Background: Numerous studies have demonstrated that patients with Parkinson's disease (PD) have a higher prevalence of substantia nigra (SN) hyperechogenicity compared with controls. Our aim was to explore the neuroimaging characteristics of transcranial sonography (TCS) of patients with PD and those with PD with dementia (PDD). The correlation between the echogenicity of the SN and clinical symptoms in Chinese patients with PDD was also assessed.

- The study analyzed the geochemical susceptivity of groundwater in a karst system, focusing on the correlation of major ions.
- Key findings showed that HCO3- and Ca2+ were the most significant ions affecting groundwater quality, with a ranking in geochemical susceptivity.
- The research classified groundwater zones into low, moderate, and high susceptivity categories based on the HCO3- index, identifying high-susceptivity zones as areas at risk for pollution due to interactions with surface water.
