Method of detecting and counting bacteria [PDF]
, 1976 An improved method is provided for determining bacterial levels, especially in samples of aqueous physiological fluids. The method depends on the quantitative determination of bacterial adenosine triphosphate (ATP) in the presence of nonbacterial ATP ...

Development of Carbon-Fiber Electrodes Modified for Electrochemical ATP Detection [PDF]
arXiv, 2018 Adenosine triphosphate (ATP) is a highly energetic molecule used as a coenzyme in the transfer of chemical energy required for the continuation of cellular metabolism. In addition, extracellular ATP has an important role in cell-to-cell communication in immune, nervous and vascular systems.

arXiv, 2017 Expressing the energy content of food as the heat energy released by its combustion is potentially misleading. Food is used to produce adenosine triphosphate (ATP). The free energy of conversion of ATP into adenosine diphosphate is used directly for processes such as muscular contraction, without the need for intermediate heat production. The number of

The regulatory switch of F1-ATPase studied by single-molecule FRET in the ABEL Trap [PDF]
, 2014 F1-ATPase is the soluble portion of the membrane-embedded enzyme FoF1-ATP synthase that catalyzes the production of adenosine triphosphate in eukaryotic and eubacterial cells. In reverse, the F1 part can also hydrolyze ATP quickly at three catalytic binding sites. Therefore, catalysis of 'non-productive' ATP hydrolysis by F1 (or FoF1) must be minimized

Advanced Science, EarlyView.This study investigates the metabolic vulnerabilities of glioblastoma (GBM), an aggressive brain tumor. Research demonstrates that iron chelation therapy, in combination with standard chemotherapy, significantly enhances the efficacy of treatment against resistant GBM cells in a 3D tumoroid model.

Purinergic mechanosensory transduction and visceral pain [PDF]
, 2009 In this review, evidence is presented to support the hypothesis that mechanosensory transduction occurs in tubes and sacs and can initiate visceral pain.

The role of adenosine triphosphate in migraine
Biomedicine & Pharmacotherapy, 1989 Classical migraine is associated with two distinct phases; an initial vasoconstriction followed by vasodilatation. The "purinergic" hypothesis for migraine was originally put forward in 1981 as a basis for the reactive hyperaemia and pain during the headache phase.

Intracellular compartmentalization of adenosine triphosphate.
Journal of Biological Chemistry, 1986 The intracellular distribution and diffusivity of adenosine triphosphate (ATP) was studied by cryomicrodissection of individual Rana pipiens oocytes. We measured ATP concentrations in the nucleus, in animal and vegetal hemisphere cytoplasm, and in an intracellular reference phase (iRP, a microinjected gelatin "organelle") which samples diffusive ATP ...
