Chitin deacetylase (CDA) is an insect chitin degradation enzyme that catalyzes the deacetylation of chitin to form chitosan. In this study, combination of rapid-amplification of cDNA ends (RACE) technology with Cnaphalocrocis medinalis transcriptome database analysis revealed the presence of at least five C. medinalis CDAs (CmCDAs), which were CmCDA1, CmCDA2, CmCDA4, CmCDA5, and CmCDA6. The cDNA sequences of CmCDA1, CmCDA2, and CmCDA4 hadwhole open reading frame (ORF) for further analysis. Phylogenetic analysis indicated that insect CDAs could be categorized into five groups. CmCDAs' structural domain analysis revealed that all three CDAs contained the chitin deacetylase-like catalytic domain. CmCDA1 and CmCDA2 belong to Group I because they both contain the chitin-binding peritrophin-A domain (ChBD), low-density lipoprotein receptor class A domain (LDLa), and chitin deacetylase-like catalytic domain. CmCDA4 only contains ChBD and chitin deacetylase-like catalytic domain thus belongs to Group III. Tissue and developmental stage expression analysis showed that the expression levels of CmCDA1, CmCDA2, and CmCDA4 are significantly higher in the head than other tissues and also significantly higher in adults than in larvae. CmCDA5 had significantly higher expression in the integument than other tissues, suggesting potential roles in the process of degradation of chitin. In contrast, CmCDA5 showed relatively high expression in larvae. In conclusion, this study analyzed the cDNA sequences of three CDA genes and determined their expression and molecular characteristics, which provided a new sequence resource and improved the development of bio-pesticides and the biological pest control and contributed to management of this important agricultural pest.

Purpose The purpose of this study was to investigate the survival trends and patterns of failure in patients with stage II nasopharyngeal carcinoma (NPC) treated with radiotherapy (RT) and chemotherapy over the last 20 years. Materials and Methods Thirty-eight hundred and eight patients diagnosed with stage II NPC between January 1990 and December 2012 were involved in this retrospective cohort study. All patients were treated with RT. According to the main imaging techniques and RT technology, we categorized these patients into four calendar periods: 1990-1996, 1997-2002, 2003-2007, and 2008-2012. Overall survival (OS), progression-free survival (PFS), locoregional relapse-free survival (LRFS), and distant metastasis–free survival (DMFS) were served as the clinical outcome. Results After a median follow-up period of 84.7 months, we observed increasing trends in survival and disease control. The 3- and 5-year OS rates increased from 87.1% and 78.7% in the first calendar period to 97.4% and 94.5% in the last calendar period, respectively (p < 0.001). Additionally, significant increasing trends could be seen in the PFS and LRFS during the four calendar periods. In the subgroup analysis, the LRFS in patients older than 50 years at diagnosis showed greater improvement than younger patients. However, the rate of distant metastasis was stable and relatively low, as the 5-year DMFS ranged from 90.5% to 94.7% among the four calendar periods. Conclusion The survival rates in patients with stage II NPC showed increasing trends from 1990 to 2012. The advance of RT provided excellent locoregional control and enhanced OS.

Parallel match is an important concept for the parallel processing of the production system(PS). Considing the PS as a kernel of deduction knowledge, this paper presents a prototype of knowledge-based machine-KBM91 composed of the host-slave machine. The aim is to solve the match bottleneck problem of the PS. Furthermore, the paper analyzes the designing thought, the working process and the architecture of KBM91, and proposes a new kind of knowledge-based language(KBL) which has been realized at present.

We have characterized a new male-sterile mutant in Arabidopsis that exhibits conditional sterility but has restored fertility when drought-stressed. This mutant,multiple impairments in male reproduction 1 (mimr1),shows pleiotropic defects in both vegetative and reproductive development. Examination with dissecting and scanning electron microscopes revealed that its pollen grains are not effectively released from the anther locule after dehiscence, and anther differentiation is defective. Growth of the style and stamen filaments are also abnormal. Histological analysis demonstrated that these phenomena are due not only to a noticeably reduced extension of the stamen but also greater elongation of the pistil. Genetic analysis indicated that mimr1 is a single locus recessive nuclear mutant. The mutation can be mapped to a locus strongly linked to a 1200-kb region on Chromosome 3. Meta-analysis of expression patterning presented several candidate genes in that region. No mutants with similar phenotypes have previously been reported, suggesting that mimr1 is a novel male-sterile locus. Characterization of MIMR1 will provide further insights into the molecular basis for the development of plant reproductive organs.

Effects of Cantharidinate on apoptosis of human colorectal cancer UTC-116 cells were investigated by means of 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay, H and E staining, flow cytometry, and Raman Spectra analysis. The results showed Cantharidinate to exert inhibitory action on proliferation of human colorectal cancer UTC-116 cells, inducing apoptosis, arresting cells in G1 phase, with decline of S and G2 phases. In addition, the results of Raman spectrum showed significant changes in the UTC-116 cells chemical structure with stretching after the application of Cantharidinate. Taken together, these results suggest that the treatment of human colorectal cancer with Cantharidinate may be associated with multiple molecular mechanisms for apoptosis. Furthermore, similar to fluorouracil, Cantharidinate should be considered as novel assistant drug for controlling the growth of human colorectal cancer UTC-116 cells.

Purpose The purpose of this study was to subdivide M1 stage nasopharyngeal carcinoma (NPC) patients with bone-only metastases for prognosis prediction while identifying the treatment effect of locoregional radiotherapy (LRRT) and metastasis radiotherapy (MRT) among patients with different risk. Materials and Methods From November 2006 to October 2016, a total of 226 patients with bone-only metastasic NPC were retrospectively enrolled. All patients developed distant lesions before receiving treatment. All potential prognostic factors were considered and the correlation of the M1 subdivisions with overall survival (OS) was determined by Cox regression hazards model. Kaplan-Meier curves were used to appraise survival condition and log-rank testing was used to compare the differences. Results The median follow-up time was 33.9 months (range, 3 to 126 months). According to multivariate Cox proportional hazard analysis, the number of metastatic lesions and Epstein-Barr virus (EBV) DNA status after palliative chemotherapy (PCT) were independent prognostic factors for OS. Thus, we subdivided patients into three risk groups according to these two factors. Systemic chemotherapy combined with LRRT may benefit patients in low- and intermediate-risk groups but not in the high-risk group. Further aggressive MRT based on systemic chemotherapy showed no survival benefit in any risk group. Conclusion The stratification of NPC patients with bone-only metastasis based on EBV DNA after PCT and the number of metastatic lesions provided promising prognostic value and could aid clinicians in person-specific treatment.

Large conductance calcium-activated potassiumchannels (Slo) play important roles in controllingneuronal excitability. At present, very little is known aboutthe function of Slo channels on ovarian development. Wecloned the SPSlo gene from the mud crab, Scylla paramamosain. This gene shows 91 and 93 % sequence identityto PISlo from the spiny lobster, Panulirus interruptus andCBSlo from the jonah crab, Cancer borealis, respectively. We isolated six variants of the SPSlo cDNA within S. paramamosain ovary tissue. Sequence analysis indicatedthat there were at least seven alternative sites in SPSlo,each with multiple alternative segments. Real-time PCRshowed that the SPSlo gene was expressed in various tissues,and highly expressed in brain and ovary. In addition,the expression of SPSlo changed throughout ovariandevelopment, highest at the early-developing stage (StageII) followed by a slow decrease in subsequent stages. Theseresults suggested that SPSlo channels may be implicated inthe ovarian development of the mud crab.

The disposal of spent radioactive ion exchange resin generated during the operation of nuclear facilitieshas always been a conundrum. The molten salt oxidation (MSO) for the treatment of mixed resin (MR)shows obvious superiority. In this work, ternary carbonate (Li2CO3-Na2CO3-K2CO3) and MR was usedas the molten salt system and the oxidation target, respectively. The oxidation behavior of MR was analyzedby varying the temperature and oxygen equivalent during the MSO process. By studying the effectof different oxygen equivalents on the oxidation efficiency, the oxygen equivalent of 125% could make theoxidation efficiency of MR reach 99.99% at 800 C. The composition of C, N and S containing exhaust gasproduced through MSO process of MR with temperature were almost consistent with the simulationresults. The exhaust gas was successfully adsorbed by molten carbonate to produce nitrate and sulfurcompounds. The carbonate has good absorption to harmful gases such as SO2, CO, NO, etc. The contentof SO2 from the highest 0.32% to 0, and 71.23% of sulfur in MR was trapped by molten carbonate asthe form of sulfate. This work has important implications for reducing the potential harm of radioactivewaste resin to the environment.

Ya-li Xue,Dong-hai Li,Jing-gong Liu 제어로봇시스템학회 2010 제어로봇시스템학회 국제학술대회 논문집 Vol.2010 No.10
Based on desired dynamic equation (DDE), a kind of PI controller tuning method is discussed in this paper. Using Nyquist stability criterion, the stable region of controller tunable parameter is calculated and compared with traditional PI controller, and then the necessity of introducing a scaling factor L is explained for better control performance. The DDE-based PI tuning method is applied to a gasifier temperature control. The simulation results show its feasibility with lower tuning efforts and better performance.
