Single-Cell Electroporation of Xenopus Tadpole Tectal Neurons

01-Sep-2011 | Liu, X. F., Haas, K., CSH Protocols, 2011

INTRODUCTION Single-cell electroporation (SCE) is a versatile technique for delivering electrically charged macromolecules, including DNA, RNA, synthetic oligonucleotides, peptides, dyes, and drugs, to individual cells within intact tissues. Here, we describe methods for SCE of single tectal ...


A Convenient Synthesis of Cyclopentadienylgallium – The Awakening of a Sleeping Beauty in Organometallic Chemistry

01-Aug-2011 | Christian Schenk; Ralf Köppe; Hansgeorg Schnöckel; Andreas Schnepf, European Journal of Inorganic Chemistry, 2011

Abstract Solid “GaI” reacts with NaCp to yield (η5‐cyclopentadienyl)gallium (GaCp) (1). During the synthesis the side product, CpGa→GaCp2I (2), with a rare gallium–gallium donor–acceptor bond could be isolated. The reaction of 1 with B(C6F5)3 affords CpGa→B(C6F5)3 (4). The molecular structures ...


Energy‐dispersive diffraction stress analysis under laboratory and synchrotron conditions: a comparative study

01-Feb-2011 | Ch. Genzel; S. Krahmer; M. Klaus; I. A. Denks, Journal of Applied Crystallography, 2011

For a feasibility study of energy‐dispersive residual stress analysis under laboratory conditions, an X‐ray diffractometer that has been operated so far in the angle dispersive diffraction mode was equipped with a commercial tungsten tube and an energy‐dispersive solid‐state germanium detector. ...


Enhancing the lateral-flow immunoassay for viral detection using an aqueous two-phase micellar system

23-Sep-2010 | Foad Mashayekhi, Ricky Y. T. Chiu, Alexander M. Le, Felix C. Chao, Benjamin M. Wu, Daniel T. Kamei, Analytical and Bioanalytical Chemistry, 2010

Availability of a rapid, accurate, and reliable point-of-care (POC) device for detection of infectious agents and pandemic pathogens, such as swine-origin influenza A (H1N1) virus, is crucial for effective patient management and outbreak prevention. Due to its ease of use, rapid processing, and ...


The study of vapour phase hydrogen peroxide decontamination process as a potential method for degradation of organic pollutants

01-Sep-2010 | Švrček, Jiří; Marhoul, Antonín; Kačer, Petr; Kuzma, Marek; Pánek, Libor ..., Journal of Chemical Technology & Biotechnology, 2010

BACKGROUND: The work is focused on the application of vapour phase hydrogen peroxide (VPHP) as a highly promising and effective decontamination technique. The aim of this work was to assess the use of this validated technique for the removal of chemicals from contaminated surfaces and examine the ...


Enantiomerically Pure trans-β-Lactams from α-Amino Acids via Compact Fluorescent Light (CFL) Continuous-Flow Photolysis

11-Aug-2010 | Yvette S. Mimieux Vaske; Maximillian E. Mahoney; Joseph P. Konopelski; David L. Rogow; William J. McDonald, Journal of the American Chemical Society, 2010

Photolysis of α-diazo-N-methoxy-N-methyl (Weinreb) β-ketoamides derived from enantiomerically pure (EP) α-amino acids affords the corresponding EP β-lactams via an intramolecular Wolff rearrangement. The photochemistry is promoted with either standard UV irradiation or through the use of a 100 W ...


The activity of cobalt aluminum catalyst in reaction of nitrous oxide decomposition

24-Jul-2010 | T. P. Gaidei, N. Pillet, V. N. Sadov, M. E. Strukova, S. M. Filatov, E. S. Khaustova, N. T. Yaroshenko, Russian Journal of Applied Chemistry, 2010

Data of activity of cobalt aluminum catalysts with various content of active component in reaction of nitrous oxide decomposition obtained both on laboratory equipment and model catalytic reactor are presented.


Determination of arsenic (III) and arsenic (V) in freshwater biological samples from Thailand by solvent extraction and neutron activation

05-Jul-2010 | R. Zwicker, B. M. Zwicker, S. Laoharojanaphand, A. Chatt, Journal of Radioanalytical and Nuclear Chemistry, 2010

Neutron activation analysis (NAA) methods were employed for the determination of total arsenic, and water soluble As(III) and As(V) compounds in freshwater fish/shellfish and plant samples from Southern Thailand. Total arsenic concentrations varied from 0.05 to 425 mg kg−1. Water soluble arsenic ...
