The time course of relaxation under isometric and isotonic conditions was studied in preparations of rat portal vein which maintained regular phasic contractions in solutions with increased [K-+] and [Ca-2+]. It was found that the smooth muscle during isotonic lengthening was able to carry the afterload for a period of time which was longer than expected from the control isometric response. The di
Abstract in German Die Verkürzung der Untersuchungszeiten bei der klinischen Magnetresonanztomographie (MRT) bietet für den Patienten den Vorteil einer angenehmeren und schnelleren Untersuchung und erhöht gleichzeitig den Patientendurchsatz. Dies erfordert schnelle und robuste Aufnahmetechniken, welche beispielsweise auch bei der Aufnahme bewegter Organe oder für atemangehaltene Messungen eingeset
Cerebral dysfunction without corresponding structural pathology has been reported in brain imaging studies of violent offenders. Biochemical markers in the CSF reflect various types of CNS pathology, such as blood-brain barrier dysfunction (CSF/S albumin ratio), infectious or inflammatory processes (IgG and IgM indices), neuronal or axonal degeneration (CSF-tau protein) and synaptic de- or regener
This paper explores the technical feasibility of five Advanced Driver Assistance System (ADAS) functions to contribute to road traffic safety, to reach stated European (EU) and national road traffic safety targets. These functions - enhanced navigation, speed assistance, collision avoidance, intersection support and lane keeping - were selected from previous research as adequate substitutes for in
The purpose of this study was to investigate patients' experiences of care in connection with hip fracture. The care process was examined through non-participant observation, informal field interviews and healthcare records. The findings showed that many factors in the healthcare services directly or indirectly influence patients' perceptions of the quality of care. Some of these factors may depen
Stress-related exhaustion is an increasingly focused phenomenon, although scientifically not yet fully conceptualised. This is perhaps partly due to the fact that the distinction between exhaustion and other already established concepts, such as depression, is not clear. This study explores whether exhaustion can be differentiated from depression and anxiety, by means of introducing the SF-36 vita
Mechanisms involved in the islet adaptation to insulin resistance were examined in mice of the C57BL/6J strain challenged with a high-fat (58%) diet for 8 weeks. Basal hyperglycemia commenced after 1 week, whereas hyperinsulinemia evolved after 8 weeks. Glucose elimination after an intravenous glucose challenge (1 g/kg) was significantly delayed after 1, 4, and 8 weeks on the high-fat diet compare
Phosphorus-31 nuclear magnetic resonance (NMR) spectra (103.2 MHz) were obtained from rabbit portal vein, urinary bladder, and taenia coli smooth muscle. The muscles were mounted isometrically as strips in a horizontal probe and superfused with oxygenated medium at 23 degrees C. Under these conditions the preparations could remain in a stable metabolic state for at least 24 h. The resonances obser
Ray-tracing simulations of mistuned sagittal diffractive - refractive X-ray lenses (DRXL) are presented. In this article, firstly the characteristic aberrations for various types of crystal misalignments within one-crystal and four-crystal DRXLs are considered, and the sensitivity of such an optical system to the mutual misalignment of its components is discussed. The simulations reveal that a DRX
Artikeln diskuterar några möjliga feministiska förhållningssätt till de religionsfilosofiska positionerna realism och non-realism. Artikeln ifrågasätter därefter positionernas dualistiska förutsättningar avseende existens och sanning och ger ett konstruktivt språkfilosofiskt förslag till hur man kan förstå förhållandet mellan språk och verklighet, där det inte längre blir nödvändigt att åberopa re
Background: The expression of gene batteries, genomic units of functionally linked genes which are activated by similar sets of cis- and trans-acting regulators, has been proposed as a major determinant of cell specialization in metazoans. We developed a predictive procedure to screen the mouse and human genomes and transcriptomes for cases of gene-battery-like regulation. Results: In a screen tha
What did make Europe's development different from that of other parts of the world?
