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

Краткое описание

The present study was designed to investigate the effects of a selective cycloogenase-2 (COX-2) inhibitor, etoricoxib, on the membrane-specific enzymes, lipid composition, and changes in fluidity parameters of rat colonic plasma membrane. Two doses of the drug were used, one within its therapeutic anti-inflammatory range as based on the ED 50 value in rats (Eto-1), while the other at 10 times higher dose relating to the toxicity studies (Eto-2), which have not been reported so far. The activity of the membrane alkaline phosphatase was found to be increased after treatment with both the doses of etoricoxib as compared to the control. The total lipid and the cholesterol content showed a decrease while an increase in ganglioside sialic acid content was noted. Phospholipid content and the cholesterol-phospholipid molar ratio showed no change in either of the treatment groups. Fluorescence polarization studies with diphenylhexatriene showed that membrane fluidity was least altered in the isolated brush border membrane from colon or in the lipo somes prepared from the membrane lipid extracts. Also, the translational diffusion studied with pyrene showed that the fluidity parameter was decreased as measured by the excimer formation. It is concluded that etoricoxib, a new generation COX-2 inhibitor (called the coxibs), appeared to be a safe nonsteroidal anti-inflammatory drug (NSAID) in the colonic membranes.
