HI1-2 and (3)-1, 7-BQCzHll-2, when treated with bases. The dicarbollide ions serve as
ligands in the formation of transition metal complexes which often resemble the well-known
metallocenes. The preparation, characterization, reactions, and structures of these …

A chemically defined serum‐free medium, which supports the development of bones and
fibrous tissues of rat calvaria from nonmineralized mesenchymal precursor tissues, was
employed to investigate tissue interactions between the dura mater and overlying tissues …

Previous studies suggest that normal wound repair requires the regulated production of
monocyte and macrophage chemoattractants. The current study examines the role of
monocyte chemoattractant protein‐1 (MCP‐1) in coordinating monocyte recruitment into …

In the past, alkylhydroquinones have been prepared through routes whichinvolved the

In all cases 0.10 mole of 1, 4-benzoquinone dissolved in diethyl ether was added under
nitrogen to a solution of 0.11 mole of trialkylborane in the same solvent at the reflux
temperature. The trialkylboranes employed were crude products obtained by hydroboration5 …

An optic signal transmit system and biasing method and apparatus and system is disclosed
to reduce power consumption during non-transmit periods. An optic signal generator
