Comparison of ROS production of individual particle components from traffic-related sources can inform new health policies and emissions legislation. This work aims to quantify acellular ROS production and oxidative potential (OP) of such individual particle components from combustion, brake, tire, and road wear. Particle characteristics are probed to identify source-specific markers and improve t
The gut microbiota is associated with human health and disease. Here we conducted a genome-wide association study of host genetic factors influencing gut microbiota composition in 12,652 individuals from the Trøndelag Health Study (HUNT), with replication in Nordic cohorts (n = 16,017–21,976). We identified 12 reproducible SNP–species associations across six genomic loci, including known (LCT, ABO
Background SLE is a systemic autoimmune disease with a large number of common risk gene variants, but several rare gene variants can cause monogenic SLE. The relationship between common and rare variants in SLE is unclear. We therefore investigated the occurrence of rare deleterious variants in patients with childhood-onset SLE (cSLE) and adult-onset SLE (aSLE) and compared the frequency of these
This thesis investigates particle sorting in deterministic lateral displacement (DLD) microfluidic devices, with a focus on how particle size and shape influence sorting behavior. A broad range of synthetic and biological particles were studied, including polystyrene particles, fabricated silicon-based structures, and bacterial samples with diverse physical properties.While DLD has traditionally b
Disruptions in gut microbiome are implicated in cardiometabolic disorders and other health outcomes. Antibiotics are known gut microbiome disruptors, but their long-term consequences remain underexplored. Here we combined individual-level data from the Swedish Prescribed Drug Register with fecal metagenomes of 14,979 adults to examine the association between oral antibiotic use over 8 years and gu
Objective To compare longitudinal speech outcomes at ages 5 and 10 years in foreign-born and Swedish-born children with cleft palate with or without cleft lip (CP ± L), and assess impact of cleft type, additional diagnosed conditions, sex, and age at completed primary palatal surgery.DesignLongitudinal, registry-based cohort study.SettingRegional public care university hospitals in Sweden.Particip
The metastatic potential of cancer cells is closely linked to their mechanical properties, and changes in these properties often correspond to the progression of the disease. To study how mechanical factors such as cell size and deformability influence the spread of cancer and the surrounding extracellular matrix, it is crucial that cancer cell populations be sorted in relevant subpopulations with
Background: Severe Alpha-1-Antitrypsin deficiency (AATD), phenotype PiZZ, is a leading cause of liver disease in neonates, children, and adults. Nevertheless, the prevalence of liver disease and mortality within PiZZ adults remains unclear. Between 1972 and 1974, a cohort of 129 individuals with severe AATD (PiZZ) was identified through the Swedish national screening of 200,000 newborns. The cohor
Metabolic syndrome (MetS) is a cluster of cardiovascular risk factors, including abdominal obesity, insulin resistance, dyslipidemia, and hypertension. Its association with venous thromboembolism (VTE) has been inconsistently reported. We investigated the association between MetS and VTE, and the influence of sex and abdominal obesity. We included 12,788 middle-aged and older adults from the re-ex
The formation of InSb quantum dots (QDs) embedded in an InAs matrix grown by molecular beam epitaxy (MBE) was studied parametrically. In particular, the effect of the sequence of the change of As2 dimers and Sb2 on the distribution of As and Sb at the InSb-QDs/InAs interface was investigated by cross-sectional transmission electron microscopy (TEM). It was shown that additional As2 above the InSb
Optimization and electrical control of photovoltaic (PV) and proton exchange membrane (PEM) electrolyzer systems are critical for efficient, scalable hydrogen production. Static coupling methods employ fixed electrical interconnections between PV arrays and the PEM stack, which cannot adapt to fluctuating irradiance or temperature. To overcome this, we propose an adaptive reconfiguration optimizat
Background: Microseminoprotein-beta (MSP), a protein secreted by the prostate epithelium, may have a protective role in the development of prostate cancer. The only previous prospective study found a 2% reduced prostate cancer risk per unit increase in MSP. This work investigates the association of MSP with prostate cancer risk using observational and Mendelian randomization (MR) methods. Patients
Background: Earlier age at menopause has been associated with increased risk of coronary heart disease (CHD), but the shape of association and role of established cardiovascular risk factors remain unclear. Therefore, we examined the associations between menopausal characteristics and CHD risk; the shape of the association between age at menopause and CHD risk; and the extent to which these associ
Selenoprotein-P (SELENOP) is the main carrier of selenium to target organs and reduces tissue oxidative stress both directly and by delivering selenium to protective selenoproteins. We tested if the plasma concentration of SELENOP predicts cardiovascular morbidity and mortality in the primary preventive setting. SELENOP was measured from the baseline exam in 2002–2006 of the Malmö Preventive Proje
In 2014, a new initiative was undertaken by groups working on plans for the transplantation of stem-cell-based derived dopaminergic neurons for treating Parkinson’s disease patients. This GForce-PD group held its annual meeting on 18–19 April 2016 in Chicago at Rush University to discuss their progress and the challenges that the translation of this experimental therapy still faces. Over 2 days, t
Background: Certain immunoglobulins (Ig) are proposed to have protective functions in atherosclerosis.Objectives: We tested whether serum levels of IgG and IgM autoantibodies against malondialdehyde low density lipoprotein (MDA-LDL) are associated with clinical coronary heart disease (CHD) and unfavorable plaque characteristics.Methods: NORDIL was a prospective study investigating adverse cardiova
Recent research suggests an important role of the meniscus in the development of knee osteoarthritis. We, therefore, aimed to analyze the proteome of the normal human meniscus body, and specifically to gain new knowledge on global protein expression in the different radial zones. Medial menisci were retrieved from the right knees of 10 human cadaveric donors, from which we cut a 2 mm radial slice
Background: Patient enrolment into clinical trials is based on oral information and informed consent, which includes an information sheet and a consent certificate. The written information should be complete, but at the same time risks being so complex that it may be questioned if a fully informed consent is possible to provide. We explored patient representatives' views and perceptions on the wri
Aims A higher intake of fruits and vegetables has been associated with a lower risk of ischaemic heart disease (IHD), but there is some uncertainty about the interpretation of this association. The objective was to assess the relation between fruit and vegetable intake and risk of mortality from IHD in the European Prospective Investigation into Cancer and Nutrition (EPIC)-Heart study. Methods and
