Abstract
Introduction: Since time memorial, herbal medicine has played an important role for relief of various symptoms including pain relief. Many researches have focused on the curative as well as antinociceptive effects of herbal extracts. Cinnamon Zeylanicum has long been prescribed in traditional medicine for the treatment of inflammatory-related diseases such as rheumatisms, bronchitis and muscle pains. However, there is little if any scientific research indicating this effect
Methods: This experimental study was carried out in Shaheed Sadoughi Medical School on 25 Wistar Rats (200-300grams) randomly divided into 5 groups. In this study, the analgesic effect of intraperitoneal administration of hydro-alcoholic Cinnamon extract in different doses (50,100,500mg/kg) was assessed by using Formalin Test (for chronic pain) during 1hr. post Formalin injection.
Results: Our results indicated that cinnamon extract in high dose (500mg/kg) decreased the chronic pain intensity in the 2nd phase of formalin test. This analgesic effect was significant (P<0.001) as compared with sham group, but the lower doses (50 &100mg/kg) of cinnamon extract did not show any analgesic effect on chronic pain in Formalin Test.
Conclusion: Data from this study confirms the analgesic effect of high doses (500mg/kg) of cinnamon extract on chronic pain in Formalin Test which may be due to anti-inflammatory effect of this plant material.

Abstract
Over the past decades, progression in genetic element manipulation, and consequently, the treatment of diseases has been remarkable. It is worth noting that these genetic manipulations perform at different levels, including DNA and RNA. The earlier genomic editing techniques, including MN, ZFN , TALEN , performing their functions by creating double-stranded breaks (DSBs), and after breakage, the cell tries to repair the breakage through two systems, homologous recombination and non-homologous end joining. CRISPR/Cas technology has been discovered recently, and has become the most widely used genome-editing tool, mainly due to its capabilities and those added to this through the genetic engineering. In this study, we aimed to introduce a variety of CRISPR classes in the elementary parts, and then the modified CRISPR systems developed to increase the efficiency and specificity of the system and provide acceptable results will be introduced.
In this study, for three months in the fall and winter, Pubmed and Web of science sites searched for keywords such as CRISPR, Types of CRISPR, gRNA, Cas9, and CRISPR-Cas9 nickase that eventually resulted in about four hundred Sixty-one articles, and some of these articles after closer study, reviewed in this article.
Genetic engineering techniques have successfully transformed this system into the most efficient genome editing tool in recent years. Researchers are working on a system to treat various diseases by resolving problems such as high specificity, cutting off non-target sites, how to move to a cell, and setting up a proper repair system.

Abstract
Introduction: Biomarkers would significantly improve the early detection of the disease and identification of individuals at risk of emerging complications. Diabetes mellitus is a group of diverse and complex metabolic disorders. Both type 1 diabetes (T1D) and type 2 diabetes (T2D) mellitus are associated with distinct alterations in the profile of MicroRNAs (miRNAs) in the blood, which are sometimes detectable several years before the disease manifests. Lately, considerable attention has been paid to the role of miRNAs as biomarkers for T2D. The aim of this study was to review the expression of different miRNAs in pre-diabetic (per-T2D), T2D and healthy groups.
Conclusion After evaluating several articles, including main articles, meta-analysis and review studies, it was found that the expression of micRNAs was statistically different in healthy, pre-T2D and T2D groups. In addition, the expression of specific miRNAs is useful in preventing disease and modifying gene structure.
This study indicated that the plasma expression level of miRNAs could be considered as a non-invasive and fast tool for the separation of pre-T2D individuals from their healthy counterparts.
