Insights into Cytotoxic Behavior of Lepadins and Structure Elucidation of the New Alkaloid Lepadin L from the Mediterranean Ascidian Clavelina lepadiformis

Marine Drugs, 2022
The chemical investigation of the Mediterranean ascidian Clavelina lepadiformis has led to the isolation of a new lepadin, named lepadin L, and two known metabolites belonging to the same family, lepadins A and B.

Natural variation of model mutant phenotypes in Ciona intestinalis [PDF]

, 2008
The study of ascidians (Chordata, Tunicata) has made a considerable contribution to our understanding of the origin and evolution of basal chordates. To provide further information to support forward genetics in Ciona intestinalis, we used a combination ...

The relationship between Ascidians and plastic pollution: A systematic review of interaction mechanisms, biological impacts, and ecological roles [PDF]

BIO Web of Conferences
Microplastic (MP) and nanoplastic (NP) pollution are global threats that permeate marine ecosystems. As sessile filter-feeders, ascidians interact heavily with these pollutants.

Brain Sensory Organs of the Ascidian Ciona robusta: Structure, Function and Developmental Mechanisms

Frontiers in Cell and Developmental Biology, 2021
During evolution, new characters are designed by modifying pre-existing structures already present in ancient organisms. In this perspective, the Central Nervous System (CNS) of ascidian larva offers a good opportunity to analyze a complex phenomenon ...

Behavioural Responses to Ultrasound Antifouling Systems by Adult Solitary Ascidians

Journal of Marine Science and Engineering, 2023
Ultrasonic antifouling devices are installed globally on a variety of vessel types and are marketed as an environmentally friendly method for biofouling control. The aim of this study was to examine the effects of ultrasound on adults of three species of
