Micronucleus of Epistylis

Macronuclear Regeneration in Epistylis articulata

The reorganization of the macronucleus from the vegetative micronucleus is described in Epistylis articulata (Ciliophora, Peritricha). Individuals which have accidentally been deprived of a macronucleus during binary fission develop a new one from the micronucleus. In such amacronucleate animals, the micronucleus divides into two, one of them growing into a macronucleus, the other remaining as ...

Micronucleus Test of Mofezolac

---・-A micronucleus test using BDFi male mice was conducted in order to evaluate the in vive mutagenicity of mofezolac (N-22). N-22 was orally administered at doses of 75, 150, 300 arid 600 mglkg, with a sampling time of 24 hr. The frequency of polychromatic erythrocytes with micronuclei was O,07-O,08% in the groups treated with N-22 and did not differ markedly from that of the vehicle control ...

Association of micronucleus frequency with neurodegenerative diseases.

Micronuclei (MNi) can originate either from chromosome breakage or chromosome malsegregation events and are therefore ideal biomarkers to investigate genomic instability. Studies in peripheral lymphocytes of patients with neurodegenerative diseases, mainly Alzheimer's disease (AD) and Parkinson's disease (PD), revealed an increased micronucleus (MN) frequency in both disorders but originating m...

Description of Epistylis riograndensis n.sp. (Ciliophora: Peritrichia) found in an artificial lake in Southern Brazil.

Epistylis riograndensis n. sp., a freshwater peritrich hosting symbiotic algae in its cytoplasm, was collected from an artificial lake, in a Botanical garden in Southern Brazil. Its detailed morphology was investigated using live and silver-stained specimens. The colonial sessile E. riograndensis has elongate zooids measuring, on average, 162 μm in length and 45 μm in width. A single contractil...
