Oxidative Stress and Cataract Formation: Evaluating the Efficacy of Antioxidant Therapies.

This comprehensive review investigates the pivotal role of reactive oxygen species (ROS) in cataract formation and evaluates the potential of antioxidant therapies in mitigating this ocular condition. By elucidating the mechanisms of oxidative stress, the article examines how ROS contribute to the deterioration of lens proteins and lipids, leading to the characteristic aggregation, cross-linking, and light scattering observed in cataracts. The review provides a thorough assessment of various antioxidant strategies aimed at preventing and managing cataracts, such as dietary antioxidants (i.

Cortical bone plate properties assessment using inversion of axially transmitted low frequency ultrasonic guided waves.

Over the past few decades, early osteoporosis detection using ultrasonic bone quality evaluation has gained prominence. Specifically, various studies focused on axial transmission using ultrasonic guided waves and have highlighted this technique's sensitivity to intrinsic properties of long cortical bones. This work aims to demonstrate the potential of low-frequency ultrasonic guided waves to infer the properties of the bone inside which they are propagating.

Automatic flaw detection in sectoral scans using machine learning.

Phased array ultrasonic testing (PAUT) requires highly trained and qualified personnel to interpret and analyze images. It takes a solid understanding of wave propagation physics to comprehend the generated images. As such, the inspector's judgment and level of experience have a significant impact on the analysis's outcome.

Transcatheter Edge-to-Edge Repair for Acute Papillary Muscle Rupture After Transvenous Lead Extraction in a d-TGA.

We present a case of a patient known for dextrotransposition of the great arteries corrected with a Mustard procedure, in whom severe mitral valve regurgitation secondary to transvenous lead extraction was successfully repaired with transcatheter edge-to-edge repair using the TriClip device (Abbott Vascular).
