The association between ANKH promoter polymorphism and chondrocalcinosis is independent of age and osteoarthritis : results of a case–control study [PDF]

open access: yes, 2014
Introduction: Chondrocalcinosis (CC) most commonly results from calcium pyrophosphate crystal deposition (CPPD). The objective of this study is to examine the association between candidate single-nucleotide polymorphisms (SNPs) and radiographic CC ...

Amorphous 1-D nanowires of calcium phosphate/pyrophosphate: a demonstration of orientated growth of amorphous minerals [PDF]

open access: yes, 2023
Amorphous inorganic solids are traditionally isotropic, thus, it is believed that they only grow into morphologies of nanospheres or irregular aggregates of nanoparticles.

Biohydrogen Production by the Thermophilic Bacterium Caldicellulosiruptor saccharolyticus: Current Status and Perspectives

open access: yesLife, 2013
Caldicellulosiruptor saccharolyticus is one of the most thermophilic cellulolytic organisms known to date. This Gram-positive anaerobic bacterium ferments a broad spectrum of mono-, di- and polysaccharides to mainly acetate, CO2 and hydrogen.

Arterial Calcifications in Patients with Liver Cirrhosis Are Linked to Hepatic Deficiency of Pyrophosphate Production Restored by Liver Transplantation

open access: yesBiomedicines, 2022
Liver fibrosis is associated with arterial calcification (AC). Since the liver is a source of inorganic pyrophosphate (PPi), an anti-calcifying compound, we investigated the relationship between plasma PPi ([PPi]pl), liver fibrosis, liver function, AC ...

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 ...

Pyrophosphate-Based Gemini Surfactants

open access: yes, 2016
Two series of pyrophosphate-based gemini surfactants [diimidazolium (1) and disodium P,P‘-dialkyl pyrophosphate (2) (a, R = 1-octyl; b, R = 1-dodecyl; c, R = 2-dodecyl)] were synthesized, along with a series of imidazolium monoalkyl phosphate surfactants

Women in science: Towards a copper-azophloxine inorganic complex for the selective naked-eye detection of pyrophosphate in water [PDF]

open access: yes, 2022
Indicator displacement assay is a well-known methodology reported for the detection of analytes. It is very easy to perform, especially with high school students.

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 ...
