Bacterial cell surface characterization by phage display coupled to high-throughput sequencing.

The remarkable capacity of bacteria to adapt in response to selective pressures drives antimicrobial resistance. Pseudomonas aeruginosa illustrates this point, establishing chronic infections during which it evolves to survive antimicrobials and evade host defenses. Many adaptive changes occur on the P.

Nivolumab + Ipilimumab as Immunotherapeutic Boost in Metastatic Urothelial Carcinoma: A Nonrandomized Clinical Trial.

Importance: Studies with nivolumab, an approved therapy for metastatic urothelial carcinoma (mUC) after platinum-based chemotherapy, demonstrate improved outcomes with added high-dose ipilimumab.

Objective: To assess efficacy and safety of a tailored approach using nivolumab + ipilimumab as an immunotherapeutic boost for mUC.

Design, Setting, And Participants: In this phase 2 nonrandomized trial, patients with mUC composed 2 cohorts.

Physiological oxygen measurements Schrödinger's cat in 3D cell biology.

After the development of 3D cell culture methods in the middle of the last century and the plethora of data generated with this culture configuration up to date, it could be shown that a three-dimensional arrangement of cells in most of the cases leads to a more physiological behavior of the generated tissue. However, a major determinant for an organotypic function, namely, the dissolved oxygen concentration in the used -system, has been neglected in most of the studies. This is due to the fact that the oxygen measurement in the beginning was simply not feasible and, if so, disturbed the measurement and/or the -system itself.
