BACKGROUND The purpose of this study was to evaluate the feasibility of ultrasound-guided intratumoral indigo carmine injections for intraoperative localization of small head and neck tumors and to introduce our surgeon-performed technique. METHODS In total, 23 patients who had tumors ≤1.5 cm that were not palpable by 2 head and neck surgeons were enrolled in this prospective study. RESULTS...

The transformation of indole to indigo by microorganisms expressing styrene monooxygenase (SMO) has been studied. Styrene and indole are structurally very similar, and thus we looked at a variety of styrene-degrading strains for indole transformation to indigo. Two strains, Pseudomonas putida S12 and CA-3, gave a blue color on solid media when grown in the presence of indole. Indole induces its...

Distributed systems that consist of workstations connected by high performance interconnects ooer computational power comparable to moderate size parallel machines. Middleware like Distributed Shared Memory (DSM) or Distributed Shared Objects (DSO) attempts to improve the programmability of such hardware by presenting to application programmers interfaces similar to those ooered by shared memor...

In this paper, ZnBiSbO4 was synthesized by a solid-state reaction method for the first time. The structural and photocatalytic properties of ZnBiSbO4 had been characterized by X-ray diffraction, scanning electron microscopy, X-ray photoelectron spectroscopy, Fourier-transform infrared spectroscopy, transmission electron microscope and UV-visible spectrometer. ZnBiSbO4 crystallized with a pyroch...

The photophysics of indigo as well as of bispyrroleindigo, the basic chromophore of indigo, has been investigated with ab initio electronic-structure calculations. Vertical electronic excitation energies and excited-state potential-energy profiles have been calculated with the CASSCF, CASPT2 and CC2 methods. The calculations reveal that indigo and bispyrroleindigo undergo intramolecular single-...

Indigo is one of the most emblematic molecules for the color blue, and is believed in many cultures to be charged with unique talismanic properties. The vivid color and high stability of this dye have led to an almost mythical status, from the “tecklet” of the Hebrews (believed to be a mixture with Tyrian Purple), through the blue of Napoleon Bonaparte(s army uniforms, to its current applicatio...

Today, natural colorants are emerging globally due to the fact that they are safer and more environmentally-friendly. Natural dyes have been employed in dyeing Persian carpet piles for many years. In this study, the dried Achillea was used for dyeing wool yarns. The Iranian wool yarn was scoured, mordanted using Cu, Sn, Al salts and then dyed with different amounts of dried Achillea powder. Tag...

Celeribacter sp. strain TSPH2, a novel producer of indigo, was isolated from oil-contaminated sediment. We present here its genome sequence consisting of one circular chromosome (4 Mb) and one plasmid (0.15 Mb), with an overall G+C content of 60.9%. This strain contains oxygenase genes involved in indigo synthesis, such as flavin-containing monooxygenase.

Indigo carmine (sodium indigotindisulfonate) is a safe, biologically inactive blue dye routinely administered intravascularly during urologic and gynecologic procedures to localize the ureteral orifices and to identify severed ureters and fistulous communications. We report a case of hypotension, cardiac arrest, and cerebral ischemia after the administration of indigo carmine in a patient under...
