Increased Genetic Instability in Exfoliated Oral Cells in Patients With Epidermolysis Bullosa

open access: yesOral Diseases, EarlyView.
ABSTRACT Objective To analyze the nuclear abnormalities of cytotoxicity—karyorrhexis (KR), karyolysis (KL), and pyknosis (PN)—and genotoxicity—micronucleus (MN) in exfoliated cells from different sites of the oral mucosa in patients with Epidermolysis Bullosa (EB) and a control group.

Single‐Nucleus Transcriptome Analysis Provides New Insights Into B Chromosome Elimination in Sorghum

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT B chromosomes are supernumerary entities found in many plant species, with some exhibiting tissue‐specific elimination. In Sorghum purpureosericeum, extensive B chromosome elimination occurs during embryogenesis affecting most of the embryonic organs, leaving the B chromosome maintained mainly in limited regions of meristems.

Investigation of Toxic Effects of the Glyphosate on Allium cepa

open access: yesJournal of Agricultural Sciences, 2011
In the present study, toxic effects of glyphosate on Allium cepa L. (Amaryllidaceae) cells were investigated. For this aim, we used the germination percentage, root length, seedling weight, malondialdehyde (MDA) level, frequency of micronucleus (MN ...

New Considerations on Meiosis, Affinity and Genomic Constitution in Aneuploids and Interploid Hybrids of Urochloa P. Beauv. (Brachiaria)

open access: yesPlant Breeding, EarlyView.
ABSTRACT The combination of polyploidy, apomixis and the formation of aneuploid and interploid hybrids makes the genus Urochloa an interesting system for investigating meiotic stability and genome behaviour in grasses. In this study, routine meiotic analysis and genomic in situ hybridization (GISH) were used to (i) evaluate meiosis in three hybrids of ...

Nonrandom Localization of DNA Sequences in the Crescent Micronucleus of \u3cem\u3eTetrahymena\u3c/em\u3e

open access: yes, 1985
The premeiotic micronucleus of Tetrahymena thermophila elongates parallel to the long axis of the cell. In fixed cells one end of this crescent micronucleus appears thicker than the other, and either end may be oriented toward the anterior of the cell ...

Cellular Effects of Naringin in Prevention of Genotoxicity Caused by Mifepristone on Human Blood Lymphocytes

open access: yesJournal of Mazandaran University of Medical Sciences, 2018
Background and purpose: Mifepristone is an oral synthetic steroid with antiglucocorticoid and antiprogesterone activities. Therefore, it could be dangerous during pregnancy since it causes cytogenetic damage and, consequently, abortion.

Safety Assessment and Hypoglycemic Effect of Moringa oleifera Lam. Seed Lectin (WSMoL) in Alloxan‐Induced Diabetic Mice

open access: yesJournal of Applied Toxicology, Volume 46, Issue 11, Page 3973-3988, November 2026.
ABSTRACT Moringa oleifera Lam. seeds contain WSMoL, a lectin previously studied for toxicity and pharmacological effects. In this study, we investigated WSMoL (10, 25, or 50 mg/kg i.p.) for acute and 14‐day repeated‐dose toxicity, as well as genotoxicity, in Swiss mice.
