  3. 2. Methods for early diagnosis of head and neck cancer

    Författare :Sushma Nordemar; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Head and neck; laminin5; cystic metastasis; ICM DNA-analysis; aneuploidy;

    Sammanfattning : Head and Neck squamous cell cancer (HNSCC) is the fifth most common malignancy in the western countries and in Sweden it comprises 2- 3% of all cancer cases. Alcohol and tobacco are known as principal etiological factors but other carcinogenic attributes i.e. viruses and bethel chewing have also been recognised. LÄS MER

  4. 3. Safety and efficacy of intracameral mydriatics in cataract surgery

    Författare :Björn Lundberg; Anders Behndig; Charlotta Zetterström; Umeå universitet; []
    Nyckelord :Ophtalmology; intracameral; mydriatics; pupil; cataract; phacoemulsification; lidocaine; phenylephrine; cyclopentolate; epinephrine; endothelial cell loss; Oftalmiatrik; oftalmiatrik; Ophtalmology;

    Sammanfattning : Background: In order to perform cataract surgery, adequate dilatation of the pupil is essential. This is traditionally achieved by preoperative topical mydriatic eye-drops, commonly cyclopentolate and phenylephrine. This routine has several disadvantages. First, the slow penetration through the cornea delays the onset of mydriasis. LÄS MER

  5. 4. Ploidy, cell proliferation and apoptosis in lymphoid malignancies : methodological and clinical aspects

    Författare :Magdalena Czader; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :image cytometry; confocal cytometry; DNA ploidy; cell proliferation; ;

    Sammanfattning : The DNA aneuploidy and proliferative activity have been previously shown to carry a clinical significance in Iymphoid malignancies. However, the application of these parameters is complicated by methodological difficulties. LÄS MER

  7. 5. Optimisation of human embryonic stem cell derivation and culture : towards clinical quality

    Författare :Susanne Ström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :hESC;

    Sammanfattning : For clinical grade human embryonic stem cell (hESC) lines, a robust derivation and culture system without any substances having animal origin would be optimal. The general aims of these studies have been to gradually improve our hESC derivation and cultures. LÄS MER
