Background & Aims: Human milk is believed to contain biological factors involved in the regulation of newborn growth, including brain development. Recently, it has also been shown to contain the calcium-binding S100B protein, regarded as a neurotrophic factor. The present study investigates the concentrations of this protein in colostrum, human milk at different levels of maturation and in mil
Increased nitrogen leaching from forest soils is a potential environmental problem in areas with high nitrogen deposition. In Sweden nitrogen is strongly retained in the forests, and high nitrogen leaching is not common from growing forests. However, soil water measurements on clearcuts along a deposition gradient in Sweden showed a positive correlation between increased concentration of inorganic
Glutathione peroxidase activity (GSHPx), total and soluble selenium in two muscles from five species were compared (chicken, duck, turkey, ostrich and lamb). The highest GSHPx activity, found in duck muscles (4.8 U/g; 3.0 U/g), was significantly higher than that in lamb (1.8 U/g; 1.4 U/g), turkey (1.2 U/g; 0.6 U/g), chicken (1.0 U/g; 0.7 U/g), and ostrich muscles (0.9 U/g; 0.8 U/g). GSHPx activiti
A large gravel pit 30 km north of the Pomeranian ice margin has been investigated. Besides gravel, sand, fines and diamicton, several deposits of organic material are present, some of them showing a typical Eemian Pollen- and macroflora. Previous interpretations assume that the sediments below the Eemian peat belong to the Saalian, and those above the peat to the Weichselian. Sorted sediments in t
Resuscitation with pure oxygen at birth after fetal asphyxia may aggravate brain damage by inducing pro-inflammation. The toll-like receptors (TLRs) may serve a pro-inflammatory role in hyperoxemia during ischemia-reperfusion. Sixteen near-term fetal sheep (132-136 d) were subjected to 10 min of cord occlusion, delivery and mechanical ventilation with 100% O-2 (n = 8), or 21% O-2 (n = 8) for 30 mi
Background: Limited information exists on the framework and content of postgraduate education in internal medicine in Europe. This report describes the results of a survey of postgraduate training in internal medicine in the European countries. Methods: Two online questionnaire-based surveys were carried out by the European Board of Internal Medicine, one on the practice of internists and the othe
As the identification process is based on the unique patterns of the users, biometrics technologies are expected to provide highly secure authentication systems. The existing systems using fingerprints or retina patterns are, however, very vulnerable. One’s fingerprints are accessible as soon as the person touches a surface, while a high resolution camera easily captures the retina pattern. Thus,
Background: In recent years an increase of the incidence of nosocomial outbreaks caused by noroviruses has been observed throughout Sweden, with high peaks noted in the winter seasons 2002/2003 and 2004/2005, respectively. Objectives: To phylogenetically characterize norovirus strains causing nosocomial outbreaks from 1997 to 2005 and estimate the impact of norovirus-like disease on the Swedish he

BACKGROUND: Mean left atrioventricular plane displacement is strongly related to prognosis in patients with heart failure. We aimed to examine its value for prognostication and risk stratification in patients hospitalised for acute myocardial infarction. METHODS AND RESULTS: Left atrioventricular plane displacement was assessed by echocardiography in 271 consecutive patients with acute myocardial
Background: Spontaneous bacterial peritonitis (SBP), which has been reported to be present in 10-30% of patients with cirrhotic ascites, may easily be overlooked. An important aim of our study was to determine whether there are any clinical signs which, in clinical practice, may predict or exclude SBP. Methods: We studied 133 patients with cirrhotic ascites from medical units at nine Swedish unive
BACKGROUND: The incidence of acute cardiovascular and cerebrovascular events in patients treated for complicated or uncomplicated peptic ulcer disease (PUD) has not been ascertained completely. METHOD: All patients with in-hospital treatment due to PUD between 1987 and 2007, who did not have any past history of acute or chronic cardiovascular or cerebrovascular disease, were identified through the
Studien ämnade att undersöka hur väl personlighet respektive könsidentifiering, var för sig respektive tillsammans, kan predicera ideologisk orientering. För att undersöka detta användes personlighetstestet HEXACO och könsidentifieringstestet BSRI. Syftet med uppsatsen var att öka väljarförståelsen. Studien utgick ifrån ett bekvämlighetsurval (N=272), med 171 kvinnor och 101 män. Samtliga var svenThis aim of this thesis was to examine how well personality and gender-identification, by themselves and combined, were able to predict ideological orientation. This through the personality test HEXACO and gender-identification test BSRI. The purpose of the study was to help improve the understanding of Swedish voters. The sample was a convenience sample (N=272), with 171 women and 101 men, all Sw
The demand for high data rates in a wireless communication system has experienced a remarkable growth over the last years. This demand is continually increasing with the growing number of wirelessly connected devices. Thus, there is a continuing hunt for increasing the data transmission rate in wireless communication systems. To increase the data rate, the modern wireless communication system cann
Interneurons have been found to be important for normal cognitive function. Impairments to their growth or signaling have been indicated to be involved in the development of schizophrenia, autism and epilepsy. Defective functioning in GABA:ergic interneurons has been linked to undesired desynchronous firing in neural signals as a consequence of these interneurons firing too infrequently or not at
Som vi har märkt på grund av de senaste årens höga elpriser är en jämn elproduktion från grön energi väldigt viktig. Solkraft där man lagrar energi i smält salt kan användas för att sprida ut eltillverkningen på alla dygnets timmar. Utvinningen av saltets energi är då högst betydelsefull och denna har undersökts genom effektiva och simpla flödessimuleringar i detta arbete. Dessa flödessimuleringaTo be able to meet the global energy demands, a steady supply of green energy is required, even during sun- or windless hours. Concentrated solar power is a useful alternative, which can produce and store green energy by heating a heat transfer fluid (HTF) and extracting its energy via a heat exchanger. One such category of HTF is molten salts, and to understand and be able to model the behaviour
The present Comite´ Europe´en de Normalisation (CEN) and International Organization for Standardization (ISO) standards for safety, protective and occupational footwear EN ISO 20344–20347 classify footwear as cold protective by a pass/fail test where the limits are set for an allowed 10 °C temperature drop inside the footwear during 30 min at a temperature gradient of ~40 °C. It is questionable if
Laminar burning velocities of syngas/air premixed flames, varying with H-2/CO ratio (from 5/95 to 75/25) and N-2 or CO2 dilution rate (from 0% to 60%), were accurately measured using a Teflon coated Heat Flux burner and OH-PLIF based Bunsen flame method. Experiments were carried out at atmospheric pressure and room temperature, with fuel/air equivalence ratios ranging from fuel-lean to fuel-rich.
Virtual Reality and advanced, interactive simulators illustrate the potentials of modern technology for improving the ecological validity of learning experiments. Yet much more preliminary work is needed to appreciate how these growingly complex means can be utilized to promote high-order emotional and motivational constructs of the user, such as self-efficacy. Drawing from the frameworks of serio
