The pK(a) of a C-13-enriched fatty acid probe, tetradecanoic acid, was investigated in a variety of sugar-derived (APG) surfactants by using C-13 NMR to monitor the chemical environment of the probe during titration with base. There was an increase of approximately 2 pK(a) units for the probe within the micellar systems compared to the value of acetic acid in water. Analysis shows that the interfa
Objective: Norepinephrine (NE) is elevated in pregnancies complicated by preeclampsia (PE). Specific uptake of NE by the NE transporter (NET) plays a central role as regulator of NE levels. Expression of NET is reduced in placentas from PE pregnancies. To study adverse fetal effects of reduced NET expression on the placental buffering capacity, the NET was pharmacologically blocked by a specific u
Purpose: Free prostate specific antigen (PSA) in serum consists of heterogeneous molecular subforms. Recently we developed an immunoassay for selective measurement of a subfraction of free PSA called intact PSA, which has been shown to be closely associated with prostate cancer. We assessed the ability of serum intact PSA to discriminate between benign and malignant prostatic disease. Materials an
Popular Abstract in Swedish Cafeterian i Malmö Musikhögskola förvandlas två gånger om året till de passionerades mötesplats: När terminens ”Gambiastudenter” återvänder efter sina tre veckors fältarbete och skola med palmer som klassrumsväggar, möts de av veteranerna, de som redan varit där och som förstår att tolka entusiasmen. Det handlar inte om den vitalitet som alstrats av solen, färgerna och The present study seeks to examine attitudes to teaching and learning among jalis in the Gambia. Although this is the main focus, the horizon of which the study is carried out, analysed and discussed, is the development of music teacher education in Sweden during the last three decades, and of which I have been a participant. The intention of the study is to expand current views on music teaching
The risk of seizure recurrence within the first year of life was evaluated in infants with neonatal seizures diagnosed with a combination of clinical signs, amplitude-integrated electroencephalogram (EEG) monitoring, and standard EEG. Fifty eight of 283 (4.5%) neonates in tertiary level neonatal intensive care had seizures. The mortality in the infants with neonatal seizures was 36.2%. In 31 survi
A number of screening procedures are offered by midwives during pregnancy and the number is increasing rapidly. The measurement of nuchal translucency is a fairly new ultrasound method for antenatal screening, primarily for Down syndrome. The results give a better risk calculation than maternal age alone and can mean a decrease in the number of invasive procedures needed to identify this syndrome
The possibilities for implementing a rainwater collection system in Ringdansen, a residential area in Norrkoping, Sweden, have been explored by analysing four scenarios for using rainwater in a dual water supply system to supplement drinking water. A computer model has been generated to quantify the water saving potential of the rainwater collection scheme. The performance of the rainwater system
Signaling mechanisms for stretch-dependent growth and differentiation of vascular smooth muscle were investigated in mechanically loaded rat portal veins in organ culture. Stretch-dependent protein synthesis was found to depend on endogenous release of angiotensin II. Autoradiography after [35S]methionine incorporation revealed stretch-dependent synthesis of several proteins, of which SM22 and act
BACKGROUND: RBCs of the Hy- phenotype have, in the past, been typed as Gy(a+(w)), Hy-, Jo(a-), and RBCs with the Jo(a-) phenotype type Gy(a+), Hy-(w), and Jo(a-). Anti-Hy and anti-Jo(a) are difficult to identify mainly because appropriate reagent R6Cs are poorly characterized. Historically, anti-Jo(a) has not reacted with RBCs with either phenotype. This report describes a case of an anti-Jo(a) th
The influence of the auxotrophic deficiencies of the host strain and expression vector selection on the production of a heterologous protein was investigated. Heterologous xylanase production by two prototrophic S. cerevisiae transformants, containing either a plasmid-based, YEp-type expression system or an integrative, YIp-type expression system, were compared with production by an auxotrophic tr
A technique to estimate fungal growth rates in field samples was tested in soil. The technique is based on the addition of C-14-acetate to a soil slurry and the subsequent uptake and incorporation of the labelled acetate into the fungus specific substance ergosterol by the fungi. The addition of fungal inhibitors decreased acetate incorporation rates, while bacterial inhibitors did not. Fungus-fre
Introduction: Complex production systems as, for instance, those used in health care, in off shore industry, in nuclear power industry or in aviation suffer now and then from severe system breakdowns. Lessons learnt from these often lead to changes in the "system". A more rational approach would be to identify these "system weaknesses" before accidents happen. A new proactive method, DEB analysis,
The molecular mechanism of substrate analogue interaction with Escherichia coli dUTPase was investigated, using the non-hydrolyzable 2'-deoxyuridine 5'-(α,β-imido)triphosphate (α,β-imido-dUTP). Binding of this analogue induces a difference in the far UV circular dichroism (CD) spectrum arguing for a significant change in protein conformation. The spectral shift is strictly Mg2+-dependent, does not
It is generally accepted that mating in flour beetles of the genus Tribolium is mediated by a male-produced aggregation pheromone. The pheromone production site in T. castaneum is believed to be glands on the ventral side of the femur. Behavioural experiments with the confused flour beetle T. confusum were conducted using extracts of beetles and different body parts as well as live beetles to inve
