The number of leads needed in clinical electrocardiography depends on the clinical problem to be solved. The standard 12-lead ECG is so well established that alternative lead systems must prove their advantage through well-conducted clinical studies to achieve clinical acceptance. Certain additional leads seem to add valuable information in specific patient groups. The use of a large number of lea

To address the targeting of G protein-coupled receptors to caveolae-related lipid rafts (CLR), we studied the human B2 (B2R) and B1 (B1R) bradykinin receptor subtypes in HEK293 cells. CLR were enriched on the basis of their unique buoyant density and composition of cholesterol, caveolin-1, and flotillin-1 but not clathrin. CLR contained B2R and B1R as determined by both receptor immunoblotting and

The use of molecular clusters as a basis of molecular single-electronic systems is considered experimentally and theoretically. The Langmuir-Blodgett formation and scanning tunneling microscope study of structures with chemically different cluster molecules is described. I-V curves and control curves of molecular single-electron transistors based on various single molecules were studied at room te

Using a recombinant mini-laminin-332, we showed that truncation of the three C-terminal amino acids of the gamma2 chain, but not of the C-terminal amino acid of the beta3 chain, completely abolished alpha3beta1 integrin binding and its cellular functions, such as attachment and spreading. However, a synthetic peptide mimicking the gamma2 chain C-terminus did not interfere with alpha3beta1 integrin

1. Climate warming increases the cover of deciduous shrubs in arctic ecosystems and herbivory is also known to have a strong influence on the biomass and composition of vegetation. However, research combining herbivory with warming is largely lacking. Our study describes how warming and simulated herbivory affect vegetation, soil nutrient concentrations and soil microbial communities after 10-13 y

To test whether the arrangement of fibre types in the human muscle (m. vastus lateralis) from clinically healthy and young males can be regarded as random, fascicles at different parts of the muscle and with different fibre type proportions were studied. The randomness of the arrangement of fibre types was assessed by the number of enclosed fibres in a fascicle and, on the basis of a model, tested

Oxygen toxicity is thought to be an important factor involved in development of bronchopulmonary dysplasia (BPD) in the very preterm infant. Glutathione (GSH) plays a major role in the antioxidant defense system in the preterm lung and there are theoretical implications that N-acetylcysteine (NAC) treatment could improve its function. The purpose of this study was to investigate whether NAC treatm

Purpose – This paper aims to contribute to the tactical and operational decision making of manufacturing and logistics operations by providing novel insights into modelling and simulation, based on complex adaptive systems (CAS). Design/methodology/approach – The research approach is theoretically based on CAS with agent-based modelling (ABM) as the implementation method. A case study is presented

Although very often used, the concept of sustainable development has not yet been perceived pragmatically. Due to its process nature, in this paper, we argue that sustainable development is a process in which the essential feedback loops, or Viability Loops as we name them, in the system in question are kept healthy and functional. This process deals with evolutionary changes with the end point no

The dry reaction between SO2 and limestone has been investigated at low temperatures. The study was focused on the wet-dry scrubbing application. Parameters investigated included: temperature: 313–353 K, SO2 concentration: 50–4000 ppm, oxygen concentration: 0–9 percent, carbon dioxide concentration: 0–10 percent, relative humidity 0–92 percent, limestone panicle diameter: 4–100 microns, and limest

In this paper, the transversal diffusion coefficient D of CO2 dissolved molecules through the wall of a hydrated cellulose fiber was approached, from the liquid bulk diffusion coefficient of CO2 dissolved molecules modified by an obstruction factor. The porous network between the cellulose microfibrils of the fiber wall was assumed being saturated with liquid. We retrieved information from previou

Two-particle correlations of direct photons were measured in central (208Pb+208Pb collisions at 158A GeV. The invariant interferometric radii were extracted for 100

All guidelines recommend short-acting inhaled beta 2-adrenoceptor agonists as the first-line drugs in acute asthma attacks and inhaled corticosteroids as the drugs of choice when regular daily treatment is needed. Short-acting inhaled beta 2-adrenoceptor agonists are not effective in reducing nocturnal awakenings because of their short duration of action. In addition there has been an intense deba

The post-burn immune dysfunction predisposes patients to sepsis and multiple organ failure leading to increased mortality. HIV infection also results in a depressed immune response. The combination of burn injury and HIV might therefore lead to an increased morbidity and mortality as compared to non-HIV infected burn patients. Twenty burn patients and 10 healthy volunteers were included in a prosp
