Results IgE to hazelnut extract was significantly higher in children with severe than with no or mild symptoms. Sensitization to rCor a 1.04 was common among both children and adults, while sensitization to rCor a 8 was rare. In 13% of children and 49% of adults with a severe hazelnut allergy, only sensitization to rCor a 1.04 was observed and not to other water-soluble allergens. Sensitization...

Hazelnut (Corylus avellana L.) is affected by dieback (DB) and decline (D) diseases causing significant losses to hazelnut production in the Eshkevarat (Guilan province, northern Iran) as the main region for hazelnut production in Iran. Although, causal agents of these disorders have remained uncertain for many years. During 2017-18, results of a survey on DB and D diseases in hazelnut...

Background and aim Allergens from nuts are known to often induce severe allergic reactions in sensitive individuals. Nuts are a nutrient dense food and a good source of unsaturated fatty acids and other lipids. The allergenic properties of hazelnut allergens could be altered by binding to or being in close proximity to these lipids. The aim of this study was to purify and characterize natural C...

Eastern chipmunk (Tamias striatus) is seed predator that has the ability to affect the diversity and abundance of certain tree species in a forest. This study tested the seed preference of eastern chipmunks on the border of Wisconsin and the Upper Peninsula of Michigan at University of Notre Environmental Research Center. Cafeteria style feeding trials were done in a laboratory to test the pref...

BACKGROUND Allergenicity of foods can be influenced by processing. Tree nuts are an important source of nutrition and increasingly consumed; however, processing methods are quite variable and data are currently lacking on the effects of processing on allergenicity. OBJECTIVE To perform a systematic literature review on the effects of food processing on the allergenicity of tree nuts. METHOD...

BACKGROUND The prevalence of IgE reactivity against genuine walnut and hazelnut allergens is poorly defined. OBJECTIVE The IgE response to walnut and hazelnut was investigated in Italian patients with primary allergy to these nuts. METHODS Sera from 36 patients allergic to hazelnut and/or walnut, not reactive to PR-10, profilin, and LTP, underwent immunoblot analysis with extracts of both n...

BACKGROUND There is very few data available on the prevalence of food hypersensitivity among adults with asthma. The aim of this study was to explore the prevalence of self-reported adverse reactions and IgE sensitization to the different foods and to determine the spectrum and the prevalence of food-related gastrointestinal symptoms in adults with and with no asthma. METHODS A cross sectiona...

Fusarium lateritium is a globally distributed plant pathogen. It was recently reported as the causal agent of nut gray necrosis (NGN) on hazelnut. Isolate characterization within F. lateritium was undertaken to investigate how morphological and molecular diversity was associated with host and geographic origin. Morphological studies combined with inter-simple-sequence repeat (ISSR) analysis, an...

BACKGROUND Patients sensitized to birch pollen frequently suffer from a food allergy to plant foods such as celery, carrots, or hazelnut. One of the main manifestations of birch pollen-related food allergy is the oral allergy syndrome. Skin tests and allergen-specific immunoglobulin (Ig) E determinations are poor predictors of such reactions when assessed by double-blind placebo-controlled food...
