Comparative Performance of Fluorometry and High Performance Liquid Chromatography in the Detection of Aflatoxin M1 in Two Commercial Cheeses [PDF]

, 2010
Aflatoxin M1 (AFM1) is frequently found in milk and dairy products. It is a metabolite formed in cows from aflatoxin B1 (AFB1), contained in animal feeds. In cheese production AFM1 distributes between curds and whey.

In situ Measurements of Phytoplankton Fluorescence Using Low Cost Electronics

Sensors, 2013
Chlorophyll a fluorometry has long been used as a method to study phytoplankton in the ocean. In situ fluorometry is used frequently in oceanography to provide depth-resolved estimates of phytoplankton biomass.

Revisiting the PCR‐Based Molecular Approaches for Mycotoxigenic Fusarium Species Detection and Quantification in Wheat

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 5, September 2026.
ABSTRACT Fusarium species cause yield losses in wheat production through fusarium head blight (FHB) and the associated contamination of regulated mycotoxins, such as trichothecenes and zearalenone. Despite the widespread use of PCR‐based molecular approaches for Fusarium detection, quantification, and chemotyping, most primers were developed prior to ...

Interannual Variations in Distribution and Density of Japanese Anchovy (Engraulis japonicus) Larvae in the Shelf‐Break Region of East China Sea During Spring (2001–2022)

Fisheries Oceanography, Volume 35, Issue 5, Page 777-794, September 2026.
ABSTRACT Japanese anchovy (Engraulis japonicus) is the most abundant fish in the East China Sea (ECS) and an important fishery resource throughout its life stages. Using samples collected along the ECS shelf‐break in April over a 22‐year period (2001–2022), we examined the horizontal distribution and interannual variability of larval density (mean ...

Changes in photosynthesis and grazing facilitate growth of a mixotrophic protist under ocean acidification and warming

New Phytologist, Volume 251, Issue 5, Page 2574-2587, September 2026.
Grazing rates of Ochromonas CCMP2951 expressed as carbon obtained per mean cell volume (a) and Caut/het‐photosynthetically fixed carbon divided by carbon obtained through grazing (b) in the four experimental treatments. Summary Mixotrophic protists capable of both photosynthesis and phagotrophy are key members of marine plankton communities.

Chlorophyll Fluorescence in Wheat Breeding for Heat and Drought Tolerance

Plants
The constantly growing need to increase the production of agricultural products in changing climatic conditions makes it necessary to accelerate the development of new cultivars that meet the modern demands of agronomists. Currently, the breeding process

Structural and functional characterisation of a reconstructed ancestral strigolactone receptor

The Plant Journal, Volume 127, Issue 5, September 2026.
Significance Statement Ancestral sequence reconstruction of the strigolactone receptor DWARF14 (D14) reveals that its substrate specificity and signalling mechanism have remained largely conserved in seed plants. Ancestral D14 exhibits improved recombinant yields, thermostability and catalytic activity relative to D14 from Arabidopsis thaliana ...

Essential mitochondrial activity in Physcomitrium patens relies on complementary cytochrome and alternative oxidase pathways

The Plant Journal, Volume 127, Issue 5, September 2026.
SUMMARY Mitochondrial respiration catalyses the transfer of electrons from NADH to oxygen through the activity of five multiprotein complexes. In plants, mitochondria also possess additional alternative electron transport pathways, including the alternative oxidase (AOX) pathway, which transfers electrons from ubiquinol to O2, bypassing the cytochrome ...

Preserved mitochondrial respiration in presence of oxidative stress and reduced mitochondrial mass after 10‐day bed rest in older adults

The Journal of Physiology, Volume 604, Issue 18, Page 7772-7798, 15 September 2026.
Abstract figure legend Ten older healthy male adults underwent 10 days of bed rest. Vastus lateralis muscle biopsies were collected at baseline (PRE) and after 10 days of bed rest (BR10), and mitochondrial adaptations were assessed using an integrative approach combining respirometry, protein analyses, RNA sequencing and transmission electron ...
