Lead is one of the poisonous elements for de-NOx catalysts especially in the case of municipal waste incineration plants. Samples of a commercial selective catalytic reduction catalyst were impregnated with different amounts of Pb(NO3)(2), and their catalytic activities were studied. The XPS and SEM analysis showed higher lead concentration on the outer surface of the monolith than on the inside o
Brent geese were tracked by satellite telemetry from spring staging areas in Denmark to Arctic breeding areas in Svalbard and Greenland in 1997 and 2001. From estimated departure masses and carcass analysis we used flight mechnical theory to estimate maximum flight ranges of both sexes, and remaining stores of fat and protein upon arrival in females. Model predictions suggested that all birds but
Endoglucanases (endo-1,4---glucan-4-glucanohydrolase, EC 3.2.1.4) are industrially important enzymes. In this study endoglucanase I (EGI or Cel7B) of the filamentous fungi Trichoderma reesei has been genetically engineered to investigate the influence of tryptophan rich peptide extensions (tags) on partitioning in an aqueous two-phase model system. EGI is a two-domain enzyme and is composed of a N
Rheumatoid arthritis (RA) is associated with certain MHC class II alleles and is characterized by a chronic autoimmune response in the joints. Using transgenic mice expressing human DR4 (DRB1*0401) and human CD4, but lacking endogenous MHC class II, we show that posttranslational glycosylation of type II collagen (CII) influences the level of T cell tolerance to this candidate cartilage-specific a
With the recent advances towards modern Ion Beam Analysis (IBA), going from one- or few-parameter detector systems to multi-parameter systems, it has been necessary to expand and replace the more than twenty years old CAMAC based system. A new VME multi-parameter (presently up to 200 channels) data acquisition and control system has been developed and implemented at the Lund Ion Beam Analysis Faci
The transcription factor STAT3 is a potential target for the treatment of castration-resistant prostate cancer. Galiellalactone (1), a direct inhibitor of STAT3, prevents the transcription of STAT3 regulated genes. In this study we characterized 6 (GPA512, Johansson, M.; Sterner, O. Patent WO 2015/132396 A1, 2015), a prodrug of 1. In vitro studies showed that 6 is rapidly converted to 1 in plasma
Introduction: The aim of this study is to report the current status of ovarian tissue cryopreservation among alternatives for fertility preservation in the Nordic countries. Material and methods: A questionnaire was sent to 14 Nordic academic reproductive centers with established fertility preservation programs. It covered fertility preservation cases performed up to December 2014, standard proced
The current work focus on the overlay method proposed by Austrell concerning frequency dependence of the dynamic modulus and loss angle that is known to increase more with frequency for small amplitudes than for large amplitudes. The original version of the overlay method yields no difference in frequency dependence with respect to different load amplitudes. However, if the elements in the viscoel
In osteopetrosis, osteoclast dysfunction can lead to deafness, blindness, bone marrow failure, and death. Hematopoietic cell transplantation (HCT) is currently the only curative treatment, but outcome remains disappointing. Although a rapid progression toward HCT is detrimental to prevent further progress of disease manifestations, 70% of cases lack an HLA-matched sibling and require alternative s
Skogar tillhandahåller en mångfald av produkter och tjänster som alla är kopplade till vattenresurser. Träd behöver vatten för att växa och samtidigt förändrar träd kvalitén och kvantiteten av avrinningen genom modifiering av vatten- och näringsämneskretsloppet. Förståelsen av samspelet mellan skog och vatten är grundläggande för att kunna utvärdera konsekvenserna av naturlig och antropogen påverkForests provide multiple products and services which are all are linked to water resources. Trees need water to grow and, at the same time, they change the quality and the quantity of runoff by modifying water and nutrient cycling. The understanding of the interactions between forest and water is fundamental to assess the consequences of natural and anthropogenic pressures, such as climate change
The European Randomised study of Screening for Prostate Cancer (ERSPC) has shown significant reductions in prostate cancer mortality after 9 years and 11 years of follow-up, but screening is controversial because of adverse events such as overdiagnosis. We provide updated results of mortality from prostate cancer with follow-up to 2010, with analyses truncated at 9, 11, and 13 years.
A search for nonresonant new phenomena, originating from either contact interactions or large extra spatial dimensions, has been carried out using events with two isolated electrons or muons. These events, produced at the LHC in proton-proton collisions at root s = 7 TeV, were recorded by the ATLAS detector. The data sample, collected throughout 2011, corresponds to an integrated luminosity of 4.9
Abstract The benefit of exercise for breast cancer-treated women is well documented. However, studies of cardiovascular fitness training for women with breast cancer-related arm lymphedema are rare. The purpose of this study was to investigate the effects of intensive pole walking on arm lymphedema in women treated for breast cancer. Thirty-five women with unilateral lymphedema were included and t
