CLINICO–Demographic Profile and Outcomes of Hospitalised Children With Diphtheria in A Tertiary Care Hospital of Peshawar

Acta Paediatrica, EarlyView.
ABSTRACT Aim To determine the clinico‐demographic profile and predictors of mortality in hospitalised children with diphtheria. Methods This retrospective cohort study included 202 children aged 5–16 years diagnosed with diphtheria per WHO criteria at Lady Reading Hospital, Peshawar, from January 2023 to December 2024. Data on demographics, vaccination

A novel double-ribonuclease toxin-antitoxin system linked to the stress response and survival of Acidovorax citrulli

Microbiology Spectrum, 2023
Toxin-antitoxin (TA) systems are widespread among prokaryotes and can play an important role in the maintenance of genetic elements and pathogen virulence.

Force for ancient and recent life: viral and stem-loop RNA consortia promote life. [PDF]

, 2014
Lytic viruses were thought to kill the most numerous host (i.e., kill the winner). But persisting viruses/defectives can also protect against viruses, especially in a ubiquitous virosphere. In 1991, Yarmolinsky et al.

The 3D genome of Gigaspora margarita unveils stable chromatin and nucleolar organization and symbiont‐dependent genome dynamics

New Phytologist, EarlyView.
Summary Arbuscular mycorrhizal fungi (AMF) are widespread plant symbionts that enhance nutrient acquisition and influence ecosystem productivity. Previous chromosome‐level assemblies of the model species Rhizophagus irregularis revealed a two‐compartment genome architecture (active A and repressed B chromatin compartments), yet its conservation across ...

Type II Toxin-Antitoxin Systems and Persister Cells

mBio, 2018
Last year, Gerdes and colleagues published a paper (1) describing experiments that failed to support earlier work from their group (2, 3) which had implicated 10 type II toxin-antitoxin (TA) systems in the formation of antibiotic-tolerant Escherichia coli K-12 persister cells.

An SOS-Regulated Type 2 Toxin-Antitoxin System [PDF]

Journal of Bacteriology, 2009
ABSTRACTTheEscherichia colichromosome encodes seven demonstrated type 2 toxin-antitoxin (TA) systems: cassettes of two or three cotranscribed genes, one encoding a stable toxin protein that can cause cell stasis or death, another encoding a labile antitoxin protein, and sometimes a third regulatory protein.

Identification of a VapBC toxin–antitoxin system in a thermophilic bacterium Thermus thermophilus HB27 [PDF]

, 2017
There are 12 putative toxin–antitoxin (TA) loci in the Thermus thermophilus HB27 genome, including four VapBC and three HicBA families. Expression of these seven putative toxin genes in Escherichia coli demonstrated that one putative VapC toxin TTC0125 ...

Genome‐Wide In Silico Analysis of the Type VI Secretion System (T6SS) Within the Morganella Genus

MicrobiologyOpen, Volume 15, Issue 3, June 2026.
▪ Species‐specific T6SS patterns among Morganella genus (M. morganii and M. sibonii). ▪ Only one‐third of M. morganii isolates haboured a T6SS. ▪ All M. sibonii possess four T6SS clusters. ▪ M. sibonii exhibited a wide diversity of effectors compared to M. morganii.

Combining cysteine scanning with chemical labeling to map protein-protein interactions and infer bound structure in an intrinsically disordered region

Frontiers in Molecular Biosciences, 2022
The Mycobacterium tuberculosis genome harbours nine toxin-antitoxin (TA) systems of the mazEF family. These consist of two proteins, a toxin and an antitoxin, encoded in an operon.

Protein design and RNA design: Perspectives

Quantitative Biology, Volume 14, Issue 2, June 2026.
Abstract Advances in deep learning and generative modeling have transformed the landscape of protein and RNA design, enabling rapid and precise creation of novel biomolecules with tailored structures and functions. In protein design, generative deep learning frameworks now support backbone generation, sequence optimization, and joint sequence–structure
