Published 1996Staff ViewISSN: 1089-7674Source: AIP Digital ArchiveTopics: PhysicsNotes: Improvements in tokamak transport have recently been obtained in a variety of operational modes through the formation of transport barriers, or good confinement radial zones. Here global nonlinear three-dimensional toroidal gyrokinetic simulation is used to study three effects that are linearly stabilizing and may cause the formation of transport barriers, namely, sheared toroidal rotation, reversed magnetic shear, and peaked density profiles. The effect of toroidal shear flow on ion heat diffusivity is found to be relatively weak compared to mixing-length expectations based on linear calculations. In contrast, it is found that weak or negative magnetic shear (s〈1/2) in combination with a peaked density profile relative to the temperature profile greatly suppresses ion-temperature-gradient-driven turbulence in the central region of global nonlinear simulations. Similar features are seen experimentally in reversed magnetic shear tokamak plasmas. There is some nonlocal penetration (∼20–30ρi) of the turbulence into the subcritical core region. © 1996 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

ISSN: 1439-0264Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: The cecal surface epithelium of cattle was lined entirely by columnar cells except near the openings of the glands where a few partially depleted goblet cells were encountered. Surface columnar cells with pale cytoplasm, indented (sometimes dome-shaped) apical border and irregular microvilli, were also found near the gland orifices. Surface columnar cells -near the openings of the glands contained large cytoplasmic vacuoles and lysosomal-like bodies. Near the extrusion zone, however, the columnar cells contained highly indented and apically displaced nuclei. The glands were usually long and straight and lined by an epithelium concisting mainly of undifferentiated and goblet cells. There were few entero-endocrine and non-epithelial cells (intra-epithelial lymphocytes and globule leukocytes). Paneth cells were absent.The undifferentiated cells contained many free ribosomes and apical secretory granules. Some of these cells were undergoing mitotic division. Goblet cells exhibited a typical brandy-glass appearance and showed dark and light mucigenous granules. Endocrine cells with polymorphic secretory granules and cells with more uniform secretory granules were identified in the basal part of the epithelium. Globule leukocytes and intra-epithelial lymphocytes were usually encountered near the basal part of the epithelium.The lamina propria was highly cellular. It contained many plasma cells, mast cells and small lymphocytes, and few eosinophils, neutrophils and globule leukocytes. Some of the plasma cells contained large, dense Russell bodies within the cisternae of the rough-surfaced endoplasmic reticulum. The neutrophils displayed distinct populations of small and large cytoplasmic granules. Some of the eosinophilic granules showed narrow crystalline cores. Large lymphocytes were found in the lamina propria, but occurred less frequently than small lymphocytes.Type of Medium: Electronic ResourceURL: -

ISSN: 1365-2036Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: : Prebiotic carbohydrates selectively stimulate the growth of bifidobacteria and lactobacilli in the human colon. These bacteria form part of the gut’s inherent defence against invading pathogens.〈section xml:id="abs1-2"〉〈title type="main"〉Aim: To test the effectiveness of fructo oligosaccharides in preventing travellers’ diarrhoea.〈section xml:id="abs1-3"〉〈title type="main"〉Methods: A total of 244 healthy subjects, travelling to high and medium risk destinations for travellers’ diarrhoea, took part in a randomized, double-blind, placebo-controlled study. The protocol comprised a preliminary week for recording bowel habit by diary, a 2-week pre-holiday period with the diary and consumption of 10 g of fructo oligosaccharides or placebo daily, followed by a 2-week holiday with continuation of treatment and diary. A post-study questionnaire was completed by all subjects on their return to the UK.〈section xml:id="abs1-4"〉〈title type="main"〉Results: The consumption of fructo oligosaccharides led to a small (6%; P 〈 0.02) increase in stool frequency in the pre-holiday period and gave a significantly better sense of ‘well-being’ during the holiday, although subjects reported more flatulence. There were non-significant decreases in episodes of diarrhoea with 20% on placebo and 11% on fructo oligosaccharides recording episodes in the post-study questionnaire (P=0.08) and 46% placebo, 38% fructo oligosaccharides recording episodes in the diary (P 〉 0.1). No change in bowel frequency, consistency or stool size was recorded.〈section xml:id="abs1-5"〉〈title type="main"〉Conclusion: Travel to high risk areas increases diarrhoea. Fructo oligosaccharides alone are not sufficient to prevent this, although do have some benefits for the subjects.Type of Medium: Electronic ResourceURL: -

Published 2005Staff ViewISSN: 1365-2036Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Background : We performed an audit of methotrexate for ulcerative colitis, because efficacy is unclear.Aim : To investigate the role of methotrexate in the management of ulcerative colitis.Methods : Patients with ulcerative colitis treated with oral methotrexate at the inflammatory bowel disease clinics of Oxford and Wycombe General Hospital, UK, were evaluated. Efficacy was defined by remission (complete steroid withdrawal for 〉3 months) and response (good, partial or nil, proportionate reduction of steroids).Results : There were 50 patients (42 ulcerative colitis alone; eight had rheumatoid arthritis associated with ulcerative colitis and were analysed separately). Indications for methotrexate in ulcerative colitis alone were azathioprine intolerance (31 of 42) and lack of benefit from azathioprine (11 of 42). The mean dose of methotrexate in ulcerative colitis alone was 19.9 mg/week for a median of 30 weeks (range: 7–395). Remission occurred in 42%. The response was good in 54% and partial in 18%. Side-effects occurred in 23%; 10% stopped treatment because of side-effects. Of those treated with methotrexate because of treatment failure with azathioprine, three of 11 achieved remission, but four came to colectomy within 90 days of starting methotrexate. The colitis remained in remission in seven of eight of those with RA treated with methotrexate and ulcerative colitis (mean dose 15.0 mg/week).Conclusion : Oral methotrexate (approximately 20 mg/week) is well-tolerated and moderately effective in steroid-dependent or steroid-refractory patients with ulcerative colitis.Type of Medium: Electronic ResourceURL: -
