Maternal nutrition during pregnancy plays a pivotal role in influencing both maternal and fetal health, impacting neonatal anthropometric outcomes and long-term disease susceptibility. An advanced maternal age (AMA ≥ 35 years) has been linked to increased risks of obstetric complications and adverse neonatal outcomes, yet its specific nutritional p...

Binge drinking (BD) is the most common alcohol consumption model for adolescents, and has recently been related to the generation of high oxidation and insulin resistance (IR). White adipose tissue (WAT) is a target organ for insulin action that regulates whole‐body metabolism by secreting adipokines. The present study aimed to analyse the oxidativ...

High- and low- Se diets received by dams during gestation and lactation are related to insulin resistance in their pups. High-Se diet leads to an increase in serum insulin levels, which does not function properly, and an anabolic process. Low-Se diet is related to very low insulin values and an extreme catabolic energy imbalance. Selenoproteins hav...

Coenzyme Q10 (CoQ10) plays an essential role in cellular metabolism to produce ATP, which provides energy for muscle contraction and other vital cellular functions. Most of the ATP production occurs in the inner mitochondrial membrane, where coenzyme Q is found. Therefore, the main function attributed to CoQ is the transport of electrons in the mit...

Oxidative stress results from an imbalance between the formation and neutralization of reactive oxygen species (ROS), and it is imposed on cells because of one or more of the following factors: an increase in oxidant generation, a decrease in antioxidant protection, or a failure to repair oxidative damage. There is controversy about the susceptibil...

There is a growing body of evidence from animal research, epidemiologic, and clinical studies indicating an association between osteopenia and anemia. Iron (Fe) intake is directly correlated with mineral bone density, and iron deficiency diminishes the mineral bone content, the bone mass, and mechanical resistance. There is also an association of h...
