Advanced Sensor Research, EarlyView.A deployable, chip‐integrated approach to the detection of heart attack biomarkers is demonstrated using silicon photonic microring resonators combined with microfluidics. By applying the Pound–Drever–Hall frequency locking technique, sensor signals are measured with improved signal‐to‐noise ratio, applying this to real‐time, selective readouts.

Aneurysm formation of pericardial patch in Manouguian procedure
Journal of the Saudi Heart Association, 2018 Pericardial patch has been used to repair cardiac defects; however, its strength as an aortoplasty patch to tolerate systemic pressure is a matter of debate. We report an aneurysmal dilatation of pericardial patch in aortoplasty.

Vitrification of Heart Valve Tissues
, 2014 Application of the original vitrification protocol used for pieces of heart valves to intact heart valves has evolved over time. Ice-free cryopreservation by Protocol 1 using VS55 is limited to small samples where relatively rapid cooling and warming rates are possible.

Advanced Sustainable Systems, EarlyView.This study explores microalgae cultivation for wastewater treatment and enhancement of poly lactic acid (PLA)‐based biocomposites. It achieves up to 99.9% nutrient removal, increases biomass productivity by 322%, and demonstrates a triphasic luxury phosphorus uptake system. Incorporation into PLA improves fire‐retardant properties, suggesting potential

Non‐Invasive Diagnosis of Chronic Myocardial Infarction via Composite In‐Silico‐Human Data Learning
Advanced Science, EarlyView.This study presents a non‐invasive machine learning model to identify infarct regions in the left ventricle using cardiac strain data. By combining rodent‐based simulated data with limited human data, the model achieves high accuracy in predicting infarct size and location without the need for gadolinium contrast agents, offering a promising ...
