  1. 1. Intracranial Arachnoid Cysts. Epidemiology, Morphology and Surgical Outcome

    Författare :Katrin Rabiei; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Arachnoid cysts; Cyst morphology; Epidemiology; Headache; Surgical outcome;

    Sammanfattning : Background: Intracranial arachnoid cysts (AC) are malformations of the arachnoid membrane. They may cause symptoms, either by obstruction of the CSF flow or by compression of adjacent neural tissues. LÄS MER

  3. 2. The significance of sexuality and cyst formation in the life-cycles of four marine dinoflagellate species

    Författare :Rosa Figueroa; Enhet akvatisk ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cyst; Hydrobiology; akvatisk ekologi; marine biology; aquatic ecology; limnology; sexuality.; meiosis; Lingulodinium polyedrum; life-cyle; limnologi; Marinbiologi; Gymnodinium nolleri; Gymnodinium catenatum; Alexandrium catenella; dinoflagellates;

    Sammanfattning : Sexuality and cyst formation were studied in the marine dinoflagellate species Gymnodinium catenatum Graham, Gymnodinium nolleri Ellegaard ? Moestrup, Alexandrium catenella (Whedon et Kofoid) Balech, and Lingulodinium polyedrum (Stein) Dodge. The study included the morphological characterization of sexual stages and processes, the time and description of meiosis, the study of the length and regulation of the mandatory dormancy period of resting cysts, and the relationships among parental strains and cyst progeny at phenotypic and molecular levels.

  4. 3. Adrenoceptors and nerve growth factor. Effects of electro-acupuncture and physical exercise in rats with steroid-induced polycystic ovaries

    Författare :Luigi Manni; Göteborgs universitet; []
    Nyckelord :;

    Sammanfattning : Polycystic ovary syndrome (PCOS) is complex endocrine and metabolic disorder associated with ovulatory dysfunction, follicular cyst and hyperandrogenism. The abnormalities detected in PCOS have been attributed to primary defects in the hypothalamic-pituitary unit, the ovarian microenvironment, the adrenal gland, and the insulin/insulin-like growth factor (IGF)-1 metabolic regulatory system.

  5. 4. Phytoplankton defense mechanisms against grazing : the role of grazing infochemicals

    Författare :Veronica Lundgren; Edna Granéli; Takeshi Yasumoto; Aaron Barkoh; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Akvatisk ekologi; Aquatic Ecology;

    Sammanfattning : Many phytoplankton species have evolved a variety of different defenses to decrease losses from grazing; morphological features, changes in life-history/behavior, and production of toxins. These defenses may be associated with costs. Therefore, some phytoplankton only express the defense when needed, i.e. LÄS MER

  7. 5. Trophic factors, neuroprotection and spinal cord repair

    Författare :Johan Widenfalk; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :spinal cord injury; GDNF; GFRalpha; neurotrophin; VEGF; olfactory ensheathing glia; weight-drop injury; in situ hybridization;

    Sammanfattning : Background: There is no cure for paralysis. The only drug therapy presently in use, acute high-dose methylprednisolone, has only modest effects on outcome. There is therefore a great need for new therapies. LÄS MER
