Antioxidant PRDX3 gene therapy protects brain cells and prevents neurodegeneration in an animal model of Parkinson's disease.

Neurodegenerative diseases, including Parkinson's Disease (PD), are a significant global health challenge with no effective therapies to counteract neurodegeneration. Genetic and environmental factors lead to mitochondrial dysfunction and increased reactive oxygen species (ROS), resulting in oxidative stress. This stress reduces levels of Peroxiredoxin 3 (PRDX3), a key protein for maintaining ROS balance at the mitochondrial level, increasing the substantia nigra's susceptibility to damage.

Nanoencapsulation of extracts and isolated compounds of plant origin and their cytotoxic effects on breast and cervical cancer treatments: Advantages and new challenges.

This review analyzes the current progress in loaded nanoparticles (NPs) of plant extracts or isolated antineoplastic compounds used in breast and cervical cancer treatments. Also, it provides a comprehensive overview of the contributions made by traditional medicine and nanomedicine to the research of two of the most prevalent types of cancer in women worldwide: breast and cervical cancer. Searches were conducted in electronic databases to gather relevant information related to the biological activity of the NPs, which were meticulously reviewed.

Comparison of three techniques for decellularization of porcine bone-tendon-bone grafts.

Anterior cruciate ligament injuries are frequent afflictions related to sports or physical trauma. Autograft reconstruction strategies cause secondary injury to the patient. One alternative, supported by clinical evidence, is porcine xenografts.
