Comparison of the Effectiveness of Mindfulness-Based Stress Reduction and Compassion-Focused Treatment on the Severity of Gastrointestinal Symptoms in Patients with Irritable Bowel Syndrome.

Background: The aim of this research was to compare the effectiveness of mindfulness-based stress reduction and compassion-focused on the severity of digestive symptoms in patients with irritable bowel syndrome (IBS).

Methods: The research method was of semi-experimental type with pre-test, post-test, follow-up, and experimental and control groups. The population included patients with IBS in Isfahan city, 45 of them were selected by convenience sampling method and randomly assigned to three groups (15 in each group).

Comparison of the Effectiveness of Mindfulness-Based Stress Reduction and Compassion-Focused Therapy on the Cognitive Emotion Regulation in Patients with Irritable Bowel Syndrome.

We aimed to compare the effectiveness of mindfulness-based stress reduction and compassion-focused on the cognitive regulation of emotion in patients with irritable bowel syndrome (IBS). The research method was the semi-experimental type, with pre-test, post-test, follow-up, and experimental and control groups. The population included patients with IBS in Isfahan city; 45 of them were selected by convenience sampling method and randomly assigned to 3 groups (15 in each group).

Ultrasmall cerium oxide nanoparticles as highly sensitive X-ray contrast agents and their antioxidant effect.

Owing to their theranostic properties, cerium oxide (CeO) nanoparticles have attracted considerable attention for their key applications in nanomedicine. In this study, ultrasmall CeO nanoparticles (particle diameter = 1-3 nm) as X-ray contrast agents with an antioxidant effect were investigated for the first time. The nanoparticles were coated with hydrophilic and biocompatible poly(acrylic acid) (PAA) and poly(acrylic acid--maleic acid) (PAAMA) to ensure satisfactory colloidal stability in aqueous media and low cellular toxicity.

Comparing the Effectiveness of Cognitive-Behavioral Therapy and Brief Intervention on Relapse Prevention among Drug Users.

Background: This study aimed to compare the effectiveness and stability of group cognitive-behavioral therapy (CBT) and brief intervention (BI) for relapse prevention (RP) among drug users of drop-in-centers (DICs) in Ahvaz, Iran.

Methods: The present study was a quasi-experimental one with a pretest-posttest design, a follow-up phase, and a control group. The statistical population included all drug users of drop- in-centers of Ahvaz in 2021.

Facile Synthesis and X-ray Attenuation Properties of Ultrasmall Platinum Nanoparticles Grafted with Three Types of Hydrophilic Polymers.

Ultrasmall platinum nanoparticles (Pt-NPs) grafted with three types of hydrophilic and biocompatible polymers, i.e., poly(acrylic acid), poly(acrylic acid-co-maleic acid), and poly(methyl vinyl ether-alt-maleic acid) were synthesized using a one-pot polyol method.
