Introduction Ihe association of physical inactivity with mortality, cardiovascular disease and cancer is extensively studied in adults. Clustering of cardiovascular risk factors and objectively measured physical activity in children and youth has not been convincingly established. The sustainability of objectively measured physical activity into adulihood is not satisfactorily studied. Acceleromet
The MAX IV storage rings, currently under construction in Lund, Sweden, will use third harmonic cavities operated passively to lengthen the bunches and alleviate collective instabilities. These cavities are an essential ingredient in the MAX IV design concept and are required for achieving the final design goals in terms of stored current, beam emittance, and beam lifetime-such performance challen
In recent years, smog has become one of greatest challenges in China and many other countries. However, there are limited attentions of measuring public environment awareness of air pollution and the relations between public environmental awareness and smog prevention in a Chinese context. This study was designed to investigate the facts of public environmental awareness in a typical city of China
Receding glaciers are among the most obvious changes caused by global warming, and glacial meltwater entering lakes generally forms plumes of particles. By taking vertical samples along a horizontal gradient from such a particle source, we found that photosynthetically active radiation (PAR) and ultraviolet radiation (UVR) attenuated 20-25% faster close to the inflow of suspended particles compare
Effects of peptide hydrophobicity on lipid membrane binding, incorporation, and defect formation was investigated for variants of the complement-derived antimicrobial peptide CNY21 (CNYITELRRQHARASHLGLAR), in anionic 1-palmitoyl-2-oleoylphosphatidylethanolamine (POPE)/1-palmitoyl-2-oleoylphosphatidylglycerol (POPG) and zwitterionic 1-palmitoyl-2-oleoylphosphatidylcholine (POPC) membranes. Using a
An experimental study of methane + air flames doped with ammonia (4370 ppm of the fuel) has been performed. The goal of this work was to analyze formation of NOx from fuel-N under well-controlled conditions. The Heat Flux method was used for stabilization of non-stretched adiabatic flames on a perforated plate burner at atmospheric pressure. Laser-saturated fluorescence (LSF) and probe sampling we
This paper presents a method designed to identify underlying causes leading to industrial accidents. The method developed intends to facilitate the learning process from accidents by identifying possible causes related to the accidents that were not directly stated in an accident report, but that can be deduced following the description of the event, in particular with regard to the quality of the
Umbilical cord blood acid-base status at birth gives an objective evaluation of the fetal exposure and response to hypoxia during labor. The objective of this thesis was to elucidate methodological issues associated with interpretation of cord blood gases. DELAYED CORD BLOOD SAMPLING (Paper I): arterial and venous pH and bicarbonate decreased, and pCO2, base deficit (BD), and lactate increased sig
Attaining high peak bone mass (PBM), the highest bone mass value in life which is reached in young adulthood, is important as it reduces the risk of having low bone mass in old age69, 80. Low bone mass is associated with high fracture risk3, 60. Osteoporosis is the result of bone loss, a physiological process related to aging and/or low PBM. It would therefore be of great value to identify childre
Popular Abstract in Swedish De flesta större operationer på hjärtat idag kräver att hjärtat under en del av operationen står stilla utan att blod cirkulerar igenom det. För att kunna bibehålla ett blodflöde av syresatt blod genom kroppen kopplas en hjärt-lungmaskin till patienten. Blodet förs via slangar från höger förmak först ner till ett uppsamlingskärl, varifrån blodet pumpas vidare genom en oThe use of cardiotomy suction during open heart surgery with cardiopulmonary bypass (CPB) has a long tradition and often regarded as mandatory. Recently, studies have described potentially negative effects of cardiotomy suction with activation of the complement system, enhanced inflammatory response, hemolysis and coagulopathy. Emboli of various matters has also been studied. Whether they affect t
Numerous fossil meteorites and high concentrations of sediment-dispersed extraterrestrial chromite (EC) grains with ordinary chondritic composition have previously been documented from 467 +/- 1.6 Ma Middle Ordovician (Darriwilian) strata. These finds probably reflect a temporarily enhanced influx of L-chondritic matter, following the disruption of the L-chondrite parent body in the asteroid belt
Weathering of soil minerals is important for the recovery from acidification and for the sustainability of forestry. However, there is still substantial uncertainty about its absolute rate. This study presents a harmonized comparison of field weathering rates estimated with the mechanistic model PROFILE and the depletion method for 16 intensively sampled soil profiles across Sweden representing di
By applying a novel approach to evaluate photofragmentation laser-induced fluorescence (PFLIF) imaging, experimental quantitative information on the temporal in-cylinder distribution of hydrogen peroxide (H2O2) in a homogeneous charge compression ignition (HCCI) engine was extracted. The results from PFLIF were then compared to those obtained from chemical kinetics simulations using computational
The Child and Adolescent Twin Study in Sweden (CATSS) is an ongoing longitudinal twin study targeting all twins born in Sweden since July 1, 1992. Since 2004, parents of twins are interviewed regarding the children's somatic and mental health and social environment in connection with their 9th or 12th birthdays (CATSS-9/12). By January 2010, 8,610 parental interviews concerning 17,220 twins had be
As with mosquitoes, female tabanid flies search for mammalian hosts by visual and olfactory cues, because they require a blood meal before being able to produce and lay eggs. Polarotactic tabanid flies find striped or spotted patterns with intensity and/or polarisation modulation visually less attractive than homogeneous white, brown or black targets. Thus, this reduced optical attractiveness to t
In the present study we combined interferon (IFN) and hydroxyurea (HU) treatment, intensive chemotherapy and autologous stem cell transplantation (SCT) in newly diagnosed chronic myelogenous leukemia patients aged below 56 years, not eligible for allogeneic SCT. Patients who had an HLA-identical sibling donor and no contraindication went for an allogeneic SCT (related donor, RD). After diagnosis,
Chromosome abnormalities have been reported in more than 46,000 benign and malignant neoplastic disorders, leading to the identification of numerous recurrent abnormalities. A substantial number of recurrent balanced aberrations (RBAs), in particular, reciprocal translocations, occur with remarkable specificity in association with clinical and tumor characteristics. This information has become inc
Functional recovery following intrastriatal transplantation of fetal dopaminergic neurons in animal models of Parkinson's disease is, at least in part, dependent on the number of surviving dopaminergic neurons and the degree of graft-derived dopaminergic reinnervation of the host striatum. In the present study, we analyzed whether continuous exposure of glial cell line-derived neurotrophic factor
The carotenoid species lutein, violaxanthin, and zeaxanthin are crucial in the xanthophyll-dependent nonphotochemical quenching occurring in photosynthetic systems of higher plants, since they are involved in dissipation of excess energy and thus protect the photosynthetic machinery from irreversible inhibition. Nonetheless, important properties of the xanthophyll cycle carotenoids, such as the en
OBJECTIVE: To evaluate the pathogenesis of metaplastic processes within the esophagus using a human model in which the exact duration of reflux was known. SUMMARY BACKGROUND DATA: The pathogenesis of Barrett's esophagus (BE) is incompletely understood. Patients undergoing esophagectomy and gastric tube reconstruction represent a good model for studying the pathophysiology of columnar cell metaplas
