Static and dynamic changes of intrinsic brain local connectivity in internet gaming disorder

BMC Psychiatry, 2023
Background Studies have revealed that intrinsic neural activity varies over time. However, the temporal variability of brain local connectivity in internet gaming disorder (IGD) remains unknown. The purpose of this study was to explore the alterations of

Temozolomide arrests glioma growth and normalizes intratumoral extracellular pH

Scientific Reports, 2017
Gliomas maintain an acidic extracellular pH (pHe), which promotes tumor growth and builds resistance to therapy. Given evidence that acidic pHe beyond the tumor core indicates infiltration, we hypothesized that imaging the intratumoral pHe in relation to
