1. 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

2. Prevalence of rhinitis symptoms among textile industry workers exposed to cotton dust
INTRODUCTION: The respiratory tract is one of the main points of entry of foreign substances into the body. Because of its location, the respiratory tract is heavily exposed to harmful agents, such as gases, vapors, or aerosols. AIM: Our objective was to evaluate the symptoms of occupational rhinitis in workers exposed to cotton dust. METHOD: The prospective

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. The hammock: a reservoir of allergens
INTRODUCTION: Asthma affects approximately 10% of the world's population. Sensitization to allergens is an important risk factor, and exposure to allergens is associated with disease severity. METHODS: We performed skin tests to evaluate allergen sensitization to mites, cockroaches, cats, dogs, and molds in 73 asthmatic patients. Enzyme Linked Immunosorbent

5. 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

6. 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

7. 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

8. Asma no adolescente prevalência, gravidade e fatores de risco associados em São José do Rio Preto - SP.
Asthma is a serious public health problem worldwide, due to its frequency, morbidity and increasing prevalence, especially in childhood. Comparative studies on asthma prevalence among distinct regions and periods of time reveal differences which are essential to monitor the secular trend of asthma occurrence and suggest hypotheses about its causes. With simp

9. 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

10. 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

11. Exposição a alérgenos de poeira doméstica e sua associação com atopia e asma em crianças entre 4 e 12 anos de idade em Salvador, Bahia. / Exposure to house dust allergens and their association with atopy and asthma in children between 4 and 12 years-old in Salvador, Bahia.
Introdução: Os alérgenos de poeira domiciliar são considerados fatores de risco para o aumento na prevalência e incidência das doenças alérgicas, observado nos últimos 30 a 40 anos. Alguns estudos mostram uma relação dose-resposta entre exposição a estes alérgenos e ocorrência de sensibilização e desencadeamento de sintomas alérgicos. Objet

12. 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
