In a group of 30 digitalized children, we compared the digoxin levels in capillary and venous plasma samples, both of which were obtained simultaneously from each child. We statistically concluded that the venous plasma samples could surely be replaced by capillary plasma samples for measurements of plasma digoxin levels without any significant difference. Additionally, we showed that storing the capillary plasma samples at room temperature for 3 days did not lead to any significant change in digoxin levels. This is an important point for the hospitals and practitioners who do not have their own possibilities for digoxin determination.

Plants produce defensive toxins to deter herbivores. In response, some specialized herbivores evolved resistance and even the capacity to sequester toxins, affecting interactions at higher trophic levels. Here, we test the hypothesis that potential natural enemies of specialized herbivores are differentially affected by plant toxins depending on their level of adaptation to the plant-herbivore system.

The presence of circulating tumor cell (CTC) clusters is associated with disease progression and reduced survival in a variety of cancer types. In breast cancer, preclinical studies showed that inhibitors of the Na/K ATPase suppress CTC clusters and block metastasis. Here we conducted a prospective, open-label, proof-of-concept study in women with metastatic breast cancer, where the primary objective was to determine whether treatment with the Na/K ATPase inhibitor digoxin could reduce mean CTC cluster size.

Cardiac glycosides, known as inhibitors of Na,K-ATPase, have anti-cancer effects such as suppression of cancer cell proliferation and induction of cancer cell death. Here, we examined the signaling pathway elicited by cardiac glycosides in the human hepatocellular carcinoma HepG2 cells and human epidermoid carcinoma KB cells. Three kinds of cardiac glycosides (ouabain, oleandrin, and digoxin) inhibited the cancer cell proliferation and decreased the expression level of thyroid adenoma-associated protein (THADA).

Background: Atrial fibrillation (AF) is a prevalent cardiac arrhythmia, with ventricular rate control being a critical therapeutic target. However, the optimal range for ventricular rate control remains unclear. Additionally, the relationship between different levels of ventricular rate control and cardiac remodeling in patients with atrial fibrillation remains unclear.

- The study examines how chronic exposure to digoxin affects locomotor activity and brain chemistry in zebrafish.
- Zebrafish were housed in groups and exposed to 2 μM of digoxin for a week, resulting in increased hyperactivity and decreased anxiety in a novel environment test.
- The findings reveal significant changes in brain monoamine levels, indicating that cardiotonic steroids like digoxin can influence neurotransmission, which might have implications for neuropsychiatric conditions.
