Dynamics of Compartment-Specific Proteomic Landscapes of Hepatotoxic and Cholestatic Models of Liver Fibrosis

Atomic force microscopy (AFM) stiffness mapping reveals changes in the local mechanics of liver tissue upon hepatotoxic injury

Liver fibrosis is characterized by excessive accumulation and remodeling of extracellular matrix (ECM) components, leading to altered tissue mechanics and progressive impairment of liver function.… Read More »Dynamics of Compartment-Specific Proteomic Landscapes of Hepatotoxic and Cholestatic Models of Liver Fibrosis

Accurate and rapid antibiotic susceptibility testing using a machine learning assisted nanomotion technology platform

Fig. 1 from Alexander Sturm et al. “Accurate and rapid antibiotic susceptibility testing using a machine learning-assisted nanomotion technology platform”: Nanomotion detection and recording platform. a Representation of the components of the nanomotion technology platform. b A representation of the nanomotion measurement setup with the (1) bacteria-loaded cantilever, (2) superluminescent light emitting diode (SLED) = light source, and (3) photodetector. c Schematic illustrating Gram-negative bacteria attached to the cantilever. Prior to attachment, bacteria are dispersed in gelling agarose while the cantilever surface is functionalized using positively charged poly-D-lysine. The gelling agent proved beneficial for an even distribution and stability of the bacterial attachment. d Representative standard 4-h nanomotion recordings with a 2-h medium phase (50% LB medium) followed by a 2-h drug phase with 32 µg/ml CRO for the E. coli reference strains ATCC-25922 (S, susceptible) and BAA-2452 (R, resistant). These recordings form the basis for using nanomotion to conduct AST. This study contains 219 recordings of ATCC-25922 and 225 recordings of BAA-2452 exposed to 32 µg/ml CRO with similar results. Data are available in the source data file. NANOSENSORSTM tipless uniqprobe AFM cantilevers SD-qp-CONT-TL from the NANOSENSORS Special Developments List were used.

Antimicrobial resistance (AMR) has become a significant threat to public health worldwide. * AMR diagnostic strategies such as antibiotic susceptibility testing (AST) help provide clinicians… Read More »Accurate and rapid antibiotic susceptibility testing using a machine learning assisted nanomotion technology platform
