Convalescent plasma is that already present in the body and includes anti-SARS-CoV-2 antibodies. This antibodies may kill viral particles, thereby preventing virus entrance into cells. neutralizing procedure has an effect on improvement of a patient's clinical state after receiving convalescent treatment. The possibility this therapy as treatment for individuals infected with SARS-CoV-2 been ev...

Epilepsy is one of the most common neurologic disorders. Underlying cause of epilepsy is unknown in 60 % of the patients. Toxoplasma gondii is an intracellular parasite which is capable of forming tissue cysts in brain of chronically infected hosts including humans. Some epidemiological studies suggested an association between toxoplasmosis and acquisition of epilepsy. In this study we determin...

Avian vitellin antibodies (IgY) obtained after immunization with mouse IgG and mouse IgM in the presence or absence of Freund"s complete adjuvant are suited for labelling with FITC or biotin. In FACS analysis the antibodies prove to be excellent tools in detecting mouse monoclonal antibodies of different isotypes. The working dilution (titer of IgY-FITC) is highest when egg preparations of the ...

The purpose of our experiment is to examine the level of anti-Haemophilus influenza polysaccharide antibody titer in the Korean population. Using ELISA, the level of Hib-PS antibodies in 384 infants and children who were all free from Hib invasive diseases, was tested. And the blood of 50 mothers within 24 hours of delivery and cord blood from their respective full-term neonates was also tested...

background: to study toxoplasmosis in neonates using pcr and serological methods. methods: sera and csf of 104 neonates, hospitalized in infants' ward of taleghani hospital, tehran, iran were examined. the sera were examined for anti toxoplasma gondii lgm and lgg specific antibodies with elisa and ifa techniques, respectively. meanwhile, obtained csfs of the cases were evaluated for the genome ...

Abstract Virus-specific neutralizing antibodies are generally accepted as a correlate of protection against infection, though many questions remain about which components the immune response protect SARS-CoV-2 infection. We longitudinally measured Spike receptor binding domain (RBD)-specific serum IgG and nucleocapsid protein (NP)-specific in human cohort immunized with Pfizer BNT162b2 vaccine....

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...

Conjugate vaccines were prepared by binding hydrazine-treated lipopolysaccharide (DeALPS) from Vibrio cholerae O1, serotype Inaba, to cholera toxin (CT) variants CT-1 and CT-2. Volunteers (n = 75) were injected with either 25 microg of DeALPS, alone or as a conjugate, or the licensed cellular vaccine containing 4 x 10(9) organisms each of serotypes Inaba and Ogawa per ml. No serious adverse rea...

Background: We analyzed both early and late (persistent) phases of each cytomegalovirus (CMV) antibody in mothers with primary CMV infection during pregnancy subsequent congenital for a long period from to after delivery using our stored serum samples. Methods: used samples obtained immunoglobulin (Ig) G seroconversion infant infection. antibodies, including IgG titer, IgM avidity, were assesse...
