BACKGROUND: Midline nasal dermoid cysts are rare congenital anomalies that extend intracranially in approximately 10 percent of cases. Cysts with intracranial extension require a craniotomy to avoid long-term complications, including meningitis, abscesses, and cavernous sinus thrombosis. Current guidelines recommend preoperative imaging with either magnetic resonance imaging or computed tomography to determine appropriate management. METHODS: Patients who underwent excision of a midline nasal dermoid cyst between January 1995 and September 2016 were identified using Current Procedural Terminology codes...

We report on the synthesis of alpha manganese dioxide (α-MnO₂) nanorods using natural extracts from Vitis vinifera grape stems and Malus domestica 'Cortland' apple peels. We used a two-step method to produce highly crystalline α-MnO₂ nanorods: (1) reduction of KMnO₄ in the presence of natural extracts to initiate the nucleation process; and (2) a thermal treatment to enable further solid-state growth of the nuclei. Transmission electron microscopy (TEM) and field emission scanning electron microscopy (FESEM) images provided direct evidence of the morphology of the nanorods and these images were used to propose nucleation and growth mechanisms...

Purple urine bag syndrome (PUBS) is a unique phenomenon characterized by purple discoloration of the urinary catheter bag and tubing following urinary catheterization lasting for hours to days. The purple discoloration is a mixture of indirubin dissolved in plastic with indigo on its surface. PUBS is most commonly associated with urinary tract infection (UTI) caused by bacteria with indoxyl phosphatase/sulfatase activity. It occurs predominantly in chronically catheterized, constipated elderly female patients...

Intra-amniotic dye instillation is a useful tool for evaluation of equivocal cases of preterm prelabor rupture of membranes and for genetic amniocentesis in multifetal gestation. Indigo carmine, the most used and studied dye, is no longer available. We sought to provide a resource of potential dyes for clinical use that summarizes dosing along with maternal, fetal, and neonatal outcomes. We reviewed the literature evaluating the use of alternative agents. Sodium fluorescein has proven clinical usefulness but has side effects when used intravenously...

Due to consumers' increasing health awareness, food industry aims at replacing synthetic dyes by natural counterparts. The substitution of blue synthetic dyes is particularly challenging since current natural alternatives such as phycocyanin (Spirulina) suffer from poor stability. Jagua blue (produced from Genipa americana L. fruit) might represent a potential novel blue pigment source. However, only little is known about its color properties, and application in food systems. Therefore, the blue color and the stability of Jagua blue were assessed for the first time and compared to commonly used colorants, namely, Spirulina, brilliant blue FCF (Blue no...

Unrestricted and reckless use of antibiotics has resulted in their accumulation in environment. This, in turn, has led to the emergence of multiple drug-resistant microbes. The present study focuses on degradation of ciprofloxacin (CIP) by an edible white rot fungus Pleurotus ostreatus. Effect of CIP was determined on radial growth and biomass of P. ostreatus. Titrimetric and spectrophotometric assays were carried out to assess the degrading potential of P. ostreatus towards CIP. It was found that CIP has a stimulatory effect on growth and enzyme activity of P...

Background and aims Colonoscopy is currently the reference method to detect colorectal neoplasia, yet some adenomas remain undetected. The water infusion technique and dying with indigo carmine has shown interesting results for reducing this miss rate. The aim of this study was to compare the adenoma detection rate (adenoma and adenocarcinoma; ADR) and the mean number of adenomas per patient (MAP) for blue-water infusion colonoscopy (BWIC) versus standard colonoscopy. Methods We performed a multicenter, randomized controlled trial in eight units, including patients with a validated indication for colonoscopy (symptoms, familial or personal history, fecal occult blood test positive)...

The reaction between indigo, H2Ind, and {Ru(bpy)2(EtOH)2}(2+) in EtOH/NaOH produced the compounds [Ru(bpy)2(HInd)]ClO4 [1]ClO4, rac-{[Ru(bpy)2]2(μ-Ind)}(ClO4)2 [2](ClO4)2, and meso-{[Ru(bpy)2]2(μ-Ind)}(ClO4)3 [2](ClO4)3, which were structurally characterised, the latter as the first stable, isolable radical complex of indigo. The redox pair 2(2+)/2(3+) showed little structural difference, as confirmed using DFT calculations. The redox series 1(n) and 2(n) were investigated using voltammetry and spectroelectrochemistry (EPR, UV-vis-NIR)...

Birds have a light-dependent magnetic compass that provides information about the spatial alignment of the geomagnetic field. It is proposed to be located in the avian retina and mediated by a light-induced, radical-pair mechanism involving cryptochromes as sensory receptor molecules. To investigate how the behavioural responses of birds under different light spectra match with cryptochromes as the primary magnetoreceptor, we examined the spectral properties of the magnetic compass in zebra finches. We trained birds to relocate a food reward in a spatial orientation task using magnetic compass cues...

This work investigates the application of a microfiltration (MF) - membrane bioreactor (MBR) hybrid process for textile dyeing process wastewater reclamation. The indigo blue dye was efficiently retained by the MF membrane (100%), which allows its recovery from the concentrate stream. The MF promotes 100% of colour removal, and reduce the COD and conductivity by about 65% and 25%, respectively and improves the wastewater biodegradability. MF flux decline was mostly attributed to concentration polarization and the chemical cleaning was efficient enough to recover initial hydraulic resistance...
