Relative to genomes of other sequenced organisms, the human genome appears particularly enriched for large, highly homologous segmental duplications (> or =90% sequence identity and > or =10 kbp in length). The molecular basis for this enrichment is unknown. We sought to gain insight into the mechanism of origin, by systematically examining sequence(More)
Complex eukaryotic genomes are now being sequenced at an accelerated pace primarily using whole-genome shotgun (WGS) sequence assembly approaches. WGS assembly was initially criticized because of its perceived inability to resolve repeat structures within genomes. Here, we quantify the effect of WGS sequence assembly on large, highly similar repeats by(More)
It is known that physical linkage of TLR ligands and vaccine antigens significantly enhances the immunopotency of the linked antigens. We have used this approach to generate novel influenza vaccines that fuse the globular head domain of the protective hemagglutinin (HA) antigen with the potent TLR5 ligand, flagellin. These fusion proteins are efficiently(More)
We performed a detailed analysis of both single-nucleotide and large insertion/deletion events based on large-scale comparison of 10.6 Mb of genomic sequence from lemur, baboon, and chimpanzee to human. Using a human genomic reference, optimal global alignments were constructed from large (>50-kb) genomic sequence clones. These alignments were examined for(More)
An understanding of how centromeric transition regions are organized is a critical aspect of chromosome structure and function; however, the sequence context of these regions has been difficult to resolve on the basis of the draft genome sequence. We present a detailed analysis of the structure and assembly of all human pericentromeric regions (5(More)
Charge-neutral DNA nanoparticles have been developed in which single molecules of DNA are compacted to their minimal possible size. We speculated that the small size of these DNA nanoparticles may facilitate gene transfer in postmitotic cells, permitting nuclear uptake across the 25-nm nuclear membrane pore. To determine whether DNA nanoparticles can(More)
This work aims at developing a novel pathological brain detection system (PBDS) to assist neuroradiologists to interpret magnetic resonance (MR) brain images. We simplify this problem as recognizing pathological brains from healthy brains. First, 12 fractional Fourier entropy (FRFE) features were extracted from each brain image. Next, we submit those(More)
BACKGROUND The need for worldwide seasonal and pandemic vaccine production has increased interest in the development of innovative technologies for influenza vaccine production. We evaluated a novel influenza vaccine consisting of the globular head of the HA1 domain of the A/Solomon Islands/3/2006 (H1N1) influenza virus (VAX125) genetically fused to the(More)
Compared with other sequenced animal genomes, human segmental duplications appear larger, more interspersed, and disproportionately represented as high-sequence identity alignments. Global sequence divergence estimates of human duplications have suggested an expansion relatively recently during hominoid evolution. Based on primate comparative sequence(More)
An computer-aided diagnosis system of pathological brain detection (PBD) is important for help physicians interpret and analyze medical images. We proposed a novel automatic PBD to distinguish pathological brains from healthy brains in magnetic resonance imaging scanning in this paper. The proposed method simplified the PBD problem to a binary(More)
