Trichome dynamics and artemisinin accumulation during development and senescence of Artemisia annua leaves.
The results suggest that a (putative) intermediate such as dihydroartemisinic acid hydroperoxide temporarily may have accumulated in considerable quantities in artemisinin accumulation during the development of individual leaves. Expand

Investigation of the association between the NQO1 C609T polymorphism and esophageal adenocarcinoma in consecutive series of individuals that have undergone esophagectomy without prior radioor chemotherapy at the Technical University of Munich, which is one of the largest centers for esophages cancer surgery in the Western world.

Primary structure of copper-zinc superoxide dismutase from Neurospora crassa.
The invariant amino acids Pro 74 and Asp 76 of the four vertebrate and yeast superoxide dismutases were found to be substituted by arginine and alanine, respectively, in the Neurospora enzyme, showing a high degree of sequence homology among the six enzymes. Expand
Lack of photosensitization of ocular tissues by allopurinol.
It is concluded that patients in whom cataracts developed after using allopurinol and exposure to high irradiances of near UV light were most likely affected by the UV light itself. Expand
Sub-threshold near-UV radiation effects on aphakic guinea pig retinas.
It is demonstrated that ambient near-UV light exposure can adversely influence retinal electrical activity in aphakic eyes at irradiance levels below threshold for morphological damage and the protective function of the lens is supported. Expand
Modelling processes determining and limiting the production of secondary metabolites during crop growth : the example of the antimalarial artemisinin produced in Artemisia annua
A new, simple, model for explaining variation in artemisinin yield based on leaf and trichome production in combination with biosynthesis of artemis inin is proposed. Expand
QUANTITATIVE STUDIES ON TRANSLOCATION IN SAGITTARIA GRAMINEA MICHX. LEAVES, A NEW METHOD OF MEASUREMENT
- E. Schenk
- 1 June 1972
The results obtained so far indicate a polar, non-specific translocation process, in which the metabolic role of the translocated amino acid seems of minor importance. Expand
SIMILAR EFFECTS OF CYTOKININS AND CARBONYL CYANIDE m-CHLOROPHENYLHYDRAZONE (CCCP) ON AMINO ACID TRANSLOCATION IN LEAVES OF SAGITTARIA GRAMINEA MICHX
- E. Schenk
- 1 October 1974
SUMMARY Kinetin, zeatin or zeatin riboside applied to parts of excised leaves of Sagittaria graminea change the distance profile of 14C-α-amino-iso-butyric acid translocation in these leaves. They… Expand
THE EFFECTS OF CYCLOHEXIMIDE ON THE UPTAKE AND TRANSLOCATION OF AMINO ACIDS IN LEAVES OF SAGITTARIA GRAMINEA MICHX
- E. Schenk
- 1 February 1976
SUMMARY Cycloheximide (CHM) inhibits translocation of 14C-α-amino-iso-butyric acid in excised leaves of Sagittaria graminea, but does not affect its uptake. Protein synthesis was also inhibited by… Expand
