ParaHox Genes Revisited: From Gut Patterning to Integrated Axial and Neural Organization in Rotifera

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
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.

Chimerism a natural ability to tolerate kin, evolutionary traits connecting mammalian and protochordates [PDF]

open access: yesInvertebrate Survival Journal, 2009
In the middle of the 20th century, Owen (1945, 1954) and Billingham et al. (1953) immunological studies suggested that fetal exposure to foreign antigens during pregnancy induce immunologic tolerance in the fetus. Recently, Mold et al.

IDENTIFICATION OF SECONDARY METABOLITE COMPOUNDS IN TUNICATE (Polycarpa aurata) ASSOCIATED BACTERIA

open access: yesJurnal Kedokteran Diponegoro, 2021
Background: Marine biodiversity in the last few decades has been explored and utilized as marine natural products. The secondary metabolites produced by marine organisms are utilized by humans in various aspects of life.

The effects of single versus successive warm summers on an intertidal community

open access: yesOikos, EarlyView.
To accurately predict how organisms and ecological communities will respond to future conditions caused by climate change, we must consider the temporal dynamics of environmental stressors, including the effects of repeated exposures to stress. We performed a two‐year passive thermal manipulation in coastal British Columbia, Canada to determine how ...

The Genome of the “Sea Vomit” Didemnum vexillum

open access: yesLife, 2021
Tunicates are the sister group of vertebrates and thus occupy a key position for investigations into vertebrate innovations as well as into the consequences of the vertebrate-specific genome duplications.

Immunotoxicity of butyltins in tunicates

open access: yesApplied Organometallic Chemistry, 1995
This study was designed to investigate the effects of butyltins on yeast phagocytosis in vitro by haemocytes of the colonial ascidian Botryllus schlosseri. This species has been reported to be very sensitive to organotins. Results show that, in analogy to reports on mammalian leukocyte reactivity, butyltins exert inhibitory effects on phagocytosis in a

Constituintes químicos da ascídia didemnum psammatodes (sluiter, 1895) coletada na costa cearense Chemical constituent from the ascidian didemnum psammatodes (sluiter, 1895) collecter on the shores of ceara state

open access: yesQuímica Nova, 2007
Chemical investigation of the methanolic extract of the ascidian Didemnum psammatodes has led to the identification of the nucleosides 2'-deoxyuridine (1), thymidine (2), 2'-deoxyinosine (3) and 2'-deoxyguanosine (4), the steroids cholestanol ...

Incorporating environmental DNA metabarcoding for improved benthic biodiversity and habitat mapping

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Seafloor imagery is commonly used to collect information about the distribution of benthic organisms in order to generate habitat and biodiversity maps. Recent advances in genomics (e.g., environmental DNA; eDNA) show potential to complement video surveys for habitat mapping, but there have been few examples testing this.

Cabomba caroliniana and Schoenoplectus californicus as Antifouling Candidates: Anti‐Attachment and Toxicological Effects in Aurelia coerulea (Cnidaria, Scyphozoa)

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Biofouling on artificial surfaces in aquatic ecosystems leads to significant economic losses. Current antifouling paints, while effective, often harm the aquatic environment. This study explores ecologically safe antifouling alternatives derived from plants, focusing on the aquatic macrophytes Cabomba caroliniana (CC) and Schoenoplectus ...
