Defect‐Induced Magnetism in Cerium‐Doped Barium Zirconate Perovskites: A Systematic Electron Paramagnetic Resonance Study of Oxygen Vacancies and Dopant Effects

Natural Sciences, Volume 6, Issue 2, April 2026.
Systematic investigation of the magnetic and structural properties of cerium‐doped barium zirconate (BaZr1−xCexO3, x = 0.005–0.04) perovskites synthesized by a microwave‐assisted hydrothermal route. This study uses Differential Scanning Calorimetry and Electron Paramagnetic Resonance as a function of temperature and sample composition.

Study of the synergistic effect of sodium citrate and phosphates on the colloidal stability of skim milk under controlled severe heat treatment conditions

International Journal of Dairy Technology, Volume 79, Issue 2, April–June 2026.
This study evaluates the combined effects of citrate and sodium mono‐, di‐ and triphosphates on the colloidal and thermal stability of skim milk, using physicochemical parameters. The results show that specific combinations of chelating salts increase milk resistance to heat‐induced coagulation, reduce the free calcium and maintain the micellar ...

Kisspeptin Restores Placental mTOR Signaling and Improves Glucose Homeostasis Mediators Disrupted by Maternal Hypothyroidism in Rats

Acta Physiologica, Volume 242, Issue 4, April 2026.
ABSTRACT Aim Reduced placental mTOR signaling is associated with intrauterine growth restriction and impaired maternal and placental metabolism. Since maternal hypothyroidism induces intrauterine growth restriction, and maternal treatment with kisspeptin‐10 (Kp10) has been shown to improve feto‐placental development in hypothyroid rats, this study ...

Layer‐Specific Astrocyte Morphological Responses in the CA3 Hippocampus Region During Piry Virus‐Induced Encephalitis

Hippocampus, Volume 36, Issue 2, March 2026.
ABSTRACT Astrocytes from distinct hippocampal layers exhibit region‐specific morphological traits, which may be influenced by their local microenvironment. During viral encephalitis, these cells undergo dynamic changes that can reflect layer‐specific vulnerability. In this study, we characterized whether astrocytes from different CA3 hippocampal layers
