Autoimmune diseases occur due to the abnormal response of the adaptive immune system towards the body's tissues, recognizing them as foreign and leading to chronic inflammation and harm to the tissues. Toxicologists and other scientists believe that factors such as genes, surroundings, and lifestyle can make autoimmune diseases more likely. Xenobiotics, such as chemical pollutants, drugs, microbes
Proton-translocating NAD(P)+ transhydrogenase (NNT) is highly expressed in cardiac tissue, where it physiologically supports mitochondrial NADPH production. However, under certain pathological conditions, NNT may shift toward consuming the mitochondrial NADPH pool. Although NNT has been implicated in redox homeostasis, its contribution to cardiac function during aging remains uncertain. In this st
Nilsson-Strutinsky cranking calculations on A ≥ 100 Ru and Pd nuclei suggest that, contrary to other mass regions, it should be possible to follow the ground state rotational bands to their termination at spins just above I = 30ℏ and then also to observe other bands which terminate at higher spins.
We reply to the preceding Comment.
Background: Despite recommendations by EU, surveillance of Lyme neuroborreliosis (LNB) is still not fully implemented in all member states, Sweden being one of them. Laboratory-based notifications on positive Borrelia antibody index (AI) in paired cerebrospinal fluid-serum samples alone have been suggested for surveillance of LNB. Objectives: We aim to describe the epidemiology of Lyme borreliosis
Introduction: Strategies for tuberculosis (TB) elimination in low-incidence countries involve screening recent migrants from TB-endemic regions for TB infection (TBI) and providing TB preventive treatment (TPT) to individuals with an increased risk of reactivation. This study aimed to determine TB incidence and identify reactivation risk markers in a cohort of asylum seekers in Sweden after screen
The direct conversion of methane to methanol (DCMM) under continuous flow and atmospheric pressure offers notable environmental benefits and industrial promise, but remains a long-standing challenge due to the difficulty of activating CH4while avoiding overoxidation of methanol. Here, we demonstrate that pure ceria (CeO2), without any metal promoters, enables gas-phase DCMM with up to 80% selectiv
Biotechnologically produced (R)-3-hydroxybutyrate is an interesting pre-cursor for antibiotics, vitamins, and other molecules benefitting from enantioselective production. An often-employed pathway for (R)-3-hydroxybutyrate production in recombinant E. coli consists of three-steps: (1) condensation of two acetyl-CoA molecules to acetoacetyl-CoA, (2) reduction of acetoa
Objective: Clinical autoimmune thyroid disease (AITD), presenting as either hypo- or hyperthyroidism, can occur at any age. Autoantibodies against thyroid peroxidase or thyroglobulin precede the onset of clinical AITD. We aimed to assess factors associated with AITD in children and determine if risk factors for AITD differ among the subset who have developed thyroid autoantibodies. Design: Prospec
Droplets generated by talking and coughing play a major role in the spreading of COVID-19. There is thus a need for accurate measurements of the physical properties of exhaled droplets, including their number, speed and direction.Several challenges are associated with imaging coughed droplets such as high droplet speed near the mouth where both short exposure time to freeze droplet motion and kHz
West Virginia, sitting fully in the eastern US region of Appalachia, has a long history of resource extraction, including salt, timber, coal and oil. In the late 2000s, gas became another popular resource, obtained through hydraulic fracturing. The once-hilly landscape has been flattened, valleys have been filled, and caves have been dug all because of extraction. In this photo essay we document t
Background: To support a victim of violence and establish the correct penalty for the perpetrator, it is crucial to correctly evaluate and communicate the severity of the violence. Recent data have shown these communications to be biased. However, computational language models provide opportunities for automated evaluation of the severity to mitigate the biases. Objective: We investigated whether
GWAS studies have identified hundreds of loci that associate with obesity and type 2 diabetes. However, the functional relevance of the genetic variants, and their impact on disease or traits, is largely unknown. To address those questions, we applied functional genomics approaches to study genetic variants pertinent to obesity and type 2 diabetes-related traits.In paper I, we demonstrate that rs6
Background: Since the first version of the dietary inflammatory index (DII®) developed in the past decade, several other versions have been developed. However, to date no study has attempted to compare these versions with respect to their associations with biomarkers of inflammation. Objective: We aimed to investigate the relationship between four dietary inflammatory scores [DII, two energy-adjus
The impact of CO dilution on combustion of syngas (a mixture of H2, CO, and CH4) was investigated in a lab-scale gas turbine model combustor at atmospheric pressure conditions. Two mild dilution levels of CO2, corresponding to 15% and 34% of CO2 mole fraction in the syngas/CO2 mixtures, were experimentally investigated to evaluate the effects of CO2 dilution on the flame structures and the emissio
Cognitive screening has been proposed for older adults diagnosed with chronic obstructive pulmonary disease (COPD). Therefore, we examined the change over time in cognitive function and the risk of incident dementia in older adults after COPD diagnosis. A sample of 3,982 participants from the population-based cohort study Good Aging in Skåne was followed for 19 years, and 317 incident COPD cases w
Evidence of the effectiveness of the tests used to diagnose Helicobacter pylori (H. pylori) in primary healthcare is limited. This cross-sectional study aims to assess the accuracy of tests used for to diagnose H. pylori infection in primary care patients and its relationship with gastroduodenal pathologies. Over 12 months, 173 primary care patients with dyspeptic symptoms were referred for upper
Background & aims: Tissue transglutaminase autoantibodies (tTGA) are used as diagnostic markers of celiac disease. Different methods have been developed for the detection of tTGA of which enzyme-linked immunosorbent assays (ELISA), radiobinding assays (RBA) and electrochemiluminescence (ECL) assays are the most commonly used. Here we aimed to evaluate a novel antibody detection by agglutinatio
