Mesenchymal stem cells (MSCs) are a new and promising tool for therapy of autoimmune disorders. In recent years their possibility to take part in the modulation of the immune response is discussed. The exact mechanisms for immunoregulation realized by MSCs are not clear yet, but interactions with other immunoregulatory cells may be involved in this process.… (More)
AIMS AND BACKGROUND The literature data show that the most frequently affected chromosomes in ovarian carcinogenesis are 1, 8 and 17. In the present study we aimed to define more precisely at a high resolution the genomic imbalances of these chromosomes in ovarian cancer and to determine genomic markers separating tumors of different histological types and… (More)
We construct a computable vector space with the trivial computable automorphism group but with a complicated dependence relation. Thus, we answer a question asked by A. Morozov in .
Cohesive sets play an important role in computability theory. Here we use cohesive sets to build nonstandard versions of the rationals. We use Koenigsmann's work on Hilbert's Tenth Problem to establish that these nonstandard fields are rigid. As a consequence we obtain results about automorphisms of the lattices of computably enumerable vector spaces… (More)
