MHPG excretion and EEG sleep in primary depression

Psychiatry Research
D J KupferJ F Neil


Measures of daily urinary 3-methoxy-4-hydroxyphenylglycol (MHPG) excretion and electroencephalographic (EEG) sleep data were examined in 30 patients hospitalized for depression. This sample (mean age = 35 years) comprised 17 females and 13 males, all of whom were drug-free for 2 weeks and met Research Diagnostic Criteria for primary depressive disorder. Data analyses were conducted on the entire group, as well as the male, female, unipolar, and recurrent subgroups. No significant relationships were observed between total MHPG excretion and rapid eye movement (REM) or non-REM sleep variables. In particular, the absence of an interrelatedness of MHPG and REM sleep fails to confirm earlier findings in a smaller patient sample. These results, therefore, raise new questions about the proposed role of central noradrenergic activity in the mediation of REM sleep in depression.

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.

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

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.
