Accurate 20 K intensity data were collected on a crystal of p-amino-p0-nitrobiphenyl [a = 24.348(1), b = 5.802 (1), c = 7.158 (1) AÊ , = = = 90 , space group Pca21] at the SUNY X3A1 beamline at the National Synchrotron Light Source, using a CCD area detector and a DISPLEX cryostat. The sharp vertical pro®le of the synchrotron beam, combined with a slight instability of the cryostat, necessitate...

immunohistochemical demonstration of tumor-associated markers may be valuable as an adjunct to conventional histology for determination of malignancy development in oral mucosal diseases. accordingly, the present study determined the distribution of some important tumor markers such as heat shock proteins (hsp), fibroblast growth factors (fgf) and transferrin receptors (tf-r) in 22 samples of p...

A recently developed procedure, that has been shown to be suitable for detailed immunohistological analysis, has been used to prepare cryostat sections of bone marrow to investigate whether enzyme-histochemical techniques are also feasible on such material. A selected group of enzymes, some of which are inhibited or destroyed in paraffin- or plastic-embedded samples, have been demonstrated. The...
