Background The relationship between blood pressure levels and decline of cognition has been discussed previously, but little is known about the confounding effect of lifestyle factors, anti hypertensive treatment and disease in the elderly. Objective To examine the association between systolic (SBP) and diastolic (DBP) blood pressure, changes of DBP and SBP and hypertension (HT) on cognitive funct

Objective: To investigate the cerebral circulatory response to superimposed acute hypoxemia in growth-restricted fetuses with established brain-sparing flow (BSF) during basal conditions. Material and methods: 76 term fetuses suspected of growth restriction were exposed to Doppler velocimetry in the umbitical artery (UA) and middle cerebral artery (MCA), and in 38-39 cases also in Galen's vein (GV

BACKGROUND: The laparoscopic approach in antireflux surgery might have an impact on the patient's daily activities and well-being. METHODS: Sixty patients were randomized to laparoscopic or open 360 degrees fundoplication. Data were collected by questionnaires and interviews preoperatively, 1 month and 6 months after operation. RESULTS: Five patients in the laparoscopic group were converted to ope

Mutagenic/carcinogenic heterocyclic amines (HAs) are formed at low levels (ng/g) during heat processing of protein-rich food such as meat and fish. The complex matrix requires effective extraction and purification methods. Blue Chitin columns were used for the extraction of HAs from fried chicken fillets and the samples were analysed with LC-MS. Several HAs were identified at levels ranging from 0

Travel patterns among different socio-economic groups in Sweden are investigated. It is shown that elderly persons, persons with low incomes and women in general do not travel extensively. Middle-aged persons, persons with high incomes and men travel much farther. Cars are the dominant transportation mode for all population groups. Aeroplanes are used mostly by high-income earners and men, while p

In this letter, a novel frequency-multiplication device based on a three-terminal ballistic junction is proposed and demonstrated. A 100 nm-size, three-terminal ballistic junction and a one-dimensional (1-D), lateral-field-effect transistor with trench gate-channel insulation are fabricated from high-electron-mobility GaInAs/InP quantum-well material as a single device. The devices show frequency

This report presents the fifth and last experiment in a longitudinal study of text building behaviour at the Gymnasium level of a Swedish School. The series of experiments concerns natural language production as a means for the establishment of state attractors as well as their geometric space descriptions. The hypothesis tested during three years of instruction and learning is whether the evolvin

Selective modification of one (of three) tyrosine residue per enzyme monomer leads to inactivation of dUTPase of the retrovirus equine infectious anemia virus (EIAV). The substrate dUMP and the cofactor Mg2+protects against inactivation and modification, in agreement with the study onE. colidUTPase (Vertessyet al.(1994)Biochim. Biophys. Acta1205, 146-150). Amino acid analyses of nitrated dUTPases

Popular Abstract in Swedish I avhandlingen utvecklas en begreppsapparat som syftar till att utvidga vetenskapens möjligheter att studera människors formaliserade praktik i såväl religiösa som profana sammanhang. Begreppet ritual blir en term att se och tänka med. Författaren applicerar sin begreppsapparat på de medeltida isländska släktsagorna där skapandet av allianser mellan personer är ett viktTo make it possible to classify an action as a ritual act we need to know exactly what constitutes it. In this thesis I try, with the aid from literature of the field called ritual studies and the sagas of Icelanders, to sort out what these constituent elements best should consist of if we want to use the term ritual as an analytical tool in the production of knowledge with scientific criteria. Ri

A 0.5-liter optical HCCI engine firing a mixture of n-heptane (50%) and iso-octane (50%) with air/fuel ratio of 3 is studied using large eddy simulation (LES) and laser diagnostics. Formaldehyde and OH LIF and in-cylinder pressure were measured in the experiments to characterize the ignition process. The LES made use of a detailed chemical kinetic mechanism that consists of 233 species and 2019 re

Two photoproducts of DNA damage, i.e. cyclobutane pyrimidine dimers (CPDs) and 6-4 photoproducts (6-4PPs), induced by UV-B radiation in suspension-cultured tobacco cells were quantified by enzyme-linked immunosorbent assay (ELISA) with monoclonal antibodies. CPDs and 6-4PPs were induced in tobacco cells by UV-B radiation. Photorepair of CPDs was faster than that of 6-4PPs. UV-B radiation induces f
