    Sammanfattning : Ischemic stroke causes millions of deaths around the world each year, and surviving patients often suffer from long-term disability. Hundreds of promising drug candidates have been identified in animal models, but the clinical trials have repeatedly failed. Lack of methodological quality in the animal studies, e.g. LÄS MER

  3. 3. Effects of sex steroids and tamoxifen on VEGF in the breast

    Detta är en avhandling från Institutionen för biomedicin och kirurgi

    Sammanfattning : Sex steroid exposure constitutes a risk factor for breast cancer, but little is known about the effects of sex steroids on factors mediating angiogenesis, the development of new blood vessels, in normal and malignant breast tissue. In this thesis we have investigated the effects of estradiol, progesterone, and the nonsteroidal anti-estrogen tamoxifen on vascular endothelial growth factor (VEGF) and its receptors (VEGFR-1 and VEGFR-2) in normal human breast tissue, endothelial cells, and breast cancer.

    Sammanfattning : Several studies suggest profound effects on mood and cognition by neuroactive steroids. Estrogen alone or in combination with antidepressant drugs affecting the serotonin system has been used to treat mood disorders. On the other hand, progesterone is related to negative effects on mood and memory. LÄS MER
