Background: This study was conducted to analyze the current problems in completing death certificates and to identify the correct method for completing death certificates Methods: We reviewed 262 death certificates in three hospitals from March 1 to April 30, 2000, and 119 death certificates in one hospital from March 1 to 31, 2000. We identified major and minor errors and analyzed and compared them retrospectively. Results: A total of 381 death certificates were reviewed: 59 in Seoul National University Hospital,101 in Ewha Woman's University Hospital, and 102 in Gachon Medical College Hospital, which has no education program for completing death certificates in postgraduate training, and 119 in Samsung Medical Center which has an education program for completing death certificates. 358 certificates(94.0%) had at least one error. There were only 23 death certificates(6.0%) without an error. In 182 cases(47.8%), there was one major error. In 321 death certificates(84.3%), there were more than two errors. A comparison of Samsung Medical Center with the other hospitals showed that the number of total errors was statistically different(p=0.001). Conclusion: There were few death certificates without an error in this study. In a hospital which has postgraduate training in completing death certificates, there are fewer errors than in other hospitals which have no training course. Emergency physicians actually certify many deaths, so they must know the correct method of completing death certificates for statistics on morbidity and mortality.

The effect of high molecular weight (HMW, 200,000-300,000) chitosan on neonatal streptozotocin (STZ)-induced noninsulin-dependent diabetes mellitus ICR mice was investigated by analyzing body weight, food and water consumption, urine volume, non-fasting serum glucose, urine glucose, serum triglyceride, and cholesterol levels. HMW chitosan (0.2% or 0.8%) was given to the mice as drinking water for 8 weeks, and daily administration reduced body weight, water consumption, urine volume, serum triglyceride and cholesterol levels; however, HMW chitosan had no effect on blood and urine glucose levels in these mice.
SIDR: simultaneous isolation and parallel sequencing of genomic DNA and total RNA from single cells
Han, Kyung Yeon,Kim, Kyu-Tae,Joung, Je-Gun,Son, Dae-Soon,Kim, Yeon Jeong,Jo, Areum,Jeon, Hyo-Jeong,Moon, Hui-Sung,Yoo, Chang Eun,Chung, Woosung,Eum, Hye Hyeon,Kim, Sangmin,Kim, Hong Kwan,Lee, Jeong Eo Cold Spring Harbor Laboratory Press 2018 Genome research Vol.28 No.1
<P>Simultaneous sequencing of the genome and transcriptome at the single-cell level is a powerful tool for characterizing genomic and transcriptomic variation and revealing correlative relationships. However, it remains technically challenging to analyze both the genome and transcriptome in the same cell. Here, we report a novel method for simultaneous isolation of genomic DNA and total RNA(SIDR) from single cells, achieving high recovery rates with minimal cross-contamination, as is crucial for accurate description and integration of the single-cell genome and transcriptome. For reliable and efficient separation of genomic DNA and total RNA from single cells, the method uses hypotonic lysis to preserve nuclear lamina integrity and subsequently captures the cell lysate using antibody-conjugated magnetic microbeads. Evaluating the performance of this method using real-time PCR demonstrated that it efficiently recovered genomic DNA and total RNA. Thorough data quality assessments showed that DNA and RNA simultaneously fractionated by the SIDR method were suitable for genome and transcriptome sequencing analysis at the single-cell level. The integration of single-cell genome and transcriptome sequencing by SIDR (SIDR-seq) showed that genetic alterations, such as copy-number and single-nucleotide variations, were more accurately captured by single-cell SIDR-seq compared with conventional single-cell RNA-seq, although copy-number variations positively correlated with the corresponding gene expression levels. These results suggest that SIDR-seq is potentially a powerful tool to reveal genetic heterogeneity and phenotypic information inferred from gene expression patterns at the single-cell level.</P>

Background: In recent years, there has been increasing interest in the use of capnometry, the noninvasive, continuous measurement of end-tidal carbon dioxide(ETCO2) in expired air during CPR. The purpose of this study is to determine the significance of ETCO2 monitoring according to immediate cause of arrest during CPR as a prognostic indicator of successful resuscitation and survival. Methods: A prospective, clinical study was performed from May 1997 to December 2000 at the Department of Emergency Medicine, Ewha Womans University Mokdong Hospital. The study included 220 patients(231cases). All patients were immediately connected to a mainstream capnometer sensor between the tube and the bag after endotracheal intubation using an infrared capnometer. Results: The 107 patients(46.3%) with return of spontaneous circulation(ROSC) had higher maximal ETCO2 during CPR than the 113 patients without ROSC(31.0±19.4 vs 11.7±9.4 mmHg, P=0.000). The ETCO2 was not significantly different in relation to age, initial rhythm, and survival time after ROSC, but there was a significant difference in the immediate cause of arrest in the ROSC group(respiratory arrest: 40.2±23.5 mmHg, P=0.000). In case of cardiac arrest due to trauma, maximal ETCO2 was not significant in the ROSC group compared with the non-ROSC group(18.2±16.6 vs 10.8±7.5 mmHg, P=0.208). When maximal ETCO2 was less than 10 mmHg, we observed a sensitivity of 94.4% and a specificity of 39.5% in predicting ROSC. There were 6 patients with ROSC even though the maximal ETCO2 was less than 10 mmHg. Conclusion: Continuous ETCO2 monitoring during CPR may be noninvasive and valuable predictor of successful resuscitation and survival from cardiac arrest. However, ETCO2 should not be used as a single indicator for either cardiac arrest due to trauma or withdrawal of CPR.

Kim, Yeon-Sik,Choi, Ki-Yong,Kang, Kyoung-Ho,Park, Hyun-Sik,Cho, Seok,Baek, Won-Pil,Kim, Kyung-Doo,Sim, Suk-K.,Lee, Eo-Hwak,Kim, Se-Yun,Kim, Joo-Sung,Choi, Tong-Soo,Kim, Cheol-Woo,Lee, Suk-Ho,Lee, Sang Korean Nuclear Society 2011 Nuclear Engineering and Technology Vol.43 No.1
KAERI has been operating an integral effect test facility, ATLAS (Advanced Thermal-Hydraulic Test Loop for Accident Simulation), for accident simulations of advanced PWRs. Regarding integral effect tests, a database for major design basis accidents has been accumulated and a Domestic Standard Problem (DSP) exercise using the ATLAS has been proposed and successfully performed. The ATLAS DSP aims at the effective utilization of an integral effect database obtained from the ATLAS, the establishment of a cooperative framework in the domestic nuclear industry, better understanding of thermal hydraulic phenomena, and an investigation of the potential limitations of the existing best-estimate safety analysis codes. For the first ATLAS DSP exercise (DSP-01), integral effect test data for a 100% DVI line break accident of the APR1400 was selected by considering its technical importance and by incorporating comments from participants. Twelve domestic organizations joined in this DSP-01 exercise. Finally, ten of these organizations submitted their calculation results. This ATLAS DSP-01 exercise progressed as an open calculation; the integral effect test data was delivered to the participants prior to the code calculations. The MARS-KS was favored by most participants but the RELAP5/MOD3.3 code was also used by a few participants. This paper presents all the information of the DSP-01 exercise as well as the comparison results between the calculations and the test data. Lessons learned from the first DSP-01 are presented and recommendations for code users as well as for developers are suggested.

Blastocystis is a genus of unicellular heterokont parasites belonging to a group of organisms known as Stramenopiles, which includes algae, diatoms, and water molds. Blastocystis includes several species that habitat in the gastrointestinal tracts of organisms as diverse as humans, farm animals, birds, rodents, reptiles, amphibians, fish, and cockroaches. It is important to public health and distributed globally, but its prevalence in dogs in Korea has not been reported to date. Here, we collected 787 canine fecal samples and assessed Blastocystis infection by age, sex, region, season, and diarrhea symptoms. We determined Blastocystis subtypes using phylogenetic analyses based on 18S rRNA gene sequences. We identified, 10 Blastocystis positive samples (1.3%). A higher proportion of infected dogs was asymptomatic; however, infection rates did not significantly differ according to region, age, sex, and season. Phylogenetic analysis showed that the Blastocystis sp. identified belonged to 4 subtypes (STs), ST1, ST5, ST10, and ST14, thus revealed the genetic diversity of Blastocystis sp. in dogs Korean. This is first report on the presence of Blastocystis sp. in dogs Korean. This study revealed a lower infection rate than expected and differed from previous studies in STs. Further studies are warranted to observe the national infection status of Blastocystis in dogs and the genetic characteristics of this genus.
