Quinoa (Chenopodium quinoa Willd.), which is considered a pseudocereal or pseudograin, has been recognized as a complete food due to its protein quality. It has remarkable nutritional properties; not only from its protein content (15%) but also from its great amino acid balance. It is an important source of minerals and vitamins, and has also been found to contain compounds like polyphenols, ph...

Quinoa seed (Chenopodium quinoa Willd.) has obtained great interest in recent years due to its high nutritional value and its content of natural antioxidants and other phytochemicals with positive biological activity in humans. Their ability as health promoters depends strictly on the processing conditions to which the seeds are submitted. In this work, quinoa seeds were subjected to germinatio...

BACKGROUND The cultivation of saffron is expanding through the southeast of Iran, and allergy to saffron pollen occurs in workers involved in processing this plant. We aimed to clone, sequence and express a major allergen involved in saffron pollen allergy, and to compare the recombinant with the natural allergen. METHODS The N-terminal amino acid sequence of Cro s 1, an allergen from saffron...

As sustainable production of quinoa (Chenopodium quinoa Willd.) increases and its geographic range of cultivation expands, quinoa breeding will allow use of the crop’s wide genetic diversity for cultivar improvement and for adaptation to new agroecosystems and climactic regimes. Such breeding work will require a reliable technique for crossing quinoa plants using hand emasculation. The techniqu...

Chenopodium album is a weedy annual plant in the genus Chenopodium. C. album pollen represents a predominant allergen source in Iran. The main C. album pollen allergens have been described as Che a 1, Che a 2, and Che a 3. The aim of this work was to clone the Che a 1 in Escherichia coli to establish a system for overproduction of the recombinant Che a 1 (rChe a 1). In order to clone this aller...

BACKGROUND Andean indigenous crops such as quinoa (Chenopodium quinoa), kiwicha (Amaranthus caudatus) and kañiwa (Chenopodium pallidicaule) seeds are good sources of minerals (calcium and iron). Little is known, however, about mineral bioavailability in these grains. Thus the aim of the present study was to determine the iron, calcium and zinc potential availability in raw, roasted and boiled q...

Kattusirakam or Vanajira is an important fruit drug in Siddha and Ayurveda systems of Medicine. The market sample of Madras has been identified in our laboratory as the fruits, commonly known as seeds of Centratherum anthelminticum (Willd) Kuntz. (Syn. Veronia anthelmintica Willd) of the family Compositate. The morphology, anatomy, fluorescence analysis and chemical characters of the drug are d...

This is an expository paper, focussing on the following scenario. We have two Markov chains, M and M. By some means, we have obtained a bound on the mixing time of M. We wish to compare M with M in order to derive a corresponding bound on the mixing time of M. We investigate the application of the comparison method of Diaconis and Saloff-Coste to this scenario, giving a number of theorems which...
