We present a numerical model for the recently introduced simple and inexpensive micromachined aluminum devices with a polydimethylsiloxane (PDMS) cover for microparticle acoustophoresis. We validate the model experimentally for a basic design, where a microchannel is milled into the surface of an aluminum substrate, sealed with a PDMS cover, and driven at MHz frequencies by a piezoelectric lead-zi
Background: Saturated fat (SFA) has consistently been shown to increase liver fat, but the response appears variable at the individual level. Phenotypic and genotypic characteristics have been demonstrated to modify the hypercholesterolemic effect of SFA but it is unclear which characteristics that predict liver fat accumulation in response to a hypercaloric diet high in SFA. Objective: To identif
The CRISPR/Cas9 system is a versatile tool for functional genomics and forward genetic screens in mammalian cells. However, it has been challenging to deliver the CRISPR components to sensitive cell types, such as primary human hematopoietic stem and progenitor cells (HSPCs), partly due to lentiviral transduction of Cas9 being extremely inefficient in these cells. Here, to overcome these hurdles,
Background: In any study with voluntary participation, self-selection risks leading to invalid conclusions. If the determinants of selection are observed, it is however possible to restore the parameters of interest by reweighting the sample to match the population, but this approach has seldom been applied in epidemiological research. Methods: We reweighted the Malmö Diet and Cancer (MDC) study b
The disease COVID-19 has developed into a worldwide pandemic. Hyperinflammation and high levels of several cytokines, for example, IL-6, are observed in severe COVID-19 cases. However, little is known about the cellular origin of these cytokines. Here, we investigated whether circulating leukocytes from patients with COVID-19 had spontaneous cytokine production. Patients with hyperinflammatory COV
We investigated causal effect of completed growth, measured by adult height, on coronary heart disease (CHD), stroke and cardiovascular traits, using instrumental variable (IV) Mendelian randomization meta-analysis.
OBJECTIVE: Polymorphonuclear leukocytes (PMN) with autoantibody-coated engulfed necrotic cell material (NC) are frequently seen in systemic lupus erythematosus (SLE). We evaluated the roles of complement, different antihistone antibodies (anti-H ab), and oxidative burst in the phagocytosis of NC by PMN, as well as association to disease activity and clinical phenotype in SLE. METHODS: ELISA an
Bone area is one measure of bone size that is easily derived from dual-energy X-ray absorptiometry (DXA) scans. In a GWA study of DXA bone area of the hip and lumbar spine (N ≥ 28,954), we find thirteen independent association signals at twelve loci that replicate in samples of European and East Asian descent (N = 13,608 – 21,277). Eight DXA area loci associate with osteoarthritis, including rs14
The PNPLA3 I148M variant is the major genetic risk factor for all stages of fatty liver disease, but the underlying pathophysiology remains unclear. We studied the effect of this variant on hepatic metabolism in homozygous carriers and non-carriers under multiple physiological conditions with state-of-the-art stable isotope techniques. After an overnight fast, carriers had higher plasma β-hydroxyb
Aims: The main aim of the present study was to identify factors influencing health-related quality of life (HRQoL), as measured by EQ-5D-5L, in individuals 1 year after the acute phase of COVID-19.Methods: This cross-sectional study included 75 participants (51% females), 1 year after confirmed SARS-CoV-2 infection (76% hospitalised). Associations between HRQoL, measured by patient-reported outcom
In architecture and urban geography, discussions on repair, maintenance and adap5ve re-usehave emerged as a crucial intellectual terrain. Temporal aspects of how the urban fabric isused have also emerged as an issue worth theore5cal and empirical a=en5on. Latching ontothese themes, we will present work tracking the history of conten5on around the publiclyowned mee5ng and arts venue in Lund’s Peopl
Cardiovascular disease is the global number one causeof mortality and morbidity. The majority of cardio vascular diseases are caused by atherosclerosis, a lipid-driven, inflammatory disease of the middle- and large-sized arteries. The disease is characterized by the formation of atherosclerotic plaques throughout the arterial tree. Over the years, insights intohe pathogenesis of atherosclerosis ha
Background: Nocturnal gastro-oesophageal reflux (nGER) is common in people with respiratory diseases, but its association with pulmonary abnormalities is not known. Aim: Investigate the association between nGER and pulmonary abnormalities on chest CT in an adult general population. Methods: In total, 28 846 individuals from the general population aged 50-64 years completed questionnaires and under
A concept of germ graphs and the M-function formalism are employed to construct large families of isospectral and isoscattering graphs. This approach represents a complete departure from the original approach pioneered by Sunada, where isospectral graphs are obtained as quotients of a certain large symmetric graph. Using the M-function formalism and the symmetries of the graph itself we construct
Precision oncology is being transformed by the integration of advanced machine learning (ML) methods and extensive biomedical data from genomics, imaging, proteomics, and clinical records. ML techniques, including supervised, unsupervised, deep learning, and reinforcement learning, have progressed from experimental tools to robust systems that identify clinically actionable biomarkers, refine prog
This chapter reviews the growing body of epidemiological evidence linking long-term exposure to ambient air pollution with increased risk of dementia, including Alzheimer’s disease (AD) and vascular dementia (VaD). With air pollution now recognized as a potentially modifiable risk factor, the chapter explores mechanistic pathways, such as neuroinflammation and oxidative stress, through which pollu
Introduction Autistic persons experience problems with movements and body awareness in everyday functionality, expressed in affected movement quality. Yet, there is a knowledge gap about the effects of interventions targeting these aspects in autistic persons. Objective To evaluate effects of Basic Body Awareness Therapy (BBAT) and treatment-as-usual (TAU), compared to TAU alone on movement qualit
Successful translation requires multiple protein factors with diverse specific activities. Initiation of translation is regarded as the most tightly regulated step of this process, controlled by numerous factors. Among these is the eukaryotic initiation factor 4F (eIF4F), a protein complex composed of three subunits: the cap-binding protein eIF4E, the RNA helicase eIF4A, and the scaffolding protei
Polyunsaturated fatty acids (PUFA) have been shown to reduce liver fat compared to saturated fat, but effects of a novel “anti-lipogenic” diet replacing carbohydrates with PUFA (LCPUFA) or a low-fat healthy Nordic diet (HND) rich in whole-grains are unknown. The objective of this study was to investigate the effects of these diets, as compared with usual care (UC), on liver fat (primary outcome) a
