1. 21. Glömda gudstecken : från fornkyrklig dopliturgi till allmogens bomärken

   Sammanfattning : The pioneering academic research on Merchant Marks (also known as identity marks, personal marks, ownership marks, identification marks, Hausmarken, Hofmarken, Marques de Propriété, bomärken) was done by professor Homeyer (1870). Since 1870 there has been an ongoing debate among scholars whether Merchant Marks are simply formed by chance and coincidence, as stated by Rehnberg (1938, 1951), Scheffer (1957) and Nahlén (1992) or whether they are variations of Christian symbols, especially the cross, as stated by Sisson (1929) and Stevenson (1954).

3. 22. Mechanisms of HAMLET-induced cancer cell death

   Författare :Sonja Aits; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; alpha-actinin; prohibitin; alpha-lactalbumin; HAMLET; cancer; cell death; autophagy; focal adhesions; c-Myc; hexokinase; glycolysis;

   Sammanfattning : HAMLET, a complex of α-lactalbumin and oleic acid, preferentially kills cancer cells and is also effective in vivo. HAMLET causes apoptosis but cells die even if this pathway is inhibited. Thus, the role of autophagy, an alternative cell death pathway, was examined. LÄS MER

5. 24. Alpha-1-microglobulin: Innate defence against pathological oxidation

   Författare :Magnus Gram; Infektionsmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; alpha-1-microglobulin; pathological oxidation; hemoglobin; heme; radiation; oxidation; ROS; hemoglobin and heme antagonist; radical scavenger;

   Sammanfattning : Oxidative stress has been implicated as an important factor in the progression of many diseases. An imbalance in the redox-system may cause oxidation of cells and molecules, which might subsequently lead to tissue damage. LÄS MER

7. 25. Studies of transforming growth factor alpha in normal and abnormal growth

   Författare :Anna-Lotta Hallbeck; Åke Wasteson; Thomas Walz; Annelie Lindström; Carl-Henric Heldin; Linköpings universitet; []

   Sammanfattning : Regulation of growth is of fundamental importance for development of the organism and to maintain health. The induction of cell proliferation and matrix production are influenced by several different signaling systems, most importantly by growth factors. LÄS MER
