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...

Ovarian cancer is characterized by an increase in cellular energy metabolism, which is predominantly satisfied by glucose and glutamine. Targeting metabolic pathways is an attractive approach to enhance the therapeutic effectiveness and to potentially overcome drug resistance in ovarian cancer. In platinum-sensitive ovarian cancer cell lines the metabolism of both, glucose and glutamine was ini...

Two dimensional (2D) gamma-boron (γ-B28) thin films have been firstly reported by the experiments of the chemical vapor deposition in the latest study. However, their mechanical properties are still not clear. Here we predict the superhigh moduli (785 ± 42 GPa at 300 K) and the tension-induced phase transition of monolayer γ-B28 along a zigzag direction for large deformations at finite temperat...

To improve graphene-based multifunctional devices at nanoscale, a stepwise and controllable fabrication procedure must be elucidated. Here, a series of structural transition of bismuth (Bi) adatoms, adsorbed on monolayer epitaxial graphene (MEG), is explored at room temperature. Bi adatoms undergo a structural transition from one-dimensional (1D) linear structures to two-dimensional (2D) triang...

a-Amino Acid Esters, Peptide Esters, Platinum(IV) Complexes, "N NMR Spectra, Pt NMR Spectra The platinum(IV) complexes PtX4L2 (X = Cl, Br; 2 X = oxalate; L = glyOEt, glyglyOEt, gly-cleuOEt; 2 L = metOEt) have been obtained by oxidative addition of halogenes to platinum(II) compounds PtX2L2A high field shift of <3N (—50 ppm) is observed for the coordinated amino acid ligand of various platinum c...

abstract background: hyperthermia (also called thermal therapy or thermotherapy) is a type of cancer treatment in which body tissue is exposed to high temperatures (up to 113°f). research has shown that high temperatures can damage and kill cancer cells, usually with minimal injury to normal tissues.  for many years, biologists have investigated cancer by using monolayer cell culture. it is bec...

OBJECTIVE Primary platinum-resistant epithelial ovarian cancer (EOC) is an area of unmet medical need. There is limited evidence from small studies that platinum-based combinations can overcome "resistance" in a proportion of patients. We investigated the efficacy and toxicity of platinum-based combination chemotherapy in the platinum-resistant and platinum-refractory setting. METHODS Epirubi...

the development of metal-based therapeutics. Cisplatin is one platinum complex and is widely used in treatments for cancer. Shimizu and Tsuji established a method of preparing colloidal platinum particles, whose average size is 2 nm, by ethanol reduction of H2PtCl6 in the absence of protective agents such as hydrophilic polymers. They used only the chemicals permitted to food additives such as ...
