Research ArticleOpen accessIn the abstractTherapeutic Effects of Phyllanthus Species: Induction of TNF-α-mediated Apoptosis in HepG2 Hepatocellular Carcinoma CellsSripathi M. Sureban, Dharmalingam Subramaniam, Paramasivam Rajendran et al.Phyllanthus species, especially P. amarus is a medicinal plant with hepatoprotective activity, believed to occur in part by inhibiting hepatitis B virus function. The pathogenesis mechanism of viral hepatitis is closely related to hepatocyte necrosis apoptosis. The aim of our study was to investigate the in vitro effects of extracts from three Phyllanthus species, P. urinaria, P. amarus and P. … …American Journal of Pharmacology and Toxicology, Vol. 1, Issue 4 · 31 Dec 2007 · 9,009 accessesView PDF Cite

Research ArticleOpen accessIn the abstractInduction of a Soluble Anti-HIV-1 factor (s) with IFN-γ, IL-10, and β-Chemokine Modulating Activity by an Influenza-Bacterial Polyantigenic MixtureJosé W. Rodríguez, Nat O. Pagan, Mar C. Ocasio et al.Partial immune restoration may be obtained with highly active antiretroviral therapy (HAART), but specific anti-HIV-1 immune responses do not appear to improve substantially. We have demonstrated that a soluble factor(s) induced by a mixture of inactivated influenza and bacterial vaccines called polyantigenic immunomodulator (PAI), possesses strong immunoregulatory and anti- HIV-1 activities. In the present study, we show that culture fluids … …American Journal of Infectious Diseases, Vol. 3, Issue 4 · 31 Dec 2007 · 6,850 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSuppression of Basal and Cytokine Induced Expression of MHC, ICAM 1 and B7 Markers on Mouse Lung Epithelial Cells Exposed to Diesel Exhaust ParticlesRajiv K. Saxena, Wanda Williams, M. Ian GilmourDiesel exhaust particles (DEP) constitute a significant component of airborne particulates in urban environment. Exposure to DEP is known to enhance susceptibility to viral and bacterial infections. We hypothesized that DEP could partially exert its effect on disease susceptibility by interfering with antigen presentation required for the generation of protective adaptive immune responses. MHC class I and class II molecules, … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 4 · 31 Dec 2007 · 6,610 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEmpirical Analysis: Business Cycles and Inward FDI in ChinaQiyun Fang, Yao LiuIt is well-known that the current speeding-up of globalization has been, on one hand, spreading macro economic effects around the world, while, on the other, fueling firms' activities of crossing national borders. Then, are there any links between these two influences? In this paper, we chose China as our subject, to try to clarify it. A set of models for … …American Journal of Applied Sciences, Vol. 4, Issue 10 · 31 Oct 2007 · 6,836 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDeciding Whether There is Statistical Independence or Not?Ramzi NasserThe study investigated how students assess statistical independence (SI). A sample of 98 students was available to the researcher. One group was probed on their understanding of statistical independence, a second group was given a proficiency test and a third group was presented a proof for statistical Independence. Interview data from the first two groups exposed student misconception on their … …Journal of Mathematics and Statistics, Vol. 3, Issue 3 · 30 Sep 2007 · 6,822 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEvaluation of the Upland Weed Control Potentiality of Green Tea Waste-Rice Bran Compost and Its Effect on Spinach GrowthM.A.I. Khan, K. Ueno, S. Horimoto et al.This study evaluated the upland weed control potentiality, germination inhibition ability and growth suppression efficiency of the five combinations of green tea waste - rice bran compost (GRC). GRC was prepared by mixing green tea waste and rice bran at five ratios, and allowed to decompose for 5 mo. Application of GRC suppressed weed growth up to 93.4% in number … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 3 · 30 Sep 2007 · 8,207 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEvaluation of a DNA Vaccine for Immunocontraceptive Potential Against Zona Pellucida Glycoproteins in CattleC.A. Foley, S.M. Boyle, R.E. Pearson, F.C. GwazdauskasHolstein cows were administered zona pellucida (ZP) DNA vaccine and used to determine the potential of recombinant rabbit ZP glycoproteins (rZP) as immunocontraceptive antigens. Zona pellucida proteins were purified and quantified. Cows were assigned to one of four treatment groups in which plasmids encoding rabbit ZP proteins were administered, i.d., using a gene gun (ZP55, n=2; ZP75, n=2; Hep55, n=2; … …American Journal of Animal and Veterinary Sciences, Vol. 2, Issue 1 · 31 Mar 2007 · 6,890 accessesView PDF Cite

Research ArticleOpen accessIn the abstractImmunological Evidence for Peptide-Carbohydrate Mimicry with a Group A Streptococcus Polysaccharide-Mimetic PeptideSilvia Borrelli, Rehana B. Hossany, Susan Findlay, B. Mario PintoThe immunogenicity of a peptide-protein conjugate developed by linking a peptide mimic DRPVPY of the Group A Streptococcus cell-wall polysaccharide (GAS-CWPS), to tetanus toxoid (TT) was examined. BALB/c mice were immunized three times subcutaneously following homologous or heterologous prime/boost strategies at 4- or 6- week intervals in two different experiments. DRPVPY-TT, CWPS-TT, heat-killed, pepsin-treated GAS bacteria (with exposed polysaccharide) and … …American Journal of Immunology, Vol. 2, Issue 4 · 31 Dec 2006 · 6,960 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUpgrading of Light Dewaxed Oil through Hydrofinishing and Additives Blending for Producing Automatic Transmission FluidGamal Abdel-Nasser Gohar, Mohamed Sherif El-Gayar, Abd El-Moneim Ibrahim et al.Light dewaxed oil was produced through dewaxing process of the light waxy distillate raffinate of crude oil from Western Desert of Egypt using methyl ethyl ketone/toluene mixed solvent. Hydrofinishing process was used to remove the non-hydrocarbon constituents and to improve the physicochemical properties of the produced oils such as color, viscosity index, inhibition responses, oxidation and thermal stability. The operating … …American Journal of Applied Sciences, Vol. 3, Issue 12 · 31 Dec 2006 · 6,982 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDC Motor Control Predictive ModelsRavinesh Singh, Godfrey C. Onwubolu, Krishnileshwar Singh, Ritnesh RamDC motor speed and position controls are fundamental in vehicles in general and robotics in particular. This study presents a mathematical model for correlating the interactions of some DC motor control parameters such as duty cycle, terminal voltage, frequency and load on some responses such as output current, voltage and speed by means of response surface methodology. For this exercise, … …American Journal of Applied Sciences, Vol. 3, Issue 11 · 30 Nov 2006 · 7,019 accessesView PDF Cite
