IntroductionLegacy methods which provide us with quantitative information on asteroid composition are based on spectral unmixing or specific spectral parameters (band depths, band areas, positions of band minima). These methods are sensitive to quali

The Gaia mission of the European Space Agency (ESA) was launched in December 2013 and began it scientific operations in July 2014. Gaia is essentially devoted to the measurement of positions, parallaxes, proper motions, brightnesses, and colours of s

We propose a distributed close-range survey of hundreds of asteroids representing many asteroid families, spectral types and sizes. This can be implemented by a fleet of nanospacecraft (e.g., 4–5-unit CubeSats) equipped with miniature imaging and s

BACKGROUND Rupture in the shoulder region of a coronary atheroma is considered to be a sequel to local extracellular matrix degradation in this highly vulnerable site. Such degradation could be triggered by mast cells, which are filled with neutral p

Biochemical studies in vitro have demonstrated that stimulated mast cells induce macrophage foam cell formation through the synergistic action of mast cell granule neutral proteases and proteoglycans. To determine the presence and number of mast cell
