Purpose: In this feasibility study, we aimed to create a dedicated pulmonary augmented reality (AR) workflow to enable a semi-automated intraoperative overlay of the pulmonary anatomy during video-assisted thoracoscopic surgery (VATS) or robot-assisted thoracoscopic surgery (RATS).
Methods: Initially, the stereoscopic cameras were calibrated to obtain the intrinsic camera parameters. Intraoperatively, stereoscopic images were recorded and a 3D point cloud was generated from these images.
Article Synopsis
- HTLV-1 is linked to serious health issues like Adult T-cell Leukemia/Lymphoma and HAM/TSP; thus, screening potential organ donors for the virus is vital due to high transmission risks, particularly in kidney transplant recipients.
- A study at the Iranian Tissue Bank from 2014 to 2021 found that 3% of 3,814 potential organ/tissue donors tested positive for HTLV-1, with rates significantly dropping from 6% to 0.5% over the years.
- Females showed a higher positivity rate (4%) than males (2%), and donors with brain death had a much lower infection rate (0.2%) compared to those with circulatory death (4%).
Bone tissue engineering is a promising approach to overcome the limitations of traditional autograft bone transplantation. Graphene quantum dots (GQDs) have been suggested as an enhancement for osteogenic differentiation. This study aimed to investigate the ability of the fibrin hydrogel scaffold in the presence of graphene quantum dots to promote osteogenic differentiation of human Wharton's jelly-derived mesenchymal stem cells (hWJ-MSCs).
