Stem cells hold great potential as cell-based therapies to promote vascularization and tissue regeneration. However, the use of stem cells alone to promote angiogenesis remains limited because of insufficient expression of angiogenic factors and low cell viability after transplantation. Here, we have developed vascular endothelial growth factor (VEGF)(More)
We examined the prevalence, correlates, and comorbidities of adult attention-deficit hypersensitivity disorder (ADHD) symptoms in a Korean community using data from the National Epidemiological Survey of Psychiatric Disorders in Korea conducted in 2006. A total of 6081 subjects aged 18 to 59 years participated in this study. Diagnostic assessments were(More)
With a rapidly aging society, geriatric mental health is emerging as important public health concern. Despite the short history of psychiatric epidemiology in Korea, recently, epidemiologic data regarding geriatric psychiatric problems has started to accumulate. In the current study, we reviewed epidemiological findings regarding geriatric mental health in(More)
OBJECTIVE The prevalence of restless legs syndrome (RLS) and its relationship with the demographic variables in an older Korean population were examined. METHODS A face-to-face household survey was conducted in five different regions of Korea from June 2008 to August 2008. Among a total of 3074 individuals who were aged more than 65, 1990 participants(More)
BACKGROUND In previous studies, psoriasis has been reported to be associated with metabolic syndrome. OBJECTIVE The purpose of this study was to evaluate risk factors for metabolic syndrome in psoriasis patients and to compare the prevalence of metabolic syndrome in psoriasis and control groups. METHODS All patients (n=490) and controls (n=682) were(More)
Interactions of stem cells with biophysics of extracellular matrix (ECM) have shown a significant influence in control of the stem cell behavior. To mimic nanometer and micrometer scale of ECM structures, biomaterials such as nanotopographical substrates, nanofibers, conductive gold nanoparticles, carbon nanomaterials, hydrogels, and micropatterned surface(More)
Bone morphogenetic protein-2 (BMP-2) is used to promote bone regeneration. However, the bone regeneration ability of BMP-2 relies heavily on the delivery vehicle. Previously, we have developed heparin- conjugated fibrin (HCF), a vehicle for long-term delivery of BMP-2 and demonstrated that long-term delivery of BMP-2 enhanced its osteogenic efficacy as(More)
Plant growth promoting rhizobacteria Ochrobactrum lupini KUDC1013 and Novosphingobium pentaromativorans KUDC1065 isolated from Dokdo Island, S. Korea are capable of eliciting induced systemic resistance (ISR) in pepper against bacterial spot disease. The present study aimed to determine whether plant growth-promoting rhizobacteria (PGPR) strains including(More)
