Initial Stage of Oxidation on Si(111)-7×7 Surface Investigated by Scanning Tunneling Microscope
The initial oxidation of Si(111)-7×7 surface has been investigated by taking the STM images of samples dosed with oxygen at room temperature and high temperatures between 500 °C and 750 °C. In particular, diff...

Open AccessImmunotherapy targeting plasma ASM is protective in a mouse model of Alzheimer’s disease
Acid sphingomyelinase (ASM) has been implicated in neurodegenerative disease pathology, including Alzheimer’s disease (AD). However, the specific role of plasma ASM in promoting these pathologies is poorly und...
