甲状腺癌是头颈外科及内分泌科最常见的恶性肿瘤,近年来在我国其发病率有上升趋势。2012年,甲状腺癌发病率为6.56/10万人。分化型甲状腺癌(differentiated thyroid carcinoma,DTC)起源于滤泡上皮细胞,是甲状腺癌中最常见的病理组织类型,占甲状腺恶性肿瘤的90%以上,其又分为乳头状癌(papillary thyroid carcinoma,PTC)和滤泡状癌(follic
Thyroid cancer is the most common malignant tumor of head and neck surgery and endocrinology. In recent years, the incidence of thyroid cancer in our country has been on the rise. In 2012, the incidence of thyroid cancer was 6.56 / 10 million. Differentiated thyroid carcinoma (DTC) originated in the follicular epithelial cells, is the most common histopathological types of thyroid cancer, accounting for more than 90% of thyroid malignancies, which is divided into papillary thyroid carcinoma (papillary thyroid carcinoma, PTC) and follicular carcinoma (follic

1945年初,美、英、苏盟军在欧洲战场上连战皆捷,终于攻入德国本土。直到这个时候,德国法西斯在各杀人工厂——集中营中所犯下的灭绝人性的滔天罪行,才初次为世界所知。当时,
由辽宁省农科院作物育种研究所选育的“辽啤1号”啤酒大麦已于1993年底通过省农作物品种审定委员会的审定。经过7年的不懈努力,从引进的500多个啤酒大麦品种(品系)中筛选出的“辽啤1号”,具
目前,生产上杂交粳稻以利用BT型不育系为主,由于BT型不育系的育性不够稳定,同时单一细胞质的应用也使杂交粳稻的推广存在着潜在风险。因此,对其他类型粳稻不育系的研究和利用显得十分重要。已有的研究表明HL型、CL型粳稻不育系较好地协调了育性稳定性、开花习性和可恢复性几方面的矛盾。因此,研究HL、CL型粳稻不育系的育性遗传及恢复基因定位对选育HL型、CL型粳稻不育系及其相应的恢复系,解决目前生产上杂交粳
棍棒赶粉不仅可以提高杂交稻的制种产量,而且还有保纯的优点。两年来,笔者和同事们分别对棍棒赶粉和绳索赶粉的制种田进行对比调查,结果如下表: 从表列结果可以看出,在母本
随着现代生物技术的不断发展,种子已经不再只是农作物的繁殖器官,还作为如医药、化工等其他产业的生物载体。所以通过生物技术手段定向改良植物种子,已经成为现代植物基因工程上的重要课题。而种子特异性表达启动子则是进行植物种子基因工程改良的重要工具。在目前生产试验上采用的启动子大多数为组成型启动子,可启动外源基因在受体植物中非特异性的持续、稳定的表达,但不能从时间和空间上对外源基因的表达进行有效的调控,这可
