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 (

Electrospinning is a versatile technique for manufacturing micro-nano diameter fibers and has been used extensively for tissue engineering in vivo and advanced cell culture in vitro. Standard means of seeding cells onto such substrates typically offer no control over cell distribution, yielding dispersed, heterogeneous and low concentrations of cells. In this article, we investigate the viability

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

Light-emitting diodes (LEDs) are widely applied in fields ranging from solid-state lighting and high-resolution displays to optical communication and sensing. Despite their remarkable technological development, conventional thin-film LEDs remain constrained by strain-induced defects from lattice mismatch and restricted light extraction efficiency due to total internal reflection. Exploration of al

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

IntroductionForensic assessments of whether an injury would have been life-threatening often rely on empirical knowledge rather than evidence-based criteria. To address this gap, we applied the validated trauma scoring system New Injury Severity Score (NISS) to estimate mortality risk along the natural course of single stab injuries to the trunk.Methods and materialsWe included 408 survivors and 1

Nickel phosphides are promising earth-abundant, low-cost catalysts for hydrogen/oxygen evolution reactions and CO2 reduction. However, their formation mechanisms remain poorly understood and difficult to control. This particularly applies to mechanisms determining phase evolution, crystallinity, and morphology under reactive conditions, factors that critically influence catalytic activity and stab

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

Background: The use of high-flow oxygen therapy (HFOT) compared with standard low-flow oxygen therapy (LFOT) may improve outcomes in people with oxygen-dependent chronic respiratory failure (CRF). The primary aim of this multicentre trial was to evaluate HFOT in addition to LFOT, compared with regular LFOT in people with CRF due to chronic obstructive pulmonary disease (COPD) or interstitial lung

Streptococcus pneumoniae resists host defenses through multiple surface factors, yet their specific contribution to protection against antimicrobial peptides remains incompletely understood. We examined the role of pneumococcal surface protein A (PspA) and the polysaccharide capsule in protection against the human defensin HNP-1. PspA conferred increased resistance to HNP-1-induced killing, shown

Background: The incidence of pancreatic cancer (PC) and autoimmune diseases (ADs) has been increasing worldwide. While certain associations between specific ADs, such as pancreatitis, and PC have long been well confirmed, population-focused research investigating the broader spectrum of ADs and their relationship with PC risk remains limited. Methods: We implemented a cohort study based on populat

In the present study, the novel family genetic risk score (FGRS) method, a reliable quantification of latent genetic risk, was applied to posttraumatic stress disorder (PTSD) to examine associations between genetic liability and clinical features of PTSD among 3,097,180 individuals in the Swedish national registries. FGRS was calculated based on lifetime PTSD status for first- through fifth-degree

OBJECTIVE: To assess structural changes at peripheral entheses and the association with spinal bone formation in patients with long-standing radiographic axial spondyloarthritis (r-axSpA) overall and stratified by sex. METHODS: Peripheral entheses were examined cross-sectionally using ultrasound (US) in patients fulfilling the modified New York criteria for ankylosing spondylitis (AS) and assessed
