Tissue-targeted delivery of small interfering RNA (siRNA) must be achieved before RNA interference (RNAi) technology can be used in practical therapeutic approaches. In this study, the potential of apolipoprotein A-I (apo A-I) for the systemic delivery of nucleic acids to the liver is demonstrated using real-time in vivo imaging. As a proof of concept, synthetic siRNAs against hepatitis B virus (HBV) were formulated into complexes of apo A-I and 1,2-dioleoyl-3-trimethylammonium-propane (DOTAP)/c

Recent advances in automated cell counters enable us to count cells more easily with consistency. However, the wide use of the traditional vital dye trypan blue (TB) raises environmental and health concerns due to its potential teratogenic effects. To avoid this chemical hazard, it is of importance to introduce an alternative non-hazardous vital dye that is compatible with automated cell counters. Erythrosin B (EB) is a vital dye that is impermeable to biological membranes and is used as a food

Salmosin is a novel disintegrin containing the Arg-Gly-Asp sequence that significantly inhibits platelet aggregation, basic fibroblast growth factor-induced endothelial cell proliferation, and tumor progression by antagonizing integrin-mediated cell interactions. Previously, it was shown that daily administration of salmosin was able to inhibit tumor-derived angiogenesis and adherence and proliferation of tumor cells, resulting in suppression of tumor progression. However, it is very difficult t

This study demonstrates that single parents have poorer mental health than partnered parents. Although lower SES is an important factor explaining poorer mental health in single parents, there are other factors we cannot explain about their poor mental health. Therefore, we should pay proper regard to identifying other factors affecting mental health and to establishing policies to support single parents.

Manganese (Mn(2+)) is a trace element that is essential for normal physiology, and is predominantly obtained from food. Several lines of evidence, however, demonstrated that overexposure to MnCl2 exerts serious neurotoxicity, immunotoxicity and developmental toxicity, particularly in male. The present study aimed to evaluate the effect of 0, 1.0, 3.3, and 10 mg/kg/day doses of MnCl2 on the reproductive organs in the immature female rats. Rats (PND 22; S.D. strain) were exposed to MnCl2 (MnCl2 ∙

Recently, salmosin, a novel snake venom-derived disintegrin containing the Arg-Gly-Asp (RGD) sequence, was reported to be both antiangiogenic and antitumorigenic. The antitumor activity was substantiated by in vivo administration of recombinant salmosin into mice bearing tumors. However, it was difficult to prepare functionally active recombinant salmosin and to maintain a therapeutically effective concentration of the protein in the circulatory system by daily injections. Hence, we have suggest

OBJECTIVE: This study aimed to investigate the association between gut microbiota and depressive symptoms in a large population cohort of Korean adults. METHODS: Overall, 1238 participants were included in the study. Participants were categorized into depressed or non-depressed groups, based on the depressive symptoms reported on the Center for Epidemiologic Studies Rating Scale for Depression, with a cutoff score of 16, and their fecal microbiota was profiled using 16S ribosomal RNA gene sequen

This study compared the prevalence of depressive symptoms and suicidal ideation in individuals living alone compared with those living with others and assessed the contribution of socio-demographic factors and physical health to these differences. We analyzed 2221 individuals living alone and 19,397 individuals living with others aged 20-80 years, drawn from the Korean National Health and Nutrition Examination Survey dataset in South Korea. The study group divided into three subgroups based on a

본 논문은 이사회 구성원의 성별 다양성이 기업 투명성에 영향을 미치는지 실증적으로 검증하는데 목적이 있다. 이를 위해 2013년 유가증권 상장기업 중 금융업에 속하지 않는 647개 기업의자료를 이용하여 이사회 내 여성 임원의 수가 재량적 발생액에 미치는 영향을 분석하였다. 본 연구의 주요 결과는 다음과 같다. 첫째, 여성 임원에 대한 기업의 특성에 따른 영향을 통제하기 위해 Heckman(1979)의 2단계 추정방법을 이용한 결과, 이사회 내 여성 임원의 수와 재량적발생액 사이에는 통계적으로 유의한 관계가 발견되지 않았다. 둘째, 기업지배구조를 고려하기 위해 감사위원회 설치 유무, 사외이사 비율, 기업지배구조 등급을 이용하여 분석한 결과, 지배구조가 강하고 이사회 내 여성 임원의 수가 많을수록 재량적 발생액이 낮아지는 것으로 나타났다. 셋째, 표본을 기업지배구조가 강한 그룹과 약한 그룹으로 나누어 분석한 결과, 기업지배구조가강한 그룹에서는 지배구조의 수준에 상관없이 여성 임원의 수가
