Evolution of Ices From Interstellar Space to the Solar System the degree of volatility of the various grain components is used to delineate their survival within the solar system. It is shown that only comets can preserve the interstellar dust in its primordial form. If the parent bodies of meteorites were formed at temperatures less than 500 K they would con

Formation History and Environment of Cometary Nucleition of the ice of the nucleus. For this basis, we propose a scheme for the formation of comets based on the theories on the evolution of the solar system. We describe the chemical composition of the ice of the nucleus inferred from the comparison of the abundances of cometary and interstellar molec

Stable Isotopic Compositions of Hydrogen, Carbon, Nitrogen, Oxygen and Sulfur in Meteoritic Low Tempng, and indeed before, the formation of the solar system. The more refractory light element-containing components preserve isotopic signatures recorded in pre-solar events or imparted in the high temperature regions of the solar nebula. The characteristics of the low temperature condensates in meteo

Dust of Variable Porosities (Densities) in the Solar Systems). Lunar Microcrater studies and in situ dust experiments have shown that the majority of the interplanetary dust particles are compact grains with densities between 3 and 8 g/cm., although ~ 20% of the interplanetary dust is of low density (<1 g/cm.). Under the assumption that cometary grains slow

C′ terminus and the amino acid sequence except for lysines that in PepFect14 are substituted with ornithines. Being non-proteinogenic amino acids, ornithines make PepFect14 less sensitive to serum proteases and due to its positive charges the CPP can form complexes with negatively charged cargos, s

J. Klingerle for epithelia relies on their ability to build an apical surface facing the outside world and a basolateral surface connecting cells together to coordinate their movements and resistance to stress. These epithelial features are dependent on several protein complexes for their establishment and ma

Mary L. Johnson,Andrea Schwake,Malcolm Nicol). This morphogenic step leads to rapid EC polarization in that apical and basal membrane domains are created, with fluid contacting the developing apical membrane surface, while ECM is in contact with the basal membrane surface. Interestingly, it has been difficult to identify specific apical vs. b
