Epidemiological studies suggest that the incidence of CVD and postmenopausal osteoporosis is low in the Mediterranean area, where herbs and nuts, among others, play an important role in nutrition. In the present study, we sought a role of walnuts (Juglans regia L.) in endothelial and bone-cell function. As the endothelial cell expression of adhesion molecules has been recognised as an early ste...

It was investigated whether a standard mouse diet (AIN-76A) supplemented with walnuts reduced the establishment and growth of LNCaP human prostate cancer cells in nude (nu/nu) mice. The walnut-enriched diet reduced the number of tumors and the growth of the LNCaP xenografts; 3 of 16 (18.7%) of the walnut-fed mice developed tumors; conversely, 14 of 32 mice (44.0%) of the control diet-fed animal...

There is extensive evidence that walnut consumption is protective against cardiovascular disease and diabetes in the healthy population, but the beneficial effects of walnut consumption in individuals with the metabolic syndrome (MetS) remain uncertain. We compared a range of cardio-metabolic traits and related tissue gene expression associated with 21 weeks of dietary walnut supplementation in...

The walnut aphid, Chromaphis juglandicola is a pest known in California for more than 100 years. The introduction of the parasitic wasp Trioxys pallidus from Iran in 1969 led to a dramatic success in the biological control of walnut aphid populations in California, and has provided sustained control of this devastating pest for the past 39 years. However, in recent years we have seen renewed ou...

The effects of extraction solvents (hexane, ethyl-acetate, acetone, ethanol, methanol, and water) on the content of phytochemicals including total polyphenols, flavonoids and condensed tannins, as well as antioxidant activities of walnut green husk were investigated. The results showed that extraction solvents significantly affected phytochemicals content and antioxidant activities of walnut gr...

due to the complex assessment of young walnut cultivars (juglansregia l.) based on morphological traits, advance molecular tools have provided a new prospect for cultivar identification and dna fingerprinting. in this study, specific molecular keys were identified for 5 iranian walnut cultivars (juglansregia l.) using 30 ssr markers. the results showed that 5 ssr markers produced polymorphic ba...

For at least the past decade, an unusual decline of black walnut (Juglans nigra) has been observed in several western states. Initial symptoms involve a yellowing and thinning of the upper crown, which progresses to include death of progressively larger branches (Figure 1). During the final stages large areas of foliage may rapidly wilt. Trees often are killed within three years after initial s...

AIM Identification of cyclopropyl fatty acids in walnut oil. METHOD GC/MS method was developed for the determination of eight cyclopropyl fatty acids in walnut (Juglans regia) oil. RESULTS Monocyclopropane acids: methyl 9-cyclopropyl-nonanoate, 6,7-methylene-, 8,9-methylene-, 9,10-methylene-, 11,12-methylene octadecanoates, and dicyclic acid - methyl 9,10,12,13-dimethylene octadecanoate, tr...

oxidative stability of walnut (juglansregia l.) was evaluated over a period of 1 year storage in various conditions. the whole walnuts, walnut kernels, walnut chopped kernels, walnut kernels packaged in polyethylene (pet) under vacuum and poly propylene (pp) contain of co2 were kept in a normal condition (temperature, 19-30˚с and relative humidity (rh), 35-45%). the whole walnuts and walnut ker...
