Research ArticleOpen accessIn the abstractSuppression of Salicylic Acid-Mediated Plant Defense Responses During Initial Infection of Dyer's Woad by Puccinia thlaspeosBradley R. Kropp, Elizabeth ThomasProblem statement: Puccinia thlaspeos is a microcyclic rust pathogen that is being investigated as a potential biocontrol agent of the noxious weed, dyer’s woad (Isatis tinctoria). Although, the initial events in the colonization of dyer’s woad by the rust pathogen has been elucidated using scanning electron microscopy and PCR, little is known regarding the susceptibility response of this plant to … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 3 · 4 Aug 2011 · 8,033 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntibiotic Susceptibility and Immunomodulatory Potential of Chosen Bacterial PathogensM. Sujatha, P. Dhasarathan, B. KarthickProblem statement: Antibiotic susceptibility is still the best way for bacterial pathogen escape mechanism against immunity. Approach: In the present investigation, bacterial pathogens like Staphylococcus aureus, Escherichia coli, Aeromonas hydrophila, Klebsiella and Pseudomonas aeruginosa were used to screen antibiotic susceptibility and immunomodulatory potential. Results: All the test pathogens were sensitive to all the test antibiotics 11±2 mm) except penicillin. The … …American Journal of Immunology, Vol. 6, Issue 2 · 30 Jun 2010 · 7,829 accessesView PDFCite
Research ArticleOpen accessIn the abstractMast Cells Inhibit CD8+ T Cell-Mediated Rejection of a Malignant Fibrous Histiocytoma-Like Tumor: Involvement of Fas-Fas Ligand AxisHiroshi Furukawa, Hiroshi Kitazawa, Izumi Kaneko et al.Problem statement: Mast cells develop from bone marrow-derived progenitor cells and are distributed in the skin or mucosa where they play proinflammatory roles in the first line of defense. Since some tumors in humans and experimental animals exhibited infiltration of increased mast cells, we investigated the contribution of mast cells to the override of tumor rejection. Approach: MRL/N-1 cells are … …American Journal of Immunology, Vol. 5, Issue 3 · 30 Sep 2009 · 7,670 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Supervirulence Plasmid pToK47 from Agrobacterium tumefaciens A281 Improves Transformation Efficiency of Hevea brasiliensisP. Arokiaraj, R. Leelawathy, H. Y. YeangProblem statement: The present study investigates the ability of the pTok47 supervirulence plasmid form Agrobacterium tumefaciens A281 to enhance genetic transformation in Hevea brasiliensis. Approach: Hevea anther callus was transformed via Agrobacterium-mediated genetic transformation using two strains of Agrobacterium (GV2260 and GV3850) harboring the human serum albumin cDNA and the supervirulent plasmid pToK47 from Agrobacterium tumefaciens A281. The transformed callus … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 3 · 30 Sep 2009 · 8,920 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Role of Treg Cells in the Cancer Immunological ResponseZhi-Zhang Yang, Stephen M. AnsellProblem statement: T cell-mediated immunosuppression has been observed for decades without clarification as to which factor was responsible for this observation. The identification of CD4+CD25+ regulatory T (Treg) cells represents a milestone in the filed of immunology and provides an explanation for T-cell-mediated immunosuppression. Although Treg cells were originally identified for their ability to prevent organ-specific autoimmune disease in mice, … …American Journal of Immunology, Vol. 5, Issue 1 · 31 Mar 2009 · 8,518 accessesView PDFCite
Research ArticleOpen accessIn the abstractPlasmid Mediated Tolerance and Removal of Heavy Metals by Enterobacter spBahig El-DeebProblem statement: The role of plasmid in the heavy metal resistance and accumulation by endophytic bacteria was investigated. Approach: The experimental results showed that high level plasmid mediated Cd2+ and Zn2+ resistance in this strain is due to decreased Cd2+ and/or Zn2+ uptake/accumulation by resistance strain. Results: Based on the fact that subsequent plasmid curing experiments demonstrated that the ability … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 1 · 31 Mar 2009 · 8,001 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Sorghum Density As Affected By Two Water Qualities Under Drip Irrigation SystemB.A. Ould Ahmed, T. Yamamoto, M. Inoue, H. DehghanisanijPot experiment was conducted under glasshouse conditions during 2005 at the Arid Land Research Center, Tottori University in Tottori, Japan. The study presented here was aimed to evaluating the response of sorghum (Sorghum bicolor (L) Moench), density under two different water qualities. The investigation was carried out in randomized complete block design experiments located in a plastic greenhouse. Crop growth … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 6,548 accessesView PDFCite
Research ArticleOpen accessIn the abstractCortisol Response Mediates HIV-1-Related Cognitive Deficits Among Injecting Drug AbusersRaymond L. Ownby, Drenna Waldrop-Valverde, Adarsh M. Kumar et al.The cortisol response is an important measure of the endocrine activity to environmental challenges and has been related to cognitive function and mood. Previous studies have shown that the cortisol response to stress is dysregulated in persons with HIV-1 infection. Since cortisol is neurotoxic and its levels have been related to cognitive dysfunction in various disorders, it is possible that … …American Journal of Infectious Diseases, Vol. 2, Issue 2 · 30 Jun 2006 · 6,759 accessesView PDFCite
Research ArticleOpen accessIn the abstractEarly Cellular Responses of Purine Nucleoside-mediated Protection of Hypoxia-induced Injuries of Neuronal PC12 CellsBettina Tomaselli, Valerie Podhraski, Günther Böck, Gabriele Baier-BitterlichHypoxia in brain may lead to cell death by apoptosis and necrosis. In parallel adenosine, a powerful endogenous neuroprotectant is formed. We wanted to investigate the effect of adenosine and its purine nucleoside relatives, inosine and guanosine on early cellular responses to hypoxia. O2-sensitive neuronal PC12-cells were subjected to chemical hypoxia induced with rotenone, an inhibitor of mitochondrial complex I. … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 3 · 30 Sep 2005 · 6,853 accessesView PDFCite
