In recent years, a number of studies have proved that OGM, as a new generation of cytogenomic technique, has higher resolution and stronger ability to discover genomic variants compared with conventional genetic techniques. This article has systematically reviewed the principles, characteristics, advantages and limitations of OGM technology, and its applications in the diagnosis of genetic disorders.

Microplastics/nanoplastics and neurological health: An overview of neurological defects and mechanisms.

The widespread use of plastic products worldwide has brought about serious environmental issues. In natural environments, it's difficult for plastic products to degrade completely, and so they exist in the form of micro/nanoplastics (M/NPs), which have become a new type of pollutant. Prolonged exposure to M/NPs can lead to a series of health problems in humans, particularly toxicity to the nervous system, with consequences including neurodevelopmental abnormalities, neuronal death, neurological inflammation, and neurodegenerative diseases.

A review focuses on a neglected and controversial component of SCI: myelin debris.

Myelin sheath, as the multilayer dense structure enclosing axons in humans and other higher organisms, may rupture due to various injury factors after spinal cord injury, thus producing myelin debris. The myelin debris contains a variety of myelin-associated inhibitors (MAIs) and lipid, all inhibiting the repair after spinal cord injury. Through summary and analysis, the present authors found that the inhibition of myelin debris can be mainly divided into two categories: firstly, the direct inhibition mediated by MAIs; secondly, the indirect inhibition mediated by lipid such as cholesterol.
