Introduction: Little is known of the processes that trigger neutrophil activation in the joint of patients with oligoarticular juvenile idiopathic arthritis (oJIA), and if synovial fibroblasts (S-Fib) play an important role in the activation. Therefore, we aimed to investigate whether S-Fib derived from oJIA patients drive neutrophil activation. Methods: Synovial fluid (SF) was collected from pati

This study employs computational algorithms to automatically identify and classify features in X-Ray fluorescence (XRF) microscopy images. Principal component analysis (PCA) and unsupervised machine learning algorithms, such as Gaussian mixture (GM) clustering, are implemented to label features on a collection of XRF maps of human atherosclerotic plaque samples. The investigation involves the hard

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

OBJECTIVE: The availability of tissue-mimicking materials (TMMs) for manufacturing high-quality phantoms is crucial for standardization, evaluating novel quantitative approaches, and clinically translating new imaging modalities, such as photoacoustic imaging (PAI). Recently, a gel comprising the copolymer styrene-ethylene/butylene-styrene (SEBS) in mineral oil has shown significant potential as T

Konsumtionen är en stor samtidsfråga, men trots att fler handlar allt mer medvetet är svenskarna fortfarande bland världens sämsta när det gäller överkonsumtion. Två forskare vid Lunds Universitet ser hur anti-konsumtionen växer sig allt starkare. Men kommer också näringslivet att förändras?

Firefighters can be occupationally exposed to a wide range of airborne pollutants during fire-extinguishing operations. The overall study aim was to characterize occupational exposure to smoke for several groups of workers responding to fires, with specific aims to determine the correlations between exposure markers and to biologically assess their systemic exposure to polycyclic aromatic hydrocar

Vocal problems are common among workers in voice demanding occupations. For sustaining vocal health, it is important to find efficient ways to reduce strain on the voice at work. One way to do so is optimizing the room acoustics for communication. However, we do not know enough about what kind of room acoustic conditions that support voice and speech most efficiently, and if talkers of different a

Aims/hypothesis: Roux-en-Y gastric bypass surgery (RYGB) frequently results in remission of type 2 diabetes as well as exaggerated secretion of glucagon-like peptide-1 (GLP-1). Here, we assessed RYGB-induced transcriptomic alterations in the small intestine and investigated how they were related to the regulation of GLP-1 production and secretion in vitro and in vivo. Methods: Human jejunal sample

Stem cell transplantation can improve behavioral recovery after stroke in animal models but whether stem cell-derived neurons become functionally integrated into stroke-injured brain circuitry is poorly understood. Here we show that intracortically grafted human induced pluripotent stem (iPS) cell-derived cortical neurons send widespread axonal projections to both hemispheres of rats with ischemic

Introduction Osteoarthritis (OA) is the most common form of arthritis and a leading cause of disability worldwide. Metabolic comorbidities such as type II diabetes occur with a higher rate in people with OA than in the general population. Several factors including obesity, hyperglycaemia toxicity and physical inactivity have been suggested as potential links between diabetes and OA, and have been

AIMS: Carbohydrate antigen 125 (CA125), a mucin produced by serosal cells in response to mechanical and inflammatory stimuli, has emerged as an important biomarker to guide risk stratification in heart failure (HF). The prognostic value of CA125 in acute coronary syndrome (ACS) patients is less explored.METHODS: In a cohort of 524 ACS patients (73% males, mean age 67 ± 12 years), we assessed the a

Background: The kidney injury molecule-1 (KIM-1) has previously been associated with kidney function in rodents and humans. Yet its role as a predictive marker for future decline in kidney function has remained less clear.Methods: At baseline (1991-1994), fasting plasma KIM-1 (p-KIM-1) was measured in 4739 participants of the population-based Malmö Diet and Cancer Study. Creatinine and cystatin C

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

Preclinical studies suggest that taurine may exert neuroprotective effects. However, its relevance to dementia risk in human populations remains unclear. We investigated the associations between mid-life dietary taurine intake, circulating taurine concentrations, and the risk of late-life all-cause dementia, Alzheimer's disease (AD), and vascular dementia (VaD) in a large prospective cohort. This

Bone Scan Index (BSI) is a quantitative measurement of tumour burden in the skeleton calculated from bone scan images. When analysed at the time of diagnosis, it has been shown to provide prognostic information on survival in men with metastatic prostate cancer (PCa). In this study, we evaluated the prognostic value of BSI during androgen deprivation therapy (ADT).
