Aggregation-Induced Emission of Au/Ag Alloy Nanoclusters for Fluorescence Detection of Inorganic Pyrophosphate and Pyrophosphatase Activity

open access: yesFrontiers in Bioengineering and Biotechnology, 2021
The development of sensitive and accurate detection of inorganic pyrophosphate (PPi) and pyrophosphatase activity (PPase) is important as they play vital roles in biological systems.

Pyrophosphate Arthropathy

open access: yesScandinavian Journal of Rheumatology, 1979
Pyrophosphate arthropathy has a wide spectrum of clinical symptoms and is a common cause of synovitis in the elderly. The acute "pseudogout" attack is the most commonly recognized, but chronic synovitis might be just as prevalent. Familial pyrophosphate arthropathy with a dominant autosomal heredity is a rare form, with an earlier debut and a more ...

Chronic Kidney Disease-Induced Arterial Media Calcification in Rats Prevented by Tissue Non-Specific Alkaline Phosphatase Substrate Supplementation Rather Than Inhibition of the Enzyme

open access: yesPharmaceutics, 2021
Patients with chronic kidney disease (CKD) suffer from arterial media calcification and a disturbed bone metabolism. Tissue-nonspecific alkaline phosphatase (TNAP) hydrolyzes the calcification inhibitor pyrophosphate (PPi) into inorganic phosphate (Pi ...

Stereochemistry at C-1 of geranyl pyrophosphate and neryl pyrophosphate in the cyclization to (+)- and (-)-bornyl pyrophosphate.

open access: yesJournal of Biological Chemistry, 1985
(1R)-1-3H-labeled and (1S)-1-3H-labeled geranyl pyrophosphate and neryl pyrophosphate were prepared from the corresponding 1-3H-labeled aldehydes by a combination of enzymatic and synthetic procedures. Following admixture with the corresponding 2-14C-labeled internal standard, each substrate was converted to (+)-bornyl pyrophosphate and (-)-bornyl ...

RETRACTED: Pyrophosphate modulates plant stress responses via SUMOylation

open access: yeseLife, 2019
Pyrophosphate (PPi), a byproduct of macromolecule biosynthesis is maintained at low levels by soluble inorganic pyrophosphatases (sPPase) found in all eukaryotes. In plants, H+-pumping pyrophosphatases (H+-PPase) convert the substantial energy present in

Oxidative Phosphorus Chemistry Perturbed by Minerals

open access: yesLife, 2022
Life is a complex, open chemical system that must be supported with energy inputs. If one fathoms how simple early life must have been, the complexity of modern-day life is staggering by comparison. A minimally complex system that could plausibly provide

The crystal structure of KScP2O7

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2020
Single crystals of KScP2O7, potassium scandium diphosphate, were grown in a borate flux. The title compound crystallizes isotypically with KAlP2O7 in space-group type P21/c, Z = 4.

Myocardial damage of the entire ventricular region in a patient with acute myocardial infarction [PDF]

open access: yesAsia Oceania Journal of Nuclear Medicine and Biology, 2020
Technetium-99m-pyrophosphate (99mTc-PYP) has been used, in combination with thallium-201, to estimate the site and extent of myocardial infarcts. We report a case of acute myocardial infarction with severe coronary disease in which the distribution of ...
