| 1 | Perturbation of Wood Cellulose Synthesis Causes Pleiotropic Effects in Transgenic Aspen显示文摘在树上的纤维素生合成的基因操作可以提供新奇卓见进树的生长和发展。探索这可能性,一棵白杨的 overexpression 第二等的联系墙的纤维素 synthase (PtdCesA8 ) 基因在转基因的白杨(Populus tremuloides L.) 被尝试并且出人意料地象它的内长的对应物一样导致了 transgene 的 silencing。转基因的白杨植物的主要的轴快速停止成长,并且弱树枝采用了一个哭泣的生长习惯。而且,转基因的植物开始开发了更小的叶子和一个不太广泛的根系统。几乎没象 10% 纤维素一样包含的转基因的白杨植物的第二等的木部(木头) 使正常化与典型地在正常白杨木头发现的 41% 纤维素相比弄干重量。在纤维素的这巨大的减小被木质素(35%) 和非有纤维质的多糖(55%) 的比例的增加在控制植物与 22% 木质素和 36% 非有纤维质的多糖相比伴随。生产的转基因的茎典型崩溃或改变了第二等的墙形态学并且极大地包含了的不规则的木部容器减少了水晶的纤维素的数量。这些结果在维持要求在树上建立垂直生长习惯的力量和结构的正直在第二等的木部以内表明第二等的墙纤维素的基本角色。 | Chandrashekhar R Joshi Shivegowda Thammannagowda Takeshi Fujino Ji-Qing Gou Utku Avci Candace H.

| 2 | Quantitative analysis of Boehm' s GC显示文摘The term garbage collection describes the automated process of finding previously allocated memorythatis no longer in use in order to make the memory available to satisfy subsequent allocation requests. Wehave reviewed existing papers and implementations of GC, and especially analyzed Boehm' s C codes, which isa real-time mark-sweep GC running under Linux and ANSI C standard. In this paper, we will quantitatively an-alyze the performance of different configurations of Boehm' s collector subjected to different workloads. Reportedmeasurements demonstrate that a refined garbage collector is a viable alternative to traditional explicit memorymanagement techniques, even for low-level languages. It is more a trade-off for certain system than an all-or-nothing proposition. | GUAN Xue-tao~*, ZHANG Yuan-rui, GOU Xiao-gang, CHENG Xu (MicroProcessor R & D Center, Peking University, Beijing 100871, China, | 2003 | Journal of Harbin Institute of Technology(New Series)2003，10，3： | 2 |
| 3 | Knockout of glutathione peroxidase 5 down-regulates the piRNAs in the caput epididymidis of aged mice显示文摘The mammalian epididymis not only plays a fun dame ntal role in the maturati on of spermatozoa,but also provides protecti on agai nst various stressors.The foremost among these is the threat posed by oxidative stress,which arises from an imbalance in reactive oxygen species and can elicit damage to cellular lipids,proteins,and nucleic acids.In mice,the risk of oxidative damage to spermatozoa is mitigated through the expression and secretion of glutathione peroxidase 5(GPX5)as a major luminal scavenger in the proximal caput epididymidal segment.Accordingly,the loss of GPX5^-/-mediated protection leads to impaired DNA integrity in the spermatozoa of aged Gpx57 mice.To explore the underlying mechanism,we have conducted transcriptomic analysis of caput epididymidal epithelial cells from aged(13 months old)Gpx5^-/-m mice.This analysis revealed the dysregulation of several thousand epididymal mRNA transcripts,in eluding the downregulation of a subgroup of piRNA pathway gen es,in aged Gpx5^-/-mice.In agreeme nt with these fin dings,we also observed the loss of piRNAs,which potentially bind to the P-element-induced wimpy testis(PlWI)-like proteins PIWIL1 and PIWIL2.The absence of these piRNAs was correlated with the elevated mRNA levels of their putative gene targets in the caput epididymidis of Gpx5^-/-mice.Importantly,the oxidative stress response genes tend to have more targeting piRNAs,and many of them were among the top increased genes upon the loss of GPX5^-/-.Taken together,our findings suggest the existence of a previously uncharacterized somatic piRNA pathway in the mammalian epididymis and its possible invoIvement in the aging and oxidative stress-mediated responses. | Chen Chu Lu Yu Joelle Henry-Berger Yan-Fei Ru Ayhan Kocer Alexandre Champroux Zhi-Tong Li Miao He Sheng-Song Xie Wu-Bin Ma Min-Jie Ni Zi-Mei Ni Yun-Li Guo Zhao-Liang Fei Lan-Tao Gou Qiang Liu Samanta Sharma Yu Zhou Mo-Fang Liu Charlie Degui Chen Andrew L Eamens Brett Nixon Yu-Chuan Zhou Joel R Drevet Yong-Lian Zhang | 2020 | Asian Journal of Andrology2020，22，6： | 2 |
