  3. 2. Chemotactic factors in the human follicle at ovulation

    Författare :Eva Runesson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chemokine; follicle; gonadotropin; human; ovary; ovulation;

    Sammanfattning : Ovulation is initiated by the midcycle gonadotropin surge, which leads to a controlled degradation of the follicle wall ending in follicular rupture and oocyte extrusion. The gonadotropins triggers several biochemical and biophysical changes such as vascular alterations, increased proteolytic enzyme activity and leukocyte extravasation, within the preovulatory follicle.

  4. 3. Proteomics informed investigation of human hepatocytes and liver tissue

    Författare :Niklas Handin; Per Artursson; Peter Nygren; Tobias Sjöblom; Mårten Fryknäs; Pieter Annaert; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; human; liver; hepatocytes; proteomics; cellular stress; apoptosis; hepatotoxicity; 3D culture; spheroid; drug metabolism; drug toxicity; drug transport; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : A successful drug needs to display beneficial absorption, distribution, metabolism, excretion and toxicity (ADME-Tox) profile. It is therefore important to investigate these properties during the drug discovery process. LÄS MER

  5. 4. Nitric oxide : An ally in extracorporeal circulation?

    Författare :Vilyam Melki; Jan Borowiec; Örjan Friberg; Uppsala universitet; []

    Sammanfattning : Many complications associated with heart surgery are due to the negative effects of extracorporeal circulation (ECC). Some of these complications may be attributed to ECC-induced activation of inflammation and coagulation pathways. LÄS MER

  7. 5. Acupuncture in reproductive medicine. Applications in human assisted reproduction and aspects of clinical and experimental neuroendocrinology

    Författare :Elisabet Stener-Victorin; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; electro-acupuncture; blood flow impedance; circulation; uterine artery; in-vitro fertilization; oocyte aspiration; polycystic ovary syndrome; experimentally induced PCO; anovulation; gonadotropins; steroids; neuropeptides; b-endorphin; nerve growth factor; corticotropin-releasing factor.;

    Sammanfattning : The use of acupuncture in the area of reproductive medicine is relatively new, and it has been rather poorly investigated in the past. When muscle afferents are stimulated by acupuncture in somatic segments related to the innervation of the ovaries and the uterus, functional changes occur in the neural substrate that may influence reproductive function and result in peripheral, segmental and central effects.
