Background Mast cells are activated during allergic reactions, releasing inflammatory mediators that include tryptase. This process leads to the symptoms of an allergic reaction. A transient increase in the total level of serum tryptase indicates mast cell activation, e.g. an anaphylactic reaction. This may help to confirm and assess the extent of a systemic reaction. In the current study, the ...

self pollinated cultivars of hazelnut are limited mainly due to dichogamy and self- incompability. to enhance productivity of hazelnut orchards, identification and selection of suitable polinizers are necessary. to meet this quest, collection and evaluation of iranian hazelnut germplasm have began by department of horticulture research, seed and plant improvement institute, iran, since 1994. ha...

This research was carried out to figure the effect of chemical treatments hazelnut shell powders (HSPs) on elastic properties, ultrasonic wave velocities, and damping properties bio-based epoxy resin (BER) biocomposites. Natural shells (HSs) were chemically treated using sodium hydroxide (NaOH), acetic anhydride (AA). Then, HSs that with NaOH AA, not subjected treatment ground obtain HSPs. The ...

Thermal decomposition of organic matter under inert atmospheric conditions, leading to the release of volatiles and formation of cha is called as pyrolysis. It is also a first step in the biomass gasification. To design of a suitable pyrolysis reactor, understanding of kinetic parameters is essential. In the proposed kinetic model of this study, biomass decomposition is represented as a decompo...

Performance of commercially available component resolved microarray has not been widely evaluated in food allergy. Nut allergy is a prevalent and increasing food allergy in which component resolved diagnosis is crucial. In the context of a multicentric study on pollen and vegetable food allergy in Spain, we enrolled patients (n=100) who had suffered at least two episodes of immediate symptoms a...

the presence of unsaturated fatty acids and phytosterols in hazelnuts and hazelnut products, including hazelnut milk, are useful for health, especially for preventing cardiovascular disease. fermentation with probiotic microorganisms present in kefir grain increases the functional properties of the products. hazelnut milk is nutritious and can be used in drinks in addition to whey. the present ...

Background The high frequency of pollen sensitization has been reported among peanut and tree nuts sensitized patients in our previous study. The antigen homology of peanut and tree nuts antigens with betula was previously shown. However there is a lack of knowledge about the cross-reactivity between hazelnut and grass pollen antigens. The aim of this study is to find out if there is a differen...

background:confirmation of olive oil authenticity and particularly virgin olive oil has a great importance. several advanced chemical and genetic analyses have been used to monitor especial components; however each has its limitations especially when detecting hazelnut-adulterated olive oil. objectives:the objective of this research is to assess the presence of trace amount of hazelnut oil in o...
