelialcells; mammary epithelium; sulfatase; 17 HSD; regional differences; sex steroids;

    Sammanfattning : In Sweden, it is estimated that about one million women are treated with estrogen/progestogen for contraception and hormone replacement therapy (HRT). The possibility of an increased cancer risk in target organs has been vividly discussed for many years. LÄS MER

  3. 22. Metastatic bone disease

    Författare :Rikard Wedin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :cytology; epidemiology; metastatic bone disease; pathologic fracture; prognosis; radiotherapy; skeletal metastasis; surgical therapy; survival; MIB; p53; ER; PgR;

    Sammanfattning : Aim: To evaluate epidemiology, prognosis and diagnostics in metastatic bone disease and identify risk factors for failure after operation for pathologic fracture. Patients: The study was based on patients treated for skeletal metastases, myeloma or lymphoma between 1986 and 1998 at the Oncology Service, Department of Orthopedics, Karolinska Hospital and on patients diagnosed with symptomatic skeletal metastases 1989-1994 in the Stockholm Region.

  4. 23. Magnetic resonance imaging in breast diagnosis

    Författare :Maria Kristoffersen Wiberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MRI; breast; triple diagnosis; FNAB; size; scintimammography.;

    Sammanfattning : MRI of the breast has, since the introduction of gadolinium contrast agents, been increasingly used in breast investigations. MRI has been found to have a high sensitivity but a low specificity in cancer detection. The aim of this thesis was to study and establish the role of MRI in the clinical diagnosis of breast lesions.

  5. 24. Luminescent molecular recognition of pathognomonic and aging associated protein aggregates

    Författare :Daniel Sjölander; Per Hammarström; Peter Nilsson; Uno Carlsson; Jan Johansson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Various protein inclusions have been recognized to be associated with aging and pathogenic conditions, such as in Alzheimer’s disease, Parkinson’s disease, Type 2 diabetes, and the prionoses Creutzfeldt-Jakob disease, Chronic wasting disease (CWD), and Mad cow disease. The causative transition of protein aggregation is the alteration in the conformation of the protein that renders the protein susceptible towards self-assembly. LÄS MER

  7. 25. Molecular aspects of post-Chornobyl and sporadic papillary thyroid carcinoma

    Författare :Andrii Dinets; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :papillary thyroid carcinoma;

    Sammanfattning : Papillary thyroid carcinoma (PTC) exhibits various molecular abnormalities, both when sporadic and radiation-related. PTC is still diagnosed in adult individuals who were younger than 18 years at the time of the Chornobyl accident in 1986 and lived within the contaminated area. LÄS MER
