Asia is the world’s most populous region consisting of highly diverse populations with respect to ancestry and cultural background. It may not be obvious at the outset, but this region is probably an important resource for lessons in allergic disorders. With growing affluence and westernization, the global trends in allergic diseases have increased at tandem, albeit at different rates. In the 1...

the present work concerns on the investigation of the role of polyethylene glycols (pegs) as masking agent for amelioration of extraction-separation of la(iii), eu(iii) and er(iii) ions by the acidic extractant bis(2-ethylhexyl)phosphoric acid (dehpa). the studied solvent extraction system is based on the combination of chelating effect of dehpa in the organic phase on the one hand, and the bin...

The ISAAC project (International Study of Asthma and Allergies in Childhood) was developed with the purpose of determining the prevalence of asthma in schoool children, with the definition of two age groups: infancy, when asthma is more frequent, and adolescence, when mortality associated to asthma is greater. However, the study does not address the risk factors associated with this pathology. ...

Diet and asthma, allergic rhinoconjunctivitis and atopic eczema symptom prevalence: an ecological analysis of the International Study of Asthma and Allergies in Childhood (ISAAC) data. P. Ellwood, M.I. Asher, B. Björkstén, M. Burr, N. Pearce, C.F Robertson and the ISAAC Phase One Study Group. #ERS Journals Ltd 2001. ABSTRACT: Several studies have suggested that the increasing prevalence of symp...

Asthma is a common and sometimes fatal chronic disease, and its prevalence has been increasing in all regions of the world, especially among children. The International Study of Asthma and Allergies in Childhood (ISAAC) Phase I has made reliable data available regarding asthma prevalence in Latin America. Current prevalence for wheezing, exerciseinduced wheezing, and severe episodes was 17.0%,1...

International and regional prevalence comparisons are required to test and generate hypotheses regarding the causes of increasing asthma prevalence in various age groups worldwide. The International Study of Asthma and Allergies in Childhood (ISAAC) is the first such study in children and the European Community Respiratory Health Survey (ECRHS) is the first such study in adults. Therefore, a co...

A simple ion imprinted amino-functionalized sorbent was synthesized by coupling activated carbon with iminodiacetic acid, a functional compound for metal chelating, through cyanoric chloride spacer. The resulting sorbent has been characterized using Fourier transform infrared spectroscopy (FT-IR), elemental analysis, thermogravimetric analysis (TGA) and evaluated for the preconcentration and de...

The aetiology of asthma and allergic disease remains poorly understood, despite considerable research. The International Study of Asthma and Allergies in Childhood (ISAAC), was founded to maximize the value of epidemiological research into asthma and allergic disease, by establishing a standardized methodology and facilitating international collaboration. Its specific aims are: 1) to describe t...
