Patients with longstanding ulcerative colitis have an increased risk of colorectal cancer. Mouse models for colitis-associated tumors are indispensable for the development of novel strategies for prevention and intervention, as well as an improved understanding of the mechanisms underlying tumor formation. The present study examined whether stereomicroscopic observations with dye-application were able to detect and discriminate tumors in a colitis-associated tumor model in mice. Colonic tumors were induced in C57BL/6 mice by 15 cycles of treatment with dextran sulfate sodium (DSS) in drinking water...

Ultraviolet-visible (UV-vis) and fluorescence spectroscopy have been used to characterize the polyelectrolyte complexes (PECs) formed when potassium indigo tetrasulfonate (ITS) interacts with poly diallydimethylammonium chloride (PDADMAC) through columbic attraction in the presence of the reducing agent sodium bisulfite, NaHSO3. The PDADMAC facilitates both the reduction of the ITS and the stabilization of the reduced state of the ITS in an atmospheric oxygen environment. Dilutions of the dye solution show that the PEC is stable to dilutions of at least 1 to 1000...

Cytochrome P450cam (a camphor hydroxylase) from the soil bacterium Pseudomonas putida shows potential importance in environmental applications such as the degradation of chlorinated organic pollutants. Seven P450cam mutants generated from Sequence Saturation Mutagenesis (SeSaM) and isolated by selection on minimal media with either 3-chloroindole or the insecticide endosulfan were studied for their ability to oxidize of 3-chloroindole to isatin. The wild-type enzyme did not accept 3-chloroindole as a substrate...

Ultrafast vibrational relaxation and structural dynamics of indigo carmine in dimethylsulfoxide were examined using femtosecond pump-probe infrared and two-dimensional infrared (2D IR) spectroscopies. Using the intramolecularly hydrogen-bonded C=O and delocalized C=C stretching modes as infrared probes, local structural and dynamical variations of this blue dye molecule were observed. Energy relaxation of vibrationally excited C=O stretching mode was found to occur through covalent bond to the delocalized aromatic vibrational modes on the time scale of a few picoseconds or less...

Obligately alkaliphilic, indigo-reducing strains, designated Bps-1T, Bps-2 and Bps-3, were isolated from an indigo fermentation liquor used for dyeing, which was produced from sukumo (composted Polygonum indigo leaves) obtained from a craft centre in Data City, Hokkaido, Japan, by using medium containing cellulase-treated sukumo. The 16S rRNA gene sequence phylogeny suggested that Bps-1T has a distinctive position among the alkaliphilic species of the genus Bacillus, with its closest neighbours being Bacillus pseudofirmus DSM 8715T, Bacillus lindianensis DSM 26864T and Bacillus alcalophilus DSM 485T (96...

BACKGROUND: Increasing physical activity (PA) effectively in those who are inactive is challenging. For those who have subjective memory complaints (SMC) or mild cognitive impairment (MCI) this is a greater challenge necessitating the need for more engaging and innovative approaches. The primary aim of this trial is to determine whether a home-based 6-month PA intervention with individual goal-setting and peer mentors (GM-PA) can significantly increase PA levels in insufficiently active older adults at increased risk of developing Alzheimer's disease (AD)...

Many methods have been developed to measure the antioxidant capacity of foods under non physiological-relevant conditions. In this study, three methods (TEACOH, GEACRED and TEACAAPH) are developed to measure antioxidant capacity at physiological pH, using indigo carmine as a redox dye. TEACOH and TEACAAPH determine foodstuffs' scavenging capacity against hydroxyl (OH) and AAPH radicals, while the third method measures the global reducing capacity of the sample. The results obtained for commercial teas, commercial beverages containing tea as the main ingredient and different solid foods (spinach, onion, salami, etc...

BACKGROUND: Indigo naturalis is a Traditional Chinese Medicine (TCM) ingredient long-recognized as a therapy for several inflammatory conditions, including psoriasis. However, its mechanism is unknown due to lack of knowledge about the responsible chemical entity. We took a different approach to this challenge by investigating the molecular profile of Indigo naturalis treatment and impacted pathways. METHODS: A randomized, double-blind, placebo-controlled clinical study was conducted using Indigo naturalis as topical monotherapy to treat moderate plaque psoriasis in a Chinese cohort (n = 24)...

  The present report describes the removal of indigo carmine dye from water via adsorption on ZnAl-r hydrotalcite. Two grades of clay based on Zn/Al molar ratios of 3 and 4, uncalcined and calcined, were used. The adsorbents characterization using X-ray diffraction (XRD), Fourier transform infrared (FTIR), differential thermal and thermogravimetric analysis (DTA and TGA, respectively) revealed a layered structure for the hydrotalcite clays, whereas their calcination favored the formation of ZnO and ZnAl2O4 mixed metal oxides...

A novel protocol for the synthesis of unsymmetrical indigo-like (E)-α-amino enaminones by rhodium-catalyzed transformations of isatins with 1-tosyl-1,2,3-triazoles has been developed. A plausible reaction mechanism is proposed to account for the formation of structurally important unsymmetrical indigo analogues, which represents a new strategy for C-C bond formation based on the transformations of secondary amides and rhodium azavinylcarbenes.

Self-sufficient CYP102As possess outstanding hydroxylating activity to fatty acids such as myristic acid. Other CYP102 subfamily members share substrate specificity of CYP102As, but, occasionally, unusual characteristics of its own subfamily have been found. In this study, only one self-sufficient cytochrome P450 from Streptomyces cattleya was renamed from CYP102A_scat to CYP102G4, purified and characterized. UV-Vis spectrometry pattern, FAD/FMN analysis, and protein sequence comparison among CYP102s have shown that CYP102 from Streptomyces cattleya belongs to CYP102G subfamily...

Sessile serrated adenomas/polyps (SSA/Ps) have attracted increasing attention since their risk of developing into cancer was clarified [1]. Difficulty in determining their margins causes incomplete resection [2]. Although narrow-band imaging (NBI) and other advanced imaging systems are reportedly useful in evaluating these polyps [3, 4].

The bioremediation and electro-oxidation (EO) processes are included among the most promising cleaning and decontamination mechanisms of water. The efficiency of bioremediation is dictated by the biological actuator for a specific substrate, its suitable immobilization and all involved biochemical concepts. The EO performance is defined by the anode efficiency to perform the complete mineralization of target compounds and is highlighted by the low or null use of reagent. Recently, the combination of both technologies has been proposed...

Assembled structures of dyes have great influence on their coloring function. For example, metal ions added in the dyeing process are known to prevent fading of color. Thus, we have investigated the influence of an addition of copper(II) ion on the surface structure of alkyl-derivatized indigo. Scanning tunneling microscope (STM) analysis revealed that the copper(II) complexes of indigo formed orderly lamellar structures on a HOPG substrate. These lamellar structures of the complexes are found to be more stable than those of alkyl-derivatized indigos alone...

Polygonum tinctorium Lour (indigo plant) has been regarded as a useful medicinal plant for traditional herbal medicine. The polyphenolic fraction of indigo leaves exhibited anti-inflammatory activities as determined by the suppressed synthesis of nitric oxide (NO) in cultured RAW264 macrophage cells. The acid hydrolysate of the fraction showed much more potent effect than the unhydrolyzed one. In sharp contrast, those fractions of indigo stems had almost no effect. 3,5,4'-Trihydroxy-6,7-methylenedioxyflavone (TMF)-O-glycosides and tryptanthrin were detected exclusively in the extracts of the leaves...

Mid-trimester preterm premature rupture of membranes (PPROM), defined as rupture of fetal membranes prior to 28 weeks of gestation, complicates approximately 0.4%-0.7% of all pregnancies. This condition is associated with a very high neonatal mortality rate as well as an increased risk of long- and short-term severe neonatal morbidity. The causes of the mid-trimester PPROM are multifactorial. Altered membrane morphology including marked swelling and disruption of the collagen network which is seen with PPROM can be triggered by bacterial products or/and pro-inflammatory cytokines...
