ABSTRACT
Introduction: Hepatopulmonary syndrome [HPS] is known as a chronicliver disease associated with severe pulmonary deoxygenation due tointrapulmonary vascular vasodilation. Although liver transplantationis accepted as a main treatment of HPS, identifying effective drugs forrecovery of HPS can be effective in postponing the transplantation anddecreasing the mortality rate of patients before the transplantation. In thisstudy we briefly reviewed the pathogenesis of HPS and also systematicallyreviewed the current pharmacological treatment of HPS
Method: Pubmed, Scopus, and Google scholar were searched for therelevant English language clinical and experimental articles about themedications used in the treatment of HPS
Results: A total of 38 articles were included in this study which mostlyresulted in decreasing NOS expression, NO production, endothelin-1activation, intrapulmonary angiogenesis and increasing oxygenation
Conclusion: Various drugs have been proposed in treatment of HPS butmore large controlled trial studies, is necessary to determine the exactefficacy of each drugs for HPS recovery
ABSTRACT
In the current study, we compared the h-indices of Web of Science [WOS], SCOPUS, and GS of the Iranian nuclear medicine scientists. Full time members of two major nuclear medicine research centers of Iran with more than 5 year of experience [Nuclear Medicine Research Center of Mashhad University of Medical Sciences, and Research Institute for Nuclear Medicine of Tehran University of Medical Sciences] were included for h-index evaluation. H-indices of SCOPUS, WOS and GS were retrieved using their specific websites. Correlations of h-indices with each other were evaluated using spearman correlation coefficient. Overall 11 researchers were included in the study. SCOPUS, WOS, and GS provided somehow different h-indices for each researcher. Spearman's correlation coefficients between different h-indices were high: 0.834, 0.817, 0.857 between SCOPUS and WOS, SCOPUS and GS, and GS and WOS respectively. Rankings of researchers according to different database however, were acceptably identical. H-indices provided by SCOPUS, Web of Science WOS, and Google Scholar [GS] for Iranian nuclear medicine researchers can be used interchangeably. However these h-indices can be different according to which database is used. Setting up "ReasercherID" in WOS and "User profile" in GS, as well as giving regular feedback to SCOPUS managers can increase the accuracy of h-indices calculation

Citation tracking is a bibliometrics method to analyze the scientific impact of journal articles which can be done through Scopus [SC], Google Scholar [GS], or ISI web of knowledge [WOS]. In the current study, we analyzed the citations to 2006-2012 articles of Iranian Journal of Nuclear Medicine [IJNM] in the SC and GS. We retrieved the relevant data from SC and GS official websites. The search was done on 10/2012. Total number of citations, their overlap and unique citations of SC and GS were evaluated in detail. SC and GS covered 100% and 99% of articles and identified 53 and 62 citations to IJNM articles respectively with the overlap of 44 citations. Original articles were the main types of cited articles followed by review articles. Despite considerable overlap between GS and SC, they provide important unique citations to IJNM articles. Due to differences between citation analysis information in each database, authors should consider all the indexing databases when evaluating the scientific impact of the individual journal. Editors should consider original and review articles to increase long term visibility and hopefully impact factor of IJNM in the future
