Background: The standard reference region (RR) for amyloid-beta (Aβ) PET studies is the cerebellar grey matter (GMCB), while alternative RRs have mostly been utilized without prior validation against the gold standard. This study compared five commonly used RRs to gold standard plasma input-based quantification using the GMCB. Methods: Thirteen subjects from a test–retest (TRT) study and 30 from a
A reliable assessment of the optical properties of atmospheric black carbon is of crucial importance for an accurate estimation of radiative forcing. In this study we investigated the spatio-temporal variability of the mass absorption cross-section (MAC) of atmospheric black carbon, defined as light absorption coefficient (σap) divided by elemental carbon mass concentration (mEC). σap and mEC have
The structural heterogeneity of tumor tissue can be probed by diffusion MRI (dMRI) in terms of the variance of apparent diffusivities within a voxel. However, the link between the diffusional variance and the tissue heterogeneity is not well-established. To investigate this link we test the hypothesis that diffusional variance, caused by microscopic anisotropy and isotropic heterogeneity, is assoc
The synthesis of deoxyribonucleoside triphosphates (dNTPs), building blocks of DNA, can be achieved by two different pathways in the cell. One is called de novo synthesis and the other is known as salvage pathway. The de novo pathway involves synthesis of dNTPs by utilizing basic molecules like sugars, amino acids, CO2, NH3, etc., while in the other pathway, dNTPs are formed by salvaging intra- or
A consecutive series of patients with all types of cervical hip fracture (both undisplaced and displaced) were randomised to osteosynthesis with Hansson hook-pins (n = 98) or AO-screws (n = 101). Background parameters, fracture type and reduction of the fracture did not differ significantly between the groups. Fifty-seven percent of the patients were operated on within 6 h of admission to hospital
OBJECTIVE: To evaluate the outcomes after fenestrated endovascular aortic repair (f-EVAR) in a tertiary European referral center. METHODS: All patients treated with commercially available custom-made f-EVAR between September 2002 and June 2007 were prospectively enrolled in a computerized database including co-morbidities and aneurysm morphology. Patients were retrospectively analyzed. Follow-up c

We assessed hepatocellular carcinoma (HCC) risk associated with smoking and alcohol consumption and their interactions, using both questionnaire data and objective serum biomarkers. Information on smoking and alcohol consumption was collected at baseline from 450,112 participants of the EPIC cohort, among whom 255 developed HCC after a median follow-up of 14 years. In a nested case–control subset
