Testing of microbial isolate sensitivity in sterile soil after herbicide treatment

, 2015
Herbicides are commonly used in integrated weed management programs. Their application not only controls weed populations, it also affects microbial populations in soil, such as actinomycetes and azotobacters. This study examined the effects of three herbicides (nicosulfuron, metribuzin and glyphosate) on a tolerant actinomycete isolate (14/3) and a ...

Decoding IGLL5 Mutation‐Mediated BCR Signaling: A Novel Mechanism of CD8+ T Cell Exhaustion and Ocular MALT Lymphoma Progression

Advanced Science, EarlyView.
OAML harbors recurrent IGLL5 mutations that reinforce CD79A/CD79B‐associated BCR signaling. Mechanistic analysis of the S47G and A54G variants reveals induction of CXCL10/CXCL11, enhanced CD8+ T‐cell recruitment, and exhaustion‐associated dysfunction, supporting an immune‐tolerant niche.

Phenotypic Resistance Profiles, Biofilm Formation, and In Vitro Carbapenem-Sparing Antimicrobial Activity in Enterobacterales Causing Acute Pyelonephritis

Microorganisms
Empirical management of acute pyelonephritis in Eastern Europe is increasingly constrained by extended-spectrum β-lactamase (ESBL)-producing Enterobacterales and by uropathogen phenotypes—such as strong biofilm formation—which may further blunt ...

Transcription Factor Promiscuity Drives Regulatory Rewiring and Evolvability in Gene Networks in Bacteria

Advanced Science, EarlyView.
When a master transcription factor (TF) is lost, bacteria can rapidly rewire gene regulatory networks by co‐opting related regulators. Using experimental evolution in Pseudomonas fluorescens, we show that TF promiscuity (low‐level, non‐cognate binding) provides the raw material for rewiring. Successful co‐option follows a predictable hierarchy governed

Assessing the effect of model specification and prior sensitivity on Bayesian tests of temporal signal. [PDF]

Our understanding of the evolution of many microbes has been revolutionised by the molecular clock, a statistical tool to infer evolutionary rates and timescales from analyses of biomolecular sequences.

The effect of modulating membrane lipid composition on the thermal sensitivity of tumour cells in culture [PDF]

, 1989
The plasma membrane, which separates intracellular contents from extra cellular milieu, consists of a lipid bilayer comprising mainly phospholipids and cholesterol together with various functional proteins, which control the interaction of the cell with ...

Breaking the Mold: Towards Rapid and Cost-Effective Microbial Contamination Detection in Paints and Cosmetics Using ATP-Bioluminescence [PDF]

Traditional culture-based methods, though a “gold standard” for bacterial detection in various industrial sectors, do often not fulfill today’s high requirements regarding rapidity, on-site applicability, and cost-efficiency both during operation and ...

Synthetic Toll‐Like Receptors for Control of Innate Immunity With Far‐Red Light

Advanced Science, EarlyView.
Synthetic Toll‐like receptors (TLRs) are engineered by replacing their natural sensing regions with a far‐red‐light‐responsive module from a bacterial phytochrome. These synthetic receptors enable light‐controlled regulation of immune signaling in mammalian cells.
