The effect of the prostaglandin inhibitors, aspirin and indomethacin and of prostaglandins PGE1 and PGE2 on spermatogenesis in the mature male mouse has been studied. Aspirin at 100 mg/kg and at 200 mg/kg, and indomethacin at 1.0 mg/kg given orally twice a day for fifteen days produced a marked increase in spermatogenesis. The number of step 7 spermatids increased significantly over controls at about the same rate in all three groups. No significant changes in seminal vesicle weight or testicular weight was noted, although testicular weight did show an increase. Administration of prostaglandins E1 and E2 subcutaneously in doses of either 2 mg/kg or 3 mg/kg once a day for fifteen days produced a marked decrease in spermatogenesis. Step 7 spermatids decreased significantly at both dosage levels of PGE2 and at the higher dosage level of PGE1. Spermatocyte showed a significant decrease at the higher dose of PGE2. Testicular weight showed a significant decrease at the higher dose of PGE2. Seminal vesicle weight showed a significant decrease at the lower dose of PGE1 and at the higher dose of PGE2. Epididymal weight decreased at the higher dose of PGE2. Increased numbers of exfoliated immature germ cells and mature spermatozoa were o...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.
