Metabolic alterations in human pulmonary artery smooth muscle cells treated with PDGF‐BB

Animal Models and Experimental Medicine, EarlyView.
Metabolic abnormalities are considered to play a key regulatory role in vascular remodeling of pulmonary arterial hypertension. We analyzed the metabolome in the culture supernatants of human pulmonary artery smooth muscle cells (PASMC) during the malignant proliferation phenotype transition via a targeted metabolomics method. Significant and extensive

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 ...

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 ...

Crystal structure of 2-butylsulfanyl-4,6-bis[(E)-styryl]pyrimidine

Acta Crystallographica Section E: Crystallographic Communications, 2015
In the title compound, C24H24N2S, the dihedral angles between the central pyrimidine ring and pendant benzene rings are 18.46 (6) and 5.95 (6)°. The butylsulfanyl side chain adopts a twisted conformation [S—C—C—C = 177.34 (10)° and C—C—C—C = 67.68 (18)°].

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 ...
