Research ArticleOpen accessIn the abstractPerformance of Pre-Weaned Dairy Calves under Hot Arid Environment: Effects of Immunoglobulins and Age on Diseases and MortalityM. A. Razzaque, T. Al-Mutawa, S. Abbas, M. BedairProblem statement: A high mortality rate (crude mortality 43.6%) of pre-weaned dairy calves resulted in unavailability of replacement heifers in Kuwait. Dairy producers resorted to import pregnant heifers for herd replacement. This study was undertaken to investigate the effects of dam vaccination and age, serum Immunoglobulin (Ig) on disease syndromes and mortality in pre-weaned calves. Approach: Late pregnant Holstein Friesian … …American Journal of Applied Sciences, Vol. 6, Issue 11 · 30 Nov 2009 · 7,560 accessesView PDFCite
Research ArticleOpen accessIn the abstractImmunomodulatory and In vivo Antiplasmodial Activities of Propolis ExtractsSyamsudin, Rita Marleta Dewi, KusmardiProblem statement: Malaria caused by various species of prozoan parasites, Plasmodium. The exact mechanism of humoral immunity in eliminating Plasmodium is not completely understood. However, an antimalarial antibody is strongly suspected to play important role in immunity. The purpose of this research was to evaluate the immunomodulator and antiplasmodial activities of Indonesian propolis extracts. Approach: Thirty male BALB/c mice weighing … …American Journal of Pharmacology and Toxicology, Vol. 4, Issue 3 · 30 Sep 2009 · 7,802 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe 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 · 10,100 accessesView PDFCite
Research ArticleOpen accessIn the abstractCancer Chemotherapy and Immune RegulationJohn Barrett, Katarina Le BlancProblem statement: Chemotherapeutic drugs have been used to treat malignancy for over 50 years, but the potential of cytotoxic agents to suppress immunity and interfere with Immunosurveillance (IS) of cancer has been largely ignored. Assuming that the immune control of the cancer had a priori already failed, the effect was not considered to have a major impact on treatment outcome. … …American Journal of Immunology, Vol. 5, Issue 1 · 31 Mar 2009 · 40,670 accessesView PDFCite
Research ArticleOpen accessIn the abstractHormetic Triggers for Intervention in Aging, Disease and TraumaJoan Smith SonnebornHormesis refers to the ability of a chemical or physical agent to condition the physiological state of an organism to tolerate stress with low doses of otherwise harmful agents. Evolutionary evidence shows that the survival and longevity of species hinge on their optimal ability to resist stress challenge. Hormesis is a potent strategy to stimulate latent repair processes to tolerate … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 7,898 accessesView PDFCite
Research ArticleOpen accessIn the abstractDiagnosis of Hepatitis Disease with Logistic Regression and Artificial Neural NetworksAlaa M. Elsayad, Ahmed M. Nassef, Mujahed Al-DhaifallahHepatitis C refers to the inflammatory state of the liver caused by viruses, bacteria, fungi, and exposure to toxins such as alcohol and self-immunity. The diagnosis requires investigating many laboratory tests and comparing the results to those of the former patients with the same conditions. This study presents the results of our experiments to build a hybrid system that combines … …Journal of Computer Science, Vol. 16, Issue 3 · 27 Mar 2020 · 7,470 accessesView PDFCite
Research ArticleOpen accessIn the abstractDoes Iron Modulate Cytokine Production by Desferrioxamine Treated Mononuclear Cells?Hanna Bessler, Meir DjaldettiIron is an essential element for maintaining the normal function of cellular and multicellular organisms and it is closely associated with inflammation and immunity. Macrophages and lymphocytes play an important role in its homeostasis. Hereby we have evaluated cytokine production by iron depleted and iron supplemented human peripheral blood mononuclear cells (PBMC) from healthy adult donors. Non-stimulated or stimulated PBMC … …OnLine Journal of Biological Sciences, Vol. 18, Issue 1 · 7 Jan 2018 · 6,849 accessesView PDFCite
Review ArticleOpen accessIn the abstractThe Triple Immune Argument; Surveillance/Evasion/ Senescence and the Increased Incidence of Acute Myeloid Leukemia Observed with AgeManar M. IsmailAML originates from genetic insults of hematopoietic stem and progenitor cells (HSPCs/HSCs) that was identified earlier as leukemia stem cells (LSCs). In quiescent state, trafficking immune cells are crucial for eradication of aberrant clones and obtaining balance between proliferation and apoptosis to maintain HSCs pool. Regulatory T-cells shield the HSCs from the inflammatory reactions by suppressing T- and B- cells. … …American Journal of Immunology, Vol. 13, Issue 4 · 22 Dec 2017 · 7,807 accessesView PDFCite
Research ArticleOpen accessIn the abstractHumoral and Cellular Effects of Stress-An Extensive Model SystemMazal Shimon-Hophy, Ramy R. AvtalionThe influence of stress on the immune system of the common carp (Cyprinus carpio) was studied by measuring leukocytes levels using flow cytometry and mRNA immune components by real time qPCR. Acute and chronic oxidative stresses were generated by different regimes of exposure of carp to environmental air. In acute stress, induced by single air exposure, the pro-inflammatory cytokines (IL1β, … …American Journal of Immunology, Vol. 13, Issue 2 · 18 Apr 2017 · 6,728 accessesView PDFCite
Research ArticleOpen accessIn the abstractβ-Glucan in AllergiesSima Petr, Vetvicka VaclavMultiple effects of β-glucan are well established. Together with the effects on antibacterial and anticancer immunity, glucan has been shown to stimulate bone marrow cells, lower cholesterol and to protects against stress and some kinds of poisoning. However, despite literally thousands of papers describing biological effects of β-glucan, only limited attention has been focused on the role of β-glucan in … …American Journal of Immunology, Vol. 13, Issue 1 · 30 Mar 2017 · 8,985 accessesView PDFCite
