Abstract

The first series of experiments showed that inhibition of the proteins synthesis followed by memory disorders, was reflected in decrease of the synaptosomal proteins fraction which was identified as the cholinoreceptor protein. Another series of experiments: training of rats to use unpreferred paw, showed the system acetylcholine-acetylcholinesterase to be directly connected with memory phenomena, and the synthesis of this enzyme to be induced by genetic apparatus. The third series of experiments showed that feeding of rats with small doses of aminoacids for a long time leads to regular shifts in distribution of both the aminoacids and the monoamines. The aminoacids increasing the brain activity were found to activate the production of cycle-adenyl acid. Those aminoacids which inhibit the brain activity, decrease the production of cyclic-AMP. Tranquilizers which decrease the level of monoamines and inhibit the brain activity, also decrease the production of cyclic-AMP. Antidepressants inhibiting MAO and increasing the level of monoamines in the brain, activate the production of cyclic-AMP. As the monoamines act via cyclic-AMP and the latter participates in suppression of DNA, the mechanism of involvement of the genetic apparatu...Continue Reading

COVID-19

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.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal Myelitis

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.

Alzheimer's Disease: MS4A

Variants within membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease by recent genome-wide association studies. Here is the latest research.
