Double-walled carbon nanotubes: synthesis, structural characterization, and application
Yoong Ahm Kim, Kap-Seung Yang, Hiroyuki Muramatsu, Takuya Hayashi, Morinobu Endo, Mauricio Terrones, Mildred S. Dresselhaus 한국탄소학회 Carbon Letters 12 Pages
한국탄소학회 Carbon Letters 2014, Vol.15 No.2 4 77-88 (12 pages)
Double walled carbon nanotubes (DWCNTs) are considered an ideal model for studying the coupling interactions between different concentric shells in multi-walled CNTs. Due to their intrinsic coaxial structures they are mechanically, thermally, and structurally more stable than single walled CNTs. Geometrically, owing to the buffer-like function of the outer tubes in DWCNTs, the inner tubes exhibit exciting transport and optical properties that lend them promise in the fabrication of field-effect... -

Effects of CoCl2 on multi-lineage differentiation of C3H/10T1/2 mesenchymal stem cells
HongIlYoo, YeonHeeMoon, MinSeokKim 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 10 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2016, Vol.20 No.1 7 53-62 (10 pages)
Mesenchymal stem cells (MSCs) in the bone marrow and other somatic tissues reside in an environment with relative low oxygen tension. Cobalt chloride (CoCl2) can mimic hypoxic conditions through transcriptional changes of some genes including hypoxia-inducible factor-1a (HIF-1a) and vascular endothelial growth factor (VEGF). This study evaluated the potential role of CoCl2 preconditioning on multi-lineage differentiation of C3H/10T1/2, a murine MSC line to understand its possible molecular... -

대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2014, Vol.18 No.2 6 129-134 (6 pages)
It has been suggested that transition metal ions such as iron can produce an oxidative injuries to nigrostriatal dopaminergic neurons, like Parkinson’s disease (PD) and subsequent compensative increase of tetrahydrobiopterin (BH4) during the disease progression induces the aggravation of dopaminergic neurodegeneration in striatum. It had been established that the direct administration of BH4 into neuron would induce the neuronal toxicity in vitro. To elucidate a role of BH4 in patho-genesis in... -
Gene Expression Profile in Microglia following Ischemia- Reperfusion Injury
JuHyeonOh, HyungSooHan, JaeSikPark 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 8 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2006, Vol.10 No.4 2 173-180 (8 pages)
Microglial activation is thought to play a role in the pathogenesis of many brain disorders. Therefore, understanding the response of microglia to noxious stimuli may provide insights into their role in disorders such as stroke and neurodegeneration. Many genes involved in this response have been identified individually, but not systematically. In this regards, the microarray system permitted to screen a large number of genes in biological or pathological processes. Therefore, we used microarray... -

한국식물병리학회 The Plant Pathology Journal 2010, 26권 1호 13 90-92 (3 pages)
Staining profiles and bacterial morphology were compared in Xanthomonas citri pv. citri by a transmission electron microscopy. Four types of negative staining regimes were employed depending on culture media and heavy metal stains. The bacterial cells grown on LB agar media often appeared clustered on the supporting film. Meanwhile, individual bacterial cells could be readily found on the preparations from LB broth media. Typical rod-shaped cells (ca. 1 μm in length) and their flagella were... -

한국탄소학회 Carbon Letters 2017, Vol.24 12 90-96 (7 pages)
of DNA with respect to the cement was found to be 0.05 wt%. The strong Raman signals coming from the SWCNTs entrapped in the cement composites enabled us to understand their dispersion state within the cement as well as their interfacial interaction. The G and G’ bands of the SWCNTs sensitively varied under mechanical compression. Our results indicate that an extremely small amount of SWCNTs can be used as an optical strain sensor if they are homogeneously dispersed within cement composites. -

Cadmium (Cd) is a well-known hepatotoxic environmental pollutant. We used rat hepatocytes as a model to study oxidative damage induced by Cd, effects on the antioxidant systems, and the role of N-acetylcysteine (NAC) in protecting cells against Cd toxicity. Hepatocytes were incubated for 12 and 24 h with Cd (2.5, 5, 10 μM). Results showed that Cd can induce cytotoxicity: 10 μM resulted in 36.2% mortality after 12 h and 47.8% after 24 h. Lactate dehydrogenase, aspartate... -

Quercetin mainly exists in the skin of colored fruits and vegetables as one of flavonoids. Recent studies show that quercetin, like other flavonoids, has diverse pharmacological actions. However, relatively little is known about quercetin effects in the regulations of ligand-gated ion channels. In the previous reports, we have shown that quercetin regulates subsets of homomeric ligand-gated ion channels such as glycine, 5-HT3A and Ձ7 nicotinic acetylcholine receptors. In the present study,... -

Many therapeutic roles have been proposed for sigma-1 receptor (Sig-1R), but the involvement of Sig-1R in neuropathic pain has currently not been well explored. The present study aimed to evaluate the anti-nociceptive effect of Sig-1R antagonist (BD1047) in a rat model of chronic compression of the dorsal root ganglion (CCD), which is a model of human foraminal stenosis and radicular pain. When stainless steel rods were inserted into the intervertebral foramen of lumbar vertebrae 4 and 5, the... -

The protective effects of baicalein, one of the flavonoids in Scutellaria baicalensis Georgi, were evaluated against 6-hydroxydopamine (6-OHDA)-induced neuronal damage in mice and cultured human neuroblastoma cells. Nigrostriatal damage was induced by stereotaxically injecting 6-OHDA into the right striatum. Baicalein was administered intraperitoneally 30 min before and 90 min after lesion induction. Animals received a further daily injection of baicalein for 3 consecutive days. Two weeks after... -

The reactive intermediates formed during the metabolism of therapeutic agents, toxicants and carcinogens by cytochromes P450 are frequently capable of covalently binding to tissue macromolecules and causing tissue damage. It has been shown that YH439, a congener of malotilate, is effective in suppressing hepatic P450 2E1 expression. The present study was designed to further establish the mechanistic basis of YH439 protection against toxicant by assessing its effects against chemical-mediated... -
A Cultural-Historical View of Child Development: Key Concepts for Going Beyond a Universal View of the Child
Marilyn Fleer 환태평양유아교육연구학회 Asia-Pacific journal of research in early childhood education 19 Pages
환태평양유아교육연구학회 Asia-Pacific journal of research in early childhood education 2015, Vol.9 No.1 2 19-37 (19 pages)
A developmental view of child development with its biological imperatives has been extensively critiqued over the years and found to be wanting from a range of cultural (Rogoff, 2003; Howes, 2010), social (Qvortrup, Corsaro & Honig, 2009) and even health (Bendelow, 2009; Rogoff, 2011) reasons. But what has been missing from these debates has been a theoretically robust presentation of another way of conceptualizing children’s development (Hedegaard & Fleer, 2013). In drawing upon... -

Chitosan has been considered an environmental-friend- ly polymer. However, its use in agriculture has not been extended yet due to its relatively low solubility in water. N-Methylene phosphonic chitosan (NMPC) is a water- soluble derivative prepared by adding a phosphonic group to chitosan. This study demonstrates that NMPC has a fungicidal effect on the phytopathogenic fungus Fusarium solani f. sp. eumartii (F. eumartii) judged by the inhibition of F. eumartti mycelial growth and spore... -
Overlook of current chemical vapor deposition-grown large single-crystal graphene domains
Kyung Tae Park, Taehoon Kim, Chong Rae Park 한국탄소학회 Carbon Letters 11 Pages
한국탄소학회 Carbon Letters 2014, Vol.15 No.3 1 151-161 (11 pages)
Exceptional progress has been made with chemical vapor deposition (CVD) of graphene in the past few years. Not only has good monolayer growth of graphene been achieved, but large-area synthesis of graphene sheets has been successful too. However, the polycrystalline nature of CVD graphene is hampering further progress as graphene property degrades due to presence of grain boundaries. This review will cover factors that affect nucleation of graphene and how other scientists sought to obtain large...
