Learning technology for detection and grading of cancer tissue using tumour ultrasound images1.

Background: Early diagnosis of breast cancer is crucial to perform effective therapy. Many medical imaging modalities including MRI, CT, and ultrasound are used to diagnose cancer.

Objective: This study aims to investigate feasibility of applying transfer learning techniques to train convoluted neural networks (CNNs) to automatically diagnose breast cancer via ultrasound images.

Euxanthone Attenuates Aβ-Induced Oxidative Stress and Apoptosis by Triggering Autophagy.

Alzheimer's disease (AD) is the most common neurodegenerative disorder and is characterized by the deposition of β-Amyloid (Aβ) plaques which contribute to its pathology. The present study was aimed at exploring the protective effects of euxanthone against Aβ-induced neurotoxicity both in vivo and in vitro. We found that euxanthone significantly attenuated Aβ-induced memory and spatial learning dysfunction and also significantly reversed Aβ-induced neuronal apoptosis and autophagy in the hippocampal region.
