Tropical plant rubber tree (Hevea brasiliensis) is the sole source of commercial natural rubber and low-temperature stress is the most important limiting factor for its cultivation. To characterize the gene expression profiles of H. brasiliensis under the cold stress and discover the key cold stress-induced genes. Three cDNA libraries, CT (control), LT2 (cold treatment at 4 °C for 2 h) and LT24 (cold treatment at 4 °C for 24 h) were constructed for RNA sequencing (RNA-Seq) and gene expression profiling. Quantitative real time PCR (qRT-PCR) was conducted to validate the RNA-Seq and gene differentially expression results. A total of 1457 and 2328 differentially expressed genes (DEGs) in LT2 and LT24 compared with CT were respectively detected. Most significantly enriched KEGG pathways included flavonoid biosynthesis, phenylpropanoid biosynthesis, plant hormone signal transduction, cutin, suberine and wax biosynthesis, Pentose and glucuronate interconversions, phenylalanine metabolism and starch and sucrose metabolism. A total of 239 transcription factors (TFs) were differentially expressed following 2 h or/and 24 h of cold treatment. Cold-response transcription factor families included ARR-B, B3, BES1, bHLH, C2H, CO-like, Dof, ERF, FAR1, G2-like, GRAS, GRF, HD-ZIP, HSF, LBD, MIKC-MADS, M-type MADS, MYB, MYB-related, NAC, RAV, SRS, TALE, TCP, Trihelix, WOX, WRKY, YABBY and ZF-HD. The genome-wide transcriptional response of rubber tree to the cold treatments were determined and a large number of DEGs were characterized including 239 transcription factors, providing important clues for further elucidation of the mechanisms of cold stress responses in rubber tree.

The antioxidant capacities, total phenolic contents (TPC), and total quercetin contents (TQC) of a red (Chenjujuck), a yellow (Sunpower), and a white (Grasier) onion cultivar were determined in this study. Onion was separated into edible portion and dry skin. In the case of edible portion, the yellow onion had the highest antioxidant activity, followed by the red onion. The white onion showed neither antioxidant activity nor quercetin compounds. On the other hand, the dry skin of the red onion showed higher antioxidant activity than yellow onion skin. The white onion skin had slight antioxidant activity, low TPC, and no quercetin compounds. In addition, the flavonoid compounds of the edible portion and dry skins of these colored onions were analyzed by UFLC(ultra-fast liquid chromatography). The major compounds were quercetin 3,4-diglucoside and quercetin 4- glucoside in yellow and red onion edible portion, whereas the major compounds in yellow and red onion skins were quercetin 4- glucoside, quercetin, and quercetin 3,4-diglucoside.

In recent years a growing number of South Korea’s films and TV dramas went intoChina,and they were very popular in cinema, television and DVD. However, as the difference in culture between China and South Korea, the meaning of their names would be changed when they were translated to Chinese. More than 600 South Korean films and TV dramas which were input into China from 2001 to 2012 have been researched in this paper. We discussed the features of their Chinese names and real names and analyzed the translation states of the South Korean film and TV drama in 21st century from aSkopos Theoryperspective.

Rice(Oryza sativa L.) feeds more than 50% of the world’s population and is one of the most important crops in the world. To evaluate the variation between different rice classfications, genetic diversity amoung a diverse set of rice collection including 59 breedlines, 23 landraces, 18 weedy rices and 35 introductions were analysed using 134 SSR markers located on the 12 chromosomes. In total, 1269 alleles were identified with an average of 9.47 per locus. Of the 1269 alleles, 460 (36.2%) were common, with a frequency of 0.05–0.5; 741 (58.4%) were rare (frequency < 0.05) and 68 (5.4%) were abundant (frequency > 0.5). A relatively high Polymophism information content (PIC) value was detected in landraces with smaller number of accessions than that of breedlines. Model-based structure analysis revealed the presence of six subpopulations, which was essentially consistent with the clustering based on genetic distance. One hundred and eight accessions (80.0%) showed a clear relation to each cluster based on their inferred ancestry value (>70%), while the remaining 27 accessions (15.4%) of which nine from landraces and fifteen from introductions were categorized as admixtures. Landrace and introductions distributed to almost all the six subpopulations whereas most of breedlines distributed to two distinct subpopulations. In conculusion, landraces in the present study showed critical importance in preservation of genetic diversity and rice breeding programs.

Over-expression of de novo lipogenesis (DNL) genes is associated with the prognosis of various types of cancers. However, the effects of single nucleotide polymorphisms (SNPs) in these genes on recurrence and survival of non-small cell lung cancer (NSCLC) patients after surgery are still unknown. In this study, a total of 500 NSCLC patients who underwent surgery treatment were included. Eight SNPs in 3 genes (ACACA, FASN and ACLY) of the DNL pathway were examined using the Sequenom iPLEX genotyping system. Multivariate Cox proportional hazards regression and Kaplan-Meier curves were used to analyze the association of SNPs with patient survival and tumour recurrence. We found that two SNPs in the FASN gene were significantly associated with the recurrence of NSCLC. SNP rs4246444 had a significant association with lung cancer recurrence under additive model (hazard ratio [HR], 0.82; 95% confidence interval [95%CI], 0.67-1.00; p=0.05). Under the dominant model, rs4485435 exhibited a significant association with recurrence (HR, 0.75; 95%CI, 0.56-1.01; p=0.05). Additionally, SNP rs9912300 in ACLY gene was significantly associated with overall survival in lung cancer patients (HR, 1.41; 95%CI, 1.02-1.94, p=0.04) under the dominant model. Further cumulative effect analysis showed moderate dose-dependent effects of unfavorable SNPs on both survival and recurrence. Our data suggest that the SNPs in DNL genes may serve as independent prognostic markers for NSCLC patients after surgery.

The piezoelectric-hydraulic actuator is a hybrid device that consists of a hydraulic pump driven by a piezo-stack coupled to a conventional hydraulic cylinder. The actuator is of compact size, but can produce a moderate energy output. Such hybrid actuators are currently being researched and developed in many industrialized countries due to the requirement for high performance and compact flight systems. In a previous study, we designed and manufactured a unidirectional hybrid actuator. However, the blocking force was not as high as expected. Therefore, in this study, we redesigned the pump chamber and hydraulic cylinder and also improved the system by removing the air bubbles. Two different types of piezo-stacks were used. In order to achieve bidirectional capabilities in the actuator, commercial solenoid valves were used to control the direction of the output cylinder. Experimental testing of the actuator in unidirectional and bidirectional modes was performed to examine performance issues related to driving frequency, bias pressure, reed valve thickness, etc. The results showed that the maximum blocking force was measured as 970.2N when the frequency was 185Hz.

( Jin Xiao ),( Jun Jun Ma ),( Zhen Huang ),( Xinq I Qiao ) 한국액체미립화학회 2005 한국액체미립화학회 학술강연회 논문집 Vol.2005 No.-

Injection of fuel containing CO2 involves dissolving the gas into fuel prior to injection, which has potential to reduce the NOx and soot emissions in diesel engine. This paper presents an experimental study on the flash boiling and atomization process of transient spray of fuel containing CO2 spray by means of high speed imaging technology. Experiments were performed under atmospheric conditions on a diesel hole-type nozzle. The effect of injection pressure on the flash boiling and atomization process were evaluated, especially in the early stage of injection. The transient characteristics of the spray, such as spray-angle and spray tip penetration were also investigated. The images clearly display the developing process of flashing boiling spray . Experimental results show that fuel atomization will improve greatly when the concentration of dissolved CO2 in the fuel is larger enough. New insight into the flash boiling and atomization process of the fuel containing CO2 spray was obtained and possible mechanism to explain the phenomena was proposed.
