Reactive oxygen species (ROS) production is one of the main mechanisms used to kill microbes during innate immune response. D-lactic acid, which is augmented during acute ruminal acidosis, reduces platelet activating factor (PAF)-induced ROS production and L-selectin shedding in bovine neutrophils in vitro. This study was conducted to investigate whether acute ruminal acidosis induced by acute oligofructose overload in heifers interferes with ROS production and L-selectin shedding in blood... -

Neural circuit remodeling and structural plasticity in the cortex during chronic pain
WoojinKim, SunKwangKim 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 8 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2016, Vol.20 No.1 1 1-8 (8 pages)
Damage in the periphery or spinal cord induces maladaptive plastic changes along the somatosensory nervous system from the periphery to the cortex, often leading to chronic pain. Although the role of neural circuit remodeling and structural synaptic plasticity in the ‘pain matrix’ cortices in chronic pain has been thought as a secondary epiphenomenon to altered nociceptive signaling in the spinal cord, progress in whole brain imaging studies on human patients and animal models has suggested a... -

We demonstrated the sensitivity of optically active single-walled carbon nanotubes (SWCNTs) with a diameter below 1 nm that were homogeneously dispersed in cement composites under a mechanical load. Deoxyribonucleic acid (DNA) was selected as the dispersing agent to achieve a homogeneous dispersion of SWCNTs in an aqueous solution, and the dispersion state of the SWCNTs were characterized using various optical tools. It was found that the addition of a large amount of DNA prohibited the... -

Carbon micropatterns (CMs) were fabricated from a negative-type SU-8 photoresist by proton ion beam lithography and pyrolysis. Well-defined negative-type SU-8 micropatterns were formed by proton ion beam lithography at the optimized fluence of 1×1015 ions cm?2 and then pyrolyzed to form CMs. The crosslinked network structures formed by proton irradiation were converted to pseudo-graphitic structures by pyrolysis. The fabricated CMs showed a good electrical conductivity of 1.58×102 S cm?1 and a... -

In recent decades, there has been an increasing interest in the use of carbon fiber reinforced plastic (CFRP) in aerospace, renewable energy and other industries, due to its low weight and relatively good mechanical properties compared with traditional metals. However, due to the high cost of petroleum-based precursors and their associated processing costs, CF remains a specialty product and as such has been limited to use in high-end aerospace, sporting goods, automotive, and specialist... -

한반도의 329개 지진자료에 대하여 S파 감쇠상수의 고유치 분리를 Multiple Lapse Time Window Method(MLTW)법으로 수행하였다. 균일한 속도구조에서 고유감쇠 $Q_i^{-1}$ 값은 S파 직접파와 코다파의 진폭을 감쇠시키고, 산란감 쇠 $Q_s^{-1}$ 값은 S파 직접파는 감쇠시키는 반면 코다파는 증폭시킨다. MLTW법은 해석적인 방법으로 이론곡선을 구하여 관 측값과 최소제곱오차를 이루는 고유 및 산란감쇠를 구하는 방법이다. 지금까지 한반도와 같은 지진 안정지대에서의 MLTW 법 적용연구는 행하여진 바 없는데, MLTW법에 의한 한반도의... -
