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

RÉSUMÉ

9,10-Dimethyl benz(a)anthracene (DMBA), when injected intratracheally once at a dose of 20 mg/kg body weight, is found to induce lung cancer in rats. Two nonsteroidal anti-inflammatory drugs (NSAIDs), indomethacin and etoricoxib, are given orally daily as chemopreventive agents at a dose of 0.6 mg/kg body weight and 2 mg/kg body weight, respectively, along with DMBA. Morphologic and histologic analysis revealed the occurence of tumors and intense cellular proliferation in the DMBA-treated animals, whereas no such features were observed in the other groups. Nuclear factor κB, a nuclear transcription factor, and proliferating cell nuclear antigen, a cell proliferation antigen, were studied by immunoblotting and immunohistochemistry and their levels were markedly elevated in the DMBA group compared with the others. Oxidative stress parameters, as studied by the inducible nitric oxide synthase activity, and the levels of reactive oxygen and nitrogen species were found to be suppressed in the DMBA group. Furthermore, fluorescent staining of the isolated lung cells from bronchoalveolar lavage was performed to study apoptosis and alterations in the mitochondrial membrane potential, and the DMBA-induced lung cancer was found to be associated with high inner mitochondrial membrane potential and a suppressed level of apoptosis.
