OBJECTIVE To evaluate the effect of the intake of whole walnuts and walnut fractions on the oxidant status in mice. METHODS Thirty-six C57BL/6J male mice were randomized to be fed one of three diets: 1) a standard diet (control group), 2) a standard diet with 10% of whole walnuts (walnut-diet group), or 3) a standard diet with 2% of walnut skins (walnut-skin-diet group) for 8 wk. The plasma a...

Walnut kernels are appreciated not only for their mineral content, vitamins, proteins, and valuable lipids, but also the presence of polyphenolic compounds biogenic amines. The temperature storage time effects on some biochemical from collected eight walnut genotypes grown at Fruit Growing Research Extension Station (SCDP) Valcea, Romania, were studied. In general, phenolic carotenoid followed ...

C first walnut trees and orchards were planted during the Spanish mission period (around 1800), using seedlings of early varieties of Persian or English walnut (Juglans regia) chosen for their superior growth and nut quality. Since the 1890s, walnut trees in California have been propagated by grafting or budding desired cultivars onto rootstocks chosen for their adaptation to different physical...

SCOPE English walnut (Juglans regia) belongs to the most important allergenic tree nuts. Co-sensitization with birch (Betula verrucosa) pollen has been reported. We aimed to identify a walnut allergen homologous to the major birch pollen allergen Bet v 1. METHODS AND RESULTS A cDNA encoding a Bet v 1-homologous allergen (Jug r 5) in walnut kernels was cloned by RT-PCR. Jug r 5 was expressed i...

A study to mea~ure the effect of walnut scale infestation on English walnut qualityand yield has shown no differences in yield and no consistentdifferencein kernel quality between infested and non-infested trees for the four years ~f the study. Yield and quality of English walnut are not overly sensitive to walnut scale infestation and some degree of infestation can be tolerated with no measura...

Analysis of genetic structure and differentiation using 12 microsatellite loci of six walnut populations, three each from the Greater Caucasus and the Talysh, revealed a moderate range of variation. The observed number of alleles ranged from 2 to 11 alleles with a mean of 5.6 alleles per locus. The populations differed significantly for the frequency and composition of alleles for ten out of tw...

In order to investigate the shucking technology and design the efficient Sheller, it’s highly significant to study on the mechanical characteristics of walnut. The Pro/E software and finite element method was adopted to build the geometry and finite element model of walnut. Afterwards, the walnut stress distribution with different loads was analyzed to seek the optimum force-applying forms whic...

The distribution and survival of trees during the last glacial maximum (LGM) has been of interest to paleoecologists, biogeographers, and geneticists. Ecological niche models that associate species occurrence and abundance with climatic variables are widely used to gain ecological and evolutionary insights and to predict species distributions over space and time. The present study deals with th...
