Comprehensive two-dimensional gas chromatography (GCxGC) is an emerging technology for chemical separation. Chemical identification is one of the critical tasks in GCxGC analysis. Peak template matching is a technique for automatic chemical identification. Peak template matching can be formulated as a point pattern matching problem. This paper proposes a progressive RAST algorithm to solve the ...

Animals, plants, and algae rely on symbiotic microorganisms for their development functioning. Genome sequencing genomic analyses of these provide opportunities to construct metabolic networks analyze the metabolism communities they constitute. Genome-scale network reconstructions rest information gained from genome annotation. As there are multiple annotation pipelines available, question aris...

در سیستمهای جذب سطحی چند جزئی غیرایده آل، مدلهای تئوری لانگمیر توسعه یافته، لانگمیر دو سایتی توسعه یافته، سیپس توسعه یافته، تئوری محلول جذب ایده آل (iast)، تئوری محلول فضای خالی فلوری-هاگینز (fh-vst) از پیش بینی دقیق جذب تعادلی عاجزند. در اینگونه سیستمهای جذب، تئوری محلول جذب واقعی (rast) می تواند با درنظر گرفتن ضرایب فعالیت ترمودینامیکی، پیش بینی دقیق تری ارائه کند به شرطی که ضرایب فعالیت توسط...

Allergen measurements are used extensively in the formulation of allergy diagnostics and vaccines, yet no purified international allergen standards are available for calibration purposes. The aims of the European Union CREATE project were to develop international standards with verifiable allergen content. Purified natural and recombinant allergens were analyzed by means of SDS-PAGE, mass spect...

Allergic rhinitis is common among children and quite often represents a stage of the atopic march. Although sensitization to food and airborne allergens may appear in infancy and early childhood, symptoms of the disease are usually present after age 3. The aim of this study was to determine the most frequent food and indoor and outdoor respiratory allergens involved in allergic rhinitis in chil...

BACKGROUND: To describe immune and endocrine responses in severe hymenoptera hypersensitivity requiring venom immunotherapy (VIT) during in vitro fertilization (IVF). CASE PRESENTATION: A 39-year old patient was referred for history of multiple miscarriage and a history of insect sting allergy. Four years earlier, she began subcutaneous injection of 100 mcg mixed vespid hymenoptera venom/venom ...
