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...

In this work the Origanum vulgare leaf extract was used to green synthesis of Ag nanoparticles (NPs) supported on Hazelnut shell as an environmentally benign support. The Ag NPs/Hazelnut shell as an effective catalyst was prepared through reduction of Ag+ ions using Origanum vulgare leaf extract as the reducing and capping agent and Ag NPs immobilization on Hazelnut shell surface in ...

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...

Ecosystem-based approaches to nutrient management are needed satisfy crop requirements while minimizing environmental impacts of fertilizer use. Applying residues as soil amendments can provide essential inputs from organic sources improving retention, health, water conservation, and performance. Tree hulls, husks, shells have been found contain high concentrations potassium across species incl...

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 ...

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 ...

Drying is one of the most important stages of hazelnut processing and its optimization improves the quality of the final product. The quality of hazelnut is dependent on chemical and organoleptic characteristics of fruit that is affected in the drying process. In present research, samples of Gerd cultivar of hazelnut (Corylus avellana) were dried in shelled and in-shell forms using a laboratory...
