Journal article (peer-reviewed)abstract
- Epigenetic code modifications by histone deacetylase inhibitors (HDACi) have been proposed as potential new therapies for lymphoid malignancies. Diffuse large B-cell lymphoma (DLBCL) is the most common type of aggressive lymphoma for which standard first line treatment is the chemotherapy regimen CHOP (cyclophosphamide, doxorubicin, vincristine and prednisone) combined with the monoclonal anti-CD20 antibody rituximab (R-CHOP). The HDACi valproate, which has for long been utilized in anti-convulsive therapy, has been shown to sensitize to chemotherapy in vitro. Valproate upregulates expression of CD20 in lymphoma cell lines; therefore, 48 hour pre-treatment with valproate before first line R-CHOP in DLBCL stages II-IV is evaluated in the phase I clinical trial VALFRID; Valproate as First line therapy in combination with Rituximab and CHOP in Diffuse large B-cell lymphoma.

In: New Biotechnology. - : Elsevier BV. - 1876-4347 .- 1871-6784.
-
Research review (peer-reviewed)abstract
- The REvolutionary Approaches and Devices for Nucleic Acid analysis (READNA) project received funding from the European Commission for 4 1/2 years. The objectives of the project revolved around technological developments in nucleic acid analysis. The project partners have discovered, created and developed a huge body of insights into nucleic acid analysis, ranging from improvements and implementation of current technologies to the most promising sequencing technologies that constitute a 3(rd) and 4(th) generation of sequencing methods with nanopores and in situ sequencing, respectively.

A holistic and experimentally-based view on recycling of off-gas dust within the integrated steel plant
- 2018

Journal article (peer-reviewed)abstract
- Ore-based ironmaking generates a variety of residues, including slags and fines such as dust and sludges. Recycling of these residues within the integrated steel plant or in other applications is essential from a raw-material efficiency perspective. The main recycling route of off-gas dust is to the blast furnace (BF) via sinter, cold-bonded briquettes and tuyere injection. However, solely relying on the BF for recycling implicates that certain residues cannot be recycled in order to avoid build-up of unwanted elements, such as zinc. By introducing a holistic view on recycling where recycling via other process routes, such as the desulfurization (deS) station and the basic oxygen furnace (BOF), landfilling can be avoided. In the present study, process integration analyses were utilized to determine the most efficient recycling routes for off-gas dust that are currently not recycled within the integrated steel plants of Sweden. The feasibility of recycling was studied in experiments conducted in laboratory, pilot, and full-scale trials in the BF, deS station, and BOF. The process integration analyses suggested that recycling to the BF should be maximized before considering the deS station and BOF. The experiments indicated that the amount of residue that are not recycled could be minimized.

Development and Application of Proximity Assays for Proteome Analysis in Medicine
- 2018
-
Doctoral thesis (other academic/artistic)abstract
- Along with proteins, a myriad of different molecular biomarkers, such as post-translational modifications and autoantibodies, could be used in an attempt to improve disease detection and progression. In this thesis, I build on several iterations of the proximity ligation assay to develop and apply new adaptable methods to facilitate detection of proteins, autoantibodies and post-translational modifications.In paper I, we present an adaptation of the solid-phase proximity ligation assay (SP-PLA) for the detection of post-translational modification of proteins (PTMs). The assay was adapted for the detection of two of the most commons PTMs present in proteins, glycosylation and phosphorylation, offering the encouraging prospect of using detection of PTMs in a diagnostic or prognostic capacity. In paper II, we developed a variant of the proximity ligation assay using micro titer plate for detection and quantification of protein using optical density as readout in the fluorometer, termed PLARCA. With a detection limit considerably lower than ELISA, PLARCA detected femtomolar levels of these proteins in patient samples.In paper III, we aim to compare detection values of samples collected from earlobe capillary, venous plasma, as well as capillary plasma stored in dried plasma spots (DPS) assessed with a 92-plex inflammation panel using multiplex proximity extension assay (PEA). Despite the high variability in protein measurements between the three sample sources, we were able to conclude that earlobe capillary sampling is a suitable less invasive alternative, to venipuncture.In paper IV, we describe the application of PLARCA and proximity extension assay (PEA) for the detection of GAD65 autoantibodies (GADA). Thus, offering highly sensitive and specific autoimmunity detection.

A General Method for Rapid Determination of Antibiotic Susceptibility and Species in Bacterial Infections
- 2015
-
In: Journal of Clinical Microbiology. - 0095-1137 .- 1098-660X. ; 53:2, s. 425-432
-
Journal article (peer-reviewed)abstract
- To ensure correct antibiotic treatment and reduce the unnecessary use of antibiotics, there is an urgent need for new rapid methods for species identification and determination of antibiotic susceptibility in infectious pathogenic bacteria. We have developed a general method for the rapid identification of the bacterial species causing an infection and the determination of their antibiotic susceptibility profiles. An initial short cultivation step in the absence and presence of different antibiotics was combined with sensitive species-specific padlock probe detection of the bacterial target DNA to allow a determination of growth (i.e., resistance) and no growth (i.e., susceptibility). A proof-of-concept was established for urinary tract infections in which we applied the method to determine the antibiotic susceptibility profiles of Escherichia coli for two drugs with 100% accuracy in 3.5 h. The short assay time from sample to readout enables fast appropriate treatment with effective drugs and minimizes the need to prescribe broad-spectrum antibiotics due to unknown resistance profiles of the treated infection.

Highly sensitive and specific protein detection via combined capillary isoelectric focusing and proximity ligation
- 2017

Journal article (peer-reviewed)abstract
- Detection and quantification of proteins and their post-translational modifications are crucial to decipher functions of complex protein networks in cell biology and medicine. Capillary isoelectric focusing together with antibody-based detection can resolve and identify proteins and their isoforms with modest sample input. However, insufficient sensitivity prevents detection of proteins present at low concentrations and antibody cross-reactivity results in unspecific detection that cannot be distinguished from bona fide protein isoforms. By using DNA-conjugated antibodies enhanced signals can be obtained via rolling circle amplification (RCA). Both sensitivity and specificity can be greatly improved in assays dependent on target recognition by pairs of antibodies using in situ proximity ligation assays (PLA). Here we applied these DNA-assisted RCA techniques in capillary isoelectric focusing to resolve endogenous signaling transducers and isoforms along vascular endothelial growth factor (VEGF) signaling pathways at concentrations too low to be detected in standard assays. We also demonstrate background rejection and enhanced specificity when protein detection depended on binding by pairs of antibodies using in situ PLA, compared to assays where each antibody preparation was used on its own.
