Nitrogenase is the only enzyme that can cleave the strong triple bond inN2. The active site contains a complicated MoFe7S9C cluster. It is believed that itneeds to accept four protons and electrons, forming the E4 state, before it can bind N2.However, there is no consensus on the atomic structure of the E4 state. Experimentalstudies indicate that it should contain two hydride ions bridging two pai
Objective: Early decrease in fetal haemoglobin (HbF) is an indicator of loss of endogenous blood components that might have predictive value for development of bronchopulmonary dysplasia (BPD). The link between HbF and BPD has not been evaluated. Design: Retrospective observational study. Setting: Tertiary level neonatal intensive care unit, referral centre for Southern Sweden. Patients: 452 very
Objective As part of European League against Rheumatism (EULAR)/European Musculoskeletal Conditions Surveillance and Information Network, 20 user-focused standards of care (SoCs) for rheumatoid arthritis (RA) addressing 16 domains of care were developed. This study aimed to explore gaps in implementation of these SoCs across Europe. Methods Two cross-sectional surveys on the importance, level of a
The first aim of this study was to on historical background survey women's alcohol habits and especially to investigate women aged 50-59 living in the Lund area. The second aim was to increase the understanding of how women's sex role has a restrictive influence on their alcohol habits. To investigate women's alcohol habits I made two quantitative studies. From secondary data I found t
Thesis Purpose: This study aims to enhance the understanding of factors that discourage consumers from buying pre-owned fashion in a multichannel retail setting. Methodology: Rooted in a qualitative and exploratory method, this study is further guided by an abductive approach. By embracing the essence of the social constructivist epistemology and a relativistic ontological standpoint, it delves i
The first measurement of the e+e− pair production at midrapidity and low invariant mass in central Pb-Pb collisions at √sNN = 5.02 TeV at the Large Hadron Collider is presented. The yield of e+e− pairs is compared with a cocktail of expected hadronic decay contributions in the invariant mass (mee) and pair transverse momentum (pT,ee) ranges mee < 3.5 GeV/c2 and pT,ee < 8 GeV/c. For 0.18 < mee < 0.
Background. Seeking to clarify the parent-offspring transmission of Major Depression (MD) and type I Bipolar Disorder (BD), we examined offspring MD and BD risk in five informative parental pairs: Unaffected x MD, Unaffected x BD, MDxMD, MDxBD and BDxBD. Methods. We identified 289,637 individuals born in Sweden 1970-1990, followed through 2018, from parents with MD and/or BD identified from Swedis
Background: Black carbon (BC) is an air pollutant of growing concern due to its adverse impacts on health and climate. Growing evidence suggests that BC could have a number of negative impacts on morbidity and mortality, but more evidence is needed. Objective: The objectives of this study are to quantify any associations between BC exposure and cause-specific (cardiovascular and cancer) mortality
Introduction – Hand-arm vibration syndrome (HAVS) is a chronic disease to vessels and nerves caused by vibrations. In Sweden, the medical check-up for vibrations (MCV) implements the EU surveillance system to detect early cases. No earlier research has shown participation in MCVs, nor why MCVs is avoided. We aimed to improve the understanding on avoidance of MCVs among vibration-exposed workers. M
INTRODUCTION: Cognitive impairment is common in parkinsonian disorders, but its extent among older adults with subtle motor abnormalities without a diagnosed movement disorder remains unclear. We examined cognitive decline, domain-specific cognitive function and incident dementia in older adults with subthreshold parkinsonism and parkinsonism (primary analysis). Sensitivity analyses were repeated
Introduction: Cytostatic pharmaceuticals are increasingly detected in the aquatic environment, raising concerns due to their persistence and toxicity. Background: Conventional wastewater treatment processes do not effectively remove these compounds. Advanced oxidation processes, such as ozonation, are needed to degrade cytostatic pharmaceuticals during wastewater treatment. However, these process
Introduction: Omega-3 fatty acid supplements are widely used as an alternative to eating oily fish. However the polyunsaturated oils they contain are highly susceptible to oxidation, which can lead to rancidity and possibly decreased quality of the supplement. Background: Despite the convenience of omega-3 supplementation, there is limited independent information on the oxidative quality of produ
The aim of the study was to investigate whether work-study conflict and study-work conflict predict perceived stress and well-being in full-time university students who work part-time, and whether perceived stress predicts well-being. The study was conducted with a quantitative cross-sectional design where data were collected through a web-based questionnaire where participants answered establishe
Objectives To assess the performance of the ALL IN TRIPLEX rapid antigen-based test for SARS-CoV-2, influenza A, influenza B, and respiratory syncytial virus. We focus on the potential of the test to be used in acute clinical settings as a marker of infectiousness, by determining the sensitivity at different real-time PCR cycle threshold (Ct) levels, as well as the quantity of absorbed viral RNA n
Background: Mistletoe extract is a widespread complementary therapy mainly used for quality-of-life improvement in cancer patients. Advanced pancreatic cancer is associated with poor quality of life and better therapies for symptomatic relief are highly needed. Aim: MISTRAL aimed to assess the impact of mistletoe extract on quality of life, body weight, observed costs and blood biomarkers in patie
Mitochondrial dysfunction is associated with pathogenic mitochondrial (mt)DNA mutations. The majority of mtDNA point mutations have a heteroplasmic status, which is defined as the coexistence of wild-type and mutated DNA within a cell or tissue. Previous findings demonstrated that certain mtDNA heteroplasmic mutations contribute to widely spread chronic diseases, including cancer, and alterations
AIMS: Previous studies show inconsistencies in vasovagal syncope (VVS) symptoms and haemodynamic responses across age and sex groups, with limited evaluation of tilt test results. This study comprehensively examines differences in triggers, prodromal and syncopal symptoms, and head-up tilt test (HUTT) responses among VVS patients by age and sex providing new insights.METHODS AND RESULTS: We analys
