In a double-blind study on 22 patients with major depressive disorder the effects of lithium and clomipramine on signs and symptoms and on calcium and magnesium in plasma were compared. Ratings of antidepressant and side effects were performed by 2 psychiatrists at the end of a placebo period of 5-7 days and after treatment for 2 and 4 weeks. Psychopathology was rated by 15 reported and 4 observed items from the Comprehensive Psychopathological Rating Scale (CPRS). Eleven items present in 72-100% of the patients were used to evaluate the effect of the two drugs. After 2 weeks of treatment the rated scores dropped for more than half of the CPRS items. After 4 weeks the scores for all but one item were reduced in both groups. The sums of scores were significantly reduced after 2 weeks in both groups and after 4 weeks global scores were reduced as well. The drugs had notable and similar antidepressant effects. Lithium treatment was associated with fluctuations in calcium and magnesium levels in plasma not seen during clomipramine treatment. Serum prolactin increased during clomipramine treatment but was unaffected by lithium treatment. No correlations were found between the sum of rating scores and blood levels of drugs, prolactin...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.

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.
