    Platinum-based drugs cisplatin, carboplatin and oxaliplatin are widely used in the therapy of human neoplasms. Their clinical success is, however, limited due to severe side effects and intrinsic or acquired resistance to the treatment. Much effort has been put into the development of new platinum anticancer complexes, but none of them has

    22/03/2016· Breast cancer associated (BRCA) genes are critical for DNA repair. Mutations in BRCA1 and BRCA2 (BRCAm) result in loss of these repair mechanisms and potential carcinogenesis. Germline BRCAm are common in ovarian carcinomas, particularly in platinum-sensitive disease. The increased prevalence of BRCAm in platinum-sensitive disease is likely due to enhanced responsiveness to platinum

  • Surface characteristics and flotation behaviour of

    Research on the flotation behaviour of platinum group minerals (PGM) has mainly focused on the flotation of base metal sulphides because of their association with the PGMs and due to the assumption that the PGMs would respond similarly to such sulphides in their flotation behaviour.

  • Investigations into the Recovery of Platinum Group

    In the flotation of platinum group minerals (PGMs) it has generally been assumed that they will behave similarly to base metal sulfides and thus sulfide reagent regimes are generally used in such flotation plants. However the tellurides and arsenides of platinum and palladium contribute about 50% of the PGMs present in the Platreef ore, located in the northern limb of the Bushveld Complex of
