Solitary fibrous tumor (SFT) is a mesenchymal neoplasm displaying variable morphologic and clinical features. To identify pathogenetically important genetic rearrangements, 44 SFTs were analyzed using a variety of techniques. Chromosome banding and fluorescence in situ hybridization (FISH) showed recurrent breakpoints in 12q13, clustering near the NAB2 and STAT6 genes, and single nucleotide polymo
CONTEXT: Melatonin regulates circadian rhythms and influences glucose metabolism. Altered melatonin secretion may contribute to the pathogenesis of type 2 diabetes (T2D), but prospective population-based evidence is scarce.OBJECTIVE: To examine whether low nocturnal melatonin secretion is associated with an increased risk of incident T2D in adults.METHODS: This prospective cohort study, with follo
Background: Expression of CD25, the IL-2 receptor alpha chain, on human mast cells is primarily associated with aberrant mast cells in clonal mast cell disorders. However, the regulation of CD25 expression in normal, mature tissue-resident mast cells remains poorly understood. Objective: IL-33 is a key modulator of immune responses, including in lung inflammatory conditions. Because mast cells are
Dysregulation of cytokines in the bone marrow microenvironment promotes acute myeloid leukemia cell growth. Due to the complexity and low throughput of in vivo stem-cell based assays, studying the role of cytokines in the bone marrow niche in a screening setting is challenging. Herein, we developed an ex vivo cytokine screen using 11 arrayed molecular barcodes, allowing for a competitive in vivo r
Background: The interaction of allergens and allergen-specific IgE initiates the allergic cascade after crosslinking of receptors on effector cells. Antibodies of other isotypes may modulate such a reaction. Receptor crosslinking requires binding of antibodies to multiple epitopes on the allergen. Limited information is available on the complexity of the epitope structure of most allergens. Object
Purpose: The small molecule inhibitors larotrectinib and entrectinib have recently been approved as cancer agnostic drugs in patients with tumours harbouring a rearrangement of the neurotrophic tropomyosin receptor kinase (NTRK). These oncogenic fusions are estimated to occur in 0.1–3 % of non-small cell lung cancers (NSCLC). Although molecular techniques are most reliable for fusion detection, im
Purpose: To assess the ability of clinical examination, blood biomarkers, electrophysiology, or neuroimaging assessed within 7 days from return of spontaneous circulation (ROSC) to predict poor neurological outcome, defined as death, vegetative state, or severe disability (CPC 3–5) at hospital discharge/1 month or later, in comatose adult survivors from cardiac arrest (CA). Methods: PubMed, EMBASE
Toll-like receptor (TLR) mediated recognition of pathogen associated molecular patterns allows the immune system to rapidly respond to a pathogenic insult. The "danger context" elicited by TLR agonists allows an initially non-immunogenic antigen to become immunogenic. This ability to alter environment is highly relevant in tumor immunity, since it is inherently difficult for the immune system to r
Purpose: The study aimed to investigate expression of epithelial-to-mesenchymal transition (EMT)-related proteins and phenotypes during breast cancer progression and to relate this to patient outcome. Methods: Protein expression patterns of E-cadherin, N-cadherin, twist, and vimentin were examined by immunohistochemistry on formalin-fixed paraffin-embedded samples from primary tumors (PTs) (n = 41
Background: During wound healing processes fibroblasts account for wound closure by adopting a contractile phenotype. One disease manifestation of COPD is emphysema which is characterized by destruction of alveolar walls and our hypothesis is that fibroblasts in the COPD lungs differentiate into a more contractile phenotype as a response to the deteriorating environment. Methods: Bronchial (centra
Ett patent är en immateriell rättighet som medför en ensamrätt för patenthavaren att dra affärsmässig nytta av en viss uppfinning under en begränsad tidsperiod. Den som kränker patenthavarens ensamrätt gör sig skyldig till patentintrång. Vid patentintrång tillhandahåller den svenska patentlagen (1967:837) ett antal olika sanktionsmöjligheter. De primära civilrättsliga sanktionsformerna utgörs av pA patent is a kind of intellectual property right that grants the patent holder an exclusive right to profit from a certain invention for a limited time period. Anyone who violates the patent holder's exclusive right is guilty of patent infringement. In cases of patent infringement the Swedish Patent Act (patentlag 1967: 837) provides a number of different sanction options. The primary civil s
We carried out the first high-resolution transit observations of the exoplanet WASP-49 Ab with Keck/HIRES. Upon custom wavelength calibration we achieve a Doppler RV precision of < 60 m s−1. . This is an improvement in RV stability of roughly 240 m s−1 with respect to the instrument standard. We report an average sodium flux residual of (Formula presented) per cent t (8.0σ) comparable to previous
Drawing from socio-legal studies on technological governance and notions of the pacing problem between law and new technologies, this chapter addresses how generative AI is regulated in the EU AI Act. Specifically, it focuses on implications of the two-tiered approach to General Purpose Artificial intelligence (GPAI) models, where the top tier is adding obligations to producers of so-called “syste
Background: The HYPO-RT-PC trial compared conventionally fractionated radiotherapy with ultra-hypofractionated radiotherapy in patients with localised prostate cancer. Ultra-hypofractionation was non-inferior to conventional fractionation regarding 5-year failure-free survival and toxicity. We aimed to assess whether patient-reported quality of life (QOL) differs between conventional fractionation
CONTEXT: Understanding factors involved in the rate of C-peptide decline is needed to tailor therapies for type 1 diabetes (T1D). OBJECTIVE: Evaluate factors associated with rate of C-peptide decline after a T1D diagnosis in young children. DESIGN: Observational study. SETTING: Academic centers. PARTICIPANTS: A total of 57 participants from the Environmental Determinants of Diabetes in the Young (
Background and aims: Gut transit time is a key modulator of host-microbiome interactions, yet this is often overlooked, partly because reliable methods are typically expensive or burdensome. The aim of this single-arm, single-blinded intervention study is to assess (1) the relationship between gut transit time and the human gut microbiome, and (2) the utility of the a € blue dye' method as an inex
Introduction: Cell-free DNA is an emerging marker of allograft injury, yet its role in the immediate phase of ischemia–reperfusion injury remains incompletely understood.Methods: In this prospective cohort of 127 kidney transplant recipients (86 deceased donors, 41 living donors), intraoperative plasma samples were collected systemically pre-implantation and from the allograft vein postreperfusion
Tissue engineering strategies predominantly consist of the autologous generation of living substitutes capable of restoring damaged body parts. Persisting challenges with patient-specific approaches include inconsistent performance, high costs, and delayed graft availability. Toward developing a one-for-all solution, a more attractive paradigm lies in the exploitation of dedicated cell lines for t
Pulmonary arterial hypertension (PAH) is a life-threatening condition with no cure, making research into its underlying mechanisms critical. The platelet-derived growth factor (PDGF) signaling pathway plays a crucial role in vascular remodeling, a key factor in PAH progression. Anti-PDGF receptor therapies, such as imatinib, show promise but are associated with significant side effects. Recent res
