Nuclear dynamics investigation of the initial electron transfer in the cyclobutane pyrimidine dimer lesion repair process by photolyases [PDF]
arXiv, 2016 Photolyases are proteins capable of harvesting the sunlight to repair DNA damages caused by UV light. In this work we focus on the first step in the repair process of the cyclobutane pyrimidine dimer photoproduct (CPD) lesion, which is an electron transfer (ET) from a flavine cofactor to CPD, and study the role of various nuclear degrees of freedom ...

In Plane Vibration of Pyrimidine and some Deuterated Pyrimidines [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 1991 On the basis of 102 assigned frequencies to in plane vibrations of pyrimidine, pyrimidine-2-d2, pyrimidine-2, 5-d2, pyrimidine-4,6-d2, pyrimidine-2,4,6-d3 and pyrimidine-d4, 35 valance force field constants including 14 principals and 21 interaction force constants are calculated.

Possible traces of resonance signaling in the genome [PDF]
arXiv, 2019 Although theories regarding the role of sequence-specific DNA resonance in biology have abounded for over 40 years, the published evidence for it is lacking. Here, the authors reasoned that for sustained resonance signaling, the number of oscillating DNA sequences per genome should be exceptionally high and that, therefore, genomic repeats of various ...

Metal‐organic framework derived porous structures towards lithium rechargeable batteries
EcoMat, Volume 5, Issue 2, February 2023., 2023 In this review, we discuss the characteristics of metal‐organic frameworks (MOFs) applied to lithium storage devices containing Li‐ion, Li‐sulfur, Li‐metal, and Li‐O2. We summarize the origin, nomenclature, and synthesis method of MOFs, and report on recent studies in which MOFs and MOF‐derived materials are applied to lithium rechargeable batteries ...

Studies on the Physiology of Pyrimidines. The Metabolism of the Pyrimidine Nucleosides
Experimental Biology and Medicine, 1929 The results of previous work by one of us1 indicated that the pyrimidines uracil and thymine, when fed in small amounts to dogs, are to a large extent metabolized. In the case of cytosine it was found that this substance was not utilized. It was partly excreted unchanged, partly deaminized and excreted in the form of uracil.These experiments were ...

Supramolecular Co(II)-[2 x 2] grids: Metamagnetic behavior in a single molecule [PDF]
Inorg. Chem. 45, 6535 (2006), 2006 The magnetic anisotropy of the supramolecular [2 x 2] grid [Co(II)4L4]8+, with a bis(bipyridyl)-pyrimidine based ligand L, was investigated by single-crystal magnetization measurements at low temperatures. The magnetization curves exhibit metamagnetic like behavior and are explained by the weak-exchange limit of a minimal spin Hamiltonian including ...

Solvable models of neighbor-dependent nucleotide substitution processes [PDF]
arXiv, 2005 We prove that a wide class of models of Markov neighbor-dependent substitution processes on the integer line is solvable. This class contains some models of nucleotide substitutions recently introduced and studied empirically by molecular biologists. We show that the polynucleotide frequencies at equilibrium solve explicit finite-size linear systems ...
