임프란트 실패의 중요한 원인인 임프란트 주위염은 크게 교합력, 치태세균이나 치석의 축적 등과 같은 국 소적 요인과 전신질환이나 신체방어력의 약화 등과 같은 전신적 요인에 의해 단독적 또는 복합적으로 발 생된다. 임프란트 주위염은 임프란트 주위 치은의 염 증을 동반한 임프란트 주위골의 임상적, 방사선적인 상실을 가지는 임상적인 증상의 표현이다. -
Impact of a Recombinant Biocontrol Bacterium, Pseudomonas fluorescens pc78, on Microbial Community in Tomato Rhizosphere
한국식물병리학회 The Plant Pathology Journal 9 Pages
한국식물병리학회 The Plant Pathology Journal 2016, 32권 2호 7 136-144 (9 pages)
Pseudomonas fluorescens pc78 is an effective biocontrol agent for soil-borne fungal diseases. We previously constructed a P43-gfp tagged biocontrol bacteria P. fluorescens pc78-48 to investigate bacterial traits in natural ecosystem and the environmental risk of genetically modified biocontrol bacteria in tomato rhizosphere. Fluctuation of culturable bacteria profile, microbial community structure, and potential horizontal gene transfer was investigated over time after the bacteria treatment to... -
Phyllosticta musarum Infection-Induced Defences Suppress Anthracnose Disease Caused by Colletotrichum musae in Banana Fruits cv Embul

to have a direct suppressive effect on C. musae as conidia of C. musae germinate on both freckled and non-freckled fruit forming quiescent infections. Our investigations have shown that P. musarum infection induced several defence responses in fruit including the accumulation of five phytoalexins, upregulation of chitinase and β-1,3-glucanase, phenylalanine ammonia lyase (PAL) activity and cell wall lignification. 1H and 13C NMR spectral data of one purified phytoalexin compared closely with... -

한국탄소학회 Carbon Letters 2017, Vol.21 8 68-73 (6 pages)
We have demonstrated the production of thin films containing multilayer graphene-coated copper nanoparticles (MGCNs) by a commercial electrodeposition method. The MGCNs were produced by electrical wire explosion, an easily applied technique for creating hybrid metal nanoparticles. The nanoparticles had average diameters of 10?120 nm and quasispherical morphologies. We made a complex-electrodeposited copper thin film (CETF) with a thickness of 4.8 μm by adding 300 ppm MGCNs to the electrolyte... -

As a replacement for activated carbon, biochar was synthesized and used for the adsorptive removal of formaldehyde and nitrogen oxide. Biochar was produced from the fast pyrolysis of the red marine macro alga, Pyropia tenera. The P. tenera char was then activated with steam, ammonia and KOH to alter its characteristics. The adsorption of formaldehyde, which is one of the main indoor air pollutants, onto the seaweed char was performed using 1-ppm formaldehyde and the char was activated using a... -

Carbon rich fly ash was recently reported to have compositions that are ideal for use as a precursor and catalyst for carbon nanotube growth. This fly ash powder is mostly composed of pure carbon, predominantly present as sp2. In this work, the effect of sonication time on the morphology and structural properties of carbon rich fly ash particles is reported. The obtained results show that ultrasound treatment is an effective tool for producing ultrafine particles/fragments with higher porosity,... -

Gas transport through graphene-derived membranes has gained much interest recently due to its promising potential in filtration and separation applications. In this work, we explore Kr-85 gas radionuclide sequestration from natural air in nanoporous graphene oxide membranes in which different sizes and geometries of pores were modeled on the graphene oxide sheet. This was done using atomistic simulations considering mean-squared displacement, diffusion coefficient, number of crossed species of... -

Aikifa Raza, Jiaqi Wang, Shan Yang, Yang Si, Bin Ding 한국탄소학회 Carbon Letters 14 Pages
한국탄소학회 Carbon Letters 2014, Vol.15 No.1 1 1-14 (14 pages)
Carbon nanofibers (CNFs) with diameters in the submicron and nanometer range exhibit high specific surface area, hierarchically porous structure, flexibility, and super strength which allow them to be used in the electrode materials of energy storage devices, and as hybrid-type filler in carbon fiber reinforced plastics and bone tissue scaffold. Unlike catalytic synthesis and other methods, electrospinning of various polymeric precursors followed by stabilization and carbonization has become a... -

The purpose of this study was to provide a basis for studying the molecular mechanism of pharmacological action of chlorhexidine digluconate. Large unilamellar vesicles (OPGTL) were prepared with total lipids extracted from cultured Porphyromonas gingivalis outer membranes (OPG). The anthroyloxy probes were located at a graded series of depths inside a membrane, depending on its substitution position (n) in the aliphatic chain. Fluorescence polarization of n-(9-anthroyloxy)stearic acid was used... -

Phospholamban은 심근 근장그물 Ca2+-ATPase 조절단백이다. 조절작용기전은 탈인산화된 phospholamban에 의해 Ca2+-ATPase가 억제됨으로 나타나며, 이 phospholamban이 인산화됨으로 Ca2+-ATPase에 대한 억제가 반전됨을 보인다. 최근에 phospholamban의 cytoplasmic domain만으로 Ca2+-ATPase를 억제하기에는 불충분하다는 보고가 있어 본 실험을 계획하였다. Ca2+-ATPase의 활성을 억제하는 phospholamban domain을 밝히기 위하여 합성한 phospholamban 펩타이드(아미노산 1-25)의 Ca2+ uptake에 대한 효과를 살펴보았다. 골격근... -

한국탄소학회 Carbon Letters 2016, Vol.20 11 72-75 (4 pages)
The repair of mortar-based structures is critically important because mortar-based structures such as buildings, bridges, tunnels, highway and roads are inevitably degraded by deterioration or damage. To save expense during construction and to avoid traffic congestion during repair work, it is very important to reduce construction time as much as possible. In order to reduce construction time, therefore, the setting time of mortars has to be shortened. The mortars which have short setting times... -

Kap Seung Yang, Bo-Hye Kim, Seong-Ho Yoon 한국탄소학회 Carbon Letters 9 Pages
한국탄소학회 Carbon Letters 2014, Vol.15 No.3 2 162-170 (9 pages)
Pitch is an attractive raw material for carbon fiber precursors due to its low cost stemming from its availability as a residue of coking and petroleum processes. Ford Motor Company reported a carbon fiber target price of $11.0/kg by using a fast cycle-time manufacturing method with carbon fiber in an inexpensive format, allowing for an average retail price of gasoline of $3.58/gallon. They also recommended the use of carbon fiber with strength of 1700 MPa, modulus of 170 GPa, and 1.5%...
