A correct alignment is an essential requirement in homology modeling. Yet in order to bridge the structural gap between template and target, which may not only involve loop rearrangements, but also shifts of secondary structure elements and repacking of core residues, high-resolution refinement methods with full atomic details are needed. Here, we describe(More)
A group key agreement protocol is designed to efficiently implement secure multicast channels for a group of parties communicating over an untrusted, open network by allowing them to agree on a common secret key. In the past decade many problems related to group key agreement have been tackled and solved (diminished if not solved), and recently some(More)
The Xpert MTB/RIF assay was introduced for timely and accurate detection of tuberculosis (TB). The aim of this study was to determine the diagnostic accuracy and turnaround time (TAT) of Xpert MTB/RIF assay in clinical practice in South Korea. We retrospectively reviewed the medical records of patients in whom Xpert MTB/RIF assay using sputum were(More)
This paper details the assessment process and evaluation results for the Critical Assessment of Protein Structure Prediction (CASP7) domain prediction category. Domain predictions were assessed using the Normalized Domain Overlap score introduced in CASP6 and the accuracy of prediction of domain break points. The results of the analysis clearly demonstrate(More)
Occasionally acute respiratory failure (ARF) develops in patients with connective tissue disease (CTD), but the etiologies of ARF in these patients are not fully elucidated. The objective of this study is to find out the causes of ARF leading to intensive care unit (ICU) admission in these patients and to assess their clinical outcome. The medical records(More)
Although combined pulmonary fibrosis and emphysema (CPFE) might be relevant to lung cancer, no comparison studies have been done. We evaluated the risk of lung cancer among CPFE patients compared to IPF and emphysema patients. We retrospectively reviewed the medical records of patients who were diagnosed as CPFE, IPF and emphysema using chest CT scans at(More)
We have investigated the effect of rigorous optimization of the MODELLER energy function for possible improvement in protein all-atom chain-building. For this we applied the global optimization method called conformational space annealing (CSA) to the standard MODELLER procedure to achieve better energy optimization than what MODELLER provides. The method,(More)
INTRODUCTION The impact of chronic obstructive pulmonary disease (COPD) on the mortality of patients with lung cancer has not been studied extensively. The objective of this study is to compare the mortality and clinical characteristics of patients with non-small-cell lung cancer (NSCLC) according to the presence of COPD. METHODS The medical records of(More)
OBJECTIVES The incidence of Pneumocystis jirovecii pneumonia (PCP) in patients without HIV infection (non-HIV PCP) has been increasing along with the increased use of chemotherapeutic agents and immunosuppressants, but the prognostic factors of non-HIV PCP remain unclear. This study aimed to identify the prognostic factors of non-HIV PCP. METHODS(More)
PURPOSE This study aimed to investigate whether the prevalence of postoperative pulmonary complications (PPCs) in patients with non-small-cell lung cancer (NSCLC) is even higher in the early stages of COPD than in such patients with normal lung function and to verify the usefulness of symptom- or quality of life (QoL)-based scores in predicting risk for(More)
