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...

Numbers and Distribution of Chromosome Knobs in United States Maize.

HE chromosomes of maize possess a number of distinguishing features T used by cytologists to identify members of the complement. Among the more important of these are the dark staining enlargements known as knobs, which have been shown to occur a t certain points and only a t certain points on the chromosomes. Although chromosome knobs are distinguishable in mitotic prophases they are best stud...

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...

CHROMOSOME STUDIES OF IRANIAN MEMBERS OF TRIBE SOPHOREAE (FAMILY LEGUMINOSAE

The tribe Sophoreae sensu Polhill [9,10] is a large and diverse assemblage comprising the ancient and primitive ancestral stocks of Papilionoideae. The most frequent chromosome basic numbers in this tribe are x = 11 and x = 9 but chromosome numbers range from x = 8-14 are also known. In this study chromosome numbers and karyotype variation of Iranian members of tribe Sophoreae are reported. Ira...
