Article Synopsis
- The study investigates the potential of bovine pulmonary visceral pleura (PVP) as a durable material for bioprosthetic heart valve cusps, addressing the need for improved long-term outcomes in heart valve replacements.
- PVP was prepared, shaped, and tested in lab conditions (100 million cycles), and then implanted in pigs to assess its performance in a biological environment.
- Results indicated that PVP bioprosthetic valves maintained structural integrity, showed no signs of calcification or thrombotic deposits, and demonstrated promising mechanical strength and biocompatibility for use in heart valve replacements.
An innovative approach for the rapid identification of wood species is presented. By combining X-ray fluorescence spectrometry with convolutional neural network machine learning, 48 different wood specimens were clearly differentiated and identified with a 99% accuracy. Wood species identification is imperative to assess illegally logged and transported lumber.
