25-NBD-cholesterol 25-[ N -[(7-nitrobenz-2-oxa-1,3-diazol-4-yl)methyl]amino]27-norcholesterol 5-HT 1A receptor 5-Hydroxytryptamine-1A receptor 5-HT 1A R-EYFP 5-Hydroxytryptamine-1A receptor tagged to enhanced yellow fl uorescent protein DiIC 18 (3) 1,1′-Dioctadecyl-3,3,3′,3′,-tetramethylindocarbocyanine perchlorate EYFP Enhanced yellow fl uorescent protein FAST DiI 1,1′-Dilinoleyl-3,3,3′,3′,-te...

The spectrophotometric determination of Cu(II) with an anthraquinone derivative (Alizarin Red S) has been investigated. The experimental conditions, such as the pH of the sample and concentration of ligand, were optimized. This method is simple and sensitive for determination of Cu(II) ion. The interfering effects of diverse ions were investigated. Copper ion was determined by measuring the abs...

A growth experiment was conducted with juvenile fringed flounder (Etropus crossotus) from North Inlet (South Carolina, USA) to provide information on the growth of a small, shortlived flatfish with a subtropical and tropical distribution. The fringed flounder has a maximum life span of 1.5 y and its long spawning period from March through October complicates the determination of growth rates ba...

Cr (III) removal from aqueous solutions by sorption in a fixed bed column filled with alizarin S impregnated hemp fibers has been studied. The effect of the initial metal ion concentration on the Cr (III) sorption process was investigated and the experimental breakthrough curves were obtained. The breakthrough time and saturation time decreased from 110 min to 80 min and from 300 min to 160 min...

The effect of several surfactants on the formation of the fluorescent ternary complex oxalate-Alizarin Red S-zirconium(IV) has been studied. In weakly acidic medium and in the presence of cationic surfactants, such as cetylpyridinium chloride, total complex formation is achieved, whereas in aqueous medium or in the presence of non-cationic micelles no significant changes are obtained in compari...

This paper describes an image analysis technique for automated estimation of the percentages of epithelium and stroma in (tumor) tissue. The program is evaluated on ovarian tumors of the serous, mucinous, and endometrioid type. From standard paraffin sections, stained with pararosanilin Feulgen and naphthol yellow, a blue-yellow image pair was recorded. The blue image was used for the determina...

Schizothorax wangchiachii is a key fish species in the stock enhancement program of the Yalong River hydropower project, China. Alizarin red S (ARS) was used to mark large numbers of juvenile S. wangchiachii in the Jinping Hatchery and later used to evaluate stock enhancement in the Jinping area of the Yalong River. In a small-scale pilot study, 7,000 juveniles of the 2014 cohort were successfu...

Because danthron, though carcinogenic, does not seem to be genotoxic, it and 8 other hydroxyanthraquinones were comparatively investigated for activities associated with tumor promotion, such as stimulation of cell proliferation and enhancement of malignant transformation. The in vivo treatment of primary rat hepatocytes with danthron, aloe-emodin, chrysophanol, and rhein resulted in a 2-3-fold...

Cyanine–aryl acetylene conjugates (pink) accumulate in the mitochondria of cancer cells, where elevated pH and reactive oxygen species (white) levels allow formation thiyl radicals (yellow glowing pin first arrow) from thiols (dark yellow pin). The activation enables radical thiol-yne coupling biomolecules to dye–alkyne conjugate (second arrow). This represents a powerful tool for selective tar...

The yellow dwarf viruses (YDVs) of the Luteoviridae family represent the most widespread group of cereal viruses worldwide. They include the Barley yellow dwarf viruses (BYDVs) of genus Luteovirus, the Cereal yellow dwarf viruses (CYDVs) and Wheat yellow dwarf virus (WYDV) of genus Polerovirus. All of these viruses are obligately aphid transmitted and phloem-limited. The first described YDVs (i...
