The interventions of portable digital devices such as mobile telephones, mp3 players, PDAs and many others, have contributed to the formation of contemporary notions of space. The impact of these devices' mobility (informing the users' mobility) could even be paralleled to the shift from the effects of still photography to those of film in the 19th century. Especially important for the perspective

Recent experiments indicate that the external perturbations, related e.g. to high-amplitude shear oscillations of the surface of a quartz crystal microbalance sensor, may suppress binding of mesoscopic aggregates (e.g., polystyrene spheres, vesicles, large proteins, etc.) to the surface. Using a simple kinetic model, we derive equations making it possible to conceptually understand and to mathemat

A 5-year follow-up study of 476 type I adult diabetic patients previously studied cross sectionally revealed that, during the observation period, 19 patients died and 30 developed cardiovascular or renal disease, such as myocardial infarction (n = 8), cerebrovascular disease (n = 3), amputation (n = 6), and renal insufficiency (n = 13). The patients were registered by one and the most-severe event

Comparative genomic hybridization analysis has demonstrated that breast tumors from BRCA1 and BRCA2 germ-line mutation carriers contain a large number of chromosomal copy number gains and losses. A high regional copy number gain at 6q22-q24 was observed in one BRCA1 tumor, and fluorescence in situ hybridization analysis indicated a strong amplification of the MYB oncogene (15 copies of MYB compare

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

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

Hypothermia may contribute to vascular spasm during bypass surgery. The effect of cooling on the reactivity of the human coronary artery (CA), saphenous vein (SV) and internal mammary artery (IMA) was studied in vitro. In CA and IMA cooling diminished the resting tension and the contraction to potassium, noradrenaline and 5-hydroxytryptamine. In contrast, in SV the contraction to noradrenaline and

Radiocarbon-dated macrofossils are used to document Holocene treeline history across northern Russia (including Siberia), Boreal forest development in this region commenced by 10,000 yr B.P, Over most of Russia, forest advanced to or near the current arctic coastline between 9000 and 7000 yr B.P. and retreated to its present position by between 4000 and 3000 yr B.P. Forest establishment and retrea

The morphology, structure, and reactivity of vanadium oxide-decorated Pd(111) surfaces, which have been subjected to oxidation and reduction treatments, have been investigated by scanning tunneling microscopy (STM), high-resolution electron energy loss spectroscopy (HREELS), and high-resolution X-ray photoelectron spectroscopy (HR-XPS) with synchrotron radiation combined with ab initio density fun

Direct gene transfer to the adult brain is dependent on vectors that transduce non-dividing cells, such as lentiviral vectors. Another aspect of the development of gene therapy to the brain is the need for cell-specific transgene expression. Expression from vesicular stomatitis virus G-protein (VSV-G) pseudotyped lentiviral vectors has been reported to be mainly neuron specific in the brain. We co
