Human G protein-coupled receptor GPR-9-6/CC chemokine receptor 9 is selectively expressed on intestinal homing T lymphocytes, mucosal lymphocytes, and thymocytes and is required for thymus-expressed chemokine-mediated chemotaxis

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,

An algorithm for real-time dosimetry in intensity-modulated radiation therapy using the radioluminescence signal from Al2O3 : C

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

Advancing Bioenergy in Europe: Exploring bioenergy systems and socio-political issues

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,

No indications of increased quiet sleep in infants receiving care based on the Newborn Individualized Developmental Care and Assessment Program (NIDCAP)

It has been proposed that the developmentally supportive care of very-low-birthweight (VLBW) infants provided by the Newborn Individualized Developmental Care and Assessment Program (NIDCAP) can improve the infants' opportunities for rest and sleep. The aim of the present study was to determine whether quiet sleep (QS) in VLBW infants is affected by NIDCAP care. Twenty-two infants with a gestation

Direct electron transfer kinetics in horseradish peroxidase electrocatalysis

The study of direct electron transfer between enzymes and electrodes is frequently hampered by the small fraction of adsorbed proteins that remains electrochemically active. Here, we outline a strategy to overcome this limitation, which is based on a hierarchical analysis of steady-state electrocatalytic currents and the adoption of the "binary activity" hypothesis. The procedure is illustrated by

Mikrobiell påväxt på fasader

I huvudsak har putsade fasader undersökts. Tre nybyggda hus i Stockholmsområdet, ett ca. 20 år gammalt provhus i Dalby samt ett objekt i Ärvinge har undersökts med avseende på missfärgningar förorsakade av bland annat mögelsvamp men även av lavor, mossor och alger. Denna inledande undersökning behandlar, i alla väsentliga delar, vad för sorts påväxt som bidrar till missfärgningar av fasader. I skr

This study investigates the syntax, semantics and information structure of it-cleft constructions in German and Swedish. The syntactic analysis is presented within a standard framework of generative theory. In defining genuine cleft constructions, both the syntactic and the semantic structures of clefts are taken into consideration. Here, it proves essential to distinguish between different kinds

Cause of late death after cardiac surgery in the very elderly: a single institution experience.

OBJECTIVES: The referrals of elderly for cardiac surgery are increasing. The aim of this retrospective study is to review the long-term survival and to identify causes of late death in elderly after cardiac surgery. DESIGN: Between 1990 and 1993, 130 octogenarians underwent cardiac surgery in our department. A majority (88%) had elective surgery. One hundred and nine patients (84%) were in New Yor

Potent P2Y6 receptor mediated contractions in human cerebral arteries

BACKGROUND: Extracellular nucleotides play an important role in the regulation of vascular tone and may be involved in cerebral vasospasm after subarachnoidal haemorrhage. This study was designed to characterise the contractile P2 receptors in endothelium-denuded human cerebral and omental arteries. The isometric tension of isolated vessel segments was recorded in vitro. P2 receptor mRNA expressio

Validity and reliability of the Behavioural Observational Pain Scale for postoperative pain measurement in children 1-7 years of age

Objective: Pain measurement is a necessity in pain treatment but can be difficult in young children. The aim of this study was to evaluate the validity and reliability of the Behavioural Observational Pain Scale (BOPS) as a postoperative pain measurement scale for children aged 1-7 yrs. The scale assesses three elements of pain behaviors: facial expression, verbalization, and body position. Design

Micro-immuno supported liquid membrane assay (mu-ISLMA)

A chemiluminescent (CL) based micro-immuno supported liquid membrane assay (mu-ISLMA) has been developed that enables clean up, enrichment and detection of simazine in a single miniaturised cartridge system. The mu-ISLM cartridge contains a supported liquid membrane (SLM) sandwiched between a donor and an acceptor plate (channel volumes 1.65 mu L), the latter being covered by a thin layer of gold
