Model of murine ventricular cardiac tissue for in vitro kinematic-dynamic studies of electromagnetic and beta2-adrenergic stimulation [PDF]

, 2017
In a model of murine ventricular cardiac tissue in vitro, we have studied the inotropic effects of electromagnetic stimulation (frequency, 75 Hz), isoproterenol administration (10 μM), and their combination.

Is There a Relationship Between Secondary Metabolites of Leaves and the Growth of Eucalyptus Species?

Physiologia Plantarum, Volume 178, Issue 3, May/June 2026.
ABSTRACT Flavonoids are essential molecules that affect plant growth and development and act as defense mechanisms against biotic and abiotic factors. This study aimed to assess whether the content of flavonoids in different species of Eucalyptus is related to tree growth.

A Case Report of Accidental Intoxication following Ingestion of Foxglove Confused with Borage: High Digoxinemia without Major Complications

Case Reports in Cardiology, 2019
Foxglove (Digitalis purpurea L.) leaves are frequently confused with borage (Borago officinalis L.), which is traditionally used as a food ingredient. Due to the presence of the cardiac glycosides, mostly digitoxin, foxglove leaves are poisonous to human

Alternative Approaches and Plant‐Based Remedies for Livestock Health Management Among the Batswana of Southern Africa: A Review

Chemistry &Biodiversity, Volume 23, Issue 4, April 2026.
ABSTRACT Due to limited access to, and the high cost of conventional veterinary services, Batswana communities often rely on ethnoveterinary practices for livestock health management. This review provides an in‐depth analysis on the ethnoveterinary uses, biological properties and safety assessment of plants utilised in livestock husbandry. A systematic

Zebrafish chemical screening reveals the impairment of dopaminergic neuronal survival by cardiac glycosides.

PLoS ONE, 2012
Parkinson's disease is a neurodegenerative disorder characterized by the prominent degeneration of dopaminergic (DA) neurons among other cell types. Here we report a first chemical screen of over 5,000 compounds in zebrafish, aimed at identifying small ...

Na+/K+-ATPase, cardiac glycosides, and tumor immunity

Frontiers in Chemistry
Tumor immunity arises from the coordinated action of innate and adaptive immune systems but is hindered by immune escape within the immunosuppressive tumor microenvironment (TME), for which ion channels and ion pumps have proved to be important.
