Laboratory of Phytopathology, Wageningen University, Wageningen, The Netherlands.
Article Synopsis
- Saponins are toxic compounds found in plants that help defend against pests and pathogens, with known mechanisms for fungal resistance focused on enzyme secretion.
- Researchers investigated how the fungus Botrytis cinerea tolerates specific saponins from tomato and Digitalis purpurea, discovering four mechanisms that help it overcome the toxicity.
- One novel mechanism involves enzymatic deglycosylation, while the others function in the fungal membrane, suggesting implications for understanding tolerance in both plant pathogenic fungi and potential human pathogens.

Comparative Therapeutic Potential of Cardioactive Glycosides in Doxorubicin Model of Heart Failure.
Cardiovasc Toxicol
January 2022
Escola de Veterinária da Universidade Federal de Minas Gerais, Belo Horizonte, Brazil.
Article Synopsis
- The study explored the effects of cardioactive glycosides oleandrin, ouabain, and digoxin on heart damage caused by doxorubicin in adult rats.
- Rats were divided into four groups, injected with doxorubicin, and then treated with glycosides or saline for seven days, with various health evaluations conducted afterward.
- Results showed that while oleandrin and digoxin reduced some heart remodeling effects from doxorubicin, none of the glycosides demonstrated effective treatment for congestive heart failure in this model.
A Case of Digoxin Toxicity Due to Acute Renal Failure.
Cureus
August 2021
Internal Medicine, University of Alabama, Tuscaloosa, USA.
Article Synopsis
- Since the 1997 Digitalis Investigation Group trial, the use of digoxin has decreased as doctors prefer other medications like ACE inhibitors, ARBs, and beta-blockers, which are more effective in reducing health risks.
- Despite this decline in usage and better monitoring, digoxin toxicity continues to be a serious issue, leading to significant health complications.
- In cases of suspected digoxin toxicity, supportive care is crucial, including stopping the medication and possibly using digoxin-specific antibody fragments, especially in patients with conditions like acute renal failure, emphasizing the need for doctors to remain vigilant about this risk.

Bidirectional Ventricular Tachycardia in a Young Female: A Case of Andersen-Tawil Syndrome.
Mil Med
January 2023
Department of Cardiology, William Beaumont Army Medical Center, El Paso, TX 79920, USA.
Article Synopsis
- - Bidirectional ventricular tachycardia (VT) is a rare heart rhythm disorder linked to conditions like digitalis toxicity and Andersen-Tawil syndrome (ATS), which is caused by mutations in the KCNJ2 gene.
- - A young female patient with a family history of heart issues was diagnosed with ATS after showing symptoms like palpitations and physical features such as mandibular hypoplasia; she was treated successfully with a beta-blocker, leading to reduced ectopy.
- - There are no established treatment guidelines for ventricular dysrhythmias in ATS patients, but this case suggests that beta-blockers can improve symptoms, and patients may not need exercise restrictions as her ectopy burden decreased during activity.
