ParaHox Genes Revisited: From Gut Patterning to Integrated Axial and Neural Organization in Rotifera
Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 346, Issue 4, Page 357-369, June 2026.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.

Metabolic Properties of the Regions of the Amphibian Gastrula
Experimental Biology and Medicine, 1938 A number of authors have investigated the oxygen consumption and carbon dioxide production of the amphibian embryo at various stages of its development, with results of considerable interest. But such investigations throw no light upon the properties of the individual regions of the embryo at various stages, although the work of experimental ...

Migrasomes, Matrix‐Bound Nanovesicles, and More: Messengers in the Matrix
PROTEOMICS, Volume 26, Issue 6, Page 9-21, June 2026.ABSTRACT Extracellular vesicles (EVs) and particles (EPs) are diverse micro‐ and nanoparticles that circulate in bodily fluids and can attach to, or be deposited onto, the extracellular matrix (ECM) and other surfaces. To date, the nomenclature and classification of matrix‐bound or matrix‐associated EVs and EPs (MEVPs) have been unclear, largely due to

Internalized Evolutionary Inertia on Body Plan Evolution
Evolution &Development, Volume 28, Issue 2, June 2026.Animal development appears to intrinsically bias phenotypic evolution, though the exact mechanism is unclear. This review discusses potential mechanisms by which animal embryogenesis limits phenotypic diversification and considers whether inherent evolutionary inertia could allow us to predict future evolutionary paths.

Journal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.Abstract This study evaluated hatching rate, survival, osmolality, hematological and histopathological parameters to identify the optimal salinity of golden rabbitfish (Siganus guttatus) at three life stages: embryonic, pre‐feeding larvae, and juvenile.

Oxygen Consumption of the Parts of the Amphibian Gastrula.
Experimental Biology and Medicine, 1939 Interest in the organizer has led to the determination of its oxygen consumption and the results of various investigators do not agree. Braehet,1 Braehet and Shapiro,2 and Fischer and Hartwig,3 agree that the dorsal lip exhibits a higher rate, while Waddington, Needham and Brachet,4 and Boell and Needham5 report that the rates of O2 consumption of the ...
