Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...

Programmed oocyte retrieval.

open access: yesClinical and experimental obstetrics & gynecology, 1993
Several methods of facilitating the work schedule for in vitro fertilization programs have been proposed. LH-RH agonists offer the possibility of manipulating the day of hCG injection and consequently the day of ovum pick-up. Moreover, after desensitization, follicles are contemporarily stimulated and a higher number of mature oocytes are retrieved ...

Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

ParaHox Genes Revisited: From Gut Patterning to Integrated Axial and Neural Organization in Rotifera

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In rotifers, ParaHox genes show a dispersed genomic organization, with Xlox absent across gnathiferans. Exclusive neuronal expression of Gsx and Cdx reveals that ancestral ParaHox genes coordinated neural and epithelial development beyond gut patterning, suggesting an integrated role in early bilaterian body plan organization.

Comparative analysis of microRNAs in bovine colostrum and neonatal calf blood

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND MicroRNAs (miRNAs) are short non‐coding RNAs that participate in a wide range of biological processes. MiRNAs are present in high concentrations in colostrum, and these may be potentially transferred to newborn calves being fed colostrum.

The Oocyte/Antral Follicle Count Index: Does Maximizing Oocyte Yield Translate into Better Assisted Reproductive Technology Outcomes?

open access: yesJournal of Ultrasound in Medicine, EarlyView.
Objectives Whether aspiration of more oocytes than the antral follicle count (AFC) is beneficial for the current and future products of assisted reproductive technologies (ART) cycles. Methods Data of the first oocyte aspiration for intracytoplasmic sperm injection performed between 2018 and 2022 in attempt to conceive (ICSI, n = 399) or for planned ...
