the features of helicobacter pylori adhesins, their interactions with their host counterparts, regulated and selective gene expressions are amongst the many clever strategies this microorganism undertakes to survive the otherwise sterile gastric milieu. the ingenious crafting of these interactions and the respective host reactions govern, in part, an array of consequences ranging from asymptoma...
patients and methods in this cross-sectional study, peripheral mononuclear cells (pbmcs) were isolated from peripheral blood of 29 patients with newly diagnosed pulmonary tb and 19 patients with positive tuberculin skin test. the pbmcs were activated with ppd for 72 hours. activated cells were harvested, rna was extracted and cdna was synthesized. a real-time taqman method was designed and opti...
Abstract BACKGROUND: Diagnosis of Echinococcus granulosus in the definitive host particularly in dog is the significant complication in the endemic area. OBJECTIVES: The aim of this study is serological detection of E. granulosus in the infected dogs. METHODS: Dot-ELISA based on the copro-antigen and recombinant EPC1 antigen (rEPC1) for antibody detection was performed. Blood and fecal samples ...
background: anaphylactic reactions, such as urticaria, edema, respiratory symptoms, and anaphylactic shock often complicate the course of cystic echinococcosis (ce). methods: to investigate the role of the ige immunoreactive antigen 5 (ag 5) in the sero-positive patients with ce, we determined n-terminal of 57 kda subunit of ag5 responsible for ige and c-terminal of this active antigen related ...
تجزیه و تحلیل تراکنش بین سلول های ایمنی بدن و واکسیناسیون جهت درمان سرطان به وسیله یک مدل ریاضی تبیین شده توسط مشتقات مرتبه کسری در این تحقیق یک مدل ریاضی جهت تبیین تراکنش بین سلول های ایمنی و غده سرطانی، که به صورت یک دستگاه دینامیکی است، را مورد تجزیه و تحلیل قرار می دهیم. در این مدل تأثیر سلول های سیستم ایمنی بدن و برهم کنش بین آن ها بر روی دوره های نهفتگی و بازگشت بیماری سرطان مورد توج...
background: cervical cancer is one of the most common types of women’s reproductive cancers. a major risk factor for cervical cancer is exposure to a group of common sexually transmitted viruses called human papillomavirus (hpv). the over expression of hpv 16 i.e., e6 antigen in the tumors of suspected cervical cancer tissues. however e-6 antigen has hyaluronan binding protein site. methods: t...
background: meningioma is among the most common slow growing central nervous neoplasms, which recurs locally despite the benign histologic features. the aim of this study was to evaluate osteopontin and ki67 expressions in different histologic grades of meningioma in a group of iranian people. methods: in this cross-sectional study, first, the paraffin blocks with the definite pathological diag...
the aim of this study was to prepare a new formula of leishmania major (l. major) crude antigen and evaluate its effect on immune system. for this purpose l. major promastigotes were cultured, harvested, washed, and resuspended in physiologic saline and the suspensions were dispersed in five equal batches. 0.1 ml of various doses of the cocktail antigen were injected intradermaly in three group...
background: the aim of this study was to assess the performance of antigen b (agb) isolated from different echinococcus granulosus intermediate hosts and from different cyst locations for immunodiagnosis of human cystic echinococcosis (ce). methods: hydatid cyst fluids were collected from lung and liver cysts of sheep, liver cysts of goats, lung cysts of camels and cattle, and liver cysts of h...
Hydatid cyst fluid has been used as a source of antigen for the serodiagnosis of Echinococcus granulosus infection. Due to cross-reactions with antigens shared by other helminthes, the specific antigen from hydatid cyst fluid was purified by many workers. We used a relatively simple technique for purification of specific antigen from sheep hydatid cyst fluid. Isopycnic ultracentrifugation w...
