Reactive oxygen species are associated with various diseases including cardiovascular diseases, neurological disorders, and pulmonary diseases. Extracellular superoxide dismutase (ECSOD) is an antioxidant enzyme secreted by cells to prevent overproduction of reactive oxygen species. We expressed an ECSOD gene isolated from a human aortic smooth muscle cDNA(More)
An important issue in critical care medicine is the identification of ways to protect the lungs from oxygen toxicity and reduce systemic oxidative stress in conditions requiring mechanical ventilation and high levels of oxygen. One way to prevent oxygen toxicity is to augment antioxidant enzyme activity in the respiratory system. The current study(More)
Epstein-Barr virus (EBV) genome-chips are employed to determine the EBV infection rate and to reveal the gene expression patterns of EBV in tumor biopsies. These chips are produced with 71 consecutive PCR-amplified EBV DNA fragments of 1-3 kbp covering the entire EBV genome. The specificity of the EBV-chips is determined by hybridizing the DNA on the chips(More)
Lactoferrin is a metal-binding glycoprotein exhibiting multifunctional immunoregulation of antibacterial, antioxidant, anti-endotoxin and antiviral activities. Uptake of porcine lactoferrin (PLF) has been shown to enhance resistance to diarrhea and anemia in neonatal piglets. In this study, the methylotrophic yeast, Pichia pastoris, was used to express a(More)
In this study, Lactobacillus casei was used to deliver and express human lactoferrin (hLF) to protect the host against bacterial infection. Full-length hLF cDNA was cloned into a Lactobacillus-specific plasmid to produce the L. casei transformants (rhLF/L. casei). Antimicrobial activity of recombinant hLF was examined in inhibition of bacteria growth in(More)
SCOPE We investigated the inhibition of pulmonary tumor formation through treatment with curcumin in transgenic mice. METHODS AND RESULTS In this study, a strain of transgenic mice carrying human vascular endothelial growth factor A₁₆₅ (hVEGF-A₁₆₅) gene to induce pulmonary tumor was used as an in vivo cancer therapy model. We found that curcumin(More)
In this study, recombinant porcine lactoferrin (PLF) was used as feedstuff additive to investigate the effects of peripheral lymphocyte proliferation and serum antibody titers in chickens vaccinated against the infectious bursal disease (IBD) virus. Treatment groups were fed three doses of PLF powder in their diet (0.5, 1.0, and 2.0% w/w), and the IBD(More)
A novel microstirring strategy is applied to accelerate the digestion rate of the substrate N(alpha)-benzoyl-L-arginine-4-nitroanilide (L-BAPA) catalyzed by sol-gel encapsulated trypsin. We use an ac nonlinear electrokinetic vortex flow to stir the solution in a microfluidic reaction chamber to reduce the diffusion length between the immobilized enzyme and(More)
Network Address Translation (NAT) causes difficulties for peer-to-peer (P2P) communication. For BitTorrent, if only one client is behind NAT, it is possible for two clients to build connection. But for both clients are behind different NATs, currently it is not possible without specific settings on their own NAT. In this work, we integrate TCP NAT traversal(More)
