Abstract This study aims to determine the most frequent titers of anti-A and anti-B (both presumed immunoglobulin [Ig]M IgG) in Iranian group O blood donors compare these titer values with those found other studies. In addition, alloantibody production plasma levels four IgG subclasses were compared between high-titer non–high-titer groups. investigated 358 samples. Based on results, two groups...

A passive hemagglutination (PHA) test for measles was evaluated in comparison with hemagglutination inhibition (HI) and neutralization (NT) tests. The PHA test determines exclusively the level of antibody directed to the hemagglutinin protein of measles virus. The ratio of PHA to HI titer was 1 to 32 (geometric mean, 6.5) for the first 5 weeks of infection but declined to near unity thereafter....

background: hepatitis b is one of the most important etiologic factors of acute and chronic hepatitis, cirrhosis of the liver and hepatocellular carcinoma. the best preventive method is vaccination. the aim of the study was to evaluate the immunization rate against hepatitis b in medical health personnel. materials and methods: this study was conducted on 331 health care workers employed in pub...

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...

background & aim: a feeding trial was conducted to investigate the effect of periodically use of garlic on growth ‎performance, and antibody titer to newcastle and infectious bursal diseases in broiler ‎chickens. experimental: ross broiler chicks randomly allocated into the 10 dietary treatments ‎for 6 weeks. a 3 × 4 factorial experiment was used as three periods of feeding (starter, grower...

Aim: To investigate the clinical characteristics of diabetic patients with a low-titer positive for the anti-glutamic acid decarboxylase 65 antibody (GAD antibody). Methods: The subjects were 420 diabetic inpatients. The endogenous insulin secretion was estimated on the basis of the Cpeptide immunoreactivity from a 24 h urine collection (uCPR). Clinical variables were compared between patients ...

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...

this experiment was conducted to determine the effects of myrtle essential oil (meo) on growth performance, carcass characteristics, antibody titer and blood parameters of broiler chickens. a total of 200 ross 308 broiler chickens were allocated to five dietary treatments with four replicates of 10 birds each. dietary treatments were prepared by formulating a corn-soybean meal-based diet free o...

While a number of studies have identified host factors that influence endosymbiont titer, little is known concerning environmental influences on titer. Here we examined nutrient impact on maternally transmitted Wolbachia endosymbionts in Drosophila. We demonstrate that Drosophila reared on sucrose- and yeast-enriched diets exhibit increased and reduced Wolbachia titers in oogenesis, respectivel...

Hepatitis B remains a global burden, with estimated 15 to 40 percents of infected individuals eventually suffer from liver cirrhosis, liver failure, and hepatocellular carcinoma. Vaccination aims to form anti-HBs antibody with protective titer to prevent infection. CD4 T cell lymphocytes are known to play a major role in establishing immunity after vaccination. This study aimed to investigate p...
