   Sammanfattning : BackgroundGastrointestinal (GI) symptoms are commonly reported in a normal population. Mostly, the symptoms are of benign cause but occasionally the symptoms can be signs of a more harmful disease. In general, it is difficult to distinguish whether the reported symptoms are caused by a benign (functional) or organic (i.e. LÄS MER

   Författare :Oskar Lundgren; Margareta Kristenson; Peter Garvin; Gerhard Andersson; Lena Jonasson; J. David Creswell; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : There is strong evidence for the observation that psychological risk factors, such as depressive symptoms, hopelessness, and anxiety are associated with higher risk of developing coronary heart disease (CHD), and also contribute to a worse prognosis among CHD patients. Much less is known about psychological resources, such as Mastery, and their role in cardiovascular medicine. LÄS MER

4. 3. Passivity & Breakdown of Super Duplex Stainless Steel : Studied with Electrochemical & Synchrotron Techniques

   Författare :Marie Långberg; Jinshan Pan; David Lindell; Ulf Kivisäkk; Edvin Lundgren; Sannakaisa Virtanen; KTH; []
   Nyckelord :Passive film; duplex stainless steel; synchrotron X-ray reflectivity; X-ray diffraction; X-ray fluorescence; hard X-ray Photoelectron emission microscopy; X-ray Photoelectron spectroscopy; Electrochemical impedance; Kemi; Chemistry;

   Sammanfattning : Super duplex stainless steel consists of two phases: austenite and ferrite, and is a highly corrosion resistant material, with a wide range of applications. The corrosion resistance of stainless steels is determined by the performance of a spontaneously formed thin Cr oxide rich film with a thickness of 1-3 nm. LÄS MER

7. 5. Sex and stress steroid modulation of GABA mediated chloride ion flux in rat CNS

   Författare :Jessica Strömberg; Per Lundgren; Torbjörn Bäckström; David Haage; Esa Korpi; Umeå universitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; allopregnanolone; chloride ion uptake; patch-clamp; 3beta-steroids; kinetic parameters; rat brain; Obstetrics and gynaecology; Obstetrik och gynekologi;

   Sammanfattning : Background: Sex and stress steroids are metabolized to 3a-hydroxy-pregnane-steroid metabolites such as allopregnanolone (Allo) and tetrahydrodeoxycorticosterone (THDOC). Allo and THDOC are neuroactive steroids that are metabolized in the brain and act in brain as potent positive GABAA receptor function modulators. LÄS MER
