The biocompatibility and potential application of graphene\u2010based nanomaterials in biomedicine have been documented. The effects of polyethylene glycol\u2010graphene quantum dots (GQDs\u2010PEG) on cardiac function in rats with myocardial infarction (MI) were examined.\n                    <jats:italic>Methods<\/jats:italic>\n                    . Wistar rats were randomly assigned to two main groups, each consisting of sham\u2010Veh., MI\u2010Veh., and MI+GQDs\u2010PEG at doses of 5, 10, and 20\u2009mg\/kg. MI was induced by the closure of the left anterior descending (LAD) coronary artery. After MI, GQDs\u2010PEG were injected at different doses IP every other day for two weeks. In the end, hemodynamic and heart contractility indices were assessed. The levels of myocardial MDA (malondialdehyde), SOD (superoxide dismutase), GPX (glutathione peroxidase), and TAC (total antioxidant capacity) were measured by the ELISA method. The serum ALP, ALT, AST, creatinine, and urea levels were measured using the photometric method. The infarct size was assessed by TTC staining.\n                    <jats:italic>Results<\/jats:italic>\n                    . GQDs\u2010PEG decreased the infarct size at doses of 10 and 20\u2009mg\/kg and recovered the MI\u2010induced reductions of +dp\/dt max and \u2010dp\/dt max in the study groups. GQDs\u2010PEG normalized systolic blood pressure and left ventricular systolic pressure reduction at the dose of 20\u2009mg\/kg in the MI group. Heart SOD, GPX, and TAC increased in the GQDs\u2010PEG 10 and 20 groups. Almost no signs of toxic effects due to GQDs\u2010PEG administration were observed on the liver and kidneys.\n                    <jats:italic>Conclusions<\/jats:italic>\n                    . The results provided clear evidence that GQDs\u2010PEG improve cardiac performance and hemodynamic parameters in rats with MI by reducing oxidative stress. GQDs\u2010PEG is proposed as a therapeutic target for the treatment of MI.\n                  <\/jats:p>","DOI":"10.1155\/2021\/8569225","type":"journal-article","created":{"date-parts":[[2021,11,20]],"date-time":"2021-11-20T13:35:07Z","timestamp":1637415307000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["PEGylated Graphene Quantum Dot Improved Cardiac Function in Rats with Myocardial Infarction: Morphological, Oxidative Stress, and Toxicological Evidences"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7879-9938","authenticated-orcid":false,"given":"Farzaneh","family":"Rostamzadeh","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5594-2447","authenticated-orcid":false,"given":"Mitra","family":"Shadkam-Farrokhi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4694-8174","authenticated-orcid":false,"given":"Saeideh","family":"Jafarinejad-Farsangi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8030-8704","authenticated-orcid":false,"given":"Hamid","family":"Najafipour","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9963-7383","authenticated-orcid":false,"given":"Zeinab","family":"Ansari-Asl","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7148-5568","authenticated-orcid":false,"given":"Mahboobeh","family":"Yeganeh-Hajahmadi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2021,11,20]]},"reference":[{"key":"e_1_2_10_1_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(12)60075-0"},{"key":"e_1_2_10_2_2","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.119.043100"},{"key":"e_1_2_10_3_2","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/eht356"},{"key":"e_1_2_10_4_2","doi-asserted-by":"publisher","DOI":"10.3390\/molecules25092193"},{"key":"e_1_2_10_5_2","doi-asserted-by":"publisher","DOI":"10.2217\/nnm-2018-0018"},{"key":"e_1_2_10_6_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.1246736"},{"key":"e_1_2_10_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.mtcomm.2021.102559"},{"key":"e_1_2_10_8_2","doi-asserted-by":"publisher","DOI":"10.1139\/cjpp-2018-0225"},{"key":"e_1_2_10_9_2","doi-asserted-by":"publisher","DOI":"10.1038\/nnano.2007.223"},{"key":"e_1_2_10_10_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.HYP.0000254415.31362.a7"},{"key":"e_1_2_10_11_2","doi-asserted-by":"publisher","DOI":"10.1074\/jbc.M209793200"},{"key":"e_1_2_10_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2004.01.036"},{"key":"e_1_2_10_13_2","doi-asserted-by":"publisher","DOI":"10.1155\/2019\/8563845"},{"key":"e_1_2_10_14_2","doi-asserted-by":"publisher","DOI":"10.1161\/hc0902.104353"},{"key":"e_1_2_10_15_2","doi-asserted-by":"publisher","DOI":"10.1126\/sciadv.aaz2630"},{"key":"e_1_2_10_16_2","doi-asserted-by":"publisher","DOI":"10.3390\/s20041072"},{"key":"e_1_2_10_17_2","doi-asserted-by":"publisher","DOI":"10.1080\/00150193.2019.1592479"},{"key":"e_1_2_10_18_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja803688x"},{"key":"e_1_2_10_19_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.diamond.2016.07.008"},{"key":"e_1_2_10_20_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.biomaterials.2014.03.021"},{"key":"e_1_2_10_21_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tiv.2020.104796"},{"key":"e_1_2_10_22_2","doi-asserted-by":"publisher","DOI":"10.1097\/FJC.0000000000000935"},{"key":"e_1_2_10_23_2","volume-title":"Measuring Infarct Size by the Tetrazolium Method","author":"Downey J.
