    (Iranian Association of Pharmaceutical Scientists, 2025) Eslami, Zahra; Fallah, Ayda; Eghbal Moghanlou, Abdorreza; Baydaş, Giyasettin; Sharifian, Shohreh; Mirghani, Seyed Javad
    Obesity, caused by an inequality between energy production and consumption, is characterized by lipid accumulation in adipose tissues. Currently, around 650 million adults and roughly 340 million children and adolescents (aged 5-19 years) are affected by obesity. This condition tends to be more common among women and older populations. It is imperative to develop uncomplicated therapeutic approaches to prevent obesity-related metabolic diseases in conjunction with lifestyle modifications. Forty-three rats were randomly divided into five groups: 1. normal diet (ND), 2. High-fat diet (HFD), 3. HFD + adenosine, 4. HFD + High-intensity interval training (HIIT) + adenosine, and 5. HFD + HIIT. Gene expression of CGI-58, HSL, and AMPK in subcutaneous adipose tissues and serum level of glucose, insulin, Homeostatic Model Assessment for Insulin Resistance (HOMA-IR), free fatty acid (FFA), and lipid profile (Triglyceride (TG), Total cholesterol (TC), Low density lipoprotein (LDL), High density lipoprotein (HDL), and Very low density lipoprotein (VLDL)) were assessed. The rats were fed HFD-induced obesity for 13 weeks. Following, adenosine 0.2 mg/ml/kg and 0.4 mg/ml/kg, as well as HIIT, were administered over 12 weeks. CGI-58, HSL and AMPK gene expression showed significant expression in all groups. HFD+HIIT+adenosine, HFD+adenosine, and HFD+HIIT groups significantly increased all genes. Conversely, FFA and glucose serum levels were significantly reduced in intervention groups. Insulin had higher serum levels in ND, HFD + adenosine, and HFD+HIIT groups, and adenosine caused decreased glucose. Also, favorable effects of HIIT and adenosine on lipid profile were observed. HIIT and adenosine can affect lipid metabolism, improve insulin resistance, and increase lipolysis in adipose tissue. Furthermore, adenosine can boost the effect of HIIT on gene expression, triggering lipolysis to prevent obesity. © 2025, Iranian Association of Pharmaceutical Scientists. All rights reserved.

    Endurance Training and Exogenous Adenosine Infusion Mitigate Hippocampal Inflammation and Cell Death in a Rat Model of Cerebral Ischemia/Reperfusion Injury: A Randomized Controlled Trial
    (Briefland, 2022) Eslami, Zahra; Ghomi, Masoumeh Rezaei; Saidi, Aref; Mousavi, Seyedeh Vafa; Farhadi, Mahboubeh; Robati, Najmeh Sheikh; Moghanlou, Abdorreza Eghbal
    Background: Cerebral ischemia can cause irreversible structural and functional damages to the brain, especially to the hippocampus. Preconditioning with endurance training and endogenous adenosine infusion may reduce ischemia-associated damages. Objectives: This study aimed to evaluate the effect of preconditioning with endurance training and endogenous adenosine infusion on cell death in the hippocampal CA1 region following ischemia/reperfusion injuries in a rat model. Methods: Male Wistar rats were divided into five groups: (1) control (n = 8); (2) ischemia (n =12); (3) endurance training + ischemia (n = 12); (4) adenosine infusion + ischemia (n =12); and (5) endurance training + adenosine infusion + ischemia (n =12). The rats in the training groups ran on a treadmill five days per week for eight weeks. In the adenosine infusion groups, the rats were injected 0.1 mg/mL/kg of adenosine intraperitoneally. Also, in the ischemic groups, both common carotid arteries were clamped for 45 minutes. Cresyl violet staining and real-time polymerase chain reaction (PCR) assay were used to evaluate cell death and cytokine gene expression, respectively. Results: Based on the present results, treatments, including endurance training + ischemia, adenosine infusion + ischemia, and endurance training + adenosine infusion + ischemia reduced the level of interleukin-6 (IL-6) and glutamate gene expression, respectively, compared to the group of ischemia only. In contrast, the expression of nerve growth factor (NGF) and adenosine receptor (A2A) genes increased by seven, four, and two folds in the endurance training + ischemia, adenosine infusion + ischemia, and endurance training + adenosine infusion + ischemia groups, respectively, compared to the group of ischemia only. Conclusions: Endurance training on a treadmill and exogenous adenosine infusion synergistically diminished cell death and reduced the expression of pro-inflammatory cytokines, while promoting the neurotrophic factor expression. When endurance training and adenosine infusion were used as stimulants before the induction of cerebral ischemia, they significantly reduced cell death.
