Nanoparticle tracking analysis (NTA) represents one essential technology to characterize diffusing nanoscale objects. Herein, uncovering dynamic processes and high-precision measurements requires tracks with thousands of frames reach high statistical significance, ideally at frame rates. Optical fibers nanochannels are used for NTA, successfully demonstrating acquisition trajectories fast diffu...

In this study we have shown that Quercus infectoria attenuates FeNTA induced renal oxidative stress, hyperproliferative response and renal carcinogenesis in rats. Fe-NTA promoted DEN (N-diethyl nitrosamine) initiated renal carcinogenesis by increasing the percentage incidence of tumors and induces early tumor markers viz. ornithine decarboxylase (ODC) level and PCNA expression. FeNTA (9 mg Fe/k...

The studies on removal of Vanadium were conducted using Granulated Activated Carbon (GAC) in combination with Chelating agents. Ethylene di-amine Tetra Acetic Acid (EDTA) and Nitrilo Tri Acetic Acid (NTA) at 25oC. The adsorption Efficiency was studied in the pH range of 2-8. The results reveals that Langmuir and Freundlich isotherms are followed during adsorption process with the chelating agen...

We report a generic approach for targeting proteins into micropatterns by in situ laser lithography. To this end, we have designed a photocleavable oligohistidine peptide for caging tris(nitrilo triacetic acid) (tris-NTA) groups on surfaces by multivalent interactions. Local photofragmentation of the peptide by UV illumination through a photomask or by a confocal laser beam uncages tris-NTA, th...

Combinations of nitrilotriacetic acid (NTA) derivatives with technetium 99mTc are known as convenient contrasting compounds used in nuclear medicine. Because of low resolution of this method, as well as necessity for using radioactive substances we have suggested new combinations of NTA aromatic derivatives with Gd(III). The aim of the undertaken study was to obtain contrasting compounds showin...

Interaction between apo-transferrin and several iron(III) chelates has been investigated in terms of the capillary electrophoresis method. Based on the results, it has been clarified that (i) a binuclear iron(III) unit with an oxo-bridge is necessary for the facile transfer of an iron atom from the iron(III) chelate to apo-transferrin, and (ii) the renal proximal tubular injuries by Fe(III)-nit...

This article seeks to identify and discuss the impact of Nina Olson, in her role as National Taxpayer Advocate (NTA), on low-income taxpayer clinics (LITCs). The discusses background Ms. Olson including advocacy that led grant funding for LITCs before she began administering funds NTA. accomplishments with respect are discussed six separate topic areas: Changes Clinic Structure; Pushing Actions...
