abstract background a vast variety of factors may cause recurrent pregnancy loss. blood group incompatibility of parents could cause abortion. the examination of couples or twins, blood groups showed that the blood group incompatibility can affect adversely the outcome of pregnancy. couples with blood group incompatibility are more involved in spontaneous miscarriage. antigenes in two different...

  Objective(s): The purpose of this study was preparation and evaluation of PLGA nanospheres containing the influenza virus and different adjuvants, Quillaja saponin (QS) and CpG-ODN.   Materials and Methods: Nanospheres were prepared using the double emulsion-solvent evaporation method. The morphological and physicochemical properties were studied by scanning electron microscopy...

The virus-like particle (VLP) capture assay is an immunoprecipitation method, commonly known as a 'pull-down assay' used to purify and isolate antigen-displaying VLPs. Surface antigen-specific antibodies are coupled to, thus immobilized on solid insoluble matrix such beads. Due their high affinity the target antigen, these can VLPs decorated with cognate antigen anchored in membrane envelope of...

the emergence of plasmodium vivax in dashte moghan in northwestern iran has become a major concern for iranian's health officials. knowledge of genetic make up of the p. vivax populations in this area would give us an insight into the origin of the prevalent infections and the possible routes they are introduced. this paper reports the analysis of a variable region between the two interspecies ...

recurrent aphthous stomatitis (ras) is known as the most common chronic disease of the oral cavity, which affects a range of 5-25% of the population. ras appears to be associated with some human leukocyte antigen (hla) class ii alleles and haplotypes. this study attempts to survey the distribution of hla-drb and -dqb alleles among iranian ras patients and healthy controls. in order to evaluate ...

background: we aimed to value the usefulness of free to total prostate-specific antigen and prostate-specific antigen (psa) density for prostate cancer in the patients with psa levels of 4.0 ng/ml or less. methods: a total of 343 subjects with psa levels of 4.0 ng/ml or less were biopsied. all patients were divided into four groups according to the psa levels: 0 to 1.0 ng/ml, 1.1 to 2.0 ng/ml, ...

objective(s) the aim of this study was to evaluate the expressions of two angiogenic immune-markers (cd-31 and vegf), and one proliferative immune-marker (ki-67) in oral pyogenic granulomas (pg), hemangiomas (hem) and inflammatory gingivitis (ig). materials and methods sixty cases of pg, hem and ig (twenty cases each) were examined. immunohistochemical (ihc) staining was performed based on rout...

background: dense granule antigens (gra antigens) of toxoplasma gondii induce strong antibody response in humans and are considered as useful diagnostic antigens. previous studies reported expression of amino terminal gra8 protein in fusion with large tags such as glutathione-s-transferase. the present study aimed to produce soluble full length immunogenic gra8 in bacteria. methods: gra8 comple...

introduction: although extensive research has been conducted on lung cancer markers, a singular clinically applicable marker has not been found yet. the objective of this study was to evaluate the sensitivity and the specificity of carcinoembryonic antigen (cea) mrna and lung-specific x protein (lunx) mrna biomarkers in peripheral blood to detect lung cancer individually and simultaneously. met...
