Omidreza Salehi

Background and objectives: Aging is a natural phenomenon associated with a decrease in physical fitness factors and increases in chronic pain. The present study aimed to investigate the effect of High Interval Intensity Training (HIIT) and Moderate Intensity Continued Training (MICT) with Citrus Aurantium (CA) consumption on pain threshold and motor balance in elderly rats.
Material and Methods: Forty-nine elderly rats were randomly divided into 1) control, 2) MICT, 3) HIIT, 4) MICT+CA, 5) HIIT+CA, 6) CA and 7) sham groups. Groups 3 and 5 performed HIIT at a speed of 25-25 m/min, and groups 2 and 4 performed MICT at a speed of 25-20 m/min; also, groups 4-6 received 300 mg/kg/day CA peritoneally. The pain and motor balance tests were evaluated using a hot plate and rotarod devices respectively. The Kolmogorov-Smirnov test was used to investigate the normal distribution of findings and one-way ANOVA with Tukey’s post- hoc tests was used to analyze of findings (P≤0.05).
Results: CA, MICT, HIIT, MICT+CA, and HIIT+CA significantly increased pain threshold and motor balance (P<0.05); MICT+CA (P<0.05) and HIIT+CA (P<0.05) significantly increased pain threshold compared to CA, MICT, and HIIT, and HIIT+CA significantly increased pain threshold compared to MICT+CA (P<0.05).
Conclusion: Although CA, MICT, and HIIT alone can enhance pain threshold and motor balance nevertheless it appears that MICT+CA and HIIT+CA have a better effect on the increase of pain threshold, so the effects of HIIT+CA can be higher than MICT+CA.

Farzaneh Taghian

Background and objectives: Zingiber officinale extract can control cardiovascular risk factors. Moreover, endurance training may effectively rehabilitate myocardial infarction by strengthening the myocardial muscle tissue. In-silico analysis identified essential genes involved in the heart damage process based on data from the DisGeNET database. Hence, we estimated the affinity of chemical and bioactive molecules for PPARγ. Therefore, this study aimed to investigate the effect of endurance exercise alone or combined with Zingiber officinale extract on Myocardial infarction rats.
Material and Methods: Twenty-five male rats were randomly divided into five groups, including (1) group of myocardial infarctions (MI) induced by subcutaneous injection of isoproterenol, (2) myocardial infarction+exercise (MI+EX), (3) myocardial infarction+Zingiber Officinale extraction administered orally (MI+GE), (4) myocardial infarction+exercise+Zingiber Officinale extract (MI+EX+GE), and (5) Control group. The qPCR-Real Time technique was used to measure the expression of PGC1-ɑ, PPARγ, and TNF-ɑ genes. We evaluated the concentration of Troponin-1 as a vital myocardial ischemia marker.
Results: In bioinformatics analysis, we found that the PPARγ, PGC1-ɑ, and TNF-ɑ pathways were critical in heart injury. Also, the effects of Zingiber officinale on heart tissue were detected through PPARγ by drug design. Endurance training combined with Zingiber officinale consumption reduced the expression of TNF-ɑ, Troponin-1 and increased the PGC1-ɑ, PPARγ genes. Furthermore, consumption of Zingiber officinale extraction improved the levels of PGC1-ɑ, PPARγ, TNF-ɑ, and Troponin-1.
Conclusion: Our data indicated that six weeks of endurance training and consumption of Zingiber officinale extract could reduce the relative expression of the TNF-ɑ and significantly increase the level of PGC1-ɑ, PPARγ.

Background: Alzheimer's is a neurodegenerative disorder characterized by memory loss and cognitive dysfunction. Research has shown that blood metal levels and physical activity may be key to injury and possibly Alzheimer's treatment. The aim of this study was to investigate the effects of high intensity interval training (HIIT) and Folate Nano-liposome on the expression of D1 and D2 receptors in the hippocampal tissue of Alzheimer's rats.
Methods: Thirty-three male Wistar rats at the age of eight weeks were prepared from Pasteur Institute. Rats were randomly divided into 5 groups (healthy control, Alzheimer's control, Alzheimer+ HIIT, Alzheimer +Folate Nano liposomes, Alzheimer+ HIIT +Folate Nano liposomes).Alzheimer's induction was performed and Folate Nano-liposomes were injected as a supplement .After the last training session, rats were anesthetized and the hippocampus was analyzed.
Results: The results of one-way ANOVA showed a significant increase between the groups in D1 mRNA and D2 mRNA (P≤0.000). The results of the Bonferroni post hoc test showed that there was a significant increase the control group and the Alzheimer's, Alzheimer's + HIIT and Alzheimer's +folate Nano liposomes. There was a significant increase between Alzheimer's group and Alzheimer's+ HIIT and Alzheimer's+ HIIT+ folate Nano-liposomes (P≤0.05).
Conclusion: Resistance training and Folate Nano-liposomes have changed the content of D1 and D2 in the brain after Alzheimer's induction. These changes may be due in part to the synergistic effect of physical activity and Nano-pharmaceuticals in preventing or reducing the detrimental effects of pathological conditions.

Background and objectives: Microleakage at the interface of tooth structure and fissure sealant plays a crucial role in failure of the treatment. This in vitro study aimed to determine the microleakage of self-adhesive flowable composite resins as pit and fissure sealants.
Material and Methods: 60 healthy extracted premolar teeth were randomly divided into the 4 groups (n=15), group 1) clinpro sealants (control), group 2) flowable composite resin with bonding agent (total-etch), group 3) flowable composite resin with self-etch bonding agent, and group 4) self-adhesive composite resin. After thermocycling the specimens were immersed in 2% methylene blue for 48 hours and then sectioned in the buccolingual direction. The microleakage was assessed by dye penetration using a stereomicroscope at 15X magnification. Data analysis was performed using SPSS version 18.0 as well as Mann-Whitney and Kruskal-Wallis tests.
Results: There was a statistically significant difference in microleakage score between the groups (P-value = 0.006). The lowest mean of microleakage level was observed in the flowable composite group with total-etch bonding (group 2) 1.26±0.96, followed by the Clinpro sealant group (group 1) 1.62±1.20, and then the self-adhesive composite group (group 4) 1.85±1.00.
Conclusion: Based on the results of this study, the microleakage of self-adhesive composite resin revealed no significant difference with conventional fissure sealant; however, the microleakage of these composite resin was higher than flowable composite resin with total-etch bonding agent.

Inducible Animal Models of Skin Fibrosis; Updated Review of the Literature

Mohsen Saeidi

Fibrosis is a common and mostly progressive pathological outcome in various chronic inflammatory disorders. Dermal (skin) fibrosis, which is associated with intense skin lesions, is a result of an uncontrolled healing process in the dermis, particularly disproportionate fibroblast proliferation and extracellular matrix (ECM) production. Animal models are substantial tools in biomedical investigations and have been considerably employed to evaluate miscellaneous features of diseases that cannot be demonstrated otherwise in humans. To date, various skin fibrosis models have been generated, including the transgene and/or genetic models and chemical and drug-induced models. However, genetic models are sophisticated and need access to convoluted methods. Accordingly, the introduction of affordable and easy to generate fibrosis models in the skin is crucial. Here, we aimed to introduce the chemical/drug-induced skin fibrosis animal models to provide an updated list of available approaches.
