A forkhead transcription factor is wound-induced at the planarian midline and required for anterior pole regeneration. [PDF]

PLoS Genetics, 2014
Planarian regeneration requires positional information to specify the identity of tissues to be replaced as well as pluripotent neoblasts capable of differentiating into new cell types. We found that wounding elicits rapid expression of a gene encoding a

Reactive Melt Flow in the Continental Arc Root: Insights for the Transition From Gabbronorite to Garnet Granulite in the Central Qilian Belt, NE Tibet

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 9, September 2025.
Abstract Understanding reactive melt flow is crucial for advancing our knowledge of crustal differentiation; however, the mechanisms governing melt migration remain debated, particularly in deep magmatic arc environments. A composite sample from the Central Qilian continental arc, NE Tibet, preserves the transition from hornblende gabbronorite to ...

Gtdap-1 and the role of autophagy during planarian regeneration and starvation [PDF]

, 2007
Planarians have been established as an ideal model organism for stem cell research and regeneration. Planarian regeneration and homeostasis require an exquisite balancing act between cell death and cell proliferation as new tissues are made (epimorphosis)

Radioisotopic age constraints of the Cambrian Ritland impact structure, Norway

Meteoritics &Planetary Science, Volume 60, Issue 9, Page 2223-2238, September 2025.
Abstract Secondary ion mass spectrometry U‐Pb geochronology has been performed on zircon grains separated from impact melt rock from the 2.7 km‐in‐diameter Ritland impact structure, southwestern Norway. Scanning electron microscope‐based imaging techniques, including electron backscatter diffraction analysis, reveal various zircon grain microtextures ...

The in vivo transcriptome of Schistosoma mansoni in the prominent vector species Biomphalaria pfeifferi with supporting observations from Biomphalaria glabrata. [PDF]

, 2019
BackgroundThe full scope of the genes expressed by schistosomes during intramolluscan development has yet to be characterized. Understanding the gene products deployed by larval schistosomes in their snail hosts will provide insights into their ...

Specific NuRD components are required for fin regeneration in zebrafish [PDF]

, 2014
Background: epimorphic regeneration of a missing appendage in fish and urodele amphibians involves the creation of a blastema, a heterogeneous pool of progenitor cells underneath the wound epidermis. Current evidence indicates that the blastema arises by

Landmarks in Existing Tissue at Wounds Are Utilized to Generate Pattern in Regenerating Tissue [PDF]

, 2017
Regeneration in many organisms involves the formation of a blastema, which differentiates and organizes into the appropriate missing tissues. How blastema pattern is generated and integrated with pre-existing tissues is a central question in the field of

Oxide Gabbros: Transformation From Oceanic Ridge‐Transform Systems to Subduction

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 7, July 2025.
Abstract Fluid composition and fluxes in subduction zones are primarily governed by the nature and degree of hydrothermal alteration of the subducting oceanic lithosphere. However, spatial and temporal heterogeneities inherited from mid‐ocean ridge and oceanic transform fault (OTF) systems introduce significant uncertainties in constraining these fluid

Dual functions of Macpiwi1 in transposon silencing and stem cell maintenance in the flatworm Macrostomum lignano [PDF]

, 2015
PIWI proteins and piRNA pathways are essential for transposon silencing and some aspects of gene regulation during animal germline development. In contrast to most animal species, some flatworms also express PIWIs and piRNAs in somatic stem cells, where ...
