“Tin-oxo cage” organometallic compounds are considered as photoresists for extreme ultraviolet (EUV) photolithography. To gain insight into their electronic structure and reactivity to ionizing radiation, we trapped bare gas-phase n-butyltin-oxo cage dications [(BuSn)12O14(OH)6]2+ in an ion trap and investigated their fragmentation upon soft X-ray photoabsorption by means of mass spectrometry. In
Oral biofilms, comprising hundreds of bacteria and other microorganisms on oral mucosal and dental surfaces, play a central role in oral health and disease dynamics. Streptococcus oralis, a key constituent of these biofilms, contributes significantly to the formation of which, serving as an early colonizer and microcolony scaffold. The interaction between S. oralis and the orally predominant mucin
Thyroid cancer (TC) is substantially more common in women than in men, pointing to a possible role of sex steroid hormones. We investigated the association between circulating sex steroid hormones, sex hormone binding globulin (SHBG) and the risk of differentiated TC in men and women within the European Prospective Investigation into Cancer and nutrition (EPIC) cohort. During follow-up, we identif
The introduction of atomic layer deposition (ALD), to the microelectronics industry has introduced a large number of new possible materials able to be deposited in layers with atomic thickness control. One such material is the high-κ oxide HfO2; thermally stable and ultrathin HfO2 films deposited by ALD are a significant contender to replace SiO2 as the gate oxide in capacitor applications. We pre
Streptococcus pyogenes can cause invasive disease with high mortality despite adequate antibiotic treatments. To address this unmet need, we have previously generated an opsonic IgG1 monoclonal antibody, Ab25, targeting the bacterial M protein. Here, we engineer the IgG2-4 subclasses of Ab25. Despite having reduced binding, the IgG3 version promotes stronger phagocytosis of bacteria. Using atomic
Background: Women with mild breast cancer-related arm lymphedema (BCRAL) mostly receive treatment with compression garments and instructions in self-care to prevent the progression of lymphedema. However, wearing a compression garment may be experienced as negative and may affect health-related quality of life (HRQOL) more than the lymphedema itself. The aim of this study was to investigate if the
Purpose: Compared with conventional dose rate irradiation (CONV), ultrahigh dose rate irradiation (UHDR) has shown superior normal tissue sparing. However, a clinically relevant widening of the therapeutic window by UHDR, termed “FLASH effect”, also depends on the tumor toxicity obtained by UHDR. Based on a combined analysis of published literature, the current study examined the hypothesis of tum
Denna avhandling undersöker hur mer jämlika och inkluderande livsmiljöer kan uppnås genom att använda Universal Utformning (UU) för att införliva mänsklig mångfald i alla stadier av planering och byggande. Det pågående utanförskapet av personer med funktionsnedsättning från den byggda miljön beror inte på bristande kunskap om hur man kan åtgärda befintliga hinder eller om hur man undviker att skap
Molecular junctions offer significant potential for enhancing thermoelectric power generation. Quantum interference effects and associated sharp features in electron transmission are expected to enable the tuning and enhancement of thermoelectric properties in molecular junctions. To systematically explore the effect of quantum interferences, we designed and synthesized two new classes of porphyri
Cancer cells evade the immune system by downregulating antigen presentation. Although immune checkpoint inhibitors (ICI) and adoptive T-cell therapies revolutionized cancer treatment, their efficacy relies on the intrinsic immunogenicity of tumor cells and antigen presentation by dendritic cells. Here, we describe a protocol to directly reprogram murine and human cancer cells into tumor-antigen-pr
BackgroundProenkephalin A 119-159 (PENK) is freely filtered in the glomerulus with plasma levels correlating with glomerular filtration rate. Therefore, PENK has been proposed as an early indicator of acute kidney injury (AKI) although its performance is dependent on the clinical setting. This meta-analysis aimed to investigate the correlation between PENK levels and the development of AKI.Methods
Peripheral tolerance is regulated by different types of regulatory T cells, including CD1-restricted T cells and CD4+CD25+ regulatory T (Treg) cells. This thesis has focused on the interactions between T cells and antigen presenting cells (APCs) and the immunregulatory function of TGF-b as two important factors regulating differentiation and activation of T cells in the periphery. In the first par
The aims of this study were: to compare the cartilaginous outline of the femoral head obtained on arthrograms with those on MR images and to correlate it to the bony head outlines on conventional radiograps; to study early, postoperative cartilaginous and bony remodeling of the femoral head, after proximal femoral varus derotation extension osteotomy, with MR imaging and conventional radiography;
An algorithm specific digital signal processor is a powerful alternative to a general purpose signal processor for demanding specifications such as high throughput, low power, small size, etc. These properties are achieved as the processor architecture is tailored to the algorithm as opposed to the general purpose architecture which must suit a wide range of algorithms. The increased performance i
