The aim of the study was to assess the short-term cardiorespiratory effects of a standard red cell transfusion in very low birth weight (<1500 g) infants undergoing intensive care. A total of 37 infants (birth weight 920+/-230 g, gestational age 27.8+/-2.1 weeks, age at study 6.1+/-3.9 days) with indwelling arterial lines were studied when 10 ml/kg of packed donor red cells were transfused based o

This is an exploratory study of the use of wh-questions in Swedish children with typical and impaired language development. Swedish is a verb-second (V2) language where inverted word order is not unique to wh-questions, but occurs in all utterances that begin with a constituent other than the subject. The purpose was to investigate types and frequency patterns in the use of wh-questions, wh-word a

Pathophysiological activity and various kinds of traumatic insults are known to have deleterious long-term effects on neuronal Cl- regulation, which can lead to a suppression of fast postsynaptic GABAergic responses. Brain-derived neurotrophic factor (BDNF) increases neuronal excitability through a conjunction of mechanisms that include regulation of the efficacy of GABAergic transmission. Here, w

In this paper, we present and discuss results from an investigation of verb placement in modern Faroese in which we collected data from speakers from a number of different dialect areas in the Faroe Islands. Altogether we interviewed 54 informants (age 15 – 67, 29 women and 25 men). Therefore, our study not only investigates the geographical variation claimed to be present in Faroese with respect

Near-infrared (NIR) spectroscopy is a useful technique for quantitative measurements of intact tablets, but it suffers from limitations due to the fact that changes in the physical properties of a sample strongly affect the recorded spectrum. In this work, time-resolved transmission NIR spectroscopy was utilized to conduct quantitative measurements of intact tablets. The technique enables separati

Transcranial magnetic stimulation (TMS) with weak (micro Tesla) complex waveform fields have been claimed to evoke the sensed presence of a sentient being in up to 80% in the general population. These findings have had a questionable neurophysiological foundation as the fields are approximately six orders of magnitude weaker than ordinary TMS fields. Also, no independent replication has been repor

Climatic warming leads to the expansion of deciduous shrubs and trees in the Arctic. This leads to higher leaf litter inputs, which together with warming may alter the rate of carbon and nutrient cycling in the arctic ecosystems. We assessed effects of factorial warming and additional litter on the soil ecosystem of a subarctic heath in a 7-year-long field experiment. Fine root biomass, dissolved

Accurate assessment of human intake of mutagenic/carcinogenic heterocyclic ainines (HAs) is necessary for epidemiological studies and future risk assessment. Using questionnaires, the frequency of consumption of specific dishes can be obtained at an individual level and linked to analyzed concentrations of different compounds in corresponding dishes. Some typical Swedish cooked meat dishes, hambur

Immune responses against oxidized forms of LDL play a critical role in activation and regulation of the inflammatory process that characterizes all stages of atherosclerosis. In humans oxidized LDL is targeted by both IgM and IgG autoantibodies. Immunization of hypercholesterolemic animals with oxidized LDL has been shown to inhibit atherosclerosis demonstrating that at least some of these immune

In this Letter we consider the evolution of a planetary system around a star inside a wide binary. We simulate numerically the evolution of the planetary orbits for both coplanar and highly inclined systems. We find that the Kozai mechanism operates in the latter case. This produces a highly eccentric outer planet the orbit of which crosses those of some of the inner planets. Strong planet-planet

The visual content of out-of-body experiences (OBEs) has received little attention but a number of theories of OBEs include implicit predictions regarding the determinants of this phenomenological feature. Hypnagogic imagery and unusual sleep experiences, weak synaesthesia and preference for employing object and spatial visual imagic cognitive styles were psychometrically measured along with the i

Background: Legislation was passed in Sweden to stimulate the development of different housing solutions for persons suffering from severe mental illness. Among these solutions are small congregate residences built in the community to provide suitable housing and support for those not able or willing to live independently. Aims: The general aim of the present study was to compare the psychosocial

It has been argued that waterfowl and fish may threaten growth of submerged macrophytes, especially in spring during the early growth phase when plant biomass is low. A small reduction of biomass at that time might delay growth or decrease subsequent productivity. We investigated the impact of waterfowl and large fish on the spring growth of fennel pondweed (Potamogeton pectinatus L.) by employing

Antibody-based microarray is a novel technology with great promise within high-throughput proteomics. The tremendous complexity of all proteomes will, however, pose major technological challenges, especially when targeting low-abundant analytes that remains to be resolved. In this paper, we have shown that antibody microarrays readily could be used for screening of low-abundant low molecular weigh

Lumican and fibromodulin compete for collagen type I binding in vitro and fibromodulin-deficient mice have four-fold more lumican in tendons. These observations indicate that homologous sequences in lumican and fibromodulin bind to collagen type I. Here, we demonstrate that lumican binding to collagen type I is mediated mainly by Asp-213 in LRR 7. The mutation D213N in lumican impairs interaction

Individuals are often restricted to indirect cues when assessing the mate value of a potential partner. Females of some species have been shown to copy each other’s choice; in other words, the probability of a female choosing a particular male increases if he has already been chosen by other females. Recently it has been suggested that mate-choice copying could be an important aspect of human mate

Phospholipase C-gamma (PLC-gamma) isoforms are thought to be activated by both tyrosine phosphorylation and phosphatidylinositol 3,4,5 trisphosphate (PtdIns 3,4,5 P(3)), the product of phosphatidylinositol 3-kinase (PtdIns 3-kinase). In this study, we show that stimulation of mouse macrophages with either zymosan beads or bacteria (Prevotella intermedia) induced tyrosine phosphorylation of PLC-gam

The optimal definition of the size, shape and location of gross tumour volume is one of the most important steps in the planning of radiation therapy, and necessitates a proper understanding of the procedure from both the oncologic radiologist and the radiation oncologist. This overview reports on the different terms and concepts that have been recommended in the ICRU Reports for this purpose; the

Here, the problem of the classical chaos effect on dissipation in nuclear many-body systems is addressed. To investigate this problem, the energy response on parametric driving of external confinement of the simplest interacting many-body system is studied: two identical like-charged particles moving on the plane in the field of a deformed harmonic oscillator, which shows a rich structure of the c
