Vi välkomnar repliken från Carbon Capture Companys vd. Vi, EU, Sveriges regering och Christoffer Bonde delar målet att främja ett starkt och lönsamt skogsbruk som bidrar till klimat­arbetet både genom upptag av växthus­gaser och minskade utsläpp. Vad vi ställer oss kritiska till är den klimat­kompensation som just nu lanseras av företag som Carbon Capture Company, eftersom vi anser att den är dyr,

The molecular mechanism behind affinity maturation is the introduction of point mutations in immunoglobulin (Ig) V genes, followed by the selective proliferation of B cells expressing mutants with increased affinity for antigen. An in vitro culture system was developed in which somatic hypermutation of Ig V genes was sustained in primed B cells. Cognate T cell help and cross-linking of the surface

Priming mice with a chicken gamma globulin (CGG) carrier protein significantly accelerated the onset of somatic mutation in the V chi Ox1 gene when the mice were subsequently immunized with 2-phenyl-5-oxazolone (phOx) coupled to CGG. The first mutations were already detected 7 days after immunization, while in the true primary response, they are not apparent until day 10. It was also found that co

Resting mouse B lymphocytes were stimulated in vitro with lipopolysaccharide, Sepharose-coupled anti-kappa antibodies or a combination of the two. B lymphocytes stimulated with anti-kappa entered the cell-cycle with more rapid kinetics and at a higher frequency than did the corresponding cell population stimulated with lipopolysaccharide. Using cell cycle analysis after DNA staining combined with

A search for an antigen-driven expansion of T lymphocytes in the inflamed joints in rheumatoid arthritis (RA) patients have been going on for decades. We here analyzed the human germinal centre T-cell receptor (TCR) Vbeta gene usage with polymerase chain reaction (PCR) combined with sequence analysis, to address the question of clonality in tonsils and synovial tissue from RA patients. Our data sh

We have studied somatic mutation activity early in a response to 2-phenyl-5-oxazolone coupled to ovalbumin (phOx-OVA). Although the V kappa Ox1 gene rearranged to J kappa 5 is known to predominate in this response, other closely related V kappa genes are involved. We compared the introduction of point mutations into V kappa Ox1 genes and into a set of related V kappa genes rearranged to the same J

The stability of established memory T helper (Th)1/Th2 cells in chronic inflammatory diseases is not clear, and a shift of the cytokine balance could control chronic inflammation. In order to study the regulation of the Th phenotype of memory T cells, polyclonal T-cell lines and clones with a Th1, Th0 or Th2 phenotype were developed from rheumatoid synovial tissue. Th1 [interleukin (IL)-12 + anti-

Somatic mutation activity in immunoglobulin V kappa genes during the response to the hapten 2-phenyl-5-oxazolone was measured in lymph node B-cell populations at various timepoints after footpad immunization. When the V kappa Ox1 genes rearranged to the J kappa 5 segment were amplified from genomic DNA using the polymerase chain reaction and sequenced, somatic mutations could be detected as early

Negative induced polarization (IP) time-domain transients, sign-changing or non-monotonically decaying transients are currently often considered as measurement errors and removed in the data processing. These transients, here named heterodox in the sense of other than generally accepted signals, might originate from measurement errors, inductive effects, or poor signal processing, but synthetic mo

Labeling of proteins with deuterium (2H) is often necessary for structural biology tech-niques, such as neutron crystallography, NMR spectroscopy, and small-angle neutron scattering. Perdeuteration in which all protium (1H) atoms are replaced by deuterium is a costly process. Typ-ically, expression hosts are grown in a defined medium with heavy water as the solvent, which is supplemented with a de

Background How does genetic liability to suicide attempt (SA), suicide death (SD), major depression (MD), bipolar disorder (BD), schizophrenia (SZ), alcohol use disorder (AUD), and drug use disorder (DUD) impact on risk for SA and SD? Methods In the Swedish general population born 1932-1995 and followed through 2017 (n = 7 661 519), we calculate family genetic risk scores (FGRS) for SA, SD, MD, BD

Picosecond ultrasonics, which studies laser-induced high-frequency strain waves, is a reliable and versatile method for nondestructive materials' characterization. Strain waves are generated through a light interaction with charges and their subsequent relaxation, and these waves conceal a wealth of information on the material. However, strain waves are detected through their convolution with a se

To assess (1) global longitudinal strain (GLS) by feature tracking cardiac magnetic resonance (CMR) in the sub-acute and chronic phases after ST-elevation infarction (STEMI) and compare to GLS in healthy controls, and (2) the evolution of GLS and regional longitudinal strain (RLS) over time, and their relationship to infarct location and size. Seventy-seven patients from the CHILL-MI-trial (NCT013

Emotion regulation has been specifically linked to both non-suicidal self-injury (NSSI) and attempted suicide. It is also known that self-harm is disproportionally higher (30–68.4%) in forensic samples than in the general population, yet knowledge about the association between emotion regulation and self-harm in forensic settings is scarce. The purpose of this study was to describe emotion regulat

Purpose: This paper aims to study the effects of different weather conditions on typical concrete work tasks’ productivity. Weather is one important factor that has a negative impact on construction productivity. Knowledge about how weather affects construction works is therefore important for the construction industry, e.g. during planning and execution of construction projects. Design/methodolog

Land surface subsidence due to excessive groundwater pumping is an increasing concern in California, USA. Interferometric Synthetic Aperture Radar (InSAR) is a remote sensing technique for measuring centimeter-to-millimeter surface deformation at 10–100 m spatial resolution. Here, a data-driven approach that attributes deformation to individual depth intervals within an aquifer system by integrati
