Mechanisms of homotypic lymphocyte aggregation and cell motility characteristics induced by activation of VLA integrins
Cell Adhesion may be modulated at the plasma membrane by intracellular signals or antibodies which confer an active ligand-binding conformation. Lymphocyte homotypic aggregation measured in tissue culture constitutes a ...
Receptor-specific binding of von Willebrand factor to platelets in response to shear stress
Physical and biochemical forces convert platelets in human blood in vivo from the quiescent state as freely moving, discoid, singlets to aggregates adhering to subendothelial surfaces and secreting a wide variety of bioactive ...
Ligand and genetic studies of the sulfate-binding protein and characterization of the calcium-binding site in the galactose-binding protein
The effect of pH on the binding affinities of the conjugate bases of four different tetrahedral oxyacids to the periplasmic sulfate-binding protein from Salmonella typhimurium has been determined. In light of the highly ...
Statistical and biophysical modeling of binaural interaction in the lateral superior olive
The Lateral Superior Olive (LSO) is believed to be involved in encoding high frequency localization information based on interaural level difference (ILD) and interaural time difference (ITD) cues. Details of how this ...
A model of lateral inhibition and directional selectivity in the crayfish compound eye
This study models the network interactions of five classes of neurons in the crayfish retina which support lateral inhibition and directional selectivity. The models approximate pulse responses and responses to drifting ...
Biodegradation of trichloroethene by ammonia-oxidizing bacteria: Kinetics, effects of mixtures, and toxicity
Trichloroethene is degraded by ammonia-oxidizing bacteria. In the absence of ammonia, TCE transformation proceeds at moderate rates. Under the experimental conditions tested, the presence of PCE and cis-DCE, competitive ...
