Purine and pyrimidine bases as growth substances for lactic acid bacteria [PDF]

open access: yes, 1941
In 1936 Richardson (1) showed that uracil was essential for the anaerobic growth of Staphylococcus aureus, but not for aerobic growth of the same organism.

Effect of Cyclic Heat Exposure on the Growth Performance and Metabolism of Broilers Fed Palm Kernel Meal

open access: yesAnimal Research and One Health, EarlyView.
The aim of our study is to evaluate the interaction between HS and the incorporation of PKM in broiler chicken diets, as well as its effect on growth performance and metabolism. Based on the results obtained, PKM supplementation failed to mitigate the adverse effects of heat stress in broiler chickens. ABSTRACT The aim of this study was to evaluate the

A Metabolomic Signature Predicts Gout Flare Clinical Outcome Associated With Colchicine Prophylaxis

open access: yesArthritis &Rheumatology, EarlyView.
Objective This study investigated that serum metabolomics, before urate‐lowering therapy (ULT) initiation, could serve as a biomarker for responsiveness to colchicine prophylaxis in patients with gout commencing treat‐to‐target ULT. Methods We studied a multicenter prospective cohort (n = 409) initiating treat‐to‐target ULT plus colchicine prophylaxis.

Purine and carbohydrate availability drive Enterococcus faecalis fitness during wound and urinary tract infections

open access: yesmBio
Enterococcus faecalis is commonly isolated from a variety of wound types. Despite its prevalence, the pathogenic mechanisms of E. faecalis during wound infection are poorly understood. Using a mouse wound infection model, we performed in vivo E. faecalis

First-principles GW calculations for DNA and RNA nucleobases

open access: yes, 2011
On the basis of first-principles GW calculations, we study the quasiparticle properties of the guanine, adenine, cytosine, thymine, and uracil DNA and RNA nucleobases.

Inosine‐Triphosphate‐Pyrophosphatase Activity as a Potential Predictor of Methotrexate Remission in Juvenile Idiopathic Arthritis

open access: yesArthritis &Rheumatology, EarlyView.
Objective Methotrexate (MTX) is the first‐line therapy for juvenile idiopathic arthritis (JIA), but up to 40% of patients do not respond to it. Low inosine triphosphate pyrophosphatase (ITPA) activity has been associated with reduced clinical remission. We investigated the role and underlying mechanisms of ITPA in vitro. Methods ITPA enzymatic activity

E. coli genetically modified for purine nucleobase release promotes butyrate generation and colonic wound healing during DSS insult

open access: yesGut Microbes
The gut microbiota transforms energy stored as undigestible carbohydrates into a remarkable number of metabolites that fuel intestinal bacterial communities and the host tissue.
