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... -

Carbon fibers (CFs) have a unique combination of properties which allow them to be widely used as reinforcing materials in advanced polymer composites. The mechanical properties of CF-reinforced polymer composites are governed mainly by the quality of interfacial adhesion between the CFs and the polymer matrix. Surface treatments of CFs are generally carried out to introduce chemical functional groups on the fiber surfaces, which provide the ability to control the surface characteristics of CFs.... -

a significant reduction in binding of the variable region of LigB to Fn using small interfering RNA (siRNA). Finally, the isothermal titration calorimetric results confirmed the interaction between the variable region of LigB and Fn. This is the first report to demonstrate that LigB binds to MDCK cells. In addition, the reduction of Fn expression in the MDCK cells, by siRNA, reduced the binding of LigB. Taken together, the data from the present study showed that LigB is a Fn-binding protein of... -

Osteopontin (OPN) is a secretory protein that plays an important role in urinary stone formation. Hydration status is associated with the development of urolithiasis. This study was conducted to examine the effects of dehydration and hydration on OPN expression in the rat kidney. Animals were divided into three groups, control, dehydrated, and hydrated. Kidney tissues were processed for light and electron microscope immunocytochemistry, in situ hybridization, and immunoblot analysis. Dehydration... -
Feasibility of utilizing the patellar ligament angle for assessing cranial cruciate ligament rupture in dogs
Jung-ha Lee, Soon-wuk Jeong 대한수의학회 Journal of Veterinary Science 6 Pages
대한수의학회 Journal of Veterinary Science 2014, 제 15권 제 4호 8 563-568 (6 pages)
The patellar ligament angle (PLA) was assessed in 105 normal stifle joints of 79 dogs and 33 stifle joints of 26 dogs with a ruptured cranial cruciate ligament (CrCL). The PLA of stifles with complete CrCL rupture was significantly lower than that of normal stifles, particularly at a flexion angle of 60∼80o in both plain and stress views. If the PLA was ＜90.55o on the stress view with a 60∼80o flexion angle, the dog was diagnosed with a complete rupture of the CrCL with a sensitivity of 83.9%... -

Mammalian oocyte maturation and early embryo development processes are Ca-dependent. In this study, we used confocal microscopy to investigate the distribution pattern of Ca and its dynamic changes in the processes of bovine oocytes maturation, in vitro fertilization (IVF), parthenogenetic activation (PA) and somatic cell nuclear transfer (SCNT) embryo development. During the germinal vesicle (GV) and GV breakdown stage, Ca was distributed in the cortical ooplasm and throughout the oocytes from... -

본 논문은 송국리유형 발생과 관련된 여러 주장들을 학사적으로 검토하고 가락동 재지기원설을 보완하기 위해 작성되었다. 송국리유형 발생설은 크게 재지기원설과 외래기원설로 구분되며, 재지기원설은 역삼동 재지기원설과 가락동 재지기원설로 세분된다. 그렇지만 이러한 구분과는 달리 기존 연구자들의 주장은 입론과 송국리유형의 계보와 발생 지역, 편년 그리고 소위 ‘선송국리유형’단계의 유물, 유구복합체에 대한 해석과 같이 세부적인 문제에 있어서는 견해 차이가 있다. 즉 동일한 발생설을 공유하고 있음에도 불구하고... -

Remote ischemic preconditioning (RIPC) is an intrinsic phenomenon whereby 3~4 consecutive ischemia-reperfusion cycles to a remote tissue (noncardiac) increases the tolerance of the myocardium to sustained ischemiareperfusion induced injury. Remote ischemic preconditioning induces the local release of chemical mediators which activate the sensory nerve endings to convey signals to the brain. The latter consequently stimulates the efferent nerve endings innervating the myocardium to induce...
