Knockdown of RRM1 in tumor cells promotes radio-/chemotherapy induced ferroptosis by regulating p53 ubiquitination and p21-GPX4 signaling axis

Cell Death Discovery, 2022
Ferroptosis, a type of regulated cell death brought about by lipid peroxidation, has been discovered to suppress tumor growth. Here, we report that targeting RRM1 promotes ferroptosis and affects sensitivity to radiation and chemotherapeutics in cancer ...

Magnetic nanoparticle sensing: decoupling the magnetization from the excitation field [PDF]

Journal of Physics D: Applied Physics, 2013
Remote sensing of magnetic nanoparticles has exciting applications for magnetic nanoparticle hyperthermia and molecular detection. We introduce, simulate, and experimentally demonstrate an innovation---a sensing coil that is geometrically decoupled from the excitation field---for magnetic nanoparticle spectroscopy that increases the flexibility and ...

Magnetic Field Sensing using Magnetic Fluids.

Journal of the Japan Society for Precision Engineering, 1993
Birefringence occurs when light passes through a magnetic fluid in a magnetic field. The phase difference caused by this phenomenon increases as the magnetic field is intensified. We have proposed an optical heterodyne method using Stabilized Transverse Zeeman Laser(STZL) for the detection of this phase difference caused by a magnetic field.
