Microbiome of Apical Intracanal and Extraradicular Biofilms From the Same Roots of Teeth With Persistent Apical Periodontitis: An Observational Study

International Endodontic Journal, Volume 59, Issue 5, Page 806-818, May 2026.
ABSTRACT Aim Bacterial biofilms around the apex are crucial in disease progression and persistence of apical periodontitis. While intracanal biofilms initiate infection, extraradicular biofilms contribute to treatment resistance and persistence. Thus, a comprehensive understanding of these biofilms may help elucidate mechanisms underlying persistent ...

Comprehensive comparative-genomic analysis of Type 2 toxin-antitoxin systems and related mobile stress response systems in prokaryotes

Biology Direct, 2009
Background The prokaryotic toxin-antitoxin systems (TAS, also referred to as TA loci) are widespread, mobile two-gene modules that can be viewed as selfish genetic elements because they evolved mechanisms to become addictive for replicons and cells in ...

Hepatitis B Virus, Pneumococcal, Diphtheria, and Tetanus Vaccination Responses in Compensated Cirrhosis

Liver International, Volume 46, Issue 5, May 2026.
ABSTRACT Background and Aims Cirrhosis favours infections that can lead to liver decompensation and death. Some of these infections can be prevented by vaccination. This study aimed to evaluate the immune response after HBV, pneumococcal, diphtheria, and tetanus vaccination in cirrhotic patients.

Redefining Therapies for Drug‐Resistant Tuberculosis: Synergistic Effects of Antimicrobial Peptides, Nanotechnology, and Computational Design

Advanced Healthcare Materials, Volume 15, Issue 14, 10 April 2026.
Antimicrobial peptide (AMP)‐loaded nanocarriers provide a multifunctional strategy to combat drug‐resistant Mycobacterium tuberculosis. By enhancing intracellular delivery, bypassing efflux pumps, and disrupting bacterial membranes, this platform restores phagolysosome fusion and macrophage function.
