BACKGROUND: Intracranial atherosclerosis is associated with frequent stroke recurrence. High resolution vessel wall magnetic resonance imaging (HRMRI) can provide atheroma information related to its vulnerability. AIMS: We performed HRMRI in stroke patients with intracranial atherosclerosis to determine whether plaque characteristics from vessel wall imaging can predict future stroke recurrence. METHODS: Between July 2011 and June 2013, acute stroke patients with symptomatic intracranial atheros

Electrochromic devices (ECDs) exhibit significant potential as emerging electronics for applications associated with smart windows. They can dynamically control solar radiation consumption in buildings and vehicles to enhance efficiency. However, because smart windows are not optimized for high performance, and most are manufactured based on glass form, the large-area manufacturing process is complex and hinders its applicability to electrochromic (EC) devices. In this study, an ECD was fabricat

Shorter limb length was associated with lower childhood socioeconomic status, as estimated by the presence/duration of formal education. It was also independently associated with dementia and Alzheimer's disease. Sex differences in this association might be explained by gender disadvantage in early life for this cohort or by different associations with health states (for example, cardiovascular disease) later in life.

Patients with advanced stage adult MMD tended to have ischaemic lesions involving the cortex and posterior part of the brain and the stroke mechanism in these patients was largely associated with haemodynamic compromise. Our results suggest that the lesion pattern of ischaemic stroke may change along with the extent of arterial involvement.

Vulnerable symptomatic plaque as determined by a high-resolution magnetic resonance imaging technique is associated with artery-to-artery embolic infarction.This novel imaging technique can provide information about intracranial atherosclerosis in vivo, which can predict the infarction pattern.

Predialysis BUN is related to RLS symptom severity. Further studies on the underlying mechanism are needed.

본 연구는 중학생의 주의집중 문제와 학교생활적응의 관계에서 우울이 미치는 영향을 알아보기 위해 수행되었다. 이러한 연구 목적을 위해 설정된 연구문제는 다음과 같다. 첫째, 주의집중 문제와 우울, 주의집중 문제와 학교생활적응, 우울과 학교생활적응은 상관이 있는가? 둘째, 주의집중 문제와 학교생활적응 간의 관계에서 우울은 매개효과를 나타내는가? 연구 자료는 한국청소년정책연구원의 『한국 아동청소년 패널조사(KCYPS)』 중1 패널 2차년도 자료를 활용하였다. 전국에서 표집 된 중학교 2학년 2248명이 연구대상이었다. 변인 간 관계를 파악하기 위해 상관분석을 실시하였고, 우울이 주의집중 문제와 학교생활적응 간의 관계에 매개효과를 가진다는 모형을 검증하기 위해 구조방정식을 사용하였다. 연구 결과 첫째, 주의집중 문제와 우울은 정적인 상관관계, 주의집중 문제와 학교생활적응은 부적인 상관관계, 우울과 학교생활적응은 부적인 상관관계가 있었다. 둘째, 구조모형 분석 결과 주의집중 문제와 학교생활적

Advanced gastric cancer is one of the most aggressive gastrointestinal malignancies, and ADAM (A disintegrin and metalloproteinase)-9 is a cell-surface membrane glycoprotein with oncogenic properties that is overexpressed in several cancers. Herein, we investigated the biologic mechanism of ADAM9 in the progression, proliferation, and invasion of gastric cancer. First, we detected ADAM's expression, processing, and protease activity in gastric cancer cells. Protease activity was moderately corre
