In the course of the Horizon 2020 project HighNESS, a second moderator concept has been developed for the European Spallation Source, which complements the currently built moderator and is optimized for high intensity with a large viewable surface area. In this work we introduce conceptual designs for neutron instruments for condensed matter research designed to make optimal use of the capabilities of this moderator. The focus is on two concepts for small-angle neutron scattering and one neutron imaging instrument, which are intended to complement corresponding instruments that are already under construction at the European Spallation Source...

The route and speed of migration into Sahul by Homo sapiens remain a major research question in archaeology. Here, we introduce an approach which models the impact of the physical environment on human mobility by combining time-evolving landscapes with Lévy walk foraging patterns, this latter accounting for a combination of short-distance steps and occasional longer moves that hunter-gatherers likely utilised for efficient exploration of new environments. Our results suggest a wave of dispersal radiating across Sahul following riverine corridors and coastlines...

The fusion of neurotrophic tyrosine receptor kinase (NTRK) is a novel target for cancer therapy and offers hope for patients with gastric cancer (GC). However, there are few studies on the prevalence and detection methods of NTRK fusions in GC. In this study, we used immunohistochemistry (IHC) as a screening method to select cases for molecular testing and evaluated the effectiveness of IHC, fluorescence in situ hybridization (FISH), and next-generation sequencing (NGS). We retrospectively collected 1970 patients with GC...

BACKGROUND/OBJECTIVES: Ocular surface squamous neoplasia (OSSN) are among the most frequent non-pigmented malignancies of the ocular surface. They have a wide range of histological characteristics - ranging from mild epithelial dysplasia to invasive carcinoma of the squamous cells of the cornea. They may be restricted to the conjunctiva or also involve the cornea. As there are no leading symptoms in the early stages, diagnosis may be very delayed in patients who do not receive regular ophthalmological treatment...

BACKGROUND: Active surveillance pharmacovigilance is an emerging approach to identify medications with unanticipated effects. We previously developed a framework called pharmacopeia-wide association studies (PharmWAS) that limits false positive medication associations through high-dimensional confounding adjustment and set enrichment. We aimed to assess the transportability and generalizability of the PharmWAS framework by using medical claims data to reproduce known medication associations with Clostridioides difficile infection (CDI) or gastrointestinal bleeding (GIB)...

Several studies have shown that anxious individuals experience a slower passage of time under threat conditioning. Anxiety-evoking situations have also been proposed to elevate arousal levels, which, in turn, alter one's time percept. However, the effect of social stressors on time perception remains significantly neglected. The current research aimed to investigate the impact of anxiety levels on time estimation and passage of time judgments during public speaking in healthy adults. Participants were recruited from a pool of students that had to give a presentation as part of a university course or their teaching duties...

Drug repurposing is promising in multiple scenarios, such as emerging viral outbreak controls and cost reductions of drug discovery. Traditional graph-based drug repurposing methods are limited to fast, large-scale virtual screens, as they constrain the counts for drugs and targets and fail to predict novel viruses or drugs. Moreover, though deep learning has been proposed for drug repurposing, only a few methods have been used, including a group of pre-trained deep learning models for embedding generation and transfer learning...

In the face of the increasingly severe problem of antibiotic resistance, phage therapy is regarded as a highly potential alternative. Compared with traditional antimicrobial agents, a key research area of phage therapy is the study of phage-resistant mutant bacteria. To effectively monitor and prevent this resistance, it is crucial to conduct in-depth exploration of the mechanism behind phage resistance. In this study, a strain of Salmonella enteritidis (sm140) and the corresponding phage (Psm140) were isolated from chicken liver and sewage, respectively...

INTRODUCTION: Systemic lupus erythematosus (SLE) causes kidney compromise in up to 40% of patients, contributing significantly to morbidity. Lupus nephritis (LN), an early onset manifestation in most patients, is histologically classified into six types, with types III, IV, and V requiring treatment with induction therapies, usually glucocorticoids with mycophenolate mofetil (MMF) or intravenous cyclophosphamide (IVC). However, up to 60% of patients fail to achieve complete remission, and 27%-66% have subsequent flares...

In fungi, fusion between individuals leads to localized cell death, a phenomenon termed heterokaryon incompatibility. Generally, the genes responsible for this incompatibility are observed to be under balancing selection resulting from negative frequency-dependent selection. Here, we assess this phenomenon in Aspergillus fumigatus, a human pathogenic fungus with a very low level of linkage disequilibrium as well as an extremely high crossover rate. Using complementation of auxotrophic mutations as an assay for hyphal compatibility, we screened sexual progeny for compatibility to identify genes involved in this process, called het genes...

Existing studies have shown that the abnormal expression of microRNAs (miRNAs) usually leads to the occurrence and development of human diseases. Identifying disease-related miRNAs contributes to studying the pathogenesis of diseases at the molecular level. As traditional biological experiments are time-consuming and expensive, computational methods have been used as an effective complement to infer the potential associations between miRNAs and diseases. However, most of the existing computational methods still face three main challenges: (i) learning of high-order relations; (ii) insufficient representation learning ability; (iii) importance learning and integration of multi-view embedding representation...

The issue of traffic congestion poses a significant obstacle to the development of global cities. One promising solution to tackle this problem is intelligent traffic signal control (TSC). Recently, TSC strategies leveraging reinforcement learning (RL) have garnered attention among researchers. However, the evaluation of these models has primarily relied on fixed metrics like reward and queue length. This limited evaluation approach provides only a narrow view of the model's decision-making process, impeding its practical implementation...

Understanding nanoparticle-cell interaction is essential for advancing research in nanomedicine and nanotoxicology. Apart from the transcytotic pathway mediated by cellular recognition and energetics, nanoparticles (including nanomedicines) may harness the paracellular route for their transport by inducing endothelial leakiness at cadherin junctions. This phenomenon, termed as NanoEL, is correlated with the physicochemical properties of the nanoparticles in close association with cellular signalling, membrane mechanics, as well as cytoskeletal remodelling...

The purpose of this article was to present a step-by-step guide to the surgical anatomy of this procedure. It is composed of a 7-stage approach, enhancing access to and improving visualization of deep structures. METHODS: A retrospective analysis of 39 pediatric patients with refractory epilepsy who underwent this technique was conducted...

Hidradenitis suppurativa (HS) is a chronic inflammatory skin condition characterized by painful inflammatory lesions, predominantly affecting areas of the skin rich in apocrine glands, such as inguinal, axillary, submammary, and anogenital regions, with an estimated global prevalence between 1%-4%. The treatment of HS is challenging with various treatment modalities employed to control the disease. Since the condition is chronic and life-impairing, many patients have looked for ways to complement their conventional treatment procedures with non-medical interventions, among which dietary interventions have been of particular interest...

A 47-year-old male patient diagnosed with severe obstructive sleep apnea (OSA) sought alternatives to positive airway pressure, prompting evaluation with drug-induced sleep endoscopy (DISE). He underwent a specialized DISE with nasal airflow and pharyngeal pressure monitoring. During obstructive apneas, airflow and pressure signals demonstrated dynamic, multilevel upper airway collapse, with shifting sites of airflow obstruction as respiratory effort increased. This case report illustrates how quantitative airflow and pressure measurements can complement the standard DISE exam and aid in surgical decision-making...

The co-occurrence of myasthenia gravis (MG) and paroxysmal nocturnal hemoglobinuria (PNH) is rare; only one case has been published so far. We report a 63-year-old Caucasian female patient who was diagnosed with MG at the age of 43. Thymoma was also detected, and so it was surgically resected, which resulted in reasonable disease control for nearly 20 years. Slight hemolysis began to emerge, and then myasthenia symptoms progressed, so immunosuppressive therapy was started. Due to progressive disease and respiratory failure, the patient underwent plasmapheresis, and ventilatory support was stopped...

Sugarcane smut, caused by the fungal pathogen Sporisorium scitamineum , is a prominent threat to the sugarcane industry. The development of smut resistant varieties is the ultimate solution for controlling this disease, due to the lack of other efficient control methods. Artificial inoculation method is used to evaluate the virulence differentiation of pathogens. The mostly used artificial inoculation methods are soaking of the seed canes in the teliospore solution and injection of teliospores or haploid sporidia into the sugarcane sprouts...
