Influence of Kynurenine, Neopterin, Noradrenaline and Pyridoxal-5-Phosphate on Cholesterol and Phospholipid Content and Phospholipid Biosynthesis in vitro

Pteridines, 1993
Incorporation of fatty acids into phospholipids has been investigated using samples of rat liver tissue homogenate, Krebs-Ringer-phosphate buffer (pH = 7.4) containing 0.3% albumin, fatty acid mixture and glyceroL The addition of L-kynurenine (4 nmol/g ...

1H‐Nuclear Magnetic Resonance Metabolic Profiling of Pantaneiro and Curraleiro Beef Breeds: Unveiling Adaptation Mechanisms in Brazilian Livestock

New Zealand Journal of Agricultural Research, Volume 69, Issue 1, February 2026.
This study provides the first metabolomic characterization of serum from Pantaneiro and Curraleiro beef cattle, unveiling their unique adaptations to the Pantanal and Cerrado biomes of Brazil. Blood was collected during the summer season to capture metabolic responses to extreme environmental conditions, including high temperatures and varying humidity.

Association Between Habitual Food Intake and Energy Metabolism‐Related Urine Metabolites in Female Soccer Players

Molecular Nutrition &Food Research, Volume 70, Issue 3, 13 February 2026.
We studied the relationship between nutrient intake and substances found in urine, both involved in energy production, in female soccer players. We assessed the players' usual diet before the season and collected urine samples before and after matches.

Investigating operational stability and causes of cofactor release in fold type I amine transaminase

Protein Science, Volume 35, Issue 2, February 2026.
Abstract Amine transaminases (ATAs) are pyridoxal phosphate (PLP) dependent biocatalysts frequently employed in chiral amine synthesis. Yields of ATA‐catalyzed reactions often suffer from low enzyme operational stability due to weak interactions between the ATA and the aminated cofactor pyridoxamine phosphate (PMP), which can leak from the active site ...

The Role of the Gut Microbiome in the Complex Network of Frailty Syndrome and Associated Comorbidities in Aging

Aging Cell, Volume 25, Issue 2, February 2026.
This study analyzed gut microbiota in older adults with and without Frailty Syndrome by 16S rRNA gene sequencing and metagenomics. Frailty was associated with altered microbial composition, metabolic functions, and increased antimicrobial resistance, whereas non‐frail individuals showed healthier profiles.

Oxygen needs sulfur, sulfur needs oxygen: a relationship of interdependence

The EMBO Journal
Oxygen and sulfur, both members of the chalcogen group (group 16 elements), play fundamental roles in life. Ancient organisms primarily utilized sulfur for energy metabolism, while the rise in atmospheric oxygen facilitated the evolution of aerobic ...

Selection for Postponed Senescence in Drosophila melanogaster Reveals Distinct Metabolic Aging Trajectories Modifiable by the Angiotensin‐Converting Enzyme Inhibitor Lisinopril

Aging Cell, Volume 25, Issue 2, February 2026.
Assessment of oxygen consumption rates in young, middle‐aged, and old flies from the Drosophila B lines and long‐lived O lines revealed a significant increase in metabolic rate with aging only in B flies. Lisinopril prevented the age‐related rise in metabolic rate in B female flies.

Genome Sequence and Population Genomic Analysis of Cronartium quercuum f.sp. fusiforme

Forest Pathology, Volume 56, Issue 1, February 2026.
ABSTRACT Fusiform rust, caused by Cronartium quercuum f. sp. fusiforme (Cqf), is the most severe disease of planted southern pines in the south‐eastern United States. Despite the critical role pathogen genomics play in disease outcomes, the population structure and genetic variability of Cqf remain poorly characterised.
