MAFA and MAFB regulate exocytosis-related genes in human β-cells

AIMS: Reduced expression of exocytotic genes is associated with functional defects in insulin exocytosis contributing to impaired insulin secretion and type 2 diabetes (T2D) development. MAFA and MAFB transcription factors regulate β-cell physiology, and their gene expression is reduced in T2D β cells. We investigate if loss of MAFA and MAFB in human β cells contributes to T2D progression by regul

Lipid-Associated Variants near ANGPTL3 and LPL Show Parent-of-Origin Specific Effects on Blood Lipid Levels and Obesity

Parent-of-origin effects (POE) and sex-specific parental effects have been reported for plasma lipid levels, and a strong relationship exists between dyslipidemia and obesity. We aim to explore whether genetic variants previously reported to have an association to lipid traits also show POE on blood lipid levels and obesity. Families from the Botnia cohort and the Hungarian Transdanubian Biobank (

How paediatric departments in Sweden facilitate giving children a voice on their experiences of healthcare : A cross-sectional study

Background: In January 2020, the United Nations Convention on the Rights of the Child was incorporated into Swedish law. According to Swedish regulations, patients are to be given the opportunity to participate in quality improvement. Sometimes, the patients are children who have the right to be heard on matters concerning them, such as their experience of a hospital visit. Objective: This study a

Comparison of the predictive value of two international guidelines for safe discharge of patients with mild traumatic brain injuries and associated intracranial pathology

Purpose: To determine and compare the sensitivity, specificity, and proportion of patients eligible for discharge by the Brain Injury Guidelines and the Mild TBI Risk Score in patients with mild traumatic brain injury and concomitant intracranial injury. Methods: Retrospective review of the medical records of adult patients with traumatic intracranial injuries and an initial Glasgow Coma Scale sco

Two-Step Acoustophoresis Separation of Live Tumor Cells from Whole Blood

There is an unmet clinical need to extract living circulating tumor cells (CTCs) for functional studies and in vitro expansion to enable drug testing and predict responses to therapy in metastatic cancer. Here, we present a novel two-step acoustophoresis (A2) method for isolation of unfixed, viable cancer cells from red blood cell (RBC) lysed whole blood. The A2 method uses an initial acoustofluid

Blood-based biomarkers for Alzheimer's disease

Neurodegenerative disorders such as Alzheimer's disease (AD) represent a mounting public health challenge. As these diseases are difficult to diagnose clinically, biomarkers of underlying pathophysiology are playing an ever-increasing role in research, clinical trials, and in the clinical work-up of patients. Though cerebrospinal fluid (CSF) and positron emission tomography (PET)-based measures ar

The Relation Between Precarious Employment Arrangements and Social Precarity : Findings from the PREMIS Study in Stockholm, Sweden

Precarious employment (PE) is a well-known social determinant of health and health inequalities. However, as most previous studies have focused on physical and mental well-being, less is known about the social-related outcomes (ie, social precarity) associated with precarious arrangements. This cross-sectional study aims to investigate whether PE is associated with social precarity in a working po

Near-threshold two-photon double ionization of Kr in the vacuum ultraviolet

We report angle-resolved measurements on photoelectrons emitted upon near-threshold two-photon double ionization (TPDI) of Kr irradiated by free-electron laser (FEL) pulses. These photoelectron angular distributions (PADs) are compared with the results of semirelativistic R-matrix calculations. As reported by Augustin et al. [Phys. Rev. A 98, 033408 (2018)10.1103/PhysRevA.98.033408], it is found t

Fair heat distribution under deficits in district heating networks

In order to improve the energy efficiency in district heating networks and the comfort of their customers, these networks need to overcome the problem of unfair heat distribution under heat deficits. This paper introduces a new strategy to achieve this thermal fairness objective: it is lowcost in terms of communication and computation. The proposed approach is illustrated on a simulation example.

Videoessäer som pedagogisk metod för att utveckla medie- och informationskunnighet

Denna reflektion handlar om hur videoessän, som ett alternativ till mer traditionella examinationsformer, kan bidra till att utveckla studenters medie- och informationskunnighet. Videoessäns funktion i film- och medievetenskaplig utbildning presenteras. Därefter diskuteras det pedagogiska upplägget för kursen där videoessän ingick som examinationsmoment. En slutsats är att videoessän är en examina

Ut ur pandemin – rakt in i den digitala transformationen. Ska stadskärnans överlevnad bli en valfråga 2022?

Coronapandemin i kombination med ökad e-handel har varit ännu ett svårt slag mot svenska stadskärnor. Under 2020 och 2021 har flera stora butikskedjor valt att lämna stadskärnorna till förmån för externa handelsplatser och onlinehandel. Larmrapporterna och lösningar på problemet har varit många under 2021. Denna rapport är en analys och utvärdering av vad som sagts i media, tidigare forskning och

Exploring Populus phenological response to climate change using observational data and ecosystem modelling

The length of the growing season for deciduous trees in temperate and boreal forests is determined by the timing of bud burst and autumn senescence. It is generally assumed that a warmer climate leads to a longer growing season due to earlier bud burst and delayed autumn senescence and thereby increased gross primary production (GPP) of forests. In this study, we analysed past (1873–1951) and curr

Triple collocation-based error estimation and data fusion of global gridded precipitation products over the Yangtze River basin

Error estimation and data fusion are critical to improving the accuracy of global model- and satellite-based precipitation products for practical applications. However, they face challenges over vast areas of the world due to limited ground observations. Triple collocation (TC) method can overcome this limitation and provide an efficient way for error estimation without the “ground truth” and thus

The fate of icy pebbles undergoing sublimation in protoplanetary discs

Icy pebbles may play an important role in planet foation close to the water ice line of protoplanetary discs. There, dust coagulation is more efficient and recondensation of vapour on pebbles may enhance their growth outside the ice line. Previous theoretical studies showed that disruption of icy pebbles due to sublimation increases the growth rate of pebbles inside and outside the ice line, by fr

Photoacoustic Imaging of Enucleated Eyes from Patients with Uveal Melanoma can Reveal Extrascleral Growth

Background:Uveal melanoma is treated by either enucleation (removal of the eye) or local eye-sparing therapies, depending on tumor size and whether there are signs of extrascleral growth. Photoacoustic (PA) imaging is a novel imaging modality that provides high-resolution images of the molecular composition of tissues.Objective:In this study, the feasibility of PA imaging for uveal melanomas and d

Improving generalisation capability of artificial intelligence-based solar radiation estimator models using a bio-inspired optimisation algorithm and multi-model approach

One way of reducing environmental pollution is to reduce our dependence on fossil fuels by replacing them with solar radiation (Rs), which is one of the main sources of clean and renewable energy. In this study, daily Rs values at seven meteorological stations in Iran (Ahvaz, Isfahan, Kermanshah, Mashhad, Bandar Abbas, Kerman and Tabriz) over 2010-2019 were estimated using empirical models, suppor
