BACKGROUND In food allergy, eliciting doses (EDs) of foods on a population level can improve risk management and labeling strategies for the food industry and regulatory authorities. Previously, data available for walnut were unsuitable to determine EDs. OBJECTIVE The objective of this study was to determine EDs for walnut allergic adults and to compare with previously established threshold d...

In 2008, a global production rounding 1,724 and 1,053 million metric tones respectively for walnut and hazelnut has been estimated. Bacterial diseases are threatening these nut crops all over the World. Xhanthomonas arboricola pv. juglandis (Xaj) is the agent of walnut bacteriosis, and has been associated also to brown apical necrosis. Several walnut genotypes have shown a range of tolerance to...

Walnut is extensively used in traditional medicine for treatment of various ailments. It is described as an anticancer, anti-inflammatory, blood purifier and antioxidant agent. In this study, we investigated whether or not Walnut could protect neurons against cisplatin-induced neurotoxicity in rats. Dietary walnut (6%) was assessed for its neuroprotective effects through the alteration in perfo...

Regular walnut consumption is associated with better health. We have previously shown that eight weeks of walnut consumption (43 g/day) significantly improves lipids in healthy subjects. In the same study, gut microbiome was evaluated. We included 194 healthy subjects (134 females, 63 ± 7 years, BMI 25.1 ± 4.0 kg/m²) in a randomized, controlled, prospective, cross-over study. Following a nut-fr...

Surface downwelling and upwelling radiative fluxes are important inputs into hydrologic models that evaluate water budgets, and into land surface data assimilation schemes which are driven with radiative fluxes. For large-scale needs, only remote sensing methods can provide such information. The accuracy of the derived fluxes depends on the inference schemes and on the quality of auxiliary inpu...

The mechanical and physical characteristics have great impact on the shell shucking of walnut. Taking the shucking force as the evaluation indicator, the effects of mechanical and physical characteristics, which include the loading orientation, loading rate, moisture content and walnut partical size, on walnut shucking were investigated by means of single factor test. The results show that: 1) ...

Introduction: Lipid oxidation, including LDL oxidation, plays a pivotal role in development of atherosclerosis. Supplementing diet with antioxidants, such as vitamin E and walnut husk hydroalcoholic extract, may prevent LDL oxidation. In the present study, we investigated the in vitro effects of walnut husk hydroalcoholic extract on serum LDL oxidation caused by copper sulfate. Method: Blood sa...

This rooting study was set up to compare Paradox walnut softwood cuttings from trees which had been: a) propagated through tissue culture, and b) from conventionally grown trees (seedlings). A number of studies on rooting of both hardwood and softwood cuttings of walnut trees have been made by various workers. Although it was reported by Lee, et. al. (1) and others that 100%rooting was obtained...

In the present study, a highly sensitive and simple high-performance liquid chromatographic method was developed and validated for simultaneous determination of three unsaturated fatty acids, αlinolenic acid, linoleic acid and oleic acid in walnut oil. Unsaturated fatty acids were quantified through HPLC using a reversephase C8 column and UV detector. Besides, the antioxidant activity of walnut...
