in soils planted with tomatoes. For this, the soils were irrigated with five metal concentrations ([1, 1/4, 1/4, 1/4, and 0] × maximum concentrations [MC] detected in irrigation waters near abandoned mine sites) for 18 weeks. Heavy metal concentrations were significantly increased in soils irrigated with MC of heavy metals, among which As and Cu exceeded the maximum heavy metal residue contents of soil approved in Korea. In no heavy metal treatment controls, nematode abundances for all... -

be the primary hazardous heavy metal in CS. The toxicity of As might be enhanced at low pH in CS because exchangeable forms of some heavy metals increase with the decrease of soil pH. The heavy metals, especially As, may have contributed to increasing EC and decreasing av. P2O5. Therefore, the effects of mine drainage contamination from the abandoned mine were derived primarily from contamination by heavy metals such as As. These may have been enhanced in toxicity (solubility) by the lowered pH,... -

Staining profiles and bacterial morphology were compared in Xanthomonas citri pv. citri by a transmission electron microscopy. Four types of negative staining regimes were employed depending on culture media and heavy metal stains. The bacterial cells grown on LB agar media often appeared clustered on the supporting film. Meanwhile, individual bacterial cells could be readily found on the preparations from LB broth media. Typical rod-shaped cells (ca. 1 μm in length) and their flagella were... -

(0 to 1,000 mg/kg) ranged from 68.34 to 95.49% (CV; 4.10 to 13.38%). DON in a buffer solution (250, 500 and 1,000 ng/mL) was isolated using 300 μg of NVRQS-DON and 3 mg of magnetic nanoparticles (MNPs). The mean recovery rates of DON using this mAb-MNP system were 75.2, 96.9, and 88.1% in a buffer solution spiked with DON (250, 500, and 1,000 ng/mL). Conclusively we developed competitive ELISAs for detecting DON in animal feed and created a new tool for DON extraction using mAb-coupled MNPs. -

In this study, we developed a novel tool for purifying two mycotoxins, aflatoxin B1 (AFB1) and zearalenone (ZEN), in feed. This system utilized monoclonal antibodies (mAbs) against AFB1 and ZEN, and magnetic nanoparticles (MNPs). Among ten MNPs with different diameters and functional groups, a 100-nm diameter MNP (fMA) conjugated to an amine group (-NH2) was found to be optimum for coupling with mAbs. The optimal mAb concentrations for coupling to the fMA along with mycotoxin purification... -

caspase-3-like cysteine protease activation in MC3T3E1 osteoblasts. Concomitant treatment of antioxidant; N-acetyl-L-cysteine (NAC), reduced-form glutathione (GSH), or superoxide dismutase (SOD), prevented apoptosis induced by each of the transition metal ions. Catalase or dimethylsulfoxide (DMSO) has less potent inhibitory effect on the apoptosis, compared with NAC, GSH or SOD. In line with the results, nitroblue tetrazolium (NBT) stain shows that each of the transition metals is a potent sourc... -

Cleft palate and alveolus patients require long periods of treatment from birth to adulthood by specialists in various fields. Patients with cleft palate & alveolus frequently have missing teeth, particularly often including the lateral incisor. Orthodontic treatment aims to close this frontal gap by moving the posterior teeth forward after bone grafting of the alveolar cleft. But in patients who are missing more than one tooth, successful treatment by only orthodontics is often very difficult... -

Since salicylic acid (SA) was discovered as an elicitor of tobacco plants inducing the resistance against Tobacco mosaic virus (TMV) in 1979, increasing reports suggest that SA indeed is a key plant hormone regulating plant immunity. In addition, recent studies indicate that SA can regulate many different responses, such as tolerance to abiotic stress, plant growth and development, and soil microbiome. In this review, we focused on the recent findings on SA’s effects on resistance to biotic... -

characterize a rice defense related gene named “jasmonic acid inducible pathogenesis-related class 10” (JIOsPR10) to gain an insight into its functional properties. Semi-quantitative RT-PCR analysis showed up-regulation of JIOsPR10 under salt and drought stress conditions. Constitutive over-expression JIOsPR10 in rice promoted shoot and root development in transgenic plants, however, their productivity was unaltered. Further experiments exhibited that the transgenic plants showed... -

한국식물병리학회 The Plant Pathology Journal 2012, 28권 4호 14 446-452 (7 pages)
The effect of heavy metals on seedling growth and pigment levels was studied in Arabidopsis using essential (Cu, Mn, and Zn) and non-essential metals (Pb and Hg). Generally increasing the concentrations of the metals resulted in a gradual decrease in root and shoot lengths, a decrease in chlorophylls, an increase in anthocyanins and a fluctuation in carotenoid content depending on the metal types. The toxicity of the metals decreased in the following order: Cu > Hg > Pb > Zn > Mn. Among the five... -

is further enhanced in the case of high relative humidity (RH) and in the presence of NH3. The reaction on Al2O3 under different gas concentration ratios is compared, and it is identified that SO2 and NO2 concentrations make an effect on aerosol production. The heterogeneous reactions of SO2 and NO2 on various coal ash are different. The order of reactivity of the three coal ashes is WH>MHU>Centennial. The secondary particulate matter formed on coal ash is higher than that on single metal oxide. -

as heavy metal ions are present in the wastewater produced by various industries. This wastewater flows into rivers, pollutes water supplies, and can contaminate the drinking water supplied to people [1-3]. Powder or activated carbons are being widely used today to mitigate polluted water from industrial sources and contaminated supplies. To make up for the limitations of such materials, there has been strong interest in the use of activated carbon fibers (ACFs) as adsorbents, because they offer... -

volume reduction of 93% and a pollutant reduction efficiency of approximately 99%, 93% and 95% was observed for particulates, nutrients and heavy metals, respectively. While when the system is connected in a combined series-parallel, the volume and average pollutant reduction efficiency for the TSS, nutrients and heavy metals are 65%, 94%, 80% and 85%, respectively. Moreover, the component arrangement in the order of sedimentation tank, infiltration tank and plant bed exhibited a high pollutant... -

본 연구는 도시 강우유출수 처리를 위한 하이브리드 빗물정원 시스템을 개발하고자 수행되었으며, Pilot scale 모니터 링을 통하여 시스템 내의 서로 다른 구성요소간의 효율을 검증하였다. 유입수는 국내·외 도로강우유출수의 농도를 고 려한 인공강우유출수를 이용하여 수행하였다. 모니터링 결과 하이브리드 빗물정원은 시설 내 저류 80%, 지하수의 침 투 15%로 유입수의 약 95% 저감되는 것으로 나타났다. 이는 ST의 저류 및 PB와 IT의 침투 기작이 물순환 효과에 기 여한 것으로 판단된다. 또한 오염물질 저감효율을 산정한 결과,... -

sedimentation efficiency than those with an inclined angle. When vertical baffles were installed in the sedimentation basin of a hybrid constructed wetland to reduce non-point source pollutants in urban areas, the average flow velocity within the basin decreased by 10~30%, while the sedimentation efficiency improved by 1.3~1.5 times. The application of CFD to constructed wetlands is expected to improve the cost efficiency of designing hybrid constructed wetlands with high removal efficiency.
