percolation thresholds (at 0.8 vol%) and higher electrical conductivity values than those of samples extruded by capillary and injection molding. Shear induced orientation of MWCNT was observed via scanning electron microscopy, in the direction of flow in a PC matrix during the extrusion process. The surface resistivity rose with increasing shear rate, because of the breakdown of the network junctions between MWCNTs. For real applications such as injection molding and the extrusion process, the... -

Chronic Ca2+ influx through voltage-dependent Ca2+ channels enhance delayed rectifier K+ currents via activating Src family tyrosine kinase in rat hippocampal neurons
Yoon-SilYang, Sang-ChanJeon, Dong-KwanKim, Su-YongEun, Sung-CherlJung 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 7 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2017, Vol.21 No.2 14 259-265 (7 pages)
Excessive influx and the subsequent rapid cytosolic elevation of Ca2+ in neurons is the major cause to induce hyperexcitability and irreversible cell damage although it is an essential ion for cellular signalings. Therefore, most neurons exhibit several cellular mechanisms to homeostatically regulate cytosolic Ca2+ level in normal as well as pathological conditions. Delayed rectifier K+ channels (IDR channels) play a role to suppress membrane excitability by inducing K+ outflow in various... -

We investigated the question of whether cholesterol catabolite can influence expression of inflammatory cytokines via Toll-like receptors (TLR) in monocytic cells. Treatment of THP-1 monocytic cells with 27-hydroxycholesterol (27OHChol) resulted in induction of gene transcription of TLR6 and elevated level of cell surface TLR6. Addition of FSL-1, a TLR6 agonist, to 27OHChol-treated cells resulted in transcription of the IL-1α gene and enhanced secretion of the corresponding gene product.... -

Understanding the cellular and molecular mechanisms involved in the development and progression of pulmonary hypertension (PH) remains imperative if we are to successfully improve the quality of life and life span of patients with the disease. A whole plethora of mechanisms are associated with the development and progression of PH. Such complexity makes it difficult to isolate one particular pathway to target clinically. Changes in intracellular free calcium concentration, the most common... -
Oxygen/Glucose Deprivation and Reperfusion Cause Modifications of Postsynaptic Morphology and Activity in the CA3 Area of Organotypic Hippocampal Slice Cultures
YeonJooJung, EunChengSuh, KyungEunLee 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 7 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2012, Vol.16 No.6 8 423-429 (7 pages)
Brain ischemia leads to overstimulation of N-methyl-D-aspartate (NMDA) receptors, referred as excitotoxicity, which mediates neuronal cell death. However, less attention has been paid to changes in synaptic activity and morphology that could have an important impact on cell function and survival following ischemic insult. In this study, we investigated the effects of reperfusion after oxygen/glucose deprivation (OGD) not only upon neuronal cell death, but also on ultrastructural and biochemical... -

group were also significantly different (p = 0.0084, t = 3.271, df = 10). Cresyl violet staining indicated significant loss of CA1 cells at post-ischemic day 7. Overall, we showed post-ischemic time-dependent, differential changes of three characteristics, including spontaneous activity, network relationship and excitability of CA1 cells, suggesting sustained neural functions. Thus, histological observation of CA1 cell death till post-ischemic day 7 may not represent actual neuronal death. -
Neurovascular Mechanisms in Stroke, Neurodegeneration and Recovery
EngH.Lo 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 8 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2006, Vol.10 No.5 1 223-230 (8 pages)
The emerging concept of the“neurovascular unit”may enable a powerful paradigm shift for neuroscience. Instead of a pure focus on the“neurobiology”of disease, an opportunity now exists to return to a more integrative approach. The neurovascular unit emphasizes that signaling between vascular and neuronal compartments comprise the basis for both function and dysfunction in brain. Hence, brain disorders are not just due to death of neurons, but instead manifested as cell signaling perturbations... -

only (I-RCA), verapamil infusion (VI-RCA) and nifedipine infusion (NI-RCA) group, respectively. The ischemia did not affect hemodynamics, mean arterial pressure, heart rate, LVdP/dtmax, and decreased RCA flow. Arterial pressure and heart rate during ischemia-reperfusion were decreased in VI-RCA and NI-RCA, and RCA flow during reperfusion was increased in NI-RCA. 5-Hydroxytryptamine (5-HT) produced concentration- dependent contractions in C-RCA. The 5-HT-induced contractions were potentiated in... -

정신 질환은 수세기 동안 영혼 혹은 마음의 병으로 이해되었다. 마음의 본질을 밝히려는 노력들이 계속되었다. 지난 세기, 정신 질환들이 뇌의 질병으로 인지되기 시작했고, 실제 뇌의 이상들이 많이 밝혀졌다. 이제 21세 기를 앞둔 현 시점에서 향후 정신의학의 혁신과 발달을 위해서도 뇌와 마음의 연결에 대한 이해는 필수적이 다. 마음의 본질을 알기 위해서는 뇌의 본질에 대해서도 알아야 한다. 뇌를 알수록 마음과 정신 질환에 대한 진실이 밝혀질 것이다

Likewise, AMOVA indicated that fungus population has behaved as a large population with- out structuring by geographical origin and sampling years (FST = 0.00180, P = 0.20053 and FST = 0.00241, P = 0.19693, respectively). Additionally, the haplotype network based on intraspecific phylogenetic analysis of H. vastatrix using Peruvian and NCBI sequences revealed that Peruvian ancestral haplotypes, which were maintained in time and space, would correspond to the reported sequences of the races II an... -
Actin Cytoskeleton and Golgi Involvement in Barley stripe mosaic virus Movement and Cell Wall Localization of Triple Gene Block Proteins
한국식물병리학회 The Plant Pathology Journal 14 Pages

Barley stripe mosaic virus (BSMV) induces massive actin filament thickening at the infection front of infected Nicotiana benthamiana leaves. To determine the mechanisms leading to actin remodeling, fluorescent protein fusions of the BSMV triple gene block (TGB) proteins were coexpressed in cells with the actin marker DsRed: Talin. TGB ectopic expression experiments revealed that TGB3 is a major elicitor of filament thickening, that TGB2 resulted in formation of intermediate DsRed:Talin... -

구조화 이론에 따르면 구조와 행위자는 상호의존적 관계 안에 존재하며, 이 구조들은 인간의 행동을 제약하기도 하고 촉진하기도 한다. 구조화 이론을 건강 불평등 문제에 접목시켰을 때, 우리는 커뮤니케이션 인프라가 국가적 보건 측면에서 제약적인, 그리고 촉진적인 역할을 수행할 것임을 추정해 볼 수 있다. 본 연구는 국가의 정보통신망이 유아, 아동 사망률에 미치는 장기적 영향을 측정하기 위해 인구 천 명당 전화회선의 평균 숫자를 변수로 사용했다. 세계개발 지수를 이용해 202개 국가를 대상으로 종단적 회귀분석을 적용해... -
