Analysis of ET-A and ET-B receptors using an isolated perfused rat lung preparation.

Aims and Methods: The pulmonary and vascular effects of endothelin-1 receptor activation were studied in isolated perfused and ventilated lung preparations from rat. The responses to endothelin-1 (ET-1) and the endothelin B (ETB) receptor agonist sarafotoxin 6c (S6c) were characterized using the endothelin A (ETA)-receptor antagonist FR 139317, the ETB-receptor antagonist BQ 788 and the combined E

Tissue-phantom ratios from percentage depth doses

When converting fractional (percentage) depth doses to tissue-phantom ratios, one must use a factor that accounts for the different source-to-point distances. Two minor correction factors are also involved. One is the ratio of total to primary dose at the two different distances from the source, for the same depth and field size. This factor is usually ignored. It was determined experimentally tha

Addition of cultured Schwann cells to tendon autografts and freeze-thawed muscle grafts improves peripheral nerve regeneration

The effects of addition of Schwann cells on peripheral nerve regeneration through a novel graft material-the tendon autograft-and a conventional freeze-thawed muscle graft, were studied in the rat sciatic nerve. Adult Schwann cell cultures were established from predegenerated nerves. The Schwann cells were added to the autologous grafts by coculture (tendon autograft) or injection (freeze-thawed m

Villa '95 : ett yt- och energisnålt enfamiljshus

Rapporten behandlar möjligheterna att med de bästa tekniklösningarna som finns i dag komma fram till hur en energieffektiv enfamiljsvilla bör utföras. Värmelagring med golvvärmesystem, extra isolerat övergolv, reglerbarhet, ekonomisk kalkyl.

Non-analog beta decay of Rb-74

The magnitude of the Coulomb mixing parameter delta (l)(IM) has been experimentally deduced, for the first time, for the B decay of Rb-74. Th, estimated magnitude is derived from the feeding of the non-analog first excited 0(+) state in Kr-74. The inferred upper Limit of 0.07% is small compared to theoretical predictions. The half-life was measured to be 64.90(9) ms. (C) 2001 Published by Elsevier

Predictors of lung function and its decline in mild to moderate COPD in association with gender: Results from the Euroscop study

Background: There is increasing appreciation of gender differences in COPD but scant data whether risk factors for tow lung function differ in men and women. We analysed data from 3 years follow-up in 178 women and 464 men with COPD, participants in the Euroscop Study who were smokers unexposed to inhaled corticosteroids. Methods: Explanatory variables of gender, age, starting age and pack-years s

A genome-wide association study for blood lipid phenotypes in the Framingham Heart Study

Background: Blood lipid levels including low-density lipoprotein cholesterol ( LDL-C), high-density lipoprotein cholesterol ( HDL-C), and triglycerides ( TG) are highly heritable. Genome-wide association is a promising approach to map genetic loci related to these heritable phenotypes. Methods: In 1087 Framingham Heart Study Offspring cohort participants ( mean age 47 years, 52% women), we conduct

Kollektiv kollaps i lagidrotter - En teoretisk ansats.

Termen ”kollektiv kollaps” förekommer relativt ofta på dagstidningarnas sportsidor, men inte i den idrottspsykologiska litteraturen. På grundval av beskrivningen av kollektiv kollaps i media föreslås följande definition: Kollektiv kollaps inträffar när en majoritet av spelarna i ett idrottslag plötsligt presterar under förväntad standard i en match av stor, ofta avgörande, betydelse trots en norma

The Politics of Social Networks : Interpersonal Trust and Institutional Change in Post-Communist East Germany

Popular Abstract in Swedish Hur förändras organisationer? Medan statsvetenskaplig ny-institutionell teori är mer inriktad på att förklara varför institutioner är seglivade och svåra att förändra, så antar ekonomisk organisationsteori att organisationer relativt enkelt anpassar sig till omgivningens krav. Det sociala nätverks-perspektivet fokuserar de strukturer av samarbete och tillit som utvecklaNew institutionalist approaches are inherently weak at accounting for institutional change. In this book, social network analysis is proposed as a key to institutional change. The social network perspective focuses emergent patterns of interpersonal interaction and the resulting ties of interpersonal trust. As a complement and contrast to both March and Olsen’s influential new institutionalist "lo

Hormonal regulation of phosphodiesterase 3B in adipocytes

Popular Abstract in Swedish I min avhandling har jag undersökt hur fosfodiesteras 3B (PDE3B) i fettväven styrs vid svar på två typer av hormoner nämligen, insulin och katekolaminer. Det senare innefattar hormoner så som adrenalin och nor-adrenalin. Varför är då detta intressant att veta? I Sverige och världen har mängden människor med fetma under de senaste åren ökat lavinartat, vilket är en stor Insulin induced activation of the cAMP degrading enzyme phosphodiesterase (PDE) 3B in adipocytes is important for insulin mediated inhibition of lipolysis. The aim of this thesis was to contribute with knowledge on the acute activation of PDE3B in response to insulin and catecholamines in adipocytes. The activation of PDE3B was investigated from three different perspectives namely; phosphorylation

Integrated life cycle design : application to concrete multi-dwelling buildings

This work examines the application of ILCD (Integrated Life Cycle Design), to Swedish concrete multi-dwelling buildings. The aim of the study is to look into methodological issues of ILCD and to present the fundamental attributes of dwelling buildings and how they relate to concrete as a structural material. Methods for prediction of two important life cycle attributes: the economy and energy use

A comparative study of two methods for determination of pH, exchangeable base cations, and aluminum

The ability to compare soil chemical data achieved by different chemical extraction methods is a necessity for an efficient long-term monitoring of soils and for comparisons of results from regional soil surveys with differing standard methods. This study compares two common, methods for analysis of soil chemical properties, the combination of soil extraction in 1.0 M NH4Cl and 1.0 M KCl and the s
