Mitochondrial dysfunction has been implicated in major depressive disorder (MDD). A measure of mitochondrial respiratory chain (RC) enzymatic activity—the Mitochondrial Health Index (MHI)—has previously been found to correlate with stress and emotional states in caregivers. We here report mitochondrial RC activities, mitochondrial DNA copy number (mtDNAcn), and the composite MHI in unmedicated and
Geospatial data are increasingly available nowadays, and this leads to more analyses and visualisation of geospatial data from several sources. To enable this, we need homogenous data as well as proper integration methods. Geospatial data integration has been a longstanding research topic for decades, and this paper discusses the utilisation of Linked Data technology stack to alleviate the geospat
Using NMR and Monte Carlo (MC) methods, we investigate the stability and dynamics of superoxide dismutase 1 (SOD1) in homogeneous crowding environments, where either bovine pancreatic trypsin inhibitor (BPTI) or the B1 domain of streptococcal protein G (PGB1) serves as a crowding agent. By NMR, we show that both crowders, and especially BPTI, cause a drastic loss in the overall stability of SOD1 i
Cancer-associated fibroblasts (CAFs) are a major constituent of the tumor microenvironment, although their origin and roles in shaping disease initiation, progression and treatment response remain unclear due to significant heterogeneity. Here, following a negative selection strategy combined with single-cell RNA sequencing of 768 transcriptomes of mesenchymal cells from a genetically engineered m
Background: Information is scarce on long-term changes in energy intake (EI), dietary energy density (DED), and body composition in adolescents undergoing laparoscopic Roux-en-Y gastric bypass (RYGB). Objectives: To investigate long-term changes in EI, DED, and body composition in adolescents after LRYGB. Setting: University hospitals, multicenter study, Sweden. Methods: Eighty-five adolescents (6
Prostate cancer is the most diagnosed cancer in men. The diagnosis is confirmed by pathologists based on ocular inspection of prostate biopsies in order to classify them according to Gleason score. The main goal of this paper is to automate the classification using convolutional neural networks (CNNs). The introduction of CNNs has broadened the field of pattern recognition. It replaces the classic
The tumor microenvironment can act so as to stimulate or reject tumor cells. Among the determining factors are cytokines produced, for example, by infiltrating immune cells, tumor cells, and fibroblasts. External radiotherapy has been shown to be able to activate an immune response against tumor cells with cytokine signaling as an important part of the activation. The aim of this study was to eval
The search for new cancer biomarkers is essential for fundamental research, diagnostics, as well as for patient treatment and monitoring. Whereas most cancer biomarkers are biomolecules, an increasing number of studies show that mechanical cues are promising biomarker candidates. Although cell deformability has been shown to be a possible cancer biomarker, cellular forces as cancer biomarkers have
Brottmekaniska processer ar något som intresserat människor i alla tider. Ibland har det varit för att vinna en fördel t ex vid tillverking av flintverktyg och malmbrytning, men oftast for att förhindra mekanisk kollaps. I det senare fallet kan oförsiktighet resultera i spruckna tallrikar eller trasiga fönster, men ocksa i allvarligare saker som brott i flygplansvingar eller fartygsskrov som i vär
The hepatokine follistatin is elevated in patients with type 2 diabetes (T2D) and promotes hyperglycemia in mice. Here we explore the relationship of plasma follistatin levels with incident T2D and mechanisms involved. Adjusted hazard ratio (HR) per standard deviation (SD) increase in follistatin levels for T2D is 1.24 (CI: 1.04-1.47, p < 0.05) during 19-year follow-up (n = 4060, Sweden); and 1.31
ObjectiveComputerized decision‐support tools may improve diagnosis of acute myocardial infarction (AMI) among patients presenting with chest pain at the emergency department (ED). The primary aim was to assess the predictive accuracy of machine learning algorithms based on paired high‐sensitivity cardiac troponin T (hs‐cTnT) concentrations with varying sampling times, age, and sex in order to rule
Endogenous retroviruses (ERVs) make up a large fraction of mammalian genomes and are thought to contribute to human disease, including brain disorders. In the brain, aberrant activation of ERVs is a potential trigger for an inflammatory response, but mechanistic insight into this phenomenon remains lacking. Using CRISPR/Cas9-based gene disruption of the epigenetic co-repressor protein Trim28, we f
Purpose - H2O, CO2 and CO are three main species in combustion systems which have high volume fractions. In addition, soot has strong absorption in the infrared band. Thus, H2O, CO2, CO and soot may take important roles in radiative heat transfer. To provide calculations with high accuracy, all of the participating media should be considered non-gray media. Thus, the purpose of this paper is to st
A sorption isotherm expresses the relation between ambient relative humidity (RH) and equilibrium moisture content of a material for a specific temperature. The sorption isotherm can generally be divided into a hygroscopic part covering low, medium and high RH levels, and an over-hygroscopic part close to 100% RH. For wood, the hygroscopic part is dominated by water uptake in cell walls and the ov
Background: Mild induced hypothermia (MIH) was introduced for post cardiac arrest care in Sweden in 2003, based on two clinical trials. This retrospective study evaluated its association with 30-day survival after out-of-hospital cardiac arrest (OHCA) in a Swedish community from 2003 to 2015. Methods: Out of 3680 patients with OHCA, 1100 were hospitalized after return of spontaneous circulation an
I detta kapitel beskrivs hur man vid Lunds tekniska högskola organiserar kursvärderingar som en del i ett övergripande arbete med rapporterande utvärdering av kurser. Syftet är att bidra med förståelse för hur olika konkreta problem förknippade med genomförandet av ett system för kursvärdering och utvärdering angripits på Lunds tekniska högskola. kapitlet visar också på hur Lunds tekniska högskola
