Fish-hunting cone snail disrupts prey’s glucose homeostasis with weaponized mimetics of somatostatin and insulin

Venomous animals have evolved diverse molecular mechanisms to incapacitate prey and defend against predators. Most venom components disrupt nervous, locomotor, and cardiovascular systems or cause tissue damage. The discovery that certain fish-hunting cone snails use weaponized insulins to induce hypoglycemic shock in prey highlights a unique example of toxins targeting glucose homeostasis. Here, w

Targeted complement inhibition using bispecific antibodies that bind local antigens and endogenous complement regulators

Complement activation protects against infection but also contributes to pathological mechanisms in a range of clinical conditions such as autoimmune diseases and transplant rejection. Complement-inhibitory drugs, either approved or in development, usually act systemically, thereby increasing the risk for infections. We therefore envisioned a novel class of bispecific antibodies (bsAbs) which are

Prevalence of childhood cancer survivors in Europe : a scoping review

Childhood cancer survivors (CCS) require specialized follow-up throughout their lifespan to prevent or manage late effects of cancer treatment. Knowing the size and structure of the population of CCS is crucial to plan interventions. In this scoping review we reviewed studies that reported prevalence of CCS in Europe. We searched Medline, Web of Science, and Embase using permutations of terms refe

Palliative care services in paediatric oncology centres across Europe : A cross-sectional survey

Background: Palliative care (PC) is an integral part of cancer treatment. However, data on service availability is limited in childhood cancers. Aim: To describe the availability of PC services in paediatric oncology centres across Europe, and to identify barriers and facilitators for implementing and providing paediatric palliative care (PPC). Methods: Paediatric oncology centres across Europe we

Assembly and succession of the phyllosphere microbiome and nutrient-cycling genes during plant community development in a glacier foreland

The phyllosphere, particularly the leaf surface of plants, harbors a diverse range of microbiomes that play a vital role in the functioning of terrestrial ecosystems. However, our understanding of microbial successions and their impact on functional genes during plant community development is limited. In this study, considering core and satellite microbial taxa, we characterized the phyllosphere m

Seed treatment with clothianidin induces changes in plant metabolism and alters pollinator foraging preferences

Neonicotinoids, systemic insecticides that are distributed into all plant tissues and protect against pests, have become a common part of crop production, but can unintentionally also affect non-target organisms, including pollinators. Such effects can be direct effects from insecticide exposure, but neonicotinoids can affect plant physiology, and effects could therefore also be indirectly mediate

Gaia Data Release 3: Pulsations in main sequence OBAF-type stars

Context. The third Gaia data release provides photometric time series covering 34 months for about 10 million stars. For many of those stars, a characterisation in Fourier space and their variability classification are also provided. This paper focuses on intermediate- to high-mass (IHM) main sequence pulsators (M'a ¥''1.3'M') of spectral types O, B, A, or F, known as β Cep, slowly pulsating B (SP

Very high rotational frequencies and band termination in 73Br

Rotational bands in 73Br have been investigated up to spins of I = 65/2 using the EUROBALL III spectrometer. One of the negative-parity bands displays the highest rotational frequency ℏω= 1.85 MeV reported to date in nuclei with A ≥ 25. At high frequencies, the experimental J(2) dynamic moment of inertia for all bands decreases to very low values, J(2) ≤ 10ℏ2 MeV-1. The bands are described in the

Assessing the taxonomic status of Osmoderma cristinae (Coleoptera : Scarabaeidae), endemic to Sicily, by genetic, morphological and pheromonal analyses

Resolving complexes of closely related and cryptic insect species can be challenging, especially when dealing with rare and protected taxa that are difficult to collect for genetic and morphological analyses. Until recently, populations of the genus Osmoderma (Scarabaeidae), widespread in Europe, were treated as a single species O. eremita (Scopoli, 1763) in spite of observed geographic variation

Beta-decay properties of the neutron-rich 94-99Kr and 142-147Xe isotopes

Beta-decay half-lives and delayed-neutron emission probabilities of the neutron-rich noble-gas isotopes 94-99Kr and 142-147Xe have been measured at the PSB-ISOLDE facility at CERN. The results are compared to QRPA shell-model predictions and are used in dynamic calculations of r-process abundances of Kr and Xe isotopes.

Societal economic burden and determinants of costs for atopic dermatitis

Background: Atopic dermatitis (AD) is a common inflammatory skin disease while the economic burden of AD by severity is not adequately understood. Objective: To estimate the societal economic burden and to identify cost determinants of AD. Methods: In this population-based, controlled cohort study in Sweden, patients with AD were identified through diagnosis codes in primary or secondary care or b

Evolving therapies, neurocognitive outcomes, and functional independence in adult survivors of childhood glioma

Background: Treatment of childhood glioma has evolved to reduce radiotherapy exposure with the goal of limiting late toxicity. However, the associations between treatment changes and neurocognition, and the contribution of neurocognition and chronic health conditions to attainment of adult independence, remain unknown. Methods: Adult survivors of childhood glioma diagnosed in 1970-1999 in the Chil

Comparison of SP142 and 22C3 PD-L1 assays in a population-based cohort of triple-negative breast cancer patients in the context of their clinically established scoring algorithms

Background: Immunohistochemical (IHC) PD-L1 expression is commonly employed as predictive biomarker for checkpoint inhibitors in triple-negative breast cancer (TNBC). However, IHC evaluation methods are non-uniform and further studies are needed to optimize clinical utility. Methods: We compared the concordance, prognostic value and gene expression between PD-L1 IHC expression by SP142 immune cell

Accessible and reliable neurometric testing in humans using a smartphone platform

Tests of human brain circuit function typically require fixed equipment in lab environments. We have developed a smartphone-based platform for neurometric testing. This platform, which uses AI models like computer vision, is optimized for at-home use and produces reproducible, robust results on a battery of tests, including eyeblink conditioning, prepulse inhibition of acoustic startle response, a

Making Sense of Medical AI : AI transparency and the configuration of expertise

Artificial Intelligence (AI) technologies are increasingly researched and applied for medical knowledge discovery and to support or automate clinical decision-making. The aim of this thesis is to increase the knowledge on (1) how AI experts, radiologists, and standardizers make sense of AI, in the processes of medical AI development, clinical use and standardization, and (2) how this sensemaking c

Plasma p-tau217 in Alzheimer's disease : Lumipulse and ALZpath SIMOA head-to-head comparison

Plasma phosphorylated-tau217 (p-tau217) has been shown to be one of the most accurate diagnostic markers for Alzheimer's disease. No studies have compared the clinical performance of p-tau217 as assessed by the fully automated Lumipulse and single molecule array (SIMOA) AlZpath p-tau217. The study included 392 participants, 162 with Alzheimer's disease, 70 with other neurodegenerative diseases wit

IgA vasculitis nephritis - outcomes in adult-onset disease

Objectives: IgA vasculitis (IgAV) in adults has been relatively under-investigated. Since outcomes are worse in other forms of vasculitis with increasing age, we investigated the outcomes of IgAV comparing younger adults (18-34), middle-aged adults (35-64) and elderly patients (≥64 years) focusing on kidney outcomes. Methods: We identified patients with renal biopsy-confirmed IgAV nephritis and co

Defining Excellence : The First Core Set of Quality Indicators for the European Paediatric Surgical Audit on Hirschsprung's Disease Care

Aim: This study aimed to develop a universally applicable core set of quality indicators for Hirschsprung's disease care through a consensus-driven process, to standardise and improve care quality across Europe. Methods: A modified Delphi method was used to achieve consensus among healthcare professionals (HPs) and patient representatives (PRs) across Europe. Participants completed three rounds of

Lessons Learned from Early Implementation and Scale-up of Stool-Based Xpert Testing to Diagnose Tuberculosis in Children

In 2020, fecal (stool) testing was recommended for diagnosing Mycobacterium tuberculosis complex (MTBC) infection in children by using the Cepheid Xpert MTB/RIF assay; since then, countries have begun implementing stool-based testing, often as part of a comprehensive strategy to enhance TB case finding among children. On the basis of an experience-sharing workshop in November 2023, we determined i

Truly Supercritical Trade-Offs for Resolution, Cutting Planes, Monotone Circuits, and Weisfeiler–Leman

We exhibit supercritical trade-off for monotone circuits, showing that there are functions computable by small circuits for which any small circuit must have depth superlinear or even super-polynomial in the number of variables, far exceeding the linear worst-case upper bound. We obtain similar trade-offs in proof complexity, where we establish the first size-depth trade-offs for cutting planes an
