We report on the use of mesoporous silica microparticles (μPs) functionalized with quarternary amino groups for the isolation of platinum and palladium tetrachloro complexes from aqueous road dust digests. The μPs have a size ranging from 450 to 850 nm and are suspended directly in the aqueous digests, upon which the anionic Pt and Pd complexes are retained on the cationic surface. Subsequently...

Cisplatin derivatives can form various types of DNA lesions (DNA-Pt) and trigger pleiotropic DNA damage responses. Here, we report a strategy to visualize DNA-Pt with high resolution, taking advantage of a novel azide-containing derivative of cisplatin we named APPA, a cellular pre-extraction protocol and the labeling of DNA-Pt by means of click chemistry in cells. Our investigation revealed th...

The first part of this paper presents a survey of the literature on automatic handwritten signature verification systems using binary or graylevel images, and focuses primarily on preprocessing techniques, feature or primitive extraction methods, comparison processes, and performance evaluation. With these previous studies in mind, we propose, in the second part of this paper, an image-understa...

The extraction of renewable energy resources particularly from earth abundant materials has always been a matter of significance in industrial products. Herein, we report a novel simultaneous extraction of nano-silicon with activated carbons (nano-Si@ACs) from rice husk (RH) by chemical activation method. As-extracted nano-Si@ACs is then used as an energy harvesting materials in counter electro...

the binding energy and thermodynamic parameters of cis- platinum di ammino chlorine (cis-[pt(nh3)2cl]+) and trans- platinum di ammino chlorine (trans- [pt(nh3)2cl]+) complexes withguanine has been studied by density functional theory (dft) calculations in water. the bindingenergies (ebin) of cis- and trans-[pt(nh3)2clg]+ are calculated to be 79.38 kcal/mol and 74.98kcal/mol, respectively. the b...

Abstract We developed a novel method for production of no-carrier-added (n.c.a.) [ 188, 189, 191 Pt]Pt II Cl 4 2− from an Ir target material, and then synthesized n.c.a. [*Pt]cis-[Pt 2 (NH 3 ) ] ([*Pt]cisplatin) [*Pt]Pt . was prepared as synthetic precursor *Pt complex by combination resin extraction anion-exchange chromatography after the selective reduction IV 6 with ascorbic acid. The ligand...

OBJECTIVES We investigated incidence and risk factors for postextraction bleeding in patients receiving warfarin and those not receiving anticoagulation therapy. DESIGN Cross-sectional, multicentre, observational study. SETTING 26 hospitals where an oral surgeon is available. PARTICIPANTS Data on 2817 teeth (from 496 patients receiving warfarin, 2321 patients not receiving warfarin; mean ...

We measured the in situ polarization-dependent X-ray absorption fine structure of platinum nanoparticles (PtNPs) deposited on a flat highly oriented pyrolytic graphite (HOPG) substrate under electrochemical conditions using a back-side illumination method. In this method, the thin HOPG substrate with PtNPs deposited on one side was used as a window for incident and fluorescent X-rays, as well a...
