High-Resolution Free-Breathing Chemical-Shift-Encoded MRI for Characterizing Lymph Nodes in the Upper Abdomen.

Objectives: Accurate lymph node (LN) staging is crucial for managing upper abdominal cancers. Ultrasmall superparamagnetic iron oxide (USPIO)-enhanced magnetic resonance imaging effectively distinguishes healthy and metastatic LNs through fat/water and -weighted imaging. However, respiratory motion artifacts complicate detection of abdominal LNs.

Heterobimetallic contacts in statistical co-crystals of homoleptic coordination compounds with ligand-encoded H⋯F bonds: structure, photophysics and mechano-responsive properties.

In this work, the structural and photophysical characterization of statistical co-crystals based on two homoleptic Pt(II) and Pd(II) complexes as well as their mechano-responsive properties are reported. Ligand-dominated H⋯F bonds, which reinforce metal-metal interactions in the crystalline state, support emission from MMLCT states. All co-crystals show a distinct red-shift upon grinding, showcasing their inherent mechano-responsive characteristics stemming from (hetero-)bimetallic contacts.

Measuring individual colony MICs is a more sensitive method to detect the effect of antimicrobials on antimicrobial susceptibility than the proportion of colonies resistant.

Unlabelled: The ResistAZM randomized controlled trial found that the receipt of ceftriaxone/azithromycin, compared to ceftriaxone was not associated with an increase in the proportion of oral commensal Neisseria spp. and streptococci with azithromycin resistance 14 days after treatment. We repeated the analyses by measuring the minimum inhibitory concentrations (MICs) of azithromycin and ceftriaxone for individual colonies of commensal Neisseria spp.

Ciprofloxacin Concentrations in Food Could Select for Quinolone Resistance in : An In Vivo Study in .

: The use of antimicrobials to treat food animals leaves antimicrobial residues in foodstuffs. The World Health Organization (WHO) defines the acceptable daily intakes (ADIs) of these residues as the dose of these antimicrobials that is safe for an average human to consume on a daily basis. We hypothesized that the lowest dose of ciprofloxacin classified as safe by the WHO could select for ciprofloxacin-resistant strains of in a model.

Scalable Bulk Synthesis of Phase-Pure γ-SnN as a Model for an Argon-Flow-Mediated Metathesis Reaction.

Nitrides represent a promising class of materials for a variety of applications. However, bulk synthesis remains a challenging task due to the stability of the N molecule. In this study, we introduce a simple and scalable approach for synthesizing nitride bulk materials.
