1. 1. Carotid Vessel Wall Thickness and Echogenicity : In the ULSAM study

   Författare :Martin Wohlin; Lars Lind; Johan Sundström; Samar Basu; Stefan Agewall; Uppsala universitet; []
   Nyckelord :Medicine; Epidemiology; Medicin;

   Sammanfattning : In this thesis the common carotid artery intima media thickness in nearly 500 elderly men is independently associated with insulin sensitivity, measured by the gold standard hyperinsulinemic euglycemic clamp test (paper 1), to both COX- and cytokine mediated inflammation independently of other markers of inflammation, oxidative stress and antioxidant status (paper 2) and also to the alleles of the apolipoprotein gene independently of lipid levels and cardiovascular risk factors (paper 3). The echogenicity of the carotid intima-media complex measured as grey scale median predicts mortality independently of common carotid artery intima-media thickness, prior cardiovascular disease and cardiovascular risk factors (paper 4).

3. 2. Clinical-epidemiological studies on cutaneous malignant melanoma : A register approach

   Författare :Johan Lyth; John Carstensen; Christer Lindholm; Hans Starkhammar; Håkan Olsson; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Melanoma; early detection; population-based; registers; time trends; survival; prognostic factors; tumour thickness; stage at diagnosis; level of education; socioeconomic status; healthcare costs;

   Sammanfattning : The incidence of cutaneous malignant melanoma (CMM) is steadily increasing. Most of the patients have thin CMM with a good prognosis and a 5-year survival of about 90%. The prognosis is highly related to tumour thickness and clinical stage at diagnosis. LÄS MER

4. 3. Nitrate, Nitrite and Nitric Oxide in Gastric Mucosal Defense

   Författare :Joel Petersson; Lena Holm; Jon Lundberg; Mia Phillipson; Matthew Grisham; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dietary nitrate; mucus gel layer; mucosal blood flow; mucus thickness; laser-Doppler flowmetry; mucosal damage; intra-vital microscopy; mucosal permeability; Physiology; Fysiologi;

   Sammanfattning : The human stomach normally contains high levels of bioactive nitric oxide (NO). This NO derives from salivary nitrate (NO3-) that is converted to nitrite (NO2-) by oral bacteria and thereafter non-enzymatically reduced in the acidic gastric lumen to NO. LÄS MER

5. 4. Helicobacter pylori and Gastric Protection Mechanisms : An in vivo Study in Mice and Rats

   Författare :Johanna Henriksnäs; Lena Holm; Lars Engstrand; Erik Persson; Lars Fändriks; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; mucus gel layer; mucosal blood flow; mucus thickness; intra-vital microscopy; laser-Doppler flowmetry; pH-sensitive microelectrode; nitric oxide; Helicobacter pylori; bicarbonate secretion; mouse model; Fysiologi; Physiology; Fysiologi;

   Sammanfattning : The stomach is frequently exposed to hazardous agents and to resist this harsh environment, several protective mechanisms exist. Of special interest is the gastric pathogen Helicobacter pylori which causes gastritis, ulcers and cancer but the mechanism leading to these diseases are still unclear. However it is very likely that H. LÄS MER

7. 5. Arterial stiffness and risk factors for cardiovascular disease in young adults

   Författare :Ulrika Fernberg; Anita Hurtig-Wennlöf; Maria Fernström; Bo Fernhall; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular disease; atherosclerosis; arterial stiffness; pulse wave analysis; intima media thickness; cardiorespiratory fitness; physical activity; body composition; young adults;

   Sammanfattning : Atherosclerosis is a complex, chronic vessel wall disease that often leads to severe and acute cardiovascular diseases (CVD), such as myocardial infarction and stroke. CVD are the most common cause of death, both globally and in Sweden. LÄS MER
