This paper develops a new approach in the analysis of the Camassa-Holm equation. By introducing a new set of independent and dependent variables, the equation is transformed into a semilinear system, whose solutions are obtained as fixed points of a contractive transformation. These new variables resolve all singularities due to possible wave breaking. Returning to the original variables, we obtai
Plants of Pinus spp. were grown in observation chambers with the mycorrhizal fungi Suillus bovinus, Pisolithus tinctorius or Paxillus involutus. After interconnecting mycelial systems had developed between plants, individual hosts in some chambers of each species were fed with 14CO2. Mycelia from radioactively labelled and unlabelled chambers were harvested and their carbohydrates were extracted,
Since July 2007, the world economy has experienced a severe financial crisis that originated in the U.S. housing market. Subsequently, the crisis has spread to financial sectors in European and Asian economies and led to a severe worldwide recession. The existing literature on financial crises rarely distinguishes between factors that create the original strain on the financial sector and factors
Rhesus Rhadinovirus (RRV) is currently the closest known, fully sequenced homolog of human Kaposi's sarcoma-associated herpesvirus (KSHV). Both these viruses encode complement inhibitors: KSHV-complement control protein (KCP) and RRV-complement control protein (RCP). Previously we characterized in detail the functional properties of KCP as complement inhibitor. Herein, we performed comparative ana
Health has been a central concept in nursing science since the 18th century but the holistic concept of health that includes both the body and the soul, still has to be clarified. The concept of health is often unclear and represents an unreachable ideal state that can be hard to use as a realistic goal in nursing care. The aim of this study was to describe how the patient perceives the concept of
INTRODUCTION: Patients with ulcerative colitis and primary sclerosing cholangitis have an increased risk of developing carcinoma both in the bile ducts and in the colon. PURPOSE: To investigate whether this patient group also has an increased risk of developing atrophy and neoplasia in the deal pouch mucosa after construction of a pelvic pouch with an ileoanal anastomosis or a continent Kock ileos
The exploding progress in genomic technology and knowledge now opens the possibility to actually identify the molecular mechanisms in disease. However, inflammatory diseases such as rheumatoid arthritis (RA) and multiple sclerosis (MS), are complex and polygenic and remain a challenge. One possible shortcut could be the use of inbred animals as models for RA and MS for the genetic analysis. These
OBJECTIVE: Previous experiments have shown that addition of fragmented fibronectin can induce cartilage chondrolysis. In this study we investigated the fate of the collagen- and cell-binding molecules Cartilage oligomeric matrix protein (COMP) and chondroadherin. DESIGN: Equine articular cartilage explants were stimulated with the C-terminal and the N-terminal heparin-binding fragments of fibronec
Major practical constraints on neural grafting in Parkinson's disease are the shortage of human donor tissue and the great loss of dopamine neurons during the grafting procedure. The vast majority of implanted embryonic dopamine neurons are believed to die within a few days of transplantation surgery, at least in part through apoptosis. We have previously found that survival of nigral grafts in ro
High-resolution palaeoecological proxies of pollen, macrofossils and diatoms from an isolation lake provide a long-term record of the Holocene landscape history and shoreline displacement on the Biskopsmala Peninsula in central Blekinge, SE Sweden. During the Preboreal/Boreal transition, the peninsula was sparsely vegetated by woodlands, along with lateglacial dwarf shrub/steppe communities. The l
I give a very short introduction to chiral perturbation theory and an overview of the next-to-next-to-leading order three-flavour calculations done. I discuss those relevant for an improvement in the accuracy of the measurement of Vus in more detail. One major conclusion is that all needed p6 low energy constants can be obtained from experiment via the scalar form-factor in K
Most of the Nordic region was ice-covered during the last (Weichselian) glaciation. During the postglacial period, plant and animal species recolonized the region from several directions and the geographic structuring of genetic variation within Nordic species may still contain a historic component that reflects patterns of postglacial immigration. The present investigation of 69 populations of Si
Interleukin-6 (IL6) is a growth and survival factor in human prostate cancer (PCa) cells with aggressive phenotypes and has been implicated in the progression of hormone refractory PCas. In the present study, we characterized the IL6-triggered PI3K/Akt and MAPK/Erk signaling. We identified the A-type cyclin, cyclin A1 as an important downstream target of PI3K/Akt. Treatment of cells with PI3K inhi
Sulfate adsorption is an important process when modeling the dynamics of recovery from acidification. In the dynamic soil chemistry model SAFE sulfate adsorption is modeled by a pH and sulfate concentration dependent isotherm. This isotherm has been parameterized by fitting it to data from batch experiments on soil samples using multiple linear regression. The soil samples were from the B-horizon
Objectives Cervical cancer is one of the most common forms of cancer among women. Cytological screening and follow-up are potentially effective procedures for preventing the development of – and mortality from – cervical cancer. The purpose of this study was to investigate the screening history of women diagnosed with cervical cancer with the aim of improving the screening programme. Study design
