Amniotic Mesenchymal Stromal/Stem Cell–Derived Extracellular Vesicles for Equine Chronic Degenerative Endometritis Treatment

open access: yesVeterinary Medicine and Science, Volume 12, Issue 2, March 2026.
Equine endometrium can develop progressive fibrotic and functional alterations, probably correlated with age and inflammatory insults that alter uterine microenvironment, creating hostile conditions for embryo implantation. Named chronic degenerative endometritis, this condition leads to reduced fertility in older mares. Extracellular vesicles secreted

Changes in Shell and Crystal Structure From Life to Sediments: An EBSD Characterization of Subantarctic Planktic Foraminifera

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Fossil foraminifera store a wealth of information about past climates and ecosystems in their shell chemistry. However, these element and isotope signals may be affected by post‐mortem diagenesis (i.e., alteration). Here, we use Electron Backscatter Diffraction (EBSD; crystal orientation mapping) to evaluate the structural integrity of sub ...

Mussel eggs as indicators of mutagen exposure in coastal and estuarine environments [PDF]

open access: yes, 1994
The aim of this study was to develop a short-term genotoxicity assay for monitoring the marine environment for mutagens. Based on the developing eggs and embryos of the marine mussel Mytilus edulis, an important pollution indicator species, the test ...

Pulsed Electric Fields for Emerging Single‐Cell Bioprocessing in Food Applications: Electropermeabilization Mechanisms and Design Principles

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 2, March 2026.
ABSTRACT This review evaluates pulsed electric fields (PEF) as an emerging platform for single‐cell bioprocessing in food applications. Connections are drawn between key mechanisms in electropermeabilization and applications, and a practical PEF process design framework is provided.

Immunostaining of P450c17, Aromatase and Oestrogen Receptor Alpha in Germ and Somatic Cells During Gonadal Development in Greater Rhea

open access: yesAnatomia, Histologia, Embryologia, Volume 55, Issue 2, March 2026.
ABSTRACT The greater rhea (Rhea americana), the largest bird species in South America, has significant economic value due to its meat, eggs, leather, feathers and oil. However, its lack of external sexual dimorphism poses challenges for reproductive management and breeding programmes.

TENT5-mediated polyadenylation of mRNAs encoding secreted proteins is essential for gametogenesis in mice

open access: yesNature Communications
Cytoplasmic polyadenylation plays a vital role in gametogenesis; however, the participating enzymes and substrates in mammals remain unclear. Using knockout and knock-in mouse models, we describe the essential role of four TENT5 poly(A) polymerases in ...

Novel improvement in iPSCs generation protocols through mouse gametogenesis epigenetic erasure mechanisms [PDF]

open access: yes, 2016
The main goal of this review is to describe gametogenesis epigenetic erasure mechanisms and to propose candidate molecules which can erase remaining epigenetic marks that enhace re-differentiation of cultured induced pluripotent stem cells (iPSCs) into ...

Spermatogenesis and Morphology of the Male Reproductive Tract of the Turtle Kinosternon scorpioides

open access: yesAnatomia, Histologia, Embryologia, Volume 55, Issue 2, March 2026.
ABSTRACT The scorpion mud turtle (Kinosternon scorpioides), a freshwater chelonian widely distributed in South and Central America, presents gaps in the microscopic and ultrastructural characterisation of its male reproductive system. This study provides a comprehensive characterisation of the testes, epididymides, and deferent ducts of adult males ...

INSL3 Expression in Leydig Cells is a Biomarker for Immunocastration in Boars: Transcriptional Evidence

open access: yesAndrology, Volume 14, Issue 3, Page 782-795, March 2026.
ABSTRACT Background Study aimed to obtain insights into physiological responses to immunocastration in pubertal boars by evaluating effects of alternative vaccination protocols and identifying a reliable immunocastration biomarker. Objectives It was hypothesized that the timing of gonadotropin‐releasing hormone (GnRH) suppression by immunocastration ...

Epigenetics in Captivity: Restoring Wild Phenotypes in Captive‐Reared Salmonids

open access: yesEvolutionary Applications, Volume 19, Issue 3, March 2026.
ABSTRACT Captive rearing is a common practice for the stocking, conservation, and supplementation of fish species worldwide, but captive‐reared fish can exhibit altered phenotypes leading to reduced fitness in nature compared to wild conspecifics. In salmonids, certain studies have found limited genetic differentiation between wild and captive‐reared ...
