Trace metal extraction and biomass production by spontaneous vegetation in temporary Mediterranean stormwater highway retention ponds: Freshwater macroalgae (Chara spp.) vs. cattails (Typha spp.)

, 2015
International audienceA field study on the capacity of spontaneous vegetation of four motorway ponds to extract four trace metals (Cd, Cu, Zn and Pb) was carried out. High biomasses (ca. 400 g m (2) DW) of freshwater macroalgae Chara spp.

Cytochemical studies on histone-type and protamine-type proteins during spermiogenesis in Chara vulgaris and Chara tomentosa.

Folia histochemica et cytobiologica, 2003
Comparative studies concerning detection of histone-type and protamine-type proteins were carried out on Chara species (C. vulgaris, C. tomentosa). Analysis of antheridia during spermiogenesis (stages I-X) of both Charta species showed very similar staining patterns obtained after reactions revealing the examined proteins. Cytochemical studies showed a

THE ASSESSMENT OF THE SPIROGYRA VARIANS AND CHARA VULGARIS COMPARATIVE AND COMBINED ANTIOXIDANT POTENTIAL

Journal of Medical & Health Sciences Review
Oxidative stress (OS) is a common mechanism of tissue destruction in vivo that has been implicated in the origin and impact of numerous diseases. The rising incidence of cancer can now be explained in two ways: first, by environmental contaminants; and second, by lifestyle choices including smoking, drinking, and eating.

RER and protamine-type proteins during Chara tomentosa L. spermiogenesis

, 2003
In Chara tomentosa during mid spermiogenesis (phases V, VI, VII) when the amount of nuclear protamine-type proteins increases, while the amount of histones decreases, in connection with chromatin remodelling, an extensive RER system filled with dark ...

The influence of epoxomicin, inhibitor of proteasomal proteolytic activity, on spermiogenesis in Chara vulgaris.

Folia histochemica et cytobiologica, 2003
The influence of 48-h treatment with epoxomicin, an inhibitor of proteolytic activity of proteasomes, at the concentration 10 microM, on spermiogenesis in algae Chara vulgaris was examined. In the presence of the inhibitor, the frequency of early spermiogenesis phases significantly increased, the number of spermatids in mid-phases decreased and ...

Changes in ultrastructure of cytoplasm and nucleus during spermiogenesis in Chara vulgaris.

Folia histochemica et cytobiologica, 1996
In the present study much attention was paid to the first and middle stages of spermiogenesis in Chara vulgaris. The spermiogenesis was divided into 8 phases (A-H). In telophase leading to spermatid formation (A phase) there are no structural changes, indicating that cells pass into a new functional stage-spermiogenesis.B phase: After the formation of ...
