A journal indexed by the Institute for Scientific Information for SCI-expanded and by the National Library of Medicine for Index Medicus/MEDLINE is important to be recognized internationally. The Korean Journal of Radiology has been indexed in the database of the SCI-expanded since 2001 and Medicus/MEDLINE since 2000. The criteria for journal evaluation and selection by the National Library of Medicine include quality of editorial work, production quality, and quality of content. Most of the candidate journals contain reasonably good quality in editorial work and production. Thus, we believe that the quality of content is the most important criteria for the journal selection. To maintain a good quality of content, selection of the manuscript containing originality and scientific merits is imperative in review process. Highly selected, small number of articles per issue would be a wise editorial policy for a journal to be indexed by the well-known database.

PURPOSE: Laparoscopic radical prostatectomy is an alternative to open prostatectomy in the surgical management of prostate cancer. The introduction of surgical robot to assist laparoscopic surgery served as a mechanical device to enhance the laparoscopic skills and improve surgical maneuverability with enhanced visual systems and the multi-axis articulating instruments. This review will introduce the evolution of surgical technique and current status of robotic-assisted laparoscopic prostatectomy. MATERIALS AND METHODS: A review of literatures is conducted with the homepage of Korean Urologic Association and PubMed, a search tool of the National Library of Medicine and the National Institutes of Health, including the MEDLINE database. RESULTS: After its approval by the United States FDA in 2000, the robotic technology has revolutionized the treatment of surgical management of prostate cancer. Robotic-assisted laparoscopic radical prostatectomy offers benefits of minimally invasive surgery with comparable oncological functional outcomes compared to standard surgical options. CONCLUSIONS: This technique is expected to evolve into one of the standard of care in treatment of localized prostate cancer.

BACKGROUND: We reviewed the biological and mechanical properties of porous hydroxyapatite (HA) compared to other synthetic materials. Computer-aided design/computer-aided manufacturing (CAD/CAM) was also evaluated to estimate its efficacy with clinical and radiological assessments. METHOD: A systematic search of the electronic literature database of the National Library of Medicine (PubMed-MEDLINE) was performed for articles published in English between January 1985 and September 2013. The inclusion criteria were (1) histological evaluation of the biocompatibility and osteoconductivity of porous HA in vivo and in vitro, (2) evaluation of the mechanical properties of HA in relation to its porosity, (3) comparison of the biological and mechanical properties between several biomaterials, and (4) clinical and radiological evaluation of the precision of CAD/CAM techniques. RESULTS: HA had excellent osteoconductivity and biocompatibility in vitro and in vivo compared to other biomaterials. HA grafts are suitable for milling and finishing, depending on the design. In computed tomography, porous HA is a more resorbable and more osteoconductive material than dense HA; however, its strength decreases exponentially with an increase in porosity. CONCLUSIONS: Mechanical tests showed that HA scaffolds with pore diameters ranging from 400 to 1200 mum had compressive moduli and strength within the range of the human craniofacial trabecular bone. In conclusion, using CAD/CAM techniques for preparing HA scaffolds may increase graft stability and reduce surgical operating time.

For about 20 years, vertebroplasty has been used to achieve relief from pain and improve function in eligible patients affected by vertebral fractures. The procedure is also performed in patients with tumours of the vertebral body. The aim of this study was to investigate, by means of a literature review, correlations between vertebroplasty and the need for rehabilitation after patients with tumour-related vertebral fractures were operated on. This review was based on literature from the US National Library of Medicine, National Institutes of Health (PubMed), using the following Medical Subject Headings (MeSH) terms: "vertebroplasty," "surgical procedures minimally invasive," "bone neoplasm," "spine," "postoperative care," "rehabilitation," and "exercise." In total, 14 citations were retrieved: potentially relevant studies were identified by searching titles and abstracts, and then the full text of the selected articles was reviewed. From this review, the postoperative course of vertebroplasty today does not strictly indicate the need for rehabilitation.

OBJECTIVES: This study aimed to examine the feasibility of social network analysis as a valuable research tool for indicating a change in research topics in health care and medicine. METHODS: Papers used in the analysis were collected from the PubMed database at the National Library of Medicine. After limiting the search to papers affiliated with the National Institutes of Health, 27,125 papers were selected for the analysis. From these papers, the top 100 non-duplicate and most studied Medical Subject Heading terms were extracted. NetMiner V.3 was used for analysis. Weighted degree centrality was applied to the analysis to compare the trends in the change of research topics. Changes in the core keywords were observed for the entire group and in three-year intervals. RESULTS: The core keyword with the highest centrality value was "Risk Factor," followed by "Molecular Sequence Data," "Neoplasms," "Signal Transduction," "Brain," and "Amino Acid Sequence." Core keywords varied between time intervals, changing from "Molecular Sequence Data" to "Risk Factors" over time. "Risk Factors" was added as a new keyword and its social network was expanded. The slope of the keywords also varied over time: "Molecular Sequence Data," with a high centrality value, had a decreasing slope at certain intervals, whereas "SNP," with a low centrality value, had an increasing slope at certain intervals. CONCLUSIONS: The social network analysis method is useful for tracking changes in research topics over time. Further research should be conducted to confirm the usefulness of this method in health care and medicine.

The aim of this study is to design a biological information retrieval and analysis system (BIRAS) based on the Internet. Using the specific network protocol, BIRAS system could send and receive information from the Entrez search and retrieval system maintained by National Center for Biotechnology Information (NCBI) in USA. The literatures, nucleotide sequence, protein sequences, and other resources according to the user-defined term could then be retrieved and sent to the user by pop up message or by E-mail informing automatically using BIRAS system. All the information retrieving and analyzing processes are done in real-time. As a robust system for intelligently and dynamically retrieving and analyzing on the user-defined information, it is believed that BIRAS would be extensively used to retrieve specific information from large amount of biological databases in now days. The program is available on request from the corresponding author.

Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation method that delivers 1–2 mA of current to the scalp. Several clinical studies have been conducted to confirm the therapeutic effect of major depressive disorder (MDD) patients with tDCS. Some studies have shown tDCS's antidepressant effect, while the others showed conflicting results in antidepressant effects. Our aim of this review is to understand the biological bases of tDCS's antidepressant effect and review the results of studies on tDCS's antidepressant effect. For the review and search process of MDD treatment using tDCS, the US National Library of Medicine search engine PubMed was used. In this review, we discuss the biological mechanism of tDCS's antidepressant effect and the existing published literature including meta-analysis, systematic review, control trial, open studies, and case reports of antidepressant effects and cognitive function improvement in patients with MDD are reviewed. We also discuss the appropriate tDCS protocol for MDD patients, factors predictive of response to tDCS treatment, the disadvantages of tDCS in MDD treatment, and side effects.

OBJECTIVE: Physical or mental imbalance caused by harmful stimuli can induce stress to maintain homeostasis. During chronic stress, the sympathetic nervous system is hyperactivated, causing physical, psychological, and behavioral abnormalities. At present, there is no accepted standard for stress evaluation. This review aimed to survey studies providing a rationale for selecting heart rate variability (HRV) as a psychological stress indicator. METHODS: Term searches in the Web of Science®, National Library of Medicine (PubMed), and Google Scholar databases yielded 37 publications meeting our criteria. The inclusion criteria were involvement of human participants, HRV as an objective psychological stress measure, and measured HRV reactivity. RESULTS: In most studies, HRV variables changed in response to stress induced by various methods. The most frequently reported factor associated with variation in HRV variables was low parasympathetic activity, which is characterized by a decrease in the high-frequency band and an increase in the low-frequency band. Neuroimaging studies suggested that HRV may be linked to cortical regions (e.g., the ventromedial prefrontal cortex) that are involved in stressful situation appraisal. CONCLUSION: In conclusion, the current neurobiological evidence suggests that HRV is impacted by stress and supports its use for the objective assessment of psychological health and stress.
