Synergistic and Antagonistic Effects of Chemical Pollutants and Parasitic Fungi on Cyanobacterial Metabolism

Environmental Toxicology, EarlyView.
ABSTRACT Freshwater ecosystems are increasingly impacted by anthropogenic pollutants, including the widely used herbicide metolachlor (MET) and cigarette butt (CB) litter. Parasites represent an additional biotic stressor that can modulate pollutant effects on their hosts.

First Insights on Photoreceptor Organ Ultrastructure in Marine Chaetonotida (Gastrotricha): Species of Xenotrichula and Draculiciteria (Xenotrichulidae)

Acta Zoologica, EarlyView.
ABSTRACT Marine gastrotrichs inhabit sediments with limited available light, yet evidence suggests that photoreceptor organs are present throughout the phylum Gastrotricha. Here, we confirm this proposition with ultrastructural descriptions of photoreceptive organs in two species of Xenotrichulidae (Order Chaetonotida) that lack pigmented ocelli ...

Born-Oppenheimer Expansion for Diatomic Molecules with Large Angular Momentum [PDF]

, 2007
Semiclassical and Born-Oppenheimer approximations are used to provide uniform error bounds for the energies of diatomic molecules for bounded vibrational quantum number n and large angular momentum quantum number l.

Human IDO2 exhibits unique binding affinities distinct to those of human IDO1

The FEBS Journal, EarlyView.
Although indoleamine 2,3‐dioxygenase 2 (IDO2) is highly homologous to IDO1, it displays markedly lower catalytic activity. We found that IDO2 binds L‐tryptophan (L‐Trp) in a flipped orientation stabilized by the IDO2‐specific residue His143. Replacement of His143 with the IDO1‐equivalent tyrosine restored an IDO1‐like binding mode and increased ...

Recent advances of emergent extraction technologies to enhance bioactive compounds extraction of microalgae—An overview towards application in cosmetics

International Journal of Cosmetic Science, EarlyView.
Microalgae extracts show immense potential in cosmetics for their bioactivities; emerging extraction techniques enhance bioactive compound yield from microalgae. Abstract Microalgae have attracted significant interest in numerous sectors, particularly in the cosmetic industries, owing to their rich composition of bioactive compounds. This paper aims to

Auxin response and PIN‐mediated transport in chlorophyte algae

Journal of Integrative Plant Biology, EarlyView.
Like multicellular plants, green algae respond to auxin and move it across their cells. However, their PIN‐like proteins do not act like plant auxin exporters, suggesting that basic auxin transport evolved early and specialized directional transport appeared later in plant evolution.

Chloroplast and mitochondrial genomes of Sphaerosorus coelastroides Pascher (Xanthophyceae) from Central Appalachia, Clinch River, Virginia, United States

Journal of Phycology, EarlyView.
Abstract This report describes the isolation and culture of Sphaerosorus coelastroides from the plankton of a freshwater river in the central Appalachian mountain chain. This alga was first observed in a dry freshwater riverbed in Central Europe in 1908 and, since then, has been included in Xanthophyceae surveys from nearly all continents with ...

Holdfast adhesion in the kelp Alaria marginata: Cell wall polysaccharides and phenolics

Journal of Phycology, EarlyView.
Abstract Adhesion is a critical process in the survival of seaweeds, especially in wave‐swept environments. Kelp (Laminariales) sporophytes secrete adhesives from specialized rhizoid cells to anchor themselves to the substrate and withstand immense forces applied by waves.

Lyapunov instability of rigid diatomic molecules via diatomic potential molecular dynamics [PDF]

, 1998
We develop a molecular dynamic method to evaluate the full Lyapunov spectrum for two-dimensonal fluids composed of rigid diatomic molecules. The Lyapunov spectra are obtained for 18 rigid diatomic molecules for various bond lengths d(10(-3)less than or ...
