Comparisons of the relative activities of 11 intergenic region (IGR) internal ribosome entry site (IRES) elements of insect dicistrovirus with 5' IRES elements of the hepatitis C and encephalomyocarditis viruses were performed in insect and mammalian cells. Dual luciferase assays were performed to determine the most effective dicistrovirus IGR IRES in the lepidopteran cell lines Sf9 (Spodoptera...

Muscle sarcomeres contain giant polypeptides composed of multiple immunoglobulin and fibronectin domains and one or two protein kinase domains. Although binding partners for a number of this family's kinase domains have been identified, the catalytic necessity of these kinase domains remains unknown. In addition, various members of this kinase family are suspected pseudokinases with no or littl...

For an indoor non-directed line of sight optical wireless communication (NLOS-OWC) system we investigate the optimized Lambertian order (OLO) of light-emitting diodes (LEDs). We firstly derive an expression for the OLO from a conventional Lambertian LED model. Then, we analyze the indoor multi-cell NLOS-OWC channel characteristics including the optical power distribution and the multipath time ...

Background: The importance of viral protein-2 (VP2) of canine parvovirus (CPV) in binding to human cancer cells, production of veterinary vaccines and diagnostic kits has motivated several researches on producing this protein.Objectives: Our purpose was to construct recombinant bacmid shuttle vectors expressing VP2 of CPV using Bac-to-Bac baculoviral expr...

Numerous studies have shown the positive effects of rosmarinic acid on the nervous system. Rosmarinic acid as a herbal compound with anti-inflammatory effects can prevent the destructive effect of inflammation on the nervous system. Furthermore, various studies have emphasized the advantages of three dimensional (3D) culture over the two dimensional (2D) culture of cells. In this study, thermos...

Characterization and evaluation of the activity of Vespa basalis DPP-IV, which expressed in Spodoptera frugiperda 21 cells. The expression of rDPP-IV was confirmed by SDS–PAGE, Western blot analyses, LC-MS/MS and measurement of its peptidase specificity. One-step purification by Ni-NTA affinity chromatography and the total amount of rDPP-IV recovered was approximately 6.4mg per liter from infec...

The melanoma differentiation associated gene-7 (mda-7), also known as interleukin-24 (IL-24) is a novel cytokine, which exhibits both tumor suppressing and immunostimulatory activities. Mda-7 has the ability to restrain growth and induce programmed cell death (apoptosis) in a wide variety of human cancer cells without having similar effects on normal cells. This study was performed to investiga...

OBJECTIVE Porcine circovirus type 2 (PCV2) is the causative agent of postweaning multisystemic syndrome in pigs. The capsid (Cap) protein encoded by ORF2 is the main structural protein involved in the host immune protective response to PCV2. It is therefore important to map the antigenic epitopes of the PCV2 Cap protein. METHODS In this study, 5 monoclonal antibodies (mAbs) against the recomb...
