Nowadays organosilicon luminescent materials are of increasing interest due to the variety of their synthetic or modification techniques and application fields. Ladder polyphenylsilsesquioxanes(L-PPSQ) are a unique class of organosilicon polymers, which can be ideal matrices for the luminescent composites due to their high thermal stability, optical transparency and mechanical strength. In this work, new mechanically strong, heat-resistant, transparent and sensitive to ammonia vapor luminescent composite films based on L-PPSQ have been obtained. As the source of europium ions oligophenyleuropiumsiloxane was used, demonstrating perfect compatibility to the matrix due to the similar *** improve luminescent properties of the films, new organosilicon ligands were introduced into the composites and their influence on the properties of the materials was studied. Valuable properties of described composites may allow their further application as multifunctional coatings.

The mast cell is an enigmatic cell type whose physiological function has preoccupied large numbers of investigators for decadest. Some have concluded that the absence of mast cells is incompatible with life, at least in humans, because no human conditions have been documented where these cells are absent from the body. On the other hand, mice harboring specific mutations in certain growth factors, or their receptors, that

Adult tissue-derived organoids allow for the expansion and maintenance of primary epithelial cells in a near-native *** 3D and self-organizing organotypic cultures derived from adult tissues have been increasingly used in fundamental and translational research.A key feature of this organoid system is that it recapitulates the stem cell lineage and thus,the differentiated cell-type heterogeneity of the in vivo tissue of origin.
