A sulfur-containing nucleoside antibiotic from Photorhabdus [PDF]
We report the discovery of 4′-thiothymidine (4′sT), a sulfur-containing nucleoside antibiotic produced by the nematode symbiont Photorhabdus asymbiotica.

Systemic metabolic changes in acute and chronic lymphocytic choriomeningitis virus infection [PDF]
Objective: Viral infection of cells leads to metabolic changes, but how viral infection changes whole-body and tissue metabolism in vivo has not been comprehensively studied. In particular, it is unknown how metabolism might be differentially affected by

Molecular Basis of the Slow Growth of Mycoplasma hominis on Different Energy Sources
Mycoplasma hominis is an opportunistic urogenital pathogen in vertebrates. It is a non-glycolytic species that produces energy via arginine degradation. Among genital mycoplasmas, M.

Thymidine plaque autoradiography of thymidine kinase-positive and thymidine kinase-negative herpesviruses [PDF]
Plaques formed by herpes simplex virus (HSV), pseudorabies virus, and varicella-zoster virus were studied by plaque autoradiography after [14C]thymidine labeling. Standard thymidine kinase-positive (TK+) viruses and TK- mutants of HSV types 1 and 2 and pseudorabies virus were studied, including cell cultured viruses and viruses isolated from animals ...

Nanoparticles Based on Novel Carbohydrate-Functionalized Polymers
Polymeric nanoparticles can be used for drug delivery systems in healthcare. For this purpose poly(lactic-co-glycolic acid) (PLGA) and poly(ethylene glycol) (PEG) offer an excellent polymeric matrix.

Thymidine uptake, thymidine incorporation, and thymidine kinase activity in marine bacterium isolates [PDF]
One assumption made in bacterial production estimates from [3H]thymidine incorporation is that all heterotrophic bacteria can incorporate exogenous thymidine into DNA. Heterotrophic marine bacterium isolates from Tampa Bay, Fla., Chesapeake Bay, Md., and a coral surface microlayer were examined for thymidine uptake (transport), thymidine incorporation,

Thymidine kinase 1 through the ages: a comprehensive review
Proliferation markers, such as proliferating cell nuclear antigen (PCNA), Ki-67, and thymidine kinase 1 (TK1), have potential as diagnostic tools and as prognostic factors in assessing cancer treatment and disease progression. TK1 is involved in cellular

Altered Thymidine Metabolism Due to Defects of Thymidine Phosphorylase [PDF]
Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) is an autosomal recessive human disease due to mutations in the thymidine phosphorylase (TP) gene. TP enzyme catalyzes the reversible phosphorolysis of thymidine to thymine and 2-deoxy-D-ribose 1-phosphate. We present evidence that thymidine metabolism is altered in MNGIE.
