background: toxoplasmosis is a world wide parasitic disease infecting human by oocyst, tissue cyst or tachyzoites in raw meat, water or congenitally during pregnancy. toxoplasmosis can cause abortion in pregnant women. the current seroepidemiological study was designed to assess toxoplasmosis in pregnant women with or without the history of abortion. methods: in a case–control study the antibod...

Fc region binding peptide conjugated with attenuated cationic amphiphilic lytic L17E trimer [FcB(L17E)3] was designed for immunoglobulin G (IgG) delivery into cells. Particle-like liquid droplets were generated by mixing Alexa Fluor 488 labeled IgG (Alexa488-IgG) FcB(L17E)3. Droplet contact the cellular membrane led to spontaneous influx and distribution of Alexa488-IgG throughout cells in seru...

antiphospholipid antibodies (apla) may be detected in normal pregnancies and also may cause thrombosis, recurrent fetal loss, placental infarction and preeclampsia. in the present study the possible differences in apla titer between healthy pregnant women and preeclampsia cases without history of thrombosis was examined. the apla titer in 50 healthy pregnant women with 50 preeclampsia cases wit...

objectives: ctxb (cholera toxin b subunit) contributes to a vaccine's efficacy by stimulating production of the anti-ctxb antibody. various attempts have been made to increase production of this antibody. chitosan is a mucoadhesive polysaccharide that has tremendous potential for oral vaccine delivery in terms of its exclusive features that include biocompatibility, biodegradability, high charg...

The FcγRIIA/CD32A is mainly expressed on platelets, myeloid and several endothelial cells. Its affinity considered insufficient for allowing significant binding of monomeric IgG, while its H131R polymorphism (histidine > arginine at position 131) influences multimeric IgG2. Platelet FcγRIIA has been reported to contribute IgG-containing immune-complexe clearance. Given our finding that plate...

Background: Pemphigus is an autoimmune bullous disease and it is unclear what triggers and deteriorates it. The current study aimed to evaluate whether increasing the IgG antibody titer represents a good indicator of the pemphigus recurrence. Objectives: The current study aimed to evaluate whether increasing IgG titer is an indicator of the expected recurrence. Patients and Methods: The current...

abstract background and aims: the burden of hiv infection and disease continues to be a major global public health concern all over the world. this study was conducted to measure igg antibody against ebv viral capsid antigen (ebv-vca igg), herpes simplex type1, and 2 to determine the seroprevalence of this infection in hiv-positive population. materials and methods: a cross-sectional study betw...
