    Objective: Altmetric analysis is web-based a metric analysis. Social media platforms affect medical literature over the last few years. The altmetric Attention Score (AAS) is an automatically calculated metric for monitoring social media. This study aimed to determine the correlation between AAS and the number of citations received from important articles published in the last 11 years with microRNAs. Methods: MicroRNA as a search term was entered into the Web of Science database to identify all articles. The most 50 cited articles were analyzed by Topic, Journal Name, First Author, Publication Year, Citation, Average Citation Per Year (ACPY), Impact Factor (IF), Quartile (Q) Category, H Index, and AAS. Results: Altmetric explorer identified 45.911 articles as being referred to online. Correlation analysis revealed that there was a weak correlation between AAS and the number of citations (p<0.15), while a very strong correlation was found between the number of citations and ACPY (p<0.01). Conclusion: These results give some clues about the articles studied did not lose their currency. They are cited regularly each year so they are very popular in academia. This study provides a detailed list of 50 most cited microRNA articles and social media interest using the Altmetric.com database. miRNAs can be used in the diagnosis, prognosis, or treatment of various diseases.

    Pentylenetetrazole-induced kindling rat model: miR-182 and miR-27b-3p mediated neuroprotective effect of thymoquinone in the hippocampus

    Objectives: Epilepsy is a neurological disease that pathologically affects brain functions. The epileptic hippocampus has modified microRNA(miRNA) levels. Therefore, we aimed to evaluate the neuroprotective effect of thymoquinone (TQ) in PTZ-induced epilepsy and to demonstrate the overlap between miRNA and mRNA expression profiles. Methods: Male adult Wistar albino rats (200–230 g, n = 20) were divided into three groups as control (n = 6), PTZ (n = 7), and TQ + PTZ (n = 7). The PTZ kindling model was created by injecting PTZ in sub convulsive doses to rats on days 1, 3, 5, 8, 10, 12, 15, 17, 19, 22, and 24 of the study into animals. Clonic and tonic seizures were induced by injecting a convulsive dose of PTZ on day 26 of the study. Rats in the TQ+PTZ group were treated by oral gavage with a 20 mg/kg TQ 2 h before each PTZ injection. The rats in the control group were treated with 0.5 ml saline. Seizure severity was evaluated with the Racine scale. The genes and signaling pathways targeted by miRNAs were determined by bioinformatics analysis. Results: In the rat hippocampus, mature 728 miRNAs were analyzed by microarray and the nine miRNA were verified by quantitative Real-Time PCR. rno-miR-182 and rno-miR-27b-3p were up-regulated in the PTZ group and down-regulated in the TQ + PTZ group. Discussion: In the PTZ kindling epilepsy model, the expression of these two miRNAs was regulated by TQ and exerted a neuroprotective effect by controlling the activities of target genes.
