Highly expressed odorant receptor orthologs detect the aggregation pheromone lineatin in Trypodendron ambrosia beetles

Chemical communication using pheromones is crucial for the reproductive success of many insect species, including beetles(Coleoptera). Pheromones are detected by specialised odorant receptors (ORs), called pheromone receptors (PRs), in the sensoryneurons of the antennae. The PRs in Coleoptera remain understudied, with only a few receptors being functionally characterised.This limits our understand

Efficient and optimised resource allocation for augmented, virtual and mixed reality applications

Extended Reality (XR) serves as a broad term that encompasses several immersive technologies, including Augmented Reality (AR), Mixed Reality (MR), and Virtual Reality (VR). Currently, most XR devices are connected by cables, which restrict user mobility and negatively impact the overall Quality of Experience (QoE) for users. XR devices face limitations not only in terms of connectivity but also i

Ultra-hypofractionated radiotherapy with focal boost for high-risk localized prostate cancer (HYPO-RT-PC-boost) : in silico evaluation with histological reference

Background and purpose: The study aims to evaluate dosimetric properties of hypofractionated treatment plans integrating focal boost, using registered whole-mount histopathology (WMHP) as reference standard. Methods: Fifteen men from the PAMP trial (EudraCT: 2015-005046-55) were included. Participants had ≥ 1 ISUP Grade group ≥ 4 lesion and underwent [68Ga]prostate-specific membrane antigen (PSMA)

Flexibility of exercise capacity during nestling feeding in blue tits

Nestling feeding in altricial birds is a physiologically demanding phase of the annual cycle. Accordingly, parental effort in breeding songbirds has been suggested to be limited by the maximum capacity to perform sustained aerobic work. However, the maximum capacity for exercise and plasticity thereof is understudied in free-living, breeding songbirds. We tested two predictions related to the plas

The Nurses' Role in the Cardiac Rehabilitation Team : Data from the Perfect-CR Study

Background Nurses constitute a central profession in the cardiac rehabilitation (CR) team delivering comprehensive CR to individuals with cardiovascular disease. We aimed to identify specific components reflecting the nurses' role in the CR team associated with attainment of risk factor targets post myocardial infarction. Methods Center-level data (n = 78) was used from the Perfect-CR study, in wh

Personality Trait Changes After Device-Aided Therapy : Insights From Parkinson’s Patients and Their Close Relatives

Background: It is unclear whether the two device-aided therapies (DATs: deep brain stimulation [DBS] and levodopa–carbidopa intestinal gel [LCIG]) affect personality in patients with Parkinson’s disease (PD). Objective: This retrospective study aims to explore if patients with PD and their close relatives experience any changes in the patient’s personality following the start of DAT. Methods: In t

The Orientation to Life Questionnaire : Sense of Coherence

This chapter describes the core concept sense of coherence (SOC), in terms of definition, measurement, distribution, dimensionality and stability over time. The extensive evidence base of research after Antonovsky died, shows that SOC is a multidimensional and culturally sensitive life orientation. To date, the SOC questionnaire has been used in at least 73 countries all over the world. In additio

Local impact of roughness topography on heat transfer in turbulent flow over rough surfaces

Additive manufacturing (AM), particularly Laser Powder Bed Fusion, produces surfaces with unique, randomly distributed spherical roughness that significantly influences heat transfer and pressure loss. This study models AM roughness using a statistical distribution of spheres and performs high-fidelity simulations at a bulk Reynolds number of 12,000 to evaluate heat transfer on a rough pipe. Stati

Sexual Orientation and Personality Dimensions Measured by the Junior Temperament and Character Inventory among Adolescents

Research on adolescent sexual orientation has expanded in recent decades, yet little is known about its associations with personality traits during this developmental period. This study examined personality dimensions, as measured by the Junior Temperament and Character Inventory, across adolescent sexual orientation groups (asexual, homosexual, heterosexual, bisexual) in a community-based sample

The associations between parenting practices and adolescent alcohol use across mid-and late adolescence : A cohort study from Sweden

Background and aims: The aim of the present study is to examine the association between parenting practices and adolescent alcohol use in a longitudinal sample of adolescents from Sweden. Data and methods: A prospective longitudinal sample of 3,685 adolescents in a nationwide study in Sweden (2017-2019) filled out questionnaires. Baseline data (T1; 2017) was collected from participants at age 15 t

Influence of ethnicity on the diagnostic accuracy of plasma p-tau217 for the identification of Alzheimer's disease : A consecutive mixed memory clinic cohort study

INTRODUCTION: Blood-based biomarkers have demonstrated high accuracy for identifying Alzheimer's disease (AD) pathology. However, the lack of representative cohorts creates a knowledge gap regarding their real-world applicability. We examined the influence of ethnicity on the diagnostic accuracy of plasma tau phosphorylated at threonine 217 (p-tau217) in identifying AD. METHODS: A total of 1170 mi

The impact of common and rare genetic variants on bradyarrhythmia development

To broaden our understanding of bradyarrhythmias and conduction disease, we performed common variant genome-wide association analyses in up to 1.3 million individuals and rare variant burden testing in 460,000 individuals for sinus node dysfunction (SND), distal conduction disease (DCD) and pacemaker (PM) implantation. We identified 13, 31 and 21 common variant loci for SND, DCD and PM, respective

Vertical structure and kinematics of the LMC disc from SDSS/Gaia

Context. Studies of the internal kinematics of the LMC have provided a detailed view of its structure, largely thanks to the exquisite proper motion data supplied by the Gaia mission. However, line-of-sight (LoS) velocities, the third component of the stellar motion, are only available for a small subset of the current Gaia data, thus limiting studies of the kinematics perpendicular to the LMC dis

Land Use Change Consistently Reduces α- But Not β- and γ-Diversity of Bees

Land use change threatens global biodiversity and compromises ecosystem functions, including pollination and food production. Reduced taxonomic α-diversity is often reported under land use change, yet the impacts could be different at larger spatial scales (i.e., γ-diversity), either due to reduced β-diversity amplifying diversity loss or increased β-diversity dampening diversity loss. Additionall

AncestryGeni : a novel genetic ancestry classification pipeline for small and noisy sequence data

Motivation Efforts to address health disparities are often limited by the lack of robust computational tools for inferring genetic ancestry by calculating an individual's genetic similarity to continental groups. We have already shown that a preferred alternative to self-described race is using ancestry-informative markers (AIMs) that can be classified into ancestral components and used to estimat

Ultra-low-field brain MRI morphometry : Test–retest reliability and correspondence to high-field MRI

Magnetic resonance imaging (MRI) enables non-invasive monitoring of healthy brain development and disease. Widely used higher field (>1.5 T) MRI systems are associated with high energy and infrastructure requirements, and high costs. Recent ultra-low-field (<0.1 T) systems provide a more accessible and cost-effective alternative. However, it remains uncertain whether anatomical ultra-low-field neu
