A basic finding in developmental neurophysiology is that some areas of the cortex cortical areas will reorganize following a period of stimulus deprivation. In this review, we discuss mainly electroencephalography (EEG) studies of normal and deprivation-induced abnormal development of the central auditory pathways in children and in animal models. We(More)
A flow cytometric technique has been established for accurately quantitating the cell surface density of MHC antigens and the percentage of cells expressing MHC antigens in 38 colorectal tumours. Thirty-four percent of tumours were partially or completely negative for HLA-ABC antigen expression. Although the quantity of HLA-ABC antigens varied widely, there(More)
I. Background 1. Proteins are synthesized as chains of amino acid residues joined in peptide (NHCO) linkage, ...-CONH-HCR 1-CONH-HCR 2-... 1.a, There are 20 different amino acids (20 R groups). 1.b, The newly synthesized protein is unfolded (U). A protein does not become biologically active until it folds into a specific 3D structure. The product of folding(More)
Monoclonal antibody against an osteogenic-sarcoma cell line (791T) was prepared by production and cloning of a somatic-cell hybrid between the mouse myeloma P3-NS1 and spleen cells from 791T-immunized mice. Three clones of hybridoma producing antibody against 791T, as detected by 125I-labelled Protein A binding, were tested against a range of normal and(More)
Urinary mucins which express determinants for the anti-breast carcinoma monoclonal antibody, NCRC-11 (IgM), closely resemble the mammary mucins found in milk fat globules and carcinomas. An IgG3 monoclonal antibody, C595, was prepared against urinary mucins isolated on a NCRC-11 antibody affinity column, and this 'second generation' antibody was shown to(More)
Cells from two adenocarcinomas, an adenoma and a metastatic node were isolated in soft agar. Expression of antigens, CEA, Y haptenic blood group and 791T-p72, defined by a range of candidate antibodies for tumour targeting was assessed. All of the cells expressed low levels of CEA but high levels of the Y haptenic blood group antigen although there was(More)
The anti-mitotic drug vindesine was coupled chemically to a monoclonal antibody raised originally against the human osteogenic sarcoma cell line, 791T. The cytotoxicity of the conjugate in vitro was tested, in comparison with free vindesine, against sarcoma 791T and other antigenically cross-reactive osteogenic sarcoma-cell lines, and also against tumour(More)
Immunocytochemical staining with monoclonal antibody NCRC 11 of formalin fixed paraffin embedded tumour tissue has been studied in 444 cases of primary breast cancer with a minimum follow period of 6 years. The relationship between extent of staining, assessed on a four point scale, and patient survival has been confirmed. There are significant(More)
NCRC-11 is an IgM monoclonal antibody which defines an antigen found in most epithelial malignancies. The antigen has previously been shown to be a high mol. wt. glycoprotein (greater than 400,000) and in this study, antigen preparations were isolated by immunoadsorbent chromatography from ovarian mucinous and ovarian serous cyst adenocarcinoma and from(More)
