Indices of noradrenergic output in depression

Abstract

Concentrations of plasma norepinephrine (NE) and plasma-3-methoxy-4-hydroxyphenylglycol (MHPG), blood pressure, and heart rate were measured on 2 days in 25 depressed patients and 25 controls. Comparisons were made between patients and controls, and also between days for both groups, to determine the short-term stability of these measures. The means of the plasma and urinary noradrenergic metabolite measures were not significantly different between groups. The variance of plasma MHPG, plasma NE, and mean blood pressure was greater in the depressed patients than in controls. Blood pressure, plasma MHPG, and plasma NE were relatively stable as suggested by the significant correlations between the 2 days for each of these variables. Plasma NE, plasma MHPG, and the sum of the deaminated urinary metabolites (MHPG and vanillylmandelic acid) were significantly intercorrelated. These results support other data in suggesting that plasma concentrations of NE and MHPG may be useful measures of noradrenergic activity, but may not consistently distinguish depressed patients from controls.

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.
