Direct Observation of Radiative Flux in the Southern Yellow Sea
Lu, Lian-Gang,Yu, Fei,Diao, Xinyuan,Guo, Jingsong,Wang, Huiwu,Wei, Chuanjie The Korean Society of Oceanography 2008 Ocean science journal Vol.43 No.2
Direct measurements of four radiative components at air-sea boundary layer were conducted in the southern Yellow Sea during three cruises (seasons) in 2007. Simultaneous observations of meteorological (cloud cover, air temperature and humidity) and oceanographic (sea surface temperature) parameters were carried out. Observational results of radiative fluxes and meteorological and oceanographic parameters are presented. Mean diurnal cycles of four radiative components, net radiation, and sea surface albedo are calculated to achieve averages in different seasons. Net radiative fluxes in three seasons (winter, spring, autumn) are 8, 146, $60\;W/m^2$, respectively. Comparisons between the observed radiative fluxes and those estimated with formulas are taken.
Vertical Migration of Sound Scatterers in the Southern Yellow Sea in Summer
Lu, Lian-Gang,Liu, Jianjun,Yu, Fei,Wu, Wei,Yang, Xiaodong The Korean Society of Oceanography 2007 Ocean science journal Vol.42 No.1
Acoustic volume backscattering strength data were collected and Conductivity Temperature Depth (CTD) measurements were conducted in the southern Yellow Sea in summer 2005 and 2006. The high temporal and vertical resolution acoustic data measured with a 307 kHz Acoustic Doppler Current Profiler (ADCP) and a 250 kHz acoustic Doppler profile (ADP) had dominant diel variation, which resulted from vertical migration of sound scatterers. Some scatterers congregating in the bottom layer in the daytime migrated upward at dusk, and migrated downward into the bottom layer at dawn. The migration speeds were estimated. More than 33 days data show that the diel migration varies with time. The feature of migration measured with ADCP and ADP is consistent to some extent with what is described in the study on vertical migration of zooplankton in the southern Yellow Sea with conventional net samples.

Boiler efficiency and emission load of NOX are the key evaluation indicators of operation performance of the coal-fired boiler. It has become a popular academic research topic concerning the reduction of NOX emissions while maintaining the same boiler efficiency, as well as how to build a model for boiler emission. Based on a prediction model that is constructed for boiler efficiency and emission load of NOX with the application of deep belief algorithm, genetic algorithm is used to optimize the tilting angel of boiler burners and the flow velocity of pulverized coal, thereby effectively reducing the emission load of NOX. Simulation results indicate that this method effectively optimizes the parameters of the boiler, and provides a new way to optimize the parameters of the boiler.

The association between the NAD(P)H:quinone oxidoreductase 1 (NQO1) gene C609T polymorphism (rs1800566) and gastric cancer has been widely evaluated, but a definitive answer is so far lacking. We first conducted a case-control study to assess this association in a large Han Chinese population, and then performed a meta-analysis to further address this issue. Although our case-control association study indicated no significant difference in the genotype and allele distributions of C609T polymorphism between gastric cancer patients and controls, in the meta analysis involving 4,000 subjects, comparison of alleles 609T and 609C indicated a significantly increased risk (46%) for gastric cancer (95% confidence interval (95%CI) for odds ratio (OR)=1.20-1.79) in individuals with the T allele. The tendency was similar to the homozygote (OR=1.81, 95%CI: 1.16-2.84), dominant models (OR=1.41, 95%CI: 1.12-1.79), as well as recessive model (OR=1.58, 95%CI: 1.06-2.35). Stratified analysis by study design demonstrated stronger associations in population-based than in hospital-based studies. And ethnicity-based analysis demonstrated a significant association in Asians. We conclude that the NQO1 gene C609T polymorphism increases the risk for gastric cancer, especially in Asian populations.

A muscle-specific lipase gene of the bumblebee Bombus ignitus was cloned and characterized. This gene, which we named Bi-Lipase, consists of seven exons encoding 317 amino acid residues. Bi-Lipase possesses all the features of lipases, including GXSXG consensus motif and Ser-Asp-His catalytic triad. Expressed as a 37-kDa polypeptide in baculovirus-infected insect Sf9 cells, recombinant Bi-Lipase showed an optimal pH of 9.0 and exhibited its highest catalytic activity at 40℃. Furthermore, through the addition of tunicamycin to the recombinant virus-infected Sf9 cells, recombinant Bi-Lipase was found to be N-glycosylated. Northern and western blot analyses indicated that Bi-Lipase was expressed in the wing, thorax, and leg muscles. These results show that Bi-Lipase is a muscle-specific lipase, suggesting a possible role of Bi-Lipase in the utilization of lipids for muscular activity in B. ignitus.

Purpose: To retrospective assess the potential predictors for relapse and create an effective clinical mode for surveillance after orchidectomy in clinical stage I non-seminomatous germ cell testicular tumors (CSI-NSGCTs). Materials and Methods: We analyzed data for CSI-NSGCTs patients with non-lymphatic vascular invasion, %ECa < 50% (percentage of embryonal carcinoma < 50%), and negative or declining tumor markers to their half-life following orchidectomy (defined as low-risk patients); these patients were recruited from four Chinese centers between January 1999 and October 2013. Patients were divided into active surveillance group and retroperitoneal lymph node dissection (RPLND) group according to different therapeutic methods after radical orchidectomy was performed. The disease-free survival rates (DFSR) and overall survival rates (OSR) of the two groups were compared by Kaplan-Meier analysis. Results: A total of 121 patients with CSI-NSGCT were collected from four centers, and 81 low-risk patients, including 54 with active surveillance and 27 with RPLND, were enrolled at last. The median follow-up duration was 66.2 (range 6-164) months in the RPLND group and 65.9 (range 8-179) months in the surveillance group. OSR was 100% in active surveillance and RPLND groups, and DFSR was 89.8% and 87.0%, respectively. No significant difference was observed between these two groups ($X_2=0.108$, P=0.743). No significant difference was observed between the patients with a low percentage of embryonal carcinoma (<50%) and those without embryonal carcinoma (87.0% and 91.9%, $X_2=0.154$, P=0.645). No treatment-related complications were observed in the active surveillance group whereas minor and major complications were observed in 13.0% and 26.1% of the RPLND group, respectively. Conclusions: Active surveillance resulted in similar DFSR and OSR compared with RPLND in our trial. Patients with low-risk CSI-NSGCTs could benefit from risk-adapted surveillance after these patients were subjected to radical orchidectomy.

Background: The objectives of the present study were to investigate the reliability and outcomes of computer-assisted techniques in mandibular reconstruction with a fibula flap and verify whether the surgical navigation system was feasible in mandible reconstructive surgery. Methods: Eight cases were enrolled in the computer assisted surgery (CAS) group and 14 cases in the traditional group. The shaping and fixation of the fibula grafts were guided by computer assisted techniques, which could be monitored with the BrainLAB surgical navigation system. The variation of mandible configuration was evaluated by CT measurement in the Mimics software, including the variation of length, width, height and gonial angle of the mandible. The 3D facial soft tissue alteration was also analyzed in 3D chromatogram by Geomagic software. Results: All 22 fibula flaps survived. The mandibular configurations and facial contours had a better clinic result in the CAS group. The length, width, height and gonial angle of the reconstructive mandible were more similar to the original one. The Wilcoxon rank sum test analysis suggested significant differences in the measurements. The chromatographic analysis also visually showed superiority over the traditional group. Conclusions: The computer assisted surgical navigation method used in mandibular reconstruction is feasible and precise for clinical application. The contour of the reconstructed mandible and facial symmetry are improved with computer techniques.

The aim of this study was to develop andcharacterize a self-microemulsifying drug delivery system(SMEDDS) of Brucea javanica oil (BJO) and transform theliquid formulation into solid granules. Solubility studies ofBJO and pseudo-ternary phase diagrams were used toidentify the most efficient self-emulsification region. Amethyl thiazolyl tetrazolium (MTT) assay was performedto identify cell apoptosis. Antitumor activity studies werealso employed to evaluate the BJO SMEDDS. The optimizedBJO SMEDDS in liquid and granule formulationsrapidly formed fine oil-in-water microemulsions with particlesizes\50 nm. Additionally, the MTT assay demonstratedthat BJO SMEDDS had a significant effect oncancer cells, and antitumor activity studies showedremarkable inhibition of S180 tumors. The BJO SMEDDS,optimized to have good characteristics, was successfullytransformed into solid granules by adsorbing onto crospovidone. The studies of the release of the BJO SMEDDS ofliquid and granules in vitro suggested that the release ofBJO was enhanced by the SMEDDS. These studiesrevealed that the new self-microemulsifying systems ofliquid and granule forms might be promising strategies forthe oral delivery of the poorly water-soluble drug BJO.

In controlling the robot interacting with the external environment, an important role is played by the force/moment sensors. To design a good force sensor, we need to make a good model first. This paper presents a systematic modeling method of one type of force/moment sensor. A model of a previously designed sensor has been built on the basis of static and kinematic equations and a block form of the strain compliance matrix is obtained using the model.

Two genes coding for eukaryotic translation initiation factors, eIF4E.a and eIF4E.c, were isolated from twelve accessions of Chinese cabbage (Brassica rapa L. ssp. pekinensis). Polymorphism analysis revealed that 94and 142 polymorphic sites were characterized from allele of BraeIF4E.a and BraeIF4E.c which produced complex haplotype structures. Six novel haplotypes were characterized from the two alleles respectively. Among the six novel haplotypes of BraeIF4E.a, three loss-of-function mutations were identified in which a conserved single nucleotide deletion mutation cause the early termination of BraeIF4E.a coding product; while for six new BraeIF4E.c haplotypes, their coding product show amino acid substitution mutations on non-conservative amino acid residues which might affect TuMV infection in Chinese cabbage.
