Structure/function analysis of PARP-1 in oxidative and nitrosative stress-induced monomeric ADPR formation. [PDF]

PLoS ONE, 2009
Poly adenosine diphosphate-ribose polymerase-1 (PARP-1) is a multifunctional enzyme that is involved in two major cellular responses to oxidative and nitrosative (O/N) stress: detection and response to DNA damage via formation of protein-bound poly ...

An arsenical analogue of adenosine diphosphate [PDF]

Biochemical Journal, 1978
An analogue of ADP was made in which the terminal phosphono-oxy group, -O-PO(OH)2, has been replaced by the arsonomethyl group, -CH2-AsO(OH)2. This compound cannot form a stable analogue of ATP because anhydrides of arsonic acids are rapidly hydrolysed, so that any enzyme that phosphorylates ADP and accepts this analogue as a substrate should release ...

NMR of $^{31}$P Nuclear Spin Singlet States in Organic Diphosphates [PDF]

, 2021
$^{31}$P NMR and MRI are commonly used to study organophosphates that are central to cellular energy metabolism. In some molecules of interest, such as adenosine diphosphate (ADP) and nicotinamide adenine dinucleotide (NAD), pairs of coupled $^{31}$P nuclei in the diphosphate moiety should enable the creation of nuclear spin singlet states, which may ...

The Role and Molecular Mechanism of P2Y12 Receptors in the Pathogenesis of Atherosclerotic Cardiovascular Diseases

Applied Sciences, 2021
The P2Y receptor family is a class of G protein-coupled receptors activated primarily by adenosine triphosphate (ATP), adenosine diphosphate (ADP), uridine triphosphate (UTP) and uridine diphosphate (UDP).

Transient behaviour towards the stable limit cycle in the Selkov model of Glycolysis: A physiological disorder [PDF]

Physica A 567 (2021) 125684, 2020
A simplified model for the complex glycolytic process was historically proposed by Selkov. It showed the existence of stable limit cycle as an example of Poincare-Bendixson theorem. This limit cycle is nothing but the time eliminated Lissajous plot of the concentrations of Adenosine-diphosphate (ADP) and Fructose-6-phosphate (F6P) of a normal/healthy ...

Constitutively released adenosine diphosphate regulates proplatelet formation by human megakaryocytes

Haematologica, 2012
Background The interaction of adenosine diphosphate with its P2Y1 and P2Y12 receptors on platelets is important for platelet function. However, nothing is known about adenosine diphosphate and its function in human megakaryocytes.Design and Methods We ...

Determination of Adenylate Nucleotides in Amphipod Gammarus fossarum by Ion-Pair Reverse Phase Liquid Chromatography: Possibilities of Positive Pressure Micro-Solid Phase Extraction

Separations, 2021
Adenine nucleotides—adenosine monophosphate, diphosphate, and triphosphate—are of utmost importance to all living organisms, where they play a critical role in the energy metabolism and are tied to allosteric regulation in various regulatory enzymes ...

Simultaneous quantification of 12 different nucleotides and nucleosides released from renal epithelium and in human urine samples using ion-pair reversed-phase HPLC [PDF]

, 2012
Nucleotides and nucleosides are not only involved in cellular metabolism but also act extracellularly via P1 and P2 receptors, to elicit a wide variety of physiological and pathophysiological responses through paracrine and autocrine signalling pathways.

Efficient adiabatic demagnetization refrigeration to below 50 mK with UHV compatible Ytterbium diphosphates $A$YbP$_2$O$_7$ ($A=$Na, K) [PDF]

Phys. Rev. Applied 20, 014013 (2023), 2023
Attaining milli-Kelvin temperatures is often a prerequisite for the study of novel quantum phenomena and the operation of quantum devices. Adiabatic demagnetization refrigeration (ADR) is an effective, easy and sustainable alternative to evaporation or dilution cooling with the rare and super-expensive $^3$He. Paramagnetic salts, traditionally used for
