Background: The incidence of non-Hodgkin lymphoma (NHL) in early life has increased in recent decades, but the relevant risk factors remain largely unknown. We examined perinatal and family risk factors for NHL in childhood through young adulthood. Methods: We conducted a national cohort study of 3 571 574 individuals born in Sweden in 1973-2008 who were followed for incidence of NHL through 2009

In order to reduce its environmental impact, the chemical industry no longer produces base chemicals such as ethylene, solely from fossil, but also from biomass-based feedstocks. However, a biomass option suitable for one region might not be as suitable for another region due to, e.g., long transport and the related environmental. Therefore, local biomass alternatives and the environmental impact

In this paper, we introduce a time-frequency spectral estimator for smooth spectra, allowing for irregularly sampled measurements. A non-parametric representation of the time dependent (TD) covariance matrix is formed by assuming that the spectrum is piecewise linear. Using this representation, the time-frequency spectrum is then estimated by solving a convex covariance fitting problem, which also

The European Medicines Agency does not recommend the use of hydroxyethyl starch-based volume replacement solutions in critically ill patients due to an increased risk of renal failure. However, this recommendation is questionable for its perioperative use. Several recent randomised controlled studies do not indicate a risk for renal failure-not even after high-risk surgery. Human albumin is used i

Objective : To determine the association between health-risk behaviors and a history of sexual coercion among urban Chinese high school students. Design : A cross-sectional study was performed among 109,754 high school students who participated in the 2005 Chinese Youth Risk Behavior Survey. Data were analyzed for 5,215 students who had experienced sexual intercourse (1,483 girls, 3,732 boys). Mul

Within the last decade, laser-ion acceleration has become a field of broad interest. The possibility to generate short proton- or heavy ion bunches with an energy of a few tens of MeV by table-top laser systems could open new opportunities for medical or technical applications. Nevertheless, today's laser-acceleration schemes lead mainly to a temperature-like energy distribution of the accelerated

Introduction: There is a shortage of tools designed for use by occupational therapy practice in Arabic-speaking countries. The purpose of this study was to translate and cross-culturally adapt the original Satisfaction with Daily Occupations tool to Arabic and assess the psychometric properties of the adapted tool. Method: A cross-cultural adaptation process was performed. Face, content, and crite

In order to promote phase separation and properties of anion-exchange membranes (AEMs)we have prepared polysulfones with an exceptionally high local concentration of imidazolium groups. Statistical copolymers containing single dioxyphenylene rings directly functionalized with four cationic groups were synthesized by polycondensations of 4,4’-dichlorodiphenylsulfone, 4,4′-isopropylidenediphenol and

BACKGROUND: To explore the level of physical activity in a population based sample of older adults; to analyze the influence of pain characteristics and fear-avoidance beliefs as predictors of physical activity among older adults reporting chronic pain. METHODS: Demographics, pain characteristics (duration, intensity), physical activity, kinesiophobia (excessive fear of movement/(re) injury), se

We report on the particle assisted synthesis of core-shell AlP-GaP nanowires by use of metal-organic vapor phase epitaxy. The core-shell approach is chosen such as to stabilize the AlP which is highly sensitive to water. The nanowires were investigated by scanning electron microscopy, transmission electron microscopy, X-ray diffraction, and Raman spectroscopy. These nanowires have an indirect band

Stable walking depends on the coordination of multiple biomechanical degrees of freedom to ensure the dynamic maintenance of whole-body equilibrium as well as continuous forward progression. We investigated adult age-related differences in whole-body coordination underlying stabilization of center of mass (CoM) position and step pattern during locomotion. Sixteen younger (20-30 years) and 16 healt

This thesis deals with manifold learning techniques and their application in gene expression data analysis. Manifold learning is the study of methods that aim to infer geometrical structure from data sampled from manifolds, enabling nonlinear solutions to various machine learning tasks. Gene expression data analysis is the analysis of measurements of the abundance of gene products from a set of ge

Since 1984, 577 knee arthroplasty operations were performed in Al Razi Orthopedic hospital in Kuwait. An increase in the number of these operations occurred during the last four years and in 2007 there were almost 100 knee arthroplasty operations performed. Six out of seven operated patients were female. The mean age at operation was 67 years for male and 62 years for female patients. The vast maj

Cultivated fields and forests in South China are experiencing serious damage due to invasive alien plants. We investigated the relation between DNA C-values and invasiveness. The DNA C-values of 23 species ranged from 0.39 pg to 3.37 pg. Herbs, perennials and native species had higher mean DNA C-values than shrubs, annuals and invasive alien species. DNA C-values decreased with increasing invasive

Locus Celebris – the Church, Monastery and Manor of Dalby actualized: An introduction to the common view on Dalby, to the research history and mediation of the place, to the international conference 24-27 April 2011 in Dalby and finally also an introduction to the conference publication.

We evaluated the seasonality of CO2 fluxes simulated by nine terrestrial ecosystem models of the TRENDY project against (1) the seasonal cycle of gross primary production (GPP) and net ecosystem exchange (NEE) measured at flux tower sites over different biomes, (2) gridded monthly Model Tree Ensembles-estimated GPP (MTE-GPP) and MTE-NEE obtained by interpolating many flux tower measurements with a

All is a 17-kDa chromosomally encoded outer membrane protein that mediates serum resistance (complement resistance) in the pathogenic Yersiniae (Yersinia pestis, Y. enterocolitica, and Y. pseudotuberculosis). In this article, we demonstrate that Y pseudotuberculosis Ail from strains PB1, 2812/79, and YPIII/pIB1 (serotypes O:1a, O:1b, and O:3, respectively) can bind the inhibitor of the classical a

Although the association between cancer and venous thromboembolism (VTE) has long been known, the mechanisms are poorly understood. Circulating tissue factor-bearing extracellular vesicles have been proposed as a possible explanation for the increased risk of VTE observed in some types of cancer. The International Society for Extracellular Vesicles (ISEV) and International Society on Thrombosis an

This thesis is based on four projects focused on the Axl receptor tyrosine kinase (RTK) and microRNAs in clear cell renal cell carcinoma (ccRCC) and in prostate cancer (PCa). Paper I focuses on differentially expressed microRNAs in ccRCC. We used bioinformatics methods to identify candidate microRNAs in a publically available cohort of ccRCC, which were measured in a cohort of 198 RCC tumors. Impo
