The surge of antimicrobial resistance threatens efficacy of current antibiotics, particularly against Pseudomonas aeruginosa, a highly resistant gram-negative pathogen. The asymmetric outer membrane (OM) of P. aeruginosa combined with its array of efflux pumps provide a barrier to xenobiotic accumulation, thus making antibiotic discovery challenging.

The aims of this study were to evaluate the outcomes for young adult patients undergoing intracapsular hip fracture fixation and to assess factors associated with failure and patient-reported outcome measures (PROMs).
Methods: From 2008 to 2018, 112 consecutive patients ≤60 years of age (mean age, 48 years [range, 20 to 60 years]; 54% male) were retrospectively identified as having undergone fixation of an intracapsular hip fracture.
We report the use of streaming data interfaces to perform fully online data processing for serial crystallography experiments, without storing intermediate data on disk. The system produces Bragg reflection intensity measurements suitable for scaling and merging, with a latency of less than 1 s per frame. Our system uses the CrystFEL software in combination with the ASAP::O data framework.

Synchrotron X-ray diffraction, thermal analysis, and Raman and absorption spectroscopy revealed three high-temperature polymorphs that appear when BZS is heated in air prior to complete oxidation (BaZrS + 5O → BaSO + ZrO + 2SO↑) at 700 °C with the approximate stability ranges: BaZrS IV (62)T < 400 °CBaZrS III (63)400 °C ≤ T ≤ 500 °CBaZrS II14/ (140)500 °C ≤ T ≤ 700 °CDifferential scanning calorimetry (DSC) revealed exothermic features accompanying the IV → III and III → II phase changes. Furthermore, the direct band gap varied inversely with temperature with distinct energies for each polymorph (1.
