[Ab] Resumo:OBJECTIVE: To retrospectively evaluate the feasibility of CT fluoroscopy-guided percutaneous marking using a 25-gauge needle and indigo carmine before video-assisted thoracoscopic surgery (VATS) for small lung lesions. METHODS: 21 patients, 14 males and 7 females, with a median age of 69 years (range, 40-79), underwent CT fluoroscopy-guided percutaneous VATS marking using a 25-gauge, 70-mm needle and 1.5-ml indigo carmine. The mean diameter of the lung lesions was 14 mm (range, 6-27). We evaluated the technical success rate, surgical success rate and complications related to this procedure by reviewing medical records and images. Technical success was defined as completion of this procedure. Surgical success was defined as resection of the target lesion with negative margins on pathological examination after VATS. Complications that required advanced levels of care were classified as major complications, and the remaining complications were considered minor. RESULTS: The technical success rate was 100%. In all cases, VATS was successfully performed as planned, and the target lesion was resected with negative margins on pathological examination after VATS. Thus, the surgical success rate was 100%. Mild pneumothorax was found in two cases, but further treatment was not required. The minor complication rate was 9.5% (2/21), and major complication rate was 0%. Only two patients (9.5%) complained of slight pain upon puncture, but local anaesthesia was not required. CONCLUSION: Percutaneous CT fluoroscopy-guided VATS marking using a 25-gauge needle without local anaesthesia appears feasible and safe. Advances in knowledge: This technique expands a possibility of the CT-guided marking.

[Ti] Título:In vitro characterization of CYP102G4 from Streptomyces cattleya: A self-sufficient P450 naturally producing indigo.

[Ab] Resumo: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. It showed hydroxylation activity toward fatty acids generating ω-1, ω-2, and ω-3-hydroxyfatty acids, which is similar to the general substrate specificity of CYP102 family. Unexpectedly, however, expression of CYP102G4 showed indigo production in LB medium batch flask culture, and high catalytic activity (k /K ) for indole was measured as 6.14±0.10min mM . Besides indole, CYP102G4 was able to hydroxylate aromatic compounds such as flavone, benzophenone, and chloroindoles. Homology model has shown such ability to accept aromatic compounds is due to its bigger active site cavity. Unlike other CYP102s, CYP102G4 did not have biased cofactor dependency, which was possibly determined by difference in NAD(P)H binding residues (Ala984, Val990, and Tyr1064) compared to CYP102A1 (Arg966, Lys972 and Trp1046). Overall, a self-sufficient CYP within CYP102G subfamily was characterized using purified enzymes, which appears to possess unique properties such as an only prokaryotic CYP naturally producing indigo.

[Ab] Resumo:Obligately alkaliphilic, indigo-reducing strains, designated Bps-1 , 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-1 has a distinctive position among the alkaliphilic species of the genus Bacillus, with its closest neighbours being Bacillus pseudofirmus DSM 8715 , Bacillus lindianensis DSM 26864 and Bacillus alcalophilus DSM 485 (96.1, 95.8 and 95.5 % 16S rRNA gene sequence similarities, respectively). The 16S rRNA sequence of strain Bps-1 was identical to those of strains Bps-2 and Bps-3. Cells of the novel isolate were Gram-stain-positive and were facultatively anaerobic straight rods that were motile by means of a pair of flagella (subpolar and centre sides). Spherical endospores were formed in the terminal position. Strain Bps-1 grew between 18 and 40 °C with optimum growth at 33 °C. The isolate grew in the pH range 8‒11, with optimum growth at pH 9‒10. The isoprenoid quinone detected was menaquinone-7 (MK-7), and the DNA G+C content was 40.3 %. The whole-cell fatty acid profile (>10 %) mainly consisted of anteiso-C15 : 0, iso-C15 : 0 and C16 : 0. On the basis of the phenotypic, chemotaxonomic and phylogenetic data, the isolates represent a novel species of a novel genus, for which the name Paralkalibacillus indicireducens gen. nov., sp. nov. is proposed. The type strain of this species is Bps-1 (JCM 31808 =NCIMB 15080 ), with strains Bps-2 and Bps-3 representing additional strains of the species.

[Ab] Resumo: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. The calcined materials immobilized much larger amounts of indigo carmine dye than the uncalcined layered double hydroxides (LDHs) specimens. The maximum adsorption capacities obey the order: CZnAl-4 (520.8 mg/g) > CZnAl-3 (358.4 mg/g) > ZnAl-3 (67.25 mg/g) > ZnAl-4 (21.65 mg/g). The adsorption isotherms are best described by Langmuir model. The sorption process is spontaneous in nature and its kinetics data are best described by a pseudo-second-order model. Adsorption tests on re-used calcined clays demonstrate its reusability after three thermal cycles.

[Ab] Resumo:The Indigo carmine (IC) dye has been widely used in textile industries, even though it has been considered toxic for rats, pigs and humans. Owing to its toxicity, wastes containing this compound should be treated to minimize or eliminate their toxic effects on the biota. As an alternative to wastewater treatment, advanced oxidative processes (AOPs) have been highlighted due to their high capacity to destruct organic molecules. In this context, this study aimed to evaluate Indigo Carmine toxicity to soil organisms using the earthworm Eisenia andrei as a model-organism and also verify the efficiency of AOP in reducing its toxicity to these organisms. To this end, lethal (mortality) and sub-lethal (loss or gain of biomass, reproduction, behavior, morphological changes and immune system cells) effects caused by this substance and its degradation products in these annelids were evaluated. Morphological changes were observed even in organisms exposed to low concentrations, while mortality was the major effect observed in individuals exposed to high levels of indigo carmine dye. The organisms exposed to the IC during the contact test showed mortality after 72h of exposure (LC = 75.79mgcm ), while those exposed to photoproducts showed mortality after 48h (LC = 243min). In the chronic study, the organisms displayed a mortality rate of 14%, while those exposed to the photoproduct reached up to 32.7%. A negative influence of the dye on the reproduction rate was observed, while by-products affected juvenile survival. A loss of viability and alterations in the cellular proportion was verified during the chronic test. However, the compounds did not alter the behavior of the annelids in the leak test (RL ranged from 20% to 30%). Although photocatalysis has been presented as an alternative technology for the treatment of waste containing the indigo carmine dye, this process produced byproducts even more toxic than the original compounds to E. andrei.

[Ab] Resumo:BACKGROUND: The goal of treatment for spinal arteriovenous lesions is to completely obliterate the shunt. In our institution, intraoperative digital subtraction angiography and intraarterial injection of contrast agent have been used to accurately identify the site of arteriovenous shunts. We describe the intraoperative digital subtraction angiography and intraarterial dye injection procedures and how they may improve surgical outcomes. METHODS: We retrospectively investigated 22 patients with intradural arteriovenous lesions (n = 19) or spinal dural arteriovenous fistulas (n = 3). A microcatheter was used during the procedures to avoid catheter migration. RESULTS: There were 29 procedures performed. To support the surgical procedures, indigo carmine was used 17 times and indocyanine green was used 12 times. There were no complications associated with these procedures. The indocyanine green procedure required a lower concentration of dye in the artery than in the vein to clarify the shunt point and visualized complex lesions more clearly. These methods allowed surgeons to orientate the complex vessel structure. CONCLUSIONS: Intraoperative digital subtraction angiography and intraarterial dye injection are useful tools for management of spinal arteriovenous lesions.

[Ab] Resumo:BACKGROUND: Indigo naturalis (IND) is an herbal medicine that has been used as an anti-inflammatory agent to treat diseases including dermatitis and inflammatory bowel disease in China. However, the mechanism by which IND exerts its immunomodulatory effect is not well understood. METHODS: A murine model of dermatitis and inflammatory bowel disease, both induced by oxazolone (OXA), was treated with IND. The severity of dermatitis was evaluated based on ear thickness measurements and histological scoring. The severity of colitis was evaluated by measuring body weight, histological scoring, and endoscopic scoring. The expression of inflammatory cytokines in ear and colon tissue was evaluated using real-time PCR. 16S rRNA DNA sequencing of feces from OXA-induced colitis mice was performed before and after IND treatment. The effects of IND on OXA-induced colitis were also evaluated after depleting the gut flora with antibiotics to test whether alteration of the gut flora by IND influenced the course of intestinal inflammation in this model. RESULTS: IND treatment ameliorated OXA dermatitis with a reduction in IL-4 and eosinophil recruitment. However, OXA colitis was significantly aggravated in spite of a reduction in intestinal IL-13, a pivotal cytokine in the induction of the colitis. It was found that IND dramatically altered the gut flora and IND no longer exacerbated colitis when colitis was induced after gut flora depletion. CONCLUSIONS: Our data suggest that IND could modify the inflammatory immune response in multiple ways, either directly (i.e., modification of the allergic immune cell activity) or indirectly (i.e., alteration of commensal compositions).

[Ab] Resumo:Previous works conducted in our laboratory, reveled that Bacillus aryabhattai DC100 produce ligninolytic enzymes such as laccases and/or peroxidases, opening new applications in different bioprocesses, including the treatment of disposal residues such as dyestuffs from textile processing industries. This work described the degradation of three commercial model dyes Coomassie Brilliant Blue G-250 (CBB), Indigo Carmine (IC) and Remazol Brilliant Blue R (RBBR) under different culture media and operational conditions. The process was optimized using a Central Composite Rotatable Design, and the desirability predicted complete decolorization of 150 mg/L CBB at 37 °C, 304.09 rpm and salt concentration of 19.204 g/L. The model was validated with concentrations up to 180 mg/L CBB and IC, not being able to remove high amount of RBBR. The procedure here developed also allowed Chemical Oxygen Demands (COD) reductions in CBB of about 42%, meanwhile tests on real effluents from a local textile industry involved COD reductions of 50% in a liquid wastewater and 14% in semi-liquid sludge. Thus, allow the authorized discharge of wastewater into the corresponding treatment plant. Decolorization efficiencies and COD reductions open on the potential application of B. aryabhattai DC100 on the bioremediation of real effluents from textile industries.

[Ab] Resumo:Although the indigo reduction process is performed via natural fermentation and maintained under open-air condition, the indigo-reducing reactions continue for 6 months (on average) or longer. Identifying the mechanism underlying the maintenance of this process could lead to the development of a novel, long-lasting, unsterilized bioprocesses. To determine the mechanisms underlying the maintenance of the indigo fermentation system microbiota for more than 6 months in a reduced state in an anaerobic alkaline environment, we examined changes in the microbiota in one early-phase batch and two aged batches of indigo fermentation fluid. The microbiota in the aged fermentation fluid consisted mainly of the genera Alkalibacterium, Amphibacillus, Anaerobacillus and Polygonibacillus and the family Proteinivoraceae. The genera Alkalibacterium, Amphibacillus and Polygonibacillus are known to include indigo-reducing bacteria. Although the transition speed was slower in the aged fermentation fluid than in the early-stage fluid, the microbiota in the aged fermentation fluid maintained for more than 6 months was drastically changed within a period of 3 months. The results of this study indicate that the bacterial consortia consisted of various indigo-reducing species that replace the previous group of indigo-reducing bacteria. The notable transitional changes may be concomitant with changes in the environmental conditions, such as the nutritional conditions, observed over 3 months. This flexibility may lead to important changes in the microbiota that allow for the maintenance of a fermentation-reducing state over a long period.

[Ab] Resumo:A new approach for removal of indigo carmine blue (IC) dye which is extensively used in jeans manufacture was successfully performed on novel mesoporous [LDH] nanoparticles prepared by sol-gel route using CTAB as shape and pore directing agent. The physicochemical features were monitored by X-ray diffraction (XRD), Fourier transformer infra-red (FTIR), N adsorption-desorption isotherm, Field emission electron microscope (FESEM) and high resolution transmission electron microscope (HRTEM). The influence of reaction parameters affecting dye adsorption including contact time, initial dye concentration, pH and temperature were investigated. Textural analysis and HRTEM images indicate the existence of mesoporous spherical nanoparticles of size = 26 nm connected to each other's and embedded large numbers of mesopores of average pore radius = 43.5 Å. A successful adsorption of IC on LDH nanoparticles of surface area = 85.6 m /g at various pH with maximum adsorption capacity = 62.8 mg/g at pH = 9.5. Langmuir model is more favorable to describe the adsorption of IC rather than Freundlich model which reflecting the preferential formation of monolayer on the surface of LDH. Both film diffusion and the intraparticle diffusion affect the dye adsorption. The values of enthalpy change (ΔH) for and (ΔS) are + 28.18 and + 0.118 kJ/mol, respectively indicating that the removal process is endothermic. The results indicated that LDH nanoparticles conserved a good activity even after five consecutive cycles of reuse. Our results suggest that mesoporous LDH nanoparticles are considered a potential novel adsorbent for remediation of wastewater containing IC.
