The following parameters are recommended for activity determination of FDPase by release of inorganic phosphate at 37 degrees C of enzyme from liver and kidneys of swine: pH 7.5, 2 mMol concentration of fructose-1,6-diphosphate, 5 mMol concentration of Mg ions, and ten minutes of incubation. When the activity of FDPase was analysed with temperatures of 22 degrees C, and 45 degrees C, rises were recorded up to the highest temperature. ADTA was strongly activating along with 2 mMol of Mg ions in a test arrangement of 5 mMol concentration. Manganese, zinc, and cobalt ions are strong activators even in low concentrations (0.2 or 1.0 mMol), whereas copper, cadmium, and mercury ions are strong inhibitors of the enzyme. Average activities of FDPase were analysed by means of the optical test in the liver and kidneys of fetuses aged 98 days. They were 1.79 or 0.38 units in one gram of tissue. In pigs for slaughter they had been 2.06 or 3.58 units in one gram of tissue.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Synapse Loss as Therapeutic Target in MS

As we age, the number of synapses present in the human brain starts to decline, but in neurodegenerative diseases this occurs at an accelerated rate. In MS, it has been shown that there is a reduction in synaptic density, which presents a potential target for treatment. Here is the latest research on synapse loss as a therapeutic target in MS.
