Article Synopsis
  • - Urbanization significantly impacts global environmental change and can influence evolutionary processes in species by causing habitat fragmentation and small population sizes, as seen in the eastern grey squirrel (Sciurus carolinensis).
  • - Genetic analysis of 403 eastern grey squirrels revealed moderate genetic diversity and low inbreeding, showing higher migration and genetic connectivity in urbanized areas compared to more fragmented agricultural landscapes.
  • - The study suggests that while urban areas can disrupt gene flow, eastern grey squirrels have maintained connectivity across these regions, particularly where tree cover is present, indicating that landscape composition plays a critical role in wildlife adaptation to urbanization.

Background: The services of Healthcare and Social Assistance (HCSA) workers are needed by society around the clock. As a result, these workers are exposed to shift work and long work hours. The combination of demanding work schedules and other hazards in the HCSA work environment increases the health and safety risks to these workers, as well as to their patients/clients and the public.

Introduction: MRI gradient-fields may induce extrinsic voltage between electrodes and conductive neurostimulator enclosure of implanted deep brain stimulation (DBS) systems, and may cause unintended stimulation and/or malfunction. Electromagnetic (EM) simulations using detailed anatomical human models, therapy implant trajectories, and gradient coil models can be used to calculate clinically relevant induced voltage levels. Incorporating additional anatomical human models into the EM simulation library can help to achieve more clinically relevant and accurate induced voltage levels, however, adding new anatomical human models and developing implant trajectories is time-consuming, expensive and not always feasible.
