Pheochromocytoma and heart rate variability: a systematic review and meta-analysis

International Journal of Cardiology. Cardiovascular Risk and Prevention
Introduction: Pheochromocytoma is a catecholamine-producing tumor, that may alter cardiovascular activity. Conveniently, sympathovagal activity can be measured non-intrusively and pain-free through heart rate variability (HRV).

Pheochromocytoma: Yes or No? [PDF]

Clinical Chemistry, 2014
A 76-year-old woman was admitted for cardiac decompensation, hypertension, and renal failure. To explore her chronic hypertension, urinary fractionated metanephrines were quantified. Fig. 1A shows the chromatogram of the patient's urine, and Fig. 1B shows the chromatogram of a calibration standard. A very large methoxytyramine …

Cordycepin mediates neuroprotection against apoptosis via ERK/CREB signaling activation in Aβ1–42‐induced neuronal cell models

Ibrain, Volume 11, Issue 1, Page 84-97, Spring 2025.
This study demonstrates cordycepin's neuroprotective effects against Aβ1–42‐induced apoptosis in neuronal cells, mediated through the activation of the extracellular signal‐regulated kinase/cyclic AMP‐responsive element‐binding protein (ERK/CREB) signaling pathway.
