The ζ toxin induces a set of protective responses and dormancy. [PDF]

PLoS ONE, 2012
The ζε module consists of a labile antitoxin protein, ε, which in dimer form (ε(2)) interferes with the action of the long-living monomeric ζ phosphotransferase toxin through protein complex formation.

Exploring the Frontiers of Food Science: A Comprehensive Review of Advanced Magnetic Resonance Applications in Food Analysis, Quality Analysis, and Safety Assessment

Food Science &Nutrition, Volume 13, Issue 7, July 2025.
The paper reviews advanced magnetic resonance (MR) technologies—NMR, MRI, ESR, and MRS—for food analysis, quality, and safety. MR techniques enable non‐invasive detection of adulteration, compositional profiling, and monitoring of food processing and storage.

ESBL-plasmids carrying toxin-antitoxin systems can be “cured” of wild-type Escherichia coli using a heat technique [PDF]

, 2013
Plasmid-encoded extended-spectrum beta-lactamase (ESBL)-enzymes are frequently produced by Escherichia coli. Several ESBL-plasmids contain genes for toxin- antitoxin (TA) systems, which assure the maintenance of plasmids in bacteria and prevent the ...

The Global Challenge of Antimicrobial Resistance: Mechanisms, Case Studies, and Mitigation Approaches

Health Science Reports, Volume 8, Issue 7, July 2025.
ABSTRACT Background and Aims Antimicrobial resistance (AMR) is projected to cause 10 million deaths annually by 2050 if left unaddressed, posing a severe threat to global health and modern medicine. This review analyzes the molecular and ecological mechanisms underlying antibiotic resistance and evaluates global efforts aimed at containment to identify

Therapeutic Effects of Naringin on Bisphenol A‐Induced Oxidative Stress Damage in Nervous and Reproductive Systems of Cockerel Chickens

Veterinary Medicine and Science, Volume 11, Issue 4, July 2025.
ABSTRACT Background Bisphenol A (BPA) is an endocrine‐disrupting chemical, and it is mostly used in plastic industries. Naringin is a potent flavonoid that has been reported to possess several beneficial pharmacological properties such as antioxidant, anti‐inflammatory, and antiapoptotic properties.

The bacterial Type III toxin-antitoxin system, ToxIN, is a dynamic protein-RNA complex with stability-dependent antiviral abortive infection activity. [PDF]

, 2018
Bacteria have evolved numerous defense systems to protect themselves from viral (bacteriophage) infection. The ToxIN system of Pectobacterium atrosepticum is a Type III toxin-antitoxin complex and "altruistic suicide" anti-phage system, which kills phage-

Cyanophage Infections in a Sponge Intracellular Cyanobacterial Symbiont

Environmental Microbiology, Volume 27, Issue 7, July 2025.
Intracellular cyanobacterial symbionts of sponges are shown to be susceptible to cyanophages, challenging assumptions about their isolation from viral exposure. The study reveals novel phage–host interactions and suggests conserved infection strategies across symbionts of marine and terrestrial animals.
