Process study of ceramic membrane-coupled mixed-cell fermentation for the production of adenine

open access: yesFrontiers in Bioengineering and Biotechnology, 2022
In order to solve the problems of high complexity, many by-products, high pollution and difficult extraction of the existing adenine production process, in this study, ceramic membrane-coupled mixed cell fermentation was used to produce adenine while ...

Interaction of low-energy electrons with the purine bases, nucleosides, and nucleotides of DNA [PDF]

open access: yes, 2006
The authors report results from computational studies of the interaction of low-energy electrons with the purine bases of DNA, adenine and guanine, as well as with the associated nucleosides, deoxyadenosine and deoxyguanosine, and the nucleotide ...

Single-Step Charge Transport through DNA over Long Distances [PDF]

open access: yes, 2011
Quantum yields for charge transport across adenine tracts of increasing length have been measured by monitoring hole transport in synthetic oligonucleotides between photoexcited 2-aminopurine, a fluorescent analogue of adenine, and N_2-cyclopropyl ...

Adenine-rich diet: a potential mechanism for renal fibrosis progression

open access: yesExploration of Medicine, 2022
Chronic kidney disease (CKD) is a major health problem but there are many modalities to prevent and manage CKD progression. Diet is one of these factors, which needs to be evaluated more.

Ribose supplementation alone or with elevated creatine does not preserve high energy nucleotides or cardiac function in the failing mouse heart [PDF]

open access: yes, 2013
Background: Reduced levels of creatine and total adenine nucleotides (sum of ATP, ADP and AMP) are hallmarks of chronic heart failure and restoring these pools is predicted to be beneficial by maintaining the diseased heart in a more favourable energy ...

Radiological Evaluation of Huntington’s Disease: A Case Report [PDF]

open access: yesJournal of Clinical and Diagnostic Research
Huntington’s Disease (HD) is a rare neurodegenerative condition inherited in an autosomal dominant pattern, where Gamma Amino Butyric Acid-ergic (GABAergic) neurons in the basal ganglia progressively deteriorate.

Raman depolarization ratios in RNA and DNA are sensitive for sugar-base coupling [PDF]

open access: yes, 1995
Polarized and depolarized Raman spectra are obtained for a number of synthetic polynucleotides containing adenine, uracil, and thymine bases. The depolarization ratios are determined by two methods: (1) by dividing the -spectrum by the -spectrum and (2 ...
