- Although amphiphilic diblock copolymer templating of inorganic materials such as TiO2 is already well investigated, sol-gel synthesis routines for porous silicon and germanium are relatively rare. Therefore, especially in the field of Li-ion batteries, novel synthesis routines with the possibility to tune the silicon and germanium ratio and the morphology in the nanometer regime are of high interest. Here, we demonstrate a synthesis method that allows a change of morphology and elemental composition with minimal effort. We evidence a morphological transformation in the nanometer regime with real space (scanning electron microscopy) and complementary reciprocal space analysis methods (grazing-incidence small-angle X-ray scattering). Although energy-dispersive X-ray spectroscopy (EDS) reveals a considerable amount of oxygen in the thin film, crystalline Ge in the bulk is detected with powder Xray diffraction (PXRD) and Raman spectroscopy. Due to the system's simplicity, chemical mass production options such as roll-to-roll or slot-die printing can also be considered high-yield methods compared to standard synthesis routines.

The European Hematology Association Roadmap for European Hematology Research : a consensus document
- 2016

Ingår i: Haematologica. - Pavia, Italy : Ferrata Storti Foundation (Haematologica). - 0390-6078 .- 1592-8721. ; 101:2, s. 115-208

- The European Hematology Association (EHA) Roadmap for European Hematology Research highlights major achievements in diagnosis and treatment of blood disorders and identifies the greatest unmet clinical and scientific needs in those areas to enable better funded, more focused European hematology research. Initiated by the EHA, around 300 experts contributed to the consensus document, which will help European policy makers, research funders, research organizations, researchers, and patient groups make better informed decisions on hematology research. It also aims to raise public awareness of the burden of blood disorders on European society, which purely in economic terms is estimated at (sic)23 billion per year, a level of cost that is not matched in current European hematology research funding. In recent decades, hematology research has improved our fundamental understanding of the biology of blood disorders, and has improved diagnostics and treatments, sometimes in revolutionary ways. This progress highlights the potential of focused basic research programs such as this EHA Roadmap. The EHA Roadmap identifies nine 'sections' in hematology: normal hematopoiesis, malignant lymphoid and myeloid diseases, anemias and related diseases, platelet disorders, blood coagulation and hemostatic disorders, transfusion medicine, infections in hematology, and hematopoietic stem cell transplantation. These sections span 60 smaller groups of diseases or disorders. The EHA Roadmap identifies priorities and needs across the field of hematology, including those to develop targeted therapies based on genomic profiling and chemical biology, to eradicate minimal residual malignant disease, and to develop cellular immunotherapies, combination treatments, gene therapies, hematopoietic stem cell treatments, and treatments that are better tolerated by elderly patients.

Legitimacy and comprehensibility of work-related assessments and official decisions within the sickness insurance system
- 2022
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The aim of this thesis was to contribute to the development of empirical and theoretical knowledge about the legitimacy and comprehensibility of assessment- and decision-making processes within the sickness insurance system from a client perspective. The focus has been on interactions between clients and other stakeholders within the system, and the extent to which the clients understood and accepted the procedures. In addition, the legitimacy and comprehensibility of the system were studied through the lens of three theoretical concepts: social validity, social insurance literacy (SIL), and moral hazard. For this thesis, a mixed methods approach was adopted, consisting of one quantitative and three qualitative studies, including interviews, files, register data, and a questionnaire. Overall, the findings demonstrates that interactions between clients and other stakeholders were important both for the client’s sick-leave case and for their perceptions of sickness insurance procedures. A continuing dialogue between client and case manager tended to facilitate the client’s understanding and acceptance of the steps taken in the sick-leave process. Furthermore, a client’s perception of the justice of processes in the system was associated with the system’s ability to provide understandable and logical information and procedures. This thesis also demonstrates that assumptions of moral hazard were clearly present and that acts of power and mistrust occurred between stakeholders, as different stakeholders tried to influence the client’s sick-leave process. An acceptable and fair sick-leave process was described by the clients as being one that consisted of relevant procedures, was applicable to the unique client, and was a result of support from other stakeholders. In order to increase the comprehensibility, as well as the legitimacy and fairness, the authorities need to explain and justify a diverse range of steps beyond just the official decisions, so that clients are able to comprehend the what, how, and why of sickness insurance. In terms of SIL, clients’ abilities to obtain, understand, and act on information, did not influence whether they received sickness benefits or their perceived justice. On the other hand, higher scores of perceived justice was associated with high scores of perceived system comprehensibility and being granted sickness benefits. This indicates that what the system does, and what it does not do, influenced clients’ opinions of it, regardless of their own prerequisites.

Tidskriftsartikel (refereegranskat)abstract
- Stromal infiltration is associated with poor prognosis in human colon cancers. However, the high heterogeneity of human tumor-associated stromal cells (TASCs) hampers a clear identification of specific markers of prognostic relevance. To address these issues, we established short-term cultures of TASCs and matched healthy mucosa-associated stromal cells (MASCs) from human primary colon cancers and, upon characterization of their phenotypic and functional profiles in vitro and in vivo, we identified differentially expressed markers by proteomic analysis and evaluated their prognostic significance. TASCs were characterized by higher proliferation and differentiation potential, and enhanced expression of mesenchymal stem cell markers, as compared to MASCs. TASC triggered epithelial–mesenchymal transition (EMT) in tumor cells in vitro and promoted their metastatic spread in vivo, as assessed in an orthotopic mouse model. Proteomic analysis of matched TASCs and MASCs identified a panel of markers preferentially expressed in TASCs. The expression of genes encoding two of them, calponin 1 (CNN1) and tropomyosin beta chain isoform 2 (TPM2), was significantly associated with poor outcome in independent databases and outperformed the prognostic significance of currently proposed TASC markers. The newly identified markers may improve prognostication of primary colon cancers and identification of patients at risk.

- To identify novel genes associated with ALS, we undertook two lines of investigation. We carried out a genome-wide association study comparing 20,806 ALS cases and 59,804 controls. Independently, we performed a rare variant burden analysis comparing 1,138 index familial ALS cases and 19,494 controls. Through both approaches, we identified kinesin family member 5A (KIF5A) as a novel gene associated with ALS. Interestingly, mutations predominantly in the N-terminal motor domain of KIF5A are causative for two neurodegenerative diseases: hereditary spastic paraplegia (SPG10) and Charcot-Marie-Tooth type 2 (CMT2). In contrast, ALS-associated mutations are primarily located at the C-terminal cargo-binding tail domain and patients harboring loss-of-function mutations displayed an extended survival relative to typical ALS cases. Taken together, these results broaden the phenotype spectrum resulting from mutations in KIF5A and strengthen the role of cytoskeletal defects in the pathogenesis of ALS.
