Abstract

Thyrotropin-releasing hormone tartrate (TRH-T) was administered in 17 cases of organic brain lesions and 2 cases of disturbed mental activity (psychical depression), and its effect, mainly on the level of consciousness and electroencephalogram, was examined. Ten consecutive administrations of 0.5--1.0 mg/day TRH-T, as TRH, resulted in improvement of disturbance of consciousness in 8 of 16 cases. This effect was not necessarily correlated with the degree of disturbance or the site of the lesion. Improvement was seen even in those cases where disturbance of consciousness had been fixed over a long period. The effect on the electroencephalogram was small and did not parallel the degree of improvement of the level of consciousness. Abnormal TSH and thyroid hormone values were not seen despite the continued administration of TRH-T. These results would appear to indicate that the continuous administration of TRH-T has a mild activating effect directly on the central nervous system, and not through the endocrine mechanism, and exerts no damage on the internal environment in vivo.

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.

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.

Artificial Intelligence in Cardiac Imaging

Artificial intelligence (ai) techniques are increasingly applied to cardiovascular (cv) medicine in cardiac imaging analysis. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.
