| 1 | Study on Laser Welding of Al Composite显示文摘The effects of laser welding parameter on strength of welded joints were studied. The mechanism for loss of joint strength was analyzed. It was pointed out that an important factor affecting joint strength is the reaction between matrix and reinforced phase. On the basis of this, the concept of critical St activity a[si]min was proposed. Using appropriate welding parameters and Si activity, high quality laser welded joints in an aluminum matrix composite SiCw/6061Al can be Successfully obtained. | Jitai NIU Zhonghong LAI MuZhen WANG Liming LIU and Lin WU National Key Laboratory of Advanced Welding Production Technology, Harbin institute of Technology, Harbin 150001, China | 2001 | Journal of Materials Science & Technology2001，17，1： | 3 |

| 4 | Effects of pituitary-specific overexpression of FSHα/β on reproductive traits in transgenic boars显示文摘Background: Follicle-stimulating hormone(FSH) is a gonadotropin synthesized and secreted by the pituitary gland.FSH stimulates follicle development and maturation in females. It also plays an important role in spermatogenesis in males, including humans and mice. However, the effects of FSH on male pigs are largely unknown. In this study,we generated transgenic pigs to investigate the effects of FSHα/β overexpression on reproductive traits in boars.Results: After five transgenic F_0 founders were crossed with wide-type pigs, 193 F_1 animals were obtained. Of these,96 were confirmed as transgenic. FSHα and FSHβ m RNAs were detected only in pituitary tissue. Transgenic boars exhibited significantly higher levels of FSHα and FSHβ m RNA, serum FSH, and serum testosterone, compared to ful-sib non-transgenic boars. Significant increases in testis weight, vas deferens diameter, seminiferous tubule diameter,and the number of Leydig cel s were observed, suggesting that the exogenous FSHα/β affects reproductive traits. Final y,transgenic and non-transgenic boars had similar growth performance and biochemical profiles.Conclusions: Pituitary-specific overexpression of FSHα/β genes is likely to impact reproductive traits positively, as indicated by enhancements in serum testosterone level, testis weight, the development of vas deferens, seminiferous tubules, and Leydig cells in transgenic boars. A high level of serum FSH induces secretion of serum testosterone,possibly by boosting the number of Leydig cells, which presumably increases the libido and the frequency of sexual activity in transgenic boars. Our study provides a preliminary foundation for the genetic improvement of reproductive traits in male pigs. | Wenting Li Yujun Quan Mengmeng Zhang Kejun Wang Muzhen Zhu Ye Chen Qiuyan Li Keliang Wu | 2018 | Journal of Animal Science and Biotechnology2018，9，1： | 1 |
