Cassava (Manihot esculenta, Crantz) roots are the primary source of calories for more than 500 million people, the majority of whom live in the developing countries of Africa. Cassava leaves and roots contain potentially toxic levels of cyanogenic glycosides. Consumption of residual cyanogens (linamarin or acetone cyanohydrin) in incompletely processed cassava roots can cause cyanide poisoning....

The results are presented of a double-blind therapeutic trial of hydroxocobalamin and riboflavine in Nigerian patients suffering from a degenerative neuropathy. Although no benefit from either vitamin was demonstrated, this may reflect the inadequacy of the dosages used. The results are discussed in relation to the hypothesis that dietary cyanide and cyanogens are responsible, at least in part,...

Konzo is an irreversible paralysis of the legs that occurs mainly in children and young women associated with large cyanide intake from bitter cassava coupled with malnutrition. In East Africa outbreaks occur during drought, when cassava plants produce much more cyanogens than normal. A wetting method that removes cyanogens from cassava flour was taught to the women of three konzo villages in M...

Cassava (Manihot esculenta Crantz), a staple crop for millions of sub-Saharan Africans, contains high levels of cyanogenic glycosides which protect it against herbivory. However, cyanogens have also been proposed to play a role in nitrogen transport from leaves to roots. Consistent with this hypothesis, analyses of the distribution and activities of enzymes involved in cyanide metabolism provid...

In this study, some anti-nutritional factors present in oil-free seeds of egusi (Citrullus colocynthis L.) seed cake were determined. Oil was extracted from the oil-free egusi seed by the Soxhlet extraction method. The anti-nutritional factors were determined using the standard methods. The result of anti-nutritional factors analysis revealed that the seed contains phytate (3.09 ± 0.65mg/100g),...

introduction: photonics refers to the technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. photonic technology in the meridian and acupoints research has shown the unique advantages, by which the microcosmic material basis and macroscopic phenomena research can be integrated to interpret the occurrence of propagated sensation along me...

man has always been curious about his natural environmental, and has always been trying to know it more. to do this, he has employed many different ways and has used different information. in the meantime, he has examined nature phenomena indirectly and using remote sensing. today, expert and groups of experts are using remote sensing documents and this has caused them to believe that remote se...
