RePS: A Sequence Assembler That Masks Exact Repeats Identified from the Shotgun Data

Wang, Jun, Wong, Gane Ka-Shu, Ni, Peixiang, Han, Yujun, Huang, Xiangang, Zhang, Jianguo, ...

We describe a sequence assembler, RePS (repeat-masked Phrap with scaffolding), that explicitly identifies exact 20mer repeats from the shotgun data and removes them prior to the assembly. The...

Mouse dyskerin mutations affect accumulation of telomerase RNA and small nucleolar RNA, telomerase activity, and ribosomal RNA processing

Mochizuki, Yuko, He, Jun, Kulkarni, Shashikant, Bessler, Monica, Mason, Philip J.

Dyskerin is a nucleolar protein present in small nucleolar ribonucleoprotein particles that modify specific uridine residues of rRNA by converting them to pseudouridine. Dyskerin is also a component...

Infectious Molecular Clone of a Recently Transmitted Pediatric Human Immunodeficiency Virus Clade C Isolate from Africa: Evidence of Intraclade Recombination

Grisson, Ricky D., Chenine, Agnès-Laurence, Yeh, Lan-Yu, He, Jun, Wood, Charles, Bhat, Ganapati J., ...

Although human immunodeficiency virus type 1 (HIV-1) clade C continues to dominate the pandemic, only two infectious clade C proviral DNA clones have been described (N. Mochizuki, N. Otsuka, K....

Jembrana Disease Virus Tat Can Regulate Human Immunodeficiency Virus (HIV) Long Terminal Repeat-Directed Gene Expression and Can Substitute for HIV Tat in Viral Replication

Chen, Hexin, He, Jun, Fong, Steven, Wilcox, Graham, Wood, Charles

Jembrana disease virus (JDV) is a bovine lentivirus genetically similar to bovine immunodeficiency virus; it causes an acute and sometimes fatal disease in infected animals. This virus carries a very...

Gastric carcinoma with osteoclast-like giant cells: a case report and review of the literature*

Zheng, Li-duan, Yang, Xiu-ping, Pan, Hua-xiong, Nie, Xiu, He, Jun, Lv, Qing, ...

Gastric carcinoma with osteoclast-like giant cells (OGCs) is an extremely rare tumor. So far, only six cases have been reported in the literature. Here we report an additional case of this tumor in a...

An Evolutionary Approach to Adaptive Model-Building

Zhengjun Pan, Lishan Kang, Jun He, Yong Liu

Learning an input-output mapping from a set of examples can be regarded as a problem of model-building. From this point of view, by a hierarchical representation scheme for models, an evolutionary...
