Derivation of the multiply-branched ergot alkaloid pathway of fungi. [PDF]
Microb Biotechnol, 2023 Ergot alkaloids are a large family of fungal specialized metabolites that are important as toxins in agriculture and as the foundation of powerful pharmaceuticals. Fungi from several lineages and diverse ecological niches produce ergot alkaloids from at least one of several branches of the ergot alkaloid pathway.

"Spasms in Silence": A case of coronary vasospasm-induced ventricular fibrillation. [PDF]
J ArrhythmA 56‐year‐old man presented following an aborted cardiac arrest. His initial ECGs showed episodes of transient repolarization abnormalities. Coronary vasospasm can be a precipitant for ventricular arrhythmia in these patients, underpinning the importance of continuous ECG for accurate diagnosis and management.
