Age- and weight-matched groups of mice were enclosed in airtight chambers and exposed to clean, filtered air for 1 month. At the end of the exposure period, body, liver and spleen weights and plasma butyrylcholinesterase (BuChE) activity were measured. More than twice as many significant differences in these parameters occurred compared with the expected results if only random differences existed

Pristane-induced arthritis (PIA) in rats, a model for rheumatoid arthritis (RA), is a T cell-dependent disease. However, pristane itself is a lipid and unable to form a stable complex with a MHC class II molecule. Therefore, the specificity and function of the T cells in PIA are as unclear as in rheumatoid arthritis. In this study, we show that activated CD4+ alphabetaT cells, which target periphe

The aim of the present study was to examine the influence of pregnancy on deterioration of retinopathy in patients with Type 1 diabetes mellitus. Sixty-five pregnant Type 1 diabetic women attending the University Hospital in Lund were studied retrospectively. The degree of retinopathy, and levels of HbA1c and blood pressure 12 months before, during, and 6 months after pregnancy were compared of th

Objective To explore fetal ductus venosus (DV) flow velocity changes relative to umbilical artery (UA) blood flow and brain-sparing flow (BSF) during uterine contractions. Methods Forty-five term fetuses suspected of having growth restriction were exposed to an oxytocin challenge test (OCT) with simultaneous Doppler velocimetry in the UA, middle cerebral artery (MCA) and DV. Basal BSF was defined

Objective: To compare the three year safety and efficacy of cyclosporin and parenteral gold in the treatment of early, active, severe rheumatoid arthritis (RA), and to study the reversibility of cyclosporin associated renal dysfunction in patients who discontinued cyclosporin treatment. Methods: The patients continued to receive cyclosporin or parenteral gold in an 18 month open extension to an 18

An association between severe infant bronchiolitis due to respiratory syncytial virus (RSV) and subsequent wheezing is well documented. High levels of urinary eosinophil protein X (U-EPX) have been related to active disease in asthmatic children. The aim of this study was to analyse whether RSV bronchiolitis leads to an increase in U-EPX levels and whether wheezing is more common in children with

The available evidence suggests that both genes and environment play a crucial role in the development of juvenile-onset myopia. When the human visual system is examined from an evolutionary perspective, it becomes apparent that humans, living in the original environmental niche for which our species is genetically adapted (as hunter-gatherers), are either slightly hypermetropic or emmetropic and

Rapporten behandlar styr- och reglertekniska funktioners inverkan på energiförbrukningen i byggnader. Den omfattar presentation av undersökta objekt med beskrivning av de olika installationssystemen, redogörelse för redan gjorda driftserfarenheter samt beskrivning av energibesparande modifieringar av driftsätt.

eta(c)(2980) production in gammagamma interactions has been detected via its decays into K(s)(0)K(-/+)pi(-/+), K+K-K+K- and K(+)K(-)pi(+)pi(-) in the data taken with the DELPHI detector at LEP1 and LEP2 energies. The two-photon radiative width averaged over all observed decay channels is Gammagammagamma=13.9+/-2.0(stat.)+/-1.4(syst.)+/-2.7 (BR) keV. No direct decay channel eta(c)-->pi(+)pi(-)pi(+)

Chlorophyll, heme, phytochrome and siroheme biosynthesis in higher plants is regulated by the supply of their precursor 5-aminolevulinate (ALA), which is derived from glutamate. Glutamate conversion to ALA occurs only in the plastid and requires chloroplast coded tRNA(Glu) and nuclear coded glutamyl-tRNA synthetase, glutamyl-tRNA reductase and glutamate 1-semialdehyde aminotransferase. The chromos

Omvärdering av den kritikerutskällda Starship Troopers (1998)

In this paper we derive an integral equation for the evolution of unintegrated (longitudinally) polarized quark and gluon parton distributions. The conventional Catani-Ciafaloni-Fiorani-Marchesini (CCFM) framework is modified at small x in order to incorporate the QCD expectations concerning the double ln(2)(1/x) resummation at low x for the integrated distributions. Complete Altarelli-Parisi spli

Lifetime measurements have been made for the radiation emitted in the ground term transitions of the nominal form 5s(2)5p(6)5d(x)6s-5s(2)5p(6)5d(x)6p in Ta II (x = 3), W II (x = 4), and Re II (x = 5). Supporting theoretical calculations have also been performed to characterize configuration interaction and to estimate the degree of decay branching of the upper levels. The lifetime measurements hav

Endogenous peptide antibiotics are known as evolutionarily old components of innate immunity. Due to interaction with cell membrane these peptides cause permeabilization of the membrane and lysis of invading microbes. However, some studies proved that antimicrobial peptides are universal multifunctional molecules and their functions extend far beyond simple antibiotics. In this review we present a

I denna rapport redovisas resultaten från mätningar utförda i ett experimenthus i Halmstad som är grundlagt med den så kallade installationsgrunden enligt EG-2000 konceptet. Insamlade mätdata används för beräkningar av energianvändningen och energibalansen. Energianvändningen i experimenthuset jämförs med energianvändningen i ett liknande hus grundlagt med platta på mark.

We present a functional response model that primarily evaluates effects of satiation in piscivore prey-size selection. The model also includes other passive processes, such as prey-size-dependent encounter rate and prey-size-dependent capture success, where capture success decreases and encounter rate increases with prey size. The model generates a wide variety of outcomes, where small, intermedia
