   Sammanfattning : Radionuclide therapy requires patient-specific planning of the absorbed dose to target volumes, in most cases tumours, in order to achieve an expected biological effect, taking into account that the absorbed doses to normal organs and tissues should be kept as low as reasonably achievable. Therefore, the calculation of absorbed doses has to be as accurate as possible. LÄS MER

3. 22. Inflammation and cortisol response in coronary artery disease

   Sammanfattning : Atherosclerosis is characterized by a chronic inflammation, involving autoimmune components, in the arterial wall. An increase in proinflammatory activity relative to anti-inflammatory activity is considered to cause a progression of the disease towards plaque instability and risk of atherothrombotic events, such as acute coronary syndrome (ACS).

   Sammanfattning : The aims of this study were to document the levels of cobalamin, folate, methylmalonic acid (MMA) and total homocysteine (tHcy) in serum and their relations to symptoms, clinical findings, and other factors in order to improve the possibilities of detecting early deficiency of vitamin B12 or folate, and to study the effects of cobalamin and folic acid treatment over a three-year period. The study population consisted of a 20% random sample of persons 70 years or older living in Älvkarleby in mid-Sweden. LÄS MER

   Sammanfattning : Vitamin E in food, polyunsaturated fatty acids (PUFAs) and lipid lowering treatment with statins have been found to decrease the risk for cardiovascular disease (CVD) and cardiac death. However, clinical trials revealed no beneficial effect of intake of alpha-tocopherol alone. LÄS MER
