The effort of this work was to prove whether there exists any relation between stress factors caused by content of cadmium and zinc, and content and composition of opium alkaloids codeine, morphine, narcotine (noscapine) and papaverine contained in poppy seeds and capsules (Papaver somniferum L.) in 14 samples of 8 varieties cultivated in 8 localities in 2003.

Recently, our laboratory demonstrated that human neuroblastoma cells (SH-SY5Y) are capable of synthesizing morphine, the major active metabolite of opium poppy. Now our experiments are further substantiated by extending the biochemical studies to the entire morphine pathway in this human cell line. L-[1,2,3-13C3]- and [ring-2',5',6'-2H3]dopa showed high isotopic enrichment and incorporation in ...

This work represents a new attempt to use drone aerial photography detect illegal cultivation of opium poppy. The key this task is the precise segmentation poppy plant from captured image. To achieve mask close real data, it necessary extract target areas according different morphological characteristics and reduce complex environmental interference. Based on RGB images, plants, weeds, backgrou...

This paper seeks to demonstrate that, in Mexico, the policy of eradication poppy crops has not only been motivated by its official reason, anti-drug fight, but also instrumentalized for militarization certain regions counterinsurgent purposes, that is, deal with guerrilla activity. Of an empirical nature, this demonstration is based on a mixed methodology, both quantitative and qualitative, as ...

abstract benzylisoquinoline alkaloids are a diverse group of nitrogenous compounds which is found in about 20% of plant species. isolation of effective genes involved in morphine biosynthesis of opium poppy is very important in the production of specific which can be achieved using metabolic engineering techniques. in this biosynthesis pathway, the key enzyme sat is involved in the conversion o...

'The great appear great, because we are on our knees. Let us rise!,' wrote Larkin. Jean Faugier ( 1 ) described the 'tall poppy syndrome' and spoke of 'bold, nonconformist', brightly- coloured flowers being chopped down mercilessly by farmers just because they were different and stood above the rest in the wheatfields.

rather than of folic acid. Absorption of vitamin B12 was at the lower limit of normal and was improved by intrinsic factor. However, the absorption was higher than that found in pernicious anaemia, and the presence of free acid in the gastric juice and the normal appearance of the gastric mucosa do not confirm this diagnosis. The marginal absorption of vitamin B12 was probably a factor in the d...

A microplot study under field conditions was carried out during 2 consecutive years to assess the effect of root-knot nematode infection (2,000 Meloidogyne incognita eggs/kg soil) on three winter ornamental plants: hollyhock (Althea rosea), petunia (Petunia hybrida), and poppy (Papaver rhoeas). Effects of root-dip treatment with the biocontrol agents Pochonia chlamydosporia, Bacillus subtilis, ...
