SYNGR4 and PLEKHB1 deregulation in motor neurons of amyotrophic lateral sclerosis models: potential contributions to pathobiology

Amyotrophic lateral sclerosis is the most common adult-onset neurodegenerative disease affecting motor neurons.Its defining feature is progressive loss of motor neuron function in the cortex, brainstem, and spinal cord, leading to paralysis and death.Despite major advances in identifying genes that can cause disease when mutated and model the disea

Mechanistic insights into coke suppression and enhanced olefin selectivity in mixed metal oxide-modified SAPO-34 for high-performance methanol-to-olefins catalysis

The methanol-to-olefins (MTO) process is a key catalytic route for light olefin production, yet challenges related to catalyst deactivation and coke formation persist.In this study, we investigate the catalytic performance of SAPO-34 (SP) and a modified SAPO-34 catalyst incorporating a mixed metal oxide of indium oxide and cerium oxide (SPM) to enh
