丝瓜自交系主要经济性状配合力及遗传参数分析

按双列杂交设计,用Griffing分析方法,对6个丝瓜自交系的10个主要经济性状的配合力及遗传参数进行分析.结果表明:各性状的一般配合力方差和特殊配合力方差均达到极显著水平.P3和P6自交系的综合性状较优,可在育种中直接利用;P3×P4等4个组合具有较强的杂种优势,有一定的增产潜力.在育种工作中,对丝瓜第1雌花节位等3个性状宜早代选择,而对可溶性糖含量等其它性状应进行晚代选择.     

十种藤本植物边坡适应性研究

对边坡10种藤本植物的移栽成活率、植被覆盖度、萌蘖性能、苗长等性状进行了研究.结果表明:10种植物都能适合边坡条件,其中地枇杷、爬山虎、扶芳藤在边坡环境下表现最优,其次为薜荔、常春油麻藤.由此表明,地枇杷、扶芳藤适宜在边坡生长,具有较高的推广价值.

柔性人造装饰薄木制造工艺的研究

柔性人造装饰薄木是为克服人造薄木的脆性大、强度低、破损多等缺陷而研究开发的新型装饰材料.对人造薄木与无纺布胶合制造柔性人造装饰薄木的工艺及其参数和生产设备进行了研究,结果表明:用平压法生产柔性人造装饰薄木的工艺参数为上胶量20～30 g/m2,热压温度100°C,时间90 s,压力1.0 MPa. 该柔性人造装饰薄木具有良好的柔韧性能、外观质量和粘合性能,可广泛应用于室内装饰、直线和曲线封边及异型包覆等.     

基于完全自适应策略的遗传算法

为改善标准遗传算法的优化性能,延长种群搜索过程,提出了完全自适应策略的遗传算法.自适应策略不仅基于进化阶段,同时基于个体,特别采用了自适应的适应值转换策略,大大降低了早熟的概率,保证算法能以较大的概率收敛到全局最优解.

Identification of serum differential proteins in colorectal adenoma and early malignantly transformed adenoma by proteomics

AIM: To investigate the associated proteins and sensitive biomarkers for early diagnosis of colorectal adenocarcinoma by comparing the results of differential proteomic analysis between colorectal adenoma and early malignantly transformed adenoma. METHODS: Two-dimensional gel electrophoresis was used to define patterns of protein expressions of colorectal adenoma and early malignantly transformed adenoma. Proteins expressed differentially among groups were detected, cut out and analyzed by MALDI-TOF/TOF mass spectrometry. RESULTS: Two-dimensional protein maps of colorectal adenoma and early malignantly transformed adenoma were analyzed with gel-analysis software, an average of 1 672 spots in adenoma, 1 732 in early malignantly transformed adenoma were observed. 28 spots of a 1.5-fold change were found, including 15 proteins down-regulated and 13 up-regulated in early malignantly transformed adenoma, in which 23 proteins were identified by mass spectrometry, the rate of identification was 82.14%. 13 differential proteins were attained, 8 were up-regulated and 5 were down-regulated, which was classified to 6 categories, including protease inhibitor, complement, immunoglobulin, keratoproteins, signal transduction protein and function-unknown proteins. CONCLUSION: The changes of serum proteins in early malignantly transformed adenoma from adenoma can be identified by proteomic technology. Proteins detected in the study may provide new biomarkers correlated with biological behavior of colorectal adenocarcinoma.
