The objective of this study was to examine and demonstrate how harvesting age (flower age) contribute to the variations in the quality of Echinacea purpurea (L.) Moench. The effects of different flower developmental stages on caffeic acid derivatives and isobutylamide content are described. These phytochemicals were extracted from fresh plants with 60% ethanol and quantified by the HPLC analysi...

Gattaca is a 1997 science fiction film produced in the US that depicts a future society that uses reproductive technology [5] and genetic engineering in order to produce genetically enhanced human beings. By selectively choosing certain genes [6], scientists and physicians ensure that individuals born using reproductive technologies have desirable physical and psychological traits and prevent u...

Effect of dietary treatment levels on body linear measurements of growing Yankasa rams (Ovis aries) fed sorghum (Sorghum bicolor)Moench stover supplemented with graded levels of dried poultry dropping based diets was assessed using thirty growing Yankasa rams (Ovis aries) consisting of five treatments (T1-T5). Each treatment consisted of three replicates with two animals per replicate. T1: were...

Seedlings of both KS8 and N32 sorghum [Sorghum bicolor (L.) Moench] were high in dhurrin [p-hydroxy-(S)-mandelonitrile-BD-glucoside] and thus in hydrocyanic acid potential (HCN-p), but the HCN-p of mature leaves from field-grown plants of KS8 was only about one-tenth as high as that of N32. A study of the inheritance of this large difference between KS8 and N32 revealed that a single major gene...

Fluorescence microscopy was used to determine the l ocation of Bglucans in sorghum. Sections from three genetically different sorghum cultivars were st ained with Calcofluor or Congo Red , fluorochromes which have been reported to react with 13-glucans. Autofluorescence, indicative of ferulic acid in other cereals, was observed in untreated sections. When stained sections were treated with endo...
