Distribution of preproatrial natriuretic peptide mRNA in rat brain detected by in situ hybridization of DNA oligonucleotides: enrichment in hypothalamic and limbic regions

The expression and distribution of mRNA encoding preproatrial natriuretic peptide (ppANP) in rat brain has been investigated by in situ hybridization of two 35S-labeled synthetic DNA oligonucleotides, based on a cDNA clone sequence that encodes rat ppANP. The highest relative concentrations of ppANP mRNA were detected in the medial preoptic hypothalamic nucleus ("anteroventral/third ventricle regi

Development and demonstration of 2D-LIF for studies of mixture preparation in SI engines

Laser-induced fluorescence (LIF) has been developed for visualization of fuel distribution fields in an operating spark-ignition (SI) engine. Since the standard research fuel iso-octane, does not yield a useful LIF signal a fluorescent additive was used. None of the commonly used seeds were found adequate. A seed not commonly used in this context, 3-pentanone, C2H5COC2H5, was chosen due to favorab

Computational Aeroacoustics Based on Large Eddy Simulation and Acoustic Analogies

The thesis presents a numerical method developed by the author and its applications for computing the generated sound by an unsteady flow field and its propagation. The full equations of motion for compressible and unsteady flows describe both flow field and sound generation and propagation. It is assumed that the flow variables can be decomposed into semi-compressible / incompressible components

12-14 week scan with emphasis on risk assessment for fetal structural malformations and fetal loss

Popular Abstract in Swedish Bakgrund I Sverige erbjuds samtliga gravida kvinnor ett rutinultraljud vid 18-20 graviditetsveckor. Syftet med undersökningen är att fastställa antalet foster, uppskatta graviditetslängd samt granska fosteranatomin för att upptäcka eventuella missbildningar. En del missbildningar kan man se med ultraljud, men långtifrån alla. Att redan under graviditeten känna till om The aim was to evaluate first trimester nuchal translucency (NT) measurement for detection and risk assessment of fetal malformations and fetal loss. 39 572 pregnant women were randomised to either a routine ultrasound scan at 12-14 weeks including NT measurement or to a routine scan at 18-20 weeks. Prenatal diagnosis of major congenital heart malformations was compared between the two groups. In

Cryo-TEM studies of DNA and DNA-lipid structures

Studies published between 2001 and 2005 that utilise cryogenic transmission electron microscopy as a tool for investigating solutions containing DNA with or without amphiphiles present are reviewed. DNA or oligonucleotides form complexes with amphiphilic molecules such as lipids, so-called lipoplexes, and the structures and morphologies are excellent objects to study by cryogenic transmission elec

Synthesis of chiral, amphiphilic, and water-soluble chiral macrocycles via urea formation.

A simple, efficient, and flexible procedure for the synthesis of chiral, amphiphilic, and water-soluble macrocycles is reported. Acylation of p-xylylenediamine with N-Fmoc-protected glycine, -aspartic acid, -glutamic acid, and -arginine, followed by removal of Fmoc-groups, gave amino acid:p-xylylene conjugate diamines, which were converted to ten macrocycles via stepwise urea formation using p-nit

Geriatrik är ett försummat ämne i svensk läkarutbildning "Äldreparadoxen" kräver rejäl satsning

A survey at all six medical faculties in Sweden in the spring 2004 showed that basic medical schooling (Medical School) only included an average of 59 full hours of geriatrics, with a fivefold variation between universities (19 to 106 hours). This is despite the fact that the need for geriatric skills in the health care sector is steadily increasing. A test of general knowledge in geriatrics just

Methodologies for model calibration to assist the design of a preparative ion-exchange step for antibody purification

This work proposes methodologies using a model-based approach to gain knowledge on and assist the development of an ion-exchange step in a protein purification process; the separation of IgG from a mixture containing IgG, insulin and transferrin. This approach is suitable for capture and intermediate steps in a process. Both methods involve four consecutive steps. Firstly, the retention of the dif

Southward migration and fuel deposition of Red Knots Calidris canutus

We compared the differences between spring and autumn in migration speed, fuelling rates and fuel loads of migrating Red Knots Calidris canutus. As a basis we used ringing data from Ottenby Bird Observatory, southeastern Sweden, collected 1948–2003, with morphometrical data from 1990–2003. Numbers ringed varied between 0 and 301 per year (average 56). Morphometrics, recoveries and recaptures of ri

Nationella diabetesregistret 1996-2003. Kvalitetsvärdering visar att diabetesvården har forbättrats

The Swedish National Diabetes Register presents results during the period 1996-2003. Quality of care data from more than 75,000 diabetic patients (2003) treated at medical departments and primary health care centres are evaluated concerning national goals of HbA1c < 6.5% and BP < 140/85 mm Hg, the prevalence of lipid treatment, smoking etc. The national goals of HbA1c and BP were reached with incr

Integrated modelling of two xenobiotic organic compounds

This paper presents a dynamic mathematical model that describes the fate and transport of two selected xenobiotic organic compounds (XOCs) in a simplified representation. of an integrated urban wastewater system. A simulation study, where the xenobiotics bisphenol A and pyrene are used as reference compounds, is carried out. Sorption and specific biological degradation processes are integrated wit

Immunoglobulin g (IgG) anti-tissue transglutaminase antibodies used as markers for IgA-deficient celiac disease patients

The role of immunoglobulin A (IgA) anti-tissue transglutaminase antibodies (IgA-tTG) as predictors of untreated celiac disease (CoD) is well documented, and the presence and levels of these antibodies are most accurately monitored with native or recombinant human antigens. However, IgA-deficient CoD patients are not identified by IgA serology, and conflicting results concerning the diagnostic vali

Phosphate sorption in aluminum- and iron-rich humus soils

Groundwater discharge areas in boreal forest ecosystems can potentially be areas where Fe and Al accumulate in the forest floor and affect the solubility of P. This study was conducted to determine phosphate sorption properties using humus soils containing high native amounts of Al and Fe. Humus soils were collected from two different forested groundwater discharge areas varying in pH and amount a
