Magnetic particles entrapped in different matrices that display high thermal stability, low toxicity, interactive functions at the surface, and high saturation magnetization are of great interest. The objective of this work was to synthesize a novel hemoglobin/iron oxide composite (Hb/Fe3 O4 ) for the removal of different dyes (indigo carmine, naphthol blue black, tartrazine, erythrosine, eriochrome black T and bromophenol blue) from aqueous solutions. The Hb/Fe3 O4 composite was characterized using scanning electron microscopy (SEM), laser diffraction particle size analysis, FT-IR spectroscopy, isoelectric point determination and thermogravimetric analysis (TGA)...

Treatment of renal vein thromboses has previously been limited to conventional anticoagulation. We describe a case of successful treatment of acute native renal vein thrombosis in a 61-year-old fit and well female using mechanical thromboaspiration without the use of thrombolysis. The report demonstrates the CT appearances of an acute renal vein thrombosis, the venographic images pre- and post-thromboaspiration and the MR imaging of the kidney 3 months later, showing complete resolution of the thrombus and normal appearances of the kidney...

Pityriasis rosea (PR), a skin rash, causes substantial discomfort in patients. There is a lack of effective therapies for PR. A combination of ultraviolet irradiation and indigo naturalis treatment has been shown to be a safe and effective regime for control of PR; however, the data have been largely inconsistent. Tis meta-analysis further evaluated the efficacy and safety of this combination in patients with PR. The PubMed, Embase, Cochrane Library, CNKI, VIP, and Wan Fang databases were searched for relevant RCTs of this combination therapy in patients with PR...

Using split plot design, a pot experiment with sand culture was conducted to investigate the effects ofnitrogen and sulfur combined application on nutritional components and active component of Isatis indigotica at seedling stage under different N (5,15,25 mmol·L⁻¹)and S(0.00,1.25,2.50,5.00,7.50 mmol·L⁻¹) levels. The results showed thatthe two elements had obvious effects and the leaf and root dry weights of I. indigotica seedlings increased greatly at N₂ level. Under the same nitrogen concentration, the leaf and root dry weights increased firstly and decreased with the rising of sulfur concentrations in which S₂ was conducive to the growth and biomass accumulation...

A multicopper oxidase (IOX) produced by Iodidimonas sp. Q-1 has high catalytic efficiency for iodide (I- ) oxidation to form molecular iodine (I2 ). In this study, the potential capacity of IOX for decolorization of recalcitrant dyes was determined. Although IOX did not decolorize any dyes in the absence of redox mediator, significant decolorization of Orange G, Indigo Carmine, Amido Black, and Remazol Brilliant Blue R (RBBR) was observed in the presence of iodide. Addition of 0.1 mM iodide was sufficient to decolorize a total of 3 mM Indigo Carmine, suggesting that iodide functions as a mediator...

A 60-year-old woman underwent colonoscopy, which revealed a red, 5-mm protruded lesion in the sigmoid colon, surrounded by white spots in white-light imaging. Indigo carmine spray indicated endoscopic morphological type Is + IIc. The vessel pattern was diagnosed as JNET-type 2B in magnifying narrow-band imaging, and magnified crystal violet-stained images revealed a VI low-grade pit pattern. We endoscopically diagnosed this lesion as an intramucosal or slightly invasive submucosal carcinoma with low confidence, and performed endoscopic mucosal resection to obtain a total biopsy...

The aim of this study was to overproduce, identify and apply novel laccase-like multicopper oxidases (LMCOs) from Myrothecium roridum in a dye removal process. LMCOs' production was enhanced by modifying the medium and adding copper ions. After purification, two proteins, LMCO1 and LMCO2, with molecular masses of 46.7 and 66.3 kDa were discovered. Peptide analysis by mass spectrometry revealed that they belong to the cupredoxin superfamily. Characteristic peptide sequences were obtained for MCOs and bilirubin oxidases...

Indigoid photoswitches comprise a class of chromophores that are derived from the parent and well-known indigo dye. Different from most photoswitches their core structures absorb in the visible region of the spectrum in both isomeric states even without substitutions, which makes them especially interesting for applications not tolerant of high-energy UV light. Also different from most current photoswitching systems, they provide highly rigid structures that undergo large yet precisely controllable geometry changes upon photoisomerization...

Pickering emulsions stabilized by a mixture of colored organic pigment particles of different hydrophobicity have been investigated at equal oil/water ratio and a fixed overall particle concentration by several complementary methods. Transitional phase inversion of emulsions from water-in-oil to oil-in-water can be effected by increasing the fraction of hydrophilic pigment orange in mixtures with either hydrophobic pigment yellow, red, indigo, or blue. In two mixtures, we find that a distinct change in the color of emulsions occurs at phase inversion...

Long-standing ulcerative colitis (UC) and extensive Crohn's colitis confer increased risk for development of colorectal cancer. Screening and surveillance colonoscopy programs aim to identify, resect, or detect dysplasia or colorectal cancer. Dysplastic lesions can be removed by endoscopic resection and patients with unresectable lesions can be referred for colectomy at an earlier stage, with the goal of reducing overall morbidity and mortality from colorectal cancer. Surveillance colonoscopy for patients with inflammatory bowel disease (IBD) is endorsed by multiple specialty societies...

Detection of body fluid-specific mRNAs, such as those specific for blood, using real-time polymerase chain reaction (PCR) has become a useful tool in forensic science. Blood stains often contain PCR inhibitors that may be co-extracted with RNA and adversely affect PCR. The effects of inhibitors on the detection of mRNA markers for blood identification, namely, hemoglobin beta (HBB) and actin beta, were examined herein. Inhibitors were added to a real-time PCR mix, reverse transcription mix, and blood samples before RNA extraction, and the following parameters: Ct, delta Ct (dCt), and melting temperature (Tm) values, were monitored...

Nanostructured semiconductors are one of the most potent candidates for matrix-free laser desorption/ionization mass spectrometric (LDI-MS) analysis of low molecular weight molecules. Herein, the enhanced photoinduced electron transfer and LDI on the tip of vertical silicon nanowires (SiNWs) array were investigated. Theoretical simulation and LDI detection of indigo and isatin molecules in negative mode revealed that electric field can be enhanced on the tip end of SiNWs, thereby promoting the energy and electron transfer to analytes adsorbed on the tip of SiNWs...

The polycomb repressive complex 2 (PRC2) consists of core subunits SUZ12, EED, RBBP4/7, and EZH1/2 and is responsible for mono-, di-, and tri-methylation of lysine 27 on histone H3. Whereas two distinct forms exist, PRC2.1 (containing one polycomb-like protein) and PRC2.2 (containing AEBP2 and JARID2), little is known about their differential functions. Here, we report the discovery of a family of vertebrate-specific PRC2.1 proteins, "PRC2 associated LCOR isoform 1" (PALI1) and PALI2, encoded by the LCOR and LCORL gene loci, respectively...

Blue diaper syndrome (BDS) (Online Mendelian Inheritance in Man number 211000) is an extremely rare disorder that was first described in 1964. The characteristic finding is a bluish discoloration of urine spots in the diapers of affected infants. Additional clinical features of the first described patients included diarrhea, inadequate weight gain, hypercalcemia, and nephrocalcinosis. An intestinal defect of tryptophan absorption was postulated as the underlying pathology. However, functional evidence for this theory is lacking...

Orally administered Qing-dai, called indigo naturalis in Latin, is reportedly useful for the treatment of ulcerative colitis. We herein describe two patients with ulcerative colitis who developed colitis with wall thickening and edematous changes during oral administration of the powdered form of Qing-dai. In Case 1, a 35-year-old man developed colitis similar to ischemic colitis with bloody stool that recurred each time he ingested Qing-dai. He had no signs of recurrence upon withdrawal of Qing-dai. In Case 2, a 43-year-old woman underwent ileocecal resection for treatment of an intussusception 2 months after beginning oral administration of Qing-dai...

INTRODUCTION AND AIMS: Gastric cancer is one of the main causes of cancer worldwide, but there is currently no global screening strategy for the disease. Endoscopy is the screening method of choice in some Asian countries, but no standardized technique has been recognized. Systematic alphanumeric-coded endoscopy can increase gastric lesion detection. The aim of the present article was to compare the usefulness of systematic alphanumeric-coded endoscopy with conventional endoscopy for the detection of premalignant lesions and early gastric cancer in subjects at average risk for gastric cancer...
