Article Synopsis
  • The study investigated the role of inflammation-related biomarkers (SII, SIRI, NLR, PLR) in predicting mid-term mortality and restenosis in patients with peripheral artery disease (PAD).
  • During an average follow-up of about 21 months, researchers found that higher levels of these biomarkers correlated with increased mortality rates, particularly highlighting NLR as a significant independent risk factor.
  • However, no significant links were established between these biomarkers and the occurrence of restenosis in the study participants.

Background: Parkinson's disease (PD) is the fastest-growing neurological disorder globally. Defining features include tremor, muscular rigidity, bradykinesia, and postural instability, which in combination with nonmotor symptoms such as cognitive impairment and orthostatic hypotension increase the risk of falls. Along with low bone mineral density, fracture risk is high in PD.

Three-dimensional (3D) cell assemblies, such as multicellular spheroids, can be powerful biological tools to closely mimic the complexity of cell-cell and cell-matrix interactions in a native-like microenvironment. However, potential applications of large spheroids are limited by the insufficient diffusion of oxygen and nutrients through the spheroids and, thus, result in the formation of a necrotic core. To overcome this drawback, we present a new strategy based on nanoparticle-coated microparticles.
