The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 2.4 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 2.8 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.5 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00049 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.59 SJR: 0.429 SNIP: 0.507 CiteScore™:: 3.9 H-Index: 49

摘要

The modifying effect of butylated hydroxytoluene (BHT) on 60Co gamma radiation and 4-nitro-quinoline 1-oxide-induced gene conversion and back mutation frequencies was investigated using diploid yeast Saccharomyces cerevisiae D7. Cells were exposed to 100 or 400 Gy in the presence of 0.025−0.25 mM BHT. BHT exhibited radioprotection and significantly reduced radiation-induced gene conversion and back mutation frequencies as well as cell killing. In another set of experiments, cells were simultaneously treated with 0.025−0.1 mM BHT and 0.5 μM 4-NQO. BHT significantly enhanced 4-NQO-induced gene conversion and back mutation frequencies. BHT post-treatment did not modify radiation-induced genetic events but enhanced 4-NQO-induced back mutation frequencies, indicating its potential to act as a tumor-promoting agent with 4-NQO.
