Effect of additions of the carbon and nitrogen sources on the NADP+ and NAD+ level in the mycelium of a producing strain of P. nigricans Thom

I G Rogal'


The levels of NADP+ and NAD+ in the mycelium of a cultured strain of P. nigricans Thom grown on the mineral medium with 2 per cent of glucose were studied as dependent on the time and method of addition of glucose. NaNO3 or their mixture to the medium, i. e. a single addition simultaneously with the spore inoculation or on the 7th day of the culture development, divided additions on the 5th--7th days. It was shown that addition of the above sources simultaneously with inoculation affected the levels of both dinucleotides by the 5th and 8th days. Analogous additions on the 7th day in 24 hours decreased the level of NAD+, while the NADP+ concentration increased after addition of a mixture of glucose and NANO3 and remained unchanged on their separate addition. When the above sources were added in divided doses the level of NADP+ increased till the 7th day and that of NAD+ till the end of the experiment (the 8th day).

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.

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.
