Adenine and Thymine Effect on Quartz Dissolution at Different Artificial Seawaters

open access: yesOrbital: The Electronic Journal of Chemistry, 2018
According to Bernal (1951) minerals may have played important roles in the origin of life such as: protect biomolecules against degradation by UV radiation or hydrolysis, pre-concentrate biomolecules from prebiotic seas and formation of polymers.

A porous material of cross-linked adenine-polyethylene glycol diglycidyl ether for copper ion adsorption

open access: yesMaterials Research Express, 2021
A porous material (PEA) was prepared by the ring opening polymerization of polyethylene glycol diglycidyl ether with adenine in a simple sol-gel method. The structure and composition of PEA were characterized by SEM, FT-IR, BET and XRD.

Can adenine nucleotides predict primary nonfunction of the human liver homograft? [PDF]

open access: yes, 1994
Sixty-eight primary liver grafts were analyzed to see whether adenine nucleotides (AN: ATP, ADP, and AMP) or purine catabolites (PC: adenosine, inosine, hypoxanthine, and xanthine) of tissue or effluent can predict primary graft nonfunction.

Detection of Guanine and Adenine Using an Aminated Reduced Graphene Oxide Functional Membrane-Modified Glassy Carbon Electrode

open access: yesSensors, 2017
A new electrochemical sensor based on a Nafion, aminated reduced graphene oxide and chitosan functional membrane-modified glassy carbon electrode was proposed for the simultaneous detection of adenine and guanine. Fourier transform-infrared spectrometry (

Sensitive Silver-Enhanced Microplate Apta-Enzyme Assay of Sb3+ Ions in Drinking and Natural Waters

open access: yesMolecules, 2023
The toxic effects of antimony pose risks to human health. Therefore, simple analytical techniques for its widescale monitoring in water sources are in demand. In this study, a sensitive microplate apta-enzyme assay for Sb3+ detection was developed.

The influence of adenine and benzyladenine on rooting and development of Fuchsia hybrida cuttings

open access: yesActa Agrobotanica, 2012
Cytokinins are a group of plant hormones stimulating, among others, axillary bud formation and inhibiting rhizogenesis. Adenine, their common component, often expresses cytokinin-like activity in plant development.
