Background : Korean mountain ginseng (Panax ginseng C.A. Meyer) are difficult to industrially apply because of its scarcity and high cost. Advances in plant biotechnology have made it possible to produce mountain ginseng on a large scale using adventitious root cultures in bio-reactors. This study was conducted to develop a cosmetic emulsion using ginsenoside and physiological activity - enhanced raw materials by fermentation process. Methods and Results : Wild ginseng adventitious roots were fermented with Pediococcus pentosaceus HLJG 0702 (KACC 81017BP). ginsenoside contents was analysed by using HPLC. Antioxidant activity was measured by DPPH and ABTS radical scavenging activity and whitening effect was measured by tyrosinase inhibitory activity. After microfluidizer processing was performed to prepare emulsions with homogenized particles, particle size and distribution were measured through a transmission electron microscop e(TEM). Particle stability compares pH, viscosity, light and zeta potential. When fermented with Pediococcus pentosaceus HLJG 0702, the highest change rates of Rg3, Rk1 and Rg5 were shown and the antioxidant activity was increased. The whitening effect was 73.2 ± 0.9% when treated at 100 ㎍/㎖, 1.5 times higher than the control. The optimum particle size and distribution were shown to be 418.0 ± 14.9 ㎚ for 6 times treatment with 0 - 10 times microfluidizer treatment. Stability was about 3% in pH, viscosity and light test. the zeta potential was found to be homogeneous at –33.33 mV. Conclusion : Pediococcus pentosaceus HLJG 0702 Fermented Wild ginseng adventitious roots were found to have effective ingredients and improved physiological activity. We have also developed emulsions that exhibit optimal particle size and distribution

Background: Purple potato contain sufficient phenolic compound and flavonoid which has high antioxidant capacity. Due to poor water solubility of phenolic compounds and quick oxidation of anthocyanin, we could not get maximum health benefits from purple potato. Therefore, we developed surfactant based aqueous nano suspension to enhance the solubility of phenolic compounds and protect the oxidation of anthocyanin from purple potato. Methods and Results: Two types of surfactant were used in this experiment based on hydrophilic-lycophilic balance viz. Brij and Span. In our study, lycophilic surfactant showed highest efficiency in TP extraction compared to water and lipophilic surfactant below 10 mM concentration. On the other hand, lipophilic surfactant showed highest efficiency in extracting flavonoid content. Conclusion: It is concluded that hydrophilic surfactant was significantly increased phenolic compounds five times, and lipophilic surfactant increased flavonoid two times, and anthocyanin three times compared to control. Therefore, total antioxidant capacity was increases two times compared to control.

Background : The study about cultured wild ginseng root (Panax ginseng C. A. Meyer) have been reported mainly ginsenosides in saponins family. However metabolites of fermented wild ginseng roots by microorganisms was not reported yet. Methods and Results : Cultured wild ginseng roots were used for fermentation of ginseng roots using Pediococcus pentosaceus and other bacterial strains. We analyzed different types of ginsenoside contents, metabolite and enzyme contents, and gene expression by using microorganisms. Results showed considerable differences in ginseonoside contents specially Rk1 and Rg5. The highest enzyme activity level was by Glutathione reductase (GR) and Glutathione S transferase (GST) in fermented ginseng roots than control (non-fermented), whereas Glutathione peroxidase (GPX) and Peroxidase (POD) contents were reduced. Score plots and loading plots of principal components 1 of the PCA result obtained from the data on 43 metabolites in fermented wild ginseng root of five conditions. The concentration of metabolite such as β-alanin and 4-aminobutyric acid (GABA), which is used to improve memory were increased in fermented ginseng roots than control. We found functional gene in wild ginseng root related with metabolic process. The APX gene expression gradually increased in fermented ginseng root with respect to fermentation times. Conclusion : In this study, accumulation of functional metabolite in cultured ginseng r

The study aimed to evaluate the usability of sterile bag collection (SBC) urinalysis and urine culture for diagnosing urinary tract infections (UTI). Urine culture is key for diagnosing UTI, and transurethral catheterization (TUC) or suprapubic aspiration is recommended for non-toilet-trained children. Although urine testing using SBC is non-invasive and easy, UTI can be diagnosed only if other criteria including clinical symptoms and positive urinalysis results are met. This study included 228 infants who were hospitalized for unexplained fever from October 2015 to June 2016. TUC culture, SBC urinalysis, and urine culture were performed for all patients. UTI was diagnosed when the TUC culture results met the criterion of ≥104 colony-forming units (CFU)/mL. When UTI diagnosis was made based on SBC urine colony counts ≥105 CFU/mL, the false-positive and false-negative rates were 6.3% and 70.0%, respectively. When the criterion was set as ≥104 CFU/mL, they were 23.7% and 30.0%, respectively. When both the criteria of ≥105 CFU/mL and positive urinalysis results were met, the false-positive rate was 2.4%, and the false-negative rate was 80%. Our results suggest that diagnosing UTI using SBC urinalysis and urine culture is not useful in infants with unexplained fever.

Anaerobic mesophilic batch tests of food waste and food waste leachate collected from food waste treatment facility were carried out to evaluate their ultimate biodegradability and two distinctive decay rate coefficients (k1 and k2) with their corresponding degradable substrate fractions (S1 and S2), respectively. Each 3 liter batch reactor was operated for more than 60 days at substrate to inoculum ratio (S/I) of 0.5 as an initial total volatile solids (TVS) mass basis. Result of Ultimate biodegradability of 74 ~ 83% for food waste and 85 ~ 90% for food waste leachate were obtained respectively. The readily biodegradable fraction of 85 ~ 93% (S1) of food waste Biodegradable Volatile Solids (BVS, So) degraded within the initial 15 days with a range of of 0.151 ~ 0.168 day−1, whereas the rest slowly biodegradable fraction (S2) of BVS degraded for more than 53 days with the long term batch decay rate coefficients of 0.009 ~ 0.010 day−1. For the food waste leachate, the readily biodegradable portion (S1) appeared to be 92 ~ 94% of BVS (So), which degrades with of 0.172 ~ 0.206 day−1 for an initial 15 days. Its corresponding long term batch decay rate coefficients were 0.005 ~ 0.009 day−1. It is recommended that the hydraulic retention times of mesophilic anaerobic digesters be 16 days for the food waste and 15 days for the food waste leachate, respectively. However a safety factor should be considered when designing a full scale plant.

Background : Plants are the rich source of antioxidants, which plays a very important role in maintaining human health. Their antioxidant property protects cells of different organs of human beings against free radicals and free radical mediated diseases. Even though, there is lack of knowledge on the antioxidant effect of lutein present in plants. In the present study, lutein was isolated from the GreenTea leaves (Camellia sinensis) which is used as a dietary source. Methods and Results : The procedure adopted for the isolation and purification of lutein using acetone extraction and preparative high performance liquid chromatography (HPLC) is simple and less time consuming. Free radicals scavenging activity of isolated lutein from acetone extract of GreenTea was assessed by DPPH radical scavenging assay and reducing power. The isolated lutein scavenged 79% of DPPH radicals at 20 ㎍/㎖ and two fold lower concentration compared to the standard antioxidants (α-tocopherol). No significant differences were found between the reducing power of the lutein and BHT when their concentrations were high. However, significant differences were observed at relatively low concentrations, the reducing power of lutein was isolated from the GreenTea leaves was stronger than those of their acetone extract and standard antioxidants (BHA). Both electron spin resonance (ESR) and in vitro assay confirmed that lutein was isolated from the GreenTea leaves, exhibited a greater capacity for scavenging superoxide (O2 •－) and hydroxyl (OH •) radicals than standard antioxidants β-carotene and α-tocopherol respectively. Conclusion : The results proven that lutein isolated from GreenTea leaves has an efficient antioxidant ability, it could serve as an antioxidant to scavenge reactive oxygen species.

Background : Lutein, a xanthophyll, consists of chains with 8 conjugated double bounds containing closed rings on each end of the chain. This carotenoid is found in fruits and vegetables, especially dark green leafy vegetables such as green tea. In this study, we investigated the anticancer effects of purified lutein from green tea on human cancer cell lines containing prostate carcinoma cancer cells (LNCaP). Methods and Results : Prostate carcinoma cancer cells (LNCaP) were cultured and evaluated the inhibitory effect of lutein isolated from green tea compared other carotenoids (β-carotene and lycopene) on cell proliferation. Cyclin D1 and PCNA were evaluated as cell differentiation. In results, PCNA/cyclin regulates the initiation of cell proliferation by mediating DNA polymerase. Under cultural conditions, lycopene remarkably suppressed the PCNA expression prostate cancer cell line LNCaP in higher doses (20 μM - 100 μM) statistically. However, β-carotene and lutein presented the less inhibitory effects on PCNA expression. Determination of PCNA expression in control and treated cells demonstrates that lycopene did affect proliferation in LNCaP cancer cells in dose-dependent manner. However, β-carotene and lutein suppressed the cyclin D1 expression in dose-dependent manner but no in lycopene group. These results indicate that differ carotenoids presented the various suppressive ability of PCNA and cyclin D1 expression in cell proliferation. Conclusion : In conclusion, lutein suppressed the carcinogenesis of induced prostate cancer cell line by acting as a suppressor for inhibiting the expression of cyclin D.

Background : Angelica gigas is a biennial or short lived perennial plant found in China, Japan, and Korea. The root of Angelica gigas has been used in oriental traditional medicine and is marketed as a functional food product in Europe and North America. Cham-Dang-Gui (Korean Angelica, the dried root of Angelica gigas Nakai (AGN)) has been principally cultivated in Korea and used as a Korean medicinal herb. It contains several chemicals, such as pyranocoumarins, essential oils, and polyacetylenes. Methods and Results : Fresh Angelica gigas Nakai was purchased from Pyeongchang (Korea). Standard samples of D, DA were obtained from Korea Promotion Institute for Traditional Medicine Industry (Gyeongsan, Korea). Soluplus was purchased from BASF (Ludwigshafen, Germany). AGN was dried in the oven at 55°C for 24 h and cooled at room temperature. The AGN sample was then stored at 4°C until milling. Oral solid formulations based on Angelica gigas Nakai and Soluplus were prepared by the hot melt extrusion (HME) method. AGN was pulverized into coarse and ultrafine particles, and their particle size and morphology were investigated. Ultrafine AGN particles were used in the HME process with high shear to produce AGN-based formulations. In simulated gastrointestinal fluids (pH 1.2 and pH 6.8) and water, significantly higher amounts of the major active components of AGN, decursin (D) and decursinol angelate (DA), were extracted from the HME-processed AGN/Soluplus group than the AGN EtOH extract group (p < 0.05). Based on an in vivo pharmacokinetic study in rats, the relative oral bioavailability of decursinol (DOH), a hepatic metabolite of D and DA, in administered mice was 8.75-fold higher than in AGN EtOH ext-treated group. Conclusion : Soluplus-included solid formulation prepared by HME can be a promising carrier for oral delivery of phytochemicals. These findings suggest that HME-processed AGN/Soluplus formulation could be a promising therapeutic candidate for oral bioavailability.

Background : This study was performed to investigate by antioxidant activity, total phenolic contents, total flavonoid contents, and effective component of Astragalus membranaceus treated with different artificial light Sources (fluorescent lamp, red, blue, green, white, LEP). Methods and Results : We investigated the effects of various artificial light sources on the DPPH radical activity, total phenol and flavonoid contents, tyrosinase activity and main flavonoid compounds contents (formononetin and calycosin) and other biological activities in A. membranaceus. Antioxidant activities were 53.6% as the highest level of activity under LEP light. Growth under LEP light also produced the highest total phenolic and flavonoid contents of 36.05 and 5.94 mg/ml, respectively. Extracts from plants grown under LEP light caused the highest inhibition of tyrosinase activity with inhibition of 35.37, 61.87, and 65.49%, respectively, for extract concentrations of 100 μg/ml, 500 μg/ml, and 1000 μg/ml compared with other artificial light treatments. Conclusion : Little information is available on the influence of LED and LEP light sources on antioxidant production or other biological activities in A. membranaceus. Our goal in this study was to determine the effects of LED and LEP artificial light sources on the production of new functional compounds in A. membranaceus.

The effect of sudden changes of water temperature (WT) on the survival rate and physiological responses of the red spotted grouper (Epinephelus akaara) were examined by manipulating WT control system for 9 days. Experimental condition was divided in two different regimes at low (from 10°C to 4°C, decreased 1℃/d) and high (from 28°C to 34°C, increased 1°C/d) WT. Survival rate of experimental fishes were observed, and determined the changes of hematological characteristics by analyzing plasma levels of cortisol, glucose, total protein, and electrolytes (Na+, Cl–, K+). No mortality was observed until low WT 6°C (144 h) and high WT 32°C (96 h), and 100% mortality was observed at low WT 4°C (216 h) and high WT 35°C (171 h). Plasma levels of cortisol and glucose increased rapidly as decreasing WT, and the loss of swimming ability and respiration response was observed at low WT 7°C and high WT 34°C conditions.

Safflower (Carthamus tinctorius L.) seeds have long been clinically used in Korea to promote bone formation and prevent osteoporosis. In addition, the safflower buds (SB) were found to have more useful functional ingredients than safflower seed. Thus, we investigated the preventive effects of SB diet in ovariectomized (OVX) rats. The rats were divided into five groups; sham operated group, OVX alone group, OVX plus 17β-estradiol (E2 10 ㎍/㎏, i.p.) and OVX plus SB diet feeding group (0.3% or 1%). Feeding of SB diet (0.3% or 3%) to OVX rats markedly increased trabecular formation in femur compared to OVX rats. Feeding of SB diet (0.3% or 3%) to OVX rats also decreased TRAP activity compared to OVX rats. These results suggest that SB diets have bone sparing effects by the decrease of osteoclast activity. We also observed that OVX rats fed with SB diet (0.3% or 3%) exhibited the decrease of calcium and phosphorus in serum compared to OVX-induced rats. Therefore, SB may be beneficial for the patients of osteoporosis, especially in postmenopausal women.

In this study, antioxidant and anti-inflammatory activities of water, methanol, and ethanol extracts obtained from Allium hookeri root were evaluated. The ethanol extract of A. hookeri was found to possess the strongest reducing power and also exhibited dominant effects on scavenging of nitrites, DPPH radicals, and superoxide radicals. The water extract showed more efficient DPPH and hydroxyl radical-scavenging activities than those of the methanol extract. Furthermore, the inhibitory activity against nitric oxide (NO) production in RAW 264.7 macrophages was evaluated to elucidate the anti-inflammatory properties of the extracts. Results indicated that all the extracts of A. hookeri exerted inhibitory activities against NO production, especially the ethanol extract (IC5029.13μg/mL). Total phenolic and total flavonoid contents were found to be abundant in the ethanol extract, with values of 24.96 mg gallic acid equivalent/g extract and 4.27 mg rutin equivalent/g extract, respectively. Total thiosulfinate content was determined for the first time and a high amount was present in the ethanol extract (14.2 μM/g extract). These results suggest that A. hookeri root has antioxidant and anti-inflammatory properties and could be used as a natural source for the development of pharmaceutical agents or functional foods.

Zinc finger nucleases (ZFNs) have been used for targeted mutagenesis in eukaryotic cells. Custom-designed ZFNs can induce double-strand breaks (DSBs) at a specific locus. Our custom ZFN dimer was designed 3-finger of left and 4-finger of right with 2 kb size using 2A. A Ti-plasmid vector, pTA7002 containing the target site of SSS4A gene for a ZFN pair, that was shown to be active in yeast, was integrated in the rice genome. This promising technique for genome engineering was induced into 4 exon region of SSS4A gene in rice genome using Agrobacterium-mediated transformation. The SSS4A full-length cDNA was 5,070 bp consisting of a 318 bp 5′-untranslated region (UTR), a complete ORF of 2,928 bp encoding a polypeptide of 975 amino acids and a 3′-UTR of 1,824 bp. The vector is based on glucocorticoid receptor inducible gene expression system. Thus, SSS4A::ZFN expression was tightly controlled and the phenotype in low concentrations 10uM of the glucocorticoid hormone dexamethasone (DEX). In plant cells, transient ZFN expression is achieved by direct gene transfer into the target cells. For an alternative, ZFN delivery and production of mutant plants using a tobacco transient expression system for indirect transient delivery of ZFNs into a variety of tissues and cells of plants. ZFN activity was determined by PCR and sequence analysis of the target site. ZFN induced plants were obtained in up to 2% of the PCR products, consisting of deletions ranging between 1and 100 bp and insertions ranging between 1 and 10 bp. Our results describe an alternative to direct gene transfer for ZFN delivery and for the production of mutated rice.

GWAS (Genome-wide association study) provides a useful to associate phenotypic variation to genetic variation. It has emerged as a powerful approach for identifying genes underlying complex diseases or morphological traits at an unprecedented rate. Despite benefits, there are only a few examples applied in crop plants due to lack of effective genotyping techniques and well prepared resources for developing high density haplotype maps. In this study, 350 core accessions selected from almost 5,000 Capsicum accessions were used for GWAS. We are planning to construct a high-density haplotype map using GBS platform and perform GWAS for various agronomic traits including fruit traits and metabolites related to pungency to identify genes controlling the traits. These results will not only provide a list of candidate loci but also a powerful tools for finding genetic variants that can be directly used for crop improvement and deciphering the genetic architecture of complex traits.
