Identification of Antimycobacterial Natural Products from a Library of Marine Invertebrate Extracts. [PDF]

open access: yesMedicines (Basel), 2022
Tuberculosis (TB) remains a public health crisis, requiring the urgent identification of new anti-mycobacterial drugs. We screened several organic and aqueous marine invertebrate extracts for their in vitro inhibitory activity against the causative ...

A phylogenomic framework and timescale for comparative studies of tunicates [PDF]

open access: yesBMC Biology, 2018
Background Tunicates are the closest relatives of vertebrates and are widely used as models to study the evolutionary developmental biology of chordates. Their phylogeny, however, remains poorly understood, and to date, only the 18S rRNA nuclear gene and

An updated 18S rRNA phylogeny of tunicates based on mixture and secondary structure models [PDF]

open access: yesBMC Evolutionary Biology, 2009
Background Tunicates have been recently revealed to be the closest living relatives of vertebrates. Yet, with more than 2500 described species, details of their evolutionary history are still obscure. From a molecular point of view, tunicate phylogenetic

Identification and population genetic comparison of three ascidian species based on mtDNA sequences. [PDF]

open access: yesEcol Evol, 2020
Three ascidians—Ciona robusta, Ciona savignyi, and Styela clava were identified from the northeast region of China using morphological characteristics and mitochondrial cytochrome c oxidase subunit I (cox1) as genetic marker. C. savignyi has particularly high level of haplotype diversity and nucleotide diversity varied moderately. Ciona spp. had a weak

Marine Fouling Characteristics of Biocomposites in a Coral Reef Ecosystem

open access: yesAdvanced Sustainable Systems, Volume 5, Issue 9, September 2021., 2021
Two biodegradable biocomposites based on starch–polydimethylsiloxane and soybean lecithin‐wax‐polyurethane are fabricated and evaluated as scaffolds for the growth of oceanic organisms. Such materials placed underwater on the Maldivian lagoon for six months show biodegradation and the growth of several organisms, including coral larvae.
