AFM study of lipid monolayers. 1. Pressure-induced phase behavior of single and mixed fatty acids

Monolayers of palmitic (C16:0) and lignoceric acid (C24:0) and their equimolar mixture were transferred to a hydrophilic mica substrate at various surface pressures and investigated by means of atomic force microscopy (AFM) in contact and lateral force modes. The first-order transition of lignoceric acid gives a plateau region, representing a liquid expanded to liquid condensed phase transition in

Dear territory or dear partner? Causes and consequences of breeding dispersal in a highly territorial bird of prey with a strong pair bond

Abstract: Territorial species are unlikely to show extensive movements between breeding seasons. This is especially true for long-lived species, which often have strong pair bonding and can occupy the same territory for years. However, also in such species, individuals may face situations that can lead to a territory shift. Here, we use a comprehensive dataset documenting 40 years of breeding beha

Impacts of large-scale Saharan solar farms on the global terrestrial carbon cycle

Amassing the available solar energy over the Sahara desert, through the installation of a large-scale solar farm, would satisfy the world’s current electricity needs. However, such land use changes may affect the global carbon cycle, possibly offsetting mitigation efforts. Here a fully coupled Earth System model EC-Earth was used to investigate the impact of a Saharan solar farm on the terrestrial

Metoprolol disrupts inflammatory response of human cardiomyocytes via β-arrestin2 biased agonism and NF-κB signaling modulation

Aims: Recent evidence supports non-class cardioprotective effects of metoprolol against neutrophil-mediated ischemia-reperfusion injury during exacerbated inflammation. Whether metoprolol exerts direct anti-inflammatory effect on cardiomyocytes is unknown. Accordingly, we aimed to investigate the direct anti-inflammatory effects of metoprolol in a cellular model of human induced pluripotent stem c

Influence of genetic variants and sialylation of purified κ-casein on peptide release during in vitro digestion

In the present study, digestion pattern of purified bovine κ-casein (κ-CN) variants A, B, E as well as desialylated variant B, using INFOGEST 2.0 in vitro gastrointestinal digestion were investigated using peptidomics. Peptide profiles of the digests were identified and quantified using ion abundancies by liquid chromatography electrospray quadropole time of flight mass spectrometry (LC-ESI/Q-TOF

Sintering in seconds, elucidated by millisecond in situ diffraction

Materials, when sintered at high temperatures, undergo structural changes on multiple, hierarchical length scales but getting realtime information on these changes is difficult. To address this challenge, we developed a custom-built sample environment that allows us to investigate the structural evolution of materials during sintering using high-energy two-dimensional synchrotron X-ray diffraction

In vivo hepatic flow distribution by computational fluid dynamics can predict pulmonary flow distribution in patients with Fontan circulation

In Fontan patients, a lung deprived of hepatic blood may develop pulmonary arterio-venous malformations (PAVMs) resulting in shunting, reduced pulmonary vascular resistance (PVR) and decreased oxygenation. To provide guidance for corrective invasive interventions, we aimed to non-invasively determine how the hepatic to pulmonary blood flow balance correlates with pulmonary flow, PVR, and with oxyg

Selective protein aggregation confines and inhibits endotoxins in wounds : Linking host defense to amyloid formation

Bacterial lipopolysaccharide (LPS) induces rapid protein aggregation in human wound fluid. We aimed to characterize these LPS-induced aggregates and their functional implications using a combination of mass spectrometry analyses, biochemical assays, biological imaging, cell experiments, and animal models. The wound-fluid aggregates encompass diverse protein classes, including sequences from coagul

The northernmost hyperspectral FLoX sensor dataset for monitoring of high-Arctic tundra vegetation phenology and Sun-Induced Fluorescence (SIF)

A hyperspectral field sensor (FloX) was installed in Adventdalen (Svalbard, Norway) in 2019 as part of the Svalbard Integrated Arctic Earth Observing System (SIOS) for monitoring vegetation phenology and Sun-Induced Chlorophyll Fluorescence (SIF) of high-Arctic tundra. This northernmost hyperspectral sensor is located within the footprint of a tower for long-term eddy covariance flux measurements

Recommendations for a core outcome measurement set for clinical trials in whiplash associated disorders

Inconsistent reporting of outcomes in clinical trials of treatments for whiplash associated disorders (WAD) hinders effective data pooling and conclusions about treatment effectiveness. A multidisciplinary International Steering Committee recently recommended 6 core outcome domains: Physical Functioning, Perceived Recovery, Work and Social Functioning, Psychological Functioning, Quality of Life an

A latent class analysis of mental disorders, substance use, and aggressive antisocial behavior among Swedish forensic psychiatric patients

Background: Patients in the forensic mental health services (FMHS) with a mental disorder, a co-occurring substance use disorder (SUD), and high risk of aggressive antisocial behavior (AAB) are sometimes referred to as the ‘triply troubled’. They suffer poor treatment outcomes, high rates of criminal recidivism, and increased risk of drug related mortality. To improve treatment for this heterogene

THE LATER LIFE AUDIO AND RADIO CO-OPERATIVE : Creating sustainable communities from participatory action research

This chapter considers the creation of the Later Life Audio and Radio Co-operative (LLARC) as an outcome of a participatory action research (PAR) project with a focus on facilitating later life civic participation. Developed in the UK, but with potential to become a global initiative, the LLARC is a collaborative network of older content creators, age-friendly radio stations, third-sector organisa

Gaia Data Release 3: Properties and validation of the radial velocities

Context. Gaia Data Release 3 (Gaia DR3) contains the second release of the combined radial velocities. It is based on the spectra collected during the first 34 months of the nominal mission. The longer time baseline and the improvements of the pipeline made it possible to push the processing limit from GRVS= 12 in Gaia DR2 to GRVS= 14 mag. Aims. We describe the new functionalities implemented for

Pedestrian/cyclist experience during dark conditions: A conceptual model

Walking and biking are active transport modes, that may be part of sustainable transport chains, thereby reducing car use. In the scientific literature, they have commonly been investigated separately (e.g. Ewing et al., 2006; Kellstedt et al., 2021), but since pedestrians and cyclists often share the same environments, it makes sense to consider them jointly. This research proposes a conceptual m

25-year trends in gender disparity for obesity and overweight by using WHO and IOTF definitions among Chinese school-aged children : a multiple cross-sectional study

OBJECTIVES: We sought to explore 25-year trends of gender disparity in the prevalence of obesity and overweight both in urban and rural areas among Chinese children from 1985 to 2010.METHODS: Data included 1 280 239 children aged 7-18 years enrolled in the Chinese National Survey on Students's Constitution and Health (CNSSCH), which is the largest nationally representative sample of school-aged ch

A cross-sectional study of sexual health knowledge, attitudes, and reported behavior among Zambian adolescent girl participants in a football program

Limited research has assessed whether sports participation can be linked to decreasing risky sexual behavior among adolescent girls in sub-Saharan Africa. The current study aimed to assess whether participation in a football league that provides sexual and reproductive health and rights lessons before each football match strengthened adolescent Zambian girls’ sexual health knowledge, attitudes, an

SENSITIVITY ANALYSIS OF THE ICRP BIOKINETIC MODEL PREDICTING THE ACTIVITY OF GD IN LUNGS AND 24-HOUR EXCRETION SAMPLES

148Gd may contribute to around 50% of the dose from inhalation in case of an accident at the European Spallation Source. Methods for its detection have been developed. They rely on biokinetic models predicting activities of the gamma emitters 146Gd (T1/2= 48.3 d) and 153Gd (T1/2= 240.4 d) as tracers in the lungs, urine, and faeces. The optimal choice of model parameters and associated uncertaintie

Addressing the Healthcare Needs of African Men who have Sex with Men: Barriers to Healthcare and Promoting HIV and STI Treatment in Sub-Saharan Africa.

Barriers to healthcare for men who have sex with men (MSM) in sub-Saharan Africa (SSA) are rooted in stigma and discrimination against MSM fuelled by the criminalization of homosexuality. These barriers are influenced by factors involving MSM and the healthcare workers (HCWs). MSM are uncomfortable disclosing their identities and conceal symptoms of sexually transmitted infections (STIs), especial
