Background: Renal involvement in patients with idiopathic inflammatory myopathies (IIM) is previously thought to be uncommon. However, recent studies reported that renal involvement may occur in nearly 20% of IIM patients, and some possible risk factors are proposed. Objectives: We investigate the prevalence, risk factors, and prognosis of renal involvement in Korean patients with IIM. Methods: Clinical and laboratory data of 50 patients diagnosed with IIM in Seoul St. Mary's hospital between 2005 and 2015 were investigated through retrospective medical chart review. AKI was defined as an acute doubling of serum creatinine level, and CKD as GFR less than 60 ml/min/1.73m2 over 3 months. And other renal involvement such as proteinuria more than 300mg/day or microscopic hematuria was evaluated Results: Eight patients were found to have renal involvement. The prevalence of renal involvement in our study population was similar to previous studies conducted in other countries (16% vs. 20%, respectively). However, clinical manifestations were different; there were no patients with AKI at initial diagnosis and no one progressed to CKD. All eight patients showed proteinuria or hematuria. When the potential risk factors (age at IIM onset, sex, type of IIM, underlying disease, serum muscle enzyme levels, presence of interstitial lung disease (ILD)) for renal involvement were analyzed, high level of serum muscle enzymes at the diagnosis was associated with renal involvement (CPK 5389 [2088-9662] vs. 1222 [177-3789] U/L, p=0.009; LDH 2323 [1084-2665] vs. 861.50 [633-1306] U/L, p=0.020). Neither the presence of interstitial lung disease nor the presence of other comorbities was related to renal involvement. The prognosis of the renal involvement was good; proteinuria or hematuria in six patients was abrogated with the use of steroid/immune suppressive agents. There was only 1 patient who had persistent proteinuria until she expired due to uncontrolled IIM. Conclusions: Renal involvement in patients with IIM is not rare in Korea and is associated with initial high level of serum muscle enzymes. The possibility of renal involvement should be considered and closely monitored when treating IIM patients.

<P> The photoluminescence quantum yield (PLQY) and charge carrier mobility of organic?inorganic perovskite QDs were enhanced by the optimization of crystallinity and surface passivation as well as solid-state ligand exchange. The crystallinity of perovskite QDs was determined by the Effective solvent field (E<SUB>sol</SUB>) of various solvents for precipitation. The solvent with high E<SUB>sol</SUB> could more quickly countervail the localized field generated by the polar solvent, and it causes fast crystallization of the dissolved precursor, which results in poor crystallinity. The post-ligand adding process (PLAP) and post-ligand exchange process (PLEP) increase the PLQY of perovskite QDs by reducing non-radiative recombination and the density of surface defect states through surface passivation. Particularly, the post ligand exchange process (PLEP) in the solid-state improved the charge carrier mobility of perovskite QDs in addition to the PLQY enhancement. The ligand exchange with short alkyl chain length ligands could improve the packing density of perovskite QDs in films by reducing the inter-particle distance between perovskite QDs. The maximum hole mobility of 6.2 × 10<SUP>-3</SUP> cm<SUP>2</SUP> V<SUP>-1</SUP> s<SUP>-1</SUP>, one order higher than that of pristine QDs without the PLEP, is obtained at perovskite QDs with hexyl ligands. By using PLEP treatment, compared to the pristine device, a 2.5 times higher current efficiency in perovskite QD-LEDs was achieved due to the improved charge carrier mobility and PLQY. </P>

4개의 후보 유전자를 분석해본 결과, 돼지의 주요 염색체 부위 및 유전자들이 주요 경제성 요인들과 관계가 있는 것으로 확인됐다. 양돈업계에서 DNA 기술을 이용한 염색체 정보를 활용하기 위해 본 연구에서는 4개의 후보 유전자에서 생성된 중합효소연쇄반응(PCR) 생성물을 비교 재 서열 함으로써 단일염기변이(SNP) 표지들을 개발했다. 또한 이들 4개의 SNP에 대해 PCR 제한효소 절편길이 다형 성(RFLP) 분석을 전개한 후, 이를 대한민국내 버크셔 종 돼지 개체군의 유전자형을 분석하는데 활용했다. 본 연구는 유용한 단일염기변이를 식별하고 돼지개체군 내 경제적으로 중요한 특성들과 SNP의 연관성을 확인하는 데 그 목적이 있다. This study was conducted to identify useful single nucleotide polymorphisms (SNPs) and determine their association with economically important traits in pig population. Four candidate gene analyses have identified important chromosomal regions and major genes associcated whit economic traits of the pig. For application of the chromosomal information to the pig industry using DNA technology, SNP markers were developed by comparative re-sequencing of polymerase chain reaction (PCR) products of 4 candidate genes (CSF2, IL4, MYOD, RIP140). PCR restriction fragment length polymorphism (PCR-RFLP) assays were developed for these 4 SNPs and used to genotype Berkshire pig populations in Korea.

본 연구는 돼지 4번 염색체에서 FAT1 좌위의 후보유전자인 Adipocyte Fatty-Acid 결합단백질 (FABP4) 유전자에서 8개의 Single Nucleotide Polymorphisms (SNPs) 를 발견하였다. Duroc, Landrace, Berkshire, Yorkshire를 기초 축으로 이용한 800두에 대해 FABP4 유전자의 단일염기 분석과 PCR-RFLP를 이용하여 그 다형성을 조사하고 돼지의 일당증체량, 등지방두께, 사료요구율, 정육율과 그 유전자형 간의 연관성을 규명하고자 실시하였다. FABP4 유전자에 대해 각 단일염기에 관한 PCR-RFLP를 이용하여 400~800 bp 산물을 증폭한후 각각의 제한효소로 사용하여, 얻어진 FABP4 유전자의 빈도는 품종별로 다르게 나타났다. 통계적 분석을 통하여 각 유전자형에 대한 경제형질과 연관성을 분석한 결과 일당증체량, 등지방두께, 정육율, 사료요구량은 다른 유전자형을 가진 개체들이 유의적으로 우수한 능력을 보였다 (P<0.05). FABP4유전자는 일당증체량, 정육율, 등지방두께 에 높은 연관성이 있음을 관찰하였다. 따라서 돼지의 성장과 정육율에 관련된 선발력을 높이기 위해서 FABP4 유전자의 다형성 분석에서 검증된 PCR marker를 우량돼지육종 계획에 있어 분자생물학적 선발 marker로 사용할 수 있을 것으로 사료된다. We found 8 single nucleotide polymorphisms (SNPs) in adipocyte fatty acid bonding protein (FABP4) gene as candidate gene of FAT1 locus on pig chromosome 4. With over 800 heads of major commercial pig breeds including Duroc, Landrace, Berkshire and Yorkshire, we analyzed SNPs of FABP4 gene to determine possible effects of FABP4 genotype to economically important traits. 400~800 bp amplicons in FABP4 gene were used PCR-RFLP for each SNPs and we found that the frequency of some SNPs of this gene was different among the breeds. According to the statistical analyses to determine possible associations of each genotype with economic traits, it was found that subgroup with different genotypes showed significant differences in daily gain, backfat thickness, lean percentage and feed conversion ratio (P<0.05). Thus, as a part of enhancing the selection competence related to swine growth rate and lean percentage, it is expected that FABP4 gene markers verified in this study will be useful to use for Korean commercial pig industry.

BACKGROUND: Reuse of waste nutrient solution for the cultivation of crops could lead to considerable conservation of water resources, plant nutrients, and water quality. Therefore, this study was conducted to evaluate the potential for reducing the use of chemical fertilizer in Chinese cabbage cultivation via the reuse of waste nutrient solution as an alternative irrigation resource. METHODS AND RESULTS: The nutrients supplied in the waste nutrient solution consisted of 1474.5, 1285.1, 991.6, and 872.6 mg/L for $K+$, ${NO_3}^-$, $Ca^{2+}$ and ${SO_4}^{2-}$, respectively. At 56 days after transplanting (DAT), the leaf length of Chinese cabbage plants irrigated with the waste nutrient solution treatment was significantly higher than that of plants irrigated using a conventional groundwater treatment. Additionally, the leaf width, fresh weight and dry weight of the plants irrigated with the waste nutrient solution were similar or greater than that of plants irrigated with a conventional treatment. Furthermore, the growth of plants treated with the waste nutrient solution +25% fertilizer was the highest among all tested treatments. CONCLUSION(s): These results indicate that the waste nutrient solution can be used as an alternate water resource for crop cultivation. In addition, it can contribute to reduce the fertilizer and to obtain the higher crop yield of Chinese cabbage.

The feeding habits of yellow goosefish Lophius litulon and John Dory Zeus faber were studied by analyzing the stomach contents of specimens collected in the South Sea of Korea. In total, 132 hauls were taken during six experimental trawl survey (Tamgu 1) cruises conducted on a seasonal basis (March 2005-October 2007). The main prey items of the two species were similar. Fishes and crustaceans were the most important prey, with neither species showing ontogenetic changes in preferred species. Specifically, Pennahia argentata was the preferred prey item of L. litulon, whereas Trichiurus lepturus and Engraulis japonicus were preferred by Z. faber. Larger Z. faber (>24 cm) preferred bigger prey such as T. lepturus and Larimichthys polyactis, while smaller Z. faber preferred E. japonicus and Acropoma japonicum.
