Butylated hydroxyanisole (BHA) is a synthetic phenolic compound consisting of a mixture of two isomeric organic compounds: 2-tert-butyl-4-hydroxyanisole and 3-tert-butyl-4-hydroxyanisole. We examined the effect of BHA against hydrogen peroxide (H2O2)-induced apoptosis in primary cultured mouse hepatocytes. Cell viability was significantly decreased by H2O2 in a dose-dependent manner. Additionally, H2O2 treatment increased Bax, decreased... -

To learn the developmental changes in intrinsic electrophysiological properties of the second order taste neurons, whole cell recordings from the developing nucleus of the solitary tract neurons were done in brainstem slices of postnatal rats. Rats aged from postnatal 0 to 21 days (P0-P21) were used, being divided into 3 age groups: postnatal first week (P0-P7 days), second week (P8-P14 days), and third week (P15-P21 days). Slices containing gustatory NTS were cut horizontally in the thickness... -
Effect of Acibenzolar-S-methyl and Rahnella aquatilis (Ra39) on Chitinase and β-1, 3-glucanase Activities and Disease Resistance of Apple Plants
한국식물병리학회 The Plant Pathology Journal 7 Pages
한국식물병리학회 The Plant Pathology Journal 2010, 26권 1호 9 63-69 (7 pages)
The effect of Acibenzolar-S-methyl (ASM) and Rahnella aquatilis Ra39 against apple fire blight disease caused by Erwinia amylovora were tested as a possible alternative to streptomycin. In vitro studies, no inhibition effect against the pathogen was found when ASM was tested. Under greenhouse conditions, application of R. aquatilis Ra39 with the highly susceptible M26 rootstock resulted in a marked disease suppression. Application of ASM and strain Ra39 caused a high decrease of the disease, 82%... -

Towards a Reflexive Pedagogy in Early Childhood Education: Interweaving the Project Approach and the Reggio Emilia Approach
Pei-Wen Tzuo, Der-Thanq Chen 환태평양유아교육연구학회 Asia-Pacific journal of research in early childhood education 15 Pages
환태평양유아교육연구학회 Asia-Pacific journal of research in early childhood education 2012, Vol.6 No.2 4 69-83 (15 pages)
This paper discusses differences between two popular curriculum approaches in early childhood education: the Project Approach developed in the United States and the Reggio Emilia Approach developed in Italy. Although they are similar in many ways, their differences are mainly due to their divergence in focus on domains of learning: one on science and social science, the other on art. In turn, differences in epistemology, ontology, the purpose of education, the learning process, and types of... -
영국의 민간경비 의무적 자격증 및 인증계약자 제도에 관한 연구
이성기, 김학경 한국경호경비학회 시큐리티연구 31 Pages

세계적으로 민간경비산업은 경제발전과 비례하여 성장해 왔다. 기존의 국가기관에 의한 치안서비스로는 다양한 경제주체와 국민들의 보다 질 좋은 경비서비스에 대한 욕구를 충족 해주지 못하였기 때문이다. 따라서 현대의 민간경비업체에 의한 치안서비스는, 기본적으로 시장의 원리에 의한 자율경쟁 하에서 제공되는 서비스의 질과 가격, 그리고 고객의 수요에 따라 결정된다고 할 수 있다. 그렇지만 경비서비스의 공공재적 성격상 국가가 해당 경비업 체의 자격과 서비스 질을 평가하고 관리하는 세련된 관리시스템도 필수적이다.... -

국보 1호인 숭례문 화재는 화재조사자뿐만 아니라 국민들에게 크나큰 아픔을 안겨 주었다. 이 연구의 목적은 현장조사를 통하여 목조 문화재 화재 시 생성되는 연소패턴과 목재 마루바닥에 인화성 물질을 살포 후 착화하였을 때 나타나는 촉진제에 의한 연소 흔적 등을 확인하는데 있다. 또한 이 연구결과는 유사한 화재 발생 시 화재조사요원에게 정확한 화재 원인을 감식할 수 있는 자료가 될 것이다. -
Characterization of Ionic Currents in Human Neural Stem Cells

대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2008, Vol.12 No.4 1 131-136 (6 pages)
The profile of membrane currents was investigated in differentiated neuronal cells derived from human neural stem cells (hNSCs) that were obtained from aborted fetal cortex. Whole-cell voltage clamp recording revealed at least 4 different currents: a tetrodotoxin (TTX)-sensitive Na+ current, a hyperpolarization-activated inward current, and A-type and delayed rectifier-type K+ outward currents. Both types of K+ outward currents were blocked by either 5 mM tetraethylammonium (TEA) or 5 mM... -

Several signal transduction pathways have been implicated in ischemic preconditioning induced by the activation of ATP-sensitive K (KATP) channels. We examined whether protein kinase C (PKC) modulated the activity of KATP channels by recording KATP channel currents in rabbit ventricular myocytes using patch-clamp technique and found that phorbol 12,13-didecanoate (PDD) enhanced pinacidil-induced KATP channel activity in the cell-attached configuration; and this effect was prevented by... -

We examined the effects of EGTA and verapamil on phorbol ester-and forskolin-stimulated LH releases and LHβ subunit mRNA levels in order to verify the role of extracellular Ca++ on PKC- or cAMP-induced increases in LH release and LHβ subunit mRNA levels in cultured anterior pituitary cells of rat. Forskolin-stimulated LHβ subunit mRNA levels as well as LH release were all suppressed by prevention of Ca++ mobilization from extracellular environment, after the treatment of EGTA as a Ca++... -
