This study deals with the effects of smoking on serum ceruloplasmin and its ferroxidase activity in pregnant women. The mean value (+/- SD) of serum ceruloplasmin in women smokers during pregnancy is significantly higher (p < 0.01) in comparison to that of nonsmokers, whereas the ferroxidase activity of ceruloplasmin in smokers is not significantly different from that of nonsmokers. These findings suggest that ceruloplasmin in women smokers loses part of its ferroxidase activity.

The pathophysiology of dystonia in Wilson disease (WD) is complex and poorly understood. Copper accumulation in the basal ganglia, disrupts dopaminergic pathways, contributing to dystonia's development via neurotransmitter imbalance. Despite advances in diagnosis and management, WD with dystonia remains a challenging condition to treat.

The striped stem borer (Chilo suppressalis, SSB) is a highly destructive insect pest in rice (Oryza sativa). SSB oral secretions (OSs) can induce plant defense responses in rice. However, the specific effectors in SSB OSs that mediate these interactions with rice remain poorly understood.

The objective of the present study was to determine whether the addition of a blend based on the essential oils of cinnamon, oregano, and eucalyptus to the liquid diets of calves would stimulate the immune system combined with anti-inflammatory action, minimize oxidative responses, and alter the intestinal microbiota, consequently enhancing animal growth. Twenty-four male Holstein calves (approximately five days old) were suckled for 60 days, underwent a weaning process, and were followed up until day 75 of the experiment. The calves were divided into control ( = 12) and phytobiotic ( = 12) groups, receiving commercial milk replacer and pelleted concentrate ad libitum.

Tinoco A-Team Deferasirox (Def), an orally administered iron-chelating drug, has drawn significant interest in repurposing for anticancer application due to the elevated Fe demand by cancer cells. But there are also concerns about its severe off target health effects. Herein Cu(II) binding is studied as a potential off target interaction.

Population-based biobanks enable genomic screening to support initiatives that prevent disease onset or slow its progression and to estimate the prevalence of genetic diseases in the population. Wilson's disease (WD) is a rare genetic copper-accumulation disorder for which timely intervention is crucial, as treatment is readily available. We studied WD in the Estonian Biobank population to advance patient screening, swift diagnosis, and subsequent treatment.
