Two isostructural Schiff base compounds, N c-[(2-hydroxy-3-methoxy)benzylidene]-3-hydroxybenzohydrazide monohydrate (1) and N c-[(2-hydroxy-3-ethoxy)benzyl idene]-3-hydroxybenzohydrazide monohydrate (2), have been synthesized by the condensation of 3-hydroxybenzohydrazide with 3-methoxysalicylaldehyde and 3-ethoxy salicyl aldehyde, respectively. The compounds have been characterized by el e men tal...
The patterns of differential gene expression were examined in two primary (A's) and two matched-metastatic (B's) head and neck squamous cell carcinoma (HNSCC) cell lines by differential display of mRNAs and northern blot hybridisation. Three cell lines used (PCI-04A, PCI-04B and PCI-06A) were established independently prior to therapy, whereas one cell line (PCI-06B) was established from a recurrent...
