Discovering Cell-Targeting Ligands and Cell-Surface Receptors by Selection of DNA-Encoded Chemical Libraries against Cancer Cells without Predefined Targets.

Small molecules that can bind to specific cells have broad applications in cancer diagnosis and treatment. Screening large chemical libraries against live cells is an effective strategy for discovering cell-targeting ligands. The DNA-encoded chemical library (DEL or DECL) technology has emerged as a robust tool in drug discovery and has been successfully utilized in identifying ligands for biological targets.

"Beyond the Knife"-Applying Theranostic Technologies to Enhance Outcomes in Neurosurgical Oncology.

The current standard of care for brain tumor management includes maximal safe surgical resection followed by concurrent chemotherapy and radiation therapy. Recent advances in image-guided surgical techniques have enhanced the precision of tumor resections, yet there remains a critical need for innovative technologies to further improve patient outcomes. Techniques such as fluorescence image-guided neurosurgery in combination with stereotactic radiosurgery have improved outcomes for patients with brain tumors.

Long non-coding RNAs direct the SWI/SNF complex to cell type-specific enhancers.

The coordination of chromatin remodeling is essential for DNA accessibility and gene expression control. The highly conserved and ubiquitously expressed SWItch/Sucrose Non-Fermentable (SWI/SNF) chromatin remodeling complex plays a central role in cell type- and context-dependent gene expression. Despite the absence of a defined DNA recognition motif, SWI/SNF binds lineage specific enhancers genome-wide where it actively maintains open chromatin state.

Donation After Circulatory Determination of Death in Pediatric Patients on Extracorporeal Membrane Oxygenation at the Time of Death.

Background: Pediatric solid organ transplantation is challenging due to the limited availability of suitable organs resulting in an increasing waitlist. Many pediatric transplant recipients receive organs from deceased donors, often after neurologic determination of death. Organ donation from patients on extracorporeal membrane oxygenation (ECMO) at the time of death has been described in adults, offering the potential for donation after circulatory determination of death (DCDD) with minimal ischemia time.
