Genome characteristics of facultatively symbiotic Frankia sp. strains reflect host range and host plant biogeography [PDF]

, 2007
Soil bacteria that also form mutualistic symbioses in plants encounter two major levels of selection. One occurs during adaptation to and survival in soil, and the other occurs in concert with host plant speciation and adaptation. Actinobacteria from the

Metabolic Origin, Role and Fate of the Denaturant Guanidine

Microbial Biotechnology, Volume 18, Issue 11, November 2025.
The origin of metabolic guanidine is largely a mystery. We suggest it is created when guanine‐containing nucleotides are oxidised by molecular oxygen instead of being broken down into urea as purines normally would. Guanidine may act as a signal to help cells control the level of reactive oxygen species.

Isolation and screening of l-asparaginase free of glutaminase and urease from fungal sp. [PDF]

, 2016
l-Asparaginase is a chemotherapeutic drug used in the treatment of acute lymphoblastic leukaemia (ALL), a malignant disorder in children. l-Asparaginase helps in removing acrylamide found in fried and baked foods that is carcinogenic in nature.

Electrochemical Point‐of‐Care Test for Assessing Serum Paracetamol Concentration: Comparison With Traditional Methods and Detection of Concomitant Drugs

Basic &Clinical Pharmacology &Toxicology, Volume 137, Issue 5, November 2025.
ABSTRACT Rapid serum paracetamol (acetaminophen) concentration measurement is essential in suspected intoxication, but centralized laboratory analyses often delay initiation of antidotal therapy. We studied the feasibility of a novel electrochemical single‐walled carbon nanotube/Nafion‐based point‐of‐care (POC) method in detecting paracetamol in 99 ...

Systematic Analysis of Gene Expression Differences between Left and Right Atria in Different Mouse Strains and in Human Atrial Tissue [PDF]

, 2011
Background: Normal development of the atria requires left-right differentiation during embryonic development. Reduced expression of Pitx2c (paired-like homeodomain transcription factor 2, isoform c), a key regulator of left-right asymmetry, has recently ...

Transposon mutagenesis in a hyper-invasive clinical isolate of Campylobacter jejuni reveals a number of genes with potential roles in invasion [PDF]

, 2010
Transposon mutagenesis has been applied to a hyper-invasive clinical isolate of Campylobacter jejuni, 01/51. A random transposon mutant library was screened in an in vitro assay of invasion and 26 mutants with a significant reduction in invasion were ...

Activation Energy of Organic Matter Decomposition in Soil and Consequences of Global Warming

Global Change Biology, Volume 31, Issue 9, September 2025.
Activation energy (Ea) is the minimum energy necessary for (bio)chemical reactions defining reaction rates, e.g., organic matter transformations in soil. Based on the Ea database of enzyme activities, CO2 production, heat release during soil incubation, and thermal oxidation of soil organic matter, we assess the Ea of biotic and abiotic transformation ...
