Disks Surviving the Radiation Pressure of Radio Pulsars [PDF]

, 2004
The radiation pressure of a radio pulsar does not necessarily disrupt a surrounding disk. The position of the inner radius of a thin disk around a neutron star can be estimated by comparing the electromagnetic energy density generated by the neutron star

1800 MHz Radiofrequency Electromagnetic Field Impairs Neurite Outgrowth Through Inhibiting EPHA5 Signaling

Frontiers in Cell and Developmental Biology, 2021
The increasing intensity of environmental radiofrequency electromagnetic fields (RF-EMF) has increased public concern about its health effects. Of particular concern are the influences of RF-EMF exposure on the development of the brain. The mechanisms of

Fluoride exposure induces lysosomal dysfunction unveiled by an integrated transcriptomic and metabolomic study in bone marrow mesenchymal stem cells

Ecotoxicology and Environmental Safety, 2022
Fluoride has received much attention for its predominant bone toxicity in the human body. However, the toxic mechanism of bone injury caused by fluoride exposure remains largely unclear. Bone marrow mesenchymal stem cells (BMSCs) are widely used as model
