Phosphate Transporters Mediate the Uptake of Monothioarsenate

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Arsenic (As) is one of the most problematic environmental toxins. Exposure to As, predominantly via drinking water and the intake of food, represents a major human health threat. Various species of As exist in the environment, among them organic and inorganic thioarsenates.

Effect of Lime, Humic Acid and Moisture Regime on the Availability of Zinc in Alfisol

open access: yesThe Scientific World Journal, 2007
Lime and humic acid application can play an important role in the availability of zinc in paddy soils. We conducted laboratory incubation experiments on a rice growing soil (Alfisol) to determine the effect of lime, humic acid and different moisture ...

Nitrite supplementation alleviates cerebrovascular dysfunction in chronically stressed mice, but cognitive decline remains

open access: yesExperimental Physiology, EarlyView.
Abstract This study aimed to determine whether sodium nitrite supplementation prevented chronic stress‐induced cerebrovascular dysfunction and cognitive decline. We hypothesize that nitrite supplementation will prevent the oxidative environment and cerebrovascular dysfunction associated with chronic stress and maintain cognitive health.

Mitochondrial physiology in cardiac muscle of deer mice native to high altitude

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend High‐altitude deer mice exhibited evolved changes in mitochondrial energy metabolism and reactive oxygen species (ROS) management that may support cardiac performance under cold hypoxic conditions. High‐altitude mice had increased activity of lactate dehydrogenase (LDH) in the heart, probably enhancing the capacity for lactate ...

Multiparametric MRI to Predict Response to Irreversible Electroporation Plus Anti‐PD‐1 Immunotherapy in Pancreatic Ductal Adenocarcinoma

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 4, Page 2266-2276, April 2026.
ABSTRACT Purpose To investigate contrast‐enhanced T1‐weighted MRI and diffusion‐weighted magnetic resonance imaging (DWI) for early prediction of tumor response to combined irreversible electroporation (IRE) and anti‐PD‐1 immunotherapy. Methods Murine pancreatic ductal adenocarcinoma (PDAC) cells KRAS* were inoculated into the pancreas of C57BL/6 mice.
