Xiaoya Xue,Jun Yu,Ying Han,Xiuzhen Xiao,Zhangping Shi,Haifang Mao,Dongsen Mao 한국공업화학회 2020 Journal of Industrial and Engineering Chemistry Vol.86 No.-
A series of Zr-based metal-organic frameworks (UiO-66) supported Rh–Mn catalysts with various metalloadings were prepared by using a co-impregnation method, and the catalytic activities wereinvestigated for the direct synthesis of ethanol-based C2+ oxygenates from CO hydrogenation. Thecatalysts were comprehensively characterized by means of N2 sorption, XRD, TEM, XPS, H2-TPR, andDRIFT. The structural and textural properties of the catalysts show clearly that the overall frameworkstructure of UiO-66 can be beneficial to the high dispersion of supported metals, but the synergistic effectof Rh and Mn would be influenced by the metal loading or Mn/Rh ratio. When the loadings of Rh and Mnreached 3 wt.% and 3 wt.%, the catalyst has the best catalytic activity with the highest yield of C2+oxygenates of 200.1 g/(kg h), which can be attributed to the enhanced CO dissociation ability of Rh sitesand weaker Rh CO band strength.

Identification and expression analysis of grape LRK10L-2 genes during grape fruit development
Ma Jin-Ping,Yin Xue-Ren,Wei Tong-Lu,Liu Hai-Nan,Pei Mao-Song,Yang Sheng-Di,Jin Hui-Ying,He Guang-Qi,Guo Da-Long 한국식물생명공학회 2022 Plant biotechnology reports Vol.16 No.1
LRK10L-2 is known to be related to the plant disease response, little information is available about the relationship of LRK10L-2 and fruit ripening. The protein physicochemical properties, conserved domains, gene structures, subcellular locali- zation, expression patterns during grape fruit development and promoter activity of the members of grape LRK10L-2 gene family were explored in this study. A total of 109 LRK10L-2 family gene members were identified, and mainly distributed on chromosome 16. Almost all of them were located in the plasma membrane. Most of the LRK10L-2 genes contain four or five motifs, ranging from 0 to 5 introns and have the cis-acting elements related to hormones in their promoter regions. There were 20 pairs of tandem duplicates and 293 pairs of segmental duplication in LRK10L-2 family genes. It was proved that the expression of LRK10L-2 gene varied at the different fruit development stages of 'Kyoho' and its early-ripening bud mutant, ‘Fengzao’. The subcellular localization of VIT_16s0098g00160 and VIT_16s0098g00400 were in the plasma membrane, and had a significant enrichment of the GUS signal in N.benthamiana leaves for the promoter. The results lay a solid basis for the further functional researches of the LRK10L-2 genes for grape fruit ripening.

Double stranded targets on the cDNA microarray contain representatives of both the coding and noncoding strands, which will introduce hybridization competition with probes. Here, the effect of double and single strands of targets on the signal intensity and the ratios of Cy5/Cy3 within the same slide were compared. The results show that single stranded targets can increase the hybridization efficiency without changing the Cy5/Cy3 ratio. Based on these results, a new strategy was established by generating cDNA targets with asymmetric PCR, instead of conventional PCR, to increase the sensitivity of the cDNA microarray. Furthermore, the feasibility of this approach was validated. The results indicate that the cDNA microarray system based on asymmetric PCR is more sensitive, with no decrease in the reliability and reproducibility as compared with that based on conventional symmetric PCR.

Analysis of Cancer Incidence in Zhejiang Cancer Registry in China during 2000 to 2009
Du, Ling-Bin,Li, Hui-Zhang,Wang, Xiang-Hui,Zhu, Chen,Liu, Qing-Min,Li, Qi-Long,Li, Xue-Qin,Shen, Yong-Zhou,Zhang, Xin-Pei,Ying, Jiang-Wei,Yu, Chuan-Ding,Mao, Wei-Min Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.14
Objective: The Zhejiang Provincial Cancer Prevention and Control Office collected cancer registration data during 2000 to 2009 from 6 cancer registries in Zhejiang province of China in order to analyze the cancer incidence. Methods: Descriptive analysis included cancer incidence stratified by sex, age and cancer site group. The proportions and cumulative rates of 10 common cancers in different groups were also calculated. Chinese population census in 1982 and Segi's population were used for calculating age-standardized incidence rates. The log-linear model was used for fitting to calculate the incidence trends. Results: The 6 cancer registries in Zhejiang province in China covered a total of 60,087,888 person-years during 2000 to 2009 (males 30,445,904, females 29,641,984). The total number of new cancer cases were 163,104 (males 92,982, females 70,122). The morphology verified cases accounted for 69.7%, and the new cases verified only by information from death certification accounted for 1.23%. The crude incidence rate in Zhejiang cancer registration areas was $271.5/10^5$ during 2000 to 2009 (male $305.41/10^5$, female $236.58/10^5$), age-standardized incidence rates by Chinese standard population (ASIRC) and by world standard population (ASIRW) were $147.1/10^5$ and $188.2/10^5$, the cumulative incidence rate (aged from 0 to 74) being 21.7%. The crude incidence rate was $209.6/10^5$ in 2000, and it increased to $320.20/10^5$ in 2009 (52.8%), with an annual percent change (APC) of 4.51% (95% confidence interval, 3.25%-5.79%). Age-specific incidence rate of 80-84 age group was achieved at the highest point of the incidence curve. Overall with different age groups, the cancer incidences differed, the incidence of liver cancer being highest in 15-44 age group in males; the incidence of breast cancer was the highest in 15-64 age group in females; the incidences of lung cancer were the highest in both males and females over the age of 65 years. Conclusions: Lung cancer, digestive system malignancies and breast cancer are the most common cancers in Zhejiang province in China requiring an especial focus. The incidences of thyroid cancer, prostate cancer, cervical cancer and lymphoma have increased rapidly. Prevention and control measures should be implemented for these cancers.
