Amygdalin, also named as ‘laetrile’ and ‘vitamin B17’ was recognized over the years by the followers of natural medicine and has been proposed in research to be having anticancer effects.1 It is one of the most controversial vitamins in the last three decades. It is a cyanogenic plant glucoside belonging to the Rosaceae family found in the pits of numerous fruits, raw nuts as apricot stones, almonds, cherries, peaches and plums.

A problem with synthetic aperture radar (SAR) is that, due to the poor penetrating action of electro- magnetic waves inside solid bodies, the capability to observe inside distributed targets is precluded. Under these conditions, imaging action is provided only on the surface of distributed targets. The present work describes an imaging method based on the analysis of micro-movements on the Khnum- Khufu Pyramid, which are usually generated by background seismic waves.

On the basis of morphology Chenopodium quinoa of the Andes and C. nuttalliae of Mexico appear to be very closely related species. Artificial hybrids have been secured between the two. It is suggested that both species may have been derived from the same original wild type. A weedy quinoa, C. quinoa var. melanospermum, is known from South America, but as yet a weed race closely related to C. nutalliae has not been reported from Mexico.

The consumption of vegetables in Mexico includes a wide variety of plants that grow naturally as weeds in the fields. The intake of these vegetables is very important in the Mexican diet because these plants supply an important input of nutrients and compounds such as fiber, vitamins, minerals, and antioxidants. Thus, the plants may be universally promoted as healthy. However, there is little information about these vegetables of popular consumption, especially in terms of the nutritional changes caused by boiling.
