Literature about the value of diagnostic tests for hazelnut allergy in children is scarce. For peanut allergy cutoff levels of specific IgE with a 95% positive predictive value (PPV) were published. To evaluate current diagnostics for hazelnut allergy in children, data of 151 children, who underwent a double-blind placebo-controlled food challenge (DBPCFC) for hazelnut were analyzed. The PPV or...

Whenever an electrical machine is meant to be fed by a power converter, the design should be approached as a system optimization, more than a simple machine sizing. A great variety of electrical machines is available to accomplish this goal, and the task of comparing the different options can be very difficult. A general purpose sizing equation, easily adjustable for every topology, that could ...

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...

Aim. Previous studies have shown a higher sensitization rate to hazelnut in processing workers but no relation was found between the respiratory symptoms in workplace and hazelnut sensitization. Material and Method. To evaluate the association between the hazelnut sensitization and workplace-related respiratory complaints, hazelnut processing workers had undergone a questionnaire included work-...

Iran has suitable conditions for cultivating high-quality varieties of hazelnuts (Corylus avellana L.). Most of hazelnut orchards in Iran have been established by planting native genotypes. Aspergillus flavus Link. (AF) is a filamentous fungus affecting hazelnut kernels in orchards and during storage conditions. The most widely explored strategy for reducing aflatoxin contamin...

BACKGROUND Hazelnut allergy can be a consequence of sensitization to cross-reactive pollen, especially from the Fagales family. However, severe allergic reactions after ingestion of hazelnuts without associated pollen allergy have been reported. In these cases, oral sensitization by hazelnut ingestion is plausible. OBJECTIVE We have reported that antiulcer drugs promote oral sensitization to ...

Background Hazelnut-allergic children express variable clinical phenotypes. Tests for the diagnosis of hazelnut allergy are usually conducted on children presenting clinical symptoms following hazelnut ingestion, but also as screening tests after the discovery of a food allergy, mainly to tree nut or peanut. It is important to determine if molecular allergens could be markers of severity in haz...
