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: 0.4 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: 0.1 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: 0.00005 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: 0.07 SJR: 0.198 SNIP: 0.48 CiteScore™:: 1.1 H-Index: 20

ABSTRAKT

An atmospheric pressure, room temperature (18-25 °C) gas discharge process has been investigated for its ability to elicit protein covalent cross-linking leading to oligomers. A practical application of such technique is to improve the stability of heat sensitive proteins of medical interest. A non-thermal plasma can be produced in transient filamentary discharge channels taking place in an atmospheric pressure dielectric barrier discharge reactor. The proteins are submitted to the discharge reactor effluents in an aqueous solution, consisting of lysozyme (14 kD) aqueous solutions (25 mg/ml). The protein solution is split up into 10 μl droplets deposited on a target surface in order to increase the gas/liquid exchange surface. After the plasma treatment, the proteins cross-linking reaction was ascertained by the visualization of protein bands on SDS-polyacrylamide gels corresponding to dimers (28 kD) and trimers (42 kD) of lysozyme. The intermolecular bonds were found to be covalent since the same migration bands were obtained in drastic denaturing conditions (disrupting hydrogen and Van der Waals intermolecular bonds). Under specific operating conditions, approximately 20 % of the total protein present is converted into dimers and trimers after only 5 minutes treatment. The influence, on the cross-linking efficiency, of different parameters (feed gas composition, exposure duration and solution composition) is discussed in the paper. First results suggest a possible biological activity of the cross-linked dimers.
