We have prepared and characterized a SnO2-decorated Pt-Sn(oxidized)/C cathode catalyst in a polymer electrolyte fuel cell (PEFC). Oxygen reduction reaction (ORR) performance of Pt/C (TEC10E50E) remained almost unchanged or even tended to reduce in repeated I-V load cycles, whereas the I-V load performance of the Pt-Sn(oxidized)/C prepared by controlled oxidation of a Pt-Sn alloy/C sample with t...

Platinum-based anticancer drugs are chemotherapeutic agents to treat cancer. Carboplatin (cis diammine cyclobutane dicarboxylate platinum (II)) is a second generation drug that has less toxic than cisplatin, allowing for high dosages. In the first stage, 1,3-Cyclobutane dicarboxylic acid, a key intermediate for the preparation of carboplatin, have been synthesized in good yields using diffe...

To assess survival outcomes in a retrospective study, recurrent epithelial ovarian cancer patients were divided into three groups according to the platinum free interval as follows: platinum refractory that included the patients with tumor progression during treatment; platinum resistant and platinum sensitive that included the patients with tumor progression less than or more than six months, ...

BACKGROUND The majority of women with ovarian cancer develop recurrent disease. For patients with a platinum-free interval of >6 months, platinum-based chemotherapy is a treatment of choice. The benefit of platinum-based combination chemotherapy in randomized trials varies, and a meta-analysis was carried out to gain more secure information on the size of the benefit of this treatment. MATERI...

We have examined a panel of 12 unrelated human ovarian cancer cell lines derived from patients who were either untreated or treated with platinum-based chemotherapy to determine whether a relationship is present between cisplatin sensitivity and: (a) cellular platinum accumulation; (b) glutathione levels; (c) platinum-DNA adduct formation; (d) platinum-DNA adduct removal; and (e) platinum-DNA d...

OBJECTIVES To review the available systemic treatments for women with recurrent ovarian cancer. METHODS A literature review was conducted for recurrent ovarian cancer articles in English, including randomized trials, Phase II trials, or reviews. RESULTS We discuss the efficacy and toxicity outcomes associated with systemic therapy for platinum-sensitive and platinum-resistant ovarian cancer...

OBJECTIVE The objective of this study was to compare hospital costs per treatment cycle (HCTC) for nonchemotherapy drugs and nondrug care associated with platinum-based doublets in the first-line setting for advanced nonsquamous non-small-cell lung cancer (AdvNS-NSCLC) in Chinese patients. METHODS Patients receiving platinum-based doublets in the first-line setting for AdvNS-NSCLC from 2010 t...

The metal resistant bacterium Cupriavidus metallidurans CH34, challenged with aqueous platinous and platinic chloride, rapidly immobilized platinum. XANES/EXAFS analysis of these reaction systems demonstrated that platinum binding shifted from chloride to carboxyl functional groups within the bacteria. Pt(IV) was more toxic than Pt(II), presumably due to the oxidative stress imparted by the pla...
