Splicing is a central RNA-based process commonly altered in human cancers; however, how spliceosomal components are co-opted during tumorigenesis remains poorly defined. Here we unravel the core splice factor SF3A3 at the nexus of a translation-based program that rewires splicing during malignant transformation. Upon MYC hyperactivation, SF3A3 levels are modulated translationally through an RNA st

Small Cajal body-specific RNAs (scaRNAs) guide post-transcriptional modification of spliceosomal RNA and, while commonly altered in cancer, have poorly defined roles in tumorigenesis. Here, we uncover that SCARNA15 directs alternative splicing (AS) and stress adaptation in cancer cells. Specifically, we find that SCARNA15 guides critical pseudouridylation (Ψ) of U2 spliceosomal RNA to fine-tune AS

Stalling COVID-19 vaccination rates threaten public health. To increase vaccination rates, governments across the globe are considering using monetary incentives. We present evidence on the effect of guaranteed payments on COVID-19 vaccination uptake. We ran a large pre-registered randomized controlled trial (N = 8,286) in Sweden and linked the data to population-wide administrative vaccination re

A solid oxide fuel cell (SOFC) is a clean and high-efficiency energy conversion device, which undergoes improvement of performance continuously. The transport of gas species and charges proceed in the porous electrodes. The porous electrodes are also responsible for the removal of exhaust gases. In this paper, a fully coupled 3D single-channel multiphysics computational fluid dynamics (CFD) model

Resource management in cloud computing is a difficult problem, as one is often tasked with balancing between adequate service to clients and cost minimization in dynamic environments of many interconnected components. To make correct decisions in these environments, good performance models are necessary. A common modeling methodology is to use networks of queues, but as these are prohibitively exp

Experiences of intoxication elude scientific research because of their immediate and ‘inner’ nature for the intoxicated individual. In this chapter, we show how ‘trip reports’ – reports of psychedelic intoxication – from online drug information forums and libraries allow for further understanding the experience of psychedelic intoxication from LSD, DMT and psilocybin by examining psychonauts’ (i.e

Apolipoprotein A-I (ApoA-I) is the major protein constituent of high-density lipoprotein particles, and as such is involved in cholesterol transport and activation of LCAT (the lecithin:cholesterol acyltransferase). It may also form amyloidal deposits in the body, showing the multifaceted interactions of ApoA-I. In order to facilitate the study of ApoA-I in various systems, we have developed a pro

Background and Purpose: Diffusion-weighted MR imaging and fiber tractography can be used to investigate alterations in white matter tracts in patients with early acquired brain lesions and cerebral palsy. Most existing studies have used diffusion tensor tractography, which is limited in areas of complex fiber structures or pathologic processes. We explored a combined normalization and probabilisti

Purpose: The aim of the present study was to seek evidence of a relationship between damage to the optic radiation (OR) in the immature brain and subsequent development of the retinal nerve fiber layer (RNFL) and associated visual manifestations.Methods: Seven cases (2 males and 5 females ranging in age from 18 to 35 years old) were selected from a large cohort of individuals with known white matt

UNLABELLED: Diffusion MRI improves detection of abnormalities in white matter tracts in cerebral palsy (CP). Relationships between diffusion measurements and hand function are largely unexplored. We aimed first to assess microstructure of corticofugal fibers, and second to explore associations between tract injury as assessed by quantitative analysis of diffusion MRI and hand function in children

BACKGROUND: To describe visual field (VF) outcome in three adolescents with damage to the optic radiation and to focus on mechanisms that may compensate the practical functional limitations of VF defects.DESIGN: Descriptive, prospective multi-case study in a hospital setting.PARTICIPANTS: Three teenagers with cerebral visual dysfunction because of damage to the retro-geniculate visual pathways.MET

Allt sedan det amerikanska presidentvalet 2016 har det runt om i världen pågått en intensiv diskussion om utländska påverkansoperationer och hur och med vilken framgång främmande makter i det fördolda har sökt påverka demokratiska val, politisk opinion och politiska beslut i olika länder, däribland Sverige. Forskare, debattörer och politiker har särskilt framhållit att den nya informationsteknolog
