Proteome-scale protein interaction maps are available for many organisms, ranging from bacteria, yeast, worms and flies to humans. These maps provide substantial new insights into systems biology, disease research and drug discovery. However, only a small fraction of the total number of human protein-protein interactions has been identified. In this study,(More)
Dengue virus is responsible for approximately 50-100 million infections, resulting in nearly 24,000 deaths annually. The capsid (C) protein of dengue virus is essential for specific encapsidation of the RNA genome, but little structural information on the C protein is available. We report the solution structure of the 200-residue homodimer of dengue 2 C(More)
Radiolabeled peptides hold promise as diagnostic/therapeutic targeting vectors for specific human cancers. We report the design and development of a targeting vector, [(64)Cu-NOTA-8-Aoc-BBN(7-14)NH(2)] (NOTA = 1,4,7-triazacyclononane-1,4,7-triacetic acid, 8-Aoc = 8-aminooctanoic acid, and BBN = bombesin), having very high selectivity and affinity for the(More)
Screening interesting biocatalysts directly from soil samples is a more convenient and applicable approach than conventional cultivation-dependent ones. In our present work, a soil-derived metagenomic library containing 24,000 transformants was constructed with an efficient strategy for cloning xylanase genes. A gene encoding the enzyme (XynH) able to(More)
The capsid proteins of two flaviviruses, yellow fever virus and dengue virus, were expressed in Escherichia coli and purified to near homogeneity suitable for biochemical characterization and structure determination by nuclear magnetic resonance. The oligomeric properties of the capsid protein in solution were investigated. In the absence of nucleic acid,(More)
BACKGROUND Less invasive surfactant administration (LISA) to spontaneously breathing preterm infants has been reported to reduce the duration of mechanical ventilation and the incidence of bronchopulmonary dysplasia (BPD) in previous study. The objective of this study was to explore the feasibility and potential benefits of LISA in early preterm infants on(More)
A rapid site-directed mutagenesis strategy using homologous recombination and DpnI digestion of the template in Escherichia coli is described. Briefly, inverse polymerase chain reaction amplification of the entire circular plasmid was performed by mutagenic primers with overlapping sequences ( approximately 15 bp) for generating PCR products with(More)
Resveratrol is a natural phytophenol that exhibits cardioprotective effects. This study was designed to elucidate the mechanisms by which resveratrol protects against diabetes-induced cardiac dysfunction. Normal control (m-Lepr(db)) mice and type 2 diabetic (Lepr(db)) mice were treated with resveratrol orally for 4 wk. In vivo MRI showed that resveratrol(More)
A novel, high-level expression, thermostable mannan endo-1,4-beta-mannosidase is urgently needed for industrial applications. The mannan endo-1,4-β-mannosidase gene (MAN) from Aspergillus niger CBS 513.88 was optimized based on the codon usage bias in Pichia pastoris and synthesized by overlapping PCR to produce MAN-P. It was expressed in P. pastoris GS115(More)
BACKGROUND Traditional Chinese Medicine (TCM) is widely used for cancer treatment in China. Many support its use in treatment for cancer, yet scientific evidence for the effect of TCM needs to be established. MATERIAL AND METHODS In this review case reports on cancer patients treated by TCM therapies are included. Search runs were conducted in 4 main(More)
