Abstract

In a randomized, double-masked, single drop study the effect of topical isosorbid-mononitrate (ISMO) 0.5% eye drops, the main metabolite of isosorbid-dinitrate, widely used in the treatment of coronary heart diseases, was studied in patients suffering from open angle glaucoma or ocular hypertension. There was no statistically significant IOP change within 8 hours posttreatment after topical administration of ISMO 0.5%. There were no side effects after application of the ophthalmic solution of ISMO 0.5%. There were no significant changes in blood pressure and pulse rate either. A 2% ophthalmic solution of ISMO was investigated with respect to a response on the aqueous humor dynamics in 10 healthy volunteers. Anterior chamber fluorophotometry revealed a mean increase in aqueous flow of 39% within 3 hours after topical application (P less than 0.01). However, in comparison to the placebo treated fellow eyes there were no statistical significant difference in aqueous humor flow during the time of investigation. There was a statistical significant reduction of IOP during the same time period (p less than 0.03) in all treated eyes.

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.
