OBJECTIVE
This study sought to evaluate prospectively the diagnostic potential of unenhanced and enhanced color Doppler and power Doppler for the differentiation of tumors and tumorlike lesions of the breast.
METHODS
Ninety-two patients with 110 tumors or tumorlike lesions of the breast were
Isolated caprine epididymal plasma glycoprotein "anti sticking factor" (ASF) interacts with caudal sperm surface in a D-galactose dependent manner. ASF acts as a Ca(2+) dependent soluble lectin principally activated in acidic pH. As a D-galactose specific lectin, it has a specific affinity for
We describr high-resolution chromatographic analysis for protein-bound sialic acid in serum, with use of a cerate oxidimetric detector. Values for sera from normal women averaged 680.5 mg/liter, with a coefficient of variation of 23%. Including data obtained by previously developed chromatographic
A 70-kDa galactose-specific lectin was purified from the tubers of Dioscorea opposita cv. nagaimo. The purification involved three chromatographic steps: anion exchange chromatography on a Q-Sepharose column, FPLC-anion exchange chromatography on a Mono Q column, and FPLC-gel filtration on a
The present study was designed to engineer surface-anchored and methotrexate loaded lipobrid nano-constructs for targeting breast cancer. Ligands (fucose, galactose and mannose) anchored lipobrid nano-constructs were used to compare and assess delivery efficiency in breast cancer cell lines as well
Gangliosides were isolated from the sera of recently diagnosed breast-cancer patients and from individuals who were apparently free of disease. Quantificative and qualitative analyses were carried out by 2-dimensional high-performance thin-layer chromatography and gas chromatography. The locations
A new methacrylic fructose glycomonomer is synthesized and copolymerized with N-isopropyl acrylamide by reversible addition fragmentation chain transfer (RAFT) poly-merization. By additional copolymerization of the analog mannose, glucose, and galactose glycomonomers, a set of glycopolymers is
Two forms of alpha 1-acid glycoprotein with common immunological determinants and almost identical amino acid compositions but different amounts of carbohydrate were isolated from liver metastases of primary colon, lung, and breast tumors by extraction with perchloric acid, gel filtration on
Galectin-3 is a 30-kDa galactose-binding protein member of the galectin family. Galectin-3 is involved in multiple intracellular and extracellular biological functions, e.g. interactions with laminin and with nucleic acids. This latter property is consistent with the presence of 3. serum-response
We have demonstrated that RRR-alpha-tocopheryl succinate (10 microg/mL vitamin E succinate (VES) treatment of estrogen receptor-negative MDA-MB-435 human breast cancer cells induces 9, 19, 51, and 72% apoptotic cells on days 1-4, respectively, after treatment, which involves transforming growth
The breast cancer-associated epitope (mammary serum antigen or MSA) defined by monoclonal antibody (Mab) 3E1.2 is a neuraminidase-sensitive carbohydrate expressed on MUC-1-encoded molecules. However, the reactivity of Mab 3E1.2 is also reduced by protease treatment of the mucin, which suggests that
Novel cationic dimethylaminopyridine derivatives of pentacyclic triterpenes were previously described to promote mitochondrial depolarization and cell death in breast and melanoma cell lines. The objective of this work was to further investigate in detail the mechanism of mitochondrial
Monoclonal antibody LICR-LON-M18 is a marker of normal human breast epithelial cell differentiation. The epitope recognized by LICR-LON-M18 is a prominent component of luminal plasma membranes of nonneoplastic resting and lactating human breast epithelial cells but is rarely expressed by human
Membrane binding sites for peanut lectin or peanut agglutinin (PNA) were investigated in the established mammary carcinoma cell lines MCF-7, 734-B, ZR-75.1 and BT-20. The determination of PNA binding sites was performed in a flow cytometer after staining with fluorescein(FITC)-labeled PNA. It
Mixtures of the T-47D human breast cancer cell line and normal human bone marrow cells were used for studying a new approach for purging epithelial tumor cells for autologous bone marrow transplantation (BMT) in breast cancer. Breast cancer cell line T-47D cells were shown to bind soybean agglutinin
