Survivors of childhood cancer face reduced fertility, which can be a significant cause for concern. Our study aimed to assess the prevalence of fertility-related concerns and identify associated factors. Self-report data were collected with the Long-Term Survivor Questionnaire at the Alberta Children's Hospital's Long-Term Survivor Clinic (LTSC) between January 2021 and September 2023.

Evaluation of relevant seed traits is an essential part of most plant breeding and biotechnology programmes. There is a need for non-destructive, three-dimensional assessment of the morphometry, composition, and internal features of seeds. Here, we introduce a novel tool, MRI-Seed-Wizard, which integrates deep learning algorithms with non-invasive magnetic resonance imaging (MRI) for use in a new domain-plant MRI.

Article Synopsis
  • The use of titanium cable cerclage for additional support in plate osteosynthesis of distal femoral fractures shows promise in improving fracture stability and load-bearing capacity compared to traditional steel wire cerclage.
  • A study involved creating unstable fractures in nonosteoporotic cadaver femora and testing the strength of their fixations, revealing that titanium cerclage specimens withstood higher failure loads than those without it.
  • However, both methods faced failure primarily due to distal screw issues, and no significant differences were noted in stiffness or deformity between the two fixation methods.

In lithium-ion batteries, the solid electrolyte interphase (SEI) passivates the anode against reductive decomposition of the electrolyte but allows for electron transfer reactions between anode and redox shuttle molecules, which are added to the electrolyte as an internal overcharge protection. In order to elucidate the origin of these poorly understood passivation properties of the SEI with regard to different molecules, we used a four-electrode-based generator-collector setup to distinguish between electrolyte reduction current and the redox molecule (ferrocenium ion Fc) reduction current at an SEI-covered glassy carbon electrode. The experiments were carried out in situ during potentiostatic SEI formation close to battery operation potentials.
