Validation of the Super-Brief Pathological Narcissism Inventory (SB-PNI) among Swedish adolescents

This study examines the psychometric structure and properties of the Swedish version of the Super-Brief Pathological Narcissism Inventory (SB-PNI) among adolescents. In order to ensure the validity and feasibility of the measure, we examined the factor structure, measurement invariance across gender, age and ethnicity, and construct validity in relation to a number of correlates of narcissism in a

Gut-associated lymphoid tissue: a microbiota-driven hub of B cell immunity

The diverse gut microbiota, which is associated with mucosal health and general wellbeing, maintains gut-associated lymphoid tissues (GALT) in a chronically activated state, including sustainment of germinal centers in a context of high antigenic load. This influences the rules for B cell engagement with antigen and the potential consequences. Recent data have highlighted differences between GALT

The Quality of the Craft

In this study the sustainability of crucibles used during the Scandinavian Bronze Age is tested. Due to the crucible’s high or low sustainability the idea of it being a disposable object may be ratified or discarded. Earlier experiments focusing on the casting process in Scandinavian Bronze Age have concluded that crucibles such as the ones used during Bronze Age were disposable objects due to low

Exposure to Paracetamol in Early Pregnancy and the Risk of Developing Cerebral Palsy : A Case-Control Study Using Serum Samples

OBJECTIVE: To investigate whether maternal paracetamol use in early pregnancy is associated with cerebral palsy (CP) in offspring.STUDY DESIGN: We conducted a registry and biobank-based case-control study with mother-child pairs. We identified CP cases (n=322) born between 1995-2014 from a nationwide CP-registry. Randomly selected controls (n=343) and extra preterm controls (n=258) were obtained f

Cognitive functioning in adolescents with severe obesity undergoing bariatric surgery or intensive non-surgical treatment in Sweden (AMOS2): a multicentre, open-label, randomised controlled trial

Severe obesity during childhood is associated with cognitive deficits. Studies in adults have suggested improvements in executive functioning and memory after bariatric surgery. Our aim was to explore changes in cognitive function in adolescents over two years after bariatric surgery or intensive non-surgical treatment. Methods: The Adolescent Morbid Obesity Surgery 2 (AMOS2) is a multicentre, ope

Plurisubharmonic functions with discontinuous boundary behavior

We study the Dirichlet problem for the complex Monge–Amp`ereoperator with bounded, discontinuous boundary data. If the set of discontinuities is b-pluripolar and the domain is B-regular, we are able to prove existence, uniqueness and some regularity estimates for a large class of complexMonge–Amp`ere measures. This result is optimal in the unit disk, as boundaryfunctions with b-pluripolar disconti

Cyclic Structure Induced by Load Fluctuations in Adaptive Transportation Networks

Transport networks are crucial to the functioning of natural systems and technological infrastructures. For flow networks in many scenarios, such as rivers or blood vessels, acyclic networks (i.e., trees) are optimal structures when assuming time-independent in- and outflow. Dropping this assumption, fluctuations of net flow at source and/or sink nodes may render the pure tree solutions unstable e

Ultra-high field imaging of the human medial temporal lobe

Ultra-high field (UHF) imaging provides substantial benefits for the structural and functional investigation of the human medial temporal lobe. The medial temporal lobe is a complex system of many subregions that is critically involved in many cognitive functions and vulnerable to neurodegenerative processes. Here, we first lay out the benefits of UHF imaging for visualizing anatomical features wi

Amidst an amygdala renaissance in Alzheimer's disease

The amygdala was highlighted as an early site for neurofibrillary tau tangle pathology in Alzheimer's disease in the seminal Braak & Braak article (1991). This knowledge has, however, only received traction recently with advances in imaging and image analysis techniques. Here, we provide a cross-disciplinary overview of pathology and neuroimaging studies on the amygdala. These studies provide

Neural and behavioral correlates of episodic memory are associated with temporal discounting in older adults

When facing decisions involving trade-offs between smaller, sooner and larger, delayed rewards, people tend to discount the value of future rewards. There are substantial individual differences in this tendency toward temporal discounting, however. One neurocognitive system that may underlie these individual differences is episodic memory, given the overlap in the neural circuitry involved in imag

Associative memory for conceptually unitized word pairs in mild cognitive impairment is related to the volume of the perirhinal cortex

Unitization, that is, the encoding of an association as one integrated entity, has been shown to improve associative memory in populations presenting with associative memory deficit due to hippocampal dysfunction, such as amnesic patients with focal hippocampal lesions and healthy older adults. One reason for this benefit is that encoding of unitized associations would rely on the perirhinal corte
