This study was conducted to measure the difference in levels of cerebral metabolites in the right and left hemispheres, gray (GM) and white matter (WM), imaging planes, and anatomical regions of healthy dogs to establish normal variations. Eight male Beagle dogs (1 to 4 years of age; mean age, 2 years) with no evidence of neurologic disease were studied. Using the multi-voxel technique on a 1.5 Tesla magnetic resonance imaging scanner, metabolite values (N-acetyl aspartate [NAA], choline [Cho],... -

Sometimes, spinal cord injury (SCI) results in various chronic neuropathic pain syndromes that occur diffusely below the level of the injury. It has been reported that behavioral signs of neuropathic pain are expressed in the animal models of contusive SCI. However, the observation period is relatively short considering the natural course of pain in human SCI patients. Therefore, this study was undertaken to examine the time course of mechanical and cold allodynia in the hindpaw after a spinal... -

Ampicillin, a Ղ-lactam antibiotic, has been reported to induce astrocytic glutamate transporter-1 which plays a crucial role in protecting neurons against glutamate excitotoxicity. We investigated the effect of ampicillin on neuronal damage in the mouse hippocampus and neostriatum following transient global forebrain ischemia. Male C57BL/6 mice were anesthetized with halothane and subjected to bilateral occlusion of the common carotid artery for 40 min. Ampicillin was administered... -

Young children are increasingly surrounded by a variety of technologies including television, computers, iPads, and mobile phones. This small qualitative study explored how Chinese immigrant families living in Australia viewed their children’s use of technology at home. Six parents and three grandparents representing nine different families with children aged three to six years were interviewed. Data were analysed using Rogoff’s (2003) personal, interpersonal and cultural-institutional planes... -

Na Rae Kim, Hong Joo An, Young Soo Yun, Hyoung-Joon Jin 한국탄소학회 Carbon Letters 5 Pages
한국탄소학회 Carbon Letters 2017, Vol.22 13 110-114 (5 pages)
Lithium-ion batteries (LIBs) have attracted increasing attention as a sustainable power source due to the rapid growth in mobile electronics and electric automobile markets, driven by increasing environmental awareness [1-4]. The electrochemical performance of LIBs is strongly dependent on the active electrode materials. Therefore, their continuing advanced development is of key importance to meet the expectations of the market [5-7]. Graphite, commonly used in LIB anodes, forms binary graphite... -
High-energy-density activated carbon electrode for organic electric-double-layer-capacitor using carbonized petroleum pitch
Poo Reum Choi, Sang-Gil Kim, Ji Chul Jung, Myung-Soo Kim 한국탄소학회 Carbon Letters 11 Pages
한국탄소학회 Carbon Letters 2017, Vol.22 8 70-80 (11 pages)
Activated carbons (ACs) have been used as electrode materials of electric double-layer capacitors (EDLC) due to their high specific surface areas (SSA), stability, and ecological advantages. In order to make high-energy-density ACs for EDLC, petroleum pitch (PP) precarbonized at 500?1000°C in N2 gas for 1 h was used as the electrode material of the EDLC after KOH activation. As the pre-carbonization temperature increased, the SSA, pore volume and gravimetric capacitance tended to decrease, but... -

In this study, we evaluated if the implantation of allogenic adipose-derived stem cells (ASCs) improved neurological function in a canine spinal cord injury model. Eleven adult dogs were assigned to three groups according to treatment after spinal cord injury by epidural balloon compression: C group (no ASCs treatment as control), V group (vehicle treatment with PBS), and ASC group (ASCs treatment). ASCs or vehicle were injected directly into the injured site 1 week after spinal cord injury.... -
Cilostazol Decreases Ethanol-Mediated TNFalpha Expression in RAW264.7 Murine Macrophage and in Liver from Binge Drinking Mice

대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2012, Vol.16 No.2 8 131-138 (8 pages)
Alcoholic hepatitis is a leading cause of liver failure in which the increased production of tumor necrosis factor Ձ (TNFՁ) plays a critical role in progression of alcoholic liver disease. In the present study, we investigated the effects of cilostazol, a selective inhibitor of type III phosphodiesterase on ethanol-mediated TNFՁ production in vitro and in vivo, and the effect of cilostazol was compared with that of pentoxifylline, which is currently used in clinical trial.... -
Modulation of Large Conductance Ca2+-activated K+ Channel of Skin Fibroblast (CRL-1474) by Cyclic Nucleotides

대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2005, Vol.9 No.2 9 131-134 (4 pages)
Potassium channels in human skin fibroblast have been studied as a possible site of Alzheimer disease pathogenesis. Fibroblasts in Alzheimer disease show alterations in signal transduction pathway such as changes in Ca2 homeostasis and/or Ca2-activated kinases, phosphatidylinositol cascade, protein kinase C activity, cAMP levels and absence of specific K channel. However, little is known so far about electrophysiological and pharmacological characteristics of... -

Ethanol이 암세포 증식 속도에 미치는 직접적인 영향 검색의 일환으로 배양된 mouse myeloma cell line Sp2/0-Ag14로부터 분리한 형질막 (Sp2/0-PMV) 유동성에 미치는 ethanol의 영향을 형광분석법으로 측정하였다. 그 결과 ethanol은 Sp2/0-PMV 지질 이중층 측방확산운동의 범위와 속도를 증가시켰고 회전확산운동 범위도 증가시켰다. 특히 ethanol은 Sp2/0-PMV 지질이중층 중 내부단층 (inner monolayer)에 비하여 비교적 선택적으로 외부단층 (outer monolayer)의 회전확산운동 범위를 증가시킨다는 것을 확인하였다.
