Adipose sirtuin 6 drives macrophage polarization toward M2 through IL-4 production and maintains systemic insulin sensitivity in mice and humans

Song, Mi-Young,Kim, Sang Hoon,Ryoo, Ga-Hee,Kim, Mi-Kyung,Cha, Hye-Na,Park, So-Young,Hwang, Hong Pil,Yu, Hee Chul,Bae, Eun Ju,Park, Byung-Hyun Nature Publishing Group UK 2019 Experimental and molecular medicine Vol.51 No.5

<▼1><P>Adipose tissue inflammation is a reproducible feature of obesity and obesity-linked insulin resistance. Although sirtuin 6 (Sirt6) deficiency has previously been implicated in diet-induced obesity and systemic insulin resistance, the adipocyte-specific role of Sirt6 in the regulation of adipose tissue inflammation and systemic metabolic dysfunction in mice fed normal chow and in humans remains elusive. Here, using <I>Adipoq-Cre</I>-mediated adipocyte-specific Sirt6 knockout (aS6KO) mice, we explored whether adipocyte Sirt6 inhibits adipose tissue inflammation and its underlying mechanism. aS6KO mice fed normal chow gained more body weight and fat mass than wild-type mice and exhibited glucose intolerance and systemic insulin resistance. Measurement of plasma and tissue cytokines and flow cytometric analysis of adipose stromal vascular cells indicated a decrease in alternatively activated M2 macrophages in the adipose tissue of aS6KO mice. Mechanistically, Sirt6 regulated the expression of the canonical type 2 cytokine IL-4 by adipocytes in a cell autonomous manner, which in turn affects M2 macrophage polarization. Consistent with animal experimental data, the degree of obesity and insulin resistance demonstrated by the body mass index, fasting blood glucose and HbA1c correlated negatively with the expression of Sirt6 in human visceral fat tissues. Collectively, these results suggest that adipocyte Sirt6 regulates body weight gain and insulin sensitivity independent of diet, and the increased IL-4 production by Sirt6 and resultant M2 polarization of adipose tissue macrophages may attenuate proinflammatory responses in adipose tissue.</P></▼1><▼2><P><B>Obesity and diabetes: A control protein in fat</B></P><P>A protein in adipose tissue (composed of fat cells) helps protect against inflammation and the development of resistance to insulin that develops in obesity and can lead to type 2 diabetes. Researchers in South Korea, led by Eun Ju Bae at Woosuk University, Wanju, and Byung-Hyun Park at Chonbuk National University, Jeonju, investigated the role of Sirt6 in mice and in human adipose tissue. Deleting the mouse gene that codes for Sirt6 in adipocytes promoted the impaired response to insulin and associated increase in blood glucose levels that are two key aspects of diabetes. Changes in biochemical signaling pathways controlling immune cells called macrophages were implicated in these effects and suggest an anti-inflammatory role for Sirt6. Analysis of human adipose tissue supported these findings. The research will help understand how obesity promotes type 2 diabetes.</P></▼2>

박건주,하정상,이준,도현철,박승권,서상덕,기병수,김진국 영남대학교 의과대학 1996 Yeungnam University Journal of Medicine Vol.13 No.1

1985년 8월부터 1996년 1월까지 중증근무력증으로 진단받은 환자 52례에 대한 임상적 고찰을 통하여 다음과 같은 결론을 얻었다. 1. 전체 환자 중 남자가 19례(35.8%), 여자가 33례(64.2%)이넜고 11세에서 20세 사이가 12례(23%)로 가장 높은 빈도를 보였다. 2. 환자의 초기증상으로는 안검하수, 복시 등의 안구증상이 37례(71.2%)로 가장 많았고 modified Osserman의 분류에 따라서도 가장 증상이 가볍고 약물치료에 잘 반응하는 1군이 36례(69.3%)로 가장 많았다. 3. 환자가 호소하는 증상의 비특이성과 회복과 재발을 거듭하는 질병의 특성으로 인해 발병이후 진단될 때까지의 시간은 비교적 오래 걸렸고 1년이상 경과하며 진단된 경우도 16례(30.8%)나 되었다. 4. 자가면역질환이 7.6%에서 동반되었는데 갑상선기능 항진증이 2례(3.8), 인슐린의존형 당뇨 2례(3.8%)였고 종격동 전산화 단층촬영소견에서 흉선의 비대가 의심되었던 환자는 6례(11.5%), 흉선종이 발견 되었던 경우는 3례였다. 5. 환자의 치료는 대부분 항콜린에스테라제나 부신피질호르몬을 병용하는 내과적 치료를 하였으며 약물의 치료에 반응이 미비하거나 악화되는 경우 혹은 종격동 전산화 단층촬영상에서 흉선의 이상 소견이 보인 경우에 2례(3.9%)에서는 흉선절제술이, 1례(1.9%)에서는 혈장여과요법이 추가 되었고 흉선절제술과 혈장여과요법이 같이 병합 치료된 경우도 3례(5.9%)있었다. 6. 전체 환자중 2명에서 자연치유의 경과를 보였으며 이들은 모두 1군이였다. 그리고 흉선절제술과 부신피질 호르몬 투여로 완치된 예가 1례있었다. The authors experienced 52 patients with myasthenia gravis who were diagnosed at the Department of Neurology, Yeungnam University Hospital from August 1985 to January 1996. The following results were obtained through diagnostic evaluation and treatment. 1. The ratio of male to female was 1:1.7 and the most prevalent age group was second decade. 2. The most common initial presentation symptom was ocular(71.2%) and the peak incidence group was stage I(69.3%) according to the modified Osserman's classification. 3. In 16 patients(30.8%), it took more than a year to diagnose due to symptoms which were relapsed and remitting. 4. Of 52 patients, 2 cases were associated with thyroid disease(3.8%) and 2 with insulin-dependent diabetes mellitus(3.8%). 5. All of those who received anticholinesterase and corticosteroid therapy were improved with the exception of 5 cases which were improved after thymectomy and/or plasmapheresis. 6. Spontaneous remission was occured in 2 cases(3.8%) of ocular myasthenia gravis. And 1 case of group II was cured through thymectomy and long-term corticosteroid therapy.

박선아,김선호,황윤찬,오병주,윤창,박영준,정선와,황인남,오원만 大韓齒科保存學會 2002 Restorative Dentistry & Endodontics Vol.27 No.4

The bleaching of discolored nonvital teeth is conservative treatement that satisfy the cosmetic desire. The most common method for this treatement, walking bleaching, is using 30% hydrogen peroxide and sodium perborate. Many alternatives are suggested for preventing the external cervical root resorption that is the common complication of the nonvital teeth bleaching with 30% hydrogen peroxide. The same extent of oxidation reactions as that resulted by the bleaching with the application of 30% hydrogen peroxide and sodium perborate can also be acquired more safely by materials that contain 10% carbamide peroxide, used primarily for the bleaching of vital teeth. Therefore, this study was performed to evaluate the efficacy of 10% and 15% carbamide peroxide bleaching gel in nonvatal teeth bleaching. The internal bleaching of intentionally discolored teeth was performed in vitro with 10% carbamide peroxide (Group 1), 15% carbamide peroxide (Group 2), mixture of distilled water and sodium perborate (Group 3), and mixture of 30% hydrogen peroxide and sodium perborate (Group 4). The bleaching materials were refreshed following 3, 6, 9 and 12 days. To evaluate the bleaching effect, the color change of the crowns was measured at 1, 2, 3, 4, 7 and 15 days of bleaching using the colorimeter. The results were as follows : 1. L^* and ΔE^* values were increased with time in all bleaching agents(p<0.01). 2. There was no significant difference in L^* and ΔE^* value among bleaching agents. 3. Δ^* value higher than 3 was shown after 3 days of bleaching with 10% carbamide peroxide gel, 1 day with 15% carbamide peroxide gel, 4 days with mixture sodium perborate and distilled water and 4 days with mixture sodium perborate and 30% hydrogen peroxide, respectively. These results revealed that the use of 10% and 15% carbamide peroxide bleaching gel in non-vital teeth bleaching is as effective as mixture of distilled water and sodium perborate and mixture of 30% hydrogen peroxide and sodium perborate. Accordingly, carbamide peroxide could be used clinically to bleach discolored non-vital teeth.

이 연구는 개념생태 구성요소 중 학습자가 지닌 동기 · 심리적 관점의 측면에서 수행되었다. 즉 학습자가 학습동기와 관련하여 과학학습에 대한 개념을 어떻게 구성하고 있는가에 대하여 정성적인 방법으로 연구하였다. 수도권에 소재한 ‘가나’ 고등학교 2학년 학생 3명의 사례를 제시하였다. 연구의 신뢰도와 타당도를 위하여 자료의 수집과 분석 의 전과정 동안 삼각측정법을 사용하였다. 면담, 직접 및 간접 관찰, 문서를 통한 자료 수집을 하여 분석한 후, 사례 연구를 하였다. 연구 결과, 학습자들의 과학 학습에 대한 열정은 과학 학습에 대한 관점과 관련되는 것으로 나타났다. 과학 학습에 대한 학습자들의 관점은 지식의 본성, 학습의 본성, 인식론적 확신 근거를 포함한 과학 및 과학 수업에 대한 관점에 영향을 받았다. 이러한 과학학습관은 학습자들의 자아 효능과 과학학습 동기에 영햐을 주는 것으로 보여진다. While previous studies have recognized and have researched the resistance of students' scientific conception to change and the difficulty of the change of a conception's status, few have investigated the idea of conceptual ecology as a context of conceptual change learning, including the role that affective and motivational aspects might play when students are exposed to conceptual change learning. The present study was conducted to describe in detail high school students' views about learning and knowing science by summarizing of students' conceptual ecologies. The study was interpretive, using multiple data sources to achieve a triangulation of data. Three students from a public high school for boys serve as cases representative of students' views about learning and knowing science. Students' enthusiasm to pursue science was closely connected to their views about learning and knowing science. Students' views about learning and knowing science are influenced by their views regarding science and science class including the nature of knowledge, learning , and their epistemological commitments. They influence students' self-efficacy and motivation on learning science.

박병주,임흥빈,이학수 충북대학교 연초연구소 2006 煙草硏究 Vol.20 No.-

This study was carried out to compare humectant contents existed in tobacco shred from 69 cigarette brands being on sale in Korea. Humectant in tobacco shred were extracted by AOAC official method and analysed by gas chromatography. Mean value of glycerol, propylene glycol, and triethylene glycol contents from 69 cigarette brands were 13.6 ± 4.5 mg/g, 6.5 ± 2.6 mg/g, and 0.8 ± 0.2 mg/g, respectively. Humectant contents existed in tobacco shred of cigarette brands manufactured by small tobacco companies were relatively lower than that of the other four major tobacco companies in Korea. These results indicates that humectant contents in tobacco shred from cigarette have to determine periodically in order to give a basic information for quality evaluation of cigarette smoke in connection with smoking and healths, because it plays an important role the formation toxic cigarette smoke components. 본 실험은 국내에서 시판되고 있는 69종의 궐련담배 각초를 재료로 하여 실시하였다. 궐련담배 각초에 함유되어 있는 보습제의 함량을 측정하고 궐련담배 주류연의 tar 및 nicotine 함량을 측정하여 비교분석한 결과는 다음과 같다. 1. 국내에서 시판되는 귈련담배 각초 보습제 성분의 평균함량은 glycerol 13.6±4.5 mg/g, propylene glycol 6.5±2.6 mg/g, triethylene glycol 0.8±0.2 mg/g이었다. 2. 군소업체 귈련담배 각초에 존재하는 보습제 함량은 대규모업체에 비해 상대적으로 매우 낮은 수준을 유지하고 있었다
