BACKGROUND Single-balloon endoscopy (SBE) has been introduced as a simplified endoscopy technique after the promotion of double-balloon endoscopy (DBE). The difference in clinical performance between DBE and SBE is still not very clear. In this study, we aimed to compare the efficacy and safety between these 2 endoscopic procedures. MATERIAL AND METHODS A total of 173 patients with suspected small bowel disease were enrolled into this study from January 2007 to December 2011. All cases were divided into DBE or SBE groups according to the endoscopic procedures they underwent...

Background. Meckel's diverticulum (MD) is the most common congenital anomaly of the gastrointestinal tract. The purpose of this study was to evaluate the diagnostic value and safety of double-balloon enteroscopy (DBE) for bleeding MD in children. Methods. We included consecutive children who were highly suspected of MD between 2012 and 2013. All patients underwent Meckel's scan. DBE was performed for patient with negative Meckel's scan. An exploratory laparoscopy was performed in children with positive Meckel's scan or DBE...

The comprehensive description of complex mixtures such as bio-oils is required to understand and improve the different processes involved during biological, environmental or industrial operation. In this context, we have to consider how different ionization sources can improve a non-targeted approach. Thus, the Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) has been coupled to electrospray ionization (ESI), laser desorption ionization (LDI) and atmospheric pressure photoionization (APPI) to characterize an oak pyrolysis bio-oil...

Background/Aims: Studies concerning the efficacy and safety of single-balloon enteroscopy (SBE) compared with that of double-balloon enteroscopy (DBE) often appear to be conflicting. However, previous studies were performed by endoscopists who were less experienced in SBE compared with DBE. Methods: We performed a retrospective analysis of SBE and DBE data performed by a single enteroscopist, with expertise in SBE, using a prospective balloon-assisted enteroscopy registry from 2013 to 2015...

1,2-Dibromoethane (DBE, ethylene dibromide) is a potent carcinogen due at least in part to its DNA cross-linking effects. DBE cross-links glutathione (GSH) to DNA, notably to sites on 2'-deoxyadenosine and 2'-deoxyguanosine ( Cmarik , J. L. , et al. ( 1991 ) J. Biol. Chem. 267 , 6672 - 6679 ). Adduction at the N6 position of 2'-deoxyadenosine (dA) had not been detected, but this is a site for the linkage of O(6)-alkylguanine DNA alkyltransferase ( Chowdhury , G. , et al. ( 2013 ) Angew. Chem. Int. Ed. 52 , 12879 - 12882 )...

Short double-balloon enteroscopy (DBE) has facilitated endoscopic retrograde cholangiopancreatography (ERCP) in patients with surgically altered anatomies (1-3) . However, the advantage of the short DBE is not limited to improving success of scope insertion into the target site. We report a case wherein short DBE was useful for biliary cannulation and treatment via the papilla of Vater, which had failed using conventional pediatric colonoscopy (PC) (4,5) This article is protected by copyright.

Contaminated soil organic matter from the Rocky Flats Environmental Technology Site (RFETS) has been previously shown to accumulate plutonium (Pu) in a colloidal subfraction and is hypothesized to contain cutin-like chemical structures cross-linked with hydroxamate functionality. The present study further characterizes this high Pu affinity subfraction using electrospray ionization Fourier transform ion cyclotron resonance mass spectrometry (ESI-FTICRMS) and discovers additional substructural components. The Pu-enriched fraction was extracted and purified through a series of ultrafiltration and isoelectric focusing (IEF) electrophoresis steps...

Light-sheet microscopy is an effective technique in neuroscience, developmental biology, and cancer research for visualizing and analyzing cellular networks and whole organs in three dimensions. Because this technique requires specimens to be translucent they commonly have to be cleared before microscopy inspection. Here, we provide 3DISCO based protocols for preparing cleared samples of immuno-stained neural networks, lectin-labeled vascular networks, and Methoxy-X04 labeled beta-amyloid plaques in mice. 3DISCO utilizes the lipophilic solvents tetrahydrofuran (THF) and dibenzylether (DBE) for dehydration and successive clearing...

BACKGROUND: Sizable small-bowel (SB) polyps in Peutz-Jeghers syndrome (PJS) pose a high risk for intussusception, often necessitating laparotomy and intraoperative-enteroscopy (IOE). This series examines the effectiveness of double-balloon enteroscopy (DBE) facilitated polypectomy for pediatric patients with PJS. METHODS: Prospective analysis of collected data (6 years) on all patients with PJS referred for DBE-facilitated SB polypectomy at a pediatric tertiary-referral center...

Meckel diverticulum (MD) is a common small intestinal malformation. The difficulty of MD with hemorrhage treatment lies in preoperative diagnosis. Wireless capsule endoscopy (WCE) and double-balloon enteroscopy (DBE) have been widely used to diagnose and treat diseases of the small intestine, but only rarely have they been used in combination to diagnose and treat bleeding MD. We successfully diagnosed and treated a patient with MD with hemorrhage with a combination of WCE, DBE, and laparoscopy. A 17-year-old man presented to the emergency room with hematochezia and was admitted for testing...

Control over polymer sequence and architecture is crucial to both understanding structure-property relationships and designing functional materials. In pursuit of these goals, we developed a new synthetic approach that enables facile manipulation of the density and distribution of grafts in polymers via living ring-opening metathesis polymerization (ROMP). Discrete endo,exo-norbornenyl dialkylesters (dimethyl DME, diethyl DEE, di-n-butyl DBE) were strategically designed to copolymerize with a norbornene-functionalized polystyrene (PS), polylactide (PLA), or polydimethylsiloxane (PDMS) macromonomer mediated by the third-generation metathesis catalyst (G3)...

Background and study aims Diagnosis of Meckel's diverticulum (MD) before surgery may be challenging; double-balloon endoscopy (DBE) facilitates identification of MD in the setting of a gastrointestinal bleeding; however, MD can be found incidentally without this condition. The purpose of this research was to determine specific characteristic of hemorrhagic MD and incidental MD at DBE. Patients and methods Ectopic gastric mucosa enclosed in the MD and/or ulceration were defined as "major findings"; ring-like scar surrounding the MD was defined as "minor finding"...

BACKGROUND: Maintenance of mucosal healing is a primary goal when treating Crohn's disease (CD). Endoscopy is the most precise method for the assessment of mucosal healing, but is considered overly invasive for patients with CD. In contrast, CT enterography (CTE) is less invasive, but little is known about the correlation between mucosal status and CTE parameters. METHODS: We recruited CD patients who underwent CTE and double balloon endoscopy (DBE) on the same day at our hospital between 2012 and 2014...

Simplification of highly complex mixtures such as crude oil by using chromatographic methods makes it possible to get more detailed information about the composition of the analyte. Separation by argentation chromatography can be achieved based on the interaction of different strength between the silver ions (Ag(+)) immobilized through a spacer on the silica gel surface and the π-bonds of the analytes. Heavy crude oils contain compounds with a high number of heteroatoms (N, O, S) and a high degree of unsaturation thus making them the perfect analyte for argentation chromatography...

Obese and diabetic individuals are at increased risk for impairments in diastolic relaxation and heart failure with preserved ejection fraction. The impairments in diastolic relaxation are especially pronounced in obese and diabetic women and predict future cardiovascular disease (CVD) events in this population. Recent clinical data suggest sodium glucose transporter-2 (SGLT2) inhibition reduces CVD events in diabetic individuals, but the mechanisms of this CVD protection are unknown. To determine whether targeting SGLT2 improves diastolic relaxation, we utilized empagliflozin (EMPA) in female db/db mice...
