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
Antipsychotic drugs (APD) are commonly prescribed to people living with dementia (PwD) to manage behavioral and psychological symptoms of dementia (BPSD), despite well-documented safety concerns. International guidelines recommend non-pharmacological interventions as first-line treatment, yet APDs remain widely used. This systematic review and meta-analysis synthesize current evidence on the conse
Tryptophan is an essential amino acid for the human body and is crucial for protein synthesis. It is primarily metabolized through the kynurenine, 5-hydroxytryptamine, and indole pathways. The various bioactive compounds produced through tryptophan metabolism can regulate a range of physiological functions, including digestive, metabolic, immune responses, and neurological functions.
