Cytogenetical and histochemical studies on curcumin in male rats

Curcumin is a major component of the curcuma species, commonly used as a yellow coloring and flavoring agent in foods. Curcumin has been demonstrated to have potent antioxidant, anti-inflammatory activity and has shown anticancer properties in many rodent models. There is the perception that since compounds are natural, they are devoid of toxicity and safe to use. Some of the active compounds i...

Cytogenetical studies in five Atlantic Anguilliformes fishes

The order Anguilliformes comprises 15 families, 141 genera and 791 fish species. Eight families had at least one karyotyped species, with a prevalence of 2n = 38 chromosomes and high fundamental numbers (FN). The only exception to this pattern is the family Muraenidae, in which the eight species analyzed presented 2n = 42 chromosomes. Despite of the large number of Anguilliformes species, karyo...

STUDIES ON THE CARYOLOGY OF SOME SPECIES OF THE GENUS SUAEDA (CHENOPODIACEAE) IN IRAN

Caryological studies were carried out on ten species of the genus Suaeda belonging to 27 samples of different populations in Iran. Important chromosome features including numbers, lengths, centromere locations and caryotypes were studied. All the species have basic chromosome numbers of x=9. Chromosome counts of S. acuminata (C.A.Mey.) Moq. (2n=18), S. aegyptiaca (Hasselq.) Zoh., (2n=l8)...
