Planarians as a model to assess in vivo the role of matrix metalloproteinase genes during homeostasis and regeneration [PDF]

open access: yes, 2013
Matrix metalloproteinases (MMPs) are major executors of extracellular matrix remodeling and, consequently, play key roles in the response of cells to their microenvironment.

Recycling Subducted Organic Carbon as Diamonds: An Example From the New Caledonia Forearc Ophiolite

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 4, April 2025.
Abstract Micro‐diamonds and moissanite (SiC) have been identified in ophiolitic mantle harzburgites and chromitites of the New Caledonian Peridotite Nappe. The pale yellow (100–250 μm) micro‐diamonds and light blue moissanite (mean −26.5‰, range −33.5‰ to −23.8‰ and mean −26.9‰, range −31.8‰ to −25.6‰ respectively) exhibit consistently strong negative ...

A mex3 homolog is required for differentiation during planarian stem cell lineage development

open access: yeseLife, 2015
Neoblasts are adult stem cells (ASCs) in planarians that sustain cell replacement during homeostasis and regeneration of any missing tissue. While numerous studies have examined genes underlying neoblast pluripotency, molecular pathways driving ...

Profiling G protein-coupled receptors of Fasciola hepatica identifies orphan rhodopsins unique to phylum Platyhelminthes [PDF]

open access: yes, 2017
G protein-coupled receptors (GPCRs) are established drug targets. Despite their considerable appeal as targets for next-generation anthelmintics, poor understanding of their diversity and function in parasitic helminths has thwarted progress towards GPCR-

The Ronda Peridotite: Garnet-, Spinel-, and Plagioclase-Lherzolite Facies and the P-T Trajectories of a High-Temprature Mantle Intrusion [PDF]

open access: yes, 2017
The Ronda peridotite is a high-temperature, alpine-type peridotite emplaced in the internal Zone of the Betic Cordilleras, southern Spain. Using the mineral assemblages of the peridotite and mafic layers, the peridotite mass has been subdivided into 4 ...

Adult stem cell plasticity: Neoblast repopulation in non-lethally irradiated planarians

open access: yesDevelopmental Biology, 2009
Planarians are a model system for studying adult stem cells, as they possess the neoblasts, a population of pluripotent adult stem cells able to give rise to both somatic and germ cells. Although over the last years several efforts have been made to shed light on neoblast biology, only recent evidence indicate that this population of cells is ...

A Rare Glimpse of Paleoproterozoic Sub‐Arc Mantle: The Ussuit Peridotite, West Greenland

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 3, March 2025.
Abstract Mantle residues beneath Archean cratonic nuclei have been extensively studied, whereas less attention has been given to the mantle lithosphere beneath Proterozoic mobile belts that link these nuclei. Rare mantle tectonites within tectonic mélanges of Paleoproterozoic mobile belts provide information important to understanding the broader ...

Variable Upper Mantle Geochemical Processes Constrained From Independent Component Analysis of the Fizh Massif, Northern Oman Ophiolite

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 3, March 2025.
Abstract We statistically analyzed the whole‐rock compositions of peridotites in the Oman ophiolite using a multivariate statistical technique called independent component analysis (ICA) to better understand the processes within the ophiolitic mantle section that gave rise to the compositional variations, including partial melting, mantle–melt ...
