Low-level internalization of cystatin E/M affects legumain activity and migration of melanoma cells

The ratio between proteases and their inhibitors is unbalanced in cancer. The cysteine protease inhibitor cystatin C is internalized by some cancer cells, which affects cellular properties. Here we aimed to investigate if uptake of cystatin C and the related inhibitor cystatin E/M occur in melanoma cell lines and to evaluate to what extent the uptake affects the legumain activity that is typically

Getting used to diversity? Immigration and trust in Sweden

This paper studies what effect past regional experiences of immigration has on how people react to recent immigration in terms of social trust. The effect of present-day diversity on trust is compared across two groups of regions in Sweden: one group with low levels of past immigration and one group with high levels of past immigration. The results clearly show that people in regions with high lev

Identification of islet-enriched long non-coding RNAs contributing to β-cell failure in type 2 diabetes

Objective: Non-coding RNAs constitute a major fraction of the β-cell transcriptome. While the involvement of microRNAs is well established, the contribution of long non-coding RNAs (lncRNAs) in the regulation of β-cell functions and in diabetes development remains poorly understood. The aim of this study was to identify novel islet lncRNAs differently expressed in type 2 diabetes models and to inv

QmeQ 1.0 : An open-source Python package for calculations of transport through quantum dot devices

QmeQ is an open-source Python package for numerical modeling of transport through quantum dot devices with strong electron-electron interactions using various approximate master equation approaches. The package provides a framework for calculating stationary particle or energy currents driven by differences in chemical potentials or temperatures between the leads which are tunnel coupled to the qu

Are parrots poor at motor self‐regulation or is the cylinder task poor at measuring it?

The ability to inhibit unproductive motor responses triggered by salient stimuli is a fundamental inhibitory skill. Such motor self-regulation is thought to underlie more complex cognitive mechanisms, like self- control. Recently, a large-scale study, comparing 36 species, found that absolute brain size best predicted competence in motor inhibition, with great apes as the best performers. This was

Co film stretching induced by lattice mismatch and annealing : The role of Graphene

Thin Co films intercalated between a Graphene capping layer and the Ir(111) surface are of interest for spintronics applications due to their peculiar magnetic properties and to their chemical stability. The structure, and then the magnetic properties, of the Co films depend on the intercalation process which is strongly influenced by the temperature, total amount of Cobalt and quality of the capp

Radioecological modelling of Polonium-210 and Caesium-137 in lichen-reindeer-man and top predators

This work deals with analysis and modelling of the radionuclides 210Pb and210Po in the food-chain lichen-reindeer-man in addition to 210Po and 137Cs in top predators. By using the methods of Partial Least Square Regression (PLSR) the atmospheric deposition of 210Pb and 210Po is predicted at the sample locations. Dynamic modelling of the activity concentration with differential equations is fitted

The effect of the pocket on the heat transfer of endwall with bluff body in the rear part of gas turbine

A pocket cavity is generated at the connection of two parts, such as the transition part between the low pressure turbine (LPT) and outlet guide vane (OGV) in a gas turbine engine. A bluff body, working as a heat transfer enhancement part or supporting strength part, has tremendous engineering applications in turbomachinery. In the present work, the effect of the pocket on the heat transfer of end

In search of academic legitimacy : The current state of scholarship on graffiti and street art

Much has changed since the 1960s when the first scholarship on contemporary graffiti appeared. The current paper is an attempt to outline and contextualize a number of recurrent challenges facing researchers of graffiti and street art, as well as developments that have taken place in this scholarly field. The aim of creating this outline is to assist in increasing the amount, and improving the qua

Care professional's experiences about using Liverpool Care Pathway in end-of-life care in residential care homes

Background: Residential care homes (RCHs) play an important role in end-of-life care, being the most common place of death for elderly people in several European countries. Care pathways such as the Liverpool Care Pathway for the Dying Patient (LCP) are used to improve and ensure quality care at the end of life. There is a lack of scientific evidence supporting the use of care pathways. Design: A

Female exposure to phthalates and time to pregnancy : A first pregnancy planner study

STUDY QUESTION Is female exposure to phthalate metabolites associated with reduced fecundity, as estimated by prolonged time to pregnancy (TTP)? SUMMARY ANSWER Female exposure to monoethyl phthalate (MEP) but not monobutyl phthalate (MBP), monobenzyl phthalate (MBzP) and monoethylhexyl phthalate (MEHP) was associated with a longer TTP. WHAT IS KNOWN ALREADY Male exposure to phthalates is potential

CD44 interacts with HIF-2α to modulate the hypoxic phenotype of perinecrotic and perivascular glioma cells

Hypoxia-inducible factors enhance glioma stemness, and glioma stem cells have an amplified hypoxic response despite residing within a perivascular niche. Still, little is known about differential HIF regulation in stem versus bulk glioma cells. We show that the intracellular domain of stem cell marker CD44 (CD44ICD) is released at hypoxia, binds HIF-2α (but not HIF-1α), enhances HIF target gene ac

Exploitation of an atmospheric lidar network node in single-shot mode for the classification of aerofauna

The migration of aerofauna is a seasonal phenomenon of global scale, engaging billions of individuals in long-distance movements every year. Multiband lidar systems are commonly employed for the monitoring of aerosols and atmospheric gases, and a number of systems are operated regularly across Europe in the framework of the European Aerosol Lidar Network (EARLINET). This work examines the feasibil

Structural Characterization of Bubbles Formed in DNA Melting : A Monte Carlo Simulation Study

Bubbles in DNA are involved in many important biological processes. In this work, a coarse-grained model is used for characterizing bubbles formed in DNA melting. The model resorts only to electrostatic interactions at the Debye-Hückel level, in combination with a short-ranged attractive interaction within a base pair. In spite of also omitting atomistic details, the model is able to capture exper
