The presence or absence of an oestrogen receptor-related antigen in breast tumours has been examined histochemically using a monoclonal antibody ('D59 Coffer & King, 1981). In frozen sections, fixed either by the method of Tamura et al. (1980) or in methanol, staining was apparent in 14/24 (58%) and 22/26 (85%) of the breast cancers respectively. In paraffin sections fixed in ethanol, staining ...

متن کاملTriphenyl(pyrrolidine-1-carbodithioato-κS)tin(IV)
In the title compound, [Sn(C6H5)3(C5H8NS2)], the Sn(IV) atom adopts a distorted SnC3S tetra-hedral coordination geometry [spread of bond angles = 94.43 (7)-120.74 (7)°]. A short intra-molecular Sn⋯S contact [3.0270 (9) Å] occurs and two intra-molecular C-H⋯S inter-actions help to establish the conformation. Three of the methyl-ene groups of the pyrrolidine-1-carbodi-thio-ate ligand are disorder...
متن کاملTricyclohexyl(piperidine-1-dithiocarboxylato-κS)tin(IV)
In the title compound, [Sn(C(6)H(11))(3)(C(6)H(10)NS(2))], the Sn(IV) atom is tetra-coordinated by three C atoms from cyclo-hexyl groups and one S atom from a piperidine-dithio-carboxyl-ate anion. The coordination geometry is distorted tetra-hedral, with Sn-C bond lengths in the range 2.133 (6)-2.188 (6) Å and with an Sn-S bond length of 2.4516 (19) Å. The nonbonded S atom of the piperidine-dit...
متن کاملAudit of diabetes in Perak outpatient departments.
Adequacy of diabetic management in 5 Perak outpatient departments was studied in April 1996. Two hundred diabetic patients' records were analysed. All doctors and 100 patients answered questionnaires on diabetes. Fifty five percent of doctors had adequate knowledge. Patients' knowledge varied between centres (13% to 80% adequacy). Most records had insufficient data to determine adequacy of earl...
