Pore-linked filaments in anura spermatocyte nuclei
Anais da Academia Brasileira de Ciências, 2007 Pore-linked filaments were visualized in spreads of anuran spermatocyte nuclei using transmission electron microscope. We used Odontophrynus diplo and tetraploid species having the tetraploid frogs reduced metabolic activities.

Green2/3 dot stretching in an early Cap-H2cc3/ Df spermatocyte.
, 2021 Cap-H2cc3/ Df spermatocytes with bam>UASt-RedX Green2/3 were analyzed by time-lapse imaging at 60 sec intervals. The stretching of a Green2/3 dot, as observed in the spermatocyte presented in Fig 6E, is shown in a maximum intensity projection.

Environmental Toxicology, EarlyView.ABSTRACT Mining plays a crucial role in economic development, but improper management can lead to severe environmental degradation. Particularly for iron ore, mining generates vast amounts of tailings often stored in unstable dams. This study aims to investigate the toxicological impacts of environmentally relevant concentrations of metals mixture ...

Cytogenotoxic and Molecular Assessment of Pyrethrins on Non‐Target Allium cepa Roots
Environmental Toxicology, EarlyView.ABSTRACT The pyrethrins, which form a part of naturally occurring insecticidal chemicals derived from chrysanthemum flowers, not only provide rapid knockdown of a broad spectrum of insect pests but are also widely used in integrated pest management due to a generally favorable safety profile, largely attributed to low mammalian toxicity.

Silver-negative NORs in Pamphagus ortolaniae (Orthoptera: Pamphagidae)
European Journal of Entomology, 2008 The present paper reports some cytogenetic peculiarities observed in the Ag-NORs of Pamphagus ortolaniae chromosomes, the unusual behaviour of ribosomal sites after silver staining and the intense Ag-positive reaction of centromeric regions at ...

, 2022 Conserved PUF (Pumilio and FBF) proteins repress the translation by binding to its target mRNA 3' untranslated region (3'UTR). C. elegans has 11 PUF proteins. Among them, we focused on two FBFs (FBF-1 and FBF-2) and PUF-8.
