Dynamic epigenetic age mosaicism in the human atherosclerotic artery

Accelerated epigenetic ageing, a promising marker of disease risk, has been detected in peripheral blood cells of atherosclerotic patients, but evidence in the vascular wall is lacking. Understanding the trends of epigenetic ageing in the atheroma may provide insights into mechanisms of atherogenesis or identify targets for molecular therapy. We surveyed DNA methylation age in two human artery sam

Astrocytic function is associated with both amyloid-β and tau pathology in non-demented APOE 4 carriers

A growing body of evidence suggests that astrocytes play a major role in the pathophysiology of Alzheimer's disease. Given that APOE is primarily expressed in astrocytes, these cells might be an important link between the APOE ϵ4 allele and the development of Alzheimer's disease pathology. Here, we investigate this hypothesis in vivo by measuring myo-inositol, a metabolite involved in astrocytic f

CD244 expression represents functional decline of murine hematopoietic stem cells after in vitro culture

Isolation of long-term hematopoietic stem cell (HSC) is possible by utilizing flow cytometry with multiple cell surface markers. However, those cell surface phenotypes do not represent functional HSCs after in vitro culture. Here we show that cultured HSCs express mast cell-related genes including Cd244. After in vitro culture, phenotypic HSCs were divided into CD244- and CD244+ subpopulations, an

The race to publish results during the outbreak of the new coronavirus (SARS-CoV-2) has highlighted the relevance of sharing data and research results more quickly and openly than the current scientific communication system, as well as the role of social media in this context. This paper aims to analyze the impact of open access on the production and dissemination of knowledge about COVID-19 in tr

Prediction of surface water turnover time in coastal waters using digital bathymetric information

This paper presents a new type of geographical information system (GIS) for scientific planning of coastal waters. One hypothesis in the work is that the morphometry of the coast plays a significant role for how the water system functions as a receiving water system, for example, as a receiver of industrial and urban pollution and in response to various forms of aquaculture. A digital technique fo

HMGA1 has predictive value in response to chemotherapy in gastric cancer

Gastric cancer is a serious health problem worldwide. Although its incidence is decreasing, the five-year survival rate remains low. Thus, it is essential to identify new biomarkers that could promote better diagnosis and treatment of patients with gastric cancer. High-mobility group AT-hook 1 (HMGA1) is a non-histone, chromatin-binding protein that has been found overexpressed in several tumor ty

Development of optical diagnostics of plasma-related phenomena and applications

Optical diagnostics techniques based on coded imaging were developed and applied for plasma-related phenomena and applications. The signal of interest is first encoded with a sinusoid pattern either by structured laser illumination or implement of a diffractive optical element, such as a grating, along the optical path of the signal. The coded signal will then be extracted from the raw data by a l

Distance Creates Distance: Preschool Staff Reflections and Experiences Concerning Preschool Introduction During the Covid-19-Pandemic

Recent attachment research attests that children’s relationships to preschool staff can contribute to their attachment development. The preschool introduction phase constitutes a natural arena for establishing these relationships, so organizing this introduction to enable relation-building between staff and children is essential. In Sweden, preschools stayed open during the covid-19-pandemic, howe

Imaging biomarkers in animal models of drug-induced lung injury : A systematic review

For drug-induced interstitial lung disease (DIILD) translational imaging biomarkers are needed to improve detection and management of lung injury and drug-toxicity. Literature was reviewed on animal models in which in vivo imaging was used to detect and assess lung lesions that resembled pathological changes found in DIILD, such as inflammation and fibrosis. A systematic search was carried out usi

Predicting intensive care need in women with preeclampsia using machine learning–a pilot study

Background: Predicting severe preeclampsia with need for intensive care is challenging. To better predict high-risk pregnancies to prevent adverse outcomes such as eclampsia is still an unmet need worldwide. In this study we aimed to develop a prediction model for severe outcomes using routine biomarkers and clinical characteristics. Methods: We used machine learning models based on data from an i

Seizure freedom but not epilepsy surgery is associated with fewer neuropsychiatric difficulties in patients with tuberous sclerosis

BACKGROUND: Drug-resistant epilepsy (DRE) in selected individuals with the rare tuberous sclerosis complex (TSC) may benefit from resective epilepsy surgery. Furthermore, associated neuropsychiatric disorders (TAND) are common in patients with TSC; however, long-term data on how surgery affects neuropsychiatric comorbidities are sparse.MATERIALS AND METHODS: Two retrospective approaches were used

Beyond environmental harm : Industry claims, lived experiences, and the impacts of gas extraction

The peer-reviewed literature presents overwhelming evidence that fossil fuel based energy infrastructure projects are responsible for lower residential property values, environmental destruction and pollution that decrease residents' quality of life. These projects also challenge local people's sense of identity and even the threat of such a project can make residents question their sense of place

Associations of Subjective Sleep Quality with Wearable Device-Derived Resting Heart Rate During REM Sleep and Non-REM Sleep in a Cohort of Japanese Office Workers

Background: Associations between subjective sleep quality and stage-specific heart rate (HR) may have important clinical relevance when aiming to optimize sleep and overall health. The majority of previously studies have been performed during short periods under laboratory-based conditions. The aim of this study was to investigate the associations of subjective sleep quality with heart rate during

On Calibration Algorithms for Real-Time Brain-Computer Interfaces

A Brain-Computer Interface (BCI) is a system that, in real-time, translates the user's brain activity into commands that can be used to control applications, such as moving a cursor on the screen. The translation is made possible by machine learning methods and other algorithms. The thesis focuses on EEG-based BCIs which are the most common type of BCIs due to EEG measurements being non-invasive,

Evaluation of the applicability of GARDskin to predict skin sensitizers in extracts from medical device materials

Biocompatibility testing of medical devices is governed by the ISO 10993 series of standards and includes evaluation of skin sensitization potential of the final product. A majority of all medical devices are tested using in vivo methods, largely due to the lack of in vitro methods validated within the applicability domain of solid materials. The GARDskin method for assessment of chemical skin sen

Optimized procedure for high-throughput transcriptome profiling of small extracellular vesicles isolated from low volume serum samples

OBJECTIVES: Small extracellular vesicles (EVs) contain various signaling molecules, thus playing a crucial role in cell-to-cell communication and emerging as a promising source of biomarkers. However, the lack of standardized procedures impedes their translation to clinical practice. Thus, we compared different approaches for high-throughput analysis of small EVs transcriptome.METHODS: Small EVs w

The Impact of Switch Faults on Train Delays : A Case Study of the Swedish Railway Network

Switches and crossings are prone to failure thus making them drivers of unreliability in the operation of many railway systems. Unreliability is directly linked to punctuality which continues to limit, among other factors, the uptake of railways as a sustainable mode of transport. To fix this issue, there is a need for a better understanding of the contribution of railway sub-systems to train dela

The Law of Riba in Islamic Banking : Conventional and Unconventional Approaches to Interest-Free Financing

The issue of riba, that is, interest/the “excess” or “surplus” on loans is crucial for both Islamic and non-Islamic countries. Western economic systems use interest to distribute financial resources efficiently for investment and/or consumption, while Islamic economies pursue a completely different strategy for financing loans, which adheres to Islamic laws and prohibits the activities of conventi

Disablised or Ablised?: Linguistic Categorisations of Dis/ability in Swedish Print Media Over Time

Which linguistic labels we use to name ourselves and others – such as disabled and non-disabled – make a difference regarding how we see ourselves and each other. Such labels may also say something about how we view society and the roles of people in it, as illustrated by the choice between people-first and identity-first labels. In the present study, we use a sample of 56,666 articles published b
