BACKGROUND Molecular changes associated with the transition of melanoma cells from radial to vertical growth phase are not defined. To evaluate the role of VEGF in melanogenesis and determine its possible diagnostic and prognostic implications, we analyzed overexpression of VEGF in 202 cases of melanoma. MATERIALS AND METHODS Overexpression of VEGF was(More)
An electrolytic device for decomposition of water has been developed which readily gives hydrogen and oxygen for isotopic measurement with a mass spectrometer. A 20-mul sample can be decomposed quantitatively in 10 min with good reproducibility. The results produced are comparable with those obtained by reduction with uranium.
