Introduction: Direct repair of the pars defect in lumbar spondylolysis is an effective surgical procedure, but it is technically challenging. We assessed the feasibility of a new robotic system for intralaminar screw fixation of spondylolysis.
Patient Concerns: A 26-year-old man complained about frequent low back pain after failed conservative treatments.
Diagnosis: The lumbar computed tomography images demonstrated the presence of bilateral spondylolysis at the L5 level, with no spondylolisthesis.
Interventions: We performed one surgery of direct intralaminar screw fixation under the guidance of the TiRobot system. The trajectory of the screw was planned based on intraoperative 3-dimensional radiographic images. Then, the robotic arm spontaneously moved to guide the guide wires and screw insertion.
Outcomes: Bilateral L5 intralaminar screws were safely and accurately placed. No intraoperative complications occurred. Postoperative computed tomography showed good radiological results, without cortical perforation.
Conclusion: We report the first case of robot-assisted direct intralaminar screw fixation for spondylolysis using the TiRobot system. Robotic guidance for direct repair of spondylolysis could be feasible.

Cancer-related deaths primarily occur due to metastasis, a process involving the migration and invasion of cancer cells. In most solid tumors, metastasis occurs through collective cell migration (CCM), guided by "cellular leaders". These leader cells generate forces through actomyosin-mediated protrusion and contractility.

The apurinic/apyrimidinic site (AP site) is a highly mutagenic and cytotoxic DNA lesion. Normally, AP sites are removed from DNA by base excision repair (BER). Methoxyamine (MOX), a BER inhibitor currently under clinical trials as a tumor sensitizer, forms adducts with AP sites (AP-MOX) resistant to the key BER enzyme, AP endonuclease.

: Up to 27% of anterior cruciate ligament (ACL) reconstruction cases result in a residual positive pivot shift sign, indicating anteroposterior and rotational instability. This instability can compromise returning to sports and increase the risk of further injuries. The biomechanical role of the anterolateral ligament (ALL) in controlling internal knee rotation is well known.

The methylotrophic yeast belongs to the group of homothallic fungi that are able to spontaneously change their mating type by inversion of chromosomal DNA in the MAT locus region. As a result, natural and genetically engineered cultures of these yeasts typically contain a mixture of sexually dimorphic cells that are prone to self-diploidisation and spore formation accompanied by genetic rearrangements. These characteristics pose a significant challenge to the development of genetically stable producers for industrial use.

Propolis is a resinous substance produced by bees that has several biomedical properties that could contribute to the repair process of the gastric mucosa, such as antioxidant, anti-inflammatory, healing, and gastroprotective properties. Thus, this study aimed to determine the chemical composition of Mexicali propolis, its antioxidant capacity, and its effect on gastric repair. Three polarity-directed extracts were obtained: the ethanolic extract, the ethyl acetate extract, and the hexane extract.
