Abstract

The infra-red spectra of 1 : 1 complexes between benzene and chlorine, bromine, and iodine chloride have been studied, with the complexes isolated in a nitrogen matrix at 20 K. The results are interpreted as evidence for an oblique complex structure, with the halogen molecule interacting mainly with one of the C=C bonds.

Abstract

The Basic Linear Algebra Subprograms (BLAS) covering most basic vector operations have been widely used in numerical applications including LINPACK. The Extended Basic Linear Algebra Subprograms (EBLAS) were developed recently as an extension to the strictly vector operations of the BLAS. The EBLAS, also known as Level-2 BLAS, are a set of subprograms that represent basic matrix-vector operations and were written to take advantage of the architecture of today's supercomputers.

Abstract

TRANSFORMED CELLS are frequently less adhesive than normal cells. This decrease in adhesion has been associated with the loss of specific cell surface proteins, changes in morphology, alterations in the underlying cytoskeleton and the increased activity of the serine protease, plasminogen activator1–3. Hepatoma tissue culture (HTC) cells exhibit increased levels of adhesion to glass4,5 and decreased plasminogen activator activity6,7 when incubated in the presence of the synthetic glucocorticoid, dexamethasone. Plasminogen activator converts plasminogen in serum to plasmin. It has been shown that plasmin causes the reversible dissociation of intracellular actin-containing cables in anchorage-dependent rat embryo cells8 and may also be partially responsible for decreased adhesion of Rous sarcoma virus-transformed chicken embryo fibroblasts3. Cell–substrate adhesion presumably requires specific cell surface glycoproteins and intact cytoskeletal elements9,10. It is possible that plasmin acts either to modify ‘adhesive’ proteins on the cell surface or to disrupt linkages between these surface components and the underlying cytoskeleton. We have used variant HTC cells selectively resistant to the dexamethasone inhibition of plasminogen activator6 to test the hypothesis that hormonal induction of cell adhesion is secondary to the inhibition of plasminogen activator which in turn allows the accumulation of the glycoproteins necessary for adhesion. We have modified cell adhesion assay techniques5,11 to provide a sensitive measure of cell–substrate adhesion for both wild-type and variant HTC cells in the presence and absence of serum and plasminogen. We report here that plasminogen activator does not have an important role in the hormonal regulation of HTC cell adhesiveness.
