Obesity is considered the most important public health problem. Previous studies have confirmed that a high-fat diet (HFD) can cause the development of systemic and tissue inflammation due to the increase in pro-inflammatory markers.

This study aims to evaluate the effect of aerobic exercise and pistachio soft hull extract (PSHE) on inflammatory gene expression in the soleus muscle of rats fed a HFD.

In an experimental trial, 30 female Wistar rats weighing between 180 and 200 grams were selected as subjects and randomly divided into five groups: Normal diet control, HFD control, HFD aerobic exercise, HFD-PSHE, and HFD aerobic exercise-PSHE. The aerobic exercise program consisted of four weeks of five weekly sessions of running on a treadmill at an intensity of 50 – 60% VO 2max . Pistachio soft hull extract at a dose of 60 mg/kg was administered to the rats by gavage for four weeks, five times a week. Forty-eight hours after the last interventions, the rats were anesthetized, and the soleus muscle was removed to determine the expression of the IL-6 and IL-1β genes.

Induction of HFD significantly decreased IL-6 (P = 0.001) and increased IL-1β (P = 0.001) gene expression. IL-1β gene expression in the aerobic exercise (P = 0.001), PSHE (P = 0.003), and aerobic exercise-PSHE (P = 0.001) groups was significantly lower than in the HFD control group. Aerobic exercise (P = 0.002), PSHE (P = 0.002), and the combination of aerobic exercise and PSHE (P = 0.003) caused a significant increase in IL-6 gene expression compared to the HFD control group.

High-fat diet promotes inflammation in skeletal muscle by increasing the expression of the IL-1β and IL-6 genes. Aerobic exercise, PSHE, and the combination of aerobic exercise and PSHE can exert their anti-inflammatory effects by reducing the expression of the IL-1β and IL-6 genes in skeletal muscle tissue.

 Incomprehensive studies have examined the therapeutic and side effects of curcumin on the treatment of debilitating diseases, such as Rheumatoid Arthritis (RA). This study aimed to explore the anti-inflammatory effects of curcumin on RA.

 This double-blind clinical trial was carried out on 64 RA patients with an erythrocyte sedimentation rate (ESR)-Disease Activity Score (DAS)-28>2.6. The patients were then randomly divided into two groups of intervention and control. In addition to the routine treatment, the intervention group was treated with 80-mg/day capsules of curcumin (nano-micelles). Further, the patients were followed up for three months, and clinical-laboratory examinations were recorded in this study.

 There was no significant difference between the intervention and control groups regarding the trends of the disease activity indicators, including DAS-28, disability index, physician assessment, and the number of tender joints (P>0.05). Further, a significant difference was found between the two groups in terms of pain score changes and the number of swollen joints. Additionally, the curcumin-treated subjects obtained lower mean pain and fewer swollen joints, compared to those in the control group (P<0.05).

 The present study revealed that curcumin had no significant therapeutic effects on reducing the activity of RA; however, no significant side effects were observed on the patients, and it also showed its analgesic effect well.
