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. 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

3. Identificação de isoformas antigênicas de Dermatophagoides pteronyssinus reconhecidas por anticorpos IgE e IgG1 em pacientes atópicos e não atópicos
The house dust mite Dermatophagoides pteronyssinus (Dp) is a major source of indoor allergens in the world and considered important for sensitization of genetically predisposed subjects. Some allergens from this mite can occur as isoallergens with differences in amino acid sequences or glycosylation, leading to differences in allergenic sensitization. The ai

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. Efeito imunomodulatório in vivo e in vitro do oligodeoxinucleotídeo CpG na imunização com ovalbumina em camundongos nas fases neonatal e adulta. / In vivo and in vitro immunomodulatory effect of CpG-containing oligodeoxynucleotide in ovalbumin immunization of newborn and adult mice.
The allergy development may occur in the early life, during the pregnancy or postnatally at the first months of life. In mice, it is described a predisposition to Th2 biased response in the neonatal period, favoring the development of allergic response. The maturation of functions related to Th1 response by the use of immune adjuvants may be beneficial to th

6. 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

7. 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

8. 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

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. Resposta de anticorpos IgE, IgG1 e IgG4 aos componentes ligantes de Concanavalina A isolados de Blomia tropicalis (Acari: Echimyopodidae) em indivíduos alérgicos e não alérgicos
Blomia tropicalis (Bt) e Dermatophagoides pteronyssinus (Dp) são os principais ácaros da poeira domiciliar em países tropicais e subtropicais que estão associados com doenças alérgicas. Antígenos glicosilados são altamente imunogênicos e estão envolvidos em diferentes patologias, incluindo alergias. Os objetivos deste estudo foram avaliar a respost

12. Levantamento da fauna acarina em amostras de poeira em domicilios da cidade de Campinas/SP
The aim of this study was to evaluate mite numbers and species in house dust samples from different dwellings sites. A total of 58 homes in Campinas/SP was chosen. Samples were collected once from pantries, rugs (Iiving rooms and bedrooms), sofas, curtains (Iiving rooms and bedrooms) and upper and lower surfaces of mattresses, in the last also included the b
