Isozyme variation in Silene pratensis: a response to different environments

Differential Regulation of Flavone Glycosylation during Ontogeny of Silene pratensis

Two isovitexin glycosides have been found in the cotyledons and foliage leaves o f Silene pratensis plants that are unable to glycosylate isovitexin in their petals (genotype gg glgl fgfg). The glycosides (isovitexin 7-O -galactoside and isovitexin 7-O -galactose 2 " -0 -a rab in o sid e ) were present only in the lower leaves: leaves p roduced later in the developm ent o f the flower stem accu...

Heliospheric Response to Different Possible Interstellar Environments

At present, the heliosphere is embedded in a warm low density interstellar cloud that belongs to a cloud system flowing through the local standard of rest with a velocity near ∼18 km s. The velocity structure of the nearest interstellar material (ISM), combined with theoretical models of the local interstellar cloud (LIC), suggest that the Sun passes through cloudlets on timescales of ≤ 10–10 y...

Variation in the response of barley cultivars to nirrogen fertilizer

Response of dupuytren fibroblasts to different oxygen environments.

PURPOSE It is thought that local ischemia and oxygen radicals are responsible for fibroblast-to-myofibroblast cell transformation and proliferation. We hypothesized that hypoxia could differentially activate the contractility of fibroblasts from normal human palmar fascia and from fibroblasts-myofibroblasts of Dupuytren cords. METHODS Normal palmar fascia from 5 patients with carpal tunnel sy...
