The CC chemokine receptor 2 (CCR2), a member of the G protein-coupled receptor (GPCR) superfamily, is widely involved in autoimmune and inflammatory diseases. However, no drugs for this receptor have made it to the pharmaceutical market yet.

Nowadays, it is well known that hydrogen and helium (and small traces of lithium and beryllium) were created shortly after the Big Bang, while the heavier elements are created in the cores of stars at different evolutionary stages. When these stars explode as supernovae, they expel metals synthesised…

Squatters and autonomous movements have been in the forefront of radical politics in Europe for nearly a half-century—from struggles against urban renewal and gentrification, to large-scale peace and environmental campaigns, to spearheading the antiausterity protests sweeping the continent.

Shining a light on the nefarious netherworlds of espionage, this is the first book to concentrate on the actual techniques and technologies used by early modern spies —from ciphers to counterfeiting, invisible inks to assassination

In this thesis, we have studied cell images from two types of cells, including pollen grains and the immune cells, neutrophils. These images are captured using a bright field microscope and a confocal microscope.

The Sun and all the stars in the night sky reside in the Milky Way galaxy. In the at-rest reference frame of the Galaxy, typical stars travel with velocities of about 100-200 kilometres per second.

Of all the mass in our Universe, 80% is thought to consist of a hypothetical and invisible substance called dark matter (DM).

Despite an increased EU role in the preparedness, monitoring and coordination of health emergencies over the past two decades, Member States’ responses to the first wave of COVID-19 were surprisingly uncoordinated. In light of calls to improve cooperation regarding future health emergencies, this article…

How do educational philosophies, discourses and practices spread around the globe, and how are they transformed and adapted locally?

The stratum corneum is the outermost skin layer and consists of dead cells embedded in a lipid matrix.

The authors examine the handling of cybercrime cases by law enforcement officers, focusing on bottlenecks and potential improvements noted by experts in the field.

The origin and evolution of galaxies are closely linked to many different physical phenomena.

By growing in a soil plants change the biotic and abiotic properties of the soil in which they grow.

In a new study, we found that when we are exposed to potential harm to the other person, it improves our automatic attentional processes to avoid harm to that person.

Self-assembly offers a promising route to create complex structures and materials using simple building blocks. Through, colloidal self-assembly, we can understand the governing principles of the self-assembly process and unlock its potential in diverse applications in materials science, photonics and…

Ramesh Ganohariti will examine legal identity in three post-Soviet aspirant states and outline four common scenarios in this article.

Acute cardiovascular syndromes, including myocardial infarction or stroke, are the principal cause of death in the Western society. The main underlying pathology of cardiovascular diseases is atherosclerosis, which is caused by the accumulation of lipids and inflammatory cells in the vessel wall, in…

Across many decision-making tasks, people and animals systematically repeat (or alternate) their choices - even when the choices they make are intrinsically uncorrelated. This phenomenon (also known as 'sequential effect' or 'choice hysteresis') has been known for at least a century, and may be a stable…

Stars and planets form within cold, dense clouds of gas and dust drifting through interstellar space. Although dust makes up only a small fraction of this material, it plays a key role in shaping the chemical evolution of these environments.

Sander Kok (35) was a hit as a model for Armani and he is now making a name for himself as a writer. His philosophically tinted first novel 'Smeltende vrouw' was acclaimed as a literary sensation. How do Literature Studies and Art History benefit him today?

Farmers do not love them all. Microbes can cause tragic consequences for crops. Even the presence of just one pathogenic fungus or bacterium can drastically reduce yields. Still, there are exceptions. In that case, a pathogenic microbe is present in the soil, but does not cause any harm. Adam Ossowicki…

A specifically designed collection of gears is soft on one end and rigid on the other. These are robust properties of the system that hold even in the presence of manufacturing imperfections. This emerging research area may lead to new ways of designing geared devices like satellite trackers or watches.…
