调脂降糖话燕麦

燕麦也叫野麦或雀麦，为禾本科一年生草本植物燕麦的种子。燕麦的脂肪含量居所有谷物之首，相当于大米、白面的4-5倍，且其脂肪主要由单一不饱和脂肪酸、亚麻油酸和次亚麻油酸所构成，单是亚麻油酸就占了全部不饱和脂肪酸的35%-52%，燕麦又含有人体所需的8种氨基酸与维生素E，其含量亦高于大米与白面，燕麦还含有维生素B1、B2与叶酸，以及钙、磷、铁、锌、锰等多种矿物质与微量元素。     

西藏拉萨地区燕麦高产优化栽培技术研究

燕麦具有良好的抗旱、抗寒性,是西藏人工草地的主要类型.通过正交试验对西藏燕麦栽培技术研究表明：青引2号、白燕8号为适宜品种,最佳播种密度在10kg/亩～12kg/亩;氮肥是影响燕麦籽粒产量的显著因子,品种和氮肥是影响生育期的显著因子,各因子均对干草产量无显著影响.     

西藏光稃野生燕麦与冬小麦远缘杂交选育应用研究技术总结

本课题主要研究了利用西藏光稃生燕麦与肥麦不同属间的远缘有性杂交合成的杂交材料,经中国农科院品质所生物抗逆研究室对其Ｆｙ－８,Ｆｙ－９和双亲酯酶同工酶分析后表明;Ｆｙ－８,Ｆｙ－９和双亲遗传背景完全不同,Ｆｙ－８,Ｆｙ－９为新的冬小麦麦种质类型。     

我国饲用燕麦产业发展现状及存在的问题和建议

本文针对我国饲用燕麦种子生产和饲草现状等,从燕麦产业发展现状、产业发展中存在的问题及燕麦产业发展建议等方面对我国饲用燕麦产业发展现状进行了分析。     

Bovine TMEM95 gene: Polymorphisms detecting in five Chinese indigenous cattle breeds and their association with growth traits

BackgroundTransmembrane protein 95 (TMEM95) plays a role in male fertility. Previous studies showed that genes with a significant impact on reproductive traits can also affect the growth traits of livestock. Thus, we speculated that the genetic variation of TMEM95 gene may have effects on growth traits of cattle.ResultsTwo SNPs were genotyped. The rs136174626 and rs41904693 were in the intron 4 and 3′-untranslated region, respectively. The linkage disequilibrium analysis illustrated that these two loci were not linked. The rs136174626 was associated with six growth traits of Nanyang cattle, four traits of Luxi cattle, and three traits of Ji’an cattle. For rs41904693 locus, the GG individuals had greater body height and abdominal girth in Ji’ an cattle than TT and TG individuals. In Jinnan cattle, GG and TT individuals had greater body height, height at hip cross, body length, and heart girth than TG individuals. The potential splice site prediction results suggest that the rs136174626 may influence the splicing efficiency of TMEM95, and the miRNA binding site prediction results showed that the rs41904693 may influence the expression of TMEM95 by affecting the binding efficiency of Bta-miR-1584 and TMEM95 3′-UTR.ConclusionsThe findings of the study suggested that the two SNPs in TMEM95 could be a reliable basis for molecular breeding in cattle.How to cite: Guo X, Zhang S, Yang H, et al.

Success breeds success: The linkage between relationship intensity and tangible outcomes in industry–university collaborative ventures

While advancing new technologies has not traditionally been a major focus of industry–university collaboration, this article stresses that industry–university alliances can be instrumental in facilitating the industrial firm's advancement of both knowledge and new technologies. To investigate this phenomenon, this study focuses on industry–university relationships within the context of university research centers. The results from this multi-method, cross-sectional study indicate that a positive, two-way linkage exists between the intensity of industry–university relationships and the level of tangible outcomes generated. Results also show that while organization size and length of relationship do not significantly affect these dynamics, the industrial firm's geographic proximity to the university research center does. The implications of these findings for both industrial firms and universities are discussed.

知识型新员工心理契约破坏研究新视角

从员工个体感知角度出发,探讨了知识型新员工在感知心理契约破坏的同时,员工对自身的义务认知的变化,即员工兑现的责任与他们承诺的责任有差异.通过时244名知识型新员工的问卷调查,结果验证了知识型新员工在入职两年内普遍感知心理契约遭受破坏,且多数员工未能履行他们承诺的责任,同时心理契约破坏和离职意愿对员工感知未能履行自己承诺的责任有显著的负向作用,而员工满意感与员工感知未能履行自己承诺的责任正相关.
