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

Background: Wrist osteoarthritis can cause persistent pain, reduced joint mobility, and difficulty performing daily activities, negatively impacting quality of life. Although patient education and exercise therapy are recommended as first-line treatments for osteoarthritis in other joints, evidence supporting these strategies for wrist osteoarthritis remains limited. This randomized controlled tri

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

Two hydrogen-bonding monomers containing tetraethylene glycol (TEG) chains have been synthesized and characterized. The monomers are based on a bicyclic scaffold appended with either 4H-bonding benzyl-substituted ureidopyrimidinone motifs or 2H-bonding unsubstituted pyrrole-fused ureidopyrimidinone motifs, with the TEG chains introduced with the aim of developing amphiphilic monomers soluble in no

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,

Somatostatin, produced by pancreatic islet δ cells, is a key intra-islet paracrine factor that regulates the secretion of the glucoregulatory hormones insulin and glucagon from β cells and α cells, respectively. Here, we show that glutamate and glucagon released by α cells cooperatively activate neighbouring δ cells through AMPA and glucagon receptors, thereby enabling spatiotemporal feedback cont

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.

PURPOSE: Early administration of beta-lactam antibiotics is a crucial part in the treatment of sepsis and septic shock. Beta-lactams demonstrate time-dependent killing and therefore it is important to optimize the time above the minimal inhibitory concentration (MIC). An extra dose is recommended in threatening/suspected/confirmed septic shock. This study aimed to examine whether patients with sus

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 (
