  2. 6. The role of the mitochondrial membrane system in apoptosis : the influence of oxidative stress on membranes and their interactions with apoptosis-regulating Bcl-2 proteins

    Author : Martin Lidman; Gerhard Gröbner; Magnus Wolf-Watz; Philip Williamson; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bax; Bc-2; apoptosis; mitochondria; membranes; oxidized lipids; NMR; calorimetry; circular dichroism; biokemi; Biochemistry; fysikalisk kemi; Physical Chemistry;

    Abstract : Apoptosis is a crucial process in multicellular organisms in sculpting them, especially during embryogenesis. In addition, apoptosis is responsible for the clearance of harmful or damaged cells which can otherwise be detrimental to the organism. READ MORE

    Abstract : From January, 1988, to December, 1993, 113 patients with FIGO stage IA-IIC epithelial ovarian carcinoma were treated with postoperative radiotherapy. The median follow-up period was 74 months. Tumor recurrences were recorded in 33 cases (30%). The cancer-specific survival rate was 72%. READ MORE

  5. 8. Aspects of pathological apoptosis in the immature brain after hypoxia-ischemia

    Author : Ulrika Hallin; Göteborgs universitet; []
    Keywords : neonatal; rat; brain; hypoxia-ischemia; necrosis; apoptosis; calpain; caspase; Bcl-2; Bax; mitochondria; calcineurin.;

    Abstract : The cause of mechanisms underlying perinatal brain injury is not fully known, but it results in a wide variety of neurological impairments in the affected children. When injured, neurons of the newborn brain are prone to undergo programmed cell death, apoptosis, since this genetic program is normally activated in some cells during development of the nervous system, even in the perinatal period.

    Abstract : Malignant melanoma arises from the pigment producing melanocytes in epidermis and is the most aggressive type of skin cancer. The incidence of malignant melanoma is increasing faster than any other type of cancer in white population worldwide, with a doubling rate every 10-20 years. READ MORE
