A quantitative autoradiographic study of the heterogeneous activity distribution of different indium-111-labeled radiopharmaceuticals in rat tissues
In light of the increased interest in small scale dosimetry, this paper presents a quantitative autoradiographic method for evaluation of heterogeneous activity distribution in tissues. This was studied in rat tissues after administration of 111In-chloride, -oxine, -tropolone, 111In-labeled homologous blood cells and 111In-anti-CEA-F(ab')2, using quantitative whole-body autoradiography. Quantifica
The influence of finite cavities on the sound insulation of double-plate structures
Lightweight walls are often designed as frameworks of studs with plates on each side-a double-plate structure. The studs constitute boundaries for the cavities, thereby both affecting the sound transmission directly by short-circuiting the plates, and indirectly by disturbing the sound field between the plates. The paper presents a deterministic prediction model for airborne sound insulation inclu
Temporal and spatial variability of carbon cycling in a subarctic landscape
This thesis deals with the carbon balance in a subarctic landscape at different temporal and spatial scales. Its focus is mainly on the peatland and mountain birch forest (Betula pubescens ssp. czerepanovii) ecosystems within the Abisko area in northernmost Sweden. This is an area with a temperature close to the 0 OC mean annual isotherm. The area has during the last 30 years experienced a limited

Atmospheric transport of polybrominated diphenyl ethers and polychlorinated biphenyls to the Baltic sea
The atmospheric transport of polybrominated diphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) was compared by measuring concentrations in air and deposition on an island located in the central basin of the Baltic Sea. Median SigmaPBDE and SigmaPCB concentrations (gaseous + particle) were 8.6 and 7.4 pg m(-3), respectively. Airborne PCBs were mainly found in the gaseous phase, while most
Antigen and epitope specificity of anti-glomerular basement membrane antibodies in patients with Goodpasture disease with or without anti-neutrophil cytoplasmic antibodies
Goodpasture disease (GP) is defined by the presence of anti-glomerular basement membrane (anti-GBM) antibodies and rapidly progressive glomerulonephritis. Besides anti-GBM, many patients with GP produce anti-neutrophil cytoplasmic antibodies (ANCA). For elucidation of the pathophysiologic significance of ANCA in this setting, epitope and antigen specificity of the anti-GBM antibodies and antigen s

Analysis of Adaptation in Human Postural Control
Popular Abstract in Swedish För att vi människor ska kunna upprätthålla balansen och utföra rörelser behöver vi ett komplext styrsystem som kontinuerligt kontrollerar och samordnar kroppens rörelser. Detta styrsystem, som kallas postural kontroll, får sin information från synen, balanssinnet (vestibularisorganen), led-muskelsinnet (proprioception) och receptorer i huden (mekanoreceptorer). Om någoThe ability to obtain correct balance control information and adjust motor performance appropriately are essential elements in effective postural control. However, functional disorders may affect the reliability of receptor information and ability to carry out corrective motions needed to maintain balance. This emphasizes the importance of rapid and accurate adaptation processes that can optimize
Sex difference in the mechanical properties of the abdominal aorta in human beings
PURPOSE: A previous study has shown age- and sex-related differences in abdominal aortic compliance. In that study blood pressure determined by auscultation in the brachial artery was assumed to be equal to blood pressure in the abdominal aorta. To validate our findings we investigated the pressure-diameter (P-D) relationship of the abdominal aorta. METHODS: Diameter and pulsatile diameter change
Microbial biosensor for the analysis of 2,4-dichlorophenol
A flow injection cell-based biosensor was constructed for 2,4-dichlorophenol (DCP) analysis by using a Clark-type oxygen electrode as a transducer. A mixed bacterial culture capable to biodegrade DCP was immobilized between a Teflon membrane and a dialysis membrane and attached to the oxygen electrode. Optimization of the flow rate, the injection volume, the carrier buffer concentration, and pH wa

Nerve cell damage in mammalian brain after exposure to microwaves from GSM mobile phones.
The possible risks of radio-frequency electromagnetic fields for the human body is a growing concern for our society. We have previously shown that weak pulsed microwaves give rise to a significant leakage of albumin through the blood-brain barrier. In this study we investigated whether a pathologic leakage across the blood-brain barrier might be combined with damage to the neurons. Three groups e

A gene duplication led to specialized gamma-aminobutyrate and beta-alanine aminotransferase in yeast
In humans, beta-alanine (BAL) and the neurotransmitter gamma-aminobutyrate (GABA) are transaminated by a single aminotransferase enzyme. Apparently, yeast originally also had a single enzyme, but the corresponding gene was duplicated in the Saccharomyces kluyveri lineage. SkUGA1 encodes a homologue of Saccharomyces cerevisiae GABA aminotransferase, and SkPYD4 encodes an enzyme involved in both BAL
