A series of platinium(II) complexes of formula [Pt2L4(berenil)2]Cl4.4HCl.2H2O where L is piperidine (1), 4-picoline (2), 3-picoline (3) or isopropylamine (4) was prepared and their cytotoxicity have been tested against the growth of human breast cancer cells. Evaluation of the cytotoxicity of these compounds employing a MTT assay and inhibition of [3H]thymidine incorporation into DNA in both MD...

Hybrid nanocomposites of binary Pt-Ru/Polyaniline were prepared by oxidative polymerization of aniline andformation Pt and Ru nanoparticles. The polymerization of aniline was carried out in the presence of Potassiumhexa cyano Platinate (IV) and Ruthenium (III) nitrosyl nitrate as oxidizing agents. During the reaction anilinemonomers undergo oxidation and form polyaniline (PANi) whereas the redu...

BACKGROUND Predictor factors determining complete response to treatment are still not clearly defined. We aimed to evaluate clinicopathological features, risk factors, treatment responses, and survival analysis of patient with advanced nonseminomatous GCTs (NSGCTs). MATERIALS AND METHODS Between November 1999 and September 2011, 140 patients with stage II and III NSGCTs were referred to our i...

Introduction Direct methanol fuel cells are very important as a clean, low cost and portable power source because of several environmental problems in traditional energy producing systems. Compared to the hydrogen fueled PEMFCs, direct methanol PEMFCs are more compact and can be used in power portable electric devices. Platinum is the most active electro-catalyst for the electro-oxidation of me...

BACKGROUND Carotid-cavernous fistulas are abnormal communications between carotid arteries or their branches and the cavernous system caused mostly by trauma. Posttraumatic fistulas represent 70% of all carotid-cavernous fistulas and they are mostly high-flow shunts (type A). This type gives characteristic eye symptoms. CASE REPORT This paper presents a 44-year old male patient with carotid-c...

an on-line uv-hplc / apci-ms (atmospheric pressure chemical ionization) tandem by a platinium c18 column with an isocratic solvent system after optimizing was applied to the separation and the identification of different carotenoids including astaxanthin, canthaxanthin, apocarotenoic ester, torularhodin and beta carotene. this method was used to identify particular carotenoids produced by newly...
