Current work proposes an inimitable composite, with great electrical conductivity and quite enhanced surface area, (including conducting polymers (poly (cathechol)), Cu2O–carbon dots and green synthesized gold nanoparticles) for detecting acute carcinoembryonic antigen. At current work, the electropolymerization was offered instead of enzyme-catalyzed polymerization of poly (catechol). <b...

background: efficient screening for detection of colorectal cancer (crc) at earlier stages reduces its mortality. the purpose of this study was to investigate expression of carcinoembryonic antigen (cea) and human telomerase reverse transcriptase (htert) mrna in peripheral blood of crc patients and to present strategies for early detection screen test. methods: twenty seven patients in non-meta...

introduction: although extensive research has been conducted on lung cancer markers, a singular clinically applicable marker has not been found yet. the objective of this study was to evaluate the sensitivity and the specificity of carcinoembryonic antigen (cea) mrna and lung-specific x protein (lunx) mrna biomarkers in peripheral blood to detect lung cancer individually and simultaneously. met...

disulphide bridges in carcinoembryonic antigen (Thomas et af. , 1974). When carcinoembryonic antigen modified by treatment with 5.33rnhl-metaperiodate was hydrolysed in oxygen-free conditions and subjected to acid hydrolysis cystine was detected in a subsequent amino acid analysis, whereas only cysteic acid was obtained from carcinoembryonic antigen treated with 0.533 M-metaperiodate. Oxidative...

Primary and secondary tumour and bone marrow trephine biopsies from 20 patients with carcinomas were stained for carcinoembryonic antigen by the three stage immunoperoxidase method. Six marrow biopsies contained tumour deposits, five of which were positive for carcinoembryonic antigen. A further five marrow biopsies contained single carcinoembryonic antigen positive cells of uncertain origin. C...

We determined estrogen receptor protein and carcinoembryonic antigen in cytosols prepared from 189 human breast carcinoma tissues, 85 benign or normal breast biopsies, and 101 tissue specimens metastatic from breast carcinoma. Carcinoembryonic antigen was observed in 70% of the primary carcinomatous tissues, 15% of the benign or normal specimens, and 51% of the metastases. Ninety-six of the 189...
