Basic Science and Pathogenesis.

Background: Alzheimer's disease (AD) is a progressive neurodegenerative disease characterized by neuronal dysfunction leading to decreased memory and cognitive function. AD research has largely focused on the potential pathogenic role of two disease hallmarks: amyloid beta and phosphorylated tau. However, pharmacological interventions targeting these disease hallmarks have met with limited clinical trial success.

Urinary Catheterization Management in Older Adults with Hip Fracture: A Systematic Review.

Objectives: Urinary catheterization is a common procedure in the perioperative management of patients with hip fracture. However, decisions on its insertion or removal are often variable. This systematic review aimed to synthesize current evidence on urinary catheterization management in older patients with hip fracture by thoroughly reviewing the implementation of structured programs.

Frailty and Behavioral and Psychological Symptoms of Dementia: A Single Center Study.

During the time-course of cognitive decline, Behavioral and Psychological Symptoms of Dementia (BPSD) may arise, negatively impacting the outcomes. The aim of this single center, longitudinal study was to evaluate the correlation between frailty and BPSD in a population of older patients with dementia. BPSD were classified into three clusters: "mood/apathy" (depression, apathy, sleep disturbances, appetite disturbances), "psychosis" (delusions, hallucinations, and anxiety), and "hyperactivity" (agitation, elation, motor aberrant behavior, irritability, disinhibition).

Enhanced Remediation of Phenanthrene and Naphthalene by Corn-Bacterial Consortium in Contaminated Soil.

The persistent and hazardous nature of polycyclic aromatic hydrocarbons (PAHs) released into the soil has become a critical global concern, contributing to environmental pollution. In this study, the removal efficiency of phenanthrene and naphthalene degradation by complex flora or pure bacteria combined with corn and their effects on the growth of corn, pH, and the number of soil bacteria were investigated using a pot experiment. The results indicate that the corn remediation method (P) outperformed degrading bacteria remediation (B) for phenanthrene, yet the combination (PB) exhibited significantly higher removal efficiency.
