Linking Chordate Gene Networks to Cellular Behavior in Ascidians [PDF]

open access: yes, 2006
Embryos of simple chordates called ascidians (sea squirts) have few cells, develop rapidly, and are transparent, enabling the in vivo fluorescent imaging of labeled cell lineages. Ascidians are also simple genetically, with limited redundancy and compact

Rotenone Induces Morphological Damage and Reduction in Catecholamine Levels in the Central Nervous System of the Ascidian Styela plicata

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Ascidians are invertebrates that occupy a key phylogenetic position as a sister group of the vertebrates. The organization of their central nervous system (CNS), with cortex and medulla, indicates a plesiomorphic character of the gray and white matter of vertebrates, making this group of animals useful for studies of neurodegenerative events ...

Real‐world insights on switching aflibercept dosage for enhanced outcomes in age‐related macular degeneration (RISE‐AMD): Safety data

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose To evaluate real‐world safety experience with aflibercept 8 mg in a large case series of patients with neovascular age‐related macular degeneration (nAMD). Methods Due to a high proportion of patients on short treatment intervals, patients with nAMD at a Danish tertiary retina clinic were systematically switched to aflibercept 8 mg ...

Depth-wise variations in biofouling community development on aquaculture cage nets in the Red Sea

open access: yesEgyptian Journal of Aquatic Research
This study examined the development of biofouling assemblages on cage net panels submerged at different depths in a fish farm in the Red Sea. Experimental rafts equipped with Dyneema fibre nets were submerged at depths of 5, 10 and 15  m.

Clinical manifestations of dual‐gene variants in retinitis pigmentosa

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose Retinitis pigmentosa (RP) is an inherited retinal disease (IRD), whereby each affected individual typically harbours pathogenic variants in a single causative gene, yet the disorder exhibits marked genetic heterogeneity, with more than 100 genes reported to underlie RP.

Ascidians and their distribution in the Mediterranean Sea [PDF]

open access: yes, 2006
This study was carried out elucidate Ascidian fauna and some ecological properties of shores of Bozcaada Island located in the North-east of the Aegean Sea. More than 2500 ascidians species are known to inhabit bottoms of the world's oceans.

The Embryonic Development of the Cotylean Polyclad Phrikoceros jannetae

open access: yesActa Zoologica, EarlyView.
ABSTRACT Polyclads exhibit distinct developmental modes ranging from direct to indirect development, with several transitional stages also recognised. The existence of an indirect developmental mode in polyclads with a planktonic life history stage in the form of a free‐swimming larva is unique among all free‐living flatworms and makes polyclads a ...

Antarctic ascidians under increasing sedimentation: Physiological thresholds and ecosystem hysteresis

open access: yes, 2021
Glacier melting sediment inputs affect coastal ecosystems on the Antarctic Peninsula. In Potter Cove (South Shetland Islands, Antarctica), the shift from an “ascidian dominated” to a “mixed” assemblage has been linked to sedimentation.

Protostigmata in ascidians [PDF]

open access: yesProceedings of the Royal Society of London. Series B, Containing Papers of a Biological Character, 1913
Abstract It has been showed that at a certain stage in the ontogeny of Ascidians there is usually a definite number of stigmata or gill slits, which are elongated dorsorventrally and arranged in a longitudinal series on each side of the pharynx. To these the name protostigmata was given by Garstang in 1892.

Characterization of dermatan sulfate and chondroitin sulfate profiles during brain regeneration in Styela plicata

open access: yesThe FEBS Journal, EarlyView.
Adult ascidians are capable of regenerating their entire brains following injury, and glycosaminoglycans have been shown to either promote or inhibit neuritogenesis. In this study, dermatan 2,6‐disulfate (D2,6S) was identified as the predominant complex carbohydrate in the ascidian brain.
