Neuronal sources of hedgehog modulate neurogenesis in the adult planarian brain

open access: yeseLife, 2016
The asexual freshwater planarian is a constitutive adult, whose central nervous system (CNS) is in a state of constant homeostatic neurogenesis. However, very little is known about the extrinsic signals that act on planarian stem cells to modulate rates ...

Evidence of novel type of ribosome in eukaryotic intermediate flatworm [PDF]

open access: yes, 2008
In all organisms, messenger-directed protein synthesis is catalyzed by ribonucleoprotein particles called ribosomes. A ribosome is typically composed of one small and one large subunit which contain one short (18S) and one long (28S) rRNAs, respectively.

Plant‐Derived Treatments for Monogenean Parasites in Farmed Fish: A Systematic Review and Meta‐Analysis

open access: yesReviews in Aquaculture, Volume 18, Issue 3, June 2026.
ABSTRACT Monogeneans are among the most problematic ectoparasites in finfish aquaculture. Plant‐derived compounds have been widely explored as therapeutic agents, yet their efficacy and safety have not been quantitatively synthesized across studies. This study provides a meta‐analysis of plant‐based treatments against monogeneans, integrating 453 in ...

Phloxine B Staining is Compatible With High‐Throughput DNA Barcoding of Meiofauna

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Modern, integrative biodiversity research requires methods capable of bridging the gap between detailed morphological observations and the scalability of DNA sequencing. For small, transparent, and highly abundant animals like meiofauna, sorting specimens from the matrix forms a major bottleneck, as the use of commonly used stains can inhibit ...
