The present study was designed to evaluate yoga's impact on blood pressure (BP) and quality of life (QOL) and on stress, depression and anxiety in patients with hypertension in a primary care setting. We conducted a multi-centre randomized controlled trial with follow-up after 12-week intervention completion. Adult primary care patients diagnosed with hypertension were randomly allocated to yoga o

The accuracy and precision of frameless neuronavigation as compared to conventional frame-based stereotaxy for implantation of deep brain stimulation (DBS) electrodes were studied in 14 patients with essential tremor. DBS electrodes were implanted bilaterally in the ventrolateral thalamus [ventrointermediate nucleus ( VIM)] in one procedure. Frameless neuronavigation was used on one side and the c

INTRODUCTION Based on historical data, a decline in sperm counts during the years 1940-1990 has been suggested and aetiologically linked to a concomitant increase in the incidence of testicular cancer. This study, focusing on possible changes in sperm parameters among young Swedish men, during the past 10 years, was specifically designed in order to answer the question of whether there is a contin

ABSTRACT Aims: To compare two versions of a questionnaire translated using forward-backward (FB) translation and dual-panel (DP) methodologies regarding preference of wording and psychometric properties. Methods: The Rheumatoid Arthritis Quality of Life instrument was adapted into Swedish by two independent groups using FB and DP methodologies, respectively. Seven out of thirty resulting items wer

Neutral photodissociation processes and non Franck-Condon effects in the N2 and O2 molecules induced by excitation with synchrotron radiation photons have been studied in the 15-35 eV region. Neutral dissociation processes have been studied by monitoring dispersed fluorescence from excited N and O atoms. The excited atoms are created through excitations to members of the molecular Rydberg seri

Popular Abstract in Swedish Staren i jordbrukslandskapet Under de senaste tre decennierna har staren (Sturnu's vulgari's) i likhet med många andra fågelarter knutna till jordbrukslandskapet minskat kraftigt i antal, både i Sverige och i stora delar av västra och norra Europa. Det finn's flera tänkbara förklaringar till detta, men eftersom jordbruket under samma tidsperiod genomgått stora förändriThe European Starling Sturnus vulgaris as many other farmland bird species has been declining during the last decades. The cause of these declines is generally believed to be changes with in agricultural methods affecting breeding and survival of birds. For starlings in Southern Sweden the amount of pasture in the landscape surrounding breeding colonies is the key factor. We found a positive relat

Popular Abstract in Swedish Många växtarter kan inte kolonisera kalkjordar och det är stora skillnader i artsammansättningen mellan kalkjordar och närliggande surare jordar. Detta beteende kallas ofta för kalkskyende och tycks orsakas av en oförmåga hos dessa växtarter att lösa och ta upp fosfat och järn ur kalkjordar. Kalkjordar innehåller mycket låga halter av järn och fosfat löst i marklösningeMany vascular plant species are unable to colonise calcareous sites, the floristic composition of adjacent limestone and acid silicate soils differing markedly. The inability of these 'calcifuge' species to establish themselves and grow on limestone soil appears to mainly be related to their low capacity for solubilising and absorbing phosphate and/or iron from such soils. Differences between calc

A limited Round Robin test has been carried out with different types of foot models. Eight laboratories carried out the tests. The foot models varied in sizes from 254 to 275 mm, representing boot sizes from 41 to 44. Tests with both a bare foot and sock were carried out at about +20 °C and 50% RH. The boots, a thin rubber and a winter boot, were tested at about +5 °C and 85% RH. The conditioning

Popular Abstract in Swedish I Sverige insjuknar årligen drygt 6000 kvinnor i bröstcancer. Antalet nyinsjuknade kvinnor i sjukdomen stiger något för varje år samtidigt som dödligheten minskar. En av orsaken till den minskade dödligheten är modern medicinsk behandling som idag kompletterar den kirurgiska behandlingen. Sjukdomsförloppet vid bröstcancer är mycket varierande beroende på tumörens utbredBackground: Treatment of primary breast cancer is individualised and adjuvant systemic treatment is delivered to most patients after surgery. Oestrogen receptor (ER) status and progesterone receptor status (PR) can define patients who would benefit from adjuvant endocrine therapy with tamoxifen (TAM) alone or as chemo-endocrine therapy. In spite of adjuvant treatment with TAM, some patients with h

Popular Abstract in Swedish Statistik handlar om att beskriva slumpmässiga händelser. Genom att bygga matematiska modeller för hur slumpen beter sig kan man beräkna hur troliga olika händelser är. Skilda ämnen har nytta av olika slags slumpmodeller, men slumpens lagar är universella! Därför kan en slumpmodell som utvecklats inom ett ämne senare visa sig användbar inom ett helt annat. Min avhandlinThis thesis explores models and algorithms in geostatistics and gene mapping. The first part deals with the use of computationally effective lattice models for inference of data with a continuous spatial index. The fundamental idea is to approximate a Gaussian field with a Gaussian Markov random field (GMRF) on a lattice, and then to conduct a bilinear interpolation of this at non-lattice location

Popular Abstract in Swedish Tvärströms mikrofiltrering är en teknik för att avskilja partiklar med en storlek på ungefär en mikrometer (en tusendel av en millimeter) från vätskor. Exempel på tillämpningar är avskiljning av jästceller från öl, och avskiljning av bakterier från mjölk. I mikrofiltrering används membran (filter) med porer med en storlek på 0.1 - 10 mikrometer. Mikrofiltreringsmembran Crossflow microfiltration is a technique to separate suspended particles (or cells or droplets) from liquids by use of a membrane that is permeable for the liquid but impermeable for the particles. The permeate flow drives particles to the membrane surface, where they may be deposited and form a fouling layer. To limit the growth of this fouling layer a flow is applied tangentially to the membrane

The work described in this thesis represents a biophysical approach, mainly using nuclear magnetic resonance (NMR) spectroscopy, to investigate the impact of magnesium ions on the EF-hand calcium-binding proteins calmodulin and calbindin D9k, as well as the dynamics of these proteins at low calcium levels. The x-ray structure of magnesium-saturated calbindin D9k shows a magnesium ion in only one o

Popular Abstract in Swedish Cholecystokinin (CCK) och gastrin är två välkända mag-tarmkanals hormoner. CCK namngavs efter sin förmåga att stimulera gallblåsans kontraktion och gastrin visade sig vara involverad i utsöndringen av magsyra. Allt eftersom antalet publikationer gällande dessa hormoner har vuxit har också en mångfald andra funktioner tillskrivits respektive hormon, bland annat har bäggeCholecystokinin (CCK) and the related hormone gastrin have been claimed to exert trophic effects in the pancreas and gastrointestinal tract. Two types of receptors for CCK and gastrin are known to exist, the CCK-A and the CCK-B receptor. They differ in their affinty for CCK and gastrin. The CCK-A receptor has about 500 times higher affinity for sulfated than for non-sulfated CCK and gastrin, while

A reduced-order through-flow program has been developed at the Lund Institute of Technology. The goal of the work was to develop and verify a program suitable for scientific studies of coaxial turbines. The program has built-in capability for multiple choked stages, and turbine cooling, as well as flexible modules for state, losses, deviation, and blockage. The code uses Matlab [trademark] as a pl

Disturbances in the pressure homeostasis of the middle ear (ME) system cause a pressure gradient across the tympanic membrane lessen the effectiveness of sound transmission and may be associated to development of chronic ME disease. An equipment for continuous direct pressure measurements was developed and was found to be accurate, base-line stabile and portable. Long term pressure measurements an

An energy system that relies on fossil fuel is not sustainable. Emissions, such as carbon dioxide, nitric oxide and corpuscles, affect the climate and pollute the air. Furthermore, the supply of oil, coal and natural gas is located a few places worldwide, which can give rise to geopolitical conflicts for access to these areas. This is not a local issue for Tjörn, nor even a national issue for Swed

Popular Abstract in Swedish Deformerbara speglar som används i teleskop är förhållandevis små med en diameter på 10-30 cm, med undantag av ett fåtal. Den största deformerbara spegeln som är integrerad i ett teleskop idag, har en diameter på 911 mm och återfinns i Large Binocular Telescope. I designen för E-ELT har en deformerbar spegel med en diameter på dryga 2 m inkluderats och GMT har ett antalIt is attractive to integrate a large deformable mirror for adaptive optics into an astronomical telescope rather than using relay optics within an auxiliary instrument. However, the resulting large deformable mirror can be expensive, particularly for extremely large telescopes. We have pursued a low-cost approach using force actuators connected to the back of the deformable mirror through suction

Colonization consists of two parts, a dispersal phase followed by establishment and reproduction at a new site. Dispersal behaviour influences survival and the access to resources and mates of individuals and is thus closely linked to an organism's fitness. The dispersal ability of two collembolan species, Protaphorura armata and Folsomia fimentaria, was determined in a laboratory experiment. The
