Klebsiella pneumoniae is a Gram-negative, rod-shaped bacterium of medical significance. It typically exists as part of the normal flora of the human intestine but can cause severe infections in the healthcare setting due to its rapid acquisition of antibiotic resistance. Cultivating and extracting genomic DNA from this bacterium is crucial for downstream characterization and comparative analyses. To provide a standardized approach for growing K. pneumoniae in the laboratory setting, this collection of protocols provides step-by-step procedures for routine culturing, generating growth curves, storing bacteria, and extracting genomic DNA. © 2024 The Authors. Current Protocols published by Wiley Periodicals LLC. Basic Protocol 1: Reviving K. pneumoniae from frozen stocks Basic Protocol 2: Cultivating K. pneumoniae in rich growth medium Alternate Protocol: Cultivating in minimal liquid growth medium Basic Protocol 3: Enumerating K. pneumoniae colony forming units Basic Protocol 4: Growth curves Basic Protocol 5: Genomic DNA extraction Basic Protocol 6: Characterizing K. pneumoniae strains based on genomic sequence Basic Protocol 7: Storage of K. pneumoniae frozen stocks in glycerol Basic Protocol 8: Storage of K. pneumoniae in agar stabs.

Background: In implant-based breast surgery, microbial contamination of implant surfaces predisposes complications such as overt periprosthetic infection and has been linked to capsular contracture (CC). Anti-microbial practices, including povidone-iodine (PVP-I) breast pocket irrigation, are routinely employed to minimise these risks. No standardised protocol for using this antiseptic exists, particularly concerning the ideal concentration.

Rationale And Objectives: To establish an advanced automated bone marrow (BM) segmentation model on whole-body (WB-)MRI in monoclonal plasma cell disorders (MPCD), and to demonstrate its robust performance on multicenter datasets with severe myeloma-related pathologies.
Materials And Methods: The study cohort comprised multi-vendor, multi-protocol imaging data acquired with varying field strength across 8 different centers. In total, 210 WB-MRIs of 207 MPCD patients were included.

Background: Accelerated continuous theta burst stimulation (acTBS) is a more intensive and rapid protocol than continuous theta burst stimulation (cTBS). However, it remains uncertain whether acTBS exhibits anxiolytic effects. The aim of this study was to investigate the impact of acTBS on anxiety model mice and elucidate the underlying mechanisms involved, in order to provide a more comprehensive understanding of its effects.

Natural products (NPs) continue to serve as an invaluable source in drug discovery, and peripheral evolution of NPs is a highly efficient evolution strategy. Herein, we describe a unified "methyl to amide" peripheral evolution of Tanshinone IIA and Cryptotanshinone for discovery of NLRP3 inflammasome inhibitors. There were 54 compounds designed and prepared, while the chemoinformatic analysis revealed that these evolved NP analogues occupy a unique chemical space.

Background: The effects of ionizing radiation (IR) involve a highly orchestrated series of events in cells, including DNA damage and repair, cell death, and changes in the level of proliferation associated with the stage of the cell cycle. A large number of existing studies in literature have examined the activity of genes and their regulators in mammalian cells in response to high doses of ionizing radiation. Although there are many studies, the research in effect of low doses of ionizing radiation remains limited.
