  2. 1. Assessment of patients with late diagnosis and missed opportunities in the Swedish HIV-1 epidemic

    Author : Johanna Brännström; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Discovered in 1983, with a possibility to diagnose since 1985, and with efficient treatment existing now for two decades, HIV-1 still ranks among the top ten causes of death globally. Approximately 40 million people are living with HIV-1 worldwide; almost half still not diagnosed. READ MORE

  5. 3. Molecular dissection of established and proposed members of the Op18/Stathmin family of tubulin binding proteins

    Author : Kristoffer Brännström; Martin Gullberg; Fredrik Ivars; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Op18 Stathmin; Sm16; tubulin; microtubule; schistosoma mansoni; Molecular biology; Molekylärbiologi;

    Abstract : My initial aim was a functional analysis of the conserved Op18/stathmin family of microtubule-regulators, which includes the ubiquitous cytosolic Op18 protein and the neural membrane-attached RB3 and SCG10 proteins. The solved X-ray structure has shown that these proteins form a complex with tubulin -heterodimers via two imperfect helical repeats, which result in two head-to-tail aligned heterodimers in a tandem-tubulin complex.

  6. 4. The impact of structural factors in colon and rectal cancer surgery

    Author : Fredrik Brännström; Ulf Gunnarsson; Pia Jestin; Peter Matthiessen; Arne Wibe; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : The aim of this thesis was to investigate the importance and effect of some key-structural factors on outcome of colorectal cancer surgery.Considerable improvements in the treatment of colorectal cancer, i.e. radiotherapy, chemotherapy and operative technique, have taken place since the beginning of the 80s.

  7. 5. Visual ecology of insect superposition eyes

    Author : Pär A Brännström; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Animal physiology; tiger beetle; hawkmoth; mayfly; insect; visual ecology; eye design; vision; compound eye; Djurfysiologi;

    Abstract : In the superposition compound eye each rhabdom (light sensitive unit) receives light through many ommatidial facets, while in the apposition compound eye every rhabdom receives light from a single facet. The superposition design increases photon capture, which is an advantage in dark environments. READ MORE
