1. Cloning, bioinformatics analysis, and expression of the dust mite allergen Der f 5 of Dermatophagoides farinae
Crude extracts of house dust mites are used clinically for diagnosis and immunotherapy of allergic diseases, including bronchial asthma, perennial rhinitis, and atopic dermatitis. However, crude extracts are complexes with non-allergenic antigens and lack effective concentrations of important allergens, resulting in several side effects. Dermatophagoides far

2. Alérgenos de pólen de Lolium multiflorum (Lam. 1779): determinação da reatividade cruzada de anticorpos IgE aos componentes alergênicos de extratos comerciais de gramíneas
Background: Lolium multiflorum (Lm) grass pollen, Poaceae family, is the major cause of pollinosis in South Brazil. There are no studies evaluating the cross-reactivity between allergenic fractions from L. multiflorum and other pollen grass species. Objective: To evaluate the sensitization to Lm pollen allergens in patients with pollinosis through the detect

3. Avaliação da sensibilidade de cães com dermatite alérgica aos extratos alergênicos padronizados de ácaros da poeira domiciliar / Evaluation of the sensibility from dogs with allergic dermatitis towards standardized allergenic extracts of house dust mites
The objective of this case-control study was to evaluate whether allergenic extracts from five species of house dust mites standardized for humans may be taken into account in the diagnosis of the canine atopic dermatitis. Extracts of Dermatophagoides pteronyssinus, D. farinae, Blomia tropicalis, Lepidoglyphus destructor and Tyrophagus putrescentiae have bee

4. Avaliação da sensibilidade imediata de pacientes atopicos por meio de teste cutaneo de puntura (prick test) a extrato de traça-de-livro (Lepisma saccharina) padronizado em unidades biologicas / Evaluation of immediate sensitive to a biological Unit-Standardized extract of silverfish (Lepisma saccharina) in atopic patients by skin prick test
In Brazil, allergic patients with allergic rhinitis and/or asthma present sensibility for several aeroallergens mainly from house dust mites. Other potential sources of allergens like silverfish remain to be investigated as really allergenic and firmly related to respiratory allergic diseases. The aim of this study was investigate by skin prick test the imme

5. Preparation and characterization of liposomes entrapping allergenic proteins
This work presents results of the preparation and characterization of small unilamellar liposomes for entrapping allergenic proteins extracted from the biomass of Dreschlera (Helminthosporium) monoceras cultivated by solid fermentation. Protein was entrapped by the dehydration-rehydration method, using lyophilization of preformed liposomes in order to preven

6. Skin manifestations caused by Brazilian traumatic, allergenic, and venomous plants: main species, therapeutic and preventive measures
Brazilian flora is very rich and a large number of specimens can cause adverse reactions, from mild erythema to cutaneous necrosis. Plants or vegetal extracts are always suspected of contact dermatitis; they are found in all types of environments, including dwellings. Other harmful effects, which can be identified by clinical manifestations and the aid of th

7. Humoral immune responses induced by Kudoa sp. (Myxosporea: Multivalvulida) antigens in BALB/c mice
The majority of Kudoa species infect the somatic muscle of fish establishing cysts. As there is no effective method to detect infected fish without destroying them these parasited fish reach the consumer. This work was developed to determine whether this parasite contains antigenic compounds capable of provoking an immune response in laboratory animals, in o

8. Produção, recuperação e caracterização de proteinas alergenicas da biomassa de Drechslera (Helminthosporium) monoceras obtida por fermentação em estado solido
The purpose of this work was the production, recovery and characterization of allergenic proteins of Drechslera (Helminthosporium) monoceras biomass; cultivated by solid-state fermentation, for the obtainment of standardized mould allergenic extract, applicable to diagnosis of allergy diseases. Bioreactors based on Raimbault-type aerated fixed bed columns we

9. Encapsulamento em lipossomas de proteinas individuais e em misturas simulando extratos alergenicos
Os lipossomas têm sido utilizados como imunoadjuvantes antigênicos, em estudos que enfatizam a sua atuação no sistema imunológico. Extratos peptídicos ou protéicos de várias fontes foram encapsulados em lipossomas ou associados à sua superficie, e aplicados em imunoterapias e vacinas. Apesar disso, poucos são os estudos voltados para a performance

10. Safety Assessment of Biotechnology Products for Potential Risk of Food Allergy: Implications of New Research
Food allergy is a potential risk associated with use of transgenic proteins in crops. Currently, safety assessment involves consideration of the source of the introduced protein, in silico amino acid sequence homology comparisons to known allergens, physicochemical properties, protein abundance in the crop, and, when appropriate, specific immunoglobulin E bi

11. Fungal allergens.
Airborne fungal spores occur widely and often in far greater concentrations than pollen grains. Immunoglobulin E-specific antigens (allergens) on airborne fungal spores induce type I hypersensitivity (allergic) respiratory reactions in sensitized atopic subjects, causing rhinitis and/or asthma. The prevalence of respiratory allergy to fungi is imprecisely kn

12. Allergenic Characterization of Tropomyosin from the Dusky Brown Cockroach, Periplaneta fuliginosa
Household arthropods are one of the most common causes of allergic diseases. Four species of cockroaches are found to reside in Korean homes, but published work deals almost exclusively with the German and American cockroaches. This study was undertaken to investigate the cross-reactive allergenic components of the dusky brown cockroach, Periplaneta fuligino
