The diagnostic value of a new tumor marker, CYFRA 21-1, was studied in the sera of 50 controls, 206 patients with benign diseases and 469 patients with malignancies. Fifty controls showed mean serum concentrations of 1.2 +/- 0.5 ng/ml. Using 3.3 ng/ml as the cutoff, abnormal CYFRA levels were found in 13.1% of patients with benign diseases, mainly in those(More)
The lily retrotransposon del 1-46 is 9345 base pairs (bp) long. It has long terminal repeats (LTRs) of 2406 bp (left) and 2415 bp (right), which differ in sequence by 1.4%. Sequences similar to those involved in priming DNA synthesis in retroviruses occur in the internal region. Near the left LTR is a sequence complementary to 18 residues at the 3' end of(More)
The distribution of enolase (EC 4.2.1.11) activity and isoenzymes in various regions of human brain at different ages (from 23 weeks of gestation to 95 years) and in brain tumors has been determined. Total enolase activity increased in all regions with age. No significant differences were found in the relative proportions of alpha alpha-, alpha gamma, and(More)
CYFRA 21-1, CEA, CA 125, SCC and NSE serum levels were determined in 50 healthy subjects and in 189 patients with primary lung cancer (101 with locoregional disease, 68 with recurrence and 20 patients with no evidence of residual disease (NED). Abnormal CYFRA 21-1 serum levels were found in 53.6% (90/168) of the patients with active cancer. Neither healthy(More)
Aims/background-In humans there are three phosphoglycerate mutase (PGM, EC 5.4.12.1) isoenzymes (MM, MB and BB) which have similar distribution and developmental pathways to creatine kinase (CK, EC 2.7.3.2) isoenzymes. Total serum PGM activity increases in acute myocardial infarction with the same time course as creatine kinase activity. The present study(More)
Two-dimensional gel electrophoresis followed by silver-staining has been employed to study 27 red cell lysates for genetic variation. Forty-six polypeptides selected without respect to variability were considered suitable for scoring. Only 23 of the total of 1,242 polypeptides could not be scored unambiguously. Of the remaining 1,219 polypeptides, 38(More)
Inflammatory myofibroblastic tumours (IMFT) may arise at any anatomical site, including lung, soft tissues, retroperitoneum and bladder. Although morphologically similar, these lesions encompass a spectrum of entities with differing aetiology, ranging from reactive/regenerative proliferations to low-grade neoplasms with a risk of local recurrence, but no(More)
TAG-72 is a tumor-associated antigen identified by the monoclonal antibody B72.3. Serum levels of TAG-72 were measured in patients with non-malignant and malignant disease. TAG-72 is not a specific marker of cancer and slightly elevated levels of this antigen can also be detected in the serum of healthy subjects. However, our results show that specificity(More)
We have compared the levels of phosphoglycerate mutase (EC 5.4.2.1), 2,3-bisphosphoglycerate phosphatase (EC 3.1.3.13), creatine kinase (EC 2.7.3.2) and enolase (EC 4.2.1.11) activities and the distribution of their isoenzymes in normal breast tissue and in breast carcinoma. Tumour tissue had higher phosphoglycerate mutase and enolase activity than normal(More)
