A glycophosphatidylinositol (GPI)-anchored form of the CD4 receptor was constructed by fusing the extracellular domain of CD4 to the COOH-terminus of decay accelerating factor (DAF), containing a signal for GPI-anchor attachment. The internalization

Locating the patient accurately in real time is necessary for many medical robotics applications. Current solutions are expensive or inconvenient. We show progress toward solving these problems by using ultrasound to track computed tomography (CT) re

The role of intravenously administered recombinant human transforming growth factor-beta 1 (rhTGF-beta 1) on the healing of incisional wounds in rats with impaired healing due to age or glucocorticoid administration was investigated. The administrati

Vascular endothelial growth factor (VEGF) is a mitogen with a specificity for endothelial cells in vitro and an angiogenic inducer in vivo. We tested the hypothesis that VEGF may confer on expressing cells a growth advantage in vivo. Dihydrofolatered

A conically tapered resistive disk with a single conducting hemisphere is used to effect the same energy selection as a pair of concentric hemispheres. The combination of this energy filter with a quadrupole mass spectrometer produces a secondary ion

Low energy (0–100 eV acceleration tandem quadrapole technique) and high energy (CID-MIKES technique) collision induced decomposition methods are compared, using selected methyl ketones. The compounds studied were acetone, 2-butanone, cyclopropyl me
