Metabolic Responses to Polymyxin Treatment in Acinetobacter baumannii ATCC 19606: Integrating Transcriptomics and Metabolomics with Genome-Scale Metabolic Modeling

mSystems, 2019
Multidrug-resistant (MDR) Acinetobacter baumannii has emerged as a very problematic pathogen over the past decades, with a high incidence in nosocomial infections. Discovered in the late 1940s but abandoned in the 1970s, polymyxins (i.e., polymyxin B and

Immunometabolic Modulation by Low‐Dose Sodium Butyrate: PI3K/Akt/mTOR Signalling Orchestrates Macrophage Polarization to Protect Against Clostridioides difficile Colitis

Immunology, EarlyView.
Clostridioides difficile toxins TcdA and TcdB enter intestinal epithelial cells (IECs) via specific receptors, disrupt tight‐junction integrity and activate PI3K/Akt/mTOR signalling, promoting inflammasome assembly and IL‐1β release. Toxin‐induced IEC apoptosis further weakens the epithelial barrier.

Polymyxins: review with emphasis on nephrotoxicity [PDF]

, 2009
As polimixinas são antibióticos polipeptídeos com potente ação sobre várias bactérias gram-negativas. O seu uso foi praticamente abandonado entre 1970 e 1980, em virtude do aparecimento de drogas com menor toxicidade.

Design and Evaluation of Novel Polymyxin Fluorescent Probes

Sensors, 2017
Polymyxins (polymyxin B and colistin) are cyclic lipopeptide antibiotics that serve as a last-line defence against Gram-negative “superbugs”. In the present study, two novel fluorescent polymyxin probes were designed through regio-selective modifications

Patterns of Drug Resistance, Drug Resistance Conferring Mutations and Genomic DNA Methylation Revealed in Mycobacterium tuberculosis From South Africa

Tropical Medicine &International Health, EarlyView.
ABSTRACT Tuberculosis remains a major public health threat globally, with drug‐resistant strains undermining treatment efficacy. We analyzed 126 Mycobacterium tuberculosis (M. tuberculosis) isolates with diverse drug resistance spectra and selected 35 for whole genome sequencing (WGS) using Illumina NextSeq, SMRT PacBio Onso and SMRT PacBio Revio ...

Systemic pirfenidone treatment fails to mitigate fibrosis and compromises functional recovery in a porcine model of volumetric muscle loss

Experimental Physiology, EarlyView.
Abstract Repurposing clinically approved antifibrotic agents presents a potential near‐term therapeutic strategy to mitigate the extensive fibrotic scarring that follows severe volumetric muscle loss (VML) injury and inhibits functional recovery. We hypothesized that daily oral administration of pirfenidone, an FDA‐approved antifibrotic, would mitigate
