Determination of Extra Virgin Olive Oil Adulteration Using Laser Induced Fluorometry – Chlorophyll Relative Intensity Method

Acta Technologica Agriculturae
A new method has been proposed for detecting the potential adulteration of extra virgin olive oil with processed sunflower oil. This method is based on analysing the laser-induced fluorescence (LIF) spectra of samples.

A Pan‐Methylome Framework for Population‐Scale Bacterial Epigenomics

Advanced Science, EarlyView.
A scalable quantitative framework unlocks population‐level comparative epigenomics in bacteria. By transforming site‐level data into standardized traits, this approach reconstructs methylation‐informed phylogenies and defines the core epigenome.

SDPR–STK38 axis controls the proliferation–differentiation balance in alveolar type II cells

Animal Models and Experimental Medicine, EarlyView.
The present study identifies SDPR as a pivotal regulator orchestrating the balance between proliferation and differentiation in alveolar type II (AT2) cells. In SDPR+/+ cells, SDPR binds to and inhibits STK38 activity, thereby sustaining GSK‐3β signaling functionality to promote cyclin D1 degradation and maintain cell cycle homeostasis.

Estimating the Concentration of DNA by Fluorometry Using Hoechst 33258 [PDF]

, 2017
Measuring the concentration of DNA using fluorometry is more sensitive than spectrophotometry, allowing the detection of nanogram quantities of DNA. In this assay, DNA preparations of known and unknown concentrations are incubated with the fluorochrome ...

Integrated phytochemical and bioactivity profiling of Xanthium strumarium fruits from Korea and China: Implications for origin‐specific quality specification

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Geographic origin influences the phytochemical composition and biological activities of medicinal plant resources. Xanthium strumarium L. (XS) fruit is widely used in East Asian traditional medicine. However, current pharmacopeial standards primarily recognize Chinese‐derived material, despite the availability and traditional use of
