Vespula rufa (Linnaeus, 1758), known as the red wasp, is a social wasp species. We analyzed the complete mitochondrial genome of V. rufa from South Korea, for an ongoing systematic study of the Korean Vespidae. This species is distributed in northern parts of North America, northern and central Europe, and parts of Asia. It can be distinguished from other species of the genus by usually having reddish brown areas on the 1st and 2nd tergites. The mitogenome is 17,663 bp in length, includes 13 protein-coding genes, 24 transfer RNA genes, and two ribosomal RNA genes. The nucleotide composition is 40.5% adenines, 43.00% thymines, 6.1% guanines, and 10.4 % cytosines.

Simplified Effective Compressive Strengths of Columns with Intervening Floor Slabs

Seung?Ho Choi,Jin?Ha Hwang,Sun?Jin Han,Hae?Chang Cho,Jae Hyun Kim,Kang Su Kim 한국콘크리트학회 2020 International Journal of Concrete Structures and M Vol.14 No.5

The current design codes discuss the effective compressive strengths of columns, which reflect a decrease in load transfer performance that can occur when columns and slabs have different concrete compressive strengths. The effective compressive strength of a column increases as it is confined by the slab, and the design codes mandate three different effective compressive strengths for interior columns (confinement on four sides), exterior columns (confinement on three sides), and corner columns (confinement on two sides). For both corner and exterior columns, the confinement effect of the slab is significantly smaller than that for the interior column, and there is a more marked decrease in load transfer performance. However, there is still a lack of theoretical studies investigating the effective compressive strengths of the corner and exterior columns. Therefore, based on the analysis model established in previous research, this study has proposed an equation for calculating the effective compressive strengths of the corner, exterior and isolated columns without any confinement effects of the slab. In addition, axial loading tests of isolated columns were conducted and the proposed equation was verified.

이승아;이현정;김도희;김옥현 박지애;김대진;정윤희;김경용;김성수;이원복 중앙대학교 의과대학 의과학연구소 2012 中央醫大誌 Vol.37 No.1/2

Autophagy is a highly regulated cellular mechanism that results in the bulk degradation process and which seems to be implicated in a variety of physiological and pathological conditions relevant to Alzheimer's disease (AD). Also, it has been suggested that the large part of autophagy is mediated by Light Chains 3 (LC3). Despite research suggesting an association between AD and autophagy, many issues remain to be addressed. To determine the relevance between autophagy and AD, we evaluated amyloid beta (Aβ) toxicity either in SH-SY5Y cells transfected with only EGFP or the cells exogeneously transfected with EGFP-LC3, mediating autophagy easily by overexpressed LC3. Without treatment of Aβ, the cell viabilities were quietly similar in both kinds of cells. The cell viability was decreased significantly in LC3 overexpressed cells. Consistently, more increased oxidative stress was detected in LC3 overexpressed cells. These results suggest that autophagy enhanced Aβ toxicity by way of increasing oxidative stress at least in part. This study will be of help to understand the role of autophagy in neurodegenerative diseases.

<P>We have described a new and promising strategy for the fabrication of composite and porous photonic crystal microparticles that combines the self-assembly of colloidal particles with photolithography techniques. We fabricated silica/SU-8 composite microparticles with photonic bandgaps <I>via</I> four steps: (1) deposition of the silica colloidal crystals on the photoresist, (2) embedding of the colloidal crystals in the photoresist, (3) UV exposure through a photomask and subsequent development, and (4) release of the microparticles from the substrate. Embedding was performed above the glass transition temperature (<I>T</I><SUB>g</SUB>) of uncrosslinked SU-8. At such temperatures, capillary forces on the silica particles facilitate the migration of colloidal crystals in the SU-8 matrix. Particle migration ceased when the top colloidal crystal layer was trapped at the interface between air and SU-8. In addition, we also prepared porous microparticles with an inverse opaline structure by dissolving the embedded silica particles from the composite structures. The porous microparticles showed enhanced reflectivity at the bandgap position due to the large refractive index contrast. The bandgap position of the microparticles was controlled by the size of the silica particles, which determined the lattice constant. Bilayered composite and porous microparticles with two distinct photonic bandgaps were also prepared by sequential deposition of colloidal crystals composed of two differently sized silica particles.</P> <P>Graphic Abstract</P><P>A new and promising fabrication strategy of photonic crystal microparticles was demonstrated by combining colloidal self-assembly with photolithography. <IMG SRC='http://pubs.rsc.org/services/images/RSCpubs.ePlatform.Service.FreeContent.ImageService.svc/ImageService/image/GA?id=c0cp00134a'> </P>

세계인구 43억명 중 B형 간염 바이러스 보균자는 2억 1천 5백만명이며 이중 78%인 1억 6천만명 이상이 아시아 대륙에 집중되어 있다. 한국도 B형 바이러스 간염의 침윤지대이다. 본 연구는 B형 바이러스 보균자 혹은 만성간염을 치료할 수 있는 생약제를 탐색할 목적의 일환으로 한국에서 시판하는 생약제 151종을 구입하여 증류수로 추출하고 여과한 후 냉동건조하여 HBs 항원에 대한 결합능, HBV DNA polymerase억제능, tumor necrosis factor(TNF) 유리에 미치는 영향, 그리고 galactosamine 유발 간염에 대한간장보호 작용을 조사하였다. 151종의 생약제중 0.16㎍/㎖ 농도에서 간염 vaccine 내에 함유된 HBs 항원과 결합하는 생약제는 지유, 가자, 복분자, 대황, 정향, 빈량, 산수유, 소목, 마황, 쇄양, 후박, 목과, 양강, 오약, 산사, 목단피 등 16종이었다. 이들 생약제중 대황(Rheum palmatum L. 大黃), 가자(Terminalia chebula R. 訶子), 지유(Sanguisorba officinalis L. 地楡), 복분자(Rubus coreanus M. 覆盆子)는 HBV DNA polymerase 활성도를 비교적 강하게 억제하였으며 빈량(Areca catechu L. 빈랑), 정향(Eugenia caryophyllata T. 丁香), 목과(Chaenomeles japonica L. 木瓜), 산수유(Cornus officinalis S. 山茱萸)는 약하게나마 HBV DNA polymerase 활성을 억제하였다. 또한 HBV DNA polymerase를 억제한 대황, 가자, 지유, 복분자, 빈량, 정향, 마황, 소목, 산수유를 대상으로 TNF 유리에 미치는 영향을 조사한 결과 소목을 제외한 8종의 생약제 모두가 대식세포를 자극하여 TNF를 유리시켰다. 그리고 장차 임상에 사용함을 전제로 HBV DNA polymerase를 억제한 대황, 가자, 지유, 복분자, 빈량, 정향, 마황, 소목, 산수유를 galactosamine 유발 간염(백서)에 투여하여 간기능 검사에 미치는 효과를 조사하였으나 간기능 검사상으로는 특별한 보호작용을 나타내지 못하였으며 생약제 단독 투여로서는 간기능에 대하여 나쁜 영향을 주지 않았다. Hepatitis B virus infection is major cause of acute and chrome hepatitis, cirrhosis of liver, and hepatocellular carcinoma. There are over 200 million carriers of hepatitis B virus in the world, nearly 80 % of whom live in the South East Asia, Korea is also highly endemic area of hepatitis B virus infection. This study was performed to evaluate the effect of extracts of traditional Korean herbal medicines on hepatitis B virus. 151 traditional herbs were extracted, filtered and lyophilized. Using 151 herbal extracts we tested binding capability to the HBs Ag, inhibition of HBV DNA polymerase, release of tumor necrosis factor (TNF), and protection against galactosamine induced liver damage. Among 151 herbs, 16 herbs (Sanguisorba officinalis L., Terminalia chebula R., rubus coreanus M., Rheum palmatum L., Eugenia caryophyllata T., Areca catechu L., Cornus officinalis S., Caesalpinia sappan L, Ephedra sinica S., Cynomorium songaricum R., Machilus thunbergii S., Chaenomeles japonica L., Alpinia officinarum H., Lindera strychnifolia V., Crataegus pinnatifida B., Paeonia suffruticasa A. ) had binding capability to HBs Ag which contained in the commercial hepatitis vaccine, at 16 ug/㎖ of concentratioa Among the above 16 herbs, Rheum palmatum L., Terminalia chebula R., Sanguisorba officinalis L., Rubus coreanus M. significantly inhibited the HBV DNA polymerase activity, and Areca catechu L., Eugenia caryophyllata T., Ephedra sinica S., Caesalpinia sappan L., Chaenomeles Japonica L., Cornus officinalis S. also inibited the HBV DNA polymerase activity but less effective. All of the herbs, except Caesalpinia sappan L., which inhibited the HBV DNA polymerase activity, actively stimulated the mononuclear cells to release tumor necrosis factor(TNF) in whole blood culture system. The herbs which inhibited the HBV DNA polymerase activity, did not show any protective effect in galactosamine-induced hepatitis in rats, but there was no direct toxic effect when herbs were administered alone.

Agranulocytosis, one of the major side effects of antithyroid a gents, probably occurs in less than 0.25% of cases treated with antithyroid agents. It usually occurs within the first several weeks or months after the initiation of therapy, when drug dosage is higher. Most reported cases of agranulocytosis have occurred during the first 3 months of therapy. We describe here a rare case that did not experience the side effect for 6 years of antithyroid agent treatment but presented with agranulocytosis in one month after re-exposure. It suggests that the major side effect such as agranulocytosis can occur in patients who had undergone prior uneventful antithyroid drug therapy.
