Discovery of a Dual‐Target DNAzyme for Clostridioides difficile and Listeria monocytogenes Diagnostics

open access: yesChemistryEurope, Volume 4, Issue 3, March 2026.
A newly discovered fluorogenic DNAzyme, RFD‐CD3, enables rapid and sensitive detection of Clostridioides difficile and—unexpectedly—Listeria monocytogenes, making it the first dual‐responsive DNAzyme for two unrelated bacterial pathogens. Its strong catalytic efficiency, pH‐tolerant activity, and modular trans‐acting design position it as a promising ...

Positive regulation of meiotic DNA double-strand break formation by activation of the DNA damage checkpoint kinase Mec1(ATR) [PDF]

open access: yes, 2013
During meiosis, formation and repair of programmed DNA double-strand breaks (DSBs) create genetic exchange between homologous chromosomes-a process that is critical for reductional meiotic chromosome segregation and the production of genetically diverse ...

Electroelution Into a Salt Trap: Reviving an Old‐School Approach to DNA Purification

open access: yesSmall Methods, Volume 10, Issue 5, 9 March 2026.
Electroelution into a salt cushion is a well‐established yet underutilized method of capturing gel‐purified nucleic acids. This Perspective discusses how this traditional method can be reengineered to meet the demands of next‐generation technologies, such as long‐read sequencing.

Development of Multi-Locus Variable Number Tandem Repeat Analysis for Outbreak Detection of Neisseria meningitidis [PDF]

open access: yes, 2006
Neisseria meningitidis is a major cause of septicemia and meningitis worldwide. Traditional typing methods like pulsed-field gel electrophoresis (PFGE) for identifying outbreaks are subjective and time consuming.

From Past to Present: Transformation of Food Safety Management and Food Safety Culture in the California Almond Industry

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 2, March 2026.
ABSTRACT The California almond industry underwent a remarkable transformation in food safety management and culture following outbreaks of salmonellosis associated with the consumption of raw almonds in 2000–2001 and 2003–2004. However, limited studies have examined these changes from a longitudinal perspective.

Antimicrobial Resistance in Salmonella Across Aquaculture, Seafood and Related Aquatic Environments: A Scoping Review With Exploratory Textual Analysis

open access: yesReviews in Aquaculture, Volume 18, Issue 2, March 2026.
This scoping review with textual analysis maps antimicrobial resistance in Salmonella across aquaculture, seafood, and related aquatic environments. Across 93 studies, recurrent MDR patterns suggest sentinel serotypes (S. Typhimurium, S. Newport) and a minimal antimicrobial susceptibility testing (AST) panel to guide matrix‐stratified One Health ...
