ZrP₂O₇ as a Cathodic Material in Single-Chamber MFC for Bioenergy Production

Nanomaterials, 2022
The present work is the first investigation of the electrocatalytic performances of ZrP2O7 as a cathode in a single-chamber Microbial Fuel Cell (MFC) for the conversion of chemical energy from wastewater to bioelectricity. This catalyst was prepared by a

Influence of the radioactive concentration of the in vitro stability of Tc-99m(sn)-pyrophosphate [PDF]

Journal of the Serbian Chemical Society, 1999
The in vitro stability of 99m Tc(Sn)-pyrophosphate solutionwas examined in dependence on the preparation conditions of the samples, the radioactive concentration of 99m Tc in the kit and the time elapsed after labeling.

It Takes a Village: Multimodality Imaging of Cardiac Amyloidosis

Methodist DeBakey Cardiovascular Journal, 2022
Cardiac amyloidosis (CA) is the buildup and infiltration of amyloid plaque in cardiac muscle. An underdiagnosed form of restrictive cardiomyopathy, CA can rapidly progress into heart failure.

Contribution of PPi-hydrolyzing function of vacuolar H+-pyrophosphatase in vegetative growth of Arabidopsis: Evidenced by expression of uncoupling mutated enzymes

Frontiers in Plant Science, 2016
The vacuolar-type H+-pyrophosphatase (H+-PPase) catalyzes a coupled reaction of pyrophosphate (PPi) hydrolysis and active proton translocation across the tonoplast. Overexpression of H+-PPase improves growth in various plant species, and loss-of-function

TAMRA/TAMRA Fluorescence Quenching Systems for the Activity Assay of Alkaline Phosphatase

Sensors, 2017
We introduce two types of fluorescence-quenching assay for alkaline phosphatases (APs) by using a carboxytetramethyl-rhodamine (TAMRA)-labeled phosphate-binding tag molecule (TAMRA-Phos-tag).

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

Life, 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

Biomedicines, 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 ...

Pyrophosphate Arthropathy

Scandinavian 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 ...
