  2. 1. Effects of growth hormone on bone tissue in transgenic mice

    Author : Jonas Sandstedt; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Growth hormone; bone; ovariectomy; orchidectomy; growth; Interleukin-6; titanium; transgenic mice;

    Abstract : Growth hormone (GH) affect bone-tissue in both humans and rodents. Also sex steroids are important for growth and the maintenance of normal bone physiology. The specific aims of this study were to investigate how high levels of GH affects bone tissue in mice and to determine whether these effects are dependent on an intact gonadal function. READ MORE

  4. 2. Ethanol-mediated effects on astroglial cells in primary culture. With a focus on acute changes in intracellular Ca2+, cell volume, actin filaments, and gap junction coupling

    Author : Louise Adermark; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; astrocyte; BaCl2; cell swelling; fura-2; furosemide; ouabain; scrape loading; volume estimation;

    Abstract : The astroglial cells are abundant in the central nervous system (CNS), where they control and regulate the homeostasis of the extracellular milieu. A change in astroglial cell volume, mediated through activation of neuroactive substances or changes in osmolarity, leads to changes in the size and geometry of the extracellular space volume, which could affect the diffusion and concentration of neuroactive substances.

  5. 3. Properties of the endothelial cells and the glomerular barrier

    Author : Jenny Sörensson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Capillary permeability; kidney glomerulus physiology; isolated perfused kidney; endothelium; orosomucoid; charge; horseradish peroxidase; inflammation; proteoglycan; cAMP.;

    Abstract : The kidneys are vital organs that filter plasma to produce 180 liters of primary urine per day. Only 1% of this volume is excreted and the rest is reabsorbed. Naturally, such huge amounts of fluid must be well controlled to maintain the homeostasis, which is a prerequisite for life. READ MORE

  6. 4. Nephrotic syndrome causes selective damage to the glomerular charge or size barriers. Physiological mechanisms based onexperimental studies in the rat

  7. 5. Protective Responses to Freediving Reveal High-Altitude Tolerance

    Author : Pontus Holmström; Erika Schagatay; Angelica Lodin-Sundström; Harald K. Engan; Ola Eiken; Mittuniversitetet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acclimatization; Acute Mountain Sickness; Adaptation; Apnea; Breath-hold diving; Cardiovascular diving response; High-altitude; Hypoxia tolerance; Spleen; Acklimatisering; Andhållningsdykning; Anpassning; Apné; Kardiovaskulära dykresponsen; Hög höjd; Hypoxitolerans; Hög-höjdssjukdom; Mjälte; Syrebärande kapacitet;

    Abstract : High-altitude mountaineers - just as freedivers - are exposed to hypoxia. During freediving, the diving response leads to reduced oxygen consumption, and splenic contraction increases circulating hemoglobin concentration (Hb), which enhances freediving performance. READ MORE
