Most known osteoporosis medicines are effective for bone resorption, and so there is an increasing demand for medicines that stimulate bone formation. Watercress (N. officinale R. Br.) is widely used as a salad green and herbal remedy. This study analyzed a watercress extract using ultra-performance liquid chromatography/mass spectrometry, and identified a rutin as one of its major constituents. Osteogenic-related assays were used to compare the effects of watercress containing rutin (WCR) and... -
Enterobacter cloacae, an Emerging Plant-Pathogenic Bacterium Affecting Chili Pepper Seedlings
한국식물병리학회 The Plant Pathology Journal 10 Pages
한국식물병리학회 The Plant Pathology Journal 2018, 34권 1호 1 1-10 (10 pages)
A previously unreported bacterial disease on chili pepper (Capsicum annuum L.) seedlings affecting as many as 4% of seedlings was observed in greenhouses in Chihuahua, Mexico (Delicias and Meoqui counties). Initial lesions appeared as irregular small spots on leaves and brown necrosis at margins tips were observed. Later, the spots became necrotic with a chlorotic halo. Advanced disease was associated with defoliation. A Gram negative, rod-shaped bacterium was isolated from diseased chili pepper... -
Identification of Novel Source of Resistance and Differential Response of Allium Genotypes to Purple Blotch Pathogen, Alternaria porri (Ellis) Ciferri
한국식물병리학회 The Plant Pathology Journal 9 Pages
한국식물병리학회 The Plant Pathology Journal 2016, 32권 6호 4 519-527 (9 pages)
Purple blotch, caused by Alternaria porri (Ellis) Cifferi, is a serious disease incurring heavy yield losses in the bulb and seed crop of onion and garlic worldwide. There is an immediate need for identification of effective resistance sources for use in host resistance breeding. A total of 43 Allium genotypes were screened for purple blotch resistance under field conditions. Allium cepa accession ‘CBT-Ac77’ and cultivar ‘Arka Kalyan’ were observed to be highly... -
RT-PCR Detection of Five Quarantine Plant RNA Viruses Belonging to Potyand Tospoviruses
한국식물병리학회 The Plant Pathology Journal 6 Pages
한국식물병리학회 The Plant Pathology Journal 2011, 27권 3호 12 291-296 (6 pages)
In order to detect quarantine plant viruses, we developed reverse transcription-polymerase chain reaction (RT-PCR) primer pairs for five single-stranded (ss) plant RNA viruses that are not currently reported in Korea but could be potential harmful plant viral pathogens. Three viruses such as Chilli veinal mottle virus (ChiVMV), Colombian datura virus (CDV), and Tobacco etch virus (TEV) belong to the genus Potyvirus while Chrysanthemum stem necrosis virus (CSNV) and Iris yellow spot virus (IYSV)... -
Isolation and Identification of Burkholderia pyrrocinia CH-67 to Control Tomato Leaf Mold and Damping-off on Crisphead Lettuce and Tomato
한국식물병리학회 The Plant Pathology Journal 9 Pages
한국식물병리학회 The Plant Pathology Journal 2011, 27권 1호 10 59-67 (9 pages)
A bacterial strain CH-67 which exhibits antagonism towards several plant pathogenic fungi such as Botrytis cinerea, Fulvia fulva, Rhizoctonia solani, Sclerotinia sclerotiorum, Colletotrichum sp. and Phytophthora sp. was isolated from forest soil by a chitin-baiting method. This strain was identified as Burkholderia cepacia complex (Bcc) and belonging to genomovar IX (Burkholderia pyrrocinia) by colony morphology, biochemical traits and molecular method like 16S rRNA and recA gene analysis. This... -
Carbon-allotropes: synthesis methods, applications and future perspectives
P. S. Karthik, A. L. Himaja and Surya Prakash Singh 한국탄소학회 Carbon Letters 19 Pages
한국탄소학회 Carbon Letters 2014, Vol.15 No.4 1 219-237 (19 pages)
The element carbon has been used as a source of energy for the past few hundred years, and now in this era of technology, carbon has played a significant and very prominent role in almost all fields of science and technology. So as an honour to this marvellous element, we humans should know about its various forms of existence. In this review article, we shed light on all possible carbon-allotropes; similarities in their synthesis techniques and the starting materials; their wide range of... -
Carbon nanospheres synthesized via solution combustion method: their application as an anode material and catalyst for hydrogen production

한국탄소학회 Carbon Letters 2014, Vol.15 No.3 7 198-202 (5 pages)
Amorphous agglomerates of carbon nanospheres (CNS) with a diameter range of 10-50 nm were synthesized using the solution combustion method. High-resolution transmission electron microscopy (HRTEM) revealed a densely packed high surface area of SP2-hybridized carbon; however, there were no crystalline structural components, as can be seen from the scanning electron microscopy, HRTEM, X-ray diffraction, Raman spectroscopy, and thermal gravimetric analyses. Electrochemical and thermo catalytic... -
갈변억제제가 건조양파의 갈변과 품질에 미치는 영향

열풍건조양파의 품질을 향상시키기 위해서 갈변억제제를 선발하였고, 갈변억제제가 갈변도, 환원당, pyruvic acid및 vitamin C의 함량에 미치는 영향을 조사하였다. 절단한 양파는 $70^{circ}C$에서 5시간 열풍건조 하였고 수분함량은 3% 이내였다. 여러 가지 갈변억제제중 cyclodextrin과 corn starch를 갈변억제제로 선발하여 처리한 결과 4% 전분현탁액에 침지한 양파가 다른 처리구에 비교하여 갈변억제효과가 뛰어났고, 색의 변화와 갈변도는 상관성이 있었다. 갈변억제제를 처리한 건조 양파들은 대조군과 비교할 때 갈변을 약... -

열풍건조전 증류수에 침지온도(20, 40 및 $60^{circ}C$)와 침지시간 (6, 12 및 18분)에 따른 열풍건조양파(4% 수분도: 습량기준)의 갈색화 반응과 pyruvic acid 함량에 미치는 영향을 반응 표면 분석법으로 조사하였다. 나타난 수치들을 또한 이차 다항 회귀 모델로써 예측하였다. 이 실험범위에서 침지 시간보다 침지 온도가 갈색화 반응과 pyruvic acid 함량에 큰 영향을 미쳤다. 갈색화 반응은 $50^{circ}C$로 열풍건조시킨 대조구(O.D.=0.168)와 비교하여 $50^{circ}C$의 열풍건조 중 최소화시키는 공정(O.D.=0.071)으로... -

Carbon materials with at least one dimension of 1?100 nm are called carbon nanomaterials. A significant body of previous research in physics, chemistry and biology has demonstrated that the properties of nano-composites are significantly different than those of the bulk materials [1]. Some unique phenomena, such as the quantum tunneling effect, and surface effects, have also been observed, and attributed to the large surface area and small size of the carbon nanomaterials. It has been reported...
