Biosensor measurement of purine release from cerebellar cultures and slices [PDF]

open access: yes, 2010
We have previously described an action-potential and Ca2+-dependent form of adenosine release in the molecular layer of cerebellar slices. The most likely source of the adenosine is the parallel fibres, the axons of granule cells. Using microelectrode

Hoogsteen base pairs proximal and distal to echinomycin binding sites on DNA [PDF]

open access: yes, 1987
Forms of the DNA double helix containing non-Watson-Crick base-pairing have been discovered recently based on x-ray diffraction analysis of quinoxaline antibiotic-oligonucleotide complexes.

Electronic Spectroscopy of Isolated DNA Polyanions [PDF]

open access: yes, 2018
In solution, UV-vis spectroscopy is often used to investigate structural changes in biomolecules (i.e., nucleic acids), owing to changes in the environment of their chromophores (i.e., the nucleobases).

The exercise sex gap and the impact of the estrous cycle on exercise performance in mice

open access: yesScientific Reports, 2018
Exercise physiology is different in males and females. Females are poorly studied due to the complexity of the estrous cycle and this bias has created an exercise sex gap.

A New Class of Nucleosides. Synthesis, Reactivity and Biological Activity of Keto-Hexose Nucleosides

open access: yesCHIMIA, 1975
Direct oxydation of sterically hindered hexosyl purines led to keto-hexosylpurines, important synthetic intermediates. The first unsaturated keto-nucleosides have also been obtained by acetylation of the corresponding keto-hexosyl purines.

Purinergic Signalling in Inflammatory Renal Disease

open access: yesFrontiers in Physiology, 2013
Extracellular purines have a role in renal physiology and adaption to inflammation. However, inflammatory renal disease may be mediated by extracellular purines, resulting in renal injury.

P2X7 Receptor Upregulation in Huntington’s Disease Brains

open access: yesFrontiers in Molecular Neuroscience, 2020
Huntington’s disease (HD) is a fatal degenerative disorder affecting the nervous system. It is characterized by motor, cognitive, and psychiatric dysfunctions, with a late onset and an autosomal dominant pattern of inheritance.

Surface-enhanced Raman spectroscopy of DNA bases [PDF]

open access: yes, 1986
A Raman microprobe has been used to measure the surface-enhanced Raman spectra of adenine, guanine, cytosine and thymine. Comparison of the SERS spectrum with solution spectra shows that some line positions are not influenced by the adsorption process ...

Elevated Level of DNA Damage and Impaired Repair of Oxidative DNA Damage in Patients with Recurrent Depressive Disorder [PDF]

open access: yes, 2015
Background: Depressive disorder (DD), including recurrent DD (rDD), is a severe psychological disease, which affects a large percentage of the world population.
