Research ArticleOpen accessIn the abstractThe Changing Pathology of NeuroAIDS Associated with Drug Abuse in the Era of HAARTE Bell Jeanne, C. Anthony Iain, Simmonds PeterCompliance with highly active antiretroviral therapy (HAART) arrests HIV induced immune collapse and reduces the prevalence of severe central nervous system (CNS) complications, including HIV associated dementia and encephalitis. However minor cognitive disorders remain common and recent autopsy studies have demonstrated the presence of subtle neuropathological abnormalities in HAART treated individuals, including persistent neuroinflammation and enhanced deposition in the brain … …American Journal of Infectious Diseases, Vol. 2, Issue 2 · 30 Jun 2006 · 6,872 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of the Differential Gene Expression, by the DD-RTPCR Technique, Of Workers Atta sexdens rubropilosa Mandibular Glands (Hymenoptera: Formicidae)Lorena Favaro Pavon, Maria Izabel Camargo Mathias, Flávio Meirelles, Maurício Bacci JúniorThe DD-RTPCR technique is becoming more efficient nowadays to isolate and characterize genes differentially expressed among cells, tissues or individuals, being used here, for the first time in the study of mandibular glands of minina and media workers and soldiers of the ant species Atta sexdens rubropilosa. The expression profile of bands (transcripts), obtained in the present study, permitted the … …American Journal of Agricultural and Biological Sciences, Vol. 1, Issue 2 · 30 Jun 2006 · 7,841 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of the Mandibular Glands of Ant Workers Atta sexdens rubropilosa (Forel, 1908) (Hymenoptera: Formicidae) Focusing the Ultrastructural CytochemistryLorena Favaro Pavon, Maria Izabel Camargo MathiasThe mandibular glands of hymenopterans in general are paired structures located on each side of the head. These glands possess an excretory duct located at the internal surface of the mandible articulation, through which these glands release the secretion they produce. The mandibular glands of the minima, media and soldier worker of the ant Atta sexdens rubropilosa were analyzed by … …American Journal of Agricultural and Biological Sciences, Vol. 1, Issue 2 · 30 Jun 2006 · 7,643 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Evaluation of Implementing Calls Prioritization with Different Queuing Disciplines in Mobile Wireless NetworksSalman A. AlQahtani, Nasser-Eddine RikliIt is known that efficient call handling mechanisms can greatly improve cellular network performance. One way to improve system performance of cellular network is to use efficient handover schemes when users changes between cells. This paper focuses on the performance evaluation of originating and handover calls prioritization using different queue size and discipline. Both calls will be queued until they … …Journal of Computer Science, Vol. 2, Issue 5 · 31 May 2006 · 6,470 accessesView PDFCite
Research ArticleOpen accessIn the abstractNa,K-ATPase α Subunit-like Immunoreactive Proteins in Human Body FluidsJeng-Hsiung F. PengNa,K-ATPase was recently considered a target for breast cancer treatment since its potent inhibitors ouabain and related digitalis compounds that were reported circulating in body fluids before, were found to possess potent anti-breast cancer activity. Based on this finding, it is hypothesized that Na,K-ATPase derivatives could be circulating in the body and potential candidate biomarkers for early disease detection. Western … …American Journal of Immunology, Vol. 2, Issue 1 · 31 Mar 2006 · 6,892 accessesView PDFCite
Research ArticleOpen accessIn the abstractImmunomodulatory Treatment of Infertility in Men with Elevated Antisperm AntibodiesIvan Bubanovic, Slobodan Kojic, Stevo Najman, Zlatibor AndjelkovicPossible causes of subfertility or infertility in men are still poorly defined, but one important category may be elevated level of antisperm antibodies (ASA) caused by infective and/or autoimmune diseases, as well as injuries of male reproductive system. In this study, blood sera from 45 infertile men of different age with ASA positive ELISA test were examined for the serum … …American Journal of Immunology, Vol. 1, Issue 4 · 31 Dec 2005 · 8,839 accessesView PDFCite
Research ArticleOpen accessIn the abstractLarge Scale Production and Characterization of Anti-Human IgG Monoclonal Antibody in Peritoneum of Balb/c MICEB. Baradaran, J. Majidi, Z. M. Hassan, J. AbdolalizadehMonoclonal antibodies are key reagents that are used in biomedical researches, diagnosis of immunodeficiency diseases such as IgG subclasses deficiency and treatment of diseases like infections and cancers. For large scale production of monoclonal antibody, hybridoma cells that produce monoclonal antibody against human IgG were injected into the peritoneum of the Balb/c mice which have previously been primed with 0.5 … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 4 · 31 Dec 2005 · 7,089 accessesView PDFCite
Research ArticleOpen accessIn the abstractSoluble Tumor Necrosis Factor Receptor Type I and Dranulysin as Immunological Markers in Congestive Heart FailureSimone de Lima e Silva Deo, Maria Do Carmo Valente De Crasto, Alda Maria Da-Cruz et al.Previous studies have shown that circulating levels of cytokines are increased in patients with congestive heart failure (CHF), resulting in myocardial depression. In this work, we have determined serum levels of TNF-α and IFN-γ by ELISA, detected sTNFR-I by dot ELISA, as well as TNFα, IL-6, IL-10 and granulysin mRNA in unstimulated peripheral blood mononuclear cells (PBMC) by RT-PCR in … …American Journal of Immunology, Vol. 1, Issue 3 · 30 Sep 2005 · 6,773 accessesView PDFCite
Research ArticleOpen accessIn the abstractTowards Identifying Immunogenic Targets in Visceral Leishmaniasis: Role of 17kDa and 63kDa PhosphoproteinsShubhankar K Singh, Sanjiva Bimal, Diwakar S. Dinesh et al.We observed predominant phosphorylation at Protein Kinase C (PKC-α) residue in seven immunoreactive proteins of virulent Leishmania donovani parasites. These phosphoproteins were tested for their ability to stimulate T-cells for secretion of Macrophage Migration Inhibition Factor (MIF) in comparision to crude soluble antigen in Visceral Leishmaniasis (VL) patients. Two of these phosphorylated L. donovani antigens led Leishmania to present these … …American Journal of Immunology, Vol. 1, Issue 3 · 30 Sep 2005 · 6,756 accessesView PDFCite
Research ArticleOpen accessIn the abstractHumoral Immune Response in Tuberculous PleuritisPrabha C., Kripa V. Jalapathy, Sulochana D. DasTuberculous pleuritis is a good human model to understand the local and protective immune response against tuberculosis, due to the self-limitedness of the disease. Although the cellular immune response has been well characterised in tuberculous pleurisy, much less is known about the humoral immune response operating at the site of infection. To understand the humoral immune response, B cells were … …American Journal of Immunology, Vol. 1, Issue 2 · 30 Jun 2005 · 6,518 accessesView PDFCite
