Summary: This study aimed to evaluate the durability of Sodium dimethyl dithiocarbamate (SDD)-stabilized air pollution control (APC) residues and determine the relationship between heavy metal leaching and environmental factors. The results showed that acidic and aerated conditions and temperatures above 40 degrees C accelerated SDD decomposition and reduced the durability of SDD-stabilized APC residues. The decline in durability was attributed to acid hydrolysis, thermal decomposition, and oxidative damage of SDD, leading to the breakage of the chelated sulfur-metal bond.

Summary: Alzheimer's disease is a major cause of senile dementia and is characterized by the aggregation of neurofibrillary tangles and amyloid plaques in the brain. The A beta 1-42 peptide is considered the primary cause of neurotoxicity due to its insolubility and subsequent aggregation. A beta 1-42 and A beta 1-40 have been identified as relevant biomarkers for AD diagnosis, and SurfaceAssisted Laser Desorption/Ionization Mass Spectrometry (SALDI-MS) was used to monitor the A beta 1-42/A beta 1-40 ratio without prior sample treatment.
