in recent decades, biotechnologists have striven to improve the quantity and quality of food supply. producing genetically modified (gm) foods is one of the main goals and many countries all over the world have approved the distribution and consumption of the labeled gm foods in their own regions. however, there are still few groups having concerns about allergenicity of gm foods. this review h...

OBJECTIVE Allergic disease caused by airborne pollen is a major health problem in China. Intensive study on pollen allergens can be of great help for preventing and treating pollinosis. Four aspects of the study on pollen allergens in China including major allergic pollen in our country, analysis and purification of pollen allergen composition, recombinant pollen allergens and clinical applicat...

Allergic Bronchopulmonary Aspergillosis (ABPA) is a severe respiratory disease caused by the fungus Aspergillus fumigatus (Af). It occurs as secondary complication mostly in patients with atopy and cystic fibrosis. The standardized and well-characterized allergens are essential for the immunodiagnosis of ABPA as well as for understanding the pathophysiology of the disease. Molecular cloning was...

BACKGROUND Respiratory allergy triggered by pollen allergens is increasing at an alarming rate worldwide. Sunflower pollen is thought to be an important source of inhalant allergens. Present study aims to identify the prevalence of sunflower pollinosis among the Indian allergic population and characterizes the pollen allergens using immuno-proteomic tools. METHODOLOGY Clinico-immunological te...

BACKGROUND: A computerized statistical analysis of allergy skin test results correlating patient reactivities initiated our interest in the cross-reactive allergens of mesquite tree pollen. In-vitro testing with mesquite-sensitized rabbits and a variety of deciduous tree pollens revealed so many cross-reactivities that it became apparent there could be more allergens in mesquite than previously...

BACKGROUND Patients sensitized to common pets (cat, dog) frequently display an immunoglobulin (Ig) E-mediated response to allergens from other animals. OBJECTIVE To evaluate whether individuals sensitized to common pets might be at higher risk of developing allergic sensitization to other mammalian allergens. METHODS The study population comprised 900 consecutive patients (300 individuals s...

Pathogenesis related (PR) proteins are one of the major sources of plant derived allergens. These proteins are induced by the plants as a defense response system in stress conditions like microbial and insect infections, wounding, exposure to harsh chemicals, and atmospheric conditions. However, some plant tissues that are more exposed to environmental conditions like UV irradiation and insect ...

patients and methods in this cross sectional study, 295 volunteers with the signs and symptoms of allergic diseases who referred to the khuzestan jahad daneshgahi medical center in ahvaz during 2010 were investigated. all patients were subjected to skin prick test (spt) with common allergenic extracts. data were analyzed by spss-18 software using chi square test. results seventy subjects, compr...

Background In natural history of allergy, in some patients sensitized to aeroallergens, appear allergy to novel allergens, and in some cases this are food allergens. Subcutaneous immunotherapy (SIT) is the method of treatment patient with pollen allergy, and one of the aim of this treatment is protection against development novel allergy, but sometimes in clinical practice we observed hypersens...
