introduction: functional dyspepsia and digestive disorders are common, debilitating and costly. little information is available about the role of stress management in terms of cognitivebehavioral treatment of dyspepsia. the purpose of this study was to investigate the effectiveness of cognitive-behavioral stress management on functional dyspepsia symptoms in patients who referred to digestion c...

Background: It is important to use reliable, valid, and responsive instruments to assess the treatment outcomes. The functional rating index (FRI) is a patient reported outcome measure to assess the pain and function in patients with neck and low back pain. The FRI has been translated and culturally adapted into Persian language. The purpose of this study was to investigate the responsiveness o...

Background: Clinicians and researchers commonly use responsive outcome measures to interpret changes in a patient's condition as a result of an intervention. This study was conducted to assess the ability of the Persian version of Neck Disability Index and Functional Rating Index to detect responsiveness in the patients with neck pain.Methods: A diagnostic accuracy study was done in Ahvaz, Iran...

A recently proposed general density functional for asymptotic van der Waals forces is used to calculate van der Waals coefficients and reference-plane positions for realistic low-indexed Al surfaces. Results are given for a number of atoms and molecules outside the surfaces, as well as for the interaction between the surfaces themselves. The densities and static image-plane positions that are n...
