Precise and reliable identification of CNV is still important to fully understand the effect of CNV on genetic diversity and background of complex diseases. SNP marker has been used frequently to detect CNVs, but the analysis of SNP chip data for identifying CNV has not been well established. We compared various normalization methods for CNV analysis and suggest optimal normalization procedure for reliable CNV call. Four normal Koreans and NA10851 HapMap male samples were genotyped using Affymetrix Genome-Wide Human SNP array 5.0. We evaluated the effect of median and quantile normalization to find the optimal normalization for CNV detection based on SNP array data. We also explored the effect of Robust Multichip Average (RMA) background correction for each normalization process. In total, the following 4 combinations of normalization were tried: 1) Median normalization without RMA background correction, 2) Quantile normalization without RMA background correction, 3) Median normalization with RMA background correction, and 4) Quantile ormalization with RMA background correction. CNV was called using SW-ARRAY algorithm. We applied 4 different combinations of normalization and compared the effect using intensity ratio profile, box plot, and MA plot. When we applied median and quantile normalizations without RMA background correction, both methods showed similar normalization effect and the final CNV calls were also similar in terms of number and size. In both median and quantile normalizations, RMA background correction resulted in widening the range of intensity ratio distribution, which may suggest that RMA background correction may help to detect more CNVs compared to no correction.

PURPOSE: Recently, orbital wall fracture is common injuries in the face. Facial CT is essential for the accurate diagnosis and appropriate treatment to reconstruct of the orbital wall. The objective of this study was to report the method for accurate measurement of area and shape of the bony defect in the blow-out fractures using facial CT in prior to surgery. METHODS: The authors experienced 46 cases of orbital wall fractures and examined for diplopia, sensory disturbance in the area of distribution of the infraorbital nerve, and enophthalmos in the preoperation and followed 1 months after surgery, from August 2007 to May 2008. Bony defect was predicted by measuring continuous defect size from 3mm interval facial CT. Copying from the defect model(template), we reconstructed orbital wall with resorbable sheet(Inion CPS(R), Inion Oy, Tampere, Finland). RESULTS: One months after surgery using this method, 26(100%) of the 26 patients improved in the diplopia and sensory disturbance in the area of distribution of the infraorbital nerve. Also 8(72.7%) of the 11 patients had enophthalmos took favorable turn. CONCLUSION: This accurate and time-saving method is practicable for determining the location, shape and size of the bony defect. Using this method, we can reconstruc

Human personal genome sequencing can be done with high efficiency by aligning a huge number of short reads derived from various next generation sequencing (NGS) technologies to the reference genome sequence. One of the major obstacles is the incompleteness of human reference genome. We tried to analyze the effect of hidden gene duplication on the NGS data using the known example of hydin gene. Hydin2 , a duplicated copy of hydin on chromosome 16q22, has been recently found to be localized to chromosome 1q21, and is not included in the current version of standard human genome reference. We found that all of eight personal genome data published so far do not contain hydin2, and there is large number of nsSNPs in hydin. The heterozygosity of those nsSNPs was significantly higher than expected. The sequence coverage depth in hydin gene was about two fold of average depth. We believe that these unique finding of hydin can be used as useful indicators to discover new hidden multiplication in human genome.

OBJECTIVES: The CLOX (an executive clock drawing task) consists of an unprompted task that is sensitive to executive function (CLOX1) and a copied version that is more dependent on visuoconstructive function (CLOX2). This study aimed to explore the effects of age, education, and gender on the performance of the CLOX and to provide normative information on the test in the Korean elderly. METHODS: We administered the CLOX to 608 community-dwelling healthy volunteers aged 60-90, excluding people with serious neurological, medical, and psychiatric disorders, including dementia. Multiple linear regression analysis was performed to assess the relative contributions of the demographic factors to the CLOX scores. RESULTS: Education had a considerable influence on performance of both CLOX1 and CLOX2. Age and gender also had significant effect on both. There were significant interactions between education and gender for both CLOX1 and CLOX2. We also found interactions between education and age on CLOX2. Based on these results, we created normative data for the CLOX, stratified by age (60-74 and 75-90 years), education (0-3, 4-9, and 10+ years), and gender. CONCLUSION: Our normative data, based on a large, healthy elderly population, provides accurate reference information on CLOX performance and should be very useful for proper interpretation of CLOX scores in the Korean elderly.

OBJECTIVE: To investigate the effect of brain-derived neurotrophic factor (BDNF) Val66Met polymorphism on the recovery after subcortical stroke, using the modified Rankin Scale (mRS). METHODS: Subcortical stroke patients with copies of BDNF Val66Met polymorphism (n=7) were compared to their controls (n=7) without a copy of BDNF Val66Met polymorphism after matching for initial severity, location and type of stroke. The mRS scores at 1 and 3 months after discharge from the neurorehabilitation unit were compared between the groups. RESULTS: A repeated measures ANOVA for mRS revealed significant interaction between time and group (F(2, 24) =37.2, p<0.001) and a significant effect of time (F(2, 24)=10.8, p<0.001), thereby reflecting significant differences between the Met allele (+) group and the Met allele (-) group. There was a significant difference in mRS scores at 3 months post-discharge between the two groups (p=0.01) although no difference was evident in mRS scores at 1 month post-discharge between the two groups. There were significant improvements between mRS scores on admission and mRS scores at 1 month post-discharge (p=0.02), and between mRS scores at 1 month post-discharge and mRS scores at 3 months post-discharge (p=0.004) in the Met allele (-) group. CONCLUSION: BDNF Val66Met polymorphism may be associated with worse functional outcome in Korean patients with subcortical stroke. Therefore, BDNF Val66Met polymorphism should be considered as an important prognostic factor for recovery and responses to rehabilitation therapies after stroke in Korean patients. There is a need for developing different rehabilitation strategies for the population with BDNF Val66Met polymorphism. Further studies assessing different outcomes for various functional domains of stroke recovery are needed to clarify the role of BDNF Val66Met polymorphism.

9.Characterization of a Replication Element in the Coat Protein ORF of Turnip Yellow Mosaic Virus.
Journal of Bacteriology and Virology 2012;42(1):49-55
Turnip yellow mosaic virus (TYMV) is a non-enveloped icosahedral virus that has a single 6.3 kb positive-strand RNA as a genome. Previously, it was observed that the recombinant construct TY-eGFP2, where an eGFP gene was inserted at the position downstream of the coat protein (CP) ORF of TYMV genome, barely replicated. The inhibition of replication was relieved by insertion of an additional copy of the 3' quarter of the CP ORF after the foreign sequence. In this study, we have examined if the 3' quarter of the CP ORF contains any replication elements. M-fold analysis predicted three stem-loop structures in this region. Analysis of the TY-eGFP2 constructs containing one or two of these stem-loop structures indicates that the secondary structure predicted in the region between nt-6139 and nt-6181, termed SL2, is essential for TYMV replication. The critical role of SL2 was confirmed by the observation that deletion of the 3' quarter of the CP ORF from the wild-type TYMV genome nearly abolished replication and that insertion of SL2 into the deletion mutant restored the replication. Mutations disrupting the stem of SL2 greatly reduced viral RNA replication, indicating that the secondary structure is essential for the enhancing activity.

We have discovered copy number variations (CNVs) in 3,578 Korean individuals with the Affymetrix Genome-Wide SNP array 5.0, and 4,003 copy number variation regions (CNVRs) were defined in a previous study. To explore the details of the variants easily in related studies, we built a database, cataloging the CNVs and related information. This system helps researchers browsing these variants with gene and structure variant annotations. Users can easily find specific regions with search options and verify them from system-integrated genome browsers with annotations.
