Deep enteroscopy with a conventional colonoscope: initial multicenter study by using a through-the-scope balloon catheter system. - Gastrointestinal endoscopy
The advent of capsule endoscopy has revolutionized evaluation of the small bowel. Capsule endoscopy has become the criterion standard as the initial examination to diagnose small-bowel abnormalities, but does not allow for tissue sampling or therapeutic intervention. Deep enteroscopy can be performed by using a balloon-assisted device or a spiral overtube for both diagnostic and therapeutic interventions of the small bowel. Deep enteroscopy is time-consuming and requires special endoscopes and accessories to perform the examination. We studied a novel through-the-scope balloon catheter system used for deep enteroscopy that uses a conventional colonoscope and standard accessories.We performed a 9-center, retrospective study using a novel TTS balloon system for small-bowel evaluation. The new through-the-scope device is an on-demand balloon catheter that is inserted through the instrument channel of a standard colonoscope and enables deep advancement into the small bowel in either the anterograde or retrograde approach. It consists of a balloon inflation/deflation system and a single-use balloon catheter designed for anchoring in the small bowel. The balloon is inflated to an anchoring pressure in the small intestine, and a repetitive push-pull technique is performed, with the endoscope sliding over the guiding catheter to the inflated balloon. The catheter may be removed and reinserted to allow for therapeutic intervention while maintaining the endoscope position.A total of 98 patients were included; 52% were male, and the mean age was 55 years old (range 15-94 years). Indications included abdominal pain, iron-deficiency anemia, occult GI bleeding, diarrhea, abnormal capsule endoscopy, weight loss, protein losing enteropathy, retained foreign body, altered anatomy ERCP, and small-bowel strictures. Anterograde enteroscopy was performed in 65 patients. The average depth of insertion was 158 cm (range 50-350 cm) from the pylorus. Retrograde enteroscopy was performed in 33 cases. The average depth of insertion was 89 cm (range 20-150 cm) beyond the ileocecal valve. Overall, diagnostic yield was 44%. The average advancement time for the anterograde and retrograde enteroscopy cases was 15.5 minutes. There were no procedural adverse outcomes reported in the 98 cases.The TTS advancing balloon is a safe and effective way to perform deep enteroscopy by using a conventional colonoscope without the need for an overtube. Procedure time is shorter than that of other forms of deep enteroscopy. Diagnostic yield and depth of insertion are on par with other forms of deep enteroscopy. This is the largest reported study using this novel technology to diagnose and treat small-bowel disease.Copyright © 2015 American Society for Gastrointestinal Endoscopy. Published by Elsevier Inc.

Early gastric cancer and dysplasia. - Gastrointestinal endoscopy clinics of North America
Since the concept of early gastric cancer was first described in Japan in 1962, its treatment has evolved from curative surgical resection to endoscopic resection, initially with polypectomy to more recently with endoscopic submucosal dissection. As worldwide experience with these endoscopic techniques evolve and gain acceptance, studies have confirmed its comparable effectiveness with historical surgical outcomes in carefully selected patients. The criteria for endoscopic resection have expanded to offer more patients improved quality of life, avoiding the morbidity and mortality associated with surgery. This article summarizes the evolutional role of endoscopic and surgical therapy in early gastric cancer.Copyright © 2013 Elsevier Inc. All rights reserved.
Disruption of a Novel NADH-Glutamate Synthase2 Gene Caused Marked Reduction in Spikelet Number of Rice. - Frontiers in plant science
Inorganic ammonium ions are assimilated by a coupled reaction of glutamine synthetase and glutamate synthase (GOGAT). In rice, three genes encoding either ferredoxin (Fd)-GOGAT, NADH-GOGAT1, or NADH-GOGAT2, have been identified. OsNADH-GOGAT2, a newly identified gene, was expressed mainly in fully expanded leaf blades and leaf sheaths. Although the distinct expression profile to OsNADH-GOGAT1, which is mainly detected in root tips, developing leaf blades, and grains, was shown in our previous studies, physiological role of NADH-GOGAT2 is not yet known. Here, we isolated retrotransposon mediated-knockout mutants lacking OsNADH-GOGAT2. In rice grown under paddy field conditions, disruption of the OsNADH-GOGAT2 gene caused a remarkable decrease in spikelet number per panicle associated with a reductions in yield and whole plant biomass, when compared with wild-type (WT) plants. The total nitrogen contents in the senescing leaf blade of the mutants were approximately a half of the WT plants. Expression of this gene was mainly detected in phloem companion cells and phloem parenchyma cells associated with large vascular bundles in fully expanded leaf blades, when the promoter region fused with a β-glucuronidase gene was introduced into the WT rice. These results suggest that the NADH-GOGAT2 is important in the process of glutamine generation in senescing leaves for the remobilization of leaf nitrogen through phloem to the panicle during natural senescence. These results also indicate that other GOGATs, i.e., NADH-GOGAT1 and ferredoxin-GOGAT are not able to compensate the function of NADH-GOGAT2.
Fine-mapping of qRL6.1, a major QTL for root length of rice seedlings grown under a wide range of NH4(+) concentrations in hydroponic conditions. - TAG. Theoretical and applied genetics. Theoretische und angewandte Genetik
Root system development is an important target for improving yield in cereal crops. Active root systems that can take up nutrients more efficiently are essential for enhancing grain yield. In this study, we attempted to identify quantitative trait loci (QTL) involved in root system development by measuring root length of rice seedlings grown in hydroponic culture. Reliable growth conditions for estimating the root length were first established to renew nutrient solutions daily and supply NH4(+) as a single nitrogen source. Thirty-eight chromosome segment substitution lines derived from a cross between 'Koshihikari', a japonica variety, and 'Kasalath', an indica variety, were used to detect QTL for seminal root length of seedlings grown in 5 or 500 microM NH4(+). Eight chromosomal regions were found to be involved in root elongation. Among them, the most effective QTL was detected on a 'Kasalath' segment of SL-218, which was localized to the long-arm of chromosome 6. The 'Kasalath' allele at this QTL, qRL6.1, greatly promoted root elongation under all NH4(+) concentrations tested. The genetic effect of this QTL was confirmed by analysis of the near-isogenic line (NIL) qRL6.1. The seminal root length of the NIL was 13.5-21.1% longer than that of 'Koshihikari' under different NH4(+) concentrations. Toward our goal of applying qRL6.1 in a molecular breeding program to enhance rice yield, a candidate genomic region of qRL6.1 was delimited within a 337 kb region in the 'Nipponbare' genome by means of progeny testing of F2 plants/F3 lines derived from a cross between SL-218 and 'Koshihikari'.
Reverse genetics approach to characterize a function of NADH-glutamate synthase1 in rice plants. - Amino acids
Rice plants grown in anaerobic paddy soil prefer to use ammonium ion as an inorganic nitrogen source for their growth. The ammonium ions are assimilated by the coupled reaction of glutamine synthetase (GS) and glutamate synthase (GOGAT). In rice, there is a small gene family for GOGAT: there are two NADH-dependent types and one ferredoxin (Fd)-dependent type. Fd-GOGAT is important in the re-assimilation of photorespiratorily generated ammonium ions in chloroplasts. Although cell-type and age-dependent expression of two NADH-GOGAT genes has been well characterized, metabolic function of individual gene product is not fully understood. Reverse genetics approach is a direct way to characterize functions of isoenzymes. We have isolated a knockout rice mutant lacking NADH-dependent glutamate synthase1 (NADH-GOGAT1) and our studies show that this isoenzyme is important for primary ammonium assimilation in roots at the seedling stage. NADH-GOGAT1 is also important in the development of active tiller number, when the mutant was grown in paddy field until the harvest. Expression of NADH-GOGAT2 and Fd-GOGAT in the mutant was identical with that in wild-type, suggesting that these GOGATs are not able to compensate for NADH-GOGAT1 function.
[Application of simultaneous determination method of residual veterinary drugs to processed foods]. - Shokuhin eiseigaku zasshi. Journal of the Food Hygienic Society of Japan
To ensure the safety of processed foods, we developed a method for simultaneous determination of residual veterinary drugs in some processed foods. Eighty-nine compounds were selected for the analysis based on reports of illegal use of the veterinary drugs and our research information. In our LC/MS/MS system, an Atlantis C(18) column, which could separate a wide range of compounds, was used with a gradient system of 0.1% formic acid-acetonitrile containing 0.1% formic acid as the mobile phase. Sharp and symmetrical peaks with sufficient signal intensity were obtained. In this system, the recovery rates of detected veterinary drugs in processed foods were mostly in the range of 60-120%. Therefore, it is considered that this method is suitable for screening of residual veterinary drugs in processed foods.
Effects of alpha-glucosylhesperidin, a bioactive food material, on collagen-induced arthritis in mice and rheumatoid arthritis in humans. - Immunopharmacology and immunotoxicology
Hesperidin (Hsp) is an abundant flavonoid in citrus fruits, and the oral administration of Hsp has been recently reported to suppress collagen-induced arthritis in mice. Therefore, we sought to determine whether alpha-glucosylhesperidin (Hsp-G), which is an Hsp derivative with enhanced water-solubility, is effective on treating arthritis in both mice and humans. Hsp-G was orally administered to mice with collagen-induced arthritis, and its effects were evaluated clinically and histologically. Oral administration of Hsp-G improved collagen-induced arthritis when administered before the onset of arthritis as well as when administered after its onset. A decrease in tumor necrosis factor-alpha production was found to cause this improvement. In the human study, 19 patients with rheumatoid arthritis (RA) were enrolled in a 12-week double-blind, placebo-controlled trial. Patients were administered beverages containing 3 g Hsp-G (n = 9) or placebo (n = 10) every morning for the duration of the 3-month trial. Additionally, patients received standard therapy from a physician every 4 weeks. As a result, 3 of 9 patients in the Hsp-G group improved, while only 1 of 10 patients in the placebo group improved; this was in accordance with the American College of Rheumatology criteria. The present study revealed that the food material Hsp-G was effective when administered with standard anti-rheumatoid therapy in ameliorating RA in mice and humans without any adverse effects and may improve the quality of life for patients with RA as a complementary/alternative medicine.
