Research ArticleOpen accessIn the keywordsThe Tumor/Immune Interface: Clinical Evidence of Cancer Immunosurveillance, Immunoediting and ImmunosubversionMatthew S. Block, Svetomir N. MarkovicProblem statement: The interactions of a malignant tumor with the patient’s immune system are dynamic, multiple and bi-directional. Approach: This article reviews the clinical evidence of the interaction of cancer with immunity with emphasis on recent developments highlighting some of the mechanisms of tumor-mediated regulation of immunity. Results: Most of the time, the immune response to a malignancy acts to … …American Journal of Immunology, Vol. 5, Issue 1 · 31 Mar 2009 · 10,095 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsSoluble CD14, Sialic Acid and L-Fucose in Breast Milk and their Role in Increasing the Immunity of Breast-Fed InfantsGhalib Ali Oriquat, Tahia H. Saleem, Samir T. Abdullah et al.Problem statement: Breast milk contain protective factors as soluble CD14, L-Fucose and Sialic acid which increase the innate immunity and level of intelligence, decrease the incidence of gastroenteritis, chest and other systemic diseases in newly born infants. In the present study the role of soluble CD14, L-Fucose and Sialic acid, in increasing the immunity in breastfed infants were studied to … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 1 · 27 Apr 2011 · 10,188 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsHepatitis B Diagnosis Using Logical Inference and Self-Organizing MapGhumbre Shashikant Uttreshwar, A.A. GhatolDespite all the standardization efforts made, medical diagnosis is still regarded as an art owing to the fact that that medical diagnosis requires an expertise in handling the uncertainty which is unavailable in today's computing machinery. Though artificial intelligence is not a new concept it has been widely recognized as a new technology in computer science. Numerous areas such as … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Dec 2008 · 6,874 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsUltrastructural and Immunological Characterization of Hepatitis C Core Protein-DNA Plasmid ComplexesNelson Acosta-Rivero, Yaraima Aguilera, Viviana Falcon et al.Recently, it has been shown that a truncated HCV core (HCcAg) variant, covering the first 120 aa (HCcAg.120), interacts with plasmid DNA vaccine (pIDKE2), encoding the HCV structural proteins (HCcAg, E1 and E2). In the present work, HCcAg.120-pIDKE2 complexes, forming heterogeneous packaged structures, were visualized using a negative stain/rotary shadow technique. Interestingly, 72 hours after intramuscular injection of HCcAg.120-pIDKE2 complexes … …American Journal of Immunology, Vol. 2, Issue 3 · 30 Sep 2006 · 6,743 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsInteraction of a C-terminal Truncated Hepatitis C Virus Core Protein with Plasmid DNA Vaccine Leads to in vitro Assembly of Heterogeneous Virus-like ParticlesNelson Acosta-Rivero, Joanna Poutou, Alexis Mussachio et al.Recently, it has been shown that HCV core proteins (HCcAg) with C-terminal deletions assemble in vitro into virus-like particles (VLPs) in the presence of structured RNA molecules. Results presented in this work showed that a truncated HCcAg variant covering the first 120 aa (HCcAg.120) with a 32 aa N-terminal fusion peptide (6xHistag-XpressTMepitope) interacts with plasmid DNA vaccine. Interestingly, the buoyant … …American Journal of Infectious Diseases, Vol. 1, Issue 1 · 31 Mar 2005 · 6,754 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsHIV-1-Specific CTL Recognizing a Scarce Epitope Are Not Suppressed by HIV-1 Protease InhibitorsOtto O. YangHIV-1-protease inhibitors have received growing attention as agents that can affect proteases in human proteasomes, with potentially deleterious effects for HIV-1-specific cellular immunity. Studying the antiviral activity of HIV-1-specific CTL that recognize an epitope that is presented at limiting concentrations on infected cells, we find that several HIV-1 protease inhibitors do not affect their function. These data indicate that these … …American Journal of Immunology, Vol. 3, Issue 1 · 30 Jun 2007 · 7,016 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEpigenetic Regulation of Extracellular Matrix Remodeling in Skin Aging: Mechanisms and InteractionsJiguang Yang, Yusong Shi, Xiaoqing YanSkin aging results from complex interactions between genetic factors, environmental stressors, and epigenetic modifications that regulate extracellular matrix (ECM) remodeling. Accumulation of senescent cells impairs tissue regeneration through mechanisms including telomere shortening, reactive oxygen species accumulation, and ultraviolet (UV) radiation exposure. While epigenetic pathways regulate skin homeostasis, regeneration, and senescence, the specific epigenetic changes occurring during UV exposure, chronological aging, … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 4 · 15 Feb 2026 · 1,458 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAnalysis of the Utility of MPT64, Drug Susceptibility Testing and Tuberculosis/Nontuberculous Mycobacteria Reverse Transcription Polymerase Chain Reaction for Tuberculosis Diagnosis and Efficiency Compared with Traditional CultureHo Keun Choi, Ga Yeon Kim, Tae Soung Kim, Jae Kyung KimDefining the molecular mechanisms underlying the dormant state of Mycobacterium tuberculosis (MTB) is essential for developing more effective treatments for tuberculosis (TB) infection. We investigated the positivity and resistance rates of TB tests on 6,174 samples referred to a single hospital. Of these, 342 cases (5.5%) were confirmed as positive by acid-fast bacilli staining, 243 cases (71.1%) were detected as … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 4 · 5 Dec 2024 · 4,206 accessesView PDF Cite
