Background: Glycation of proteins is a non-enzymatic spontaneous process that occurs in diabetes mellitus and aging, altering the structure and function of proteins. IgG undergoes glycation leading to changes in its reactivity to antigen and fixation of complement.   Objective: This study aimed at revealing the effect of glycation on the interaction of IgG with anti-IgG using electroimmunoassay...

Asthma is one of the most common causes of office visits in the primary care and emergency care settings. Individuals are often able to maintain symptomatic control with long-term pharmacological therapy. Exacerbations of asthma commonly occur due to exposure to triggers such as viruses, pollutants, and allergens. While it is widely accepted that exposure to immunoglobulin E food allergens can ...

A monophyletic group of black yeast-like fungi containing opportunistic pathogens around Exophiala spinifera is analyzed using sequences of the small-subunit (SSU) and internal transcribed spacer (ITS) domains of ribosomal DNA. The group contains yeast-like and annellidic species (anamorph genus Exophiala) in addition to sympodial taxa (anamorph genera Ramichloridium and Rhinocladiella). The ne...

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 st...

Background: Toxoplasmosis is well known as an important infection in pregnant women. Although many serologic methods are available, diagnosis of early Toxoplasmosis may be extremely difficult. Objective: To detect the Toxoplasma IgG antibodies developed at the early stage of infection in pregnant women. Methods: 225 pregnant women, who were in the 2nd to 4th month of their pregnancy, enrolled i...

Background/Objective: To clarify the state of different immunologic factors in patients with acute rheumatic fever (ARF) and rheumatic heart disease (RHD) compared to healthy individuals.Patients and Methods: Patients with ARF (#21), patients with RHD six months after the onset of ARF (#19), and healthy children from the same age group with normal physical examination and no history of pharyngi...

Forty patients with cataracts, as well as 40 patients with proven ocular toxoplasmosis were enrolled in this prospective clinical study. Serum IgG and aqueous IgG in both groups were measured by enzyme-linked immunosorbent assay (ELISA) and the corresponding ratios were calculated. Serum IgG/aqueous humor IgG ratio was less than 100 in the patient group and more than 100 in the control gro...

Fc gamma receptors (Fc gammaRs) bind the constant Fc region of IgG molecules. IgG/antigen-containing immune complexes elicit a variety of effector functions in cells that express activating Fc gammaRs. Because activating Fc gammaRs are present on cells from the innate immune system, such as dendritic cells, monocytes/macrophages and granulocytes, these IgG receptors form a crucial link between ...
