Journal of Immunobiology (Hilaris Publishing S.L) has announced almost 50% discount on article processing charge to commemorate its 10th Anniversary.
Journal of Immunobiology is an open access, peer-reviewed journal that focuses and welcomes submissions on all aspects of Immunobiology, Immunology, Autoimmunity, Innate Immunity, Adaptive Immunity, immunization, Immunogenetics, Immune Disorders, Immunodeficiency, Immune inflammation, Immunoinformatics, Clinical Immunology, Allergy & Immunology, Clinical & Vaccine Immunology, Inflammatory Disorders, Autoimmune Disorders, Immunotherapy and Immunopathology of infectious, allergic and autoimmune disease etc.
It gives us great pleasure to announce the call for paper on the occasion of 10th Anniversary of the Journal at special and hefty discount of up to 50 % on one-time article processing charge. Prospective academicians and scientists are encouraged to utilize this opportunity to get their articles reviewed, processed and published at relatively faster pace and at lower charges. In addition to this, the authors who publish with us during the year-long celebrations will also be eligible for academic awards recommended by the editorial panel.
The Archive page contains wide variety of articles such as Research / Review / Case reports / short communication / Mini review / Prospective / Letter to Editors Etc. We would like introduce a Research article which has been spread to the widest audience of experts; and thus increased in readership, citations and altimetry score.
Abstract: Absolute and percentage CD4+ T-lymphocytes counts are useful in monitoring people living with HIV. In spite of point-of-care development, CD4 testing in some laboratories of resources-limited countries still use flow cytometers from many manufacturers. We evaluated three flow cytometers (FACSCOUNT CD4/CD4%, GUAVA Auto CD4/CD4%, CYFLOW Counter® CD4/CD4%) and brought out choice criteria according to laboratory resources. CD4 percent and absolute count obtained with 180 HIV-infected patients (adults and children) with evaluated platforms (FACSCOUNT CD4/CD4%, GUAVA Auto CD4/CD4%, CYFLOW Counter CD4/CD4%) were compared with those provided by FACSCalibur TruCount®. Agreement was analyzed using Bland-Altman analysis. We also carried out a Comparative analysis of technical and operational characteristics to identify strengths and weaknesses of each tested cytometer. The median CD4 percentage and absolute count obtained with FACSCOUNT and CYFLOW were similar to those of FACSCALIBUR. By contrast, GUAVA showed higher values. Bland-Altman analysis did not show measurement error. However, GUAVA and CYFLOW gave a relative high bias with mean difference respectively -69 and +27CD4 cells/μl. The overall bias of CD4 percentage were >5% for the evaluated cytometers. There was a good interclass agreement (Kappa ≥ 0.78) and good measurement precision (coefficient of variation <10%) with the 3 cytometers. Only FACSCOUNT showed good stability (CV<5%) even for stained and unstained samples within 24 and 48 hours after blood collection. FACSCOUNT, GUAVA and CYFLOW have good technical performances. Though we found differences in their operational characteristics, it appears very important to know how to use these kinds of cytometers before making a choice for peripheral laboratory in limited-resources countries.
