Aspects of the non-pharmacological treatment of irritable bowel syndrome

World Journal of Gastroenterology 2015年第40期21卷 11439-11449页

作者： Elsa Maria Eriksson Kristina Ingrid Andrén Goran Karl Kurlberg Henry Ture Eriksson Department of Functional Gastroenterology Pavilion 2Sahlgrenska University Hospital/Ostra

Irritable bowel syndrome(IBS) is one of the most commonly diagnosed gastrointestinal conditions. It represents a significant healthcare burden and remains a clinical challenge. Over the years IBS has been described from a variety of different perspectives; from a strict illness of the gastrointestinal tract(medical model) to a more complex multi-symptomatic disorder of the brain-gut axis(biopsychosocial/psychosomatic model). In this article we present aspects of the pathophysiology and the non-pharmacological treatment of IBS based on current knowledge. Effects of conditioned stress and/or traumatic influences on the emotional system(top-down) as well as effects on the intestine through stressors,infection,inflammation,food and dysbiosis(bottom-up) can affect braingut communication and result in dysregulation of the autonomic nervous system(AnS),playing an important role in the pathophysiology of IBS. Conditioned stress together with dysregulation of the autonomic nervous system and the emotional system may involve reactions in which the distress inside the body is not recognized due to low body awareness. This may explain why patients have difficulty identifying their symptoms despite dysfunction in muscle tension,movement patterns,and posture and biochemical functions in addition to gastrointestinal symptoms. IBS shares many features with other idiopathic conditions,such as fibromyalgia,chronic fatigue syndrome and somatoform disorders. The key to effective treatment is a thorough examination,including a gastroenterological examination to exclude other diseases along with an assessment of body awareness by a body-mind therapist. The literature suggests that early interdisciplinary diagnostic cooperation between gastroenterologists and body-mind therapists is necessary. re-establishing balance in the AnS is an important component of IBS treatment. This article discusses the current knowledge of body-mind treatment,addressing the topic from a practical point of view

Study of structural,electrical and optical properties of vanadium oxide condensed films deposited by spray pyrolysis technique

引用

Advances in Manufacturing 2013年第4期1卷 320-328页

作者： M.Mousavi A.Kompany n.Shahtahmasebi M.M.Bagheri-Mohagheghi Department of Physics Ferdowsi University of Mashhad nanoscience Center Ferdowsi University of Mashhad School of Physics Damghan University

Vanadium oxides condensed films are prepared on glass substrates, using spray pyrolysis （SP） technique. The effects of substrate temperature, vanadium concentra- tion in initial solution and the solution spray rate on the nano-structural, electrical, and optical properties of depos- ited films were investigated. Characterizations of the sam- ples were performed using X-ray diffraction （XrD）, scanning electron microscopy （SEM）, and UV-Vis spec- troscopy methods. The type and concentration of the charge carriers were determined and measured by Hall effect experiment. XrD patterns showed that the prepared films had polycrystalline structure, mostly tetragonal fl-V205 and V409 phases with the preferred orientation along （200） direction. The Hall effect experiment revealed that all samples were n-type, except the ones deposited at substrate temperatures Tsub ： 300 ~C and Tsub = 450 ~C, vanadium concentration 0.1 mol/L and solution spray rate 10 mL/min. The charge carrier concentrations obtained were in the range 1016-1018 cm-3. The lowest sheet resistance （r~） was obtained for the samples prepared at T^ub = 450 ~C, vana- dium concentration 0.05 mol/L and solution spray rate 10 mL/min. It was also found that the optical transparency of the samples changed from 20% to 75% and the optical bandgap of the samples was from 2.22 eV to 2.58 eV, depending on the deposition conditions.
