Validation of Fucoxanthin from Microalgae Phaeodactylum tricornutum for the Detection of Amyloid Burden in Transgenic Mouse Models of Alzheimer’s Disease

Applied Sciences, 2021
The visualization of misfolded Aβ peptides by using fluorescence chemical dyes is very important in Alzheimer’s disease (AD) diagnosis. Here, we describe the fluorescent substance, fucoxanthin, which detects Aβ aggregates in the brain of AD transgenic ...

Crystal structure of fucoxanthin: resolving a long‐standing crystallographic challenge

Acta Crystallographica Section C, EarlyView.
The first small‐molecule single‐crystal X‐ray structure of fucoxanthin is reported, resolving a long‐standing crystallographic problem in carotenoid structural chemistry.Fucoxanthin (C42H58O6) is a highly functionalized allenic epoxy xanthophyll containing hydroxy, acetoxy, ketone and conjugated polyene units.

Linking variation in genome size to cyst size in chrysophytes

Journal of Phycology, EarlyView.
Abstract Genome size varies tremendously across eukaryotes, which often contain far more DNA than expected from their biological complexity. To explain this paradox, selection‐based hypotheses propose that genome size evolves through selection acting on life‐history traits correlated with the phenotypic effects, independent of its genic content.

Carotenoid‐Rich Pigment Extract From Micrococcus terreus SK34 Induces Apoptosis in SH‐SY5Y Neuroblastoma Cells: Integrated Metabolomic, Molecular Docking, and Experimental Validation

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
Carotenoid extract from Micrococcus terreus SK34 was characterized by LC‐Q‐TOF‐MS and evaluated for its in vitro anticancer potential. The extract exhibited selective cytotoxicity against different cancer cell lines, particularly neuroblastoma cells (SH‐SY5Y), while sparing normal cells.

The Mycorrhizal Fungal Species Funneliformis mosseae Reshapes Rhizosphere Microbial Metabolic Pathways of Soybeans Under Tetracycline Stress

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
The presence of residual antibiotics (tetracycline) poses a threat to food safety in the black soils of northeastern China and a mycorrhizal fungal species Funneliformis mosseae could mitigate the negative effects. This study tracked the changes in soybeans' rhizospheric microbial profiles and the associated metabolites during the bioremediation ...

Open Ocean Biogeochemical Impacts of Extreme Terrestrial Precipitation

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Extreme events reshape ocean ecosystems with significant implications for nutrient and carbon cycling. Here, we demonstrate that flooding on land can be a significant driver of biogeochemical variability in the open ocean, even in relatively dry climates.
