A quantitative study of the lac operon
The lac operon has been key in the study of genetic regulation. Consisting of three structural genes and a regulatory domain, the lac operon controls the manufacture of lactose-digesting enzymes in E. coli bacteria.

A run of consecutive fast‐translated codons (right) within the first 30 codons of lacZ (top) causes loss of the downstream transcript at positions coinciding with previously mapped intragenic Rho‐dependent termination sites (middle), and a corresponding loss of β‐galactosidase activity (bottom).

This study characterizes the bacteriome of Polygenis (Polygenis) bohlsi bohlsi fleas collected from free‐living Thrichomys fosteri in the Pantanal region of Brazil. The bacterial microbiota associated with male fleas exhibited greater phylogenetic diversity, and the overall community structure differed between the flea sexes.

Metagenomic Evaluation of Oral Microbiota in Patients Affected by Oral Lichen Planus: A Pilot Study
ABSTRACT Objective To characterize the oral bacterial and fungal microbiota of symptomatic oral lichen planus patients undergoing topical corticosteroid therapy and to explore microbial patterns potentially associated with subsequent oral candidiasis. Methods Twelve patients with clinically and histologically confirmed OLP were enrolled.

The ComEA/ComEC Operon is Critical for Nitrosative Stress Tolerance by an Oral Commensal
ABSTRACT Oral commensal streptococci play a large role in mediating microbial homeostasis. Our prior work has demonstrated that hydrogen peroxide (H2O2) produced by oral commensal streptococci can react with salivary nitrite (NO2) and generate peroxynitrite (ONOO−), a potent antimicrobial.

ABSTRACT Arginine metabolism in plants is targeted by phytopathogens such as Pseudomonas syringae strains, which produce toxins that affect enzymes of plant arginine metabolism, causing devastating infections in crops. In this work, the structural and functional properties of plant N‐acetylornithine glutamate acetyltransferase (NAOGAT), the key ...

Translating gut microbiome research into therapies for type 1 diabetes
Abstract Type 1 diabetes (T1D) is characterised by the loss of functional pancreatic β‐cells, for which lifelong insulin therapy remains the standard of care. Given that the gut microbiome can influence host health and that shifts in gut microbial profiles have been observed in T1D, growing interest has emerged in the role of the gut microbiome in T1D,

ABSTRACT Objectives Adequate traction is essential for safe and efficient colorectal endoscopic submucosal dissection (ESD), but gravitational traction is often insufficient in certain situations. Several traction techniques are reportedly effective.

ABSTRACT The interplay between diet, gut microbiota, and host immunity is central to food science. The Lachnospiraceae family ferments dietary fibers to produce short‐chain fatty acids (SCFAs), notably butyrate and propionate, with immunomodulatory potential. This critical review distinguishes established findings from hypotheses.
