Functional outcome of cell seeded tracheal scaffold after mechanical stress in vitro.

Tracheal tissue engineering is still facing major challenges: realization of efficient vascularization and mechanical properties comparable to native trachea need to be achieved. In this study, we present a strategy for the manufacturing of a construct for tracheal tissue engineering by conditioning through cell seeding followed by mechanical stimulation in vitro. Scaffolds derived from porcine trachea decellularized with supercritical carbon dioxide were seeded with stem cells of different tissue sources and cultured in a bioreactor for 21 days under mechanical stimulation.

Efficacy and safety of pembrolizumab in patients with advanced urothelial carcinoma deemed potentially ineligible for platinum-containing chemotherapy: Post hoc analysis of KEYNOTE-052 and LEAP-011.

Background: First-line pembrolizumab monotherapy is a standard of care for platinum-ineligible patients with advanced urothelial carcinoma (UC). No global standardized definition of platinum ineligibility exists. This study aimed to evaluate the efficacy and safety of pembrolizumab monotherapy in patients with UC who met various criteria for platinum ineligibility.

OQuPy: A Python package to efficiently simulate non-Markovian open quantum systems with process tensors.

Non-Markovian dynamics arising from the strong coupling of a system to a structured environment is essential in many applications of quantum mechanics and emerging technologies. Deriving an accurate description of general quantum dynamics including memory effects is, however, a demanding task, prohibitive to standard analytical or direct numerical approaches. We present a major release of our open source software package, OQuPy (Open Quantum System in Python), which provides several recently developed numerical methods that address this challenging task.

Recording provenance of workflow runs with RO-Crate.

Recording the provenance of scientific computation results is key to the support of traceability, reproducibility and quality assessment of data products. Several data models have been explored to address this need, providing representations of workflow plans and their executions as well as means of packaging the resulting information for archiving and sharing. However, existing approaches tend to lack interoperable adoption across workflow management systems.

Impact of Prior Chemotherapy on Response to Second-line Pembrolizumab in Urothelial Cancer: Exploratory Analysis of the Phase 3 KEYNOTE-045 Trial.

Background And Objective: Until recently, the standard first-line treatment for advanced urothelial carcinoma (UC) was platinum-based combination chemotherapy followed by avelumab maintenance therapy for patients without progressive disease (PD). For patients with advanced UC who experience PD or recurrence, standard-of-care treatment is pembrolizumab monotherapy based on the phase 3 KEYNOTE-045 study. This post hoc analysis of the KEYNOTE-045 study evaluated the efficacy of pembrolizumab compared with chemotherapy by the best response to prior platinum-based chemotherapy.
