    Sammanfattning : By virtue of certain design features, bone anchored metal implants can be made to elicit a strong initial osteogenic response, i.e., the amount of bone formed. LÄS MER

  3. 2. Effects of nitric oxide on gastric acid secretion in human gastric mucosa : functional and morphological studies

    Författare :Anna Berg; Gunnar Flemström; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Hydrochloric acid (HCI) is secreted in high amounts by parietal cells in the human gastric mucosa and the resulting low pH constitutes an important factor for creating a suitable environment for the digestion. The normal gastric mucosa is equipped with an arsenal of protective mechanisms against the extreme chemical environment which the gastric acid creates. LÄS MER

  4. 3. The role of gastrin and extracellular matrix proteins in proliferation and differentiation of gastric epithelial cells

    Författare :Karin Tømmerås; Andrés Uribe; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The mechanisms regulating the proliferation and differentiation processes that give rise to and maintain the gastric epithelium have not yet been completely elucidated.In the present studies, in vitro models were established and the influence of growth factors and extracellular matrix proteins on these processes were investigated.

  5. 4. Epiphora : impact on vision, outcome of lacrimal surgery and investigations with ultra-high-frequency ultrasound

    Författare :Elin Bohman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Epiphora is a common condition that often receives little attention. Excessive tear production creates an irregular and ever-changing ocular surface, affecting refraction and reducing vision. However, in a standard test situation the visual acuity is seldom affected, leading to the misinterpretation that epiphora is a minor problem. LÄS MER
