Molecular mechanism of mechanical pressure induced changes in the microenvironment of intervertebral disc degeneration.

Background: Lower back pain, as a typical clinical symptom of spinal degenerative diseases, is emerging as a major social problem. According to recent researches, the primary cause of this problem is intervertebral disc degeneration (IVDD). IVDD is closely associated with factors such as age, genetics, mechanical stimulation (MS), and inadequate nutrition.

A Survey on Artificial Intelligence Aided Internet-of-Things Technologies in Emerging Smart Libraries.

With the boom in artificial intelligence (AI) and Internet-of-Things (IoT), thousands of smart devices are interconnected with each other and deeply applied into human society. This prosperity has significantly improved public service and management, which were traditionally based on manual work. As a notable scenario, librarianship has embraced an era of "Smart Libraries" enabled by AI and IoT.

Copper-catalyzed activation of molecular oxygen for oxidative destruction of acetaminophen: The mechanism and superoxide-mediated cycling of copper species.

In this study, the commercial zero-valent copper (ZVC) was investigated to activate the molecular oxygen (O) for the degradation of acetaminophen (ACT). 50 mg/L ACT could be completely decomposed within 4 h in the ZVC/air system at initial pH 3.0.
