Hematopoiesis is a lifelong, dynamic process in which a small number of pluripotent hematopoietic stem cells (HSC) residing in the bone marrow (BM) give rise to billions of mature blood cells of both myeloid and lymphoid origin each day. This enormous capacity of HSC has been utilized in BM transplantations for 4 decades and is also very important for future gene therapy. Understanding what molecu
The effects of avian malaria parasites of the genus Plasmodium on their hosts are insufficiently understood. This is particularly true for malarial co-infections, which predominant in many bird populations. We investigated effects of primary co-infection of Plasmodium relictum (lineage SGS1) and Plasmodium ashfordi (GRW2) on experimentally infected naive juveniles of siskin Spin us spinus, crossbi
Objectives: To estimate intra- and inter-observer reproducibility and reliability of assessment of the color content in adnexal masses at color/power Doppler ultrasound examination for observers with different levels of experience, and to determine if they change after a consensus meeting. Methods: Digital clips with color/power Doppler information of 103 adnexal masses were evaluated independentl
Identifying the genes that underlie phenotypic variation in natural populations, and assessing the consequences of polymorphisms at these loci for individual fitness are major objectives in evolutionary biology. Yet, with the exception of a few success stories, little progress has been made, and our understanding of the link between genotype and phenotype is still in its infancy. For example, alth
There has been little development regarding analysis of polonium (Po) in environmental samples since the 1960ies. This is due to the straightforward spontaneous deposition of this element on silver (Ag), nickel (Ni) or copper (Cu) without any radiochemical separation. For many years, no radiochemical yield determinant was used and it was generally supposed that the yield was 100% after two deposit
Processes of rapid radiation among unicellular eukaryotes are much less studied than among multicellular organisms. We have investigated a lineage of cold-water microeukaryotes (protists) that appear to have diverged recently. This lineage stands in stark contrast to known examples of phylogenetically closely related protists, in which genetic difference is typically larger than morphological diff
G-protein-regulated inward-rectifier potassium channel 2 (GIRK2) is reported to be expressed only within certain dopamine neurons of the substantia nigra (SN), although very limited data are available in humans. We examined the localization of GIRK2 in the SN and adjacent ventral tegmental area (VTA) of humans and mice by using either neuromelanin pigment or immunolabeling with tyrosine hydroxylas
Background Various genome-wide association studies (GWAS) have been done in ischaemic stroke, identifying a few loci associated with the disease, but sample sizes have been 3500 cases or less. We established the METASTROKE collaboration with the aim of validating associations from previous GWAS and identifying novel genetic associations through meta-analysis of GWAS datasets for ischaemic stroke a
M Hagelsteen mfl LTHs 9:e Pedagogiska Inspirationskonferens, 15 december 2016 Abstract—Teaching students is one of the main tasks of LTH, as thousands of students engage on their engineering studies at the faculty every year. The funding for teaching these students is an essential source of income for LTH, but in recent years there has been an increased worry for diminishing financing for lecturin

An outbreak of suspected contact dermatitis among subway construction workers was suspected to be due to a new bisphenol A/F-based epoxy resin system (ERS). The construction workers used ERSs during the insertion of iron bars into concrete walls. The objective of the study was to determine the components (if any) of the ERS responsible for the contact allergy. Patch testing was performed on 20 of
In this article the organization and functional details of the extracellular matrix, with particular focus on cartilage, are described. All tissues contain a set of molecules that are arranged to contribute structural elements. Examples are fibril-forming collagens forming major fibrillar networks in most tissues. The assembly process is regulated by a number of proteins (thrombospondins, LRR-prot
A simple method is tested for scaling climate-extreme results from high resolution regional climate models (RCMs) to time-periods and emission scenarios for which the RCMs have not been run. The 30 yr mean relationships between indicators of extremes (IoEs) and annual mean daily maximum temperature (T-xa) are investigated. Such relationships from the UK Met Office Hadley Centre RCM HadRM3P, along
Reconstructions of solar activity prior to AD1600 rely on estimates of the past production rates of cosmogenic radionuclides in the Earth’s atmosphere. These rates are modulated by the strength of the solar magnetic field and the intensity of the Earth’s geomagnetic dipole. One of the largest uncertainties associated with these reconstructions originates from palaeointensity data and to show how e
Popular Abstract in Swedish Stroke är en av de ledande dödsorsakerna i västvärlden och det finns idag ingen behandling för funktionell återställning. Efter stroke ökar den striatala neurogenesen och de nybildade neuroblasterna vandrar mot det skadade området. Denna respons har ansetts vara av akut och övergående art. I denna avhandling har en modell av experimentell stroke använts (2 h of middle cStroke is a leading cause of death and disability for which there is no treatment for functional recovery. Following stroke, striatal neurogenesis is increased, with newly formed neuroblasts migrating towards the damage. This response has so far been considered acute and transient. In this thesis, a model of experimental stroke (2 h of middle cerebral artery occlusion, MCAO) used to study three a

Background: The risk for coronary events may rise during acute infection. Perturbation in coronary endothelial function emerges as one important link. We investigated whether simvastatin could protect the coronary arterial function from the adverse effects of acute infection in swine. Methods: Coronary endothelium-dependent and -independent vasomotor responses were assessed by Doppler velocimetry
Mycorrhizal symbioses -- the union of roots and soil fungi -- are universal in terrestrial ecosystems and may have been fundamental to land colonization by plants1,2. Boreal, temperate, and montane forests all depend upon ectomycorrhizae1. Identification of the primary factors that regulate symbiotic development and metabolic activity will therefore open the door to understanding the role of 2 ect
The recognition of a strong etiological relationship between infection with high-risk human papillomavirusses and cervical cancer has prompted research to develop and evaluate prophylactic and therapeutic vaccines. One prophylactic quadrivalent vaccine using L1 virus-like particles (VLP) of HPV 6, 11, 16 and 18 is available on the European market since the end of 2006 and it is expected that a sec
