In a previous report of two patients with familial glucocorticoid resist ance due to reduced numbers of glucocorticoid receptors (GR), we have shown decreased numbers of GR in peripheral mononuclear cells and cultured fibroblasts but normal affinity of GR in both patients. In this study, peripheral lymphocytes from these patients, one patient's son and daughter, and normal subjects were transfo...

background: proliferating cell nuclear antigen (pcna) is a nuclear protein synthesized in the late g1 and s-phase of the cell cycle. detection of this protein represents a useful marker of the proliferation status of lesions. this study has been carried out to evaluate the cell proliferation rate in oral lichen planus (olp) and comparison between plaque and erosive lichen planus, which indicate...

A cytoplasmically anchored mutant SV40 T antigen, FS T antigen, was shown previously to interfere specifically with the nuclear import of a heterologous nuclear protein, adenovirus 5 fiber protein, in cultured monkey cells (Schneider, J., C. Schindewolf, K. van Zee, and E. Fanning. 1988. Cell. 54:117-125; van Zee, K., F. Appel, and E. Fanning. 1991. Mol. Cell. Biol. 11:5137-5146). In this repor...

introduction: using labeled peptides enjoys high importance in nuclear medicine. somatostatin analogs labeled with different radionuclide are vastly investigated for diagnosis or treatment of somatostatin receptor positive tumors. labeling somatostatin analogs with 99mtc as alternative of 111in needs doing different quality control method for determination of labeling yield and complex stabilit...

Methods: A pair of primers was designed to amplify herpes simplex virus type 1 and 2 (HSV-1/-2), EpsteinBarr virus (EBV) and cytomegalovirus (CMV). At last, we used the PCR-RFLP technique to differentiate four different herpesviruses. Meanwhile, 75 clinical blood specimens from infants of suspected viral infection and 38 blood specimens from healthy children were evaluated for herpesviruses DNA...

Antibodies in the sera of patients with systemic lupus erythematosus reacted with a nuclear acidic protein called Sm antigen, and these antibodies were used as reagents to identify Sm antigen in preparative fractionation procedures. DNA affinity chromatography showed that Sm antigen was associated with nuclear protein fractions which had DNA-binding capacity. Evidence was also presented that Sm...

AIM To evaluate the use of proliferating cell nuclear antigen index in the different histopathological variants of ameloblastoma, such as the follicular, plexiform, and unicystic types, and in ameloblastic carcinoma by immunohistochemical staining. The proliferating cell nuclear antigen index values of the variants of ameloblastomas and ameloblastic carcinomas are compared in order to determine...
