Single clonal tracing and analysis at the whole-heart level can determine cardiac progenitor cell behavior and differentiation during cardiac development, and allow for the study of the cellular and molecular basis of normal and abnormal cardiac morphogenesis. Recent emerging technologies of retrospective single clonal analyses make the study of cardiac morphogenesis at single cell resolution feasible. However, tissue opacity and light scattering of the heart as imaging depth is increased hinder whole-heart imaging at single cell resolution...

Scotch Whisky is an important product, both culturally and economically. Chemically, Scotch Whisky is a complex mixture, which comprises thousands of compounds, the nature of which are largely unknown. Here, we present a thorough overview of the chemistry of Scotch Whisky as observed by Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS). Eighty-five whiskies, representing the majority of Scotch Whisky produced and sold, were analyzed by untargeted high-resolution mass spectrometry. Thousands of chemical formulae were assigned for each sample based on parts-per-billion mass accuracy of FT-ICR MS spectra...

A 72-year-old woman with ulcerative colitis was referred to our hospital because of refractory diarrhea. Although she had been treated with prednisolone 12.5 mg/day and mesalazine suppositories 1 g/day, her watery diarrhea persisted. Colonoscopy was undergone 30 days after she started administration of mesalazine suppositories, and showed granularity of the mucosa with little erythematous appearance in the entire colon with endoscopic Mayo score 1. Double-contrast small-bowel radiography showed a rough mucosal surface in the terminal ileum...

The over-the-scope clip (OTSC) system is a new technology that enables closure of fistulae which cannot be closed with a conventional clip. A 57-year-old woman had long-term hypoalbuminemia, edema and general malaise. Peroral double-balloon endoscopy (DBE) showed a jejuno-sigmoid fistula and blind loop syndrome of the jejunum and ileum, because ingested food bypassed the ileum through the fistula. She was advised to undergo surgical closure of the fistula, but she refused the procedure. For 7 years following DBE, repeat courses of antibiotics were required to treat bacterial overgrowth due to blind loop syndrome...

BACKGROUND: Bleeding lesions of the small bowel are often difficult to identify due to the obscure symptomatology. Localizing these lesions requires specific techniques. The Double-balloon enteroscopy (DBE) could be used to precisely localize and mark lesions, so that a minimally invasive surgical treatment could be performed. METHODS: Twenty robot-assisted small bowel procedures are presented using a combination of DBE for localization and robotic resection. RESULTS: There were 10 jejunal resections and 10 ileal resections...

Double balloon enteroscopy (DBE) was introduced 15 years ago. The complications of diagnostic DBE are rare, acute pancreatitis is most redoubtable one (incidence about 0.3%). Hyperamylasemia after DBE seems to be a rather common condition respectively. The most probable cause seems to be a mechanical straining of the pancreas. We tried to identify patients in a higher risk of acute pancreatitis after DBE. We investigated several laboratory markers before and after DBE (serum cathepsin B, lactoferrin, E-selectin, SPINK 1, procalcitonin, S100 proteins, alfa-1-antitrypsin, hs-CRP, malondialdehyde, serum and urine amylase and serum lipase)...

Thiols widely occur in sediments and fossil fuels. However, the molecular composition of these compounds is unclear due to the lack of appropriate analytical methods. In this work, a characterization method for thiols in fossil fuels was developed on the basis of Michael addition reaction derivatization followed by electrospray ionization Fourier transform ion cyclotron resonance mass spectrometry (ESI FT-ICR MS). Model thiol compound studies showed that thiols were selectively reacted with phenylvinylsulfone and transformed to sulfones with greater than 98% conversions...

The patient was a 72 year old man who had been given non-steroidal anti-inflammatory drug (NSAID) for two years. He repeatedly developed small intestinal ileus; therefore, he underwent several imaging examinations, but the cause was not identified. He subsequently underwent a double-balloon endoscopy (DBE). The membranous stenoses were detected in the jejunum, and the biopsy specimens were taken during the DBE. The membranous stenoses in the gastrointestinal tract were characteristic of NSAID-induced enteropathy, and he was endoscopically and histopathologically diagnosed with NSAID-induced small intestinal disorder...

UNLABELLED: Double-balloon endoscopy (DBE) is useful for the diagnosis and treatment of small bowel diseases. Although fluoroscopy is used to confirm the position of endoscope at DBE, the endoscopist does not have the knowledge with regard to the radiation exposure dose. In this study, we evaluated the absorbed dose during DBE in patients with suspected or established small bowel diseases. This was a retrospective study in which the estimated fluoroscopic radiation absorbed doses loaded on the small bowel and skin were determined according to the data of the referential X-ray experiment with a human body phantom...

BACKGROUND: Roux-en-Y reconstructive surgery excludes the biliopancreatic system from conventional endoscopic access. Balloon-assisted enteroscopy allows therapeutic endoscopic retrograde cholangiopancreatography (ERCP) in these patients, avoiding rescue surgery. The objective of the current study is to compare success and complication rate of double-balloon (DBE) and single-balloon enteroscope (SBE) to perform ERCP in Roux-en-Y patients. METHODS: Seventy three Roux-en-Y patients with suspected biliary tract pathology underwent balloon-assisted enteroscopy in a tertiary-care center...

Dissolved organic matter samples extracted from ground water at the USGS Bemidji oil spill site in Minnesota were investigated by ultrahigh resolution mass spectrometry. Principle component analysis (PCA) of the elemental composition assignments of the samples showed that the score plots for the contaminated sites were well separated from those for the uncontaminated sites. Additionally, spectra obtained from the same sampling site 7 and 19 years after the spill were grouped together in the score plot, strongly suggesting a steady state of contamination within the 12year interval...

A 21-year-old female underwent a Kasai hepatoportoenterostomy with Roux-en-Y reconstruction for typeIII biliary atresia at age 63 days. At the age of 19 years, she developed cholangitis and CT scan revealed hepatolithiasis. She presented for treatment of the intrahepatic stone and the hepatportoenterostomy was directly visualized with double-balloon endoscopy (DBE). Endoscopic findings showed multiple intrahepatic bile ducts open to the jejunum through multiple orifices. Cholangiography showed narrowing of intrahepatic bile duct branches with a "fire-like" appearance...

After oil sands process affected water (OSPW) was treated in a continuous flow biofilm reactor, about 40% of the organic compounds in the acid extractable fraction (AEF) including naphthenic acids (NAs) were degraded resulting in a reduction of 73% in the Microtox acute toxicity and of 22% in the yeast estrogenic assay. Using effect directed analysis, treated and untreated OSPW were fractionated by solid phase extraction and the fractions with the largest decrease in toxicity and estrogenicity were selected for analysis by electrospray ionization combined with linear ion trap and a high-resolution Orbitrap mass spectrometer (negative ion mode)...
