All-Tunicate Cellulose Film with Good Light Management Properties for High-Efficiency Organic Solar Cells

open access: yesNanomaterials, 2023
Tunicate nanocellulose with its unique properties, such as excellent mechanical strength, high crystallinity, and good biodegradability, has potential to be used for the preparation of light management film with tunable transmittance and haze. Herein, we

Typical 2-Cys Peroxiredoxins as a Defense Mechanism against Metal-Induced Oxidative Stress in the Solitary Ascidian Ciona robusta

open access: yesAntioxidants, 2021
Typical 2-Cys peroxiredoxins (2-Cys Prdxs) are proteins with antioxidant properties belonging to the thioredoxin peroxidase family. With their peroxidase activity, they contribute to the homeostatic control of reactive oxygen species (ROS) and, therefore,

Tunicate gastrulation [PDF]

open access: yes, 2020
Tunicates are a diverse group of invertebrate marine chordates that includes the larvaceans, thaliaceans, and ascidians. Because of their unique evolutionary position as the sister group of the vertebrates, tunicates are invaluable as a comparative model and hold the promise of revealing both conserved and derived features of chordate gastrulation ...

Stemness Activity Underlying Whole Brain Regeneration in a Basal Chordate

open access: yesCells, 2022
Understanding how neurons regenerate following injury remains a central challenge in regenerative medicine. Adult mammals have a very limited ability to regenerate new neurons in the central nervous system (CNS). In contrast, the basal chordate Polycarpa

Diversity, Bioactivity Profiling and Untargeted Metabolomics of the Cultivable Gut Microbiota of Ciona intestinalis

open access: yesMarine Drugs, 2020
It is widely accepted that the commensal gut microbiota contributes to the health and well-being of its host. The solitary tunicate Ciona intestinalis emerges as a model organism for studying host–microbe interactions taking place in the gut, however ...

Unmanned truck transportation scheduling in open-pit mines based on improved tunicate swarm algorithm

open access: yesGong-kuang zidonghua, 2022
In order to solve the problem of unmanned truck transportation scheduling in open-pit mines, the minimum sum of fuel cost, fixed start-up cost, breakdown maintenance cost, and network base station construction and maintenance cost are taken as the ...

Tunicates [PDF]

open access: yesCurrent Biology, 2016
Tunicates, also called urochordates, are an extremely diverse subphylum of the Chordata, a phylum that also contains the vertebrates and cephalochordates. The tunicates seem to have undergone especially rapid evolution: while remaining exclusively marine, they have radiated to occupy habitats ranging from shallow water, to near shore to the open ocean ...

Fibronectin contributes to notochord intercalation in the invertebrate chordate, Ciona intestinalis

open access: yesEvoDevo, 2016
Background Genomic analysis has upended chordate phylogeny, placing the tunicates as the sister group to the vertebrates. This taxonomic rearrangement raises questions about the emergence of a tunicate/vertebrate ancestor.

Divergent mechanisms regulate conserved cardiopharyngeal development and gene expression in distantly related ascidians

open access: yeseLife, 2014
Ascidians present a striking dichotomy between conserved phenotypes and divergent genomes: embryonic cell lineages and gene expression patterns are conserved between distantly related species. Much research has focused on Ciona or Halocynthia spp.

Functional specialization of Aurora kinase homologs during oogenic meiosis in the tunicate Oikopleura dioica

open access: yesFrontiers in Cell and Developmental Biology, 2023
A single Aurora kinase found in non-vertebrate deuterostomes is assumed to represent the ancestor of vertebrate Auroras A/B/C. However, the tunicate Oikopleura dioica, a member of the sister group to vertebrates, possesses two Aurora kinases (Aurora1 and
