Seo, Hee-Won,Kim, Eun-Jin,Na, Hyelin,Lee, Mi-Ock Elsevier 2009 FEBS letters Vol.583 No.1

<P><B>Abstract</B></P><P>The interplay between hypoxia-inducible factor-1α (HIF-1α) and histone deacetylase (HDACs) have been well studied; however, the mechanism of cross-talk is unclear. Here, we investigated the roles of HDAC4 and HDAC5 in the regulation of HIF-1α function and its associated mechanisms. HDAC4 and HDAC5 enhanced transactivation by HIF-1α without stabilizing HIF-1α. HDAC4 and HDAC5 physically associated with HIF-1α through the inhibitory domain (ID) that is the binding site for factor inhibiting HIF-1 (FIH-1). In the presence of these HDACs, binding of HIF-1α to FIH-1 decreased, whereas binding to p300 increased. These results indicate that HDAC4 and HDAC5 increase the transactivation function of HIF-1α by promoting dissociation of HIF-1α from FIH-1 and association with p300.</P><P><B>Structured summary:</B></P><P>MINT-6802187:</P><P><I>HIF1 alpha</I> (uniprotkb:Q16665) <I>physically interacts</I> (MI:0218) with <I>FIH1</I> (uniprotkb:Q9NWT6) by <I>anti bait coimmunoprecipitation</I> (MI:0006)</P><P>MINT-6802058:</P><P><I>HIF1 alpha</I> (uniprotkb:Q16665) <I>physically interacts</I> (MI:0218) with <I>HDAC4</I> (uniprotkb:P56524) by <I>pull down</I> (MI:0096)</P><P>MINT-6802021:</P><P><I>HIF1 alpha</I> (uniprotkb:Q61221) <I>physically interacts</I> (MI:0218) with <I>HDAC4</I> (uniprotkb:P56524) by <I>anti bait coimmunoprecipitation</I> (MI:0006)</P><P>MINT-6802036:</P><P><I>HIF1 alpha</I> (uniprotkb:Q61221) <I>physically interacts</I> (MI:0218) with <I>HDAC5</I> (uniprotkb:Q9UQL6) by <I>anti bait coimmunoprecipitation</I> (MI:0006)</P><P>MINT-6802102:</P><P><I>HIF1 alpha</I> (uniprotkb:Q16665) <I>physically interacts</I> (MI:0218) with <I>HDAC5</I> (uniprotkb:Q9UQL6) by <I>pull down</I> (MI:0096)</P><P>MINT-6802121, MINT-6802156:</P><P><I>P300</I> (uniprotkb:Q09472) <I>physically interacts</I> (MI:0218) with <I>HIF1 alpha</I> (uniprotkb:Q16665) by <I>anti bait coimmunoprecipitation</I> (MI:0006)</P>

<P><B>Abstract</B></P><P>Calmodulin-regulated protein phosphorylation plays a pivotal role in amplifying and diversifying the action of calcium ion. In this study, we identified a calmodulin-binding receptor-like protein kinase (CBRLK1) that was classified into an S-locus RLK family. The plasma membrane localization was determined by the localization of CBRLK1 tagged with a green fluorescence protein. Calmodulin bound specifically to a Ca<SUP>2+</SUP>-dependent calmodulin binding domain in the C-terminus of CBRLK1. The bacterially expressed CBRLK1 kinase domain could autophosphorylate and phosphorylates general kinase substrates, such as myelin basic proteins. The autophosphorylation sites of CBRLK1 were identified by mass spectrometric analysis of phosphopeptides.</P><P><B>Structured summary</B></P><P>MINT-6800947:<I>CBRLK1</I> (uniprotkb:Q9ZT06) and <I>AtCaM2</I> (uniprotkb:P25069) <I>bind</I> (MI:0407) by <I>electrophoretic mobility shift assay</I> (MI:0413)</P><P>MINT-6800966:<I>AtCaM2</I> (uniprotkb:P25069) and <I>CBRLK1</I> (uniprotkb:Q9ZT06) <I>bind</I> (MI:0407) by <I>competition binding</I> (MI:0405)</P><P>MINT-6800930:<I>CBRLK1</I> (uniprotkb:Q9ZT06) <I>binds</I> (MI:0407) to <I>AtCaM2</I> (uniprotkb:P25069) by <I>far Western blotting</I> (MI:0047)</P><P>MINT-6800978:<I>AtCaM2</I> (uniprotkb:P25069) <I>physically interacts</I> (MI:0218) with <I>CBRLK1</I> (uniprotkb:Q9ZT06) by <I>cytoplasmic complementation assay</I> (MI:0228)</P>

김성은,이선영,신정은,주미순,전정현,이경은 이화여자대학교 의과대학 2003 EMJ (Ewha medical journal) Vol.26 No.2

Objectives : This study is to compare the clinical and cost effectiveness of various pharmacologic therapies with of without endoscopic procedure in the Forrest II ulcer. Methods : Between May 2001 and June 2002, total of 58 Forrest II bleeding activity patients (37 cases of NBVV, 6 adherent blood clots, 9 flat red spot, and 6 flat black spot) with gastric ulcer(32 cases) and duodenal ulcer(26 cases) were analyzed. UGI endoscopy was performed within 12 hours of the first bleeding episodes, and underwent repetitive endoscopy after 48h. All the patients were randomly assigned to receive somatostatin(group I), PPI(omeparzole : group II), only H2 blocker (famotidine, group III), or endoscopic injection therapy followed by famotidine (group IV). We compared with rebleeding rates, changes of ulcer size, and modified estimated costs for 3 day-hospital in four groups respectively. Results : 1) Twelve patients experienced rebleeding(20.7%). 2) The rates of rebleeding were 16.6% (2/12) in group I, 28.6%(4/14) in group II, 5.9%(1/17) in group III, 26.7% in group IV. There was no significant difference in rebleeding rate among the groups, but there was low rebleeding tendency in group III, compared with group II(p=0.087).3)Type of stigmata including non-bleeding visible vessels and adherent clots were associated with an increased rate of recurrent bleeding(p=0.01).4) When modified estimated costs were calculated, group III could be treated at the lowest cost(p<0.05). Conclusion : In Forrest II bleeding ulcer, medical therapy, especially famotidine could be suggested prudently as a proper treatment modality for this lesion, considering the cost-effecti-veness. 목적: 위십이지장의 궤양성 출혈은 대부분 특별한 치료없이 보존적인 치료만으로 지혈된다. 그러나 활동성 출혈이 있는 Forrest II 궤양의 경우는 흔히 내시경적인 치료를 하게 되는데 최근 여러 연구에서 약물치료와 비교 연구가 있었으나 다양한 약물들과 내시경 치료의 효과 및 비용-효용성의 비교는 이루어지지 않았다. 방법: 2001년 5월부터 2002년 6월가지 Forrest II 궤양출혈 환자 68명을 전향적으로 포함시켰고 이중 위암으로 진단된 경우와 내시경의 추적 검사를 거부한 경우 또는 다른 중증의 내과적 질환이 동반된 경우를 제외시켜 58명의 환자를 대상으로 하였다. 대상 환자 58명은 위궤양이 32명이고 십이지장 궤양이 26명으로 비출혈성노출 혈관 37명, 신선 부착 혈괴 6명, 적색반 9명, 그리고 흑색반 6명이었다. 초기 상부 위장관 내시경은 내원 후 12시간 이내에 이루어졌고 추적 검사는 48시간 이후에 시행되었다. 치료는 네 개의 군으로 나누어 무작위로 소마토스타틴 투여군(1군), 프로톤펌프 억제제 투여군 (2군), H₂수용체 차단제 투여군(3군), 그리고 내시경적 지혈제 주사군(4군)으로 치료하였고 각 군의 재출혈 여부, 혈압, 수혈, 궤양의 크기, 급성 출혈 흔적 등을 비교 관찰하였고 입원 3일간의 입원치료비용을 계산하였다. 결과: 1) 재출혈은 12명(20.7%) 에서 발생하였다. 2) 각군에서의 재출혈은 제1군이 16.6%(2/12), 제2군에서 28.6%(4/14), 제3군이 5.9%(1/17), 제4군이 26.7%(4/15)로 각 군의 재출혈 빈도는 차이가 없었으나 제3군에서 제2군에 비해 재출혈이 낮은 경향을 보였다.(p=0.087).3) 재출혈에 영향을 미치는 인자는 노출 현환과 신선 혈괴였다(p=0.01). 4)평균 입원치료 비용은 제3군이 가장 적어 높은 치료 비용-효과를 보였다.(p<0.05).

Interlanguage Development in English Interrogatives by Two Korean Children

Yang, Eun Mi 대한언어학회 2000 언어학 Vol.8 No.1

Yang, Eun-Mi. 2000. Interlanguage Development in English Interrogatives by. Two Korean Children. Linguistics 8-1, 379-401. The purpose of this research is to compare the development of English question formation by the two Korean children who were attending elementary school and acquiring English in America for about 1 year and whose age difference is two years. (One is 7 years and the other is 9 years old then.) They were acquiring English mainly at school in natural environment and used Korean after school at home. Through this study I examined some prevailing hypothesis which argues for that older children are faster than younger children in acquiring second language and studied the order of acquisition of English structures according to age differences. This longitudinal study showed that both of them used 'overgeneralization' strategy for processing their interlanguage and produced systematic and rule-governed question forms, which support the hypothesis that universal cognitive mechanisms of strategies are the basis for the child's organization of the L2 system.

Humanistic Approach in EFL Classes

Seo, Eun-mi 대한언어학회 2000 언어학 Vol.8 No.3

Seo Eun-mi. 2000. Humanistic Approach in EFL Classes. Journal of the Linguistic Association of Korea, 8(3), 109-122. Humanistic education comes from humanistic psychology which emphasizes the inner nature of person. Humanistic approach is learner-centered since learners' feelings and emotions are considered important. In the humanistic classroom, students like to work in pairs and groups to share their experiences and memories in a very comfortable atmosphere. In this paper, I researched the effects of humanistic education and how teachers can use various activities to motivate shy Korean students. It is highly recommended to use this method in the EFL classroom. (Howon University)

Gender, Communication and Culture

Seo, Eun Mi 대한언어학회 1997 언어학 Vol.5 No.1

Seo, Eun-Mi. 1997. Gender, Communication and Culture. Linguistics, 5-1, 45-56. Gender and communication are very interesting topic in sociolinguistics. There have existed communication problems between males and females because they have different communication styles. They also have different gender culture. It is important to accept differences between males and females in communication to avoid communication problems. In this paper, the researcher tried to make clear about the culture, gender and communication. Recommendations for successful communication are suggested. (Chonbuk Sanup University)

A study on health and hygiene needs, strategies, and well‐being of an Aeta indigenous community in the Philippines through photovoice methods

Yang Eun‐Mi,Kim Jwakyum,Biag Al,Mangulabnan Jefferson,Dela Cruz Arlan,Sarmiento Philip Joseph 한국사회복지학회 2020 Asian Social Work and Policy Review Vol.14 No.3

On a global scale, poor access to health and social welfare services for indigenous populations has threatened their overall well-being, especially those living in remote or peripheral areas. Academics from two higher education institutions in South Korea and the Philippines conducted a community-based research in an indigenous Aeta community in the highlands of Pampanga Province in the Philippines’ Central Luzon region. Using a photovoice method and community survey, they investigated family health and hygiene as well as the current strategies this indigenous community employs to address their concerns. Results revealed that the community lacks the basic human needs and services such as water, food, shelter, education, and health service. They demonstrated, however, resilience in managing their lives by making use of the available natural resources and by drawing strength from community spirit. This study provided insights on how higher education institutions and other concerned agencies craft initiatives intended to benefit vulnerable populations and underserved communities such as the indigenous peoples.

Repellent efficacy of essential oils and plant extracts against Tribolium castaneum and Plodia interpunctella

Lee Hwa‐Eun,Hong Su Jung,Hasan Najmul,Baek Eun Joo,Kim Jun Tae,Kim Young‐Duk,Park Mi‐Kyung 한국곤충학회 2020 Entomological Research Vol.50 No.9

This study was conducted to investigate the repellent efficacy of essential oils (Origanum vulgare, Pimpinella anisum, and Tanacetum cinerariifolium) and four plant extracts (Agastache rugosa, Capsicum annuum, Citrus reticulata, and Ginkgo biloba) against Tribolium castaneum (adults and larvae) and Plodia interpunctella (larvae). Gas chromatography/mass spectrometry analysis revealed the presence of carvacrol, anethole, and jasmolin I as the predominant constituent in O. vulgare, P. anisum, and T. cinerariifolium, respectively. Furthermore, ethyl hexopyranoside, 9,12‐octadecadienoic acid, cyclopentanol, and 2‐cresol were identified in A. rugosa, C. annuum, C. reticulata, and G. biloba, respectively. The repellent efficacy of each essential oil, plant extract, and the combination of oils was evaluated using a specially designed cylinder trap for 120 h. Among the three oils, O. vulgare and T. cinerariifolium had greatest repellent efficacy against P. interpunctella larvae. T. cinerariifolium exhibited effective repellence against the adults and larvae of T. castaneum. Therefore, O. vulgare (O) and T. cinerariifolium (T) were selected for further investigation of combined effects. Two essential oils were mixed in three different ratios of OT1 (1:3), OT2 (1:1), and OT3 (3:1). The repellent efficacies of OT1 and OT2 against the adults of T. castaneum were significantly greater than that of OT3. OT1 was effective against the larvae of T. castaneum, whereas OT2 was effective against the larvae of P. interpunctella. OT1 enhanced the repellent efficacy by approximately five times against larvae of T. castaneum, compared with that of T. cinerariifolium. Overall, OT1 was selected as the best repellent substance against all the tested insects.
