Despite rapid advances in mapping genetic drivers and gene expression changes in hematopoietic stem cells (HSCs), few studies exist at the protein level. We perform a deep, multi-omics characterization (epigenome, transcriptome, and proteome) of HSCs in a mouse model carrying a loss-of-function mutation in Tet2, a driver of increased self-renewal in blood cancers. Using state-of-the-art, multiplex

Discovering topological quantum materials that combine nontrivial topology with large bandgaps and experimentally accessible signatures remains a central pursuit in condensed matter physics. We demonstrate, through first-principles calculations and tight-binding modeling, that pyrite-type osmium disulfide (OsS2) is a fragile topological insulator (FTI) characterized by an exceptionally large direc

BACKGROUND: The EAT-Lancet planetary health diet emphasises plant-based foods while including moderate amounts of animal-sourced foods. Simulation-based modelling studies suggest that the diet can provide adequate micronutrients, but concerns remain about potential deficiencies as studies have used different methodologies and few have assessed nutrient intakes using both dietary and biomarker data

This systematic literature review investigates the relationship between air pollution exposure and inflammatory bowel disease (IBD), encompassing Crohn's disease (CD) and ulcerative colitis (UC). Despite the growing concern over air pollution's impact on various health outcomes, studies specifically addressing effects on the digestive system, particularly IBD, are relatively rare. This review aims

Recent years have seen a surge of interest in exceptional points in open quantum systems. The natural approach in this area has been the use of Markovian master equations. While the resulting Liouvillian EPs have been seen in a variety of systems and have been associated to numerous exotic effects, it is an open question whether such degeneracies and their peculiarities can persist beyond the vali

Aims: Using a longitudinal approach, the aim of this study was to examine whether baseline engagement in arts and culture was associated with a decline from ‘Good’ to ‘Poor’ health at follow-up. Methods: Self-rated health (SRH) and engagement in six cultural activities among randomly selected Danish adults (⩾15 years) were assessed using data from the Danish Health and Wellbeing Survey in 2019. On

Inter-arm blood pressure differences (IABPDs) can be caused by atherosclerosis. We investigated 29921 men and women aged 50–64years from the nationwide population-based Swedish CArdio Pulmonary bioImage Study (SCAPIS) to evaluate if IABPD is related to risk factors for atherosclerosis and can be used as a marker of atherosclerosis as evaluated by coronary artery calcium score, arterial segment inv

Coronary artery disease is one of the leading causes of mortality worldwide. While early identification and treatment of major cardiovascular risk factors are crucial, recent data suggest the possibility of non-invasively detecting early stages of coronary atherosclerosis and potentially stabilizing or even reversing the burden of atherosclerosis with innovative and existing treatments. Moreover,

Innate-like T cells (ILTCs) link innate immune responses with adaptive immune functions. This group includes invariant natural killer T (iNKT) cells, mucosa-associated invariant T (MAIT) cells, and γδ T cells. ILTCs detect transformed or stressed cells via non-classical antigen presentation pathways. For example, iNKT cells recognize CD1d-presented glycolipids, MAIT cells respond to MR1-presented

Tumor necrosis factor (TNF) was long cast as a hematopoiesis villain, driving bone marrow and hematopoietic stem cell (HSC) suppression. We now see that TNF's effects are cell type-, context-, and time-dependent. Rather than being simply "bad," TNF can prune progenitors while transiently reprogramming HSCs without sacrificing long-term regenerative capacity.

BACKGROUND Clonal hematopoiesis of indeterminate potential (CHIP) and clonal cytopenia of undetermined significance (CCUS) are defined by somatic mutations in genes associated with myeloid neoplasms (MN) at a variant allele fraction (VAF) of 0.02 or greater in the absence and presence of cytopenia, respectively. CHIP/CCUS is highly prevalent in adults, and defining predictors of MN risk would aid

Background: Breast cancer polygenic risk scores (PRS) and traditional risk models (e.g., the Gail model [Gail]) are known to contribute largely independent information, but it is unclear how the overlap varies by ancestry, age, disease type (invasive breast cancer, DCIS), and risk threshold. Methods: In a retrospective case–control study, we evaluated risk prediction performance in 180,398 women (

Hedgehog (Hh) signaling is essential for embryonic development and tissue homeostasis in organisms. However, Caenorhabditis elegans lacks canonical Hh signaling due to the absence of key components, such as smoothened (SMO) and obvious Hh ligands. Despite this, C. elegans retains Patched homologs, ptc-1 and ptc-3, which have specialized independent functions. Although ptc-1 is predominantly ex

Taurine, an amino sulfonic acid abundant in seafood and meat, has been proposed to have a potential role in the prevention of metabolic dysfunction-associated steatotic liver disease (MASLD) due to its antioxidant and anti-inflammatory properties. However, the association between dietary taurine intake and MASLD remains unclear in human populations. Also, data on dietary taurine intake among adult

Background: Standardized definitions of autoimmune disease (AD) are lacking. Therefore, we aim to propose a definition of AD for register-based research and estimate the burden of AD in Sweden as registered in the National Patient Register (NPR) from 1980 to 2023. Methods: Leveraging the NPR, we defined AD as having at least two relevant International Classification of Diseases (ICD) codes represe

An abdominal aortic aneurysm (AAA) is defined as aortic diameter ≥30 mm measured by ultrasound. AAA prevalence increases with age and is higher in men, but has decreased during the last decades, related to lower smoking rates. Tobacco smoking, concomitant atherosclerosis, arterial hypertension, and family history are the most common risk factors. AAA has atherosclerotic, inflammatory, apoptotic, a
