BeatRatePy quantifies beat rate, contraction, and speed from label-free cardiac imaging data, showing consistent performance across different systems and datasets.

This study investigates the role of lysosomal Ca2+ signaling in heart rhythm and atrial function, finding that NAADP pathway inhibition affects SAN pacemaker activity and cAMP production in atrial myocytes.

This study identifies cardiac involvement in Niemann-Pick type C through ECG abnormalities, fibrosis, and transcriptomic changes in patients and Npc1-/- mice.

The paper identifies proteomic signatures of mitochondrial dysfunction in goats with atrial fibrillation, highlighting oxidative phosphorylation subunits and HSPA9 as a regulatory hub.

The paper uses IVIS Lysotracker imaging and RT-qPCR to assess lysosomal abundance and autophagy-related gene expression in young and aged mouse hearts, finding preserved acidic-vesicle pool and stable gene expression.

This study investigates the distribution and function of atrial granules in guinea pig and goat cardiomyocytes, finding they are acidic calcium stores closely associated with the sarcoplasmic reticulum and increase in number during atrial fibrillation.

This study shows that lysosomal calcium signaling via NAADP and calcium-stimulated adenylyl cyclase 1 and 8 contributes to the acute α-adrenergic response in atrial myocytes.

The paper uses proteomics and other methods to study endolysosomal changes in a goat model of atrial fibrillation, identifying upregulated pathways and specific proteins.

The paper presents a modified density gradient method for isolating endo-lysosomal proteins from cardiac tissue and reports proteomic analysis of these fractions in guinea pigs.
