The keystone species concept holds that certain members of an ecological community, despite their low abundance, exert disproportionately large effects on species diversity and composition. In microbial ecology, experimental validation of this concept has been limited because targeted removal of individual species remains technically challenging. Here, we developed a procedure to test the keystone

Hydrodeoxygenation (HDO) is a catalytic process applied for the reduction of oxygen levels in hydrocarbons from bio-derived feedstock as part of the processing into renewable fuel. The MoS2-based hydrotreating catalysts, currently being applied for the HDO reaction, are exposed to a complex environment consisting of O-rich hydrocarbons and water, which adversely impacts the state and stability of

Atomic layer deposition (ALD) of HfOx layers has emerged as a promising strategy for interface passivation in chalcopyrite-based thin-film solar cells. However, the nucleation dynamics of (Ag,Cu)(In,Ga)Se2 (ACIGS) absorbers remain insufficiently understood, particularly regarding the interplay between absorber composition and alkali postdeposition treatments (PDTs). Here, we employ in situ ambient

Objective: To investigate cellular immune responses to the herpes zoster (HZ) subunit (HZ/su) vaccine in patients with rheumatoid arthritis (RA) treated with Janus kinase inhibitors (JAKis). Methods: RA patients treated with JAKi (n=46) at the Department of Rheumatology, Skåne University Hospital, Sweden, and healthy controls (n=37) received two doses of the HZ/su vaccine. Blood samples were colle

Atrial fibrillation (AF) is a prevalent and morbid abnormality of the heart rhythm with a strong genetic component. Here, we meta-analyzed genome and exome sequencing data from 36 studies that included 52,416 AF cases and 277,762 controls. In burden tests of rare coding variation, we identified novel associations between AF and the genes MYBPC3, LMNA, PKP2, FAM189A2 and KDM5B. We further identifie

Animals align their body in relation to different environmental cues, including spontaneous directional responses relative to the geomagnetic field known as magnetic body alignment. The biological significance of this behavior, however, remains undetermined for most taxa. In previous studies, migratory songbirds aligned their body with the cardinal directions of the geomagnetic field and their mig

The focus of this study was to evaluate the feasibility of incorporating Perlin noise, a method that has previously been used to model the tissue distribution of software breast phantoms, when creating a ‘compressible’ software breast phantom used in finite element analysis. Several compressible phantoms were created to represent different stages of aging in a virtual patient when younger, fibrogl

Microplastics and nanoplastics (MNPs) are ubiquitous environmental pollutants with increasing implications for human health. While their presence in human tissues is established, the molecular mechanisms driving their potential neurotoxicity remain unclear. This study investigates the impact of polystyrene (PS) on amyloid protein misfolding and cellular metabolism using optical photothermal infrar

In socially monogamous species, extra-pair paternity (EPP) is predicted to increase variance in male reproductive success (RS) beyond that resulting from genetic monogamy, thus, increasing the “opportunity for selection” (maximum strength of selection that can act on traits). This prediction is challenging to investigate in wild populations because lifetime reproduction data are often incomplete.

The human pathogen Streptococcus pyogenes causes substantial morbidity and mortality. It is unclear if antibodies developed after infections with this pathogen are opsonic and if they are strain specific or more broadly protective. Here, we quantified the opsonic-antibody response following invasive S. pyogenes infection. Four patients with S. pyogenes bacteremia between 2018 and 2020 at Skåne Uni

Dysphagia, or difficulty swallowing, affects 10–30 % of persons above 65 years old. Texture-modified, easy-to-swallow, puree-like food in the form of timbales is usually served to this group of patients. Due to the characteristics of timbale, its appearance only remotely reminds of the original ingredients, leading to reduced appetite, reduced nutrition intake, and even malnutrition. 3D food print

The MM500 meta-study aims to establish a knowledge basis of the tumor proteome to serve as a complement to genome and transcriptome studies. Somatic mutations and their effect on the transcriptome have been extensively characterized in melanoma. However, the effects of these genetic changes on the proteomic landscape and the impact on cellular processes in melanoma remain poorly understood. In thi

BACKGROUND: Five classic thrombophilias have been recognized: factor V Leiden (rs6025), the prothrombin G20210A variant (rs1799963), and protein C, protein S, and antithrombin deficiencies. This study aimed to determine the thrombotic risk of classic thrombophilias in a cohort of middle-aged and older adults. METHODS AND RESULTS: Factor V Leiden, prothrombin G20210A and protein-coding variants in

Commentary and analysis of the proposal of the Swedish Ministry of Justice (Ds 2021:30) concerning implementation of Article 17 Directive 2019/790 on copyright and related rights in the Digital Single Market (DSM Directive). Part 1 of 2.

Det är mycket rörelse på AI-fronten nu – både rättsligt, tekniskt och politiskt. Stefan Larsson, jurist och docent i teknik och social förändring vid Lunds universitet, placerar in EU-lagstiftarens AI-förordning i en både global och svensk kontext. Han beskriver processen bakom lagstiftningen, de etiska och principiella grunderna, och hur EU-lagstiftaren hanterar AI-innovationernas explosionsartad

Due to its inherent structural fragility, the lung is regarded as one of the more difficult tissues to process for microscopic readouts. To add structural support for sectioning, pieces of lung tissue are commonly embedded in paraffin or OCT compound and cut with a microtome or cryostat, respectively. A more recent technique, known as precision-cut lung slices, adds structural support to fresh lun
