Nuclear localizing anti-DNA antibodies enter cells via caveoli and modulate expression of caveolin and p53.

After administration to normal mice, a subset of monoclonal (m) anti-DNA antibodies (Ab) derived from MRL-lpr/lpr mice was identified that enter cells, in vivo. In the kidneys, this was associated with glomerular hypercellularity and proteinuria. In cultured cells, the same mAb bound to myosin 1 on the cell surface, prior to internalization, nuclear localization and inhibition of apoptosis.

A simplified method for detecting isoniazid compliance in patients receiving antituberculosis chemotherapy.

The objective of this study was to develop a new simplified method using thin-layer chromatography (TLC) for determining isoniazid (INH) compliance in patients receiving antituberculosis chemotherapy. TLC was performed on silica gel plates using a standard solution of INH and acetylisoniazid (AcINH) and ethyl acetate-methanol (70:30 v/v) as the developing solvent. The spots of compound were detected by iodine.
