BACKGROUND: Epigenetic regulation may be involved in modulation of gene expression during the normal cyclic changes of the human endometrium. We investigated expression of DNA methyltransferases (DNMTs) in endometrium during the menstrual cycle and the influence of sex steroid hormones on DNMT in endometrial stromal cells (ESC) in culture. METHODS: Expression of DNMT1, DNMT3a and DNMT3b was assessed by immunohistochemistry and real-time RT-PCR in endometrial tissue (n = 42 women). ESC (n = 3 wom

Gestational choriocarcinoma is a malignant tumor derived from placental trophoblast and the most aggressive member of gestational trophoblastic disease (GTD). Apoptosis-stimulating protein of p53-2 (ASPP2) is a member of ASPP family that transactivates p53 and thereby functions as a tumor suppressor. In this study, the expression profile of ASPP2 in choriocarcinoma was examined in comparison with normal placentas and hydatidiform moles, the latter being a type of GTD that carries malignant poten

Rheumatoid arthritis (RA) is a common disease characterized by chronic inflammation and irreversible destruction of articular cartilage and bone. In this report, we examined the anti-inflammatory and anti-arthritic effects of a novel leflunomide analogue, UTL-5b (also known as GBL-5b), for potential RA treatment. Using a carrageenan-induced edema study in rats, UTL-5b exhibited a better anti-inflammatory effect as compared with leflunomide and its metabolite. The chronic efficacy of UTL-5b was e

For the last several years, US citizens have been experiencing severe threats of terrorism. While such threats can significantly impact important factors for effective government operations such as citizens’ information demand and attitude toward the government, little is known about their potential effect on citizens’ acceptance of e-Government services. In order to fill this gap, this study examines the effects of perceived risks of terrorism and trustworthiness of the government, on citizens’

본 연구는 삽화적 미래사고 구체성과 불안 및 우울 간의 관계를 탐색하였다. 범불안과 관련이 높은 심리적 변인들의 영향을 배제한 후에도 삽화적 미래사고 구체성이 범불안 수준과 유의미한 연관성을 보이는지 살펴보았으며, 삽화적 미래사고 구체성과 우울 간의 관계 및 삽화적 미래사고를 구체적으로 떠올리는 데 영향을 미치는 변인들을 확인하였다. 참여자 165명(남 58명, 여 107명, 평균 연령 24.5세)을 대상으로 미래의 부정적인 상황, 부정적인 상황에 대처하는 상황, 긍정적인 상황을 구체적으로 기술하도록 하였고, 개정된 자서전적 면담 체계를 기반으로 각 조건별 삽화적 미래사고 구체성 수준을 평정하였다. 범불안과 우울 수준을 측정하기 위해 범불안장애 7문항 척도(GAD-7) 및 한국판 역학연구센터 우울척도(K-CES-D)를 사용하였다. 위계적 회귀분석 결과, 미래의 부정적인 상황에 대한 삽화적 미래사고 구체성은 우울 및 걱정의 설명량을 통제한 후에도 범불안 수준을 추가적으로 설명하였다.

서평 '복잡성'으로서의 일본/일본인 이한정 (상명대학교) 일본의 근대화는 서양과 조우하면서 시작되었다.18세기에 네덜란드 학문이라 일컫는 난학(蘭學)이 서양의 학문으로 일찍이 일본에 유입된 일 은 있었으나, 경제, 사회제도, 문화 등 서양 문명 전반을 일본이 총체적으 로 받아들인 것은 19세기 중반 이후부터다.이 과정에서 서양 문물을 맹목 적으로 받아들이는 일본인의 모습을 서양인들은 '원숭이 흉내'라는 표현 을 사용하여 묘사했다.1883년에 외국인 접대소의 명목으로 도쿄 한복판 에 세워진 서양식 건물 로쿠메이칸(鹿鳴館)에서는 불야성을 이루며 서양 인과 일본인이 어우러진 화려한 연회와 무도회가 개최되었고, 여기에 참 석하는 일본인은 서양식 연미복이나
