Effects of described demonstrator ability on brain and behavior when learning from others.

Observational learning enables us to make decisions by watching others' behaviors. The quality of such learning depends on the abilities of those we observe, but also on our beliefs about those abilities. We have previously demonstrated that observers learned better from demonstrators described as high vs.

Nonneutralizing antibodies in Nordic persons with moderate hemophilia A and B (the MoHem study).

Background: The impact of nonneutralizing antibodies (NNAs) in moderate hemophilia is elusive.

Objectives: To explore the presence of NNAs in Nordic persons with moderate hemophilia A (MHA) and B (MHB) in relation to treatment modality, clinical outcome, history of inhibitor, and the corresponding factor VIII (FVIII)/factor IX (FIX) gene mutation.

Methods: A cross-sectional multicenter study covering persons with MHA and MHB in Sweden, Finland, and Norway.

Empowering Regional Conservation: Genetic Diversity Assessments as a Tool for Eelgrass Management.

To halt the loss of biodiversity, collaboration among scientists, managers and decision-makers is vital. Although biodiversity loss is a global problem, management actions influencing diversity are often on a local to regional scale. Our study is an example of a regional conservation genomic assessment developed in collaboration between scientists and managers.

An integrative and translational PKPD modelling approach to explore the combined effect of polymyxin B and minocycline against Klebsiella pneumoniae.

Objectives: To expand a translational pharmacokinetic-pharmacodynamic (PKPD) modelling approach for assessing the combined effect of polymyxin B and minocycline against Klebsiella pneumoniae.

Methods: A PKPD model developed based on in vitro static time-kill experiments of one strain (ARU613) was first translated to characterize that of a more susceptible strain (ARU705), and thereafter to dynamic time-kill experiments (both strains) and to a murine thigh infection model (ARU705 only). The PKPD model was updated stepwise using accumulated data.

Measuring Patient-Reported Outcomes Following Traumatic Craniomaxillofacial Injuries: Development of the AO CMF Injury Symptom Battery.

Traumatic craniomaxillofacial (CMF) injuries are associated with various symptoms/concerns that affect patients' quality of life. The assessment of outcomes from the patient perspective has been limited by the absence of patient-reported outcome (PRO) measures tailored to this patient population. To address this need, we employed a mixed methods, multi-step process to first identify the most important symptoms/concerns and then use this information to construct a PRO symptom battery.

Preclinical Photodynamic Therapy Targeting Blood Vessels with AGuIX Theranostic Nanoparticles.

Glioblastoma multiforme (GBM) is the most common highly aggressive, primary malignant brain tumor in adults. Current experimental strategies include photodynamic therapy (PDT) and new drug delivery technologies such as nanoparticles, which could play a key role in the treatment, diagnosis, and imaging of brain tumors. The purpose of this study was to test the efficacy of PDT using AGuIX-TPP, a polysiloxane-based nanoparticle (AGuIX) that contains TPP (5,10,15,20-tetraphenyl-21H,23H-porphine), in biological models of glioblastoma multiforme and to investigate the vascular mechanisms of action at multiple complexity levels.

Environmental risk factors of Wilms tumour: A systematic review and meta-analysis.

Wilms tumour (WT) is the fourth leading cause of cancer death in children. Elucidating modifiable risk factors is crucial in identifying venues for primary prevention of the disease. This study aimed to review literature and synthesize environmental risk factors for WT.

Delusion-proneness predicts COVID-19 vaccination behavior.

Introduction: Vaccination-related conspiracy ideation is related to reduced compliance with public health advice globally. Such beliefs have previously been linked to the delusion-proneness trait. However, it is not known how this extends to getting vaccinated.

Pharmacological blocking of neutrophil extracellular traps attenuates immunothrombosis and neuroinflammation in cerebral cavernous malformation.

Cerebral cavernous malformation (CCM) is a neurovascular disease with symptoms such as strokes, hemorrhages and neurological deficits. With surgery being the only treatment strategy, understanding the molecular mechanisms of CCM is crucial in finding alternative therapeutic options for CCM. Neutrophil extracellular traps (NETs) were recently reported in CCM, and NETs were shown to have positive or negative effects in different disease contexts.

Neurofilament light in serum: Reference values and effect of risk factors for multiple sclerosis.

Background: The measurement of neurofilament light (NFL) in blood samples has been established as a sensitive measure of neuroaxonal damage in a wide range of diseases in the peripheral and central nervous system, including multiple sclerosis (MS). Previous studies have identified confounding factors that may influence the serum concentration of NFL.

Aim: We aimed at investigating the relationship between known confounders (age, body mass index, blood volume) and risk factors for MS (smoking and human leukocyte antigen (HLA)) on serum concentrations of NFL in control subjects.

Peer threat evaluations shape one's own threat perceptions and feelings of distress.

We are continuously exposed to what others think and feel about content online. How do others' evaluations shared in this medium influence our own beliefs and emotional responses? In two pre-registered studies, we investigated the social transmission of threat and safety evaluations in a paradigm that mimicked online social media platforms. In Study 1 (N = 103), participants viewed images and indicated how distressed they made them feel.

Calculation of continuous reference intervals for biological parameters exhibiting strong age-dependent level changes: Its application to glycosaminoglycans and sialic acid in urine.

Glycosaminoglycan (GAG) and sialic acid (total and free) assays are used as first-line screening tests for the diagnosis of mucopolysaccharidoses and glycoproteinoses, respectively. There is a pronounced age-dependent variation in the urinary concentrations of these metabolites in the normal population, and the stratification of the reference values into discrete age ranges may lead to an undesirably high number of false-positive or false-negative results. The aim of this study was to design a method for calculating continuous reference intervals as a function of age and its application to the analysis of GAGs and sialic acid (total, free, and conjugated) in urine.

A bispecific CD40 agonistic antibody allowing for antibody-peptide conjugate formation to enable cancer-specific peptide delivery, resulting in improved T proliferation and anti-tumor immunity in mice.

Current antibody-based immunotherapy depends on tumor antigen shedding for proper T cell priming. Here we select a novel human CD40 agonistic drug candidate and generate a bispecific antibody, herein named BiA9*2_HF, that allows for rapid antibody-peptide conjugate formation. The format is designed to facilitate peptide antigen delivery to CD40 expressing cells combined with simultaneous CD40 agonistic activity.

Socioeconomic status, smoking, and lung cancer: mediation and bias analysis in the SYNERGY study.

Background: Increased lung-cancer risks for low socioeconomic status (SES) groups are only partially attributable to smoking habits. Little effort has been made to investigate the persistent risks related to low SES by quantification of potential biases.

Methods: Based on 12 case-control studies, including 18 centers of the international SYNERGY project (16,550 cases, 20,147 controls), we estimated controlled direct effects (CDE) of SES on lung cancer via multiple logistic regression, adjusted for age, study center, and smoking habits, and stratified by sex.

AAV-mouse DNase I sustains long-term DNase I expression in vivo and suppresses breast cancer metastasis.

Neutrophil extracellular traps (NETs) have been implicated in the pathology of various inflammatory conditions. In cancer, NETs have been demonstrated to induce systemic inflammation, impair peripheral vessel and organ function and promote metastasis. Here we show that the plasma level of NETs is significantly higher in patients with metastatic breast cancer compared to those with local disease, or those that were considered cured at a 5-year follow-up, confirming NETs as interesting therapeutic targets in metastatic breast cancer.

Handholding reduces the recovery of threat memories and magnifies prefrontal hemodynamic responses.

Human touch is a powerful means of social and affective regulation, promoting safety behaviors. Yet, despite its importance across human contexts, it remains unknown how touch can promote the learning of new safety memories and what neural processes underlie such effects. The current study used measures of peripheral physiology and brain activity to examine the effects of interpersonal touch during safety learning (extinction) on the recovery of previously learned threat.

Supramolecular Control of Helicene Circularly Polarized Luminescence Emitters in Molecular Solids and Bright Nanoparticles.

Circularly polarized luminescence (CPL) from chiral molecules is attracting much attention due to its potential use in optical materials. However, formulation of CPL emitters as molecular solids typically deteriorates photophysical properties in the aggregated state leading to quenching and unpredictable changes in CPL behavior impeding materials development. To circumvent these shortcomings, a supramolecular approach can be used to isolate cationic dyes in a lattice of cyanostar-anion complexes that suppress aggregation-caused quenching and which we hypothesize can preserve the synthetically-crafted chiroptical properties.

From inspiration to restoration: Moral elevation as a catalyst for improving intergroup relations in contexts of conflict.

Existing research examining the creation of positive and prosocial interpersonal relations has established moral elevation as an approach-oriented emotion to be associated with a range of positive and prosocial outcomes. In this article and with the goal to identify emotional mechanism for improving intergroup relations in contexts of conflict, we examined the effects of moral elevation on enhancing relations. Across four experimental studies (s = 1,131), conducted in four understudied countries directly affected or threatened by intergroup conflict, we demonstrated that induced moral elevation elicits important cognitive and emotional shifts toward adversarial groups, resulting in improved intergroup relations.

Ecological genomics in the Northern krill uncovers loci for local adaptation across ocean basins.

Krill are vital as food for many marine animals but also impacted by global warming. To learn how they and other zooplankton may adapt to a warmer world we studied local adaptation in the widespread Northern krill (Meganyctiphanes norvegica). We assemble and characterize its large genome and compare genome-scale variation among 74 specimens from the colder Atlantic Ocean and warmer Mediterranean Sea.

Patients' experiences of clinical trial participation involving a product remotely assessing study drug adherence.

Background: The participation of patients in clinical trials is crucial for the development of healthcare. There are several challenges in the recruitment of trial participants with acute medical conditions. The registry-based randomized DAPA-MI clinical trial recruited patients during hospitalization for myocardial infarction and provided study drugs in bottles with smart caps that used wireless technology to transmit monitoring data.

The transfer of social threat learning to decision making is robust to extinction.

Through traditional mass media and online social media, we are almost constantly exposed to second-hand experiences of trauma and violence, providing ample opportunities for us to learn about threats through social means. This social threat learning can influence instrumental decision making through a social learning to decision-making transfer process, resembling the so-called Pavlovian to instrumental transfer effect, resulting in consequences that can be maladaptive. Here, we assessed if this influence could be diminished by extinction learning, a procedure where a previously threatening stimulus is learned to be safe, and thereby mitigate possible maladaptive consequences.

Age-corrected neurofilament light chain ratio decreases but does not predict relapse in highly active multiple sclerosis patients initiating natalizumab treatment.

Background: Neurofilament light chain (NFL) is a biomarker for monitoring disease activity and treatment response in multiple sclerosis (MS). However, while most agree that NFL levels predict disease activity and worsening, the predictive value of NFL on future relapse risk remains uncertain.

Objective: The primary aim was to evaluate the predictive value of age-corrected serum NFL (sNFL) ratio on relapse risk in highly active relapsing-remitting MS patients (RRMS) treated with natalizumab.
