Glial progenitor cells are widely distributed in brain parenchyma and represent a suitable target for future therapeutic interventions that generate new neurons via in situ reprogramming. Previous studies have shown successful reprogramming of mouse glia into neurons whereas the conversion of human glial cells remains challenging due to the limited accessibility of human brain tissue. Here, we hav
Objective: To develop and perform ex vivo 3D imaging of meniscus posterior horn microstructure using micro-computed tomography (μCT), and to compare specimens from healthy references against end-stage osteoarthritis (OA) using conventional section-based histology and qualitative μCT. Design: We retrieved human medial and lateral menisci from 10 deceased donors without knee OA (healthy references)
Purpose: A cost minimisation analysis compares the costs of different interventions’ to ascertain the least expensive over time. We compared different prostate targeted drug treatments with TURP to identify the optimal cost saving duration of a medical therapy for symptomatic benign prostatic enlargement (BPE). Methods: The Evolution registry is a prospective, multicentre registry, conducted by th
Few prospective studies have examined the factor V paradox: factor V Leiden (FVL) is a stronger risk factor for deep venous thrombosis (DVT) than for pulmonary embolism (PE). The present study, to the best of our knowledge, is the first population-based study aimed to examine the relationship between FVL and incidence of venous thromboembolism (VTE), DVT and PE in a prospective cohort study of mid
Current evidence on congenital malformations in the offspring of cancer survivors is largely inconsistent. Therefore, through this study we aimed to explore the prevalence of congenital malformations in the offspring of cancer survivors. To this end, female cancer survivors were identified from the Swedish Cancer Register and were further linked to the Swedish Medical Birth Register and Hospital D
A personal history of autoimmune diseases is associated with an increased incidence of gastric cancer, but whether they share familial susceptibility is still unknown. The contribution of shared environmental or genetic factors toward the observed familial aggregation has not been determined. We used a few Swedish registers, including the Swedish Multigeneration Register and the Cancer Register, t
Aim: Investigate the feasibility of identifying a well-defined treatment group and a comparable reference group in clinical register data. Background: There is insufficient knowledge on how to avert neck/back pain from turning chronic or to impair work ability. The Swedish Government implemented a national multimodal rehabilitation (MMR) programme in primary care intending to promote work ability,
We have recently completed the largest GWAS on lung cancer including 29,266 cases and 56,450 controls of European descent. The goal of our study has been to integrate the complete GWAS results with a large-scale expression quantitative trait loci (eQTL) mapping study in human lung tissues (n = 1,038) to identify candidate causal genes for lung cancer. We performed transcriptome-wide association st
BACKGROUND: Obesity is an established risk factor for several cancers. Adult weight gain has been associated with increased cancer risk, but studies on timing and duration of adult weight gain are relatively scarce. We examined the impact of BMI (body mass index) and weight changes over time, as well as the timing and duration of excess weight, on obesity- and non-obesity-related cancers. METHODS:
Chronic kidney disease (CKD) is responsible for a public health burden with multi-systemic complications. Through trans-ancestry meta-analysis of genome-wide association studies of estimated glomerular filtration rate (eGFR) and independent replication (n = 1,046,070), we identified 264 associated loci (166 new). Of these, 147 were likely to be relevant for kidney function on the basis of associat
BACKGROUND & AIMS: Phosphodiesterase 5 (PDE5) inhibitors have been proposed to have chemopreventative effects on colorectal cancer (CRC), although data are needed from population-based studies. We performed a nationwide cohort study to investigate the association between use of PDE5 inhibitors and risk of CRC in men with benign colorectal neoplasms.METHODS: We identified men who received a dia
The classification and monitoring of individuals with early knee osteoarthritis (OA) are important considerations for the design and evaluation of therapeutic interventions and require the identification of appropriate outcome measures. Potential outcome domains to assess for early OA include patient-reported outcomes (such as pain, function and quality of life), features of clinical examination (
The presence of amyloid fibrils of α-synuclein is closely associated with Parkinson's disease and related synucleinopathies. It is still very challenging, however, to systematically discover small molecules that prevent the formation of these aberrant aggregates. Here, we describe a structure-based approach to identify small molecules that specifically inhibit the surface-catalyzed secondary nucle
A general discovery in protein science in the past few decades has been the finding that a number of unrelated proteins and peptides all have a marked propensity to form amyloid fibrils in vivo and in vitro. These structures have become known as the pathological hallmark of some of the most prevalent neurodegenerative diseases. More recently, the process of amyloid formation has been demystified t
Metal-halide perovskites (MHPs) are promising as active optoelectronic materials for a diverse range of devices. Anion exchange is a post-growth modification of MHP materials that allows tuning of the band gap and crystal structure by exposure to alternative halides, normally using solution methods. Here, low temperature gas-phase anion exchange for the conversion of CsPbBr3 nanowires (NW) into Cs
Light microscopy has been a favorite tool of biological studies for almost a century, recently producing detailed images with exquisite molecular specificity achieving spatial resolution at nanoscale. However, light microscopy is insufficient to provide chemical information as a standalone technique. An increasing amount of evidence demonstrates that optical photothermal infrared microspectroscopy
The MEDIM study reports that Immigrants from the Middle East to Sweden – independently of other diabetes related risk factors – have a twice as high type 2 diabetes risk as compared to non-immigrated Swedes. Diabetes onset occurs 6 years earlier in this group and is partly explained by family history and/or obesity. But the MEDIM study has identified that Middle Eastern background per se is an ind
Astrocytes are one of the major cell types in the central nervous system and are indispensable for brain development and function. The human brain and human astrocytes have unique structures and functions that are not present in other animal species. Studies of fundamental astrocyte biology in humans and their role in neurological disease have been hindered by shortage of native human astrocytes f
