CORMACK ALLAN (1924-1998) Allan MacLeod Cormack (February 23, 1924 – May 7, 1998) was born in Johannesburg, South Africa, the son of George and Amelia, a civil service engineer and a teacher respectively, who had emigrated from Scotland to South Africa prior to World War I (1). At the University of Cape Town, South Africa, Cormack chose the field of engineering, but two years later he changed his major to physics, completing a baccalaureate of science in 1944. He remained at the University of Cape Town, completing a Master of Science degree in the field of crystallography in 1945. During the years that followed,Cormack became a lecturer in physics at the University of Cape Town and pursued graduate studies in the field of theoretical physics for two years at Cambridge University in England. In 1950 Cormack returned to South Africa from Cambridge and during this period he was asked to serve a sixmonth service as resident medical physicist in the radiology department in Cape Town, where he supervised the use of radioisotopes as well as the calibration of film badges used to measure hospital workers’ exposure to radiation. At Groote Schuur, Cormack witnessed first hand how radiation was being used in the diagnosis and treatment of cancer patients. Baffled by deficiencies in the technology used for such procedures, Cormack began a series of experiments and analyses, the results of which were two papers published separately between 1963 and 1964 in the Journal of Applied Physics . Between 1956 and 1964, most of his research in connection with the development of computerized axial tomography was conducted on his own time. Neither of his two Journal of Applied Physics papers met with significant response, despite the fact that they proved the feasibility of his method for producing images of heretofore non visible or barely visible cross sections of the human body. Hounsfield was independently coming to conclusions similar to Cormack’s, and developed the first CAT scanner as early as 1972. In 1979 Cormack and Hounsfield were awarded the Nobel Prize for physiology or medicine for their joint, though independent, development of CAT scan theory and technology. Unlike previous Nobel recipients, neither Cormack nor Hounsfield held a doctorate in medicine or science; further, their discovery was awarded the prize only after the Nobel Assembly voted the first choice of the selection committee; and, finally, it was highly unusual that the two men had never met or worked together, yet had worked on the same invention concurrently. In 1990, as one of several scientists receiving the National Medal of Science, Cormack was recognized by President George Bush. Cormack is a member of the National Academy of Science and the American Academy of Arts and Sciences, and is a fellow of the American Physical Society. Cormack died of cancer in Massachusetts at age 74. He was posthumously awarded the Order of Mapungubwe for outstanding achievements as a scientist and for co-inventing the CT scanner.

“Medical Archives” was founded in 1947 as a professional journal of the “AssSociation of Physicians of Bosnia and Herzegovina”. First Editorial Board consists of academicians: Vladimir Cavka, Editor-in-Chief, Blagoje Kovacevic, Bogdan Zimonjic and Ibro Brkic, members of the Editorial Board. Till today in Editorial Boards of Medical Archives were included over 300 medical doctors from almost every medical disciplines and from all parts of Bosnia and Herzegovina, and also from abroad (1). During past was continuously has published 68 volumes of the journal, in average 4-6 issues per one volume. Last ten years journal is published bi-monthly. Till now in Medical Archives was published over 5000 articles. Most of them were original papers from all medical disciplines. “Medical Archives” is now indexed in the following databases: PubMed/MedLine (from 1972, abstracted in this bases more than 5.500 journals), PubMed Central (from 2013), and from the year 2009 in databases: Excerpta Medica/EMBASE, Scopus, Scirus, EBSCO, DOAJ, Index Copernicus, Ulrich’s Periodicals Directory, Geneva Foundation for Medical Education and Research–GFMER, HINARI, ProQuest, NewJour, SCImago Journal & Country Rank, ISC Master List Journals, CrossRef, Google Scholar, Genamics JournalSeek, WorldCat, VINITI of RAS, Research Gate, Catalyst, ScopeMed, SafetyLit, BioinfoBank Library, PubGet, GetCited, CIRRIE, Kubon and Sagner OPAC. H index of the “Medical Archives” is 11 for 2013 (www.scimagojr.com), which represents the largest citation index journals of one journal in the biomedical field on the territory of Bosnia and Herzegovina (2), and since 2013, with full-text articles at PubMed Central (Figure 1) (the most prominent database of biomedical literature, which contains more than 4.5 million articles). Figure 1 “Medical Archives” in PubMed Central database During calendar year 2014 in Medical Archives was published 110 articles in 6 issues (3). The largest number of articles was original articles. Small number has been published as professional and review articles, and case reports. Each issue contained the texts such as: news, book reviews, in memoriam and guidelines (both professional and educational). In the journal “Medical Archives” number of articles published during last three years is approximately the same (Figure 2), between 100 and 120, but with statistically significant variations in article types (χ2=15.332). Figure 2 “Medical Archives” in the period 2012-2014 In the journal “Medical Archives” during the last three years were most common articles in the field of clinical medicine. There has been an upward trend in the number of articles in the field of preclinical medicine (Figure 3) but without significant difference in the observed period (χ2=7.761; p=0.185). Figure 3 Field in which are published articles in the journal “Medical Archives” in the period 2012-2014 From the clinical medical field over the past three years, in the journal “Medical Archives” were usually presented articles of general internal and surgical disciplines (Figure 4). There has been an increase in the number Article in the field of family medicine and dermatovenerology, but without statistically significant difference (χ2=27.847; p=0.064). Figure 4 Representation of clinical disciplines in the journal “Medical Archives” in the period 2012-2014 Preclinical medicine in the journal “Medical Archives” was most often represented by the articles in the field of pharmacology and biochemistry. In 2014, in the journal were present also articles in the field of medical informatics (Figure 5) but without significant differences between observed years (χ2=11.35; p=0.182). Figure 5 Representation of preclinical disciplines in the journal “Medical Archives” in the period 2012-2014 By exploring and analyzing the selected theme, the author of this Editorial came to the following conclusions (3, 4): The number of articles published each year is increasing, with a larger number of authors from many countries and four continents (usually Europe); Rejecting rate is more than 40 %; There is a trend to join forces in terms of regional cooperation when writing articles; The most common are the original articles; The areas of clinical medicine are still the most common in journals (number of articles in the field of radiology, gynecology and ophthalmology are increasing); Preclinical disciplines were most often represented within the articles in the field of medical informatics; Most reviewers of articles are from Bosnia and Herzegovina, but there is also a considerable number from abroad (from more than 20 countries); The most common period which is necessary for the review was between fifty and fifty nine days; Most authors are from the territory of Bosnia and Herzegovina (more than 50 %) During 2014 we discovered only 3 cases of Plagiarism (one case from Bosnia and Herzegovina and two from Egypt) (3).

Anomalous couplings of the Z boson to top quarks are only marginally constrained by direct searches and are still sensitive to new particle dynamics at the TeV scale. Employing an effective field theory approach we consider the dimension-six operators which generate deviations from the standard-model vector and axial-vector interactions. We show that rare B and K meson decays together with electroweak precision observables provide strong constraints on these couplings. We also consider constraints from t-channel single-top production.

Introduction: This study evaluated the frequency of domination of the coronary arteries types in patients treated by surgical myocardial revascularization. The aim of the study was to determine whether the left coronary circulation dominance is a prognostic factor for poorer outcome in patients undergoing coronary artery bypass surgery. Material and methods: A total sample consisted of 100 patients with coronary artery disease that were treated with coronary artery bypass grafting at the Clinic for Cardiac Surgery, Clinical Center of the University of Sarajevo. To all patients on the basis of preoperative coronary angiography was determined the dominance of the coronary arteries. Patients included in the study were divided into two groups, with the left and right with coronary dominance. Results: Left coronary dominance in a sample of patients was present in 21/100 (21%), right in 69/100 (69%) and balanced in 10/100 (10%) cases. Female gender was significantly more frequent in patients with left coronary dominance and proved to be a stronger predictor of poorer outcome, especially in combination with left main stenosis of the left coronary artery and left coronary dominance. Inability of revascularization of the r. interventricularis posterior (RIVP) was statistically significantly higher in case of left dominance 9/21 (42.9%), compared to the right 16/79 (20.3%), p=0.033. Lethal outcome was more common in case of left dominance in relation to the right (9.4% vs 0.9%). The incidence of surgical complications, respiratory, neurological and renal complications was not significantly different between groups, while the length of hospital stay was significantly higher in the group of patients with left dominance, p = 0.003. Conclusion: Left coronary dominance is an important risk factor for patients undergoing surgical myocardial revascularization.
