Isolation and characterization of microcystins from a river nile strain of Oscillatoria tenuis Agardh ex Gomont.
This is the first report of a toxic O. tenuis, strain E6, one which produces a fully methylated MCYST,MCYST-LR and a new L-homoarginine containing MCY ST, MCyST-LHArg. Expand
Purification of paired helical filament tau and normal tau from human brain tissue.
This chapter describes a procedure to effectively purify PHF–tau and soluble normal tau preparations from human brain. Expand
Repression of ATR pathway by miR-185 enhances radiation-induced apoptosis and proliferation inhibition
The findings indicate a previously unreported regulatory mechanism for ATR expression mediated by miR-185 and shed light on the potential application of miRNAs both as direct cancer therapeutics and as tools to sensitize tumor cells to radiotherapy. Expand
The antioxidant activities of natural sweeteners, mogrosides, from fruits of Siraitia grosvenori
The results showed that these sweet glycosides, having cucurbitane triterpenoid aglycon, exhibited significant inhibitory effects on reactive oxygen species (, H2O2 and •OH) and DNA oxidative damage. Expand
FastJoin, an improved neighbor-joining algorithm.
A new method of reconstructing phylogenetic trees, FastJoin, was proposed, and experiments with sets of data showed that this new neighbor-joining algorithm yields a significant speed-up compared to classic neighbor- joining, showing empirically that FastJoin is superior to almost all other neighbor-joined implementations.

Development of an amperometric biosensor for the determination of phenolic compounds in reversed micelles.
The possibilities of amperometric enzyme electrodes in reversed micellar systems for the determination of phenol, 4-chloro-3-methylphenol and 2,4-dimethylphenol are illustrated and the effect of the analyte solubility in water upon the analytical performance of the electrode was explored. Expand
Determination of trace thorium using catalytic-adsorptive stripping voltammetry of the thorium-cupferron complex.
A sensitive stripping voltammetric procedure for trace measurement of thorium, based on the catalytic-adsorptive peak of the thorium-cupferron complex, is reported, offering improved sensitivity over a previous stripping scheme for thorium. Expand
Improved bioethanol productivity through gas flow rate-driven self-cycling fermentation
Significant improved productivity is demonstrated through application of an advanced fermentation approach, named self-cycling fermentation (SCF), for cellulosic ethanol production, which could help reduce production costs for the cellulOSic ethanol industry through improved productivity and automated operation.

Structural and Optical Properties of ZnO Nanowires Doped with Magnesium
ZnO nanowires doped with Mg have been successfully prepared on Au-coated Si (111) substrates using chemical vapor deposition method with a mixture of ZnO, Mg, and activated carbon powders asExpand
Fabrication of DABCO functionalized poly(ionic liquids): Vital role of ferric oxides in the formation of mesoporous structure and used as highly efficient and recyclable catalysts for multi-component
Abstract The preparation of well-defined porous materials as carriers is critically fundamental for the design of heterogeneous catalysts. In this study, 1,4-Diazabicyclo[2.2.2]octane (DABCO) basedExpand
