In Vivo Cytoskeletal AMPA Receptor Transport Imaging in C. elegans

open access: yesCytoskeleton, EarlyView.
ABSTRACT Long‐distance intracellular transport of ionotropic glutamate receptors (iGluRs) is essential for proper excitatory synaptic function underlying learning and memory. Many neuropsychiatric and neurodegenerative conditions have abnormal iGluR transport and trafficking, leading to an intense interest in the mechanisms and factors regulating these

Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Dual‐Functional Sulfonated Nanocellulose for Proton Exchange Membranes With High Proton Conductivity at Low Humidity

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A scalable dual‐functional strategy yields simultaneously sulfonated and nanosized cellulose for proton exchange membranes with continuous hydrogen‐bond networks. These sustainable membranes exhibit low‐humidity proton conductivity twofold higher than Nafion 212, providing a robust solution for next‐generation fuel cells.

Nanofiber PVA‐Based Membranes Incorporating Functionalized Spanish Broom Derivatives for Sustainable Water Purification

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study investigates Spanish broom (Spartium junceum) as a renewable source for electrospun composite membranes in sustainable water purification. MCC and biochar were functionalized with eco‐friendly precursors and nanomaterials (i.e., HNT, β‐CDs) to develop hybrid PVA nanofiber composites.

Protective effects of adiponectin receptor agonists against equine lamellar endoplasmic reticulum stress

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Lamellar endoplasmic reticulum (ER) stress occurs in hyperinsulinemia‐associated and sepsis‐related laminitis. Adiponectin is associated with reduced laminitis risk and inhibits ER stress in other species. Objectives To induce ER stress in ex vivo equine lamellar cells using pharmacological agents.
