Blue-fluorescence of NADPH as an indicator of marine primary production

open access: yes, 2004
Nicotinamide Adenine Dinucleotide Phosphate (NADPH) is the primary product of photosynthesisand can therefore serve as an indicator of biomass and photosynthetic activity.

Natural Anthraquinone‐Like Compound Extracted from Green Husk of Walnut Improves Photocatalytic H2O2 Production Catalyzed by TiO2 Nanoparticles

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In this work, a novel biomolecule/semiconductor hybrid catalyst was prepared by loading anthraquinone‐liked juglone onto anatase TiO2. This catalyst exhibited high photocatalytic activity for H2O2 production. Hydrogen peroxide (H2O2) is a vital oxidant with broad industrial applications, and its production via photocatalysis represents a highly ...

Potential of Seaweed to Improve the Quality and Shelf Life of Fish and Fishery Products

open access: yesFood Safety and Health, EarlyView.
Growing global demand for safe fish preservation has increased interest in natural alternatives. Seaweed‐derived bioactive compounds possess antioxidant and antimicrobial properties that enhance fish quality, safety, and shelf life. These sustainable preservatives may reduce spoilage and synthetic preservative use, though further research ...

Development of an Automated Low-Cost Multispectral Imaging System to Quantify Canopy Size and Pigmentation

open access: yesSensors
Canopy imaging offers a non-destructive, efficient way to objectively measure canopy size, detect stress symptoms, and assess pigment concentrations. While it is faster and easier than traditional destructive methods, manual image analysis, including ...

Mitochondria‐targeted nanomedicine for cancer therapy: Targeting strategies, therapeutic mechanisms, and translational challenges

open access: yesInterdisciplinary Medicine, EarlyView.
This review highlights recent advances in mitochondria‐targeted nanomedicine for cancer therapy. It summarizes key targeting strategies and delineates four principal therapeutic mechanisms: oxidative stress–induced mitochondrial dysfunction, disruption of energy metabolism, direct mitochondrial damage, and induction of immunogenic cell death.

Nitrogen‐doped graphene quantum dots tune the mineral, acid, and sugar profile of raisins in a cultivar‐specific manner

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Carbon dots are emerging as low‐toxicity nano‐biostimulants, but their effects on the integrated mineral, organic‐acid, and sugar profiles of grape berries remain poorly characterized, especially in indigenous Vitis vinifera L. cultivars.

Sodium sulfite can reliably induce chemical hypoxia without toxic effects in the model sea anemone species, Exaiptasia diaphana

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Climate change is accelerating the deoxygenation of aquatic ecosystems, so understanding its effects on biological processes is increasingly critical. An emerging method for inducing hypoxia during experimentation utilizes sodium sulfite (SSI) to scavenge oxygen; however, it remains unclear if hypoxia‐inducing concentrations of SSI are toxic ...

Picosecond fluorescence of intact and dissolved PSI-LHCI crystals [PDF]

open access: yes, 2008
Over the last years many crystal structures of photosynthetic pigment-protein complexes have been determined, and used extensively to model spectroscopic results obtained on the same proteins in solution. However, the crystal structure is not necessarily

Leaf heat tolerance in a native Californian shrub responds in expected and unexpected ways to differences in range, season, and sunlight exposure

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Earth's ecosystems are experiencing wide‐ranging impacts from global climate change, including increased average and extreme temperatures. These temperature shifts can drastically affect plant physiology, threatening the future of even common plant species. Here, we focus on photosynthetic function in a native Southern California shrub species.
