A model of chlorophyll a destruction by Calanus spp. and implications for the estimation of ingestion rates using the gut fluorescence method [PDF]

open access: yes, 1998
Chlorophyll a (chl a) destruction by groups of Calanus spp. with different long-term in situ feeding histories was compared. For copepods that had fed during both pre- and early-bloom conditions, degrees of chl a destruction were relatively constant at ...

Dual antidiabetic and antihypertensive activity of fucoxanthin isolated from Sargassum wightii Greville in in vivo rat model

open access: yesFood Science and Human Wellness, 2023
In a previous study from our laboratory, fucoxanthin purified from brown algae, Sargassum wightii Greville has found to exhibit antioxidant activity and inhibition of angiotensin-I-converting enzyme (ACE) in vitro. The present study aims in understanding

Integration of plastids with their hosts: Lessons learned from dinoflagellates. [PDF]

open access: yes, 2015
After their endosymbiotic acquisition, plastids become intimately connected with the biology of their host. For example, genes essential for plastid function may be relocated from the genomes of plastids to the host nucleus, and pathways may evolve ...

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

open access: yesApplied 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 ...

Enzymatic extraction of fucoxanthin from brown seaweeds [PDF]

open access: yesInternational Journal of Food Science & Technology, 2018
SummaryBrown seaweeds contain a number of bioactive compounds. The xanthophyll, fucoxanthin, has in vivo efficacy against disorders such as type 2 diabetes, obesity and cancer. Organic solvents are traditionally employed to extract fucoxanthin, but carry a toxic chemical and environmental burden.

Comparison between fluorometry and microscopy‐based phytoplankton assessments in the Laurentian Great Lakes

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Photosynthetic pigment fluorescence is commonly used in limnology and oceanography as a proxy for phytoplankton biomass. Fluorometry has been used to detect subsurface algal blooms, characterize dynamics of the deep chlorophyll layer, and to provide greater vertical resolution to phytoplankton monitoring.
