1. Allergic sensitization pattern of patients in Brazil
Abstract Objective Allergic sensitization is one of the key components for the development of allergies. Polysensitization seems to be related to the persistence and severity of allergic diseases. Furthermore, allergic sensitization has a predictive role in the development of allergies. The aim of this study was to characterize the pattern of sensitization

2. Homology modeling and epitope prediction of Der f 33
Dermatophagoides farinae (Der f), one of the main species of house dust mites, produces more than 30 allergens. A recently identified allergen belonging to the alpha-tubulin protein family, Der f 33, has not been characterized in detail. In this study, we used bioinformatics tools to construct the secondary and tertiary structures and predict the B and T cel

3. 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

4. Atividade acaricida contra ácaros Dermatophagoides pteronyssinus e D. farinae (Pyroglyphidae) de produto contendo óleos essenciais de Lavadula officinalis e Mentha piperita (Labiatae) / Acaricide activity against mite Dermatophagoides pteronyssinus and D. farinae (Pyroglyphidae) of na herbal product containg essential oils from Lavadula officinalis and Mentha piperita (Labiatae)
House dust mites (HDM) are the greatest source of indoor allergens in Brazil, being closely implicated in respiratory allergic diseases such as asthma and rhinitis. In dwellings, HDM allergens are mainly found on mattresses, sofas and rug surfaces, where several methods such as mattress-covers and acaricides, can be used to control indoor mite infestation. T

5. Associação negativa entre atopia e toxoplasmose em seres humanos
Segundo a hipótese da higiene, a menor exposição a infecções está associada com o aumento na prevalência de doenças alérgicas. O objetivo deste estudo foi investigar a associação entre atopia e infecção por Toxoplasma gondii (Tg) em seres humanos pela análise da resposta imune humoral e celular em pacientes atópicos e não-atópicos, soroposit

6. Anticorpos IgA, IgE e IgG4 específicos a Dermatophagoides pteronyssinus e aos seus alérgenos principais, Der p 1 e Der p 2, em amostras de soro e saliva de crianças e adolescentes alérgicos e não-alérgicos
Allergic rhinitis (AR) is a global public health problem and it is gaining importance due to the rapid increase in its prevalence worldwide. House dust mites as Dermatophagoides spp. are the major sources of allergen sensitization in genetically predisposed subjects. This study aimed to evaluate serum and salivary IgA, IgE and IgG4 levels to Dermatophagoides

7. Humoral and cellular immune responses to Blomia tropicalis and concanavalin A-binding fractions in atopic patients
Blomia tropicalis, Dermatophagoides pteronyssinus and D. farinae are prevalent house dust mites. Concanavalin A-binding components derived from B. tropicalis (Bt-ConA extract) are highly immunogenic in allergic diseases. The aim of the present study was to evaluate the humoral and cellular immune responses to B. tropicalis in mite-sensitized patients. A tota

8. Cloning, sequence analysis, and expression of cDNA coding for the major house dust mite allergen, Der f 1, in Escherichia coli
Our objective was to clone, express and characterize adult Dermatophagoides farinae group 1 (Der f 1) allergens to further produce recombinant allergens for future clinical applications in order to eliminate side reactions from crude extracts of mites. Based on GenBank data, we designed primers and amplified the cDNA fragment coding for Der f 1 by nested-PCR

9. Acaros em amostras de poeira de vestimentas de individuos atopicos e não-atopicos / Mites in dust samples on clothes of atopic and non-atopic individuais
Mites have been considered the most important source of allergen for humans, being found mainly on mattress, pillows, sofas, and rugs dust samples. The objective of this study was to evaluate if human clothes can also be considered another source of mites. 56 dust samples on clothes of volunteers from Campinas were vacuumed and analyzed using an optic micros

10. Prevalence of mites in dust samples from mattress surfaces from single beds or cribs and evaluation of the home environment and sensitivity to mites in atopic patients residing in the south Brazilian city of Londrina / Avaliação do ambiente domiciliar e da sensibilidade cutanea imediata de pacientes atopicos e a prevalencia de acaros em amostras de poeira coletadas de colchões de camas e berços na cidade de Londrina-PR
The prevention and treatment of symptoms related to asthma and allergic rhinitis must include the environmental control of aeroallergens such as mites and cockroaches. The aim of this study was to investigate mites in mattress dust samples from cribs or beds in the southern Brazilian city of Londrina, State of Paraná as well as to evaluate the possible inte

11. Resposta imune humoral e celular a Blomia tropicalis e sua fração ligante de Concanavalina A em pacientes atópicos
Blomia tropicalis (Bt), Dermatophagoides pteronyssinus (Dp) and D. farinae (Df) are the prevalent house dust mites (HDMs). Concanavalin A-binding components derived from B. tropicalis (Bt-ConA extract) have shown to be highly immunogenic in allergic diseases. This study aimed to evaluate the humoral and cellular immune responses to B. tropicalis in sensitize
