Accuracy of Photoplethysmography-Derived Pulse Rate Variability Compared with Electrocardiography-Derived Heart Rate Variability: A Systematic Review and Meta-Analysis

Photoplethysmography-derived pulse rate variability (PPG-derived PRV) is increasingly used in wearable and camera-based biomedical sensors as a low-burden alternative to electrocardiography-derived heart rate variability (ECG-derived HRV), but its agreement with ECG-derived measu...

Streptomyces Extracellular Vesicles Promote Plant Defence Responses Through Direct Pathogen Inhibition and Immune Activation

Extracellular vesicles (EVs) play a critical role in mediating the transfer of bioactive nucleic acids and proteins between plants and pathogens. However, the involvement of EVs in interactions between plants and beneficial bacteria remains poorly understood. In this study, we is...
