Última A study of the constitutive heterochromatin and nucleolus organizer regions of Isocopris inhiata and Diabroctis mimas (Coleoptera: Scarabaeidae, Scarabaeinae) using C-banding, AgNO3 staining and FISH techniques Genet. Mol. Biol. Bione,Edgar; Camparoto,Marjori Leiva; Simões,Zilá Luz Paulino. Meiotic and mitotic chromosomes of Isocopris inhiata and Diabroctis mimas were studied by standard staining procedures, C-banding, silver nitrate staining and FISH using Apis mellifera 28S rDNA as probe. Isocopris inhiata presented a 2n = 18 (8II+ Xy p) karyotype, composed of meta-submetacentric chromosomes with gradual reduction in size. The karyotype of D. mimas was 2n = 20 (9II+ Xy p), composed of meta-submetacentric (pairs 1, 2, 3, 4 and 7) and acrocentric (pairs 5, 6, 8 and 9) chromosomes, with gradual reduction in size. Analysis of constitutive heterochromatin revealed similar C-banding patterns for both species, showing pericentromeric and telomeric bands and diphasic chromosomes. In addition, the X chromosomes of these species were found to be... Tipo: Info:eu-repo/semantics/article Palavras-chave: Coleoptera; Heterochromatin; NORs; FISH.

Mol. Biol. Teixeira,Rosangela de Oliveira; Camparoto,Marjori Leiva; Mantovani,Mário Sérgio; Vicentini,Veronica Elisa Pimenta. The use of medicinal plants by the general population is an old and still widespread practice, which makes studies of their genotoxicity essential. Psidium guajava L. and Achillea millefolium L. are examples of plants commonly used in popular medicine. P. guajava L. is indicated for diarrhea and also as an antiseptic, while A. millefolium L. is indicated as an analgesic, antispasmodic, digestive, diuretic, antiseptic, astringent, emollient, wound healer and hemorrhoid medication. The aim of this study was to determine the effects of the infusions of these two plant species on chromosomes and the cell cycle. Leaves from the plants were used to prepare infusions, in the same manner as teas, but at two different concentrations. Allium cepa L. root-tip cells...

Ano: 2003 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1415-47572003000400021 Effects of Maytenus ilicifolia Mart. and Bauhinia candicans Benth infusions on onion root-tip and rat bone-marrow cells Genet. Mol. Biol. Camparoto,Marjori Leiva; Teixeira,Rosangela de Oliveira; Mantovani,Mário Sérgio; Vicentini,Veronica Elisa Pimenta. Medicinal plants are widely used to treat various diseases, and in Brazil the plants Maytenus ilicifolia Mart. and Bauhinia candicans Benth are commonly used in popular medicine. However, there are a large number of compounds in plants which can produce alterations in genetic material, and this study was conducted to investigate any possible mutagenic and cytotoxic effects that M. ilicifolia and B. candicans infusions may have on the cell cycle and chromosomes. Infusions were prepared with in natura leaves to give two concentrations of infusions, one at the concentration normally used by the population in general and the other at 10 times this value (i.e. 3.5 and 35 mg/mL for M. ilicifolia and 0.465 and 4.65 mg/mL for B. candicans). Onion (Allium cepa L.)...
