Oxidative stress plays an important role as a mediator of damage produced by fructose metabolism. This work was designed to investigate the effect of diet supplemented with quinoa seeds on oxidative stress in plasma, heart, kidney, liver, spleen, lung, testis and pancreas of fructose administered rats. Fructose administration (310 g/kg fodder for 5 weeks) caused oxidative stress that was manife...

This study examined the polyphenol composition and antioxidant properties of methanolic extracts from amaranth, quinoa, buckwheat and wheat, and evaluated how these properties were affected following two types of processing: sprouting and baking. The total phenol content amongst the seed extracts were significantly higher in buckwheat (323.4 mgGAE/100 g) and decreased in the following order: bu...

background and objectives: quinoa (chenopodium quinoa willd.) is a member of amaranthaceae family that originated in the andean region in bolivia, chile and peru five thousands of years and so it has a tiny and round seeds. quinoa in different combinations of food used as food, as well as how to cook like rice grains and known as the inca rice in the south american countries. the high nutrition...

Transcripts were produced in vitro by run-off transcription from full-length cDNA of RNA1 and RNA2 of grapevine fanleaf nepovirus (GFLV; isolate F13) cloned downstream from a bacteriophage RNA polymerase promoter. These transcripts, which possess a 5' terminal cap structure and a non-viral G residue instead of the naturally occurring genome-linked viral protein (VPg), are infectious to Chenopod...

Synthetic vitamin preparations have grown in popularity to combat health risks associated with an imbalanced diet, poor exercise and stress. In terms of bioavailability and diversity, they lack behind vitamins naturally occurring in plants. Solutions to obtain plant-derived vitamins at a larger scale are highly desirable. B vitamins act as precursors of enzymatic cofactors, thereby regulating i...

Here we present a high-resolution chromosomal spectral map derived from synchrotron-based soft X-ray spectromicroscopy applied to quinoa species. The label-free characterization of quinoa metaphase chromosomes shows that it consists of organized substructures of DNA-protein complex. The analysis of spectra of chromosomes using the scanning transmission X-ray microscope (STXM) and its superposit...

Agriculture in the high Andean region of Peru is usually made under adverse conditions, with frequent drought and frost Abiotic factors and in impoverished soils and mostly oriented to auto subsistence production. The diets consumed in the highland usually contain various sources of dietary protein, among them a mixture of cereals (barley, wheat and maize) with native grains (quinoa and amarant...

The putative 38 kDa movement protein (P38) gene, located on the RNA2 of grapevine fanleaf nepovirus (GFLV), was cloned in Escherichia coli and expressed as a fusion protein fused to six histidines (6HisP38). This protein was purified and used to produce a specific polyclonal antiserum from which immunoglobulins were isolated by immunoaffinity against the recombinant 6HisP38. Western immunoblot ...

A new species, Cactodera milleri n. sp., is described and illustrated from specimens obtained from roots of common lambsquarter, Chenopodium album L., from Mattawan, Michigan. Cactodera milleri can be differentiated from other Cactodera species by the presence of punctated egg shells and a second-stage juvenile (J2) stylet length averaging 21.8 mum as measured from freshly killed specimens in w...
