Beyond Immunity: Functional Outcomes of Dietary Yeast and Seaweed β‐Glucans in Adult Canine Nutrition

Journal of Animal Physiology and Animal Nutrition, Volume 110, Issue 5, Page 609-623, September 2026.
ABSTRACT β‐Glucans are functional compounds associated with health benefits; however, the physiological effects of different β‐glucan sources in dog foods remain incompletely understood. This study evaluated and compared the effects of β‐glucans derived from Euglena gracilis (seaweed) and Saccharomyces cerevisiae (yeast) on nutrient digestibility ...

NADP‐Dependent Isocitrate Dehydrogenase from Arabidopsis Roots Contributes in the Mechanism of Defence against the Nitro‐Oxidative Stress Induced by Salinity

The Scientific World Journal, Volume 2012, Issue 1, 2012., 2012
NADPH regeneration appears to be essential in the mechanism of plant defence against oxidative stress. Plants contain several NADPH‐generating dehydrogenases including isocitrate dehydrogenase (NADP‐ICDH), glucose‐6‐phosphate dehydrogenase (G6PDH), 6‐phosphogluconate dehydrogenase (6PGDH), and malic enzyme (ME).

Datos sobre los antioxidantes

EDIS, 2014
Nuestro cuerpo está constituido de células. Dentro de éstas ocurren constantemente reacciones químicas, que se conocen colectivamente como metabolismo. Estas reacciones son necesarias para la vida, pero algunas veces crean radicales libres. Los radicales libres son moléculas altamente reactivas que pueden iniciar reacciones dañinas en cadena en ...

UPLC‐QTOF‐MS/MS and Antifungal Activity of a Fraction Enriched in Saponins From Sarcomphalus joazeiro Against Candida spp

Biomedical Chromatography, Volume 40, Issue 7, July 2026.
ABSTRACT The development of antifungal resistance is a complex process that involves the interaction between hosts, drugs, and microbial factors, all of which contribute to therapeutic ineffectiveness. For this reason, studies on natural products as possible therapeutic alternatives are increasingly necessary in order to gain a better understanding of ...

Effects of Cadmium on Phenolic Composition and Antioxidant Activities of Erica andevalensis

Journal of Botany, Volume 2012, Issue 1, 2012., 2012
We evaluated the effects of cadmium on phenolic composition of Erica andevalensis, an endemic protected heather that grows in mine affected soils. Plants cultivated under laboratory‐controlled conditions were exposed to acute doses of cadmium to investigate the mechanisms this species possesses to survive in the presence of toxic metals in its natural ...
