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

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

Several tumors secrete insulin-like growth factors (IGFs) for autocrine growth stimulation and protection from apoptosis. However, the mechanisms responsible for tumor growth in renal cell carcinoma (RCC) are unclear. In this study the biological role of exogenous IGFs in two malignant RCC cells (Caki-2 and SK-RC-52) were investigated in vitro, and compared to the breast cancer cell line MCF-7. IG

BACKGROUND AND PURPOSE: It is unclear whether stroke in patients with spontaneous dissection of the cervical internal carotid artery (ICAD) is due to thromboembolism or impaired hemodynamics. This study investigated the mechanism of stroke in ICAD by examining brain imaging and cerebrovascular findings of such patients. METHODS: We retrospectively evaluated the prospectively collected brain CT, MR

I denna artikel diskuteras och problematiseras nordisk forskning med inriktning mot konsumtion och fattigdom. Då forskningen inom detta fält förekommer inom flera vetenskapliga discipliner beskrivs några centrala perspektiv. Härefter problematiseras befintlig forskning, såväl i förhållande till dess innehåll som till dess hitintills svaga etablering. Vidare ges förslag på utvecklingsmöjligheter.

A new palaeoenvironmental record of the post-glacial history of the southern Baltic Sea (~14 ka to present) is presented. During this period, large water level and salinity changes occurred in the Baltic Basin due to opening and closing of connections to the North Atlantic. Previous attempts to establish a detailed chronology for these palaeoenvironmental changes have been conducted mainly in coas

This work is the result of a course project in Embedded Systems. The goal was to implement a whee-slip control system on a LEGO car using a microcontroller. The car allows front-wheel or back-wheel driven configuration. Experimental results are presented for dry and wet surfaces.

BACKGROUND AND PURPOSE: To determine how a recently proposed clinical stroke subclassification corresponds to specific findings on computed tomography (CT) and magnetic resonance imaging (MRI) of the brain. METHODS: Two hundred twenty-eight patients with first-ever stroke were divided into four clinical subgroups: (1) total anterior circulation syndrome: both cortical and subcortical symptoms from

The radial nerve may not function in association with fractures of the humeral shaft. There are various opinions about the causes and treatment. We report a case of complete rupture of the radial nerve after a fracture of the proximal shaft of the humerus. The nerve injury was treated with grafting and tendon transfer. Here we discuss diagnoses and treatments including neurobiological aspects of n

A polyion-surfactant ion complex salt, cat-HECDS, has been synthesised, consisting of cationic hydroxyethyl cellulose w th dodecylsulfate counterions. Ternary phase diagrams have been established for aqueous mixtures of cat-HECDS with either the conventional surfactant NaDS or the polyelectrolyte cat-HECCl. Such mixtures represent the simplest possible aqueous mixtures of oppositely charged polyme

The variability in the morphology, modal number of chromosomes, TCR expression and functional reactivity of a CII-specific T-cell hybridoma at continuous subcultivation have been investigated. As the number of passages increased, besides the oval semiadherent cells (normal phenotype), fibroblast-like cells (transformed phenotype) were also observed. The two cell subpopulations differed in their ka

Background. It is well known that portacaval shunting ultimately leads to a decrease in liver volume and hepatic function, but the mechanism is uncertain. The aim of the present study was to evaluate the effect of portacaval shunting (PCS) upon the morphological changes that occur in the liver in rats after port caval. anastomosis. Materials and methods. Sixty-six male rats underwent either PCS (n

Bird migration was recorded by tracking radar and visual observation at 23 sites in the region of the Northwest Passage, between Baffin Island and Herschel Island in the Beaufort Sea. The studies took place during a ship-based expedition from 29 June to 3 September 1999. A total of 692 tracks (average duration 160 s) of bird flocks on postbreeding migration were recorded. Eastward migration was wi

The differential alterations of the spliceosomal UsnRNAs (U1, U2, U4, U5, and U6) were reported to be associated with cellular proliferation and development. The attempt was made in this study to analyze the metabolic pattern of the spliceosomal UsnRNAs during the development of pre-malignant lung lesions induced in experimental mice model system by benzo(a)pyrene (BP) and also to see how tea poly

Reflections on Danish and Scandinavian church archaeology focusing on three turningpoints, where new perspectives are introduced: Around 1950, 1980 and 2000. Implicit three periods are presented in the history of church archaeology, 1950-80, 1980-2000, and after 2000. The new perspectives are followed by new ways of illustrating the churches.
