Advances in implants and biological therapies have significantly improved trauma care, offering surgeons a variety of solutions for complex cases. This study evaluates the outcomes of three patients with complex Schatzker type V tibial plateau fractures, treated with open reduction and internal fixation supplemented by tricalcium phosphate bone void filler. The surgical approach was selected based on the specific fracture pattern.

Article Synopsis
  • The study investigates how reallocating time among physical activity, sedentary behavior, and sleep affects obesity indicators like BMI and waist circumference across various age groups.
  • Researchers analyzed data from 9,818 participants using isotemporal substitution models to understand the implications of these behavior changes.
  • Results indicated that even small shifts of 10-30 minutes can significantly impact obesity, with reallocating moderate-to-vigorous physical activity (MVPA) to lighter activities or sedentary behavior having particularly detrimental effects.

InAs semiconductor quantum dots (QDs) emitting in the near-infrared are promising platforms for on-demand single-photon sources and spin-photon interfaces. However, the realization of quantum-photonic nanodevices emitting in the telecom windows with similar performance remains an open challenge. In particular, nanophotonic devices incorporating quantum light emitting diodes in the telecom C-band based on GaAs substrates are still lacking due to the relaxation of the lattice constant along the InGaAs graded layer which makes the implementation of electrically contacted devices challenging.

Neurosteroids have a crucial role in physiological intrinsic regulations of the Central Nervous System functions. They are derived from peripheral steroidogenic sources and from the de novo neurosteroidogenic capacity of brain cells. Significant alterations of neurosteroid levels have been frequently observed in neuroinflammation and neurodegenerative diseases.
