The Impact of Information on Consumer Preferences for Different Animal Food Production Methods
The motivation for the present study is to understand food choice in relation to animal food production and to study how preferences are influenced by information. To do this, we carried out a choice experiment. In the analysis, we focus on chickens reared indoors and outdoors and chicken labelled campylobacter-free versus non-labelled chicken. The results suggest that there is a positive willingn
Nitrogen cycling in sediments of the Lagoon of Venice, Italy.
In order to identify the importance of different areas for nitrogen retention in the Lagoon of Venice, Italy, undisturbed sediment cores of different origin were collected in late April 1998. The cores were transferred to the laboratory and incubated for denitrification activity using the method of 'nitrogen isotope pairing'. The sampled sediments were collected in a freshwater stream (Stn A)I an
Late DNA synthesis in heterochromatin.
Precocious gut maturation and immune cell expansion by single dose feeding the lectin phytohaemagglutinin to suckling rats.
The dietary lectin phytohaemagglutinin (PHA) induces gut growth and precocious maturation in suckling rats after mucosal binding. The present study investigated the dose range in which PHA provokes gut maturation and if it coincided with immune activation. Suckling rats, aged 14 d, were orogastrically fed a single increasing dose of PHA: 0 (control), 2, 10, 50 or 250 mug/g body weight (BW) in sali
Large vestibular evoked myogenic potentials in response to bone-conducted sounds in patients with superior canal dehiscence syndrome
Dehiscence of the superior semicircular canal is a 'new' vestibular entity. Among these patients, the vestibular evoked myogenic potentials (VEMP) in response to air-conducted sounds are large. In the present study, VEMP in response to bone-conducted sounds were studied in 5 normal subjects, in 3 patients after ( unilateral) labyrinthectomy and in 4 patients with ( unilateral) superior canal dehis
High glutathione turnover in human cell lines revealed by acivicin inhibition of gamma-glutamyltranspeptidase and the effects of thiol-reactive metals during acivicin inhibition.
Evolution of the Belomorian Belt: NORDSIM U-Pb zircon dating of the Chupa paragneisses, magmatism, and metamorphic stages
The U-Pb systematics of accessory zircons were studied by secondary ion mass spectrometry (NORDSIM ion microprobe). This study revealed two main age groups of terrigenous zircons, 3000 and 2900 Ma, in the metasedimentary rocks of the Chupa nappe of the Belomorian belt. Zircon older than 3200 Ma was not found, which is consistent with the available Sm-Nd model ages. Older terrigenous zircons (3100-
Association of Reported Prostate Cancer Risk Alleles With PSA Levels Among Men Without a Diagnosis of Prostate Cancer
BACKGROUND. Prostate specific antigen (PSA) is widely used for prostate cancer screening but its levels are influenced by many non cancer-related factors. The goal of the study is to estimate the effect of genetic variants on PSA levels. METHODS. We evaluated the association of SNPs that were reported to be associated with prostate cancer risk in recent genome-wide association studies with plasma
High-pressure phase transitions in tetrakis(trimethylsilyl)silane Si[Si(CH3)(3)](4)
The compound tetrakis(trimethylsilyl)silane S-i[Si(CH3,)(3)](4) (TSi) has been studied at room temperature for pressures up to 2 1.5(1) GPa, using X-ray powder diffraction with synchrotron radiation. Three different phases are reported in the investigated pressure range. The c.c.p.-type structure is stable up to a pressure of 0.19(1) GPa (Fm (3) over barm, a = 13.52110)Angstrom, V = 2471.95(1)Angs
Prostaglandin E(2) and BDNF levels in rat hippocampus are negatively correlated with status epilepticus severity: No impact on survival of seizure-generated neurons.
Partial and generalized status epilepticus (pSE and gSE) trigger the same level of progenitor cell proliferation in adult dentate gyrus, but survival of new neurons is poor after gSE. Here, we show markedly elevated levels of prostaglandin E-2 (PGE(2)) and brain-derived neurotrophic factor (BDNF) in rat hippocampal formation at 7 days following pSE but not gSE. Administration of the cyclooxygenase
The Silurian Ireviken Event and vagile benthic faunal turnovers (Polychaeta; Eunicida) on Gotland, Sweden
Genus-level relative frequency changes, based on scolecodont data, show that the polychaete faunas went through dramatic turnovers during the Llandovery-Wenlock Ireviken Event on Gotland. In addition several taxa show range ends (FADs and LADs) and gaps in this interval; at least 20% of the lineages disappeared or became extinct during the event. Datum points 2 and 4 seem to have been particularly
Safe lung preservation for twenty-four hours with Perfadex
The function of six porcine left lung allografts was studied after pulmonary (140 mL/kg) and bronchial (50 mL/kg) artery perfusion with Perfadex (Kabi Pharmacia, Uppsala, Sweden) at room temperature, followed by 24-hour storage of the lungs in an atelectatic state in 6 degrees to 8 degrees C Perfadex, which is a low-potassium-dextran solution. Left lung transplantation was done followed by right p
Unique regulation of SclB - a novel collagen-like surface protein of Streptococcus pyogenes
Slipped-strand mispairing at sites containing so-called coding repeats (CRs) can lead to phase variation of surface proteins in Gram-negative bacteria. This mechanism, believed to contribute to virulence, has so far not been identified in a Gram-positive bacterium. In the genome of the Gram-positive human pathogen Streptococcus pyogenes, we identified pentanucleotide CRs within a putative signal s
Time-Resolved Studies of Light Propagation in Crassula and Phaseolus Leaves
Time-resolved transmittance was used to extract in vivo optical properties of leaves of green plants experimentally. In time-resolved transmittance measurements an ultrashort light pulse is directed onto the surface of the object and the transmitted light is measured with a time resolution in the range of picoseconds. A table-top terawatt laser was used to generate 200 fs light pulses at 790 nm wi
Gas detection by correlation spectroscopy employing a multimode diode laser
A gas sensor based on the gas-correlation technique has been developed using a multimode diode laser (MDL) in a dual-beam detection scheme. Measurement of CO2 mixed with CO as an interfering gas is successfully demonstrated using a 1570 run tunable MDL. Despite overlapping absorption spectra and occasional mode hops, the interfering signals can be effectively excluded by a statistical procedure in
Ordovician limestone in Hälsingland, Sweden
Limestone boulders of Early and Middle Ordovician age occur along the Baltic coast of Sweden from c. 59 degrees N to c. 62.5 degrees N, apparently at a considerable distance from any known source rocks on land. We have investigated a limestone block from Lake Kultebo, at 61 degrees N, not far inland. The conodont elements enclosed in the rock are of Mid-Ordovician age and show that the block could
What's the story? Narration and comprehension in Swedish preschool children with language impairment
This study investigated the possibility of identifying narrative problems at an early age (5-year-old children with language impairment). Furthermore, we explored the relationship between the comprehension of a story and the ability to structure the contents of the same story in a group of preschool children with language impairment. The results showed that the participants did not exhibit age-app
Mechanism of CO oxidation reaction on O-covered Pd(111) surfaces studied with fast x-ray photoelectron spectroscopy: Change of reaction path accompanying phase transition of O domains
We studied the mechanism of CO oxidation on O-precovered Pd(111) surfaces by means of fast x-ray photoelectron spectroscopy (XPS). The oxygen overlayer is compressed upon CO coadsorption from a p(2x2) structure into a (root 3x root 3)R30 degrees structure and then into a p(2x1) structure with increasing CO coverage. These three O phases exhibit distinctly different reactivities. (1) The p(2x2) pha
The Strengths and Difficulties Questionnaire as a screening instrument in a community sample of high school seniors in Sweden
The Strengths and Difficulties Questionnaire (SDQ) has been used among Swedish children since 1996, usually the parent or the teacher version. The self-report version was originally developed for children aged 11-16 years. The aim of this study was to investigate the application of the Swedish self-report version to a representative sample of 1015 senior high school students aged 17-19 years. Girl
