Deep Volumetric Super‐Resolution Imaging in Thick Biological Specimens With Sparse Scanning SIM

open access: yesAdvanced Science, EarlyView.
Sparse scanning structured illumination microscopy (SS‐SIM) extends the axial depth in super‐resolution fluorescence imaging by combining rapid laser scanning, pixel‐addressed intensity modulation, and sCMOS camera detection. SS‐SIM yields 1.6× lateral and 1.7× axial resolution gains over wide‐field microscopy and enables imaging through 300–600 µm ...

Guidelines for the Anti‐Obesity Assays of Food Bioactives in Caenorhabditis elegans

open access: yesAgriFood: Journal of Agricultural Products for Food, EarlyView.
This Guideline uses Caenorhabditis elegans as a model organism to systematically explain and summarize the research strategies and experimental methods for the anti‐obesity effects of food bioactives. ABSTRACT The obesity has become a global public health problem and is closely related to a variety of chronic diseases.

Grape Seed Polyphenols Enhance Antioxidant Activity and Prolong the Lifespan of Caenorhabditis elegans Through SKN‐1/Nrf2 Pathway

open access: yesAgriFood: Journal of Agricultural Products for Food, EarlyView.
GSP extends C. elegans lifespan, enhances stress resistance and reproduction, boosts antioxidant defenses (↑SOD/CAT/GSH‐Px, ↓ROS), remodels glycolysis/TCA/one‐carbon metabolism dose‐dependently, and activates SKN‐1/Nrf2 and H3K4 methylation—linking redox control to epigenetic modulation.

Characterizing the causes and consequences of calcium oxalate crystal presence in Vitis riparia

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Calcium oxalate biomineralization in plants is phylogenetically widespread and morphologically diverse, but the function of these inorganic crystals is an area of active debate. The variety of environmental conditions that produce the crystals, as well as the inconsistent evidence that they provide antiherbivore defense across plant ...
