Mass balance pharmacokinetics, with simultaneous blood sampling from an artery and the internal jugular vein, was used to characterize the cerebral uptake of ketamine, norketamine, and midazolam in normoventilated pigs. Intravenous injections of ketamine or midazolam decreased the cerebral blood flow (CBF) by one third, as measured by intermittent 133Xe washout. By means of pharmacodynamic models,

The ability of protein kinase C and casein kinase 2 substrate in neurons (PACSIN)/syndapin proteins to self-polymerize is crucial for the simultaneous interactions with more than one Src homology 3 domain-binding partner or with lipid membranes. The assembly of this network has profound effects on the neural Wiskott-Aldrich syndrome protein-mediated attachment of the actin polymerization machinery

"You can prove anything with statistics" is a well-known expression, and this might be true if the methods are not properly used and/or the results are not reviewed critically. This demands knowledge about statistical methodology and practice in critically analysis. However, it is not only the researcher that needs this kind of knowledge but also professionals in clinical practice who will be info

The use of multi-amplitude signaling schemes in wireless OFDM systems requires the tracking of the fading radio channel. The paper addresses channel estimation based on time-domain channel statistics. Using a general model for a slowly fading channel, the authors present the MMSE and LS estimators and a method for modifications compromising between complexity and performance. The symbol error rate

Seven Swedish peats of different degrees of humification were pyrolysed in a thermobalance at pressures in the range 1.0-4.0 MPa. The formation kinetics of the pyrolysis products were determined using the non-isothermal evaluation method. The sample size used was 1.0 g and the heating rate was 10 K min-1. Gas production was analysed by gas chromatography and the components were CO2, C2H4, C2H6, CH

We investigate the ground-state energy of the pi(-)p atom (pionic hydrogen) in the framework of QCD + QED. In particular, we evaluate the strong energy-level shift. We perform the calculation at next-to-leading order in the low-energy expansion in the framework of the relevant effective field theory. The result provides a relation between the strong energy shift and the pion-nucleon S-wave scatter

Background. The incidence of non-Hodgkin lymphoma and prevalence of obesity are increasing globally. A suggested positive association between obesity and risk of non-Hodgkin lymphoma has prompted us to investigate the relationship between body mass index (BMI) and risk of malignant lymphoma subtypes in a population-based case-control study. Methods: Telephone interviews were conducted with 3055 ca

hree different types of bituminous coal were subjected to microbial desulphurization in bench scale slurry reactors. Consecutive treatment with two microorganism species was used to test if different sulphur forms could be removed. The treatment started with the bacterium Thiobacillus ferrooxidans followed by the archaeon Acidianus brierleyi. Consecutive treatment did not desulphurize the three te

Popular Abstract in Swedish Huntingtons sjukdom (HS) är en ärftlig sjukdom som i första hand drabbar hjärnan. De områden som främst angrips är hjärnbarken, där till exempel människans kognitiva förmågor, personlighet och planeringsförmåga finns samt ett område inne i hjärnvävnaden som kallas striatum, där våra rörelser kontrolleras och korrigeras. Sjukdomen visar sig initialt oftast med diffusa syHuntington's disease (HD) is a neurodegenerative disease caused by a CAG-triplet expansion in the gene encoding the protein huntingtin. The disease typically starts in mid-life and progresses for 15-20 years. To date no effective treatment is available for curing the disease. HD primarily affects the striatum, cerebral cortex and hypothalamus. At later stages cell death is evident in the striatum

Due to variabilities in the material, the geometrical configuration, or the manufacturing properties, a structure that is designed to be spatially periodic cannot be exactly periodic. The presence of small irregularities in a nearly periodic structure may influence the propagation of the vibration field, the field being localised. A number of papers have addressed such localisation phenomena. This
