The effect of betadrenol on examination anxiety was tested in a double-blind study simulating "examination situations". The sample consisted of 60 normal students. After a test examination without prior treatment, each subject was given a single dose of either 40 or 100 mg betadrenol, or a benzodiazepine derivative at the recommended dosage, or a placebo. The test was repeated one hour later. Heart rate, blood pressure and skin resistance were measured continually throughout the progressively complicated psychological test. The increase in the heart rate was significantly lower in the betadrenol-treated subjects than in those given benzodiazepine or a placebo. The behaviour of the blood pressure was similar. Significant improvements in subjective condition and skin resistance in response to betadrenol were contrasted with deterioration after benzodiazepine, and no change after placebos. Improvement in mental alertness in the betadrenol group differed significantly from that in the benzodiazepine group, and there was also an improving trend in reactions. This shows that betadrenol can subdue examination anxiety. Betadrenol was far more effective than a benzodiazepine derivative in all the parameters tested, including psychophysi...Continue Reading

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.
