Elevated TRAF2/6 expression in Parkinson's disease is caused by the loss of Parkin E3 ligase activity.

Chung, Ji-Yun,Park, Hee Ra,Lee, Su-Jin,Lee, Sun-Hye,Kim, Jin Sik,Jung, Youn-Sang,Hwang, Sang Hyun,Ha, Nam-Chul,Seol, Won-Gi,Lee, Jaewon,Park, Bum-Joon United States and Canadian Academy of Pathology [e 2013 Laboratory investigation Vol.93 No.6

<P>Parkinson's disease (PD) is the second leading neurodegenerative disease, and is known to be induced by environmental factors or genetic mutations. Among the verified genetic mutations of PD, Parkin, isolated from the PARK2 locus, shows an autosomal recessive inheritance pattern and is known to be an E3 ligase. However, the physiological target of Parkin and the molecular mechanism of Parkin-deficiency-induced PD have not been clearly demonstrated until now. It has recently been proposed that inflammation, suggesting as a causal factor for PD, is enhanced by Parkin deficiency. Thus, we examined the relationship between inflammation-related factors and Parkin. Here, we provide the evidence that Parkin suppresses inflammation and cytokine-induced cell death by promoting the proteasomal degradation of TRAF2/6 (TNF-α receptor-associated factor 2/6). Overexpression of Parkin can reduce the half-lives of TRAF2 and TRAF6, whereas si-Parkin can extend them. However, mutant Parkins did not alter the expression of TRAF2/6. Thus, loss of Parkin enhances sensitivity to TNF-α- or IL-1β-induced JNK activation and NF-κB activation. Indeed, si-Parkin-induced apoptosis is suppressed by the knockdown of TRAF6 or TRAF2. We also observed elevated expression levels of TRAF6 and a reduction of IκB in an 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine-induced PD mouse model. Moreover, elevated expression levels or aggregation of TRAF6 were detected in approximately half of the human PD tissues (7/15 cases) and 2 cases, respectively. In addition, TRAF6 and Parkin expression levels show a reverse relationship in human PD tissues. Our results strongly suggest that the reduction of Parkin or overexpression of TRAF2/6 by chronic inflammation would be the reason for occurrence of PD.</P>

이재한(Jae-Han Lee),최하연(Ha-Yeon Choi),박성용(Seong-yong Park),천진혁(Jin-Hyuk Chun),강윤구(Yun-Gu Kang),윤여욱(Yeo-Uk Yun),이기범(Gibum Yi),오택근(Taek-Keun Oh) 한국토양비료학회 2021 한국토양비료학회 학술발표회 초록집 Vol.2021 No.11

암모니아(NH₃)는 대기 중 황산화물(SOx), 질소산화물(NOx) 등과 반응하여 황산암모늄, 질산암모늄과 같은 2차 미세먼지를 생성하는 주요 미세먼지 원인물질이다. 2017년 기준 국내에서 NH₃는 총 308,298 ton year<SUP>-1</SUP> 배출되었으며, 농업부문에서 약 79.3%의 비율로 가장 많이 배출되었다. 토양에 질소질 비료의 시용 시 발생되는 NH₃의 대기로 배출은 토양 내 질소 손실의 원인이 되기도 한다. 바이오차는 넓은 표면적과 표면의 작용기를 가지고 있어 토양 내에서 중금속이나 오염물질 등을 제거하는 특징이 있다. 본 연구는 다양한 온도에서 열분해된 맥주박 바이오차 처리가 NH₃ 배출량에 미치는 영향을 평가하기 위해 실시하였다. 바이오차는 충분히 건조된 맥주박을 300, 500, 700°C에서 각각 1시간 동안 열분해하여 제조하였다. 각 바이오차를 토양에 3% (w w<SUP>-1</SUP>)씩 혼합 후 NH₃ 포집을 위해 자체 제작한 아크릴컬럼에 작토층 높이인 20 cm 까지 토양을 채웠으며, 토양 수분함량은 20%로 조절하였다. 질소질 비료는 작물별 시비처방기준의 배추를 기준으로 요소를 각 처리구에 320 kg ha<SUP>-1</SUP>로 처리하였다. NH₃의 포집은 요소 처리 후부터 약 30일간 실험실 내에서 실시하였다. 배출되는 NH₃는 0.05 N H₂SO₄으로 포집하여, Indophenol blue method로 비색정량하였다. 그 결과, 시험 기간 중 총 NH₃ 배출량은 BB<SUB>700</SUB>처리구가 약 11.83 kg ha<SUP>-1</SUP>로 가장 높게 나타났다. BB<SUB>300</SUB>처리구의 총배출량은 약 7.34 kg ha<SUP>-1</SUP>로 가장 낮았으며, N처리구에 비해 약 30.5% 저감 되었다. BB<SUB>700</SUB>처리구는 N처리구에 비해 NH₃ 총배출량이 약 12% 증가하였는데, 이는 바이오차의 높은 pH에 의한 alkali effect로 판단된다. 실험 후 토양 분석 결과, 모든 바이오차 처리구에서 pH, EC, Av. P₂O<SUB>5</SUB>, T-C, T-N 등이 증가하였다. 특히, BB<SUB>700</SUB>처리구는 처리된 바이오차의 높은 탄소 함량으로 인하여, 토양 내 탄소 함량이 약 3.44%로 가장 높았다. 따라서, 비교적 낮은 온도에서 열분해한 BB<SUB>300</SUB>의 토양 처리가 농경지에서 배출되는 NH₃를 감축할 수 있으며, 본 연구 결과는 실제 농경지에서 배출되는 NH₃를 감축하기 위한 기초자료로 사용될 수 있을 것으로 판단된다.

The octadodecanoxy derivative of the phthalocyanine which has such long hydrocarbon chains around the skeleton of the phthalocyanine was synthesized. First of all, ortho-catechol was treated with 2 moles of 1-bromododecane to yield ortho-didodecanoxybenzene(I). Second, bromination of I resulted in dibromo-didodecanoxy benzene(II) where the para positions to the dodecanoxy groups were brominated. Finally, reaction of II with an excess of CuCN under an N₂atmosphere gave the intermediate dicyano-didodecanoxy-benzene(III), in situ, and futher heating in dry DMF with more CuCN gave the final product, octadodecanoxy derivative of the phthalocyanine. The synthetic method developed herein provides a general way to synthesize the variety of the phthalocyanines which displays many different substituents such as long hydrocarbons around its skeleton and contains a various metal inside of the phthalocyanine.

두 종류의 고리화 리간드가 배위된 이리듐 착물의 합성과 그 발광 특성 연구

朴貴蓮,河潤卿 弘益大學校 科學技術硏究所 2005 科學技術硏究論文集 Vol.16 No.-

The new types of iridium complexes with two kinds of (CˆN) ligands were designed and synthesized to improve the luminescence efficiency by avoiding triplet-triplet (T-T) annihilation. Ir(ppy)_(2)(piq) and Ir(ppy)_(2)(piq-F) were designed and prepared, where ppy, piq and piq-F represent 2-phenylpyridine, 1-(phenyl)isoquinoline and 1-(4'-fluorophenyl)isoquinoline, respectively. These heteroleptic complexes are expected to have a high luminescence efficiency by the intramolecular energy transfer from the energy absorbing ligand (ppy) to the luminescent ligand (piq derivatives), leading to a decrease on quenching or energy deactivation. Luminescent characteristics of the heteroleptic Ir complexes were inviestigated photophysically and compared with homoleptic Ir complexes, Ir(ppy)_(3), Ir(piq)_(3), and Ir(piq-F)_(3).

Health Risk Appraisal(HRA) is usually defined as a process by which we expect of individual's chances of death or acquiring specific diseases within a defined period of time. The concept of worksite as an area of health maintenance and promotion is newly developing. Our movement for health promotion of employees has been increasingly known in the worksite. The aim of this study is to develop health risk appraisal tools about health promotion at the worksite for employees. We performed this study by two steps; one step was to develop a HRA questionnaire of worksites in Korea, another was to evaluate the reliability of the questionnaire. For developing HRA questionnaire, we reviewed scientific examples at first, and then weighted the score by delphi. To evaluate the reliability of developed questionnaire, we carried out survey by test-retest method. A total of 131 employees completed HRA questionnaire on two times. The results are as follows. The total score of health risk in unhealthy workers was higher than that of healthy workers. The range of test-retest reliability of responses to the questionnaire was 0.57-0.94. Therefore it seems that this questionnaire was very suitable to assess the health behavior of workers. In conclusion, the developed HRA questionnaire can be used as a tool for evaluating health behavior and for providing health counseling materials.

본 연구는 레진 시멘트의 색 안정성을 평가하여, 레진 시멘트의 변색에 의한 심미 수복물의 실패의 가능성을 평가하고자 시행하였다. 4종의 이원중합형 레진 시멘트인 Panavia-F (PA; KURARAY), Duolink (DL; BISCO), Variolink II (VL; Ivoclar Vivadent),및 RelyX Unicem (UC; 3M ESPE)과 1종의 자가중합형 레진 시멘트인 Resiment Ready-Mix (with fluoride) CE (RM: j.l.Blosser)를 사용하였으며 , 대조군으로 복합레진 Gradia Direct (GD; GC)과 복합 레진 인레이용 Tecera Dentin A3 (TE; Bisco)를 사용했다. 각 재료 당 직경 6.5 ㎜, 두께 4.5 ㎜의 디스크형 시편 10개를 제작하였다. 중합 후 시편은 분광색채계측기인 Spectrolino (GretagMacbeth)를 이용해 CIE L^(*)a^(*)b^(*)값을 측정하고 가속시험을 위해 빛이 차단된 refrigerated bath circulator에서 60 ℃ 증류수에 30일간 보관 후에 색 측정을 시행하고, 시험 전 후의 색차를 계산하였다. 가속 시험 후 L^(*) 값은 감소하는 앙상을 보였고, a^(*) 값은 증가하는 양상을 보였지만 유의한 차이는 없었다. 반면 b^(*) 값은 유의하게 증가하였다 (p<0.05). TE가 15일과 30일 모두에서 가장 적은 색변화 (p < 0.05)를 보인 반면 GD는 15일 가속 실험 후 큰 색변화를 보였다. 30일 가속 실험 후 PA, VL, RM, DL 그리고 UC 순으로 ΔE^(*)값이 커졌으며 (p < 0.05), 30일 후 모든 레진시멘트들은 육안으로 변색을 인지할 수 있는 3 이상의 ΔE^(*) 값을 보였다. The purpose of this study was to evaluate the color stability of resin cements with accelerated test. Four dual curing resin cements: Panavia-F (KURARAY), Duolink (BISCO), Variolink-II (Ivoclar Vivadent), and RelyX Unicem (3M ESPE) and 1 self curing resin cement: Resiment CE (j. 1. Blosser) were used in this study. In control group, Gradia Anterior (GC) composite resin and Tescera Dentin (Bisco) indirect composite were used. Ten disk shape specimens were made from each resin cement. The specimens were subjected to an accelerated aging process in a refrigerated bath circulator at 60 ℃ for 15 and 30 days. Spectrophotometric analyses were made before and after 15 days and 30 days of accelerated aging time. The color characteristics (L^(*), a^(*), b^(*)) and the color difference (ΔE^(*)) of the specimens before and after immersion were measured and computed. Regardless of type of the resin cements, L^(*) value was decreased and a^(*) value was increased, but there were no significant difference. But b^(*) value was increased significantly (p < 0.05). Tescera inlay showed least color change (p < 0.05), but Gradia showed notable color change after 15 days. After 30 days on accelerated aging, ΔE^(*) value was increased (Panavia-F < Variolink-II < Resiment CE < Duolink < Unicem) (p < 0.05), but there were no significant difference among Panavia-F, Variolink-II, and Resiment CE groups. After 30 days of accelerated aging, ΔE^(*) value of all resin cements were greater than 3.0 and could be perceived by the human eye.
