The estimated degree of carotid stenosis is decisive for the selection of patients who would benefit from surgical treatment. Carotid thrombendarterectomy is recommended in patients with symptomatic > or = 80 procent internal carotid artery stenosis (ECST method). Many vascular centers now often rely entirely on duplex ultrasonography to select the patients for carotid surgery. The results of a re

Hemopoietic stem cells (HSCs) are maintained at relative quiescence by the balance between the positive and negative regulatory factors that stimulate or inhibit their proliferation. Blocking the action of negative regulatory factors may provide a new approach for inducing HSCs into proliferation. A variety of studies have suggested that TGF-beta negatively regulates cell cycle progression of HSCs

The long-term shoreline evolution at Hai Hau Beach in the Red River Delta, Vietnam was simulated using the one-line model GENESIS (Hanson, 1989). Dikes were modelled as seawalls and the sediment continuity equation in GENESIS was modified to take into account the offshore transport of fine-grained sediment. The model performed well, reproducing the magnitude and trend of the long-term shoreline ch

Weekly resource use data for local wound treatment was collected from a clinical survey (138 patients). Annual costs were calculated from the weekly resource usage multiplied by unit costs and published epidemiological prevalence data for Sweden. The average weekly cost was 101 euro, though it differed depending by ulcer size. The total direct annual cost of venous leg ulcers in Sweden could be es

Recent work from several laboratories has demonstrated that proteolytic mechanisms significantly contribute to the molecular interplay between Streptococcus pyogenes, an important human pathogen, and its host. Here we describe the identification, purification and characterization of a novel extracellular cysteine proteinase produced by S.pyogenes. This enzyme, designated IdeS for Immunoglobulin G-

We present here a tribute to Hemming Ivar Virgin (October 19, 1918-October 19, 2005), a pioneer in Swedish plant photobiology, developer of a University, and an outstanding educator.

Cellulose, a polysaccharide consisting of beta-1,4-linked glucose, is the major component of plant cell walls and consequently one of the most abundant biopolymers on earth. Carbohydrate polymers such as cellulose are molecules with vast diversity in structure and function, and a multiplicity of hydrolases operating in concert are required for depolymerisation. The bacterium Rhodothermus marinus,

ABSTRACT. This paper addresses the question of whether ‘main clause infinitival datives’ in Russian should be analyzed as oblique or ‘quirky’ subjects, in contrast to another type of subject-like datives in Russian, ‘I-nominals’. In particular, it examines a claim to this effect made by Moore and Perlmutter in a paper in Natural Language and Linguistic Theory (2000). By comparing the datives in qu

We prove that smooth solutions of the Degasperis-Procesi equation have infinite propagation speed: they loose instantly the property of having compact support.

In hydrological models for water resources management and planning, the model output or design quantities are functions of the input data and a number of parameters that are essentially stochastic processes or random variables. The task of uncertainty analysis is to estimate the uncertainty characteristics of the model output in terms of the uncertainties in the input, model parameters and initial

The work is composed of three parts: - (1) An overview of the concept moisture deign with regard to service life. (this report) - (2) A practical application of service life analysis applied to frost damage, based on materials testing. (this report) - (3) A theroretical analysis of methods for service life design of concrete and concrete structures exposed to internal frost damage (Report TVBM-04/
