Propagation of pathologic α-synuclein from kidney to brain may contribute to Parkinson's disease.

The pathogenesis of Lewy body diseases (LBDs), including Parkinson's disease (PD), involves α-synuclein (α-Syn) aggregation that originates in peripheral organs and spreads to the brain. PD incidence is increased in individuals with chronic renal failure, but the underlying mechanisms remain unknown. Here we observed α-Syn deposits in the kidneys of patients with LBDs and in the kidney and central nervous system of individuals with end-stage renal disease without documented LBDs.

MVGNN-PPIS: A novel multi-view graph neural network for protein-protein interaction sites prediction based on Alphafold3-predicted structures and transfer learning.

Protein-protein interactions (PPI) are crucial for understanding numerous biological processes and pathogenic mechanisms. Identifying interaction sites is essential for biomedical research and targeted drug development. Compared to experimental methods, accurate computational approaches for protein-protein interaction sites (PPIS) prediction can save significant time and costs.

Associations of insulin resistance estimated by glucose disposal rate with frailty progression.

Objectives: To investigate the relationship between estimated glucose disposal rates (eGDR) and the progression of frailty, using longitudinal data.

Methods: We analyzed four waves of data from the China Health and Retirement Longitudinal Study (CHARLS) from 2011 to 2018, involving 6,778 middle-aged and older adults. eGDR was calculated using a specific formula, categorizing participants into high and low eGDR groups based on the lowest quartile (8.

Association of Circulating Phenylacetylglutamine With Multi-Vessel Coronary Disease Severity and Outcomes in ST-Segment-Elevation Myocardial Infarction.

Background: There is a lack of evidence regarding the association between plasma phenylacetylglutamine levels and lesion severity and clinical prognosis in patients with ST-segment elevation myocardial infarction (STEMI) with multivessel coronary disease (MVCD). This study aims to investigate the potential of phenylacetylglutamine as a biomarker for major adverse cardiovascular events (MACEs) of patients with STEMI and MVCD.

Methods And Results: Clinical data and blood samples were collected from 631 patients with STEMI and MVCD, who underwent primary percutaneous coronary intervention.

[Analysis of clinical features and prognostic factors of focal cerebral arteriopathy in children].

To summarize the clinical characteristics of focal cerebral arteriopathy (FCA) in children, and to analyze its influencing factor of prognosis. A retrospective cohort study was conducted. Clinical data from 40 children with FCA who were hospitalized at the Department of Neurology, Beijing Children's Hospital, Capital Medical University, from September 2015 to August 2024 were collected.
