A flow injection analysis (FIA) system for specific determination of L-glutamate in food samples based on a bi-enzymatic amplification system has been developed. The content of L-glutamate in the sample was amplified by cycling between L-glutamate dehydrogenase (GIDH) and a novel enzyme, D-phenylglycine aminotransferase (D-PhgAT). In this system, GIDH converts L-glutamate to 2-oxoglutarate with co

Seven patients with type 1 diabetes mellitus were restored to near normoglycaemia by treatment with continuous subcutaneous insulin infusion pumps (CSII). The patients were examined with ophthalmoscopy, fundus photography and fluorescein angiography before and one year after the start of CSII treatment. In addition, ophthalmoscopy was performed after 6 months of treatment. All 14 eyes were normal

Bi-isonicotinic acid (2,2'-bipyridine-4,4'-dicarboxylic acid) is an important ligand in the chemistry of organometallic devices. Here, the adsorption of a monolayer of the molecule on in situ-grown anatase TiO2 nanoparticles has been investigated by means of X-ray photoemission spectroscopy and X-ray absorption spectroscopy. The bonding geometry is determined to be 2M-bidentate. Furthermore, reson

The purpose of this study was to determine the reliability of an isokinetic test for ankle dorsiflexion fatigue on a Biodex dynamometer Young (21 to 32 years), recreationally active men (n = 10) and women (n = 10) performed 50 concentric (60degrees . s(-1)) dorsiflexion contractions, on two different occasions. Total work (TW), losses in work (work fatigue; WF), as well as relative losses in peak

Objective: To review and sum up the published literature on gynecological Doppler ultrasound examination. Methods: Publications on gynecological Doppler ultrasound examination already known by the author, publications found in the bibliographic database Medline, and publications found in the reference lists of available studies were read, and relevant information was extracted and summarized. Resu

International standardization and coordination of the nomenclature of variants of hepatitis C virus (HCV) is increasingly needed as more is discovered about the scale of HCV-related liver disease and important biological and antigenic differences that exist between variants. A group of scientists expert in the field of HCV genetic variability, and those involved in development of HCV sequence data

Dynamic changes in absolute residual PME activity in potato tubers undergoing blanching were analysed with regard to the temperature distribution in the tissue after the treatment. The finite-element technique was used to predict the temperature distribution within the tissue during blanching. The temperature-related behaviour of the enzyme indicated that blanching between 60 and 70 degreesC induc

We examined the occurrence of blowfly larvae Trypocalliphora brauneri in Swedish willow warbler Phylloscopus trochilus nestlings at three nearby breeding sites in Central Sweden. The occurrence of parasites was examined in nestlings by visual inspection during ringing. Larvae were encapsulated in the wings, head, neck, or the sides of the body of the nestlings and caused large swellings. Some of t

Popular Abstract in Swedish Detta är en prospektiv longitudinell multicenterstudie som har haft som mål att utvärdera livskvaliteten (HRQL) hos patienter med cancer i huvudhalsregionen, vid diagnos, efter ett och fem år i relateration till tumörlokal, stadium, subsite, behand-ling, kön och ålder. Den första delen av studien, som varade i ett år, bestod av 357 patienter (medelålder 63 år; 72% män)The aim of this prospective longitudinal multicenter study was to evaluate the health-related quality of life (HRQL) in patients with head and neck cancer at diagnosis, after one and five years in relation to tumour location, stage, sub site, treatment modality, gender and age. The first part of the study, lasting for one year, consisted of 357 patients (mean age 63 years; 72% males) that were in

Tone reservation peak-to-average ( PAR) ratio reduction is an established area when it comes to bringing down signal peaks inmulticarrier (DMT or OFDM) systems. When designing such a system, some questions often arise about PAR reduction. Is it worth the effort? How much can it give? How much does it give depending on the parameter choices? With this paper, we attempt to answer these questions wit

TECK (thymus-expressed chemokine), a recently described CC chemokine expressed in thymus and small intestine, was found to mediate chemotaxis of human G protein-coupled receptor GPR-9-6/L1.2 transfectants. This activity was blocked by anti-GPR-9-6 monoclonal antibody (mAb) 3C3. GPR-9-6 is expressed on a subset of memory alpha4beta7(high) intestinal trafficking CD4 and CD8 lymphocytes. In addition,

Plasma homocysteine concentrations in a group of 80-year-old persons were related to symptoms and signs. Plasma homocysteine concentrations higher than 15 mumol/l were associated with lower total life satisfaction (P

Although the radioluminescence (RL) signal from optical fibre Al2O3:C dosemeters used in medical applications is essentially proportional to dose rate, the crystals used so far are imperfect in the sense that their RL sensitivity changes with accumulated dose. A computational algorithm has been developed that corrects for these sensitivity changes. We further report on a new system that effectivel

Popular Abstract in Swedish Detta är en avhandling om bioenergi (eller biomassa som används för produktion av värme, el eller som drivmedel), om dess betydande potential och viktiga alternativ. Biomassa kan ses som solenergi som fångats genom fotosyntes och lagrats i växande biomassa. Men bra förutsättningar kan bioenergi starkt bidra till minskad klimatpåverkan, ökad förbättrad försörjningstrygghThis thesis concentrates on bioenergy (or biomass utilised for heat, electricity and fuels for transport) as a renewable energy with significant potentials and options. Biomass can be considered as 'stored' solar energy because the process of photosynthesis 'captures' energy from the sun in growing plants. Bioenergy systems under the 'right' conditions can greatly contribute to climate mitigation,
