Although the enclosed rate of death certificates has steadily improved when domestic death notification to the government, the percent of well-certified causes of death is still 29th among the 35 Organization for Economic Cooperation and Development countries. The death certificate is a medical diagnosis how the deceased died, however, it is difficult to identify the causes of death such as cardiopulmonary arrest, unknown, and death due to old age were up to about 11%. The Statistics Korea selects the final cause of death by linking administrative records such as national health insurance records and national cancer registry data. The World Health Organization's the international statistical classification of diseases and related health problems, 10th revision, volume 2 manual, provides standard forms of death certificate and guidelines for how to write death certificates. It is necessary to provide the education materials or programs to the clinical doctors such as how differentiate the concepts of the underlying cause of death which is the basis of the death cause statistics, originating antecedent cause, main condition and the direct diagnosis of the death. Statistics on the causes of death are continuously needed to improve for the people's perception of death and to upgrade the quality of health care research and policy development.

This study aimed to analyze changing trends in child injury deaths from 2006 to 2016 and to provide basic data for initiatives to help prevent child injury deaths through improvements in social systems and education. Specific causes of death were analyzed using micro-data of the death statistics of Korea from 2006 to 2016, which were made available by Statistics Korea. Types and place of death were classified according to the KCD-7 (Korean Standard Classification of Diseases and Causes of Death). The data were compared to those of other Organization for Economic Cooperation and Development countries. Changing trends were presented. The number of child deaths by injury was 270 in 2016. The death rate was 8.1 per 100,000 population in 2006, while it was 3.9 in 2016. The death rate of boys was 1.7 times greater than that of girls. Unintentional injury deaths comprised 72.6% of all child injury deaths in 2016, while intentional injury deaths comprised 27.4%. The first leading cause of unintentional injury deaths in infants (less than 1-year-old) was suffocation, while that of children aged 1 to 14 years was transport accidents. The second leading cause of death in infants was transport accidents, that of children aged 1 to 4 was falling, and that of children aged 5 to 14 was drowning. Pedestrian accidents comprised 43.7% of the transport accidents from 2014 to 2016. To prevent child injury deaths by both unintentional and intentional causes, nation-wide policy measures and more specific interventions according to cause are required.

MicroRNAs play an important role in regulating gene expression, but their target identification is a difficult task due to their short length and imperfect complementarity. Burge and coworkers developed a program called TargetScan that allowed imperfect complementarity and established a procedure favoring targets with multiple binding sites conserved in multiple organisms. We improved their algorithm in two major aspects - (i) using well-defined UTR (untranslated region) database, (ii) examining the extent of conservation inside the 3' UTR specifically. Average length in our UTR database, based on the ECgene annotation, is more than twice longer than the Ensembl. Then, TargetScan was used to identify putative binding sites. The extent of conservation varies significantly inside the 3' UTR. We used the "tight" tracks in the UCSC genome browser to select the conserved binding sites in multiple species. By combining the longer 3' UTR data, TargetScan, and tightly conserved blocks of genomic DNA, we identified 107 putative target genes with multiple binding sites conserved in multiple species, of which 85 putative targets are novel.

BACKGROUND AND OBJECTIVES: Thrombin and its interaction with platelets play a pivotal role in arterial thrombus formation. Hirudin, an anticoagulant agent derived from medicinal leeches(Hirudo medicinalis), is a unique and specific thrombin inhibitor with no effect on other serine protease. We investigated the inhibitory effect of hirudin on platelet deposition in a rabbit carotid artery eversion model of acute arterial thrombosis. MATERIALS AND METHODS: The everted arterial segments were perfused with 111 Indium-labeled human platelets only(control, n=8), and a mixed solution of 111 Indium-labeled human platelets and hirudin(30, 45, 60, 90 microgram/ml, n=3, respectively). Platelet deposition was calculated by a gamma-counter and confirmed by scanning electron microscopy. RESULTS: 1) Indium-111 labeling efficiency of platelets was 87.0+/-6.6%, and the aggregation of platelets was not changed after labeling. The number of platelets perfused through each arterial segment was 4.3 +/-0.2x10(8) platelets/ml. 2) The control group showed a platelet deposition rate of 23.9+/-7.0 % and a number of platelet deposition of 9.8+/-2.5x10(8) platelets/cm2 . 3) Platelet deposition of arteries perfused with hirudin(60 microgram/ml) was significantly decreased compared with that of the control group(2.9+/-0.6 vs 9.8+/-2.5x10(8)/cm2 , p<0.05). 4) The number of deposited platelets in hirudin-perfused arteries was dose-dependently decreased(30 microgram/ml:6.7+/-1.4x10(8) /cm2 , 45 microgram/ml: 4.8+/-1.7x10(8) /cm2 , 60 microgram/ml: 2.9+/-1.8x10(8)/cm2, 90 microgram/ml:2.9+/-1.4x10(8)/cm2: p<0.05 vs. control, respectively). 5) Scanning electron microscopic examination revealed significantly reduced platelet deposition in hirudin-perfused groups compared with control group. CONCLUSION: Hirudin inhibits effectively platelet deposition and arterial thrombus formation in a rabbit carotid artery eversion model. The antiplatelet effect of hirudin in this model suggests that hirudin may be an useful antithrombotic agent therapeutically useful in the prevention of acute arterial thrombus formation.

Fusion proteins resulting from chimeric sequences are excellent targets for therapeutic drug development. We developed a database of chimeric sequences by examining the genomic alignment of mRNA and EST sequences in the GenBank. We identified 688 chimeric mRNA and 20,998 chimeric EST sequences. Including EST sequences greatly expands the scope of chimeric sequences even though it inevitably accompanies many artifacts. Chimeric sequences are clustered according to the ECgene ID so that the user can easily find chimeric sequences related to a specific gene. Alignments of chimeric sequences are displayed as custom tracks in the UCSC genome browser. ChimerDB, available at http://genome.ewha.ac.kr/ECgene/ChimerDB/, should be a valuable resource for finding drug targets to treat cancers.

This study aimed to analyze infant, maternal, perinatal, and fetal mortality statistics in the Republic of Korea (Korea), 2014. It was based on the open-access data available from the Statistics Korea website (http://kostat.go.kr/portal/eng/index.action). Recent trends in these vital statistics were also examined. The results of this study constitute a descriptive presentation and analysis of the national data. The number of infant deaths was 1,305 out of 435,435 live births in 2014, and the infant mortality rate was 3.0. The number of maternal deaths was 48. The maternal mortality ratio per 100,000 live births was 11.0. The maternal mortality ratio per 100,000 women of child-bearing age (15 to 49 years old) was 0.37. The number of perinatal deaths was 1,365, and the perinatal mortality rate was 3.1. The number of fetal deaths was 5,317. The fetal mortality rate was 12.1. The trends in those vital statistics in recent years were consistent except for a few findings, including a decrease in the maternal mortality ratio of pregnant women 40 years old and older and a change in the proportions of the causes of infant death, with a decrease in mortality due to neonatal respiratory distress and an increase in mortality due to bacterial sepsis. Although these vital statistics were generally consistent, some aspects varied by year. Pregnant women less than 20 years old should be monitored more intensively for their babies' health. Our findings can serve as basic data supporting the establishment of health policies by the Korean government.

This article presents recent trends and statistical indicators related to mortality in the Republic of Korea by analyzing the 2014 cause-of-death statistics. Specifically, we assessed the number of deaths, the crude death rate, the ranking of causes of death, and trends in the death rate from the major causes of death. Causes of death were classified according to the International Statistical Classification of Diseases and Related Health Problems, 10th revision, as recommended by the World Health Organization. In order to determine the ranking of causes of death, Statistics Korea used the selection list of 56 causes of death from the 80 causes of death list for tabulation mortality statistics recommended by World Health Organization to better fit the Korean situation. The 10 leading causes of death were, in order, cancer, heart disease, cerebrovascular disease, suicide, pneumonia, diabetes mellitus, chronic lower respiratory disease, liver disease, transport accidents, and hypertensive diseases. The top 10 causes of death accounted for 70.5% of all Korean deaths. The ranking of cancer types as causes of death was lung, liver, stomach, colon, and pancreatic cancer. Death rates for heart disease increased from the third in 2013 to the second leading cause in 2014 and the rank of pneumonia moved up from the sixth in 2013 to the fifth in 2014. The mortality rate due to stomach cancer has decreased continuously over time.. This finding may reflect changes in Korean society involving population structure, epidemiological patterns, and lifestyles, including dietary habits.

The external elastic lamina (EEL) serves as a barrier for cells and macromolecules between the media and adventitia in the vascular wall. We evaluated the morphological changes and quantitative assessments of the EEL architecture in the coronary circulation of pigs fed with a high cholesterol diet. Confocal microscopy analysis of the EEL from hypercholesterolemic coronary arteries revealed an altered pattern characterized by fragmentation and disorganization of the EEL associated with an increase in the thickness. Computerized digital analysis of the images obtained by confocal scanning microscopy demonstrated that compared to normal coronary arteries, the EEL of hypercholesterolemic coronary arteries decreased in the percentage of their elastin content (30.80 +/- 1.64% vs. 47.85 +/- 1.82%, p = 0.001). The percentage of elastin content was negatively correlated with the vessel wall area (r = -0.82, p = 0.001). The immunoreactivity for matrix metalloproteinase-3 (MMP-3) increased in cholesterol-fed coronary arteries, predominantly in the neointima and adventitia. This study demonstrates that experimental hypercholesterolemia induced ultrastructural changes of the EEL in coronary circulation. The EEL may also be an atherosclerosis-prone area compared with the intima. The EEL may play an important role in the development of structural changes which characterizes the early phase of coronary atherosclerosis and vascular remodeling.

This study aimed to analyze changes in the causes of death in the Korean population in 2016 and to provide some insights regarding how to cope with related issues of public health and welfare. The causes of death made available by Statistics Korea were classified according to the International Statistical Classification of Diseases and Related Health Problems, 10th revision as well as the KCD-7 (Korean Standard Classification of Diseases and Causes of Death), which has been modified to fit circumstances in Korea. The total number of deaths was 280,827, which was an increase of 4,932 (1.8%) from 2015. The crude death rate was 549.4 per 100,000 population, which was an increase of 7.9 (1.5%) from 2015. The 10 leading causes of death, in order, were malignant neoplasms, heart diseases, cerebrovascular diseases, pneumonia, intentional self-harm, diabetes mellitus, chronic lower respiratory diseases, liver diseases, hypertensive diseases, and transport accidents. The rank of hypertensive diseases rose from 10th in 2015 to 9th in 2016, while that of transfer accidents dropped from 9th in 2015 to 10th in 2016. The proportion of the number of deaths caused by cancer was 27.8%. The death rate due to cancer was 153.0 per 100,000 population, which was an increase of 1.4% from 2015; 16.5 deaths per 100,000 population were due to colon cancer, and 16.2 were due to stomach cancer. The above trends in causes of death reflect aspects of the population structure, disease patterns, lifestyle, and medical care in present-day Korean society.
