In a middle-aged population, it was recently shown that the stable vasopressin marker plasma copeptin (copeptin) predicts development of diabetes mellitus, diabetic heart disease and death. Here, it was hypothesised whether copeptin predicts a risk of coronary artery disease (CAD), and cardiovascular mortality in an older population.
It has become increasingly clear that several age-associated pathologies associate with mutations in the mitochondrial genome. Experimental modeling of such events has revealed that acquisition of mitochondrial DNA (mtDNA) damage can impair respiratory function and, as a consequence, can lead to widespread decline in cellular function. This includes premature aging syndromes. By taking advantage o
In the field of developmental biology, there is compelling evidence for a network of activity of pluripotency and stem-associated genes comprising of Oct4, Nanog and nestin. During neurogenesis, the choice between enhancement versus suppression of transcriptional modulation of these identified genes determines the balance between self-renewal neural stem cells (NSC) and immature neuronal phenotype
Oxygen-enhanced MRI (OE-MRI) biomarkers have potential value in assessment of COPD, but need further evaluation before treatment-induced changes can be interpreted. The objective was to evaluate how OE-MRI parameters of regional ventilation and oxygen uptake respond to standard pharmacological interventions in COPD, and how the response compares to that of gold standard pulmonary function tests.
Despite 3 decades of basic and clinical studies, there is still no dopaminergic cell therapy for Parkinson's disease. Several arguments have been put forward why this approach, so far tested with transplantation of human fetal mesencephalic dopamine-rich tissue, will never be of clinical use and should be abandoned: (1) Lack of efficacy in 2 sham surgery-controlled trials; (2) occurrence of troubl
Background: A growing number of individuals are diagnosed with hereditary cancer. Though increased levels of anxiety and depression have been demonstrated around the time of genetic counselling, most individuals handle life at increased risk well. Data have, however, been collected on individual basis, which led us to focus on family perspectives of hereditary cancer. Methods: Lynch syndrome repre
Abstract For nanotoxicology investigations of air-borne particles to provide relevant results it is ever so important that the particle exposure of, for example cells, closely resembles the "real" exposure situation, that the dosimetry is well defined, and that the characteristics of the deposited nanoparticles are known in detail. By synthesizing the particles in the gas-phase and directly deposi
The DIRECT (Diabetes Research on Patient Stratification) Study is part of a European Union Framework 7 Innovative Medicines Initiative project, a joint undertaking between four industry and 21 academic partners throughout Europe. The Consortium aims to discover and validate biomarkers that: (1) predict the rate of glycaemic deterioration before and after type 2 diabetes onset; (2) predict the resp
Aims Aortic valve calcification (AVC) is an underlying pathophysiological mechanism for aortic stenosis that is common in the elderly, but less is known in younger individuals. The aim was to study the prevalence and associated characteristics of AVC in a middle-aged general population. Methods and results Data were obtained from the Swedish CArdioPulmonary bioImage Study (SCAPIS) comprising 30 15
Rare earth elements (lanthanides) are critical materials for many applications, particularly those involved in new energy. Extracting these elements economically from low-concentration sources may be challenging. This study investigates the interaction of Ce and Gd with microalgae that have been triggered to form phosphate-rich granules. Lanthanides usually occur in nature as phosphates, and there
When exposed to high levels of phosphate after experiencing phosphate deficiency, microalgae can synthesize granules rich in intracellular phosphate. The understanding of the mechanism of production and nature of these granules remains incomplete. Here we studied phosphate distribution and chemistry in Chlamydomonas reinhardtii and Desmodesmus armatus using scanning transmission X-ray microscopy (
Early kidney function decline may be associated with reduced filtration of middle-sized molecules, currently defined as selective glomerular hypofiltration syndrome (SGHS), and driven by the accumulation of atherosclerosis-promoting proteins. We aimed to investigate whether SGHS and other markers of kidney function are associated with subclinical atherosclerosis as evaluated by intima-media thickn
Background: Women who have undergone cervical conization may still experience subsequent pregnancies and delivery. However, it remains unknown whether pregnancy, associated with immune tolerance, might increase the risk of subsequent cervical lesions. This study aims to address this knowledge gap by utilizing the nationwide Swedish registers. Methods: A total of 60,895 women diagnosed with cervica
Background: Low-cost particulate matter sensors have enabled new opportunities for exposure monitoring but require evaluation before application in epidemiological studies. This study assessed the performance of the SPS30 sensor integrated into the ARMIE portable monitoring sensor-node under controlled laboratory conditions. Methods: Sensors were co-located with two comparison instruments—the opti
Background: Human immunodeficiency virus type 1 (HIV-1) is one of the fastest-evolving human pathogens. Understanding HIV-1 transmission, within-host adaptation, and evolutionary dynamics is pivotal for development of interventions and vaccines. HIV-1 infection is generally caused by a single transmitted founder virus (TFV), and TFV sequences are typically obtained using single genome amplificatio
The process that generates the different types of highly differentiated cells in the immune system from hematopoietic stem cells involves not only the acquisition of lineage-specific features, but also the permanent repression of alternative developmental programs and the preservation of lineage identity. The well-charted developmental trajectory of early B-cell development, in combination with ab
Cystitis is a bacterial infection of the bladder that occurs in about half of women at least once in their lifetime. Antibiotics such as nitrofurantoin are used to treat cystitis, but antibiotic resistance is a concern, especially for recurrent infections. Here we report an open-label, randomized, single-centre, phase 2 study to analyse the acute and long-term safety and efficacy of the IL-1 recep
Objective: Prior to in vitro fertilization (IVF), physicians can choose either recombinant or urine-derived follicle-stimulating hormone (FSH) for ovarian stimulation. The common polymorphism N680S (rs6166) in the follicle-stimulating hormone receptor (FSHR) has been linked to individual variability in ovarian response to FSH stimulation and IVF outcomes, including live birth rates, highlighting i
