objective(s) portulaca oleracea l. is a herbaceous weed from portulacaceae family. it can be found in many parts of the world. modern pharmacological studies have demonstrated that p. oleracea have antioxidant effects. the protective effect of aqueous and ethanolic extract of p. oleracea against cisplatin-induced renal toxicity was studied in rats. materials and methods single intraperitoneal i...

• Pristine CaTiO 3 has no activity for SCR deNO x , while Ce-Fe-Mn doped could achieve almost 100% NO conversion at 135°C (GHSV = 72000 h -1 ). By selectively activating gaseous molecules, Ti, Fe, and Mn present apparent synergistic effects on accelerating the catalytic cycle of standard SCR. The photocarriers intensify oxidation rather than NH -to-NH 2 transformation. Although photocatalysis e...

A number of genetic interactions are involved in the control of cell cycle, but their role and nature have not been completely clarified. The knowledge of the behavior of these interactions in hepatocellular carcinoma, could optimize preventive and therapeutic strategies based on cell cycle restraint. We studied downstream events following c-MYC and CYCLIN D1 gene inhibition, by lipoplex-delive...

Macroeconomic forecasts are often based on the interaction between econometric models and experts. A forecast that is based only on an econometric model is replicable and may be unbiased, whereas a forecast that is not based only on an econometric model, but also incorporates an expert's touch, is non-replicable and is typically biased. In this paper we propose a methodology to analyze the qual...

Virus-induced changes in cellular gene expression and host physiology have been studied extensively. Still, there are only a few analyses covering the entire viral replication cycle and whole-host gene pool expression at the resolution of a single gene. Here we report changes in Escherichia coli gene expression during bacteriophage PRD1 infection using microarray technology. Relative mRNA level...

Knowledge about the protein composition of phage virions is a key step to understand the functions of phage virion proteins. However, the experimental method to identify virion proteins is time consuming and expensive. Thus, it is highly desirable to develop novel computational methods for phage virion protein identification. In this study, a Naïve Bayes based method was proposed to predict pha...

Retroviruses contain two complete viral genomic RNAs in each virion. A system to study in a single round of replication the products of virions with two different genomic RNAs was established. A spleen necrosis virus-based splicing vector containing both the neomycin-resistance gene (neo) and the hygromycin B phosphotransferase gene (hygro) was used. Two frameshift mutants were derived from thi...
