Parenchymal pericytes are not the major contributor of extracellular matrix in the fibrotic scar after stroke in male mice

Scar formation after injury of the brain or spinal cord is a common event. While glial scar formation by astrocytes has been extensively studied, much less is known about the fibrotic scar, in particular after stroke. Platelet-derived growth factor receptor ß-expressing (PDGFRß+) pericytes have been suggested as a source of the fibrotic scar depositing fibrous extracellular matrix (ECM) proteins a

Explanation-by-norms

Philosophers’ search for the best way to explain human actions has led many to accept a core psychological model that can be supplemented by other forms of action explanation when needed. Rather than settling for this model – where everything ultimately hinges on psychological explanation – this paper argues for a pluralistic view. It does not claim that the psychological view is wrong, only that Philosophers’ search for the best way to explain human actions has led many to accept a core psychological model that can be supplemented by other forms of action explanation when needed.

On constructions of Lie (super) algebras and (, Î)-Freudenthal-Kantor triple systems defined by bilinear forms

In this work, we discuss a classification of (,Î)-Freudenthal-Kantor triple systems defined by bilinear forms and give all examples of such triple systems. From these results, we may see a construction of some simple Lie algebras or superalgebras associated with their Freudenthal-Kantor triple systems. We also show that we can associate a complex structure into these (,Î)-Freudenthal-Kantor triple

The Socio-Legal Relevance of Artificial Intelligence (report)

The report draws on socio-legal theory in relation to growing concerns over fairness, accountability and transparency of societally applied artificial intelligence (AI) and machine learning. The purpose is to contribute to a broad socio-legal orientation by describing legal and normative challenges posed by applied AI. To do so, the article first analyses a set of problematic cases, e.g. image rec

Molecular changes during progression from nonmuscle invasive to advanced urothelial carcinoma

Molecular changes occurring during invasion and clinical progression of cancer are difficult to study longitudinally in patient-derived material. A unique feature of urothelial bladder cancer (UBC) is that patients frequently develop multiple nonmuscle invasive tumors, some of which may eventually progress to invade the muscle of the bladder wall. Here, we use a cohort of 73 patients that experien

Transforming development and disaster risk

This article focuses on the complex relationship between development and disaster risk. Development and disaster risk are closely linked as the people and assets exposed to risk, as well as their vulnerability and capacity, are largely determined by development processes. Transformation is key to moving from current development patterns that increase, create or unfairly distribute risks, to forms

The contribution of sense of place to social-ecological systems research : A review and research agenda

To develop and apply goals for future sustainability, we must consider what people care about and what motivates them to engage in solving sustainability issues. Sense of place theory and methods provide a rich source of insights that, like the social-ecological systems perspective, assume an interconnected social and biophysical reality. However, these fields of research are only recently beginni

Depletion of the transcriptional coactivators CREB-binding protein or EP300 downregulates CD20 in diffuse large B-cell lymphoma cells and impairs the cytotoxic effects of anti-CD20 antibodies

Monoclonal antibodies targeting CD20 are central in the treatment of B-cell lymphomas. In diffuse large B-cell lymphoma (DLBCL), inactivating mutations of the histone acetyltransferases CREB-binding protein (CBP) and EP300 are common. Moreover, knockdown of CBP in DLBCL has been shown to result in aberrant transcriptional silencing. Expression of CD20 is sensitive to epigenetic manipulation, and h

Detailed phenotyping of posterior vs. anterior circulation ischemic stroke : a multi-center MRI study

Objective: Posterior circulation ischemic stroke (PCiS) constitutes 20–30% of ischemic stroke cases. Detailed information about differences between PCiS and anterior circulation ischemic stroke (ACiS) remains scarce. Such information might guide clinical decision making and prevention strategies. We studied risk factors and ischemic stroke subtypes in PCiS vs. ACiS and lesion location on magnetic

Choice Blindness, Confabulatory Introspection, and Obsessive–Compulsive Symptoms : Investigation in a Clinical Sample

The content of obsessions in obsessive–compulsive disorder (OCD) often run contrary to the actual self of the individual experiencing them. The ego-dystonic nature of obsessions has led some researchers to propose that individuals with OCD form these false beliefs about themselves due to limited introspective access. The current study therefore aimed to extend on recent findings from non-clinical

Systematic microbial production of optically active dissolved organic matter in subarctic lake water

The ecology and biogeochemistry of lakes in the subarctic region are particularly sensitive to changes in the abundance and optical properties of dissolved organic matter (DOM). External input of colored DOM to these lakes is an extensively researched topic, but little is known about potential reciprocal feedbacks between the optical properties of DOM and internal microbial processes in the water.

Rum, politik och ”meningslösa” upplopp : Ungdomsupplopp i Stockholm 1948–1965

Under efterkrigstiden skakades Stockholm återkommande av så kallade ungdomsupplopp, som av samtidens makthavare förstods som opolitiska, ja näst intill meningslösa i sin obegriplighet. Samtidigt låter händelserna oss resonera kring förhållandet mellan det offentliga rummet och människors kollektiva aktörskap. Genom att närma sig upploppen utifrån den politiska filosofen Jacques Rancières teorier o

Management and outcome of muscle-invasive bladder cancer with clinical lymph node metastases. A nationwide population-based study in the bladder cancer data base Sweden (BladderBaSe)

Purpose: To investigate the clinical management and outcome of patients with muscle-invasive bladder cancer with clinical lymph node involvement, using longitudinal nationwide population-based data. Methods: In the Bladder Cancer Data Base Sweden (BladderBaSe), treatment and survival in patients with urinary bladder cancer clinical stage T2–T4 N + M0 diagnosed between 1997 and 2014 was investigate

Voltage-manipulating graphene-mediated surface-enhanced Raman scattering (G-SERS) : principle and applications

The voltage-controlled graphene-mediated surface-enhanced Raman scattering (G-SERS) spectroscopy is experimentally developing spectral technology, and which is prosperously applied in the fields of ultra-sensitive spectral analysis, sensor and catalysis. In this review, we introduce the physical principle, fabrication method, and recent applications of voltage-controlled G-SERS. We firstly introdu

The sirius passet lagerstätte of north greenland : A remote window on the cambrian explosion

The lower Cambrian Lagerstätte of Sirius Passet, Peary Land, North Greenland, is one of the oldest of the Phanerozoic exceptionally preserved biotas. The Lagerstätte evidences the escalation of numbers of new body plans and life modes that formed the basis for a modern, functionally tiered ecosystem. The fauna is dominated by predators, infaunal, benthic and pelagic, and the presence of abundant n

Avian thermoregulation across age and seasons

Vilda djur påverkas ständigt av omgivningens temperatur som, tillsammans med ytterligare faktorer, styr många av de mönster och beteenden vi ser hos djur i naturen. Förändringar i temperatur kan till exempel påverka hur populationer och individer rör sig över tid och rum, när de väljer att fortplanta sig samt hur mycket föda som finns att tillgå. För jämnvarma djur, fåglar och däggdjur, som producAnimals constantly need to relate to prevailing environmental conditions and regulate their body temperature accordingly. Body temperature regulation in birds and mammals is inherently linked to energy expenditure and, thus, thermoregulation is a physiological mechanism that could trade-off with other costly processes, with potential long-term fitness consequences. In this thesis, I studied ecolog
