conclusions in conclusion, occult hbv was found in 36% of patients with negative results for hbsag, but positive results for hcv. detection of hbv-dna in both pbmcs and plasma together in comparison with plasma alone provided more true identification of obi.the svr rate was significantly higher in coinfected patients than mono-infected ones. background occult hepatitis b virus (hbv) infection (...

objective: to determine the diagnostic value of blood cells surface markers in patients with acute appendicitis. methods: in this cross-sectional study, 71 patients who underwent appendectomy following a diagnosis of appendicitis were recruited during a one-year period. the patients were divided into two groups: patients with histopathologically confirmed acute appendicitis and subjects with no...

background: chronic graft versus host disease (cgvhd) is one of the most serious potential complications of allogeneic bone marrow transplantation. study design and method: we analyzed the incidence of cgvhd and its associated risk factors in a group of 161 iranian recipients of hla-identical sibling transplants, with at least 90 days post-transplantation survival. in the majority of cases (n=7...

background: multiple factors have been suggested for prediction of pregnancy in intracytoplasmic sperm injection (icsi) cycles such as the number of injected oocytes, fertilization rate, embryo morphology and quality of transferred embryos. predictive value of these factors is important in icsi outcome. objectives: to evaluate the role of embryo morphology for prediction of pregnancy in icsi cy...

We investigated cup-like nuclear morphology of acute myeloid leukemia blasts in 266 randomly selected patients and its association with hematologic findings, disease markers and outcome data. Cup-like acute myeloid leukemia was diagnosed in 55 patients (21%). It was associated with female sex, high white blood cell and blast cell counts, normal karyotype, and low CD34 and HLA-DR expression. Mut...

Afadin is an intracellular binding partner of nectins, cell-cell adhesion molecules, and plays important roles in the formation of cell-cell junctions. Afadin-knockout mice show early embryonic lethality, therefore little is known about the function of afadin during organ development. In this study, we generated mice lacking afadin expression in endothelial cells, and found that the majority of...

background and aim:  several reports have been published on the successful application of various bone substitute materials (bsm). appropriate physiologic and histologic characteristics and reactions of these materials against host cells are critically important. in this study, the biocompatibility of a new bone substitute material has been evaluated. materials and methods: in this experimental...

this experiment was conducted to determine the effects of the oral consumption of guggulplant resin on the performance and humoral immunity response of broiler chicks. for doing this experiment, 320 one-day old chicks of the cobb 500 strains, in a completely randomized design with 4 treatments and 4 replicates were used. experimental diets include: control diet (without the guggul), control die...

this study was conducted to investigate the effects of curcuma zedoaria and zingiber zerumbet on non-specific immune responses of grouper (epinephelus coioides). fish were fed an experimental diet containing 0, 0.5, 1.0, 2.5 g/kg of c. zedoaria and z. zerumbet mixed diets twice daily for two weeks. non-specific immune parameters such as respiratory burst activity, reactive oxygen species, phago...
