13. Incidence of allergic contact sensitization in central Chinese subjects with chronic urticaria
Abstract BACKGROUND: Chronic urticaria (CU) can be provoked by a wide variety of causes. Some studies suggest contact sensitization may play a role in the disease. OBJECTIVE: To investigate the incidence and distribution characteristics of allergic contact sensitization in central Chinese subjects with CU, and assess contact allergen avoidance measures in

15. Mad, bad and dangerous to know: the biochemistry, ecology and evolution of slow loris venom
Only seven types of mammals are known to be venomous, including slow lorises (Nycticebus spp.). Despite the evolutionary significance of this unique adaptation amongst Nycticebus, the structure and function of slow loris venom is only just beginning to be understood. Here we review what is known about the chemical structure of slow loris venom. Research on a

16. Allergen-Specific Immunotherapy in Patients 55 Years and Older: Results and Review of Literature
Introduction Over the years the immune system suffers many morphologic and functional alterations, which result in a peak of function in puberty and a gradual decrease in the elderly. Aim Treat patients 55 years or older with allergic rhinitis with immunotherapy and then analyze the response to allergens. Materials and Methods From June 2009 to

17. Avaliação clínica e perfil de sensibilização alergênica de crianças asmáticas acompanhadas em um programa de asma
A asma apresenta elevada morbi-mortalidade e é a principal doença respiratória crônica da criança e adolescente. No Brasil tem prevalência de 16,1 a 27,2% e corresponde à terceira causa de hospitalização pelo Sistema Único de Saúde (SUS). É uma doença complexa e de difícil diagnóstico especialmente em crianças, nas quais se observam padrões

18. Simultaneous allergen inactivation and detoxification of castor bean cake by treatment with calcium compounds
Ricinus communis L. is of great economic importance due to the oil extracted from its seeds. Castor oil has been used for pharmaceutical and industrial applications, as a lubricant or coating agent, as a component of plastic products, as a fungicide or in the synthesis of biodiesel fuels. After oil extraction, a castor cake with a large amount of protein is

19. 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

20. Stable silencing of β-lactoglobulin (BLG) gene by lentivirus-mediated RNAi in goat fetal fibroblasts
β-lactoglobulin (BLG), a dominant allergen in goat milk, is difficult to remove by traditional biochemical methods. Its elimination from goat milk by genetic modification therefore poses a major challenge for modern goat breeders. A shRNA targeting BLG mRNA with high interference efficiency was identified, with which lentiviral vectors were used for mediati

21. Characterization of the allergen Sol gem 2 from the fire ant venom, Solenopsis geminata
Sol i 2 is a potent allergen in Solenopsis invicta venom, and most humans exhibit reactivity to it. The Sol gem 2 allergen found in the venom of the Thai tropical fire ant Solenopsis geminata was analysed in the present study. The protein was present in higher amounts than other proteins, as determined by SDS-PAGE, and presumably has allergenic properties si

22. Factores ambientales, nutricionales y de estilo de vida asociados con asma y atopia em uma zona rural de Ecuador. / Factors environmental, nutritional lifestyle y Asociados y con atopic asthma in a rural area of Ecuador.
The aim of this study was to investigate the effect of environmental, anthropometric and lifestyle factors on asthma and atopy in a rural area of Ecuador. We carried out a crosssectional study in order to identify children and adolescents with and without wheeze in the past year to be included in a case-control study. Initially, an exploratory study was cond

23. 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

24. Induction of cell migration and activation in mice by the freshwater sponge Drulia uruguayensis Bonetto & Ezcurra de Drago, 1968 (Porifera: Metaniidae)
Freshwater sponges are abundant in the Amazon region and they have been known to cause dermatitis (acute inflammation) since the beginning of the 20th century. To determine whether additional constituents, besides their body spicules, cause dermatological reactions in humans, an experimental study was developed and carried out using mice and Drulia uruguayen
