ABSTRACT Background & Objectives: Helicobacter pylori is a gram negative, microaerophilic and flagellated bacillus, which causes digestive diseases, such as peptic ulcer and gastric cancer. This study aimed to detect Helicobacter pylori in patients with ulcer disease through stool antigen and serological tests in Sari, Iran. Materials and Methods: In this study, 120 patients (aged 15-66 yea...
hepatitis b surface antigen is the first genetically engineered vaccine licensed for human use. various strategies have been proposed to obtain a vaccine that would bypass the need for injection. in this study, a non-toxic portion of heat-stable enterotoxin of escherichia coli that is capable of adhering to epithelial cells was inserted at amino acid position 112 of hepatitis surface antigen. t...
background: different studies have demonstrated that a small proportion of healthy individuals receiving the hepatitis b (hb) vaccine do not produce protective levels of anti-hb antibody, a phenomenon which could be linked to certain human leukocyte an-tigen (hla) class-ii alleles or haplotypes. objectives: the present study was under-taken to determine the frequency of hla class-ii alleles in ...
conclusions based on our study, in vivo prepared e/sa may be considered as a good candidate for animal immunization. results our results showed that the serum levels of anti-e/sa immunoglobulins significantly increased in all of the immunized groups. the differences of the serum levels of tgf-β between the groups were statistically significant at days 28 and 56 after immunization with e/sa. bac...
مقدمه: نقص ایمنی متغیر شایع (common variable immunodeficiency یا cvid)، فراوان ترین نارسایی ایمنی اولیه از نظر بروز علایم بالینی و مجموعه شرایط ناهمگنی است که با کمبود ارثی آنتی بادی (هایپوگاماگلوبولینمی) از حداقل دو ایزوتیپ ایمونوگلوبولین به همراه اختلال در بلوغ سلول های b و جهش سوماتیک، کاهش تعداد سلول های خاطره ی تعویض کلاس شده و نشده در گردش خون و اغلب با نبود پلاسماسل شناخته می شود. b-cell...
vaccines against the hiv-1 virus offers the best hope for eliminating hiv-associated mortality. recombinant adenovector type 5 (rad5) vaccine is a potential candidate for preventive vaccine strategies. in this study, we evaluated the rad5 prime/protein boost strategy in a murine model. we used rad5 harboring single hiv-1 genes. these genes, including gag (p24) and exon1 of tat, were amplified f...
background and objectives: invasive and non-invasive techniques are used to diagnose h. pylori infection. some factors influence the choice of a diagnostic test, such as the sensitivity and specificity of the tests, the clinical circumstances and the cost-effectiveness of the testing strategy. the aim of this study was to reveal the relationship between different h. pylori infection diagnosis m...
background: the sole published data on feline heartworm infection in the philippines was reported four decades ago. the study therefore endeavoured to assess and provide an update on the current status of heartworm infection in domesticated feline species using serologic and parasitological ex-amination methods. methods: a total of 46 males and 54 females cats showing clinical signs of dirofila...
background: nowadays, highly specific aptamers generated by cell selex technology (systematic evolution of ligands by exponential enrichment) are being applied for early detection of cancer cells. prostate specific membrane antigen (psma), over expressed in prostate cancer, is a highly specific marker and therefore can be used for diagnosis of the prostate cancer cells. the aim of the present s...
background: leishmaniasis is a worldwide disease prevalent in tropical and sub tropical countries. many attempts have been made and different strategies have been approached to develop a potent vaccine against leishmania . dna immunisation is a method, which is shown to be effective in leishmania vaccination. leishmania soluble antigen (sla) has also recently been used leishmania vaccination....
